UPX is an executable compression system that is open source. I want you to take the current latest version of UPX's source code (from here: [login to view URL]) and alter the code in a way that any executable compressed with the customized version cannot be unpacked with 'upx -d' command, and that the final executable no longer contains the "UPX" string marker. That is, change it to something else.
I can pay more, if your customized version cannot be automatically detected as "UPX compressed" by virustotal dot com.
The customized version must naturally still be able to compress a given Windows exe file (32 bits) and that compressed exe file must still run normally.
The purpose of this task is to create a slightly altered version of UPX to make it a bit more difficult for people to unpack the executable as an anti-piracy measure. I understand this step does not deter any determined cracker but if this makes them need to work five more minutes, it's worth it.
Hi, I have experience in UPX custom version, packer/unpackers, IDA, x64dbg, PE structure. VT detects from the file you want to obfuscate, if it is marked as "BAD file" UPX custom sometimes is not enough. Write me Daha Fazla
