Gameover malware targets accounts on employment websites

In addition to CareerBuilder, new variants of the Trojan program target Monster.com, researchers from F-Secure said

A new variant of the Gameover computer Trojan is targeting job seekers and recruiters by attempting to steal log-in credentials for Monster.com and CareerBuilder.com accounts.

Gameover is one of several Trojan programs that are based on the infamous Zeus banking malware, whose source code was leaked on the Internet in 2011. Like Zeus, Gameover can steal log-in credentials and other sensitive information by injecting rogue Web forms into legitimate websites when accessed from infected computers.

The ability to inject content into browsing sessions in real time has traditionally been used by computer Trojans to steal online banking credentials and financial information. However, cybercriminals are increasingly using this technique to compromise other types of accounts as well.

For example, in February, researchers from security firm Adallom found a Zeus variant that stole Salesforce.com log-in credentials and scraped business data from the compromised accounts.

The latest development involves a new Gameover variant that contains a configuration file to target Monster.com accounts, one of the largest employment websites in the world, security researchers from antivirus firm F-Secure said Tuesday in a blog post.

"A computer infected with Gameover ZeuS will inject a new 'Sign In' button [into the Monster.com sign-in page], but the page looks otherwise identical," they said.

After the victims authenticate through the rogue Web form the malware injects a second page that asks them to select and answer three security questions out of 18. The answers to these questions expose additional personal information and potentially enable attackers to bypass the identity verification process.

Targeting Monster.com is a new development, but the Gameover malware had already been targeting CareerBuilder.com, another large employment website, for some time.

Recruiters with accounts on employment websites should be wary of irregularities on log-in pages, especially if those accounts are tied to bank accounts and spending budgets, the F-Secure researchers said. "It wouldn't be a bad idea for sites such as Monster to introduce two factor authentication beyond mere security questions."

The authors of the Gameover Trojan program have been particularly active recently. In early February researchers from security firm Malcovery Security reported that a new variant of Gameover was being distributed as an encrypted .enc file in order to bypass network-level defenses. Later that month researchers from Sophos detected a Gameover variant with a kernel-level rootkit component that protected its files and processes, making it harder to remove.

Unlike most other Zeus spinoffs, Gameover is also using peer-to-peer technology for command-and-control instead of traditional hosted servers, which improves its resilience to takedown efforts by security researchers.

Educating from the epicentre - Why distributors are the pulse checkers of the channel

Educating from the epicentre - Why distributors are the pulse checkers of the channel

​As the channel changes and industry voices deepen, the need for clarity and insight heightens. Market misconceptions talk of an “under pressure” distribution space, with competitors in that fateful “race for relevance” across New Zealand. Amidst the cliched assumptions however, distribution is once again showing its strength, as a force to be listened to, rather than questioned. Traditionally, the role was born out of a need for vendors and resellers to find one another, acting as a bridge between the testing lab and the marketplace. Yet despite new technologies and business approaches shaking the channel to its very core, distributors remain tied to the epicentre - providing the voice of reason amidst a seismic industry shift. In looking across both sides of the vendor and partner fences, the middle concept of the three-tier chain remains centrally placed to understand the metrics of two differing worlds, as the continual pulse checkers of the local channel. This exclusive Reseller News Roundtable, in association with Dicker Data and rhipe, examined the pivotal role of distribution in understanding the health of the channel, educating from the epicentre as the market transforms at a rapid rate.
