Malicious code in cjdfswifuem3 (npm)
The npm package 'cjdfswifuem3' version 1.0.0 is a malicious package that does not execute code upon installation but hosts an HTML page impersonating a Cloudflare Turnstile challenge. This page uses obfuscated JavaScript to redirect visitors to a phishing URL, abusing the npm registry as a distribution channel for phishing content rather than a supply-chain attack. The threat targets end users who access the hosted HTML via phishing links, not the package installers. There is no evidence of installer-side code execution or credential theft during installation.
AI Analysis
Technical Summary
The 'cjdfswifuem3' npm package version 1.0.0 contains no executable JavaScript modules; its package.json points to an index.html file that cannot be required or imported. This HTML page simulates a Cloudflare Turnstile challenge and then executes obfuscated JavaScript to redirect visitors to a phishing URL, forwarding query parameters. The npm registry is abused solely as a hosting platform for this phishing lure page. No lifecycle scripts or importable code exist to compromise the installer. The threat is limited to end users who visit the phishing page, not to developers installing the package.
Potential Impact
There is no impact on users who install or import the package, as no code execution or credential access occurs during installation. The impact is on end users who visit the phishing page hosted by the package, potentially exposing them to phishing attacks via redirection to malicious URLs. The package itself does not compromise the installer's system. The ghsa-malware source's claim that any computer with this package installed should be considered fully compromised is inconsistent with the technical analysis and appears incorrect under the described threat model.
Mitigation Recommendations
Since the package does not execute code on installation and targets end users via phishing links, the primary mitigation is to remove the package from the npm registry to prevent abuse as a phishing hosting platform. Users should avoid visiting URLs associated with this package. No patch or update is applicable as this is registry abuse rather than a software vulnerability. No action is required for developers who have installed the package but have not visited the hosted HTML page.
