The post Hyperliquid User Loses $21 Million Due to Private Key Compromise, Experts Say appeared on BitcoinEthereumNews.com. In brief A user on Hyperliquid was hacked for $21 million after their private keys appear to have been leaked. Private keys allow a wallet owner to sign a transaction, meaning anyone in possession of it has control over the wallet. Blockchain security experts say that private keys can be compromised via phishing sites, malware-infected devices, and poor personal security habits. A hacker stole $21 million worth of crypto from a Hyperliquid user after their private key was leaked, on-chain security firm PeckShield said. The attacker has since bridged the stolen funds to Ethereum, including $17.75 million worth of the DAI stablecoin. In crypto, a private key is a series of numbers and letters that proves control of a wallet and allows a user to sign transactions. This means that when this key is compromised, a malicious actor is able to sign transactions from the wallet—allowing them to send themselves funds. “It seems the $21 million theft stemmed from a private key leak, since the attacker had full wallet control and there was no smart contract exploit involved. That’s a clear sign the key itself was compromised,” Deddy Lavid, CEO of blockchain analytics platform Cyvers, told Decrypt. At the time of writing, it is unclear how the victim’s private keys were exposed to the hacker, but it is a painful reminder as to why personal security is so important.  “Private keys often get leaked through phishing sites, malware-infected devices, or seed phrases stored unencrypted in the cloud or screenshots,” Lavid explained. “To stay safe, users should use hardware wallets, avoid typing or pasting keys online, and store backups offline and encrypted.” The hack follows a rise in popularity in perpetual futures-focused decentralized exchanges, in which Hyperliquid has asserted itself as the industry leader for this year.
