All of the attacks are released for the three platforms (Proxmark3, Flipper Zero, and Chameleon Ultra). Our goal was day 1 support for RFID testing devices.
No worries. I brought it back, DNS propagation just finished. Someone may have killed init or the like, which the software allows root to do. After all, why stop hackers from removing their own access and alerting the NOC team? :)
To whomever murdered init in cold blood: the challenge server is for trying to bypass the security software. If there are too many attempts to simply bring it offline I'll have to keep it powered off for a bit.
Yea, sure. It's a server provided for security researchers. The challenge is to run any program we haven't allowed from the root shell. It's been defeated and patched 3 times over the past 2 years. You can get the list of allowed programs by running `whitebeam --list whitelist | grep Executable`. The details (and bounties) are listed here: https://github.com/WhiteBeamSec/WhiteBeam/blob/master/SECURI...
Unlike the challenge system, we also run some honeypots that record attempts. That way it's easy for both whitehats and blackhats to contribute to the overall QA testing.
I spent a weekend recently comparing GoTTY to similar solutions and GoTTY/ttyd (the C port) are the best projects. Ultimately, I chose ttyd (https://github.com/tsl0922/ttyd), because the main GoTTY project was abandoned 4 years ago. ttyd works very well for my use case, which is sharing a server to test some experimental security software. So far I've gotten thousands of more attempts by running a webserver than sharing SSH credentials. If you'd like to try the server, it's here: http://challenge.whitebeamsec.com/. The font/style are all configurable. The only downside is mobile browsers have difficulty typing.
