Solana validator breach steals $135,000, funds laundered via Tornado Cash

A coordinated attack on Solana ‘s validator ecosystem resulted in the theft of approximately $135,000 in cryptocurrencies after multiple validator credentials were compromised and funds were quickly moved to the mixing protocol Tornado Cash. The incident took place from October 26 to 27, allowing the attacker to control operational keys associated with several key participants in the Solana network, including Solflare, Blockdaemon, Astraeus, an unidentified validator, and an inactive validator linked to Slow Ventures. Bitquery, a blockchain analytics firm, investigated the attack and reported that the attacker gained access to operational validator keys. This allowed the unauthorized transfer of crypto assets held within validator accounts.
