Resurgence of DJVU/STOP Ransomware Strain in the Wild (Part 1/2)

This blog provides a technical analysis of the DJVU/STOP ransomware family, describing a multi-stage infection chain in which a loader allocates executable memory, stages primary and secondary shellcode, resolves Win32 APIs dynamically, and performs process hollowing to inject a ransomware crypter that encrypts files and drops ransom notes; the report also notes widespread distribution via cracked software and adware bundles and promises a follow-up analyzing the crypter payload.
