Happy Friday everyone! We are going to wrap this week of #miniCTF with a report from Avast shedding light on the infection chain and action-on-objectives of the HotRat malware, a variant of the AsyncRAT, and its use of a AutoHotkey script which has been compromising victims who are searching for free software and getting infected instead. Enjoy and Happy Hunting!

***In this miniCTF, I have mapped some of the TTPs to MITRE ATT&CK BUT I have either mislabeled or possibly left some out! It is up to you to correct me and fill in the blanks! Enjoy and good luck!***
