The current state of the cyber security industry is troubling to say the least, with 2016 experiencing a greater number of successful, more vicious cyber attacks than ever before The past few months have summed up the current state of the cyber security industry. In a matter of days at the end of November the European Commission was brought offline by a distributed denial-of-service (DDoS) attack, San Francisco’s Municipal Railway was held to ransom by ransomware in a system-wide attack and it was revealed that in September the Japanese Defence Ministry and Self-Defence Forces were hacked, which may have compromised Japan’s internal military network. It seems almost farcical, and from these recent examples it is evident that critical infrastructure is totally unprepared for an attack and will continue to be severely vulnerable at the beginning of 2017. It is not just the public sector that is suffering, with private organisations facing daily hacking attacks despite serious investment in cyber security strategies. The problem is inherently twofold. The first is that cyber criminals and their tactics are constantly evolving, becoming more overwhelming and hard to detect by the day, it seems. The ferocity of cyber attacks was illustrated last year by the Mirai botnet n(or Dyn) attacks that overran a number of systems using corrupted Internet of Things (IoT) devices. When the malicious code was first published online in October, it gave a suspected group of teenagers the ability to shut down the likes of Twitter and Spotify. In the preceding month, Liberia’s internet was taken offline using the same code. Improving the security of IoT devices will be crucial during 2017. This is where the most devastating cyber attacks will originate. Source: http://www.information-age.com/get-ready-cyber-war-123464202/

Arbor Networks has released its 12th Annual Worldwide Infrastructure Security Report (WISR). The report covers a range of issues from threat detection and incident response to managed services, staffing and budgets. But the main focus is on the operational challenges internet operators face daily from network-based threats and the strategies adopted to address and mitigate them. The largest distributed denial-of-service (DDoS) attack reported this year was 800 Gbps, a 60% increase over 2015’s largest attack of 500 Gbps. According to Arbor, DDoS attacks are not only getting larger, but they are also becoming more frequent and complex. Darren Anstee, chief security technologist with Arbor Networks, says survey respondents have grown accustomed to a constantly evolving threat environment with steady increases in attack size and complexity over the past decade. “However, IoT botnets are a game changer because of the numbers involved – there are billions of these devices deployed and they are being easily weaponised to launch massive attacks,” he says. “Increasing concern over the threat environment is reflected in the survey results, which show significant improvements in the deployment of best practice technologies and response processes. The report also found that the emergence of botnets that exploit inherent security weaknesses in IoT devices and the release of the Mirai botnet source code have increased attacker ability to launch extremely large attacks. According to the company, the massive growth in attack size has been driven by increased attack activity on all reflection/amplification protocols, and by the weaponisation of IoT devices and the emergence of IoT botnets. Because of this, Arbor say the consequences of DDoD attacks are becoming clear – DDoS attacks they have successfully made many leading web properties unreachable – costing thousands, sometimes millions, of dollars in revenue. However, the company does point out that this year’s survey results indicate a better understanding of the brand damage and operational expense of successful DDoS attacks.

Global concern over distributed denial-of-service attacks
“In principle, most of the denial-of-service attacks we see have no solution,” a security expert, Peter Neumann of SRI International, told the New York Times at the time. “The generic problem is basically unsolvable.” It still is. Twenty years on, DDoS attacks have increased exponentially in size, and vast swathes of the internet remain vulnerable. Experts say the proliferation of new but vulnerable connected devices, such as thermostats and security cameras, as well as the architecture of the internet itself, mean DDoS attacks will be with us for the foreseeable future. And rather than a mere annoyance that takes your favorite websites offline, they are starting to become a serious threat. According to Arbor Networks, an internet monitoring company that also sells DDoS protection, the volume of global DDoS attacks has grown by more than 30 times between 2011 and 2014. The attacks are also getting more intense. A string of them in September and October, which set records in terms of the volume of traffic (in gigabits per second, or Gbps) in each attack, proved that DDoS can overwhelm the internet’s best defenses. Among those they took down or threatened were a hosting service, a domain-name services provider (whose clients, including Twitter and Spotify, thus became inaccessible across entire regions of the US), a major content-delivery network, and the internet’s best-known blogger on security matters, Brian Krebs. These are the most powerful DDoS attacks each year, by Arbor Networks’ count. The September and October attacks are thought to have been carried out using Mirai, a piece of malware that allows hackers to hijack internet-connected devices such as security cameras. These are often sold with weak default passwords that their users don’t bother (or know how) to change. Mirai tracks them down, takes them over, and incorporates them into a “botnet” that launches DDoS attacks as well as finding and infecting other devices. Botnets aren’t new, but Mirai takes them to a new level, argues a recent paper (pdf) from the Institute of Critical Infrastructure Technology (ICIT), a research group. It’s a “development platform” for hackers to customize, the researchers say; the code was made public on a hacker forum, and people are free to innovate and build on it. In the past couple of months it’s thought to have been used to cripple the heating systems of two residential buildings in Finland and the online services of several Russian banks. The researchers speculate that hackers could tailor Mirai to do far bigger damage, such as bringing down a power grid. In September, security expert Bruce Schneier pointed to evidence that a large state actor—China or Russia, most likely—has been testing for weak points in companies that run critical parts of American internet infrastructure. It’s not outlandish to imagine that in the future, DDoS attacks powered by something like Mirai, harnessing the vast quantity of weakly secured internet-connected gadgets, could become part of a new kind of warfare. At the moment, the main defense against a DDoS attack is sheer brute force. This is what hosting companies offer. If a client suffers a DDoS attack, the hosting provider simply assigns more servers to soak up the flood of traffic. But as the latest attacks have shown, the power of botnets is simply growing too fast for even the biggest providers to defend against. There is a fix that would prevent a common type of DDoS attack—a “reflection” attack. This is where a hacker sends messages out to a botnet that seem to come from the target’s IP address (like sending an email with a fake reply-to address), causing the botnet to attack that target. The proposed fix, a security standard known as BCP38, which would make such fake return addressing impossible, has been available for 16 years. If all the ISPs on the internet implemented BCP38 on their routers, the most powerful DDoS attacks would be far more difficult to launch. But the sheer number of networks and ISPs on the internet makes this idea wishful thinking, says Steve Uhlig, of London’s Queen Mary University, who specializes in the internet’s routing protocols.”Remember that the internet is made of more than 50,000 networks,” he says. If the most important and influential networks implement the fix, but the countless smaller operators don’t, DDoS attacks can continue to exploit spoofing. “Larger networks in the [internet core] can and do filter,” he says, “But they reduce the attacks by only a limited amount.” The internet’s decentralized design is what gives it its strength. But it’s also the source of what is rapidly becoming its biggest weakness. Source: http://qz.com/860630/ddos-attacks-have-gone-from-a-minor-nuisance-to-a-possible-new-form-of-global-warfare/

DDoS attacks have gone from a minor nuisance to a possible new form of global warfare
The developers of this new botnet are inspired by Mirai success. In a blog post by CloudFlare, it has been revealed that the US West Coast is likely to become the target of yet another huge DDoS attack but this time it will be conducted with a different botnet than Mirai that was using during Dyn DNS attack which forced sites like Twitter, Amazon, PayPal etc to go offline for hours. The content delivery network states in the blog post that the company has been observing the overflow of traffic from about two weeks. It seems to be coming from a single source. Seemingly, someone was firstly testing their abilities with a 9-to-5 attack schedule and then the attack pattern was shifted to 24 hours. This new botnet is either equal or superior to the Mirai botnet. After observing the heavy attack traffic that literally peaked at 172MBPS, which means about a million data packets per second or 400 gigabits per second, CloudFlare concluded that the botnet was being turned on and off by some person who was busy with a 9-to-5 job. In the blog post, CloudFare wrote: “The attack started at 1830 UTC and lasted non-stop for almost exactly 8.5 hours, stopping at 0300 UTC. It felt as if an attacker ‘worked’ a day and then went home.” For about a whole week, the same attacker was observed to be sending data packets in huge proportions every day. Then the schedule was abruptly changed since the attacker was working on a 24-hour basis. This hints at the fact that the attacking mechanism was taken over by another, much-organized group. It is worth noting that the attack traffic wasn’t launched via Mirai botnet; the attackers are using a different kind of software with different methods like “”very large L3/L4 floods aimed at the TCP protocol.” The company also noted that the attacks are now focused on locations that are smaller and fall within the jurisdiction of the US West Coast. The revelation arrived soon after the special cyber-security commission of the White House issued recommendations and delivered the paper to the president. In the recommendations, it was urged that effective actions are required to mitigate and/or eliminate threats involving botnets. The report issued by the White House’s Commission on Enhancing National Cyber-security basically highlights the vulnerable nature of cyber-security nowadays with the emergence of sophisticated DDoS attacks methods like Mirai botnet that has been causing havoc lately. The 100-page long report contained recommendations regarding how the US government should tackle this issue. The bottom line was that the issue was much severe than it seems on paper and there is a lot needed to be done as soon as possible or else the situation will go out of hands. The report has identified six imperatives and there are 16 recommendations along with 53 Action Items aimed at countering the threat. The crux of the report and the commission’s research is that the US government and the private sector must collaborate and work closely to devise ways for handling cyber-security related issues and vulnerabilities along with developing programs for handling such problems in future.

New Botnet is Attacking the US West Coast with Huge DDoS Attacks
Dubai: After a slight downturn in the second quarter of this year, the average number of Distributed Denial of Service (DDoS) attacks increased to an average of 30 attacks per target. Fact Box description starts here Fact Box description ends here This reflects that once an organisation has been attacked, there is a high probability of additional attacks, a cyber security expert said. Fact Box description starts here Fact Box description ends here “Cybercriminals have found new attack channels to disable resources as the total DDoS attacks increased by 71 per cent year over year in the third quarter. During the third quarter, we mitigated a total of 4,556 DDoS attacks, an eight per cent decrease from second quarter,” Dave Lewis, Global Security Advocate at Akamai Technologies, told Gulf News. Fact Box description starts here Fact Box description ends here DDoS attack means an attacker sends too much traffic to a server beyond it can handle and the server goes offline. Fact Box description starts here Fact Box description ends here “We are seeing more and more of short-based attacks with limited bandwidth and consequence. There were 19 mega attacks mitigated during the quarter that peaked at more than 100Gbps, matching the first quarter high point,” he said. It’s interesting that while the overall number of attacks fell by eight per cent quarter over quarter, he said the number of large attacks, as well as the size of the biggest attacks, grew significantly. Fact Box description starts here Fact Box description ends here In contrast to previous quarters, when reflection attacks generated the traffic in the largest attacks, a single family of botnets, Mirai, accounted for the traffic during these recent attacks. Rather than using reflectors, he said that Mirai uses compromised internet of Things systems and generates traffic directly from those nodes. Fact Box description starts here Fact Box description ends here The Mirai botnet was a source of the largest attacks Akamai mitigated to date, an attack that peaked at Fact Box description starts here Fact Box description ends here 623Gbps. Mirai did not come out of nowhere. What makes Mirai truly exceptional is its use of IoT devices and several capabilities that aren’t often seen in botnets. Fact Box description starts here Fact Box description ends here The two largest DDoS attacks this quarter, both leveraging the Mirai botnet, were the biggest observed by Akamai to-date — recorded at 623Gbps and 555Gbps. Fact Box description starts here Fact Box description ends here “Attackers are generally not looking for vulnerable systems in a specific location, they are scanning the entire internet for vulnerable systems. The Mirai botnet is especially noisy and aggressive while scanning for vulnerable systems,” he said. Fact Box description starts here Fact Box description ends here He said that some clients are almost always under attack. The top target organisations saw three to five attacks every day of the quarter. However, without defences in place, these attacks could have a “substantial cumulative effect” on an organisation’s’ reputation. Fact Box description starts here Fact Box description ends here “It is becoming easier for hackers to launch attacks on commoditised platforms for lesser price than a coffee cup. The internet of Things are very good at what they are good at but security is often left out. We see these devices like DVRs with default credentials with an insecure protocol,” he said. Fact Box description starts here Fact Box description ends here According to Akamai Technologies’ Third Quarter, 2016 State of the internet/Security Report, majority of web application attacks continued to take place over http (68 per cent) as opposed to https (32 per cent), which could afford attackers some modicum of protection by encrypting traffic in transit. Fact Box description starts here Fact Box description ends here The US remained the top target for web application attacks as many organisations are headquartered in the US, with the resultant infrastructure also hosted in-country, it is expected that the US will continue to be the top target for some time. Fact Box description starts here Fact Box description ends here Brazil, the top country of origin for all web application attacks in the second quarter, experienced a 79 per cent decrease in attacks this quarter. The United States (20 per cent) and Netherlands (18 per cent) were the countries with the most web application attacks.

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 Internet of Things: blessing or curse? That depends on how much you value your privacy against the ability of your fridge to order fresh milk. Either way, we are now more vulnerable to hackers. Here’s how. I won’t even attempt to answer the question in my opening gambit. Who can say for sure this early whether the Internet of Things is a blessing or a curse (aside from the fact that clichés are always a curse). For one this is something we all have to decide for ourselves – hopefully, after diligent public debate. We all have to decide what privacy is in the digital era, and whether it’s important to us. We may support more stringent data protection laws, even a global bill of rights. Or we may find ourselves in the “post-privacy” camp and not really care. It also depends on how highly we value our digital security. Unbeknownst to us Take the DDoS (distributed denial-of-service) attack that brought down a litany of popular websites last Friday (21.10.2016). The affected websites included Esty, Github, HBO Now, PayPal, Pinterest, Playstation Network, Recode, Reddit, Spotify, Twitter, Netflix, Yammer, and Yelp. Your fridge, your mom’s webcam, computers at the local school, and a kid’s doll may have all taken part – without your even knowing it. Someone, somewhere launched a piece of malware called Mirai. We’ve known about Mirai – so something was in the wind. And DDoS attacks themselves have been around for ages. Mirai searched for poorly-protected, networked devices. That is, household devices that had little or no password protection. Reports suggest these included DVRs and webcams made by a Chinese company called Hangzhou XiongMai, which has since issued a recall on its webcams in the US. Mirai turned the connected devices into its slaves. They then launched the DDoS attack on servers run by Dyn, a so-called DNS host, and home to all those websites. Usually, when you call up a website, your “request” goes via one of these servers. But when the servers are overloaded with bad requests consisting of incomplete data, or they are bombarded with more requests than they can handle, they basically freak out. And no one is served. That’s what happened on Friday. Your fridge, webcam, toy truck and thousands more emitted a coordinated attack of useless information, bringing down some of the world’s most popular websites. The rest is history… Friday’s Mirai attack may well be history now, but it’s one which will surely repeat itself. Many, many times. The question is, where will it all end? If it’s only Netflix and Spotify you can’t access, you may really not care. Certainly if they are back up and running within a few hours. But what if it’s a vital government website, online access to your local hospital, the police, or the energy grid… and what if the attack lasts for days, weeks even? This is what we mean when we talk about cybersecurity. Private, commercial concerns, even dating apps, shouldn’t come into it. And yet what we do – and allow – at a private level can have a momumental impact on society. We may think it’s just the fridge ordering our milk or Barbie chatting to our kids. But we forget that every electronic device these days – especially those connected to the network – is vulnerable to hackers. And the Mirai attack has reminded us they can all be reprogrammed to do whatever the hackers want.
