Jaff
Description
(Fortinet) Like many ransomware variants, Jaff ransomware commonly arrives as a pdf attachment. Once you open the attachment, it displays a one-line document along with a pop-up message asking whether you want to open an embedded.
After downloading the binary file, Jaff ransomware starts decrypting part of the malware code. It uses a simple code redirection routine as an anti-analysis trick to stretch the time it requires to analyze the actual malicious code. In between code execution, it uses garbage code that is not relevant to the malware execution.
