Security researchers from Socket have discovered ten malicious npm packages that infiltrated the Node Package Manager ecosystem, mimicking legitimate tools and downloaded nearly 10,000 times. These typosquatted packages contain malware that bypasses application-level security to target system keyrings, allowing the harvesting of decrypted credentials and access to critical resources like corporate emails and databases. Users who installed these packages are advised to treat their systems as compromised, disconnect from the internet, revoke exposed credentials, wipe and rebuild the infected system, change passwords, audit npm dependencies, review logs for suspicious activity, and enable multi-factor authentication.
