arshi on 2026-11-12 15:14: @liboxin Thanks! I unpacked it statically: the stub’s hash unmasks the page table, which contains the keys needed to decrypt all 42 code pages. Then I recovered the substitution table and rolling-state check to get the serial. The main weakness is that everything needed to unpack it is recoverable from the file, so I didn’t need to tackle the anti-debug checks. As SVz mentioned, lazy mode is also off in this build. The obfuscation inside was more work than the packer itself :)

liboxin on 2026-11-12 15:17: @SVz great man,thanks for your advice,I will improve my packer and will appear in coming version 2
