Good news, our November challenge is finally out!

We’ve recovered this piece of malware which is running on a botnet in the wild. Can you take down the botnet by removing the malware from all the bots within it?

You can download the malware from hereĀ

The flag format is ‘sigint{1337_sp34k_phr4se}’.

Note: don’t run this malware outside of a virtual machine, it won’t trash your computer but you will become part of our botnet.

If you’ve got any questions or think something is broken then please do send us a message and we will do our best to help. Good luck!
