Microsoft Warns About Black Friday and Cyber Monday Ransomware Campaigns
Microsoft experts have uncovered that computer criminals are abusing the craze around the Black Friday and Cyber Monday sales by sending spam email messages to unsuspecting users which distribute dangerous ransomware.
The hackers have used the names of Amazon and other online retailers to fool the users into infecting themselves with ransomware. A sample email message excerpt contains the following text:

The messages contain malicious ZIP archive attachments which appear to contain order information. In reality these files contain dangerous payloads, in many cases ransomware and Trojans that pose a serious threat to the computer owners.
Several of these messages have been used to distribute the Locky threat.
The online retailers have already taken measures against such attacks by posting comprehensive guides and articles that help their customers to distinguish between legitimate and counterfeit emails.
