Crack all our challenges and show the community that you know your way in security, either as an auditor or a security-minded developer! This CTF was run as a live event during AwesomWasm 2023, for info related to the event check this other file.
Follow us on Twitter at @SecurityOak to receive the latest news on Cosmos security and fresh audit reports.
To get started with the challenges, please go to the main branch. The 10 challenges follow no particular difficulty order, number 1 may not be easier than number 10 and the other way around. Each of them showcase a different security issue or exploitation techniques that we find during our security audits.
