  • HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer “auth”

  • HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Run\ “Safron” = %Desktop%\\# DECRYPT MY FILES # .txt

The samples were actually distributed via a pay-per install software source which generates income for the criminal operators. Such schemes use freeware software that are disguisesd as premium commercial software that requires a payment to be downloaded, installed or used.

The Karma ransomware is distributed mainly across English-speaking countries targeting both individual users and businesses. The usual infection methods are employed – spam email campaigns, Trojans and browser hijackers that serve the dangerous binary files.
