185,000+ vulnerable Wi-Fi cameras just waiting to be hijacked

A generic wireless camera manufactured by a Chinese company and sold around the world under different names and brands can be easily hijacked and/or roped into a botnet. The flaw that allows this to happen is found in a custom version of GoAhead, a lightweight embedded web server that has been fitted into the devices. This and other vulnerabilities have been found by security researcher Pierre Kim, who tested one of the branded cameras – … More ?

How Homeland Security plans to end the scourge of DDoS attacks

The agency is working on a multimillion dollar effort to protect the country’s most critical systems from distributed denial of service attacks, which are among the simplest digital assaults to carry out and the toughest to fight. MARCH 8, 2017 —In late October, in Surprise, Ariz., more than 100 phone calls bombarded the police department’s emergency dispatch line. Calls also overwhelmed the nearby city of Peoria’s 911 system and departments across California and Texas. But each time a dispatcher picked up, no one was on the line – and there was no emergency. The Arizona district attorney’s office says the calls clogging 911 lines resulted from a digital prank, which triggered a distributed denial of service, or DDoS, attack on critical emergency communication systems. The prosecutor’s office tracked the torrent of calls to 18-year-old hacker Meetkumar Hiteshbhai Desai. Now, he’s facing four counts of felony computer tampering. While Mr. Desai said he didn’t intend to cause any harm, according to the Maricopa County Sheriff’s Office, he did surface a potentially devastating glitch in smartphone software that could exact damage on any number of sensitive and critical targets. Whenever anyone clicked a certain link on his webpage via a mobile device, their phone automatically dialed 911. While this kind of DDoS targeting 911 systems is unprecedented, it’s exactly the type of attack that national law enforcement officials have been concerned about for years. In fact, the Homeland Security Department (DHS) has been working on technology to protect 911 centers from DDoS and telephone-based, or TDoS, attacks for three years. The Arizona incident proved someone can “cause a large number of phones or a large number of computers or a large number of whatever connected device to start generating these calls,” says Dan Massey, program manager in the cybersecurity division of the DHS Science and Technology Directorate. “It went from how much damage can I do from my phone” to a situation where, with just a handful of people, “if all of our phones started calling some victim, whether that’s 911 or a bank or a hospital, that can get very fast and very big.” DDoS attacks are both among the simplest forms of cyberattacks to carry out and the most difficult to defend against. They are designed to direct an overwhelming amount of digital traffic – whether from robocalls or web traffic – at targets to overwhelm them so they can’t handle legitimate business. Writ large, there has been an exponential increase in the intensity and frequency of DDoS attacks over the past six months and critical infrastructure components are possible future targets, according to DHS. For a sense of the scale of today’s DDoS attacks, compare the 100 megabits per second Internet speed at a typical company to the more than 1 million megabits (1 terabit) per second speed of a DDoS attack against Web hosting company Dyn in October. The attack, which drew power from insecure webcams and other internet-connected devices, knocked out widely used online services like Netflix, Twitter, and Spotify for hours. Such massive web DDoS assaults may also become a problem for 911, as the country moves toward a next generation 911 system that uses mapping services to locate callers and can support voice, text, data, and video communication. “What you’re seeing is a convergence of the traditional internet with the phone system and next generation 911 is a great example of that,” says Massey. “DDoS attacks and/or TDoS attacks kind of blend together a little bit there.” To help combat the problem, the department has given out $14 million in grants for DDoS prevention studies, including phone-based attacks. Some of that funding is piloting initiatives to stop phone-based attacks at 911 centers in Miami/Dade County and the City of Houston, as well as at a large bank that the department wouldn’t identify. So far, DHS efforts have yielded, among other things, a DDoS early warning system to flag organizations that an attack may be coming, and alerting them to adjust internet network settings to defend against an onslaught of traffic. Additionally, DHS-funded research from tech firm SecureLogix produced a prototype that can thwart phony telephone calls sent to a 911 system or other critical phone operation. The model attempts to detect bogus calls by monitoring for clues that indicate an incoming call is fake. “As we have seen, it is simple to flood a 911 center, enterprise contact center, hospital, or other critical voice system with TDoS calls,” says Mark Collier, SecureLogix chief technology officer. “The research is essential to get ahead” because the assailants “are generating more attacks, the attacks are more sophisticated, and the magnitude of the attacks is increasing. “ To be sure, the race to keep digital adversaries out of the country’s 911 system faces obstacles, some of which are outside the jurisdiction of Homeland Security and dispatch centers. The DHS DDoS defense program is “a good start,” but one “challenge in defending certain types of critical infrastructure is the fact that emergency services like 911 must serve anyone – immediately,” per Federal Communications Commission rules, “due to their life saving nature,” said Mordechai Guri, research and development head at Israel’s Ben-Gurion University Cyber-Security Research Center. “The approach of blocking the DDoS originators must be backed by a change in the laws and regulations.” Before the October attacks on the Arizona 911 systems, he and fellow Ben-Gurion researchers warned that DDoS attacks launched from cellphones could pose a significant threat to emergency services. During one experiment, it took fewer than 6,000 hacked phones to clog emergency services in a simulated US state, the academics wrote in a September 2016 paper. Such an attack can potentially last for days. The very nature of the 911 system makes shutting out any callers potentially dangerous, and some alternatives, like requiring a person in distress to authenticate themselves for assistance, are not viable, says Massey of DHS. “We really need to make sure that we’re not missing a critical 911 call,” he says. “So that’s a challenge for the project to make sure that we’re not misclassifying people.” Source: http://www.csmonitor.com/World/Passcode/2017/0308/How-Homeland-Security-plans-to-end-the-scourge-of-DDoS-attacks

7 Security Steps To Defend Your Company Fram A DDoS Attack

Of all the cybersecurity threats today’s businesses face, distributed denial-of-service (DDoS) attacks are among the most complex and devastating. This type of breach involves multiple compromised systems that work in conjunction to shut down service. Although security technology is becoming more sophisticated, so are hackers, and you don’t want to be caught unprepared if (or more likely, when) your company’s data gets compromised. Below, a few members of Forbes Technology Council each offer one important prevention measure to help your IT department defend against a DDoS attack. 1. Continue To Add Layers Of Defense Remain vigilant, continuing to add layers of security as they become available. Also provide your department with signs to look for so they have a better idea of potential threats. This provides for a much more proactive approach to security. – Chalmers Brown, Due 2. Practice Your Response Plan Have a plan on what to do and who should do it, then do a dry run against it a few times a year. Go further than just your IT team – involve your vendors, executive team, etc. and ask for feedback on what would help them help you in the face of a DDoS attack. Update your plan each time. This practice helps your team execute fast and has the added benefit of showing those around you that you’re prepared. – Brian Fritton, Patch of Land 3. Use A Web Application Firewall (WAF) A Web Application Firewall (WAF) is your best line of defense against a DDoS attack. It acts like an antivirus that blocks all malicious attacks on your website. It sits above your application at the network level to provide protection before the attacks reach your server. Using a WAF not only protects you against DDoS attacks, but also improves application performance and enhances user experience. – Thomas Griffin, OptinMonster 4. Leverage Cloud Services And Educate Yourself Continually Cloud providers will handle security better than you can do in-house — especially if you’re a target. Even the U.S. government leverages cloud providers to consult and augment security. Amazon has DDoS mitigation services, and their DNS is both inexpensive and secure. Educate yourself to stay aware of the potential threats and mitigation services that are available to you. – Tim Maliyil, AlertBoot 5. Help Employees Educate Each Other Since our inception, we’ve had a personal ‘buddy’ assigned to any new team member. They are responsible for teaching the new person all of the dos and don’ts of the department, and also get them more culturally aligned with the team/company. – Pin Chen, ONTRAPORT 6. Get Senior Management Involved In Security Planning It is critical for companies to include senior management in DDoS prevention planning. Most attacks are due to poor ongoing security practices or setups. Ransomware attacks alone cost over $1B in 2017. Companies should consider cloud solutions that offer cost-effective managed security solutions, with ongoing security and maintenance updates, so that they can focus on building their core business. – Cristina Dolan, Trading Screen 7. Segment Your IoT Devices Behind A Firewall While DDoS attacks are difficult to prevent, you can minimize the impact by enabling DDoS and flood protection on your organization’s firewalls. To restore order quickly in the event of an attack, develop a DDoS response plan. To minimize the chance of your IoT infrastructure being used in a DDoS attack, make sure all IoT devices are segmented on a dedicated safe zone behind a firewall. – Bill Conner, SonicWall Source: https://www.forbes.com/sites/forbestechcouncil/2017/03/07/7-security-steps-to-defend-your-company-fram-a-ddos-attack/#4a04a540408

Businesses blame rivals for DDoS attacks

Industrial sabotage is considered to be the most likely reason behind a distributed denial of service attack, a study has revealed More than 40% of businesses hit by a distributed denial of service (DDoS) attack worldwide believe their competitors were behind it, research by Kaspersky Lab and B2B International has revealed. Rival firms are considered more likely culprits than cyber criminals, which were cited as suspects by just 38% of DDoS victims on average. Industrial sabotage is considered to be the most likely reason behind a DDoS attack, coming out higher than political conspiracy and personal vendettas against a business. Typically, DDoS attacks target web servers and aim to make websites unavailable to users. Although no data is stolen, the interruption to the service can be costly in terms of lost business damage to reputation. For example, a massive DDoS attack on Luxembourg’s government servers that started on 27 February 2017 reportedly lasted more than 24 hours, and affected more than a hundred websites. The joint Kaspersky Lab, B2B International study, which polled 4,000 businesses in 25 countries, found that only 20% of DDoS victims overall blamed foreign governments and secret service organisations, with the same proportion suspecting disgruntled former employees. Companies in Asia Pacific are the most suspicious of competitors, with 56% blaming their rivals for DDoS attacks and 28% blaming foreign governments. Personal grudges also carry more suspicion in the region too, with 33% blaming former staff. In Western Europe, only 37% of companies suspect foul play by their competitors, with 17% blaming foreign governments. Looking at attitudes by business size, businesses at the smaller end of the scale are more likely to suspect their rivals of staging an experienced DDoS attack. The study found that 48% of small and medium business representatives believe this to be the case compared with only 36% of enterprises. In contrast, respondents from big companies put more blame on former employees and foreign governments. “DDoS attacks have been a threat for many years, and are one of the most popular weapons in a cyber criminals’ arsenal,” said Russ Madley, head of B2B at Kaspersky Lab UK. “The problem we face is that DDoS attacks can be set up cheaply and easily, from almost anyone, whether that be a competitor, a dismissed employee, socio-political protesters or just a lone wolf with a grudge. “It’s therefore imperative that businesses find an effective way to safeguard themselves from such attacks,” he said. Significant advances in DDoS attacks There were significant advances in DDoS attacks in the last quarter of 2016, according to Kaspersky, with the longest DDoS attack in lasting 292 hours or 12.2 days, which set a record for 2016 and was significantly longer than the previous quarter’s maximum of 184 hours. The last quarter of 2016 also saw the first massive DDoS attacks using the Mirai IoT (internet of things) botnet technology, including attacks on Dyn’s Domain Name System (DNS) infrastructure and on Deutsche Telekom, which knocked 900K Germans offline in November. There were also similar attacks on internet service providers (ISPs) in Ireland, the UK and Liberia, all using IoT devices controlled by Mirai technology and partly targeting home routers in an attempt to create new botnets. Stakeholders recognise lack of security in IoT devices According to Kaspersky, stakeholders worldwide, in particular in the US and EU, recognise the lack of security inherent in the functional design of IoT devices and the need to set up a common IoT security ecosystem. Kaspersky expects to see the emergence of further Mirai botnet modifications and a general increase in IoT botnet activity in 2017. Researchers at Kaspersky Lab also believe that the DDoS attacks seen so far are just a starting point initiated by various actors to draw up IoT devices into the actors’ own botnets, test drive Mirai technology and develop attack vectors. First, they demonstrate once again that financial services like the bitcoin trading and blockchain platforms CoinSecure of India and BTC-e of Bulgaria, or William Hill, one of Britain’s biggest betting sites, which took days to come back to full service, were at the highest risk in the fourth quarter and are likely to remain so throughout 2017. Second, cyber criminals have learnt to manage and launch very sophisticated, carefully planned, and constantly changing multi-vector DDoS attacks adapted to the mitigation policy and capacity of the attacked organisation. Kaspersky Lab’s analysis shows that the cybercriminals in several cases tracked in 2016 started with a combination of various attack vectors gradually checking out a bank’s network and web services to find a point of service failure. Once DDoS mitigation and other countermeasures were initiated, researchers said the attack vectors changed over a period of several days. DDoS enters its next stage of evolution Overall, they said these attacks show that the DDoS landscape entered the next stage of its evolution in 2016 with new technology, massive attack power, as well as highly skilled and professional cyber criminals. However, the Kaspersky researchers note that unfortunately, this tendency has not yet found its way into the cyber security policies of many organisations that are still not ready or are unclear about the necessary investments in DDoS protection services.

Luxembourg government servers forced offline by DDoS attack

Authorities in Luxembourg have said that government servers had come under a DDoS attack on Monday. According to reports from the Luxemburger Wort, the attack started at 9.30 am, forcing the web servers of many state authorities offline or difficult to reach. Just over an hour later, the state-owned IT operator “Centre des Techniques de l’information de l’Etat” (CTIE) sent a message via Twitter, to confirm that the network was the victim of a DDoS attack. Reports by Luxemburg publication Paperjam said that over a hundred servers had been affected by the attack and that the attack impacted servers for more than 24 hours. Gilles Feith, chief of the CTIE government IT centre, said that this was the first-time Luxembourg authorities had been targeted to such an extent but could not confirm the origin of the attack. “Before it gets back to normal, it may take some time to wait,” said Feith, adding it may take “a few hours or even days.” Stephanie Weagle, VP, Corero Network Security, told SC Media UK that DDoS attacks have become many things over the last decade; weapons of cyberwarfare, security breach diversions and service impacting strategies. “The motivations for these attack campaigns are endless – financial, political, nation-state, extortion and everything in between,” she said. Weagle added: “Continuing to rely on traditional IT security solutions, and or human intervention to deal with the growing DDoS epidemic will continue to prove devastating to businesses. As recent events have confirmed once again, proactive, automated protection is required to keep the Internet connected business available in the face of DDoS attacks.” Pascal Geenens, Radware EMEA security evangelist, told SC Magazine that these days anyone has access to booter or stresser services or DDoS-for-hire. “Services are available on the Darknet as well as on the Clearnet and for just a couple of Euros one can launch a DDoS attack by a click of the mouse,” he said. Geenens added the release of the Mirai source code last October was a turning point. “We saw a huge rise in the number of botnets leveraging IoT devices (mostly IP cams and residential routers) and attacks grew in size. A 1Tbps attack should not come as a surprise today, the potential certainly is there.” He said the motivation behind DDoS attacks can be many things, combined with the user-friendly experience and low price provided by the services to perform them, the spectrum of motivations is only widening. “The main drive of most cyber-crime is still money, we have witnessed countless cyber-ransoms leveraging DDoS. This attack could be precursor of a larger RDoS. Attackers typically provide some proof they have the ability to interrupt the service, which is typically followed by a message with a demand for ransom and if the victim does not pay there will be an ultimatum followed by a much larger and longer attack.” Geenens said the number and size of DDoS attacks is growing and we do not predict this trend will slow in the near future. “My advice to any online business or government, it is five past 12, everybody is a potential target. Make DDoS protection a priority. UEBA is another technology that should be part of the strategy for organisations that carry important or sensitive information.” Source: https://www.scmagazineuk.com/luxembourg-government-servers-forced-offline-by-ddos-attack/article/641003/
