CrushedKiwi on 2022-08-30 22:13: I don't know what really happened but after I get disappointed and closed the x32dbg suddenly find Unpacked.exe and it was an easy xor and find the password. s1 = b"E2*2{0\"z" flag = "" for i in s1: flag += chr(i ^ s1[0]) print(flag) flag = "" for i in s2: flag += chr(i ^ s2[0]) print(flag)

CrushedKiwi on 2022-08-30 22:18: it seems when I just debug the file and enter any password it drops the Unpacked.exe which is easy to REV

JMac2 on 2022-09-01 12:12: I have looked at this crackme and I did not get any dropped .exe file. Where did it put the executable ?

Krekkmiii on 2022-09-23 16:11: poor JMac2 been trying to solve this crackme since may 27th lol

JMac2 on 2022-09-25 05:59: Embarrassment and shame are character building lol
