Arbitrum is about to level up like no other EVM chain. 17 teams have just secured 5M ARB to innovate with Rust on Arbitrum.
Our latest bug report to @optimismFND in their sequencer stack allowed censoring of over 1.3m accounts for an arbitrary period of time. Affected protocols included: @LayerZero_Labs @StargateFinance @HopProtocol @SynapseProtocol @AcrossProtocol + more. 👇 iosiro.com/blog/optimism-…
We reported an issue in the @NethermindEth client that could have led to a consensus failure w/ other Ethereum clients. Bounties were awarded by @ethdotorg and @GnosisDAO. Another big one for @pleasew8t! Details: iosiro.com/blog/nethermin…
We recently disclosed a high risk double-spend vulnerability in @AcrossProtocol's bridge relayer infrastructure. No user funds were at risk! The issue was fixed and awarded with a $90,000 🪲 bounty. Read all the juicy details here: iosiro.com/blog/high-risk…
We helped @AshiqAmien disclose a critical bug in @88mphapp. At least $6.5m of funds could've been stolen by attackers. That's no longer possible. Funds were whitehacked from the contract and returned to users. Bug bounties work. Read the postmortem: medium.com/immunefi/88mph…
We've just open-sourced Baserunner - a tool to explore and exploit Firebase datastores iosiro.com/blog/baserunne…

Wow. @mj0011sec did it. Used heap overflow in Edge, type confusion in kernel, & uninit buffer in VMware for complete virtual machine escape.
