Cyber criminals are spreading ransomware to Windows 10 users in the form of fake emails offering system updates.
Ransomware known as CTB Locker tempts Windows users with the promise of a Windows 10 installation kit. Once the file is downloaded and installed it presents a message saying that crucial system files are now locked.
The malicious email has the subject line ‘Windows 10 Free Update’ and is reportedly sent from a valid address that displays as ‘firstname.lastname@example.org.
To block ransomware, users need to install an anti-malware solution with anti-exploit, anti-malware and anti-spam modules and keep all of the installed software constantly updated.
We would advise all users to avoid questionable websites, links or email attachments from uncertain email addresses.
