Evmos successfully avoided a crisis: security researcher found a fatal vulnerability and received a $150,000 bounty!

On the Evmos blockchain of the Cosmos Network, a Web3 security researcher, alias "jayjonah.eth", discovered a potentially fatal vulnerability through in-depth research that could cause Evmos and all decentralized applications (DApps) built on it to stop running. This discovery saved Evmos from potentially significant losses, and the researcher received a $150,000 bounty.

While analyzing the Cosmos documentation, the researcher discovered the hidden dangers of "module accounts", pointing out that if these accounts received funds that did not comply with the expected rules, it could cause the network to crash. After testing, he confirmed this theory, and the results showed that the Evmos blockchain completely stopped generating blocks, seriously affecting the normal operation of the ecosystem. Fortunately, the Evmos team quickly took repair measures before the vulnerability was made public.

"jayjonah.eth" emphasized the importance of document review in his blog and encouraged more security researchers to read project documents carefully, pointing out that "the most critical vulnerabilities are often very simple." This not only mitigates the risk of cyberattacks for Evmos, but also once again proves the importance of the bug bounty program as an effective tool for protecting project assets.

Also in September, the Shezmu protocol recovered nearly $5 million in stolen cryptocurrency through successful negotiations with hackers, showing the power of bug bounties.
