Topic created on: October 15, 2007 18:51 CDT by bodzcount .

I am just curious what plugins you use for hiding?

Does it make sense to use more hide plugins than ollyadvanced? Have you experinced apps that detect ollyadvanced patches, but dont detect other hide plugins?

Why is there always an option for checkremotedebuggerpresent, isnt it always enough to just patch zwqueryinformationprocess?

if I want to hide I use:
a) soft-ice + IceExt;
b) QEMU + gdb/VMWare + gdb
c) BOCHS (source includes interactive debugger like turbo-debugger)

thats to leet for me ;)

QEMU allows you to debug _any_ OS, using remote gdb protocol, VM Ware (6.0 RC2 and higher) allows the same, but VM Ware ask for money, while QEMU is free. if program works under QEMU/VM Ware, you can debug it. I don't know  protections detecting this type of debugging, so, this is best way to hide. as the most important this is: you can save state of VM at any time, any place and return to debugging whenever you want. you may "replay" it too. it's very useful and saves time.

For me its to unconvenient, because i dont have too much time to spend hacking :) If you want to discover everything, QEMU or BOCHS is a good choice I think.
However I think for the regular unpacking business (execryptor,  etc..), ollydbg + hiding is quicker...Or am I wrong?

never ever debug anything on your production machine! _always_ use VM!

VM Ware is quite fast. well, if you really need full speed - use hardware virtualization emulators. my P-III doesn't support this, so I use VM Ware. yes, I have a dozen modern P-4 boxes, but I LOVE my old P-III and I'm not going to betray it :)

ollydbg + ollyadvanced 1.26 + phantOm v1.15

hide only if you know why you want to hide and know whom you are hiding against otherwise bypass things as you face them (cross the bridge when it comes)
and making a habit of hiding always is certainly not a good habit (think what if the authour was leet and plays havoc after detecting your hidden stature) by being open you get to know each and every tricks that could be played against you
