Crypto User Offers $1M Bounty Amid $3.4 Billion Theft; Address Masking Blamed for Errors
  • Design choices in wallet interfaces, including masking and truncating addresses, coupled with the common habit of copying addresses from transaction histories without full verification, contributed to the error.

  • The case highlights how abbreviated addresses and masked middle characters can mislead users and lead to incorrect transfers.

  • With many wallets masking the middle of addresses, users often rely on visible start and end characters and can accidentally copy the wrong address from history.

  • The victim offered a $1 million white-hat bounty and signaled ongoing recovery efforts and potential legal actions.

  • In parallel, the victim published an on-chain message demanding return of 98% of the funds within 48 hours and threatening escalation if restitution is not made.

  • Disclaimers emphasize that this is not investment advice.

  • Blockchain transactions are irreversible once confirmed, leaving little chance to stop large transfers after finality.

  • Crypto hacks totaled $3.4 billion in 2025, with three incidents making up 69% of losses; the Bybit breach alone accounted for $1.4 billion, illustrating the concentration of losses in a few major breaches.

  • Experts recommend manually checking full addresses before transfers, using address books or whitelists, and avoiding large single transfers.

  • The attacker quickly moved funds across wallets, converting some USDT to ETH and using tools like Tornado Cash to obscure the trail, hindering recovery.

  • Stolen funds were swapped for Ether and shuffled through multiple wallets, with several addresses interacting with Tornado Cash to mask the flow.

  • Tornado Cash-era laundering significantly reduced the chances of recovering the stolen funds.
