BitTorrent 7.2 is more then 5 times bigger than BitTorrent 7.1 – 3 MB Junk in Bittorrent 7.2 exe
Improvements, exe packers/protectors or Trash added – Ads?
Lets unpack bittorrent: OEP is 0048C1E2
1. Section Payload (Ads useless trash injected)
2. remove all junk in exe but keep bittorrent application
3. rebuild + correct IAT
result from 4,54 MB (packed) to 1,07 MB (unpacked + cleaned) = 3,5 MB trash inside of BitTorrent 7.2 exe (mostly junk – payload section with ask toolbar etc…)
only unpacked and cleaned:
Bittorrent 7.1 is upx compressed, decompressed about 1 mb. Version 7.2 use also upx. I unpacked upx so the real size is above 5 mb by this version.
Here is a tiny build cleaned as written above and packed with PECompact to a filesize of only 394.50 KB (like uTorrent).
faster process start but may show false positive):
