Unknown persons gained access to the funds of the owners of wallets based on Solana, stealing millions of dollars.

Initially, the blockchain auditor OtterSec reported the emptying of more than 5,000 wallets in a few hours. The transactions were signed by the owners, which, according to the researcher, suggests compromising the private key.

PeckShield experts have previously estimated a loss of $8 million.

According to Elliptic experts, during the attack, hackers stole more than $5.2 million in SOL tokens, over 300 coins based on Solana, as well as NFT

According to some reports, wallets that have been inactive for more than six months have suffered the most.

The attack affected Trust Wallet, Phantom and Slope wallets. In Solana, users were strongly advised to transfer funds to hardware devices. The head of Binance, Changpeng Zhao, also advised sending assets to cold wallets or centralized exchanges.

At the time of writing, the reason for the hack is unknown. According to preliminary data, the attackers exploited the vulnerability.

According to CoinGecko, against the background of the hacking news, the SOL token sank by 4.6%.

Recall, according to Atlas VPN estimates, hackers stole almost $2 billion from crypto projects in the first half of 2022.
