10 Trending Cyberthreat Attacks In 2013


Ransomware Rising

Ransomware, which locks a victim's infected machine and demands payment for the unlock code, has been steadily increasing, McAfee said. The number of new, unique malware samples this quarter is greater than 320,000, more than twice as many as last quarter, the company said.

Ransomware attacks are growing in popularity over fake antivirus software because attackers have figured out that they can use anonymous payment services to keep security researchers and law enforcement from tracking them down, according to McAfee.
