I’m excited to share that t.me/rata0x and I have been collaborating on the Coinbase data leak for the past few months, assisting U.S. Law Enforcement. Today, we informed the affected victims who worked with us that Coinbase will be compensating them. If you were impacted, please reach out to us—we’ll help you submit your case to @coinbase for full recovery. Huge thanks to Coinbase for taking steps to make their customers whole!

COINBASE DATA LEAK! Coinbase : Cyber criminals bribed and recruited a group of rogue overseas support agents to steal Coinbase customer data to facilitate social engineering attacks. These insiders abused their access to customer support systems to steal the account data for a small subset of customers. We will reimburse customers who were tricked into sending funds to the attacker. We’re cooperating closely with law enforcement to pursue the harshest penalties possible and will not pay the $20 million ransom demand we received. Instead we are establishing a $20 million reward fund for information leading to the arrest and conviction of the criminals responsible for this attack.

Reminder guys: now with PECTRA ethereum upgrade, you only need to sign a message to get completely drained! Before, you actually had to sign the TX. Be very careful of what you sign now - even an offchain message!

Three Good Multisig Operations Tips! 1) You can create multisig with Safe, and sign transactions off-chain and send them using any other wallet that doesn't control multisig at all. So, you could use Safe contract alternatively to any ERC2771 smart contracts (like Openzeppelin Defender is). 2) How to choose a better number of signers? Pick a M-of-N multisig where M is less than N, such as 2-of-3. Give yourself some leeway, a 2-of-2 requires all your backups to work perfectly. 3) Implement Web3 Front-end monitoring, use a tool by @koda (link below)! P.S. That’s an awesome app: pilot.gnosisguild.org

A victim lost $510,294 due to copying the wrong address from transaction history! Victim: 0x0d534863a71d5e68d5c919a4c2ef47c3a7a792c0 Fake address: 0x4049Ebf479Fa49924e120490d119f0827cAa9aeC Legitimate address: 0x40491fe2bA81621475c894Ebe8bcad56C7da9aec How transaction history poisoning works: 1. Scammer sends fake/dust transfer with similar address; 2. Their fake address appears in your history; 3. You copy address from history thinking it's legitimate; 4. Funds get sent to scammer instead. How to stay protected: 1. Always double-check the addresses you're sending funds to; 2. Never copy addresses from transaction histories; 3. Use a wallet that supports whitelisting or bookmarks.
