\nColdcard Bitcoin Theft Continues, Now Estimated Over $114 Million In Total Stolen<\/a><\/p>\n

<\/div>\n

Hackers continue to drain Coldcard Bitcoin wallets, with the total amount stolen now estimated to be standing at over $114 million.\u00a0<\/p>\n

A fourth wave of attacks likely started on Sunday evening, according<\/a> to Galaxy Research\u2019s Alex Thorn. Posting at around 7:50pm in New York, he revealed then that 388.9 Bitcoins worth over $29 million had been moved in new transactions that were highly likely to be part of the theft.\u00a0<\/p>\n

Hackers started by taking over $35 million in Bitcoin from wallets on Thursday. Coinkite, which makes Coldcard, said that a firmware bug in Coldcard Mk3 devices \u2014 starting with version 4.0.1 in March 2021 \u2014 caused seed generation to fall back to a weak software Pseudorandom Number Generator instead of the hardware true random number generator, allowing hackers to essentially guess investor seedphrases.\u00a0<\/p>\n

The theft continued throughout the weekend while Coinkite and other Bitcoiners urged Coldcard users to immediately move their funds.<\/p>\n

Posting on X on Monday, Trezor\u2019s Josef T\u011btek wrote that the biggest transaction in the ongoing theft so far was 51 Bitcoins.\u00a0<\/p>\n

The biggest drained address (so far) is 51 BTC. Damn. Imagine owning 50+ btc in cold storage and losing it all. Must be absolutely crushing. pic.twitter.com\/qu6CiQOjeV<\/a><\/p>\n

Coinkite has since admitted all of its models were vulnerable following more thefts. Engineers have warned that all Bitcoin addresses related to Coldcard could be at risk<\/a> eventually.\u00a0<\/p>\n

The company said Sunday that it was asking \u201chard questions about our company.\u201d<\/p>\n

\u201cThe last three days have been some of the hardest in this company\u2019s history, and for a lot of the people reading this, they\u2019ve been something much worse,\u201d Coinkite said.\u00a0<\/p>\n

\u201cMoney that took years to save, gone. Trust that took years to build, broken. That impact is real, and for some, the damage is permanent.\u201d<\/p>\n

The company added that it had destroyed its remaining Coldcard inventory manufactured with the vulnerable firmware, and shipments of the product have been halted.\u00a0<\/p>\n

Coinkite makes a number of Bitcoin products, including the popular cold storage hardware wallets.<\/p>\n

Engineers at payments company Block investigated the hack and reported that the hackers used a top blockchain services provider for help in moving the funds, and that they\u2019ve contacted the provider and federal authorities with their findings.\u00a0<\/p>\n
