Skype users targeted by ransomware worm

A malicious worm spreading through Skype instant messages threatens to take control of a victim's machine and hold its contents for ransom. They receive one of the following messages: "lol is this your new profile pic? h__p://goo.gl/{BLOCKED}5q1sx?img=username" or "moin, kaum zu glauben was für schöne fotos von dir auf deinem profil h__p://goo.gl/{BLOCKED}5q1sx?img=username".

The link points to a file hosted on Hotfile.com labeled as "Skype_todaysupdate.zip," containing the malicious payload. If users download the file, it will open a backdoor allowing hackers to hijack their PCs.

"On installation, this worm appears to initiate large scale click-fraud activity on each compromised machine, recruiting it into a botnet," says Trend Micro's Rik Ferguson.

"The infection will subsequently install a ransomware variant locking the user out of their machine, informing them that their files have been encrypted and that they will be subsequently deleted unless the unfortunate victim surrenders a $200 fine within 48 hours."

Skype said in a statement:

"Skype takes the user experience very seriously, particularly when it comes to security. We are aware of this malicious activity and are working quickly to mitigate its impact. "We strongly recommend upgrading to the newest Skype version and applying updated security features on your computer. "Additionally, following links - even when from your contacts - that look strange or are unexpected is not advisable."
