Java drive-by generator used in recent attack
Posted on 09.05.2012
A malware delivery campaign that doubles its infections efforts to really make sure the users get compromised has been recently spotted by F-Secure researchers.

One of them landed on a website that poses as a "Gmail Attachment Viewer", which tries to make the visitor run the offered application.

The pop-up warning from Windows identifies it as a "Microsoft" app but says that the app's digital signature cannot be verified and that the app's publisher is "Unknown".

If the user does choose to run the app, he is faced with a Cisco Foundation invitation to attend a conference, while the download and the quiet installation of a malicious binary is performed in the background.

Curiously enough, the message contains an embedded link that, if clicked, again tries to download the same malware.

The researcher does not mention how she ended up on the site in question in the first place, and what type of malware is actually pushed onto the user, but points out that the infection is generated using iJava Drive-by Generator:


"The generator allows the attacker to use random names or specify their own preference for both the Java file and the dropped Windows binary," the researcher explains, and points out that the helpful tool also indicates to the attackers how many infections has the delivered malware effected.
