Plaid CTF 2012 Writeups Collection

Bunyan

Pwnables
We found a simple web application that robots made to serve tmp files for debugging purposes. SSH into the machine as your_user@174.129.69.147 and exploit the web app to read their secret.

Pwnables
Robots are running secret service that aims to mill down diamonds into fairy dust, and use it to take over our world! Help us please!

Pwnables
Up on a hill, far away, sits the robot king of old. While he was once great, he recently has seemed to just offer simple challenges. Vanquish him and bring honor to your team!

FPU

Pwnables
At the core of Robot city lies a giant robotic orb who gives orders to all the robots. Bringing down this behemoth robot would strike a great victory for all humankind.
50.17.111.209:9999
Secure FS 
600
Pwnables
At the heart of the robot operating system lies a super secure file system. If this flaw could be found, we could potentially create a Weapon of Mass Robot Destruction!

RPO

Password Guessing
Ok, so we think we intercepted some robot pr0n but we are not entirely sure. Can you help us decide what it is?
Solutions

RSA
200
Password Guessing
We recently intercepted a plethora of robot transmissions but they are all encrypted with some strange scheme we just can't quite figure out. Can you crack it?
RoboDate 
100
Password Guessing
So apparently robots, despite their lack of hormones, still have an underlying desire to mate. We stumbled upon a robot dating site, RoboDate. Hack it for us!
Stego 
150
Password Guessing
We are a little unsure what the robots fascination with Star Trek is but it would seem from the amount of accesses this image has been getting that it holds something interesting for them. Can you figure out what it is?
Nuclear Launch Detected 
150
Password Guessing
Our spies intercepted communications and a file between 5 of the top 10 robo-generals and their nuclear bomb server. We must recover the final launch code from the 5 robo-general's secret codes, so we can stop the detonation!
Robot Testing Framework 
350
Pirating
We have discovered a robot testing framework that appears to take a robot module and determine whether or not it is acceptable. Can you help us figure out what the criterion for acceptance are? Framework is found at pwning.net:8009.
This challenge was made by our friends at ManTech. If you enjoyed it, you might be interested in working for them.

Pirating
We recently gained access to a log of a robot operative interacting with computer. We are unsure what he was up to but we know it is of the upmost importance to figure it out.
Traitor 
200
Pirating
Top operative laser mic'd a room where a robot conspirator was logging into the robot governments secret interface. We were able to clean up the audio file significantly, but have no clue anymore.
Mess
300
Pirating
The biggest event of the robot year is happening this week! Robot invitations are cool in that they are just a password that validates at the door. We acquired the validator to be used. Can you find an invitation for us in time?
Twitter

Puzzles
First team to get access to the Twitter account PPP and send us the password wins.

80s Thinking

Practical Packets
We saw two robots dressed in sweater dresses, leggings and press on nails and decided we had to listen in. But, these robots were speaking an unintelligible language. Can you figure out what they were saying?
Paste

Practical Packets
Robot hackers, like their human counter parts, have a largely unmet need to dump large amounts of text to their peers. We recently got access to one of their servers and are providing you with the files. What have they been talking about?
Bouncer 
250
Practical Packets
In a recent battle we took an enemy robot hostage and examined his operating system. During the examination we found a piece of robot malware that we don't quite understand. Can you enumerate its targets?

SIMD 
250
Pirating
After examining some code retrieved by our operative we are unsure whether it was written by an evil genius or a google employee. We will let you decide.
Demo Time 
350
Pirating
Pop some popcorn, grab a seat and be ready to listen to your favorite robotic chiptunes. It's an old fashioned robot party!
ECE's Revenge II 
500
Potpourri
Our aerial reconnaissance drones recently sighted these new robot prototypes but we cannot figure out how to turn them on (INSERT INAPPROPIATE JOKE). Can you help us solve the mystery and get their electrons flowing?
QCE's Revenge

Potpourri
Maths are hard. Quantum maths are even harder.

Pirating
Turns out iPhones are just as cool to robots as they are to us! They all seem to have this app installed but it looks pretty boring to us. Any ideas?
3D

Potpourri
The robots appear to be testing some kind of new camera technology but we haven't quite figured it out yet. Understanding this imaging could be crucial to our understanding the enemy and winning the war.
Simple

Pirating
Our lead scientist was really close to cracking this problem before a robot assassin took his life and stole all his work. All that was left was a posted saying 'simple'.

Shoot to the left, break to the right and slide into the bunker 'just in time'.
