LCX Hack

REPORTED LOSS $7.9M
Medium Hot-wallet compromise; initial access unknown ethereum

What happened

On January 8, 2022, approximately $7.94 million in ETH and tokens was stolen from one LCX Ethereum hot wallet. LCX said its other wallets and customer personal data were unaffected. It paused deposits and withdrawals and committed its own funds to covering affected balances.

Technical Root Cause

Unauthorized access to a single hot wallet enabled the transfers. LCX did not publicly describe the initial access method in its incident report, so a specific private-key theft or software vulnerability is unconfirmed.

How it happened

  2. LCX paused deposits and withdrawals and contacted partners and authorities.
  3. Monerium disabled movement of approximately 611,000 EURe. Freezing these tokens did not by itself establish their return.
