Symptoms

Typically, users will receive a notification (ransom note) that a threat actor has taken control of the system or the files. The note usually explains how to pay the ransom, how much it’s for, and how long users have to pay before their files are deleted.

Type and source of infection

Ransomware is a threat that prevents users from accessing their system or personal files and demands ransom payment in order to regain access.

The most common infection vectors for ransomware are:

Malicious spam (malspam) emails that include booby-trapped PDF or Office documents
Exploit kits via malvertising (drive-by download)
