Alphapo

Wallet Stolen

Estimated loss

$60.00M

VERDICT —OUT OF SCOPE

Root cause is private-key / signer compromise — the on-chain contract behaved exactly as written. No pre-deployment source audit or bytecode review reaches the key-custody perimeter; this is operational-security territory (HSM/MPC hygiene, key rotation, hot-wallet isolation). Bytecode would show nothing wrong.

Forensic narrative

Cryptocurrency payment service provider Alphapo's hot wallet stolen, $23 million lost. Alphapo client HypeDrop has disabled withdrawals. The stolen funds were first exchanged for ETH on Ethereum and then cross-chained to the Avalanche and BTC networks. Alphapo processes payments for many gaming services such as HypeDrop, Bovada, and Ignition. It is unclear how many bitcoins were stolen from Alphapo. On July 25, on-chain analyst ZachXBT tweeted that in the Alphapo hot wallet theft incident, an additional $37 million stolen on TRON and BTC due to this hack has been found. Now the total stolen from Alphapo has increased to $60 million. The hack was likely carried out by Lazarus. Attack method (per SlowMist): Wallet Stolen. Reported loss: $ 60,000,000.
