A Bitcoin and Litecoin investor reportedly handed over a 12-word recovery phrase to attackers posing as Trezor support, leading to the theft of about $282 million in crypto assets. The haul included roughly $139 million in Bitcoin and $153 million in Litecoin, ME News reported on Aug. 2 (UTC+8).
Blockchain forensics firm ZeroShadow said the loss stemmed from a social engineering scheme rather than any breach of the wallet software or private-key infrastructure. Investigators said the stolen funds were divided within minutes using the THORChain cross-chain bridge, then routed through instant exchange services and converted into Monero.
ZeroShadow added that its monitoring team identified and froze about $700,000 within 20 minutes.
The incident has renewed attention on seed-phrase security. Under the BIP39 standard, a 12-word mnemonic carries about 128 bits of entropy, compared with 256 bits for a 24-word phrase. Chainalysis estimates as much as 23% of all mined Bitcoin—millions of BTC—may be permanently inaccessible due to lost keys tied to forgotten mnemonic phrases, damaged backups, or inadequate inheritance planning.
