The North Korean hacker group Lazarus has implanted malware for stealing cryptocurrency in a new batch of JavaScript packages
ChainCatcher news, according to Decrypt, the Socket research team has discovered in a new attack that the North Korean hacker group Lazarus is associated with six new malicious npm packages that attempt to deploy backdoors to steal user credentials.Additionally, this malware can extract cryptocurrency data and steal sensitive information from Solana and Exodus crypto wallets. The attacks primarily target files from Google Chrome, Brave, and Firefox browsers, as well as keychain data on macOS, specifically tricking developers into inadvertently installing these malicious packages.The six discovered malicious packages include: is-buffer-validator, yoojae-validator, event-handle-package, array-empty-validator, react-event-dependency, and auth-validator. They lure developers into installation through "typosquatting" (exploiting misspelled names). The APT group has created and maintained GitHub repositories for five of these packages, disguising them as legitimate open-source projects, increasing the risk of developers using the malicious code. These packages have been downloaded over 330 times. Currently, the Socket team has requested the removal of these packages and reported the related GitHub repositories and user accounts.Lazarus is a notorious North Korean hacker group, linked to the recent $1.4 billion Bybit hack, the $41 million Stake hack, the $27 million CoinEx hack, and countless other attacks in the crypto industry.
