day one of giving the fly unlimited white monster and cigs until its neurons are trained to win me bug bounties
Wintermute lost 20M OP to an address that didn't exist
They gave Optimism their ETH Safe address. The guys from OP decided to send the funds to their OP Safe address...
> the Safe came from the old factory's createProxy, plain CREATE
> CREATE addresses come from deployer + nonce, nothing about the code or the owners
> the factory itself was deployed with a pre EIP-155 TX, no chain id, replayable on any chain
> attacker replays the factory on Optimism, calls createProxy until the nonce matches, same address, his owners
The ultimate G that did this
- sold 1M
- sent 1M to Vitalik
- returned 17M two days later
- kept 1M

Been learning about ZK-SNARKs lately! The core ideas behind modern hash-based schemes are surprisingly accessible & elegant 🧙♂️
Partly to teach myself, I wrote a post explaining them from scratch for people like me without a deep math background:

ALERT! Our system detected a suspicious transaction targeting @x100global on Ethereum, resulting in an estimated loss of $4.75M. The root cause stems from a governance design flaw that allowed the attacker to acquire two of three Senate seats using flash-loan-funded X tokens and immediately approve and execute a malicious treasury proposal within the same transaction.
The attacker purchased X tokens using flash-loaned funds, distributed them to two controlled contracts, and froze them in the Freezer to obtain Senate seats. The attacker then created and supplied liquidity to a PancakeSwap V3 X-USDT pool. Using the captured majority, the attacker executed a proposal directing the Freezer to swap 400,000 X tokens into that pool with the minimum output set to zero, receiving only about 35.68 USDT. Finally, the attacker withdrew the liquidity, sold part of the recovered X tokens through the existing Uniswap V3 X-USDT pool, and repaid the flash loan.

a solidity compiler bug i found and reported is now public
contracts compiled with via-ir and the optimizer on could read a stale storage value.. affects 0.8.19 to 0.8.37, fixed in 0.8.38.
i explained the bug here: hackmd.io/@d4r3d3v1l/optimze…
Replying to @solidity_lang
The bug: when a Yul variable used to compute memory or storage addresses was reassigned, the Yul optimizer did not always notice that its knowledge about those addresses had gone stale.
A load could then be replaced with an outdated value, or a needed store could be removed.

If you are in NY join @magnusweb3 and myself for a fireside chat on CLARITY, Midterm elections and what it all means.
Clarity stalled in the Senate. I would say the question is what institutions build on until Congress acts.
Tomorrow 4:40 PM, Stefan Muehlbauer and I take it on at the @CertiK NYC Open House. Ronghui Gu, IBM and Midnight open at 3:30.

The US Office of the Comptroller of the Currency (OCC) issued a final rule on the GENIUS Act for stablecoins yesterday. It is 700 pages long!
I created a checklist with readiness scoring for those who don't want to read all 700 pages.
