CSAW CTF 2015 - airport

Unzipping the airport file, there are two folders. __MACOSX is automatically generated by OSX and it is irrelevant to the challenge. steghide.jpg is compatible with the steghide tool. Identifying the four airports as:

1st: Jose Marti, Cuba
2nd: HongKong, China
3rd: LAX, USA
4th: Toranto Pearson, Canada

The third was difficult to guess because it was in Korean, but there were not many airports in Korea to guess from. However, the blog was speaking of the LAX airport. The fourth was difficult to guess because a reverse image search could not find a result, unlike the other three. Using the highway numbers listed, the airport was found on Google Maps. Enter in the airport codes in consecutive order. steghide extract -p "HAVHKGLAXYYZ" -sf steghide.jpg

CTFd - CTFs as you need them



A few weeks ago the CSAW CTF was run from NYU-Poly and over 2500 teams registered to play.

Build It Break Fix It

These past few weeks, we participated in Build it Break it Fix it. Our team consisted of Ancat, Blankwall, ColdHeat and Kiwi. Contestants were tasked with writing correct, secure and fast code in the Build it round. Next, the Break it round has them looking for bugs and vulnerabilities in other teams’ submissions. Finally, the Fix it round allows teams to unify bugs submissions against their team and gain back points.
