Vacation over, hacktivists return

By Nicholas Cucci

A group that has dubbed itself the al-Qassam Cyber Fighters boasted in late July the beginning of "phase four" of its distributed denial-of-service (DDoS) attacks against U.S. banks. The hacktivist group had not attacked American banks since early May 2013.

The attacks are retaliation for the continued availability on YouTube of a video clip the group has deemed offensive to Islam.

In a July 23 Internet post, the group stated it plans to disrupt the service of American banks until all clips of the film are removed from YouTube. "Planning in the new phase will be a bit different and you'll feel this in the coming days," the post stated. For more details, see http://pastebin.com/22WJ6m9U.

JPMorgan Chase & Co., U.S. Bancorp, and Regions Financial Corp. reportedly have all had intermittent issues since July 24. A DDoS attack on July 27 was aimed at Regions, which stated on its website that customers may have had difficulty using their debit cards.

The DDoS was a large-scale attack and had the potential to affect many customers. However, the issue lasted only two hours. "Attacks like this have not been uncommon this year for us or, frankly, for any other major banks," Regions Bank spokesman Mel Campbell told thetowntalk.com.

The outage at Chase on July 24 was heavy in the early morning, stopped in the late morning and ramped up again in the afternoon, said a DDoS expert who asked to remain anonymous. The outages at Regions Bank followed the same pattern.

Growing bigger and shorter

According to Arbor Networks Inc., at the end of 2012 the average size of DDoS attacks was around 1.77 Gigabits per second (Gbps), reflecting 19 percent growth over comparable attacks in 2011.

Following are a few recent statistics from Arbor regarding DDoS attacks:

Arbor also found that attacks are shorter, with most lasting less than one hour. Packet-per-second attack sizes have diminished, reversing the strong growth seen from late 2011 through 2012.

"The increasing volume of highly visible attacks - including a mix of politically motivated attacks, state-sponsored electronic warfare, social activism, organized crime, and good old-fashioned pointless mischief and mayhem - is being driven by the easy availability of bots/botnets for hire and easily distributed crowd-sourced attack tools," stated Jeff Wilson, Principal Network Security Analyst with Infonetics Research, in Arbor's announcement.

Mitigating risk

How can you fight DDoS? You can't prevent an attack; it is out of your control; everyone is vulnerable. DDoS attacks are cheap to launch and expensive and tough to battle. Yet, enterprise-level companies can mitigate the risk.

DDoS prevention systems direct traffic through a wider bandwidth, but they won't protect against everything. Addressing and securing bottlenecks inside a corporate network will help.

Also, be aware of application-layer attacks. Unfortunately, this type can be hard to track. Keep potential DDoS attacks such as user datagram protocol flooding and TCP (transmission control protocol) SYN (synchronization packet) floods in check.

These attacks are typically spoofed rather than accomplished by using real Internet protocol addresses from real machines that run complete application transactions.

Another option is to use third-party services, such as those provided by Akamai Technologies Inc., VeriSign Inc. and CloudFlare Inc. for DDoS protection. Even cloud-based protection is now available.
