New Flash exploit used to distribute credential-stealing malware

The exploit is embedded into documents distributed as email attachments, researchers from Kaspersky Lab said

A new exploit that prompted Adobe to release an emergency patch for Flash Player was used in targeted attacks that distributed malware designed to steal log-in credentials for email and other online services, according to researchers from antivirus firm Kaspersky Lab.

Adobe released new versions of Flash Player for Windows, Mac and Linux Tuesday in order to address a critical remote code execution vulnerability for which, the company said, an exploit existed in the wild. Kaspersky Lab researchers Alexander Polyakov and Anton Ivanov were credited with reporting the vulnerability.

Eleven SWF (Flash) exploit files that targeted this vulnerability were found, but only one of them contained an executable file as a payload, the Kaspersky Lab researchers said Wednesday in a blog post about their findings.

Some of the other exploits were designed to execute a file from URLs passed to them as a parameter, but the researchers couldn't identify the actual URLs that attackers had used or the files they pointed to.

The SWF files came embedded into .docx files -- Microsoft Word documents -- that had Korean names, but were found on computers in China, the researchers said.

In one case one of the rigged documents was sent as an attachment to an email address registered with 163.com, a Chinese email provider, and was opened from an email client on a computer running Mac OS 10.6.8. However, the exploit was clearly designed to target Windows users.

In two other cases the malicious docx files were found on Windows 7 machines in the cache of Internet browsers, particularly a browser of Chinese origin called Sogou Explorer. This doesn't mean the files hadn't been delivered via email, the Kaspersky researchers said.

The only recovered payload consisted of an executable file that acted as a downloader for additional malware files. The Kaspersky researchers were able to recover two such files.

The first one was a Trojan program designed to steal log-in credentials saved in locally installed programs including Foxmail, OperaMail, Opera, Mozilla Firefox, Safari, IncrediMail, Pidgin and Thunderbird, the Kaspersky researchers said. It also steals data entered into Web forms on a variety of websites, many of which are webmail providers. The list of targeted websites includes Twitter, Facebook, Yahoo, Google, Live.com, AOL.com, Yandex, Mail.ru, gmx.com, fastmail.com, 163.com, lycos.com, mail.com, zoho.com and others.

The second file is a backdoor program that works in conjunction with the first malware, the researchers said. It connects to three command-and-control servers and downloads additional DLL files hidden inside JPEG images.

"We are continuing to follow the bot's activity," the Kaspersky researchers said.

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.
