End of Quarter DDoS Attacks Reach New Level of Size and Sophistication

desc

HOLLYWOOD, Fla., Oct. 1, 2012 (GLOBE NEWSWIRE) -- Prolexic Technologies, the global leader in distributed denial of service (DDoS) protection services, today warned of an escalating threat from unusually large and highly sophisticated DDoS attacks.



The DDoS attacks have been launched in the last week using the so-called itsoknoproblembro DDoS toolkit. The malicious actor(s) behind the attacks have used this potent tool in conjunction with sophisticated attack methods that clearly demonstrate knowledge of common DDoS mitigation methods. The attack signatures are extremely complex and Prolexic has recorded sustained floods peaking at 70 Gbps and more than 30 million pps against some of its customers. Most mitigation providers would struggle to combat DDoS attacks with these characteristics.

"What we are experiencing is a dramatic uptick in the size and sophistication of DDoS attacks to a level not previously observed," said Prolexic Chief Executive Officer Scott Hammack. "Only a handful of companies around the world could survive a hit of 70 Gbps in conjunction with the complex blend of attack vectors we have witnessed."

The itsoknoproblembro toolkit includes multiple infrastructure and application-layer attack vectors, such as SYN floods, that can simultaneously attack multiple destination ports and targets, as well as ICMP, UDP and SSL encrypted attack types. A common characteristic of the attacks is a large UDP flood targeting DNS infrastructures. Uniquely, the attacking botnet contains many legitimate (non-spoofed) IP addresses, enabling the attack to bypass most anti-spoofing mechanisms.

"The size and sophistication of this threat has created a high-alert within various industries and with good reason," said Hammack. "I'm proud to say we've successfully mitigated multiple itsoknoproblembro campaigns throughout the year, even when attack vectors have continuously modulated during the course of the assault."

The Prolexic Security Engineering & Response Team (PLXsert) has been monitoring the itsoknoproblembro suite and issued an internal threat advisory to Prolexic customers earlier this month. A case study with more details about the toolkit will be included in Prolexic's quarterly attack report, which will be published in mid-October, along with a public threat advisory that includes fingerprinted attack signatures for recommended detection and mitigation strategies. The latest threat advisories are available to the public at www.prolexic.com/threatadvisories.
