New GandCrab Variants, Varied Payloads Delivered Via Spam Campaign
Security researchers found an ongoing spam campaign aimed at infecting as many systems as possible through simultaneous configurations and infection payloads. New variations of GandCrab ransomware have successfully infected a large number of servers in India, Chile, Peru, the United States, and the Philippines since its discovery in January 2018. With varying infection methods, spam mail attacks have surged in the past couple of days through exploit kits.

The malware leaves a ransom note with a link leading its victims to a site that requires a ToR browser to access. Victims are instructed to pay $400 in Dash — a cryptocurrency considered more difficult to trace and easier to process —for the decrypt key. The attackers double the ransom when it's not paid within the stated period.
Ransomware threats and cybercriminals are getting more creative when it comes to profiting from their victims. Trend Micro recommends that affected victims avoid paying the ransom as there is no assurance that the files will be recovered.
