The contract between Department of Homeland Security (DHS) and Galois was signed in January. However, HackRead had a chance to discuss the contract with Galois. Galois and the Department of Homeland Security (DHS) Science and Technology Directorate (S&T) have formalized a contract to develop technology for preventing and combating extensive, sophisticated DDoS (Distributed Denial of Service) attacks . In fact, an official announcement was made by Galois in which the company informed media about signing up a $1.7million contract with the DHS S&T Cyber Security Division. The contract is part of the larger Distributed Denial of Service Defenses (DDoSD) program initiated by the DHS S&T Cyber Security Division. The problem with DDoS attacks is that these can cripple even the most established and largest organizations. These happen to be devastating for small and/or medium-sized businesses. The generated amount of traffic is adequate to drench their internet connections multiple times and it becomes challenging to get the ISP (internet service provider) to take the matter seriously and respond quickly. DHS Developing Technology to Thwart DDoS attacks Quicker than Ever Before The project that DHS is planning with Galois is dubbed as DDoS Defense for a Community of Peers (3DCoP) and it involves peer-to-peer collaboration mechanism with which the organizations detect and combat DDoS attacks by working in cooperation. According to Adam Wick, Galois’ Research Lead, Mobile & Security Systems Software: “Current DDoS defense systems are proving ineffective because they operate in isolation, which introduces delays in the detection, reporting, and response to a DDoS attack. This delay is critical. It provides positive feedback to the attacker, who will continue to send more and more traffic to the target network. Our solution advances the state of DDoS defense by providing new tools that allow multiple defenders to coordinate their response, resulting in earlier detection and faster DDoS mitigation.” It is not a hidden fact that DDoS attacks are a great threat for all kinds of industries and sectors alike such as news entities, financial institutions, critical infrastructure organizations and government agencies, etc. Under the contract with DHS, Galois aims to curb rising DDoS attack threats via the following measures: 1: Minimizing mitigation response duration by at least 50% and 75 to 90 percent reduction in peak traffic 2: 25% reduction in the duration between the launching of DDoS attack and its detection Resultantly, organizations and institutional entities will be able to thwart DDoS attacks prior to its completion. HackRead had a chance to have a conversation with Adam Wick and here’s what we asked and what he replied: Q: How would you like to explain the difference between your services and services provided by other companies? Answer: “Currently, DDoS defense systems fail to address large DDoS attacks that fully “clog” the internet connection. In those cases, locally responding to an attack is no longer possible. In general, most solutions work in isolation, which introduces delays in the detection, reporting, and response to a DDoS attack. To effectively mitigate a large attack, an organization must involve organizations “higher up”, like ISPs, that can stop the flow of malicious traffic. We’re developing a unique collaborative model, where multiple organizations automatically work together to detect DDoS attacks through automatic traffic analysis. They then generate traffic blocking rules for the malicious traffic and send that to ISPs further up the chain. The ISPs can, in turn, block the necessary traffic and mitigate the attacks. One can see the basis of this in the way people react to DDoS attacks now, but many of these steps are manual and require complicated conversations over the telephone. In many cases, the process is further complicated because the parties involved have never spoken before, and have to build trust. After all, the actions that one takes to mitigate a DDoS can also be used to perpetrate an attack, so upstream ISPs need to convince themselves that they’re talking to the right person. What we’re looking to do is speed up this process, dramatically, by automating the detection, analysis, and mitigation steps. At the moment, this mitigation can be automatic, or it can be manual. That way, even if an organization’s ISP isn’t hooked up to our system, network admins will be able to detect the problem early and trust our solution to have all the information (and all the evidence!) they need to convince their ISP to take early and effective action.” Q: How will your firm will defend its client against DDoS attack leading to ransom such as the ProtonMail DDoS attack? Answer: “Ransom in DDoS cases is one of those clear indicators that our current approaches to DDoS defense are failing. Attackers can only ask for ransom when an organization has no way to defend themselves. Ransom cases can be mitigated by having effective DDoS defense that doesn’t allow an attack to become a problem in first place. The most effective defenses in the coming years will take into account the bigger picture by connecting everyone involved, for a more timely response. If we can minimize the effect of large DDoS attacks, we effectively reduce cases where attackers demand ransom.” Galois is a renowned firm in the computer science research and development sector. It has been operating since 1999 and boasts of a world class team of computer science experts, mathematicians, programmers, and engineers. The firm has positioned itself as the world’s most reliable company and is ready to take on even the most challenging computer science related task of the world.

FBI arrests Massachusetts man for Anonymous 2014 cyberattack on Boston Children’s Hospital
The hacktivist group launched multiple distributed denial-of-service attacks against the hospital’s servers in protest of the controversial custody case of Justina Pelletier. The FBI has arrested a hacker suspected of participating in Anonymous’ 2014 DDoS attack against Boston Children’s Hospital, The Boston Globe has reported. He was taken into custody after being rescued from a small boat off the coast of Cuba by a Disney cruise ship. Martin Gottesfeld, 31, of Somerville, Massachusetts, was arrested on Feb. 17 in Miami. He’s due to appear in U.S. District Court in Boston, where he’ll be charged with of conspiring to damage the computers at Boston Children’s and another facility in Framingham, Massachusetts, according to the Globe. He faces up to five years in prison and a $250,000 fine. In April 2014 – in protest of the controversial custody case of Justina Pelletier, who was being kept a patient at Boston Children’s as a ward of the state against the wishes of her parents – hacktivist group Anonymous launched multiple distributed denial-of-service attacks that targeted the hospital’s servers and hamstrung its operations for a week. According to the Globe, the FBI had previously questioned Gottesfeld in 2014. He admitted then that he had posted a YouTube clip calling for attacks on Boston Children’s, but denied participating in them. It’s unclear why he wasn’t charged at that time. But a tip this week about his rescue at sea led agents to Florida to take him into custody. He had three laptops with him, according to an FBI affidavit. In a statement, Boston Children’s thanked federal officials for “apprehending the hacker who led the attack and holding him accountable” – also thanking its own employees, “who assisted the FBI throughout its investigation and who helped build the comprehensive systems and procedures that were able to thwart the attack and protect confidential information.” Source: http://www.healthcareitnews.com/news/fbi-arrests-massachusetts-man-anonymous-2014-cyberattack-boston-childrens-hospital

Is your WordPress site being misused for DDoS attacks?
Many WordPress websites are still being misused to perform layer 7 DDoS attacks against target servers, even though preventing them from participating in these attacks is as simple as disabling the pingback feature. “If you are not familiar with the terminology, Layer 7 attacks (also known as http flood attacks) are a type DDoS attack that disrupts your server by exhausting its resources at the application layer, instead of the network layer,” Sucuri Security CTO … More ?

Several bugs detected in IBM Java Runtime could lead to DDoS attacks
Multiple vulnerabilities that could enable a remote attacker to launch a denial-of-service attack have been detected in the IBM Runtime Environment Java Technology Edition v6, according to an IBM Security Bulletin posted on Tuesday. The integrated software is used by Tivoli Composite Application Manager for SOA, a platform which provides management for services, applications and middleware. These bugs, which include the vulnerability popularly known as “SLOTH,” were reported by IBM when it updated Java SDK in January 2016. “The TLS protocol could allow weaker than expected security caused by a collision attack when using the MD5 hash function for signing a ServerKeyExchange message during a TLS handshake,” the bulletin stated. Employing man-in-the-middle techniques, a saboteur could exploit this flaw to mimic a TLS server and glean credentials, IBM wrote. No workarounds or mitigations have yet been provided.

How CDSL’s CIO is way ahead in the fight against DDoS attack
As the threat of DDoS attack looms large on the enterprise, CDSL’s CIO, Joydeep Dutta, countered it ahead of time with his in-house DDoS protection. For the past few years, India Inc. and its IT teams have been in a constant state of war with malware, hackers, insidious employees and everything that is a threat to their information security. The only strategy applied—and it wasn’t an effective one—was to deal with the after effects of the attack. But one CIO believed in the age old adage: Prevention is better than cure, and secured the most critical applications of the company from DDOS attacks. “Today, not many companies have implemented in-house DDoS protection though it is the ideal way of preventing denial of service attacks. If done only at the network service provider through clean pipes, it doesn’t give full protection,” says Joydeep Dutta, group CTO, Central Depository Services Limited. According to a recent report released by Akamai, India stands in the fourth position for being the origin of non-spoofed DDoS attacks. Of all the attacks, 7.43 percent originated from the country. The project was therefore a high priority for Dutta as the company’s core depository application, electronic voting for company resolution and other critical applications were Web-based. Not wasting any more time, as the threat loomed large, Dutta implemented an in-house DDoS protection and Web Application Firewall for additional security above the capability of traditional network firewalls. “By implementing Web application firewall (WAF), the internet-facing applications which are part of the core applications for most organizations were additionally protected,” he says. Further explaining the project, Dutta says that the in-premises DDOS equipment is the first layer of defense in the on-premise infrastructure. All the other equipment such as ISP routers, firewalls etc; at customer premise, are underneath this. “A set of security modules including Denial-of-service (DoS) protection, Network Behavioral Analysis (NBA), Intrusion Prevention System (IPS), Reputation Engine and Web Application Firewall (WAF), fully safeguard networks, servers, and applications against known and emerging network security threats,” Dutta says. Another novel thing about the project was the built-in security event information management system which collects and analyzes events from all modules to provide enterprise-wide views. CDSL reaped huge benefits from the on-premise DDoS implementation. “It was easy to proactively monitor the security features of these devices to decide necessary actions to be taken,” he says. It was now easy to black-list the vulnerable IP list received regularly from NCIIPC. It was also possible to stop repeated attacks with the help of the device. Thus, Dutta set an example for his peers to follow by securing the organization against the looming security threats. You too get going.

Denying the deniers: how to effectively tackle DDoS attacks
DDoS as an attack vector is on the rise: here’s how to stop it from stopping your business. Distributed Denial of Service (DDoS) attacks maybe as old as the hills but they continue to be a popular, and highly effective, attack vector for hackers. In the past couple of months alone we have seen a persistent DDoS attack on the UK academic computer network JANET, which was swiftly followed by one against cloud hosting company Linode, leading to service interruptions at DNS infrastructure and data centers across the U.S. and the U.K. Indeed, recent research released by Arbor Networks in its Annual Worldwide Infrastructure Security Report stated that DDoS attacks are on the rise, with half of the 354 global respondents’ data centers suffering DDoS attacks – a 33% increase from 2014. DDoS attacks have increased in frequency for some time – giving hackers a relatively uncomplicated method to bring a website down or disrupt a web service. Although DDoS attacks do not involve the stealing of data, they can be highly damaging in other ways, not least by affecting the trust and reputation that a company has among its customers. This can lead to financial damage through lost customers and lost business. Moreover, DDoS attacks can be used as a diversionary smokescreen for more aggressive attacks, as was the case with the recent TalkTalk breach. So what can organisations do to help protect themselves against the threat of DDoS and mitigate the effects of such attacks? The first step is being able to quickly detect that you are under attack, and having a procedure in place to deal with it. Illegitimate traffic can be hard to distinguish from legitimate traffic, but the typical signs of a DDoS attack are a sharp increase in traffic to your website followed by a slowing down of performance (there are services that can continuously monitor your website’s responsiveness from an external point of view, such as Dynatrace and SolarWinds.) Once a DDoS attack is underway, you have a number of options in terms of dealing with the bombardment: ISP blocking and scrubbing – It is advisable to deal with the attack in an environment that’s removed from your network, to prevent it from affecting other areas of network performance. If you suffer a DDoS attack contact your internet service provider, as many offer DDoS protection services such as blocking the originating IP addresses or ‘scrubbing’ malicious packets. They will also probably have greater bandwidth than you and are therefore likely to be able to deal with the attack more efficiently and effectively. Blackholing – A common response to a DDoS attack is to simply route all website traffic into a black hole, thus taking the website offline until the attack ceases. The problem with this approach is that it blocks all traffic, both good and bad, which basically means that the hacker has achieved their objective. Routers and firewalls – You can set up routers and firewalls policies to filter non-critical protocols, block invalid IP addresses and shut off access to specific high-risk segments of your network in the event of an attack. However, be aware that these techniques are somewhat ineffective against more sophisticated attacks that use spoofing or valid IP addresses. Content delivery network – Using a content delivery network to create replicas of your website for customers in different locations can help reduce the impact of the DDoS attack as well as make the extra DDoS related traffic easier to combat. Anti-DDoS technology – Many of the leading firewall appliance vendors offer specialised anti-DDoS modules, that can be deployed at the perimeter of your network or data center, which are designed to detect and filter malicious traffic. However, these are not automated and need to be constantly managed and updated by your operations team. While there is no single ‘silver bullet’ solution that can stop a DDoS attack in its tracks once the traffic starts hitting your website, you can lessen its impact on your business by using a combination of the methods I’ve outlined here. As DDoS continues to be used as a cyber-weapon against websites and online resources, organisations should ensure that they have a response plan in place that includes these mitigation techniques, to help deny attempted denial-of-service attacks.
