The Problem With Self-Extraction Files

The use of self-extracting files or SFX files that was reported by CrowdStrike in a blog post. The trick here is that the actual SFX file does not contain any malware, it just contains a little command at the end which can then be used to download and/or run additional malware on the system.SFX files are also fairly flexible, they're like different decryption unpacking stops that can be used with SFX.
