Deep dive into Python's VM: Story of LOAD_CONST bug - Diary of a reverse-engineer
http://doar-e.github.io/blog/2014/04/17/deep-dive-into-pythons-vm-story-of-load_const-bug
Diary of a reverse-engineer. Because we like to play with weird things. Deep Dive Into Python's VM: Story of LOAD CONST Bug. A year ago, I’ve written a Python script to leverage a bug in Python’s virtual machine: the idea was to fully control the Python virtual processor and after that to instrument the VM to execute native codes. The python27 abuse vm to execute x86 code.py. But before going further, I just would like to clarify a couple of things:. A 0day or a new bug ; can be a cool CTF trick though.

One of the main idea was for example to build a home-made 32 bits adder to replace the. You can then feed the output directly to clang to generate ...

Adventures of an electronics and software guy. PlaidCTF 2015 “RE GEX” Write-up. This challenge came with a simple Python TCP server and a monstrous. In a separate file. It consists of multiple sub-patterns (2563 to be exact), separated by OR operators. To get the flag, the input supplied must NOT match any of these sub-patterns. If you break up the large regex expression, you see something like this:. The 3 conditions listed up front give you a hint to the requirements: must be made up of the letters.

Adventures of an electronics and software guy. Magnetic Stripes & Stuff. Apparently you can visually read magnetic stripes, if you can somehow see the magnetization patterns encoded on the stripe. I recently found out that this is indeed possible. The density is not that high and following methods will allow us to visualize the encoding. You could use a “magnetic developer”. Solution and learn how each bit is encoded. Or you could use iron (oxide) filings. In this video linked from the Hackaday article.

Brain Damage
O parte din gandurile mele. Orbi Trecem cu totii prin lume fara sa privim in stanga si-n dreapta, ca niste turme de oi, indobitociti de noi insine. De ce nu mai vedem lumina? De ce nu mai distingem nimic inafara de plumbul ce ne inconjoara? Casele, odinioara albe si ingrijite, zac acum parasite, jigarite, intre blocuri asemeni pietrelor funerare, iar cerul senin este acum prafuit. Cenusie devine si pielea noastra cand trecem in nefiinta. Totul este ca scrumul unei tigari proaste.
