New 0day vulnerability in Windows exploited in-the-wild

    Specialists at iSIGHT Partners today announced a new vulnerability CVE-2014-4114 in Windows 7+, which they discovered a month earlier. According to company analysts, the vulnerability was exploited by a cybercriminal group whose traces lead to Russia. Exploitation of the vulnerability is possible using a specially crafted MS PowerPoint document, which contains embedded OLE objects. The component of the Windows subsystem, which is responsible for processing embedded objects, contains a vulnerability that allows you to download the .INF file from a remote server and install it on the system.

    The exploit is a PowerPoint document that contains two objects, oleObject1.bin and oleObject2.bin. Each of these files contains a link to an external IP address. One of them is used to download the .INF file, which will be used to install the malicious program, and the second contains a link to the malicious program itself - the BlackEnergy Lite dropper (Win32 / Rootkit.BlackEnergy). This dropper will be installed into the system using the downloaded .INF file. We recently wrote about a malicious campaign to distribute BlackEnergy Lite to one of the hacker groups, whose roots also go to Russia. In both cases, NATO countries become targets.
