Aut2Exe.exe

Aut2Exe.exe is the Windows compiler included with AutoIt v3.3.18.0. It converts AutoIt .au3 scripts into standalone .exe files or .a3x output; compilation is a build step and does not execute the result. The official compiler normally tokenizes, compresses, and encrypts the script representation, and separately supports UPX packing (enabled by default, disabled with /nopack). These are documented compiler behaviors, not evidence that a particular build is malicious or evades security controls. ATT&CK mappings are conditional: T1059.010 applies when an AutoIt script or compiled artifact is executed; T1027.004 applies only if uncompiled source is delivered and then compiled before execution; T1027.002 applies only when packing is used to conceal code.
