Malicious actors are well-known to take advantage of breaking news, holidays and events to lure unsuspecting victims into downloading malware. The recent release of Microsoft’s highly-anticipated Windows 10 operation system is being used by cybercriminals in phishing campaigns designed to distribute ransomware. Since users have to wait to be notified by Microsoft that they are now eligible to download the new OS, they are more likely to be fooled by this attack.

Talos researchers described the attack in a recent blog post. The attacker is impersonating Microsoft, sending phishing emails from the spoofed email address with the subject line “Windows 10 Free Update.” Clicking on the links in the email will prompt the download of a zip file – – which then executes, installing the ... read more >
