| HMX0101 Author 27. Jan 2006 | try this, easy stuff... |
|---|---|
| Ank83 27. Jan 2006 | hint to unpack it ... |
| HMX0101 Author 27. Jan 2006 | The ESI register goto the real packer |
| hadicol 27. Jan 2006 | ok i fixed the PE header a little and got it dumped. anyone know why my patches aren't being saved in the patch window? |
| HMX0101 Author 27. Jan 2006 | I think that can be a trick ;) |
| Kerberos 28. Jan 2006 | Ufff ... I was totally lost but finally I've found a way how to unpack it :) Thx for this CrackMe and a little ESI hint :) |
| HMX0101 Author 28. Jan 2006 | Thanks guys, for trying :) |
| hadicol 29. Jan 2006 | Ok I wrote a keygen! Is that MD5 or SHA? :o |
| hadicol 29. Jan 2006 | ;) if I write a solution will you tell me why patches didnt hold in Olly's Patches window? |
| HMX0101 Author 29. Jan 2006 | the algorithm not is MD5 or SHA1, not is cryptographic :) and the patches maybe a trick of scrambled/encrypt with different keys used by my protector ;) |
| HMX0101 Author 29. Jan 2006 | The serial is very easy to sniff, a hint for the serial is the string format: XXXX-XXXX-XXXX-XXXX |
| Kerberos 29. Jan 2006 | Serial key generating method is really simple ... main part of this CME is unpacking and bypassing anti-debugging tricks. I've found 2 AntiD tricks, ale both of them will close you OllyDBG :) |
| HMX0101 Author 29. Jan 2006 | the crackme has 1 antidebugging in the unpacking and 4 in the crackme :) |
| hadicol 29. Jan 2006 | oh i was being sarcastic about the md5 ;) ya its pretty simple keygen to see if you know how delphi passes args (with the registers EAX, ECX, EDX, and then stack) |
| EvOlUtIoN 21. Jul 2006 | we doesn't need to study algo for keygen this...it is too simple |
| hardcoder 22. Jul 2006 | Packer somehow looks like upx.yeah, keygenning is simple |
