Hackers broke into the node package manager (NPM) account of a well-known software developer and added malware to popular JavaScript libraries, targeting crypto wallets.
Hackers have only managed to steal $50 worth of crypto from a massive supply chain hack affecting JavaScript software libraries, industry security researchers say.
Crypto intelligence platform Security Alliance shared the findings on Monday after hackers broke into the node package manager (NPM) account of a well-known software developer and added malware to popular JavaScript libraries that have already been downloaded over 1 billion times, putting countless crypto projects at risk. Ethereum and Solana wallets were specifically targeted, Security Alliance said.
Fortunately, less than $50 has been stolen from the crypto space so far, the security firm said, identifying Ethereum wallet address “0xFc4a48” as what it believes to be the only malicious address so far. It added on X:
“Picture this: you compromise the account of a NPM developer whose packages are downloaded more than 2 billion times per week. You could have unfettered access to millions of developer workstations. Untold riches await you. The world is your oyster. You profit less than 50 USD.”
The $50 figure was, however, bumped up from 5 cents a few hours earlier, suggesting the potential damage may still be unfolding.
The 5 cents stolen were in Ether (ETH) while another $20 worth of a memecoin was compromised, Security Alliance said. Etherscan data shows the malicious address has received Brett (BRETT), Andy (ANDY), Dork Lord (DORK), Ethervista (VISTA), and Gondola (GONDOLA) memecoins so far.

The breach targeted packages such as chalk, strip-ansi, and color-convert — small utilities buried deep in the dependency trees in countless projects. Even devs who never installed them directly could be exposed.
NPM is like an app store for developers — a central library where they share and download small code packages to build JavaScript projects.
The attackers appear to have planted a crypto-clipper, a type of malware that silently replaces wallet addresses during transactions to divert funds.
Ledger’s chief technology officer Charles Guillemet was among many who have urged crypto users to proceed with caution when confirming onchain transactions.
This is a developing story, and further information will be added as it becomes available.
