UCSB iCTF 2017 - yacs
Yet another... cat service?!
yacs is a tool to store and later retrieve text snippets. If you store program source code there, it can even compile it for you! So handy. Of course, everything is protected using state-of-the-art user authorization and password hashing. It's a big C++ compiled binary which uses a local SQLite database file for data storage. Here's a normal create/list paste workflow: ___...
RuCTF Finals 2017
We participated in the RuCTF Finals 2017 and finished 12th.
Last Sunday we had the pleasure to participate in the RuCTF Finals 2017 in Yekaterinburg, Russia. After a long day of attacking other teams and defending our own services we managed to secure the 12th place out of 23 active teams. The services we had to work on were really interesting and quite diverse. But a really nice touch to the game was the actual hardware separation of services. Instead of providing a virtual machine...

EKOPARTY CTF 2016 - FBI 300
Bitcoin as OP_RETURN Dropbox
The description of the challenge was as follows: There has been some strange transactions on this blockchain! Let's do some research. After downloading and extracting the data (fbi300_64635d9aa64b20d0.7z) is was clear that we where looking at at a .bitcoin folder of a bitcoin-core client hat was started in regtest mode. As a first guess we used bitcoin-abe to read and analyze the blockchain. (https://github.com/bitcoin-abe/bitcoin-abe). Since bitcoin-abe looks out-of-the-box in the default bitcoin directory ($HOME/.bitcoin/blcoks/*) the only thing we...

We participated in the iCTF 2015 and finished 8th.
Last Friday we participated in this year's iCTF. For the first time the services were not written by the organizers, but each team had to provide a service themselves in order to participate. Although this meant that there were fewer teams this year, still 30 teams took up the challenge in total. The organizers also got some angry comments for this setup, and they liked one of them so much that their unofficial theme...

Finished 3rd at iCTF2014
In this years iCTF2014-2015, themed "hacking at scale", we reached the 3rd place out of more than 80 participating universities.
Last Friday we participated in the ictf2014 and reached the 3rd place out of more than 80 participating universities. This years theme was "hacking at scale" with 42 services to pwn, most of which had been reused from previous iCTF's. We constantly improved our score during the CTF until we were at the second place about one hour before the end with only Team Bushwhackers in front of us. However, SpamAndHex did an incredible finish,...
