Alleged UK Bank Hacker Extradited From Germany

U.K. officials have extradited the man who allegedly masterminded a cyberattack earlier this year that impacted two of England’s biggest banks. They have accused 29-year-old Daniel Kaye, who was found in Germany, of using an infected computer network to damage and blackmail both Barclays and Lloyds Banking Group, The Financial Times  reported. Following the cyberattack, Lloyds found its digital services crippled on and off for over 48 hours in January 2017, preventing some customers from being able to check their bank balances or send out payments via the network. The assault was a distributed “denial of service” (DDoS) attack, which overwhelms a firm’s website so its services don’t operate properly. The same month, Barclays fought off their own cyberattack, according to the National Crime Agency. These cybercrime attacks occurred just months following a high-profile cyberattack against Tesco Bank that caused 9,000 people to have their money stolen from accounts. HSBC also saw an attack against its personal banking website and mobile app in 2016, causing thousands of customers to be locked out of their accounts. “The investigation leading to these charges was complex and crossed borders,” said Luke Wyllie, the National Crime Agency’s senior operations manager. “Our cybercrime officers have analyzed reams of data on the way. Cybercrime is not victimless, and we are determined to bring suspects before the courts,” the  Financial Times reported. Daniel Kaye is also being accused of operating a cyberattack against Liberia’s largest internet provider, Lonestar MTN. Kaye is scheduled to appear in the U.K.’s Westminster Magistrates Court on Aug. 31. “In January, we were the target of a substantial distributed denial of service (DDoS) attack,” Lloyds Banking Group said in remarks according to news by the  Financial Times . “This was successfully defended but resulted in intermittent and temporary service issues for some customers. There was no attempt to access the bank’s systems and no customer details or accounts were compromised.” Source: http://www.pymnts.com/news/security-and-risk/2017/cybercriminal-daniel-kaye-extradited-following-ddos-cyberattacks/

Google pulls 300 Android apps used for DDoS attacks

A number of security researchers teamed up to fight the WireX botnet. If a random storage manager or video player you downloaded recently has disappeared from your Android device, don’t worry: it might have been for your own good. Google has removed 300 apps from the Play store, which were apparently merely masquerading as legitimate applications. In truth, they were made to hi-jack your phone so it can be used as part of a botnet’s distributed denial of service (DDoS) attacks. WireX, as the botnet is called, pummeled several content providers and delivery networks with traffic from the devices it hi-jacked on August 17th, though it’s been active since around August 2nd. In some cases, it also acted as a ransomware, demanding money from its victim. It was content delivery network Akamai that discovered its existence following an assault on one of its clients. The company then got together with Google and several security researchers from rival companies like Cloudflare, Flashpoint, Oracle + Dyn, RiskIQ, Team Cymru and other organizations to solve the issue. Upon learning that the Play Store is inundated with hundreds of fake WireX apps hiding behind the guise of innocuous programs like storage managers and ringtones, the big G did its part and blocked them all. Here are a few samples of infected apps: In a statement, Mountain View said it’s now also in the process of removing applications from affected devices. It’s unclear how long that would take, though, since based on the team’s research, WireX compromised over 70,000 devices from over 100 countries.

Critical infrastructure not ready for DDoS attacks: FOI data report

The UK’s critical infrastructure is vulnerable to DDoS attacks due to failure to carry out basic security defence work –  39 percent of respondents to a recent survey had not completed the government’s ’10 Steps to Cyber Security’ programme, which was first issued in 2012. New data was obtained by Corero Network Security under the Freedom of Information Act surveying 338 critical infrastructure organisations in the UK, including fire and rescue services, police forces, ambulance trusts, NHS trusts, energy suppliers and transport organisations; it also showed  that 42 percent of NHS Trusts had not completed the programme. More than half  (51 percent) of these critical infrastructure organisations were described by Corero as ignoring the risk of short, stealth DDoS attacks on their networks – which typically account for around 90 percent of DDoS attacks and are used by attackers to plant malware or ransomware, or engage in data theft.  Corero reports that these stealth attacks are typically  less than 30 minutes in duration, and 98 percent of those stopped by the company were less than 10Gbps in volume, hence they often go unnoticed by security staff, but are frequently used by attackers in their efforts to target, map and infiltrate a network. In a statement issued today, Sean Newman, director of product panagement at  Corero, comments: “Cyber-attacks against national infrastructure have the potential to inflict significant, real-life disruption and prevent access to critical services that are vital to the functioning of our economy and society. These findings suggest that many such organisations are not as cyber resilient as they should be, in the face of growing and sophisticated cyber threats.” Newman adds, “ By not detecting and investigating these short, surgical, DDoS attacks on their networks, infrastructure organisations could also be leaving their doors wide-open for malware or ransomware attacks, data theft or more serious cyber attacks.” It was also pointed out that in the event of a breach, these organisations could be liable for fines of up to £17 million, or four percent of global turnover, under the UK government’s proposals to implement the EU’s Network and Information Systems (NIS) directive, from May 2018. In an email to SC, David Emm, principal security researcher, Kaspersky Lab observed, “The world isn’t ready for cyber -threats against critical infrastructure – but criminals are clearly ready and able to launch attacks on these facilities. We’ve seen attempts on power grids, oil refineries, steel plants, financial infrastructure, seaports and hospitals – and these are cases where organisations have spotted attacks and acknowledged them. However, many more companies do neither, and the lack of reporting these incidents hampers risk assessment and response to the threat.” Edgard Capdevielle, CEO of Nozomi Networks, also emailed SC to comment: “This report emphasises the impact of DDoS attacks and how they are often used as a cover to distract security teams while infecting systems with malware or stealing data. Such initiatives are often the first step in “low and slow” attacks that provide the perpetrators with the information and access they need to carry out system disruptions. Examples of this are the Ukraine power outages of 2015 and 2016, both of which involved cyber-attacks which persisted for many months before culminating in shutdowns. “In light of this information, CNI organisations should give a high priority to re-assessing their cyber-security programmes, evaluate where they are in relation to government recommendations, and inform themselves about current technologies available for protection….The right approach is to both shore up defenses and be able to quickly respond when attacks do occur.” Previously, when talking about the new UK legislation targetting CNI, Eldon Sprickerhoff, founder and chief security strategist at eSentire commented in an email to SC, “Although cyber-security regulations will require significant effort for the companies that are affected, this new legislation by the UK government demonstrates that they understand the severity of cyber-threats in today’s digital world and the destruction they can cause, if undeterred.  Even if you’re not a CNI, cyber-threats should concern you. With cyber-criminals constantly adjusting their tactics, it is imperative that companies never stop defending themselves by constantly improving and expanding their cyber-security practices. Managed detection and response and incident response planning are common ways companies can stay ahead of their attackers.” Sprickerhoff recommended the same measures be taken by CNI organisations to improve cyber-security as for other enterprises, namely: Encryption – store sensitive data that is only readable with a digital key Integrity checks – regularly check for any changes to system files Network monitoring – use tools to help you detect for suspicious behaviour Penetration testing – conduct controlled cyber-attacks on systems to test their defences and identify vulnerabilities Education – train your employees in cyber-security awareness and tightly manage access to any confidential information  Source: https://www.scmagazineuk.com/critical-infrastructure-not-ready-for-ddos-attacks-foi-data-report/article/684838/

Hackers Use Thousands Of Infected Android Devices In DDoS Attacks

Hundreds of thousands of home routers, IP cameras and other internet-of-things devices have been infected with malware over the past year and have been used to launch some of the largest distributed denial-of-service (DDoS) attacks ever recorded. Attackers are now doing the same with Android devices, with the help of malicious applications hosted on Google Play and other third-party app stores. A joint investigation by the security teams from Akamai, Cloudflare, Flashpoint, Google, RiskIQ and Team Cymru has led to the discovery of a large botnet made up of over 100,000 Android devices located in more than 100 countries. The investigation was launched in response to large DDoS attacks that have hit several content providers and content delivery networks over the past few weeks. The goal behind DDoS attacks is to flood servers with bogus traffic in order to use up their available internet bandwidth or their CPU and RAM resources so they can no longer serve requests from legitimate users. Servers are typically configured to handle a certain number of concurrent connections based on the estimated number of visitors that they’re expected to receive. Load balancers, firewalls and other anti-DDoS technologies are used to limit the negative impact of any sudden traffic spikes, but with enough firepower, attackers can disrupt even the most well-protected networks. This particular Android botnet, which has been dubbed WireX, was used to send tens of thousands of HTTP requests that were meant to resemble those coming from legitimate browsers. The researchers were able to establish a pattern to the User-Agent string reported by the rogue clients and traced them back to malicious Android applications. Some of the applications were available in third-party app stores that came pre-installed on devices, but around 300 of them were hosted on Google Play. “Many of the identified applications fell into the categories of media/video players, ringtones or tools such as storage managers and app stores with additional hidden features that were not readily apparent to the end users that were infected,” the researchers said in a report. Most of the rogue applications requested device administrator permissions during installation, which allowed them to launch a background service and participate in DDoS attacks even when the applications themselves were not actively used or when the devices were locked. Google has removed the malicious applications from Google Play and started to remotely remove them from affected devices as well. Furthermore, the Play Protect feature which runs locally on Android devices prevents these apps from being reinstalled, the researchers said. Some antivirus products detect the malicious applications as an “Android Clicker” Trojan which might suggest that the botnet’s original purpose was click fraud, a method of earning revenue from fraudulent clicks on advertisements. However, by the time it was discovered, the botnet had clearly been repurposed for DDoS and was receiving attack instructions from command-and-control servers hosted under the same domain name. This is not the first Android-based DDoS botnet ever found, but it is certainly the largest. At the peak of the attacks, the researchers observed malicious traffic coming from over 120,000 unique IP addresses per hour. Last year, security firm Imperva uncovered a similar botnet that was used to launch DDoS attacks from around 27,000 infected Android devices. While Google is making significant efforts to keep malware off Google Play and constantly scans the apps hosted on its platform, this is not the first time when malicious applications have made it past its defenses. Just last week, the company removed applications that were using an advertising toolkit with spying capabilities and in May the company removed around 40 apps that included click fraud functionality.

Tech firms band together to take down Android DDoS botnet

An ad-hoc alliance of tech firms has managed to seriously cripple an Android-based botnet that was being actively used to DDoS multiple content providers. The botnet, dubbed WireX by the researchers, consisted of Android devices with malicious apps installed. In fact, in the wake of the discovery, Google has pulled some 300 such apps from Google Play, began removing them remotely from affected users’ devices, and blocked them from being installed. The malicious apps The … More ?

3 Ways to Defeat DDoS Attacks

In 2012, a number of DDoS attacks hit Bank of America, JPMorgan Chase, Wells Fargo, U.S. Bank and PNC Bank. These attacks have since spread across most industries from government agencies to local schools and are showing an almost yearly evolution, with the most recent focus being the Internet of Things (IoT). In 2016, compromised cameras, printers, DVRs and other IoT appliances were used in a large attack on Dyn that took down major websites including Amazon, Twitter, Netflix, Etsy and Spotify. Inside Distributed Denial-of-Service Threats Although these large attacks dominate the headlines, they’re not what most enterprises will deal with day to day. The most common attacks are in the range of 20 to 30 Gbps or less, while larger attacks have been reported at 1.2 tbps. Creating DDoS Defense Security technology is becoming more sophisticated, but so are hackers, which means attacks can be much more difficult to mitigate now than in the past. Enterprises must be knowledgeable and prepared with mitigation techniques as the attacks continue to evolve. DDoS mitigation comes in three models: Scrubbing Centers The most common DDoS mitigation option for enterprises is to buy access to a scrubbing center service. During an attack, traffic is redirected to the security provider’s network, where the bad traffic is “scrubbed out” and only good traffic is returned to the customer. This option is good for multi-ISP environments and can be used to counter both volumetric and application-based attacks. For added protection, some providers can actually place a device in your data center, but this is not as cost-effective as the cloud-based option. ISP- Clean Pipes Approach With the rise of DDoS attacks, many ISPs have started their own scrubbing centers internally, and for a premium will monitor and mitigate attacks on their customers’ websites. In this scenario, ISPs operate as a one-stop-shop for bandwidth, hosting and DDoS mitigation. But some ISPs are more experienced at this than others, so customers must be sure to thoroughly test and research the quality of the service offered by their ISPs. Content Delivery Network Approach The distributed nature of content delivery networks (CDNs) means that websites live globally on multiple servers versus one origin server, making them difficult to take down. Large CDNs may have over 100,000 servers distributing or caching web content all over the world. However, CDN-based mitigation is really only a good option for enterprises that require core CDN functionality, as porting content to a CDN can be a time-intensive project.

DreamHost, web hosting company, blames powerful DDoS attack for online outages

DreamHost, one of the world’s largest web hosting companies, said a distributed denial-of-service (DDoS) caused significant outages Thursday affecting customers of its web and email services. The Los Angeles-based hosting provider said that “internet vigilantes” conducted an attack against part of its online infrastructure resulting in connectivity issues affecting several aspects of its operations, ranging from its online customer support features to the hosting service used by over 1.5 million websites. The attack targeted DreamHost’s Domain Name Servers (DNS) – digital directories that allow internet users to access specific websites without remembering their lengthy, numeric IP addresses – and was remedied about four hours after first being detected, according to the company. DDoS attacks involve knocking websites offline by overloading their servers with illegitimate traffic and effectively rendering them inaccessible. Low-level attacks are capable of briefly disabling websites lacking DDoS protection, but wide-scale attacks like the one conducted last year against Dyn, an American DNS provider, caused unprecedented outages affecting some of the world’s most popular websites, including Amazon and Netflix. DreamHost customers, including the Cambridge Seventh-day Adventist Church in England and the Tale of Two Wastelands video gaming project, were among those who said their websites were unavailable Thursday due to the powerful DDoS attack. The DDoS attack was confirmed by DreamHost as two of the company’s customers made headlines in their own right over their unrelated efforts to survive scrutiny: DisruptJ20, an anti-Trump protest site, and The Daily Stormer, a white supremacist website that remerged online this week with the help of DreamHost after being all but driven off the internet. A federal judge earlier Thursday ordered DreamHost to provide information sought by federal prosectors investigating the riots that erupted in Washington, D.C. during President Trump’s inauguration Jan. 20. The Daily Stormer, meanwhile, relaunched on a DreamHost website Thursday after previously being banned from the internet’s biggest domain registrars and hosting providers, including GoDaddy, Google and Cloudflare. The Daily Stormer had quietly registered the new domain using an automated signup form and was subsequently booted several hours later, , DreamHot said Thursday evening. “Unfortunately, determined internet vigilantes weren’t willing to wait for us to take that action,” DreamHost said in a statement to Ars Technica. “They instead launched a DDoS attack against all of DreamHost this morning. We were ultimately able to declaw that attack, but the end result was that most of our customers experienced intermittent connectivity issues to their sites today.” Source: http://www.washingtontimes.com/news/2017/aug/24/dreamhost-web-hosting-company-blames-powerful-ddos/
