Coldcard Hacker Wallet Becomes "Blockchain Message Wall," Holding Over $36 Million in Stolen BTC

According to CoinDesk, since the Coldcard hardware wallet vulnerability incident erupted on July 30, the wallet address associated with the hackers (bc1qq85v2c926eg6pgxhwp6q7lf6cnsz80qs3fcu9r) has received multiple Bitcoin transfers accompanied by text messages. The wallet currently holds approximately $36 million in stolen assets, and confirmed losses from this incident have exceeded $100 million. The aforementioned information was written on-chain via Bitcoin's OP_RETURN function and permanently stored on the blockchain. The content covers victims' pleas for compensation (such as "You stole, please return some," "Return 80% of my 5 BTC"), solicitations for money laundering services ("I launder BTC, taking a 10% commission," with Telegram contact information included), and even fundraising requests completely unrelated to the incident, varying in nature.
