2016-11-23: Hacking Livestream #5 - solving picoCTF 2013 (part 1)

Tomorrow (sorry for the late notice) at 7pm CET (GMT+1) I'll do another livestream on CTFs - this time I'll try to show how to solve several picoCTF 2013 challenges in the time frame of the stream (2 hours). PicoCTF 2013 was an entry-level CTF created by the well known team Plaid Parliament of Pwning - so expect the challenges to range from 10 points (or 30 seconds) to 100 points (several minutes). The first stream will actually be a really good opportunity for folks wondering what are CTFs about and how to start with them to have some of their questions answered (at least I think so). Anyway, the details:

As always, the stream will be recorded and will be available immediately after the stream on my channel.

See you tomorrow!

2017-01-09: Garść newsów: DS top 2, Sekurak/Offline #3

DS top2, p4 top5Pierwsze newsy z nowego roku:

  • Dragon Sector zakończył sezon 2016 na drugim miejscu - czyli udało nam się powtórzyć rezultat z 2015 :). Trochę więcej rozpisałem się kilka dni temu na moim FB, więc wspomnę jedynie, że na piątym miejscu sezon zakończył inny polski zespół - p4 - gratulacje!
  • Wyszedł Sekurak/Offline #3, czyli darmowy e-zin o bezpieczeństwie (głównie webowym) prowadzony przez ekipę serwisu sekurak.pl. Link do linków ;)
Na ten moment tyle. "Słoniem w pokoju", jak to lubią mawiać nasi zachodni znajomi, jest pytanie kiedy kolejny stream - prawdopodobnie dopiero w następnym tygodniu, ale jeszcze zobaczymy jak wyjdzie.

Five newest or recently updated notes (these are unfinished posts, code snippets, links or commands I find useful but always forget, and other notes that just don't fit on the blog):

The full list of vulnerabilities discovered by me (including collaborative work) can be found here (please note that the list might be out of date).

The Google Application Security / Research site might also contain some of my findings.

EN Coding (selected posts)
EN Tools and libraries
  • PiXieServ is a simplified PXE (network boot) server for Windows and Linux-based OS, created for testing of very small home-made OS. See also the post about it.
  • ExcpHook, a system-wide exception monitor for Windows XP 32-bit. Useful if you're fuzzing something that doesn't like having a debugger attached.
  • Ent is an entropy measuring tool for reverse engineering reconnaissance (see also a post explaining how to use it).
  • HiperDrop is a simple command line process memory dumper for Windows, with a few different work modes.
  • asmloader - this little app executes headerless machine code (compiled assembly code). It's meant to be an aid in learning/teaching and playing with assembly, as well as the right tool when you just need to execute some machine code.
  • NetSock is a simple socket/networking lib/wrapper for C++ I've wrote back in 2003 and update from time to time - I use it for most of my network-enabled projects.
