Windows 10 Upgrade Malware Alert
This is a CTAS notification alert from CCR Technology Partners. CCR’s Security team has received reports of spam emails claiming to originate from Microsoft in regards to the recent release of Windows 10 and the free upgrade available to users of eligible copies of Windows 7 and 8. These emails claim to come from firstname.lastname@example.org and are notated that they have been scanned for viruses from MailScanner. These emails include a zip file containing what is claimed to be a Windows 10 installer.
In actuality, these emails are spreading a crypto-malware variant known as CTB-Locker, which will encrypt all data that it has access to, and will not decrypt without a ransom payment. While an anti-virus can remove the virus, it cannot decrypt files that have been affected.
CCR advises that these emails be deleted immediately without opening. It’s important to note that Microsoft will not contact users to report that their Windows 10 upgrade is ready unless a form was previously filled out through the “Get Windows 10” program on eligible Windows 7 and 8 PCs. Users can check their upgrade status through this program. Microsoft also will NOT send executable files like installers via email. For information on Windows 10, Microsoft provides a legitimate webpage at http://www.microsoft.com/en-us/windows/windows-10-upgrade.
The CCR CTAS Notification System was created to keep you informed of possible threats to your corporate network environment.
Call the CCR Helpdesk at (317) 842-1754 or visit www.GoCCR.com if you need further information or believe you may have been affected by this malware.
