@OpenZeppelin Congratulations, great team! 👏

[Alireza Arjmand @_Allarious]

So proud of this team 🔥

[Cantina 🪐 @cantinasecurity]

We spent years finding vulnerabilities before attackers did. That was the easy part.

Teams already know what's broken. Nobody has the bandwidth to close it.

Today we raised $16.5M to make Cantina the security workforce for your security workforce. https://t.co/GWF2OICZsr

Always a pleasure working with the @arkisxyz team. Excited to see where this goes.

[Arkis @arkisxyz]

Arkis has partnered with @spearbit, the security research firm behind reviews for @Morpho, @coinbase and @liquid_col to create the first fully verifiable, tamper-proof digital provenance for institutional smart contracts.
@spearbit's sign-off is required before any release reaches production, and anyone can verify it independently. https://t.co/wedM8FCGkE

[Alireza Arjmand @_Allarious]

@0xOrion0x Not currently, will keep you posted if anything comes up though

[Alireza Arjmand @_Allarious]

We're hiring for Lead web3 security researchers at Cantina, if you've done audits before send us your application and let's chat! 🙂

@mellodadp Sure! Sent a DM 😁

[Alireza Arjmand @_Allarious]

We’re putting real engineering time into getting this right. If you want to follow progress or get early access, the waitlist is in the original post.

[Cantina 🪐 @cantinasecurity]

The AI security tool we’re building surfaced a high-severity vulnerability in Cosmos’ bug bounty, confirmed on HackerOne. We’re designing it for signal > noise so organizations can prioritize real risk.

The waitlist is now open.

Down for the challenge? Let's work together, anon 😎👀

[Cantina 🪐 @cantinasecurity]

We’re hiring 🪐

Cantina is looking for Security Researchers to join our network and work on deeply technical smart contract and protocol audits.

The ideal candidate is:
•Experienced in Solidity and EVM vulnerabilities
•Curious, rigorous, and collaborative

[Alireza Arjmand @_Allarious]

Full report isn't out yet, but it seems like the attacker can replace target address with its own. So check that your computer isn't affected. https://t.co/bkddZOPHBv

[Alireza Arjmand @_Allarious]

Looks like one of the npm package maintainers got compromised, check your projects and stay safe out there!

[Anton Livaja @antonlivaja]

Npm package maintainer got pwned and now a bunch of packages he maintains (including debug-js) have malware in them. Check your deps immediately:

[Alireza Arjmand @_Allarious]

After 2.5 years of auditing at @OpenZeppelin I'll be joining @spearbit starting next week! Really appreciate all the opportunities I got at OZ and looking forward to the future 👀

Great write-ups by @patrickd_de! Highly recommended for anyone looking to enhance their knowledge in the field!

[patrickd @patrickd_de]

I normally find retweeting my own stuff pretty cringe, but it seems like lot's of you haven't seen these yet and I honestly think they're severely underrated :P
