How Did Hackers Attack the Bitcoin Wallet Containing Assets Stolen from Mt. Gox?
With blockchain analysis experience, BitMEX Research discovered hackers exploiting the OP_RETURN function to send fake website links, targeting the Bitcoin wallet containing over 8 billion USD stolen from Mt. Gox in 2011. The purpose was to steal the wallet owner's personal information.
OP_RETURN allows on-chain data storage, but hackers turned it into a tool for citing fake pages impersonating the closed Salomon Brothers bank, reporting the wallet as "lost or abandoned" to lure users to access.
This behavior is a sophisticated technique based on blockchain technology to steal user information, clearly showing the increasingly complex attacks in the cryptocurrency space.
