Researchers have observed ransomware so sophisticated over the last few months that we’ve seen a variant tease researchers with strings of hidden code and another composed entirely of JavaScript.

But not every attacker is technically proficient; researchers are suggesting the ones behind a new strain of ransomware may just be plain lazy. The ransomware Ranscam simply deletes users’ files, even if the victim chooses to pay. Victims are encouraged to pay to unlock their files, which Ranscam claims have been encrypted. “Once your Bitcoin payment is received your computer and files will be returned to normal instantly,” the ransom note claims.
