One of the original Bitcoin core developers, Luke Dashjr, claimed on Twitter that attackers had managed to compromise multiple wallets — which he described as both hot and cold wallets — to steal all of his Bitcoins. Dashjr originally blamed the attack on a PGP key compromise, but later said the PGP compromise was only a part of a much broader hack where attackers also bypassed two-factor authentication and got access to what he had believed to be a cold wallet.
Dashjr complained on Twitter about having trouble getting in contact with the FBI about the theft. Some joked about the irony of a Bitcoin maximalist running to the FBI when his coins were stolen.
There are some questions about the veracity of Dashjr's claims, given his supposed security practices, the extent of the breach, and some of his odd comments on Twitter.
