.Pak files Detection

scans BattleEye the MD5 checksum of the *pak file for detection?

anyone knows that?

I assume your asking if they scan the hash, yes they do and there is no way around it.

If yours is not the original one and BattLEye checks at some point ( and it does very quickly ) you are banned, the days of editing the pak files are over.

Yes they do scan the hash.
