🔒 594 bitcoin drained in fifteen minutes: what we know so far At 01:36 UTC on 30 July, an automated operation swept 500 single-sig addresses across four consecutive blocks of the Bitcoin blockchain, draining 594.5 BTC - approximately 38 million dollars - before consolidating 562 BTC into a new address by 01:51 UTC. Atlas21's analysis of https://t.co/ytZi3G47SA data shows each of the 500 transactions targeted one distinct address, with a median loss of 0.41 BTC per victim. No target held less than 0.15 BTC, suggesting the attacker filtered by minimum balance. The entire operation cost roughly 0.044 BTC in fees. Evidence points to weak private keys generated at birth. Notably, no multisig wallet and no Taproot address was among the victims. The first public alarm came from a Reddit user reporting a drained Coldcard wallet whose seed had never touched a computer. Within hours, prominent figures including @KLoaec, @lopp and @Rob1Ham were publicly flagging the incident as confirmed and serious. https://t.co/vk9XKsJ7eB
