Cursedzx Posted May 4, 2019 Share Posted May 4, 2019 (edited) after few months, i decided to try again and i have finally unpacked it! steps: 1. decrypted strings for parameter. 2. converted str that is actually an int value. 3. resolved all sizeOfs. 4. converted reference proxy calli to normal calls and removed the proxy calls. 5. Removed some Cflow. 6. calculated the integer values that uses xor to get the value. 7. decrypted all the strings. 8. cleaned cflows and the rest acrack-me_obfuscated_Unpacked.exend also renamed.
