CISA: Here’s how you can foil DDoS attacks

In light of the rise of “DDoS hacktivism” and the recent DDoS attacks aimed at disrupting French and Alabama government websites, the Cybersecurity and Infrastructure Security Agency (CISA) has updated its guidance of how governmental entities (but also other organizations) should respond to this type of attacks. DDoS attacks explained First and foremost, the document explains the main difference between a DoS attack (from a single source) and a DDoS attack (from multiple sources). “The … More ?

Biggest British Hosting Company 123-Reg Suffers Major DDoS Attack

123-Reg, the biggest hosting company in the UK, is targeted a second time in as many years with a chain of major DDoS attacks. The biggest provider of domain registrations in the UK, 123-reg, has once again been the target of a DDoS attack. The result was that users weren’t able to get into their websites or email accounts. Considering this is just the start of 2017, the company has had to deal with another major blow. The company informed of the attacks formally using Twitter, explaining that they believed the attack had just begun and they were working on options to redress the situation and were attempting to work out the impact of the attack. They promised updates would follow. They continued to explain that the company’s network teams kept scrubbing and rerouting bad traffic. Of course, apologies were made for any problems their customers were experiencing. Once again, they reiterated that their team was still rerouting traffic and that they would provide further information soon. The DDoS attack took place on Friday, with the company stating that their IT team had mitigated the DDoS attacks, as evidenced by the resumption of services at around 1 PM. However, some users are still complaining today that they can’t get into their websites. 123-Reg sent out another two tweets in which they attempted to explain that the DDoS attack had just begun and they were attempting to resolve the issue. Later that day, they issued another tweet, stating that the problem had been fixed by 1 PM and that they apologized for any issues. In 2016, 123-Reg was the target of 2 big DDoS or Distributed Denial of Service, attacks. One took place in April, while one occurred in August. The firm stated that it was possible they lost a small amount of user information after the attack that occurred in April. Customers were very displeased at the time because, even after doing their best, the firm only succeeded in bringing back online only 39 percent of their Virtual Private Servers after a week. In August, the company was once again hit by a huge 30Gbps DDoS attack, which completely brought their site down. OVH, a French hosting company, was also the target of large DDoS attacks going up to 1Tbps last year. The firm stated that the Mirai botnet malicious code had been used in the attacks against them but 123-Reg did not make any similar statements.

Here’s how security cameras drove the world’s biggest DDoS attack ever

DDoS attacks are reaching monster levels that pose a massive threat The record for the biggest DDoS attack ever seen has been broken once again, with an absolute monster of distributed denial of service firepower managing to almost reach the not-so-magic 1Tbps mark. Technically this was actually two concurrent attacks, although the majority of the traffic was concentrated in one, which is the largest ever recorded single blast of DDoS. As the Register reported, Octave Klaba, the founder and CTO of OVH.com, the French hosting company which suffered the attack, said that the assault consisted of two simultaneous barrages of 799Gbps and 191Gbps, for a total of 990Gbps. The previous largest DDoS was the recent 620Gbps effort that hit ‘Krebs On Security’, the website of security researcher Brian Krebs, which was driven by the same botnet of some 150,000+ compromised Internet of Things devices, routers, DVRs and security cameras responsible for this latest volley. Krebs said he was hit in retaliation to an article posted on his blog, although it isn’t clear why OVH.com came under fire. Massive attacks As Klaba said on Twitter, though, it’s hardly uncommon for his company to experience DDoS, and a tweet outlining the attacks suffered by the organisation over a period of four days this month showed 25 separate attacks which all exceeded 100Gbps (including the two mentioned here). Several others were simultaneous (or near-simultaneous) pairs of attacks, too. He further noted that the botnet in question could potentially up its firepower by some 50% compared to the assault his  company  was hit by, tweeting: “This botnet with 145,607 cameras/dvr (1-30Mbps per IP) is able to send > 1.5Tbps DDoS.” Not only are DDoS attacks getting larger in size, but they are also becoming much more frequent according to a VeriSign report we saw back in the spring – this observed that the number of attacks had almost doubled in the final quarter of 2015, compared to the same period in the previous year.
