Results

The 2016 NSA Codebreaker Challenge has concluded. Thank you to everyone that participated and congratulations to each student that was able to make progress in the challenge! We hope that each participant was able to improve his/her reverse engineering abilities while also getting a realistic look at some of the work involved in carrying out the NSA's mission.

Also, we especially congratulate the 15 individuals that made it through all six tasks in the challenge! None of the tasks were trivial to solve, but task 6 in particular required demonstrating an exceptional ability to analyze unfamiliar code, defeat several anti-reverse engineering tactics, and ultimately craft an exploit leveraging vulnerabilities similar to those that exist in real-world applications. Excellent work!

Overall, there were:

  • 3325 students participating from 481 educational institutions
  • 954 students that solved Task 1
  • 751 students that solved Task 2
  • 492 students that solved Task 3
  • 379 students that solved Task 4
  • 119 students that solved Task 5
  • 15 students that solved Task 6

There were several students from universities outside the U.S. that participated in the challenge as well - move the map around to find those too! (Note - participating in the challenge required a valid .edu email address.)

Challenge Backstory

Terrorists have recently developed a new type of remotely controlled Improvised Explosive Device (IED), making it harder for the U.S. Armed Forces to detect and ultimately prevent roadside bomb attacks against troops deployed overseas. The National Security Agency (NSA), in accordance with its support to military operations mission, has been asked to develop capabilities for use against this new threat. This will consist of six tasks of increasing difficulty, with the ultimate goals of being able to disarm the IEDs remotely and permanently render them inoperable without the risk of civilian casualties.

Task 1 Progress
Backstory:

A military organization captured a laptop of a known explosives expert within a terrorist organization. Further analysis revealed that the laptop contained a debug version of the remote client interface that the individual used to communicate with the IEDs. To help detect other client programs in use, we are cataloging binary signatures and basic network signatures for every version of the IED software we find. To support these efforts, your task is to compute the SHA256 hash of the client binary and identify the source and destination TCP ports that it uses when connecting to an IED.

Solution:

Will be revealed next semester! (The solution submission page is still active to allow students who want to finish the challenge a chance to do so.)

Task 2 Progress
Backstory:

Based on the signatures you provided, we were able to collect network communications that we believe contains traffic to an IED that is about to be detonated. Unfortunately, there appears to be a lot of unrelated network traffic in the collected data since other programs use the same port. Using the provided packet capture file (PCAP), we need your help to create more specific signatures for identifying network communications with the IED. This would be a huge first step in detecting when an IED has been armed, for example, which would allow us to alert troops in the region around where the signal was collected. For this task, your goals are to identify the version string sent by the client software when initiating a connection to the IED and to determine the IP address of the undetonated IED from the packet capture.

Intelligence suggests that the version strings are 11 characters long and look something like x.x-xxxxxxx

Solution:

Will be revealed next semester! (The solution submission page is still active to allow students who want to finish the challenge a chance to do so.)

Task 3 Progress
Backstory:

Thanks to your hard work we were able to eventually geolocate the device and work with military partners to retrieve the system for further analysis. It turned out to be a test system that one of the IED developers had been using in lieu of a live device. We provided the system to a team of software reverse engineers and their preliminary assessment is that we have a fully functional copy of the IED software, a key file, and a dummy driver that emulates the various IED states. Analysts believe that this key file contains the information needed to authenticate to a real IED (somewhere in the field) and send commands to it. Presumably this test system was used to validate the software and key file before it was deployed to an actual IED. Since the key file appears to be encrypted, we are going to need your help to figure out a way to decrypt it. This should enable us to disarm the fielded IED that uses this key, though we will still need to figure out exactly how it is being used for authentication (next task). The goal of this task is for you to obtain the decrypted contents of the key file.

Solution:

Will be revealed next semester! (The solution submission page is still active to allow students who want to finish the challenge a chance to do so.)

Task 4 Progress
Backstory:

Now that we have the key file we can work on a disarm capability. Several intelligence reports suggest that terrorists use a secure token (i.e., small hardware device) for generating unique one-time codes for authenticating to the IED when sending commands. We believe these codes change over time and are only valid for a certain time window and for specific device serial numbers. Based on previous signatures you provided, we have located the armed IED that is using the same version of software and key serial number from Task 3 and we need to disarm it ASAP. We do not have the secure token that corresponds to the device, but we still need to be able to authenticate to it with the correct code in order to disarm it. Your objective for this task is to figure out how to generate valid one-time codes and provide one that we can use to disarm the IED. The decrypted key file you provided earlier should help with this part.

Will be revealed next semester! (The solution submission page is still active to allow students who want to finish the challenge a chance to do so.)

Task 5 Progress
Backstory:

We used the code you provided to remotely disarm the IED, which was later found along a route frequented by military transport vehicles. These actions undoubtedly saved the lives of many service members. After disarming the IED, forward-deployed forensic analysts were able to recover several deleted files from the device. The most promising one appears to be the key generator program used to produce device specific keys like the one you recovered in Task 3 and used to generate a one-time code for the IED disarm command in Task 4. If you can find a weakness in how these keys are generated, then we could exploit this to generate valid one-time codes for any IED and remotely disarm it.

Analysts just alerted us of 2 additional IEDs within a few miles radius of military forces. The serial numbers are provided below. We need you to provide valid one-time codes for each one ASAP so we can disarm the devices. Also, recent intelligence suggests that the terrorists are using Linux to generate the keys.

Solution:

Will be revealed next semester! (The solution submission page is still active to allow students who want to finish the challenge a chance to do so.)

Task 6 Progress
Backstory:

Our military partners report that the two IEDs were successfully disarmed, again saving countless lives. Also, thanks to the capability you developed, we can now remotely disarm any IED we find in the field, which is going to make travel through dangerous regions much safer. Agency leadership is very impressed!

Ideally we would like to go one step further and remotely render the IEDs completely inoperable. Given that we may not be able to find and recover disarmed IEDs before the terrorists reclaim them, it would be much better if we could ensure that the IEDs never work again (without actually triggering an explosion and potentially causing civilian causalities.) To that end, we had our hardware reverse engineers study the hardware of a captured IED and develop a hardware simulator to accurately model its operations. This enables more analysts across the enterprise to test and evaluate the system without requiring access to one of the very few captured devices. During development of the hardware simulator, they discovered that if we can somehow cause the hardware to be triggered without being armed then it will “brick” the hardware. This may be our best shot at having a remote disabling capability if we can find a vulnerability to exploit the trigger-before-arm weakness.

From the captured IED we also recovered the hardware driver that contains all the logic for arming/disarming/triggering the actual IED hardware (i.e., unlike the dummy driver that had these functioned stubbed out.) Using this driver with the hardware simulator and IED software provides the most accurate model of the IED hardware and software stack available. The driver appears to contain additional protections that might make analyzing it more difficult, so be on the lookout for code that might be trying to detect dynamic analysis tools.

Your final task is to figure out a way to cause the trigger-before-arm condition and break the hardware. Submit a command file that accomplishes this objective. If you think that you are making progress on this task and would like some limited feedback, feel free to submit the command file you have at any time.

Will be revealed next semester! (The solution submission page is still active to allow students who want to finish the challenge a chance to do so.)
