Cybercriminals Are Distributing Malware with Fake Flash Player Served from SkyDrive

A large number of websites from Germany are being abused in this attack

F-Secure researchers have spotted a large number of Trojan.JS.Blacole.Gen infections over the past days. A closer analysis has revealed an interesting malware distribution campaign.

According to experts, cybercriminals have compromised a number of websites, 40% of which from Germany. They’ve taken the scripts from these sites and added malicious code.

When users visit the infected sites, they get redirected to a page that instructs them to update their Flash Player in order to gain access to the content.

If the victim clicks on one of the Download Now links, a file called flashplayer.exe is downloaded from a SkyDrive account. When the user executes this file, a window which reads “Installing latest Flash Player” is displayed.

In the meantime, another piece of malware is downloaded from the same SkyDrive account.
