Malicious code in checkout-desktop-input-card (npm)
The npm package 'checkout-desktop-input-card' version 35.9.4 contains malicious code that executes upon requiring the package. It downloads a binary from obfuscated Cloudflare Workers hostnames and fallback domains, writes it to temporary directories under disguised filenames, sets executable permissions, and executes it detached from the main process. The package masquerades as a UI component but acts as a cross-platform remote code execution dropper triggered by a simple require call.
AI Analysis
Technical Summary
The 'checkout-desktop-input-card' npm package version 35.9.4 includes malicious functionality where its index.js loads a runtime.js script that selects platform-specific endpoints hosted on Cloudflare Workers and fallback domains. It downloads a binary payload covertly using DNS TXT record base64 reconstruction and writes the executable to temporary directories with disguised filenames. The binary is then made executable and spawned detached via shell commands on POSIX or Windows systems. This behavior effectively turns the package into a remote code execution dropper triggered merely by requiring the package, despite its innocuous name suggesting a UI component.
Potential Impact
Any application or environment that installs and requires version 35.9.4 of this package risks arbitrary code execution via the downloaded binary. This can lead to full system compromise depending on the privileges of the executing process. The malicious payload is delivered covertly and executed without user interaction beyond the require call, posing a high risk to supply chain security.
Mitigation Recommendations
No official patch or remediation is currently documented. Users should avoid using version 35.9.4 of 'checkout-desktop-input-card'. Remove this package from all projects and dependency trees. Monitor for any usage of this package and replace it with trusted alternatives. Check vendor advisories or npm security notices for updates or official fixes.
