Hattrick has been achieved! 3 Cosmos SDK contest wins in a row 🥇
Years of grinding Cosmos audits paid off. Success does not (always) come overnight, guys.
Shoutout to @code4rena, the amazing contest sponsors, and everyone involved!
Especially the amazingly skilled @3DOCsec, who volunteered to partner up with me. Thanks!
The results of the $80,000 Initia Cosmos competitive audit are in!
Congratulations to everyone who submitted valid findings, especially to @bernd_eth for securing over half of the total prize pool along with 7 solo high-risk findings submitted!
Much respect to @initia for their unwavering commitment to the highest security outcomes.

Heads up for anyone writing Rust today.
The Rust Security Response Team just disclosed a supply chain attack. The popular arrayref crate was republished to pull in a malicious dependency that downloaded a payload through its build script.
arrayref isn't obscure. If you or your dependencies pulled it recently, you'll want to check now.
The malicious versions to look for:
> arrayref 0.3.10
> internment 0.8.7
> append-only-vec 0.1.9
> proc-macro1, plus typosquats: proc-macro-en, aovine, arone, aronenao, tinymember
All deleted from crates.io, and the maintainer's account is locked. The team believes the author's credentials were compromised rather than the author acting maliciously.
Full advisory, including the one-line command to scan your local cargo cache:

200 🐐s securing this space! I'm proud to be selected as one of them.
Let's get to work - duty calls.
The final 100 ETHSecurity Badge holders are in!
That brings us to 200 security experts, guiding how TheDAO allocates its funds and also coordinating behind the scenes to make Ethereum safer.
Big thanks to everyone who engaged with the process and helped shape it, and to @bonfiresai for building the tooling that made it possible.

It is @SecurityOak who brought me into this industry, gave me a chance to prove myself, and trusted my abilities from the very first audit. Thank you!
It's great to see how things have grown and matured, and I'm proud to work alongside 50+ chad auditors.
Cheers to the future!
We’ve had a glowup!

Don't trust your validators, always verify!
One of my 17 HMs in the recent @zetachain contest on @sherlockdefi made it into the spotlight 🎉
Welcome back to Sherlock's Vulnerability Spotlight, where we highlight an impactful vulnerability uncovered during a Sherlock audit.
This week, we have Deposit Spoofing.
It was uncovered by @0xalpharush & @bernd_eth on the @zetachain Cross-Chain Contest. 🧵
