    This new unpackme using a new custom packer (Smon - I think it is called ) found its way to me. Thought someone here may find it of interest. http://tuts4you.com/download.php?view.1606 I haven't even fired it up in Olly yet so I couldn't tell you what level of difficulty it is... Ted.

    hello. i've started to new thread because some help needed, to be precise it's a request .. team REA has released "BitDefender Update Online Fixer" and they uploaded it into rapidshare, it's ok here .. BUT, that archived file is password protected and team REA haven't give any password .. when you try to extract it asks for a password and because you don't know the correct password you can't fully extract that file .. to get a correct password team REA has made a target to be cracked and only then you can find a correct password .. that target is named "Crackme" and it is inside in that password protected file .. after failed extract you get only that target and *.txt fil…

    Hey all, I was wondering if anyone else has the Asprotect 1.33 unpackme's appearing with corrupted icons (however they seem to work fine). I post a screenshot here to show what I mean. I get this on 2 different computers running 2 different os (w2ksp4+XPsp2) with completely different HW. Kinda ruled out the driver thing this way. Im thinking maybe it's a winrar issue? I dunno... I assume these unpackme's have the same Icon as all other Ted's unpackme's? I downloaded at least 50% of them now, and none of the others appear this way... any ideas? thx

    This is the official RLPack unpackme. Unpacking is considered correct if the unpacked Unpack.exe can unpack crackme.fsg.exe. You can not add ap0x unpacking engine .dll files to unpackme to make it work. You can only use things located inside the challenge archive. Due to the fact that Unpack.exe uses psapi.dll challenge will work only on NT systems. The first one to unpack the official unpackme will get RLPack Full Edition - Personal license!

    I have repeatedly been asked for a next step up from the keygen tut in the newbie series (#36). I finally have found the time to do so. The attached keygenme (see below) is supposed to be accessible for and aimed at newbie level till intermediate (newbie level having understood tut#36, now wanting to try the next level). Rated 2/10. Goal was not to make something difficult, but it will require a good understanding of how things work anyway. I'm awaiting your solutions here and will post mine with commented source (asm) in a couple of days. Success! lena151. lena151__s_KeygenMe_1.rar
