FINAL WORD Hamman says the IoT brings new demands and requirements to DDoS protection. He adds, “The Mirai IoT botnet reminds us that manufacturers and vendors also have a growing responsibility with respect to their technology and how it will be applied in diverse environments. They need to test for and consider the potential for exploitation. Ideally, all devices should be assessed for risk at the manufacturer and then again by those who are responsible for selling/implementing them in enterprises.” – Dutch anti-spam website Spamhaus is targeted for naming and blacklisting cybercrime hosting enterprises, spam and botnet operations. • 2014: PlayStation Network and Xbox Live are attacked on Christmas Day. • 2014: In Hong Kong, a huge attack is carried out against the territory’s pro-democracy websites. While many assumed that the culprit would have been the Chinese government, this is not necessarily certain. The attacker could, however, be someone who is not sympathetic with the Hong Kong democracy movement, or someone trying to make the Chinese government look bad. • 2015: The Turkish Internet is hit with a massive DDoS attack, which came in the wake of Turkey shooting down a Russian military aircraft. • 2015: British phone and broadband provider, TalkTalk, which has over four million UK customers, is hit by a DDoS attack, which is used as a smokescreen while customers’ personal information is stolen. • 2015: On New Year’s Eve of 2015, the BBC’s entire domain, including its on- demand television and radio player, is down for three hours and continues to have issues for the rest of the day. The attack is claimed by a group called the ‘New World Hackers’. • 2016: An IoT botnet targets a major international event with sophisticated, large-scale DDoS attacks sustaining 500 Gb/sec in attack traffic for the duration of the event. www.intelligentcio.com • 2016: The Mirai IoT botnet launches 1Tbps multi-vector DDoS attack against DNS infrastructure, taking many of the world’s most popular websites offline. Looking forward – where to from here? Hamman says, “We can see clearly, when we look at the timeline of some of the most prominent DDoS attacks over the past two decades, that perpetrators launch these attacks for a variety of reasons. They can be hackers who want to make a statement, as in the case of Mafiaboy; governments of countries at war using cyberwarfare tactics as part of their general arsenal; and criminals trying to blackmail online businesses. “There are also examples when cyber activists show displeasure against their targets, such as the 2011 attacks by members of Anonymous against the sites of PayPal, Visa and MasterCard, and the 2013 attacks against Spamhaus. The online gaming industry has also been targeted, with the blame generally going to disgruntled players or even competitors. We’ve also seen instances when DDoS attacks are used as a smokescreen to camouflage or draw attention away from other criminal activity an attacker might be doing, such as stealing data from the victim’s network, as in the 2015 example of the UK telecom TalkTalk.” Hamman concludes, “Previously, it used to be that only certain types of business would be likely targets for a DDoS attack, with finance, gaming and e-commerce at the top of the list. Today, any business, for any reason, can become a target of a DDoS attack. A number of DDoS-for-hire services, for example, will take down a competitor’s website for any business that wants to hire them. “The only answer, therefore, is to ensure you are protected. Arbor provides the industry’s most comprehensive suite of DDoS attack protection products and services for the enterprise, cloud/hosting and service provider markets, with the required deployment model, scalability and pricing flexibility to meet the DDoS protection needs of any organisation operating online today.” n “The Mirai IoT botnet reminds us that manufacturers and vendors also have a growing responsibility with respect to their technology and how it will be applied in diverse environments.” INTELLIGENTCIO 81
