[INVALID]WinSCP 6.5.5 portable confusion - are there two versions? Does one of them contain malware?
Were there two versions of WinSCP 6.5.5 portable released?
Somehow I ended up with the version which does not match what you distribute now.
Have I been hacked? Have you been hacked?
Here's what I have, WinSCP.exe, version 6.5.5.16453, size 24,060,560 bytes.
The current download, the same version and size, but
Its VirusTotal check.
I've attached it here. Just to make things clear: I downloaded it from the official SourceForge pages.
Edit: spent an hour with ChatGPT discussing this weird build. Looks like it mostly matches the official except for the signature and certain relocations. I'm still freaked out.

Final edit: disregard this topic. The new binary is the result of uncompressing the UPX-compressed file. It looks like it no longer produces bit-perfect decompression results.
