More than 400 DDos attacks identified using new attack vector – LDAP

Hackers use misconfigured LDAP servers – Connectionless Lightweight Directory Access Protocol (CLDAP) – to provide a means to launch DDoS attacks.

More than 400 DDoS attacks taking advantage of misconfigured LDAP servers have been spotted by security researchers.

CLDAP DDoS attacks use an amplification technique, which takes advantage of the Connectionless Lightweight Directory Access Protocol (CLDAP): LDAP is one of the most widely used protocols for accessing username and password information in databases like Active Directory, which is integrated in many online servers. When an Active Directory server is incorrectly configured and exposes the CLDAP service to the Internet it is vulnerable to be leveraged to perform DDoS attacks.

Since its discovery in October 2016, researchers at Corero Network Security have observed a total of 416 CLDAP DDoS attacks, most of which are hosting and internet service providers. The largest attack volume recorded was 33 Gbps, with an average volume of 10 Gbps. The attacks averaged 14 minutes long in duration.

“These powerful short duration attacks are capable of impacting service availability, resulting in outages, or acting as a smoke screen for other types of cyber-attacks, including those intended for breach of personally identifiable data,” said Stephanie Weagle, vice president of marketing at Corero Network Security, in a blog post.

Stephen Gates, chief research intelligence analyst from NSFOCUS, told SC Media UK that in the quest to find new means of launching DDoS attacks, hackers have once again found open devices on the Internet running weak protocols that can be exploited for their personal gain.

“However, like any other reflective DDoS attack campaign, the number of available reflectors is of critical importance.  In addition, the amplification factor those reflectors afford is the second stipulation,” he said.

“In this case, the number of open devices on the Internet running CLDAP is relatively small, in comparison to open DNS and NTP reflectors; yet the amplification factor is respectable (~70x).  Surely, this attack technique is new, but it is not the worse seen so far.  This vector will likely be used in combination with other reflective attack techniques, and rarely used on its own.   Until the world’s service providers fully implement BCP-38, similar discoveries and resulting campaigns will continue to plague us all.”

Bogdan Botezatu, senior E-Threat analyst at Bitdefender, told SC that a CLDAP attack is designed around third parties: an entity running a misconfigured instance of CLDAP, a victim and an attacker.

“The attacker would ask the CLDAP infrastructure to retrieve all the users registered in the Active Directory. Because the attacker makes this query look like it was initiated by the victim by replacing the originating IP address with the victim’s, the CLADP service will actually send the answer to the victim,” he said.

“Subsequently, the victim finds itself being bombarded with the information they did not request. If the attacker can harness enough power, the victim’s infrastructure will crash under a load of unsolicited information.”

He said that organisations could deploy strong, restrictive firewall policies for inbound traffic. “Load balancing and specialised hardware can also help organisations absorb the impact,” said Botezatu.

Why hardware configurations could be the downfall of IoT

According to Trend Micro, The Internet of Things is opening up new opportunities for businesses as well as introducing a new era of convenience for consumers. However, in a blogpost, they warn of issues that can lead to the downfall of IoT and called for countries stiving to be a smart nation to be wary.

More than 24 billion IoT devices will connect to each other and the internet by 2020, according to Business Insider, and that’s a conservative estimate. The Motley Fool noted that other tech giants are predicting anywhere from 50 billion to 200 billion IoT devices within the next three years.

One thing is clear: The IoT is going to be big, and require a lot of management. After all, handling devices the wrong way could leave security gaps in your network. Hardware configurations could be the downfall of IoT, and it’s important for you to enable your systems appropriately.

Systems at risk

Most devices, including routers and printers, come with preset, easy passwords and inactivated security capabilities. A number of organizations may simply install this hardware without changing the standard authorizations, leaving significant holes that attackers can exploit. This type of situation is only magnified by the number of active IoT devices. After all, who wants to configure every sensor or create a firewall for their coffee maker? However, you must do exactly that to enable IoT without compromising security.

IoT technology is still developing, and you must ask critical questions to understand how these devices handle your sensitive information. The Global Privacy Enforcement Network Privacy Sweep found that it wasn’t clear how IoT devices collected, used and disclosed information. Many companies also neglect to explain how user data would be secured or how to delete personal information. With so many entry points to your network, your system could be at risk if you don’t have definitive answers concerning their requirements and capabilities.

“If you think your IoT devices aren’t at risk, you’re wrong.”

Sitting targets for malicious attacks

Unsecured IoT devices are gateways for hackers to stroll into your critical business systems and execute attacks on a larger scale. In fact, major internet services including Twitter, Spotify and Netflix were disrupted when an attacker leveraged IoT devices to deliver a series of massive DDoS attacks to Dyn. According to Fast Company, the hacker leveraged the digital traffic from internet-enabled hardware and sent the noise to the domain name service provider, disrupting its ability to translate addresses into IP networks. Hundreds of thousands of cameras, routers, DVRs and other household appliances were used to carry out this attack. Security experts had warned that such a situation could occur, serving as a reminder why hardware configurations are critical for business and user security.

If you think your IoT devices aren’t at risk, you’re wrong. Attackers can use tools like Shodan to easily search for exposed cyber assets. Trend Micro noted this system can show a hacker any connected device’s IP address, application and firmware versions as well as other critical information to make it easier to compromise. This research also found web servers, webcams, wireless access points and routers were the most unsecured cyber assets in the top 10 most populous U.S. cities.

Protecting your IoT devices

Security capabilities across IoT devices will only continue to improve, but in the meantime, organizations must take steps to protect this hardware. The first step is to configure your equipment correctly to your business and set passwords that will be difficult for a hacker to guess. You should also leverage data breach systems to detect unusual behavior within your network as it occurs. This solution will help catch malicious access to your IoT devices, enabling you to act quickly to reinstate and improve security.

Recognizing the New Face of Cyber-Security

Threats, risks and dangers related to cyber-security are changing. CIOs must respond with a well-defined strategy and the right mix of processes and tools.

Over the past few years, digital technologies have rippled through the business world and unleashed unprecedented innovation and disruption. Yet today’s technology framework also has put businesses in the crosshairs and created new levels of risk.

No longer are cyber-threats thwarted by clearly defined perimeters such as firewalls. No longer are malware and cyber-attacks blocked by traditional security tools designed to identify specific viruses and code. “It’s an entirely different landscape,” observes Oswin Deally, vice president of cyber-security at consulting firm Capgemini.

To be sure, mobility, clouds, the internet of things (IoT) and the increasingly interconnected nature of business and IT systems have radically changed the stakes. There’s a growing need for security transformation.

Yet, at the same time, attacks are becoming more insidious and sophisticated. Phishing, spear-phishing, whaling, ransomware, hacking, hacktivism and corporate espionage are now mainstream problems. Data breaches and DDoS attacks are a daily concern.

“Cyber-security has moved from a compliance and regulatory topic to front-page headline news,” says Dan Logan, director of enterprise and security architecture for Tata Consultancy Services (TCS).

No Space Is Safe

The scope of today’s cyber-security challenge is mind-boggling. Gartner predicts that more than 8.4 billion IoT devices will be used in 2017, and the number will swell to more than 20 billion by 2020. Meanwhile, 74 percent of organizations now store some, if not all, sensitive data in the public cloud, according to a February 2017 Intel Security study.

Not surprisingly, the stakes are growing, and achieving digital transformation while ensuring security is not a simple task. An October 2016 Ponemon Institute study found that the average cost of cyber-crime to a large organization in the United States rose to more than $17 million in 2016.

An interconnected world with intertwined data means that threats can come from anywhere at any time. Business disruption, information loss, a diminished brand image and revenue, and damage to equipment are constant risks. Nevertheless, organizations are struggling to keep up.

Ponemon points out that only 39 percent of companies deploy advanced backup and recovery operations, though it reduces the average cost of cyber-crime by nearly $2 million. Similarly, only 28 percent of companies have a formal information governance program, though this typically reduces the cost of cyber-crime by nearly $1 million.

Capgemini’s Deally says that a starting point for dealing with today’s threat landscape is to recognize that there are two primary areas to focus on: business-driven events and threat-driven events. The former revolves around things like digital commerce, innovation, intellectual property, products and supply chains that present targets and create risks for the enterprise. The latter encompasses attack methods and vectors, including email, mobile devices, the IoT, and other systems and software.

“It is becoming more and more of a borderless world where the devices that drive productivity also represent risk,” he points out.

CIOs and other enterprise leaders must understand business and technology intersection points and how they introduce risks at various levels—from application security to APIs and network design to clouds. It’s also important to clearly understand business and data assets and identify priorities in terms of value, sensitivity and risk.

Not all data is created equal and not all systems require equal protection. This approach, when layered over specific industry risks, begins to deliver some clarity about how and where to focus a cyber-security strategy and select the right protections and processes.

o be sure, cyber-security must take a multilayered approach, and it must focus on defense-in-depth. One of today’s challenges is that intruders may gain entry to a network through a vulnerability or breach and worm their way through systems and files over a period of weeks, months or years.

These advanced persistent threats (APTs) use multiple tools, technologies and methods to take intrusions to a deeper and more dangerous level. In some cases, the intruders may never make their presence known. They simply pull information—everything from employee or customer data to intellectual property—to perpetuate attacks that monetize their efforts.

Secure Horizons

CIOs and other enterprise leaders must ultimately focus on strategies that rely on multiple tools, technologies and methods to address the problem on several fronts. This may include everything from reviewing privileges and reexamining authentication methods to analyzing coding practices and reviewing the way encryption is used for data at rest and in transit. It could also address everything from vendor relationships to coding practices.

For example, as organizations migrate to DevOps, it’s possible to use automated code scanning to detect vulnerabilities before software goes live. In addition, emerging cyber-security tools use artificial intelligence (AI), machine learning or deep learning, along with analytics, to detect unusual behavior and patterns. If an employee logs in at an unusual time from an unknown device or IP address, the system may require re-authentication.

However, TCS’ Logan also stresses the urgency of employee education and training. Many of today’s breaches are caused by inattentive employees, sometimes even those in the C-suite, who click a link and infect a system with malware, including ransomware. In other cases, employees circumvent policies because they interfere with their work, or they turn to shadow IT and rogue applications to complete work easier or faster.

“Ongoing employee education about phishing—and the use of anti-phishing campaigns that send test emails to users and then respond to clicks with just-in-time education—is an effective addition to employee security awareness efforts,” Logan says. Likewise, intelligence sharing services can help organizations identify new risks quickly.

In the end, Logan says that a simple mnemonic is useful for security transformation: ARM. This translates to assess, remediate and monitor. Best-practice organizations embed cyber-security into the foundation of day-to-day IT operations. They have robust backup and recovery systems in place to guard against ransomware and other problems. They handle basic blocking and tackling but also examine how more advanced tools, technologies and practices can boost protection.

To be sure, the road to security transformation is long and winding. “A world-class organization must excel at the basics of identity management, vulnerability management, configuration management, incident management, incident response, backup and recovery,” Logan explains.

Capgemini’s Deally adds: “From a CIO’s perspective, it’s essential to look at what are you doing from a business perspective and build security protections from there. The most important question—and the one to work backward from in every case—is, ‘How can I best mitigate risk?’

Cyber-Attacks Cost Almost Twice What You May Think

What do cyber-attacks have in common with hurricanes, tornados and earthquakes? All are realities in our world. No matter how common or uncommon they may be, failing to prepare for any of them will lead to costs that could be unbearable—or worse. These were the thoughts of Nikhil Taneja, MD Radware as he shared the company’s annual Global Application & Network Security Report 2016-17 that identifies major attack trends of 2016, outlines industry preparedness, and offers predictions for in 2017.

The report finds that 98% of Organizations Experienced Attacks in 2016, indicating that cyber-attacks became a way of life for nearly every organization in 2016. This trend will continue in 2017, predicts Radware.

While understanding some crucial aspects such as The threat landscape—who the attackers are, their motives and tools, what will be the potential impact on businesses, including associated costs of different cyber-attacks, how  a company’s preparedness level compares to other organizations etc, the report comes up with some of the key findings:

– IoT Botnets Open the 1TBps Floodgates- This exemplifies why preparing for “common” attacks is no longer enough. This event introduced sophisticated vectors, such as GRE floods and DNS water torture.

– Cyber-Ransom Proves Easiest, Most Lucrative Tool for Cybercriminals- Almost all ransom events have a different attack vector, technique or angle. There are hundreds of encrypting malware types, many of which were developed and discovered this year as part of the hype. Also, DDoS for ransom groups are professionals who leverage a set of network and application attacks to demonstrate their intentions and power.

– Cyber-Attacks Cost Almost Twice What You May Think- Most companies have not come up with a precise calculation of the losses associated with a cyber-attack. Those who have quantified the losses estimate the damage at nearly double the amount compared to those who estimate.

– Stateful Devices: #1 Point of Failure- Common IT devices, including firewalls, application delivery controllers and intrusion protection systems, now represent the greatest risk for an outage. Consequently, they require a dedicated attack mitigation solution to protect them.

Threat Landscape Trends

The report identifies top five trends that dominated 2016 threat landscape and will continue to haunt CISOs in the coming years. These include:

– Data Leakage + SLA Impact Are Top Concerns – Data leakage and service level impact often come together, with a DDoS attack serving as a smokescreen that distracts IT teams so data can be infiltrated.

– Mirai Rewrites the Rules- As the first IoT open-source botnet, Mirai is changing the rules of real-time mitigation and makes security automation a must. It isn’t just that IoT botnets can facilitate sophisticated L7 attack launches in high volumes. The fact that Mirai is open-source code means hackers can potentially mutate and customize it—resulting in an untold variety of new attack tools that can be detected only through intelligent automation.

– Non-Volumetric DoS: Alive and Kicking – Despite astonishing volumes, neither the number of victims nor the frequency of attacks has grown. Most non-volumetric DDoS attacks are in relatively lower volumes, with 70% below 100Mbps. Rate-based security solutions continue to fall short, requiring companies to rethink their security strategy and embrace more sophisticated solutions. Without those upgrades, there is a good chance an organization will experience, yet lack visibility into service degradation.

– Increased Attacks against Governmental Institutions- 2016 brought a new level of politically affiliated cyber protests. While the U.S. presidential election was in the spotlight, the media reported on a different breach almost weekly. These incidents happened across the globe, with regimes suffering from cyber-attacks due to alleged corruption or perceived injustices.

– SSL-Based Attacks Continue to Grow- Although 39% report suffering an SSL-based attack, only 25% confidently state they can mitigate it.

– DDoS Attacks Are Becoming Shorter- Burst attacks are increasing thanks to their effectiveness against most mitigation solutions.

Security Strategy Evolves Rather Slowly 

These trends and findings indicate that while hackers continue to develop new attack tools and techniques, 40% of organizations do not have an incident response plan in place. Seventy percent do not have cyber-insurance. And despite the prevalence of ransomware, only 7% keep Bitcoin on hand.

Another interesting finding of the study was three-fourths of companies do not employ hackers in their security teams, and 43% say they could not cope with an attack campaign lasting more than 24 hours.

“Combining statistical research and frontline experience, the Radware report identifies trends that can help educate the security community. It draws information from sources such as the information security industry survey, where this year, 598 individual respondents representing a wide variety of organizations around the world participated,” Taneja commented.

On average, responding organizations have annual revenue of USD $1.9 billion and about 3,000 employees. Ten percent are large organizations with at least USD 5 billion in annual revenue. Respondents represent more than 12 industries, with the largest number coming from the following: professional services and consulting (15%), high tech products and services (15%), banking and financial services (12%) and education (9%), the study notes.

New Mirai IoT variant launched 54-hour DDoS attack against a U.S. college

Researchers have spotted a new Mirai variant in the wild that is better at launching application layer attacks; other researchers spotted a new Cerber ransomware variant that can evade machine learning.

A new variant of the Mirai IoT malware was spotted in the wild when it launched a 54-hour DDoS attack against an unnamed U.S. college.

While the attack occurred on February 28, Imperva Incapsula is informing  the world about it today. The researchers believe it is a new variant of Mirai, one that is “more adept at launching application layer assaults.”

The average traffic flow was 30,000 requests per second (RPS) and peaked at about 37,000 RPS, which the DDoS mitigation firm said was the most it has seen out of any Mirai botnet so far. “In total, the attack generated over 2.8 billion requests.”

During the 54-hour DDoS attack on the college, researchers observed a pool of attacking devices normally associated with Mirai such as CCTV cameras, DVRs and routers. Attack traffic originated from 9,793 IPs worldwide, but 70% of the botnet traffic came from 10 countries.

The U.S. topped the list by having 18.4 percent of the botnet IPs. Israel was next with 11.3 percent, followed by Taiwan with 10.8 percent. The remaining seven countries of the top 10 were India with 8.7 percent, Turkey with 6 percent, Russia with 3.8 percent, Italy and Mexico both with 3.2 percent, Colombia with 3 percent and Bulgaria with 2.2 percent of the botnet traffic.

Other signature factors such as header order and header values also helped the researchers identify the attack as a Mirai-powered botnet, yet the DDoS bots hid behind different user-agents than the five hardcoded in the default Mirai version; it used 30 user-agent variants. Incapsula said, “This–and the size of the attack itself–led us to believe that we might be dealing with a new variant, which was modified to launch more elaborate application layer attacks.”

Less than a day after the 54-hour hour attack on the college ended, another was launched which lasted for an hour and half; during the second attack, the average traffic flow was 15,000 RPS.

90% of application layer attacks last less than six hours, Incapsula said, so “an attack of this duration stands in a league of its own.” The researchers said they “expect to see several more bursts before the offender(s) finally give up on their efforts.”

Cerber ransomware variant evades machine learning

Elsewhere, Trend Micro also has bad news in the form of a new Cerber ransomware variant. Cerber has “adopted a new technique to make itself harder to detect: it is now using a new loader that appears to be designed to evade detection by machine learning solutions.”

The newest Cerber variant is still being delivered via phishing emails, but those emails now include a link to Dropbox which downloads and self-extracts the payload. If the loader detects it is running in a virtual machine, in a sandbox, or if certain analysis tools or anti-virus are running, then the malware stops running.

Cerber stops, Trend Micro said, if it detects any of the following are running: msconfig, sandboxes, regedit, Task Manager, virtual machines, Wireshark, or if security products from the vendors 360, AVG, Bitdefender, Dr. Web, Kaspersky, Norton or Trend Micro are running.

Trend Micro explained:

Self-extracting files and simple, straightforward files could pose a problem for static machine learning file detection. All self-extracting files may look similar by structure, regardless of the content. Unpacked binaries with limited features may not look malicious either. In other words, the way Cerber is packaged could be said to be designed to evade machine learning file detection. For every new malware detection technique, an equivalent evasion technique is created out of necessity.

IoT DDoS Reaches Critical Mass

In the wake of the Mirai botnet activity that dominated the end of last year, the “DDoS of Things (DoT)”, where bad actors use IoT devices to build botnets which fuel colossal, volumetric DDoS attacks, has become a growing phenomenon. 

According to A10 Networks, the DoT is reaching critical mass—recent attacks have leveraged hundreds of thousands of IoT devices to attack everything from large service providers and enterprises to gaming services, media and entertainment companies. In its research, it uncovered that there are roughly 3,700 DDoS attacks per day, and the cost to an organization can range anywhere from $14,000 to $2.35 million per incident.

In all, almost three quarters of all global brands, organizations and companies (73%) have been victims of a DDoS attack. And, once a business is attacked, there’s an 82% chance they’ll be attacked again: A full 45% were attacked six or more times.

There were 67 countries targeted by DDoS attacks in Q3 2016 alone, with the top three being China (72.6%), the US (12.8%) and South Korea (6.3%). A10 found that 75% of today’s DDoS attacks target multiple vectors, with a 60/40 percentage split of DDoS attacks that target an organization’s application and network layers, respectively.

Meanwhile, DDoS-for-hire services are empowering low-level hackers with highly damaging network-layer bursts of 30 minutes or less. This relentless attack strategy systemically hurts corporations as colossal DDoS attacks have become the norm too; 300 Gbps used to be considered massive, but today, attacks often push past 1 Tbps thanks to the more than 200,000 infected IoT devices that have been used to build global botnets for hire.

No industry is immune: While 57% of global DDoS attacks target gaming companies, any business that performs online services is a target. Software and technology were targeted 26% of the time; financial services 5%; media and entertainment, 4%; internet and telecom, 4%; and education, 1%.

Security Company CloudFlare leaks sensitive customer information for tens of thousands of websites

cloudflare: Cloudflare Reverse Proxies are Dumping Uninitialized Memory

(It took every ounce of strength not to call this issue "cloudbleed")

Corpus distillation is a procedure we use to optimize the fuzzing we do by analyzing publicly available datasets. We've spoken a bit about this publicly in the past, for example:

https://security.googleblog.com/2011/08/fuzzing-at-scale.html


http://taviso.decsystem.org/making_software_dumber.pdf#page=11

On February 17th 2017, I was working on a corpus distillation project, when I encountered some data that didn't match what I had been expecting. It's not unusual to find garbage, corrupt data, mislabeled data or just crazy non-conforming data...but the format of the data this time was confusing enough that I spent some time trying to debug what had gone wrong, wondering if it was a bug in my code. In fact, the data was bizarre enough that some colleagues around the Project Zero office even got intrigued.

It became clear after a while we were looking at chunks of uninitialized memory interspersed with valid data. The program that this uninitialized data was coming from just happened to have the data I wanted in memory at the time. That solved the mystery, but some of the nearby memory had strings and objects that really seemed like they could be from a reverse proxy operated by cloudflare - a major cdn service.

A while later, we figured out how to reproduce the problem. It looked like that if an html page hosted behind cloudflare had a specific combination of unbalanced tags, the proxy would intersperse pages of uninitialized memory into the output (kinda like heartbleed, but cloudflare specific and worse for reasons I'll explain later). My working theory was that this was related to their "ScrapeShield" feature which parses and obfuscates html - but because reverse proxies are shared between customers, it would affect *all* Cloudflare customers.

We fetched a few live samples, and we observed encryption keys, cookies, passwords, chunks of POST data and even HTTPS requests for other major cloudflare-hosted sites from other users. Once we understood what we were seeing and the implications, we immediately stopped and contacted cloudflare security.

This situation was unusual, PII was actively being downloaded by crawlers and users during normal usage, they just didn't understand what they were seeing. Seconds mattered here, emails to support on a friday evening were not going to cut it. I don't have any cloudflare contacts, so reached out for an urgent contact on twitter, and quickly reached the right people.



After I explained the situation, cloudflare quickly reproduced the problem, told me they had convened an  incident and had an initial mitigation in place within an hour.

"You definitely got the right people. We have killed the affected services"

Bitfinex Targeted in “Severe” DDoS Attack Amid Bitcoin Price Surge

Prominent bitcoin exchange Bitfinex revealed it was struck by a significant DDoS attack late Tuesday night (UTC).  However, the denial of service attack was promptly mitigated, with minimal impact on operations.

The Hong Kong-based cryptocurrency exchange confirmed it was “under severe DDoS attack” on a social media post yesterday. The attack coincides with bitcoin prices reaching some of the highest prices set in its entire history, as bitcoin-seeking extortionists continue to attack the most straightforward target for demanding bitcoin ransoms.

Screen Shot 2017-02-22 at 13.07.32

The disruption impacted users, some of whom pointed to the crypto-exchange’s chosen DDoS protection service CloudFlare blocking API functions.

Screen Shot 2017-02-22 at 13.07.40

The exchange further confirmed that API performance took a hit.

The attacks began late Tuesday night as BitFinex began investigating the disruption at 21:34 UTC. To its credit, Bitfinex took measures to identify and block the DDoS attack in a 15-minuite monitoring period.

“We have taken steps to identify and block the attack. The system is returning to normal” the exchange confirmed soon after.

Information from its status page reveals that all services were back to normal, less than an hour after the attack caught attention.

Bitfinex has faced outages due to DDoS attacks in the past. In mid-2015, when the website was still in its “beta” phase, the website was completely knocked offline following a DDoS attack. The exchange had previously made headlines that year following a hack of its hot wallet. It is speculated that just about 0.5 percent of the exchange’s bitcoin holdings, approx. 1,400 BTC, was stolen during the hack. The hack pales in comparison to the infamous 2016 theft of nearly 120,000 bitcoins, approx. $65 million at the time, which promptly sent bitcoin price crashing after the exchange suspended trading.

In recent times, Bitfinex has become the dominant bitcoin exchange by daily trading volume globally.

Figures from CoinMarketCap reveal the Hong Kong-based exchange leading others by a significant distance.

Screen Shot 2017-02-22 at 13.08.28

Bitfinex also leads the pack in overall trading of cryptocurrencies including bitcoin, followed by Kraken.

Majority of DDoS Attacks in October-December 2016 Conducted From Germany, UK, US

According to reports, United States, the United Kingdom and Germany became the top three source countries for DDoS attacks in October-December 2016.

MOSCOW (Sputnik) – The United States, the United Kingdom and Germany became the top three source countries for DDoS attacks in October-December 2016, an Internet company dubbed Akamai said in report Wednesday, adding that the overall number of attacks in 2016 increased by 4 percent compared to previous year.

“The top three source countries for DDoS attacks were the U.S. (24%), the U.K. (10%), and Germany (7%). In the past year, China dominated the top 10 list of source countries. In Q4 2016, China dropped to the fourth position overall, with 6% of traffic,” the State of the Internet / Security Report said.

Russia became the fifth country in the list, with 4.4 percent of attacks.

“The average number of DDoS attacks remained steady this quarter [October-December 2016] at 30 per target, indicating that after the first attack, an organization has a high likelihood of experiencing another,” the report said.

The study notes that the number of IP addresses, used for DDoS attacks, significantly increased in the last quarter of 2016.

The report also provides data regarding attacks in January- September 2016, with China, the United States, Turkey and the United Kingdom being the top source countries for attacks.

What retailers need to know about cybersecurity

Annual global costs tied to destruction of data, intellectual property theft, lost productivity and fraud are on pace to reach $6 trillion by 2021. Here’s how retailers can avoid becoming a statistic.

Cybercrime is big business — and retailers are squarely in the crosshairs.

Cybercrime — the catch-all term applied to an ever-expanding range of digital assaults from malware to theft of personal data to distributed denial-of-service attacks (DDoS, i.e. coordinated traffic onslaughts on servers, systems or networks designed to make the target difficult or impossible for legitimate users to access) — is rapidly growing more common, more dangerous and more complex. Service interruptions from DDoS attacks alone surged 162% in 2016. Cybercrime is also growing more lucrative: Nearly 90% of all cyberattacks now involve financial or espionage motivations, according to the Verizon 2016 Data Breach Investigations Report. Corresponding annual global costs related to damage and destruction of data, intellectual property theft, lost productivity and fraud are on pace to grow from $3 trillion in 2015 to $6 trillion by 2021.

While the second half of 2016 brought to light three of the largest data breaches ever recorded (two raids on web platform Yahoo that impacted at least 1.5 billion accounts combined; the other affecting about 412 million accounts across social network Adult Friend Finder), retailers in fact experience the most cyberattacks of any industry sector — about three times as many as the previous top target, the financial industry — information and communications technology firm NPD Group reports. The list of victims is long and ignominious, and includes Target, Home Depot, Eddie Bauer and Vera Bradley.

The question isn’t if and when yet another retailer will fall victim in the weeks and months ahead, experts say, but simply where the wheel of misfortune will land next.

“You’ll never be able to put up perimeters and defenses to stop the behavior of malicious attackers. Organizations need to accept the fact that if they’re not breached today, they likely will be breached at some point in the point in the future,” Paul Truitt, vice president of cybersecurity services at managed network solutions firm SageNet, told Retail Dive. “Getting ahead of the criminal and stopping them before they do what they’re going to do is a losing battle. But acting quickly and having the processes in place to respond what it does happen is achievable, and if every organization had that in place, we could significantly shorten the average data breach notification and identification, and also create much less juicy targets for the bad guys.”

Threat assessment

Retailers are like catnip to cybercriminals because of the wealth of customer data stored on their networks. While hijacking credit card account data has long been the primary objective — about 42 million Target shoppers had their credit or debit information stolen when the retailer was breached in late 2013 — thieves are also keen to acquire personal data like names, mailing addresses, phone numbers and email addresses.

“There’s a lot of data around shopping habits and purchasing patterns now being stored by retailers — information they never had before,” Truitt said. “If you’re tying a loyalty program to a mobile payment program, those payment programs are bringing more sensitive data into the retail organization than in the past, and that’s what criminals are looking for.”

The threat isn’t lost on retailers. Fully 100% of retail executives surveyed for the 2016 BDO Retail RiskFactor Report cited data privacy and security breaches as major business risks, up from 55% in 2011 and 26% in 2007. But according to Truitt, relatively few retailers have advanced their cybersecurity efforts beyond implementing the basic safeguards necessary to meet payment card industry (PCI) security standards.

“[Cybersecurity] varies by retailer,” he said. “We still see a lot of retail organizations putting their eggs into the PCI basket. The feeling is that they’ve secured their organizations by meeting PCI compliance requirements, but in reality, the vectors of attack are outside what PCI mandates needs to be done. When you think about security programs focusing only on PCI at best, we’re going to see a lot of data continue to be exposed.”

The media fallout and brand damage associated with past merchant data breaches (not to mention the legal costs and governmental penalties, which can run into the millions) are driving retailer cybersecurity awareness and investment, says Robert Horn, associate director at insurance and risk management solutions provider Crystal & Co.

“Retailers have been forced to increase their cybersecurity because of the breaches we’ve had in the last several years. Your public perception takes a hit, there’s customer churn, and the fines and penalties are increasing,” Horn told Retail Dive. “Cybersecurity is getting much more attention from the C-suite. Before, just the IT director was involved. Now you’ve got legal, you’ve got corporate governance, you’ve got the CFOs and the CEOs wanting to know what’s going on.”

But knowing what’s going on is easier said than done, because cybercrime evolves with mind-boggling speed. What began two decades ago with relatively simple viruses and website attacks hatched by malcontents seeking internet notoriety has rapidly mutated into discrete, laser-targeted and highly sophisticated offensives masterminded by thieves, hackers and extortionists motivated by financial gain.

“There isn’t a single organization that can say they’re 100% secure,” Maarten Van Horenbeeck, vice president of security engineering at content delivery network Fastly, told Retail Dive. “But there are organizations that have the maturity and the smart people to say, ‘We understand what is happening, and we believe we know how to defend against it and how to protect our customer data.’”

Personnel and protection

Understanding what’s happening begins with identifying potential cracks in your armor. Verizon found that most attacks exploit known vulnerabilities that businesses failed to patch, despite software providers making patches available months or even years prior to the breach taking place. In fact, the top 10 known vulnerabilities account for about 85% of all successful exploits each year. Avoiding disaster also depends on recognizing the warning signs and criminal patterns: 95% of breaches and 86% of security incidents fall into nine established exploit patterns.

Building a more secure retail business begins with smart personnel decisions. “The single biggest thing an organization can do today is hire the right people. There are so many technologies out there,” Van Horenbeeck said. “It’s like putting together a puzzle of the correct pieces to make sure you’re defending yourself against attack. You need to hire the right people who understand that puzzle, and who know how to make the organization as safe as possible.”

Perhaps no retail security solution has generated more headlines and discussion than the fall 2015 shift from traditional “swipe-and-signature” credit and debit cards to chip-enabled EMV cards, a move designed in part to better protect consumers from escalating transaction fraud. While EMV (which takes its name from Europay, MasterCard and Visa, the three companies that created its chip-integrated standard) effectively blocks card cloning and other commonplace criminal tactics, its security innovations are limited to transactions where the physical card is present, meaning many cyberthieves are shifting their focus from brick-and-mortar stores to the web.

That means retailers dependent on e-commerce must embrace software solutions including end-to-end software encryption, a method of secure communication that prevents hackers, internet service providers or any other third party from accessing, stealing or damaging cardholder data or other information during its transfer from one system or device to another.

“Organizations that have made investments in EMV but did not invest in end-to-end encryption have a risk misperception,” said SageNet’s Truitt. “They believe they are secure, but they’ve only accomplished authentication of credit cards. They’ve accomplished nothing related to the security of the actual transaction. Many retailers that don’t have security teams internally, or that outsource their security fully and don’t have anyone with that knowledge in-house, has misinformed themselves about what EMV is doing. We’re going to see more organizations put fewer security controls in place and reduce some spend, because they think they have put the right security in place. But they’ve left themselves more exposed than they used to be.”

Beyond the basics, retailers should also consider adopting data loss prevention solutions to help monitor, manage and protect confidential data wherever it’s stored or used, as well as emerging tools like advanced behavioral authentication (methodologies that monitor headquarters and store employees’ attributes and behaviors to prevent imposters from accessing infrastructure and data), data-mining and visualization techniques, and security response automation.

There’s no time to waste. Experts anticipate cybercrime to continue to increase in the months to come, and warn that emerging technologies like the Internet of Things and advances in artificial intelligence present a multitude of new opportunities for attack. Only the strong will survive.

“It’s hard to predict what new threats will come about,” said Horn. “[Security] all comes down to putting resources into cybersecurity teams. A bad breach can put you out of business.”
