Win 10 Malware

Just days after Microsoft released its latest operating system, hackers have begun targeting soon-to-be Windows 10 users with an emerging kind of malware.

Cisco security researchers are warning users against opening email attachments purporting to be from the software giant. The "ransomware" malware, which encrypts files until a ransom is paid, is being sent as part of an email spam campaign.

In a blog post, Cisco researcher Nick Biasini said the attackers are "impersonating Microsoft in an attempt to exploit their user base for monetary gain."

The emails claims its attachment includes an installer that allows users to get the new operating system sooner.

"The fact that users have to virtually wait in line to receive this update, makes them even more likely to fall victim to this campaign," said Biasini.

Once a user downloads and opens the attached executable file, the malware payload opens, encrypting data on the affected computer, and locking the owner out.
