Bitcoin News said the largest aggregation address tied to the COLDCARD attacker, which currently holds 562 BTC, received a dust transaction carrying an OP_RETURN message that offered money-laundering services in exchange for a 10% cut. The sender spent 0.002347 BTC in total, sent only 1,590 sats to the attacker-linked address, and returned the rest to a change address, putting the cost of the ad at about $1.3. The OP_RETURN message included a Telegram account for the person behind the solicitation, but Bitcoin News did not disclose that handle and said there is no evidence the advertised account is genuine. The stolen bitcoin has not moved, according to the report. Bitcoin News said the transaction shows that someone reached out to the attacker, not that the attacker has already started laundering the funds.
