exe2powershell is used to convert EXE to BAT files, the previously well known tool for this was exe2bat, this is a version for modern Windows.
It depends on which bat-to-exe converter got used, but it will most likely be in one of the folders that have '.tmp' at the end of the name. – SomethingDark Jul 22 '19 at 21:55 @yuvalchen This was a few years ago and I found the EXE in an old cloud storage, There is nothing in my Temp folder – user7152599 Jul 23 '19 at 0:30. 4sysops - The online community for SysAdmins and DevOps. Michael Pietroforte Fri, Dec 3 2010. Mon, Aug 11 2014. The four ways to convert a batch file to an EXE file are IEXPRESS.EXE the free Bat To Exe Converter tool, the Sysadmin Geek's BAT to EXE converter script and commercial BAT to EXE compilers.
This will convert any binary file (*.exe) to a BAT file, the resulting BAT file contains only echo commands followed by a PowerShell command to re-create the original binary file.
This kind of tool can be useful during a pen-test when you want to trigger a shell without any upload feature. With echo and PowerShell the auditor is able to upload any binary file to the target system.
This version is modernized from exe2bat to work with current Windows versions as exe2bat had some limitations:
- Needs
debug.exeavailable on the target computer (16-bit application which was removed in Windows 7 x64 but available in Windows 7 x86) - Limits input exe size to 64kB
exe2powershell replaces the need of debug.exe by using a PowerShell command line which is available on all Windows since Windows 7 / 2008 and there is no more limitation in input exe size.
