Odaily Planet Daily News, January 10 - A Bitcoin and Litecoin holder provided a 12-word mnemonic phrase to attackers impersonating Trezor support personnel, resulting in the transfer of approximately $282 million in assets, including about $139 million in Bitcoin and $153 million in Litecoin.
Blockchain forensics firm ZeroShadow stated that the incident stemmed from a social engineering attack, not a compromise of wallet software or private key infrastructure. The stolen funds were split within minutes via the THORChain cross-chain bridge and converted into Monero through instant exchange services.
ZeroShadow's monitoring team flagged and froze approximately $700,000 in funds within 20 minutes. Under the BIP39 standard, a 12-word mnemonic phrase contains approximately 128 bits of entropy, while a 24-word mnemonic phrase contains 256 bits of entropy.
Chainalysis estimates that up to 23% of all mined Bitcoin is permanently inaccessible due to lost keys, involving millions of BTC, with causes including forgotten mnemonic phrases, damaged backups, and lack of inheritance planning.
