At its core, Craxs RAT is a remote access trojan that evolved from Spymax RAT (also known as SpyNote). When the Spymax RAT source code leaked in 2020, a developer known as "EVLF" (believed to be based in Syria) modified it to create a new cyber threat — Craxs RAT. Since then, the RAT has spread through social media platforms like Telegram, infecting users through phishing links and malicious APK files.
