Crypto Wallets Exposed "Mnemonic Phrase Vulnerabilities" (4 Already Fixed)

Too Long; Didn't Read

Popular cryptocurrency wallet providers MetaMask and Phantom (Solana ecosystem) disclosed on the 16th that they have recently patched a security flaw. The vulnerability stems from a problem in Javascript that may cause the mnemonic to be stored in memory for a period of time, allowing an attacker to obtain the.mnemonic from an unencrypted hard drive, thereby controlling the victim user's encrypted assets and NFTs. Wallet providers have notified at least ten other browsers and extension-based wallet providers, including MetaMask, Phantom and Brave.
