Bonets Attack U.S. Banks

Evidence collected from a website that was recently used to flood U.S. banks with junk traffic suggests that the responsible parties behind the ongoing DDoS attack campaign against U.S. financial institutions — thought by some to be the work of Iran — are using botnets for hire.

The compromised website contained a PHP-based backdoor script that was regularly instructed to send numerous HTTP and UDP (User Datagram Protocol) requests to the websites of several U.S. banks, including PNC Bank, HSBC and Fifth Third Bank, Ronen Atias, a security analyst at Web security services provider Incapsula, said Tuesday in a blog post.

Atias described the compromised site as a “small and seemingly harmless general interest UK website” that recently signed up for Incapsula’s services.

An analysis of the site and the server logs revealed that attackers were instructing the rogue script to send junk traffic to U.S. banking sites for limited periods of time varying between seven minutes and one hour. The commands were being renewed as soon as the banking sites showed signs of recovery, Atias said.

During breaks from attacking financial websites the backdoor script was being instructed to attack unrelated commercial and e-commerce sites. “This all led us to believe that we were monitoring the activities of a Botnet for hire,” Atias said.

“The use of a Web Site as a Botnet zombie for hire did not surprise us,” the security analyst wrote. “After all, this is just a part of a growing trend we’re seeing in our DDoS prevention work.”

Get Ready For Email-Malware Spree

A sizeable uptick in malicious email attachments is just subsiding, but if history is any indicator,several smaller spikes are about to follow that use even more deceptive tactics than their predecessors.

The recent surge, fueled in large part by a flood of fake messages from UPS, is similar to one observed at the end of March in that the messages urge recipients to open an attachment that releases the malware on victims’ machines, according to Internet security firm Commtouch.

The earlier wave used a wide range of package-delivery services as senders, including FedEx and DHL, but the latest outbreak employs a wider variety of messages such as, “Dear client, recipient’s address is wrong”, “Dear User, Delivery Confirmation: FAILED”, and “Dear Client, We are not able to delivery [sic] the postal package”, according to the Commtouch blog.

All the messages then instruct the recipient to open the attachment that contains the malware, claiming it is an invoice or a form that needs to be filled out. “This time we see differences in the style of the emails – there is far more variation in the automatically-generated subjects, body and attachment names. Last time all the attachments were “UPS.exe” – this time there are many variations,” says Avi Turiel, director of product marketing at Commtouch in an email.

The attackers will evaluate the success of the attack by finding out how many recipients activated the malware, “Based on the infections vs. malware sent out they will probably try and figure out what they could improve in the next attack,” he says.

Apple Admits To Security Issues

Apple has finally acknowledge and has promised an update for Mac OS X that will find and remove the MacDefender fake security software, and warn uninfected users when they download the infectious program.

The announcement — part of a new support document that the company posted late Tuesday — was the company’s first public recognition of the threat posed by what security experts call “scareware” or “rogueware.”

Apple has taken criticism for not publicly responding to the MacDefender threat.

“In the coming days, Apple will deliver a Mac OS X software update that will automatically find and remove Mac Defender malware and its known variants,” Apple said in the document. “The update will also help protect users by providing an explicit warning if they download this malware.”

Apple also outlined steps that users with infected Macs can take to remove the scareware.

Andrew Storms, director of security operations with nCircle Security, was surprised that Apple said it would embed a malware cleaning tool in Mac OS X.
