If you need to securely grant execution privileges, what better way to do it than sexec? This is running on sexec.pwning.xxx:9999 sexec.tar.gz Summary: attacking a small instance of Ring-LWE based cryptosystem with Babai’s Nearest Vector algorithm.
We just got this fancy new cryptographic device and it seems to work great… for the most part. But sometimes the values it gives me are wrong. Maybe you could take a look for me. radioactive.tar.bz2 Summary: fault attack on RSA signature (not RSA-CRT)
Although it seems like The Plague’s messaging service is secure, there are bound to be bugs in any 20th century crypto system. We’ve recovered a version of the block cipher The Plague implemented. Use their online encryptor tool, at 220.127.116.11:8193, to break the cipher and figure out Plague’s secret plans. NOTE: When the service sends …
The Plague is building an army of evil hackers, and they are starting off by teaching them python with this simple service. Maybe if you could get full access to this system, at 18.104.22.168:9990, you would be able to find out more about The Plague’s evil plans. Code: (can be run locally with $ socat …
Our archaeologists recovered a dusty and corrupted old hard drive used by The Plague in his trips into the past. It contains a private key, but this has long since been lost to bitrot. Can you recover the full key from the little information we have recovered?
We found the source code for this robot encryption service, except the key was redacted from it. The service is currently running at 22.214.171.124:4433 Summary: IV predict, byte-by-byte bruteforce
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! Summary: Shamir’s Secret Sharing
