How can you prepare for a cyber attack?

Keeping your data secure is more important than ever, but it seems like there’s a new wide-scale data breach every other week. In this article, David Mytton discusses what developers can do to prepare for what’s fast becoming inevitable.

Cyber security isn’t something that can be ignored anymore or treated as a luxury concern: recent cyber attacks in the UK have shown that no one is immune. The stats are worrying – in 2016, two thirds of large businesses had a cyber attack or breach, according to Government research. Accenture paints a bleaker picture suggesting that two thirds of companies globally face these attacks weekly, or even daily.

According to the Government’s 2016 cyber security breaches survey, only a third of firms have cyber security policies in place and only 10% have an emergency plan. Given management isn’t handling the threat proactively, developers and operations specialists are increasingly having to take the initiative on matters of cybersecurity. This article covers some essential priorities developers should be aware of if they want their company to be prepared for attack.

Know your plan

There’s no predicting when a cyber attack might come, whether it be in the form of a DDoS, a virus, malware or phishing. It’s therefore important to be constantly vigilant, and prepared for incidents when they do occur.

Senior leadership in your company should be proactive when laying out a plan in the event of an attack or other breach, however this might not always be the case. No matter what your position is within your company, there are preemptive actions you can take on a regular basis to ensure that you’re adequately prepared.

If you’re in an Ops team, make sure you’re encouraging your team to test your backups regularly. There’s little use having backups if you’re unable to actually restore from them, as GitLab learned to their detriment earlier in the year.

Use simulations and practice runs to ensure that everyone on your team knows what they’re doing, and have a checklist in place for yourself and your colleagues to make sure that nothing gets missed. For example, a DDoS attack may begin with a monitoring alert to let you know your application is slow. Your checklist would start with the initial diagnostics to pinpoint the cause, but as soon as you discover it is a DDoS attack then the security response plan should take over.

If you happen to be on-call, make sure you’ve got all the tools you need to act promptly to handle the issue. This might involve letting your more senior colleagues know about the issue, as well as requesting appropriate assistance from your security vendors.

Communication is always one of the deciding factors in whether a crisis can be contained effectively. As a developer or operations specialist, it’s important to be vocal with your managers about any lack of clarity in your plan, and ensure that there are clear lines of communication and responsibility so that, when the worst does occur, you and your colleagues feel clear to jump into action quickly.

Remember your limits

It might sound obvious, but it’s worth remembering: in a cyber attack or catastrophic incident, there is only so much you yourself can do. Too many developers and operations staff fall prey to a culture of being ‘superheroes’, encouraged (often through beer and pizza) to stay as late as they can and work as long as possible on fixes to particular issues.

The truth is, humans make mistakes. Amazon’s recent AWS S3 outage is a good example: swathes of the internet were taken offline due to one typo. If you’re on-call while a cyber attack occurs there’s no denying you’re likely to work long hours at odd times of the day, and this can put a real strain on you, both mentally and physically. This strain can make it much harder for you to actually concentrate on what you’re doing, and no amount of careful contingency planning can compensate for that.

At Server Density we’re keenly aware that employee health and well being is critical to maintaining business infrastructure, especially in the event of a crisis. That’s why we support movements like HumanOps, which promote a wider awareness of the importance of employee health, from the importance of taking regular breaks to ergonomic keyboards. All too often people working in IT forget that the most business-critical hardware they look after isn’t servers or routers, it’s the health and well being of the people on the front lines looking after these systems.

Cyber attacks are stressful on everyone working in an organisation, and the IT teams take the brunt of the strain. However, with careful planning, clear lines of delegation and an appreciation of the importance of looking after each other’s health, developers and operations specialists should be able to weather the storm effectively and recover business assets effectively.

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?’

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.

Operator of DDoS protection service named as Mirai author

Krebs says he’s fingered author of epic IoT web assault code

The author of the massive distributed denial-of-service attack malware Mirai, which ropes infected routers and internet of things devices into remotely controlled armies, is a New Jersey man, according to journo Brian Krebs.

On his website this week, Krebs names a chap called Paras Jha, owner of a distributed denial-of-service (DDoS) attack mitigation company ProTraf Solutions, for the creation and dissemination of the Mirai software nasty.

Mirai is one of the worst DDoS botnets ever to grace the internet and is fingered for downing large chunks of the internet, including record-breaking attacks on Krebs’ own site.

Previous analyses have suggested the malware was penned by a person named “Anna-Senpai”.

Krebs builds a case to link Anna-Senpai to Jha and says that he, along with other players, built the Mirai code and used it to attack Minecraft servers to lure disgruntled customers.

He tells of how Jha contacted upstream providers to have command and control servers of rival IoT firms shut down, and how the hacker built malcode into his botnet that eliminated rival Qbot botnets.

Those upstream providers that ignored Jha’s requests were also subject to large DDoS attacks.

Mirai evolved from earlier incarnations of botnet code designed for DDoS attacks. In 2014 an earlier variant was used to launch DDoS attacks against Minecraft servers which can generate up to US$50,000 a month.

Krebs found that Jha lists the same skills on his LinkedIn page as on HackForums, a large marketplace where low level grey hat activities, cybercrime, and bragging takes place.

He details many other compelling links between Jha’s older identities he used online while learning to code, including ‘OG_Richard_Stallman’, and his recent aliases including Anna-Senpai. ®

DDoS attack and measures to Fight DDoS attack

White hats are in an ongoing battle with black hats for protecting the Internet from DDoS attacks. According to Abhor Network, more than 2000 daily DDoS attacks are observed worldwide.

In 2016, we saw the largest DDoS attack till date on Dyn (a DNS provider). During the attack, Dyn’s servers were loaded with more than  1.2 Tbps of data which crashed the company’s servers. This attack caused major websites like Twitter, Amazon, Reddit, and Netflix to go down. The attack was carried out using IoT devices infected by Mirai malware; which means the attacker might have used your routers, Smart TVs, mobiles, computers and IP cameras to do the DDoS attack.

Since the attackers have started using your Internet-connected devices to launch dangerous attacks (without your knowledge) against  Banks, Telecom, and Media (that speak against some political agendas), it is about time we(users) become aware of DDoS.

What is DDoS Attack?

DDoS is Distributed Denial of Service attack. In this attack, hackers use compromised systems (called botnets) to make online services unavailable to clients. During the attack, the attacker simply overfloods the service provider’s servers with fake traffics from multiple sources (botnets). This causes the servers to crash. Thus, the intended audience are deprived of the services.

In simple words, DDoS attack is like window shoppers swarming your business denying genuine customers from getting your service.

Symptoms of DDoS Attack:

According to Wikipedia, the United States Computer Emergency Readiness Team (US-CERT) has identified symptoms of a denial-of-service attack to include:

  • unusually slow network performance (opening files or accessing web sites)
  • unavailability of a particular website
  • inability to access any website
  • a dramatic increase in the number of spam emails received (this type of DoS attack is considered an e-mail bomb).

Additional symptoms may include:

  • disconnection of a wireless or wired internet connection
  • long-term denial of access to the web or any internet services.

Why is DDoS attack so dangerous?

  1. A large-scale attack can affect Internet connectivity of entire geographical regions.
  2. Anyone can buy a week of  DDoS attack at just $150 in the black market. Source: Trendmicro Research
  3. There can be millions of Botnets since many devices these days are connected to the Internet. This makes the attack more dangerous.
  4. There are more than 2000 attacks per day.
  5. Small businesses are an easy target because it is cheap and easy to attack services that don’t have DDoS countermeasures.

How to Fight DDoS attack:

  1. Be prepared by recognizing the symptoms of a DDoS attack.
  2. Get extra bandwidth for your website. This will give you time to fight the DDoS without your service going down.
  3. Monitor your website traffic regularly. Use Web Analytics tools.
  4. If you think you are under attack, contact your ISP or Host Provider.
  5. Use DDoS mitigation specialist companies if you can afford.

In conclusion, spread the words about DDoS attack to everyone you know who owns or wish to own a website. Also, prevent your devices from being compromised– I will write about it on next post. For now, let’s fight DDoS attacks together.

Russian telecom giant repels DDoS attacks on country’s 5 largest financial institutions

Russian telecom giant Rostelecom has thwarted DDoS-attacks on the five largest banks and financial institutions in the country, the company said in a statement.

All the attacks were recorded on December 5, 2016, the longest of them lasting for over two hours, Rostelecom said on Friday.

“The analysis of the attack sources carried out by Rostelecom specialists revealed that the traffic was generated from the home routers of users who are usually referred to IoT devices,” Muslim Medzhlumov, director of the Cybersecurity Center for Rostelecom, said in a statement, published on the company’s website.

“A distinctive feature of the attacks was that they were organized with the help of devices that support the CWMP Management Protocol (TR-069). A few weeks ago, a serious vulnerability was revealed in the implementation of this protocol on a number of devices from different manufacturers, which allows attackers [to] organize DDoS-attacks. At the beginning of last week, the largest German operator Deutsche Telecom was subjected to an attack on users’ home devices, as well as the Irish provider Eircom,” he explained.

The Russian Federal Security Service (FSB) reported on December 2 that it had received intelligence of foreign intelligence services preparing large-scale cyber-attacks in Russia in the period starting from December 5, 2016, aimed at destabilizing Russia’s financial system and the activities of a number of major Russian banks.

A RIA Novosti source close to the Central Bank reported that the Bank of Russia recorded several attacks on December 5 on the site of VTB Bank Group.

On Tuesday, Russian President Vladimir Putin signed into effect an updated doctrine on information security. It states that the limitless flow of information has a negative impact on international security, as it can be employed to pursue geopolitical and military goals, thus favoring organized crime, extremists and terrorists.

The doctrine notes that Russian government agencies, scientific centers, and military industries are being targeted by foreign intelligence services by means of electronic and cyber surveillance.

To counter threats and challenges in the information environment, Russia will build “strategic deterrents” and step up efforts to “prevent armed conflicts that stem from the use of IT.”

The doctrine also instructs government agencies to strengthen critical information infrastructure to protect against cyber and computer network attacks.

New DDoS attack method called BlackNurse lets hackers take down firewalls and servers from a single laptop

Security researchers have discovered a new attack technique that requires less effort to launch large-scale attacks.

A new DDoS attack method called BlackNurse has been discovered by security researchers, which allows hackers to launch large-scale attacks with less effort than is required for traditional DDoS attacks. BlackNurse also provides attackers with the ability to take down severs and firewalls with just a single laptop.

According to researchers at TDC SOC (Security Operations Centre of the Danish telecom operator TDC), BlackNurse leverages low-volume ICMP (Internet Control Message Protocol)-based attacks to launch attacks capable of overloading firewalls and shutting them down. BlackNurse targets vulnerable firewalls made by Cisco, PaloAlto and others, in a “ping flood attack” reminiscent of those popular in the 1990s.

TDC researchers said: “The BlackNurse attack attracted our attention, because in our anti-DDoS solution we experienced that even though traffic speed and packets per second were very low, this attack could keep our customers’ operations down. This even applied to customers with large internet uplinks and large enterprise firewalls in place. We had expected that professional firewall equipment would be able to handle the attack.

“Based on our test, we know that a reasonable sized laptop can produce approx a 180 Mbit/s DoS attack with these commands.”

Researchers at security firm Netresec, clarified how and why the new technique was dubbed BlackNurse, which according to the firm has caused “some confusion/amusement/discussion”. Netresec also cautioned about googling the term, which they claimed “might not be 100% safe-for-work, since you risk getting search results with inappropriate videos that have nothing to do with this attack”.

Netresec said: “The term ‘BlackNurse’, which has been used within the TDC SOC for some time to denote the ‘ICMP 3,3′ attack, is actually referring to the two guys at the SOC who noticed how surprisingly effective this attack was. One of these guys is a former blacksmith and the other a nurse, which was why a colleague of theirs jokingly came up with the name ‘BlackNurse’. However, although it was first intended as a joke, the team decided to call the attack ‘BlackNurse’ even when going public about it.”

How does BlackNurse work?

DDoS attacks ideally require a large volume of traffic to successfully cripple targets. Traditionally, large-scale attacks involve hoards of devices and numerous IP addresses working collectively to bombard a targeted server with massive volumes of traffic, in efforts to stop it from functioning. However, BlackNurse does not need an army of compromised devices; neither does it require high volumes of traffic. Instead, BlackNurse issues out low volume ICMP error messages to servers and firewalls, which can fairly easily overload the main processors, rendering them useless.

ESET security researcher Mark James told IBTimes UK: “BlackNurse uses ICMP flooding to achieve its goal. ICMP is also known as Ping and is predominantly used to test the connectivity between two computers. An ICMP (ping) echo request is sent from one machine and awaits an ICMP echo reply from the receiving machine.

“The time of the round trip is measured which would normally indicate how good the connection route is based on errors and or packet loss. If you take that same technology and send lots of requests without waiting for any replies, it’s possible to overload the destination server. It works two-fold, as often the receiving server will attempt to reply to the incoming requests and try to send replies thus increasing its activity and helping the initial attack. Also BlackNurse uses a different technique that is slower than traditional ICMP flood attacks utilising some firewall vulnerabilities or misconfiguration.”

Mitigation for such an attack is possible. “Disabling ICMP Type 3 Code 3 on the WAN interface can mitigate the attack quite easily,” the TDC researchers said. “This is the best mitigation we know of so far.”

Is government regulation the way to blunt DDoS attacks?

Government regulation is a sticky issue in any industry, perhaps even more in cyber security. Every time the government creates a rule or an obligation, goes the argument, it merely opens a hole to be exploited. Exhibit number one is the call for makers of any product with encryption to create a secure back door police and intelligence agencies can use to de-crypt possibly criminal communications.

Of course there’s no such thing as an absolutely secure  back door, so it will end up being used by criminals or nation states.

I raise this because last week security expert Bruce Schneier again raised the issue of whether governments should step in to help give more protection against distributed denial of service DDoS attacks.

It’s easy for attackers to build powerful DDoS botnets that leverage insecure Internet connected devices like consumer webcams, he argues, the most recent of which was the attack last month on U.S. domain name service provider Dyn Inc., which temporarily impaired the ability of a number of online businesses including Twitter.

It doesn’t matter, Schneier argues, if DDoS attacks are state-based or not. The fact the software is so easily available to their build a botnot or buy it as a service that can pour 1 TB and more of data at a target is the threat.

“The market can’t fix this because neither the buyer nor the seller cares,” he has written. One logical place to block DDoS attacks is on the Internet backbone, he says, but providers have no incentive to do it because “they don’t feel the pain when the attacks occur and they have no way of billing for the service when they provide it.”

So when the market can’t provide discipline, Schneier says, government should. He offers two suggestions:

–impose security regulations on manufacturers, forcing them to make their devices secure;

–impose liabilities on manufacturers of insecure Internet connected devices, allowing victims to sue them.

Either one of these would raise the cost of insecurity and give companies incentives to spend money making their devices secure, he argues.

I’m not sure. For one thing litigation is a long and expensive process. How do I sue a company headquartered in another country (say, China) that sells devices used by a person in a third country (say, Brazil) which is part of a botnet assembled by a person in another country (say, the U.S.) used to attack me in Canada?

There’s also the problem of defining secure. What can a manufacturer do if it forces creation a long password for a device, but users insist on insecure passwords (like “password123456879.”)

Still, we need to discuss short-term solutions because, as Schneier points out, with the huge number of insecure Internet connected devices out there the DDoS problem is only going to get worse.

Let us know what you think in the comments section below.

Massive DDoS Attacks Disable Internet Access Throughout Liberia

British security researcher Kevin Beaumont recently reported that a series of massive cyber attacks using the Mirai DDoS botnet periodically disabled all Internet access throughout the country of Liberia.

“Liberia has one Internet cable, installed in 2011, which provides a single point of failure for Internet access. … The attacks are extremely worrying because they suggest a Mirai operator who has enough capacity to seriously impact systems in a nation state,” Beaumont wrote.

An employee at a Liberian mobile service provider told Network Worldthat the attacks were hurting his business. “It’s killing our revenue,” he said. “Our business has been targeted frequently.”

Beaumont said it appears that the attacks, which targeted Liberian telecom operators who co-own the single Internet cable, were being used to test denial of service techniques.

Given the volume of traffic, more than 500 Gbps, Beaumont said it appears that the botnet is owned by the same actor who hit the managed DNS provider Dyn on October 21, disabling websites across the U.S.

Mikko Hypponen, chief research officer at F-Secure, told VICE News that those actors were probably… kids. “Kids who have the capability and don’t know what to do with it,” he said.

Flashpoint director of security research Allison Nixon agreed with that assessment, stating in a blog post, “The technical and social indicators of this attack align more closely with attacks from the Hackforums community than the other type of actors that may be involved, such as higher-tier criminal actors, hacktivisits, nation states, and terrorist groups.”

Still, NSFOCUS chief research intelligence analyst Stephen Gates told eSecurity Planet by email that attacks like these could have a real impact on tomorrow’s U.S. presidential election.

While U.S. polling machines aren’t connected to the Internet, Gates said, some voter identification systems may be. “In some states, the voter ID must be checked before a voter can proceed,” he said. “If those systems are connected to the Internet to gain access to a database of registered voters, and they were taken offline, then would-be voters could not be verified.”

“What that would mean to the election process is anyone’s guess,” Gates added.

According to Nexusguard’s Q3 2016 DDoS Threat Report, the number of reflection-based DDoS attacks fell more than 40 percent during the third quarter of the year, while IoT-based botnets reached unprecedented speeds. The U.S. saw the most attack events in the third quarter, followed by China, Russia and the United Kingdom.

“Few service providers can sustain the level of malicious traffic we saw in Q3 from IoT botnets, so these DDoS outages are causing companies to completely rethink their cybersecurity strategies,” Nexusguard chief scientist Terrence Gareau said in a statement.

“Hackers’ preferences for botnets over reflection attacks are typical of cyclical behavior, where attackers will switch to methods that have fallen out of popularity to test security teams with unexpected vectors,” Gareau added.

The Dyn DDOS Attack And The Changing Balance Of Online Cyber Power

As the denial of service (DDOS) attack against Dyn shook the internet a little over a week ago, it brought to the public forefront the changing dynamics of power in the online world. In the kinetic world of the past, the nation state equivalent was all-powerful, since it alone could raise the funds necessary to support the massive military and police forces necessary to command societies. In the online world, however, the “armies” being commanded are increasingly used against their will, massive networks of infected drone machines formed into botnets. The cost of acquiring, powering, cooling, connecting and operating these virtual soldiers are borne by private individuals and corporations, with criminal enterprises able to co-opt them into massive attack botnets. What does this suggest is in store for the future of the online world?

The notion of using large botnets to launch globally distributed DDOS attacks is by no means a new concept and in fact has become a hallmark of the modern web. Indeed, I remember as a freshman in college 16 years ago seeing a new Linux server installed where I worked one morning and seeing the same machine being carted off by the security staff that afternoon after it had been hacked and converted into a botnet drone just a few hours after being plugged in. What makes the attack against Dyn so interesting is the scale at which it occurred and its reliance on compromised Internet of Things devices, including DVRs and webcams, allowing it to command a vastly larger and more distributed range of IP addresses than typical attacks. Making the attack even more interesting is the fact that it appears to have relied on open sourced attack software that makes it possible for even basic script kiddies to launch incredibly powerful attacks with little knowledge of the underlying processes.

This suggests an immense rebalancing in the digital era in which anyone anywhere in the world, all the way down to a skilled teenager in his or her parent’s basement in a rural village somewhere in a remote corner of the world, can take down some of the web’s most visible companies and wreak havoc on the online world. That preliminary assessments suggest that the attack was carried out by private actors rather than a nation state only reinforces this shift in online power.

 Warfare as a whole is shifting, with conflict transforming from nations attacking nations in clearly defined and declared geographic battlespaces to ephemeral flagless organizations waging endless global irregular warfare. In the cyber domain, as the battleground of the future increasingly places individuals and corporations in the cross hairs, this raises the fascinating question of how they can protect themselves?

In particular, the attack against Dyn largely mirrored an attack against Brian Krebs’ Krebs on Security blog last month, which raises the specter of criminals and nations being able to increasingly silence their critics, extort businesses and wreak havoc on the online world, perhaps even at pivotal moments like during an election day.

In the physical world, the nation state offers protection over the physical assets of companies operating in its territories, with military and police forces ensuring the sanctity of warehouses, office buildings and other tangible assets. However, in the digital world, state hackers from one country can easily compromise and knock offline the ecommerce sites of companies in other nations or leak their most vital secrets to the world.

In the case of Brian Krebs’ site, his story thankfully has a happy ending, in which Alphabet’s Jigsaw (formerly Google Ideas) took over hostingof his site under their Project Shield program. Project Shield leverages Google’s massive global infrastructure to provide free hosting for journalistic sites under sustained digital attack, protecting them from repressive governments and criminal enterprises attempting to silence their online voices.

Looking to the future, what options do companies have to protect themselves in an increasingly hostile digital world? Programs such as the Project on Active Defense by George Washington University’s Center for Cyber & Homeland Security are exploring the gray space of proactive countering and highly active response to cyberattacks. For example, what legal and ethical rights does a company have to try and stop an incoming cyberattack? Can it “hack back” and disable key command and control machines in a botnet or take other active approaches to disrupt the incoming traffic? What happens if a company remotely hacks into a control machine to disable it and it turns out it is an infected internet-connected oven in someone’s house and in the process of disabling it, the oven malfunctions and turns to maximum heat and eventually catches fire and burns the house down? Is the company responsible for the damage and potential loss of life? What legal responsibilities and liabilities do device manufacturers have to develop a more secure Internet of Things? If a company in 2016 still sells devices with default administrative passwords and well-known vulnerabilities that make them easy prey for botnets, should the companies bear the same burden as any other consumer safety issue? As over-the-air remote security updates become more common, should legislation be passed to require all consumer devices have the ability to be remotely updated with security patches?

As the modern web celebrates more than 20 years of existence, somewhere over those last two decades the web has gone from a utopia of sharing and construction of a brighter future to a dystopia of destruction and unbridled censorship. Will the web grow up and mature to a brighter security future or will it descend into chaos with internet users fleeing to a few walled gardens like Facebook that become the “safe” version of the web? Only time will tell.
