The npm account of developer ‘qix’ was compromised through phishing, allowing attackers to publish malicious versions of fundamental JavaScript packages including chalk, strip-ansi, and color-convert. The crypto-clipper malware operates through two vectors: intercepting network traffic to replace wallet addresses in HTTP requests, or hijacking transactions directly when crypto wallets are detected. The malware uses sophisticated address swapping with visually similar addresses to evade detection. While specifically targeting cryptocurrency transactions, the attack vector affects all JavaScript environments including web applications, servers, and mobile apps. Major projects like Uniswap and Blockstream have confirmed they are not affected, but users are advised to verify all transactions carefully, especially when using software wallets.
