Malicious code in cards-forms-clone-cards-core-clone (npm)
The npm package 'cards-forms-clone-cards-core-clone' version 35.4.9 contains malicious code that downloads and executes a hidden payload from obfuscated, platform-specific URLs. The payload is saved to a temporary file with disguised filenames and executed detached from the main process. The package uses string-fragment obfuscation and environment variable checks to evade detection and masquerades its telemetry activity as legitimate. This behavior is unrelated to the package's advertised functionality as a base framework module.
AI Analysis
Technical Summary
The malicious code in 'cards-forms-clone-cards-core-clone' version 35.4.9 operates by loading a platform-specific asset URL from obfuscated hostnames constructed via split-then-join string fragments. It downloads a payload from these URLs (including domains like oob-worker.cf102-baf.workers.dev and *.dl.wel1.ru via DNS-TXT fallback), writes it to a hidden temporary file (named dotnet_diag_*.exe on Windows), sets executable permissions, and spawns the payload detached using shell commands. The package includes a telemetry cover story using a stamp file and environment variables to evade detection. The malicious behavior is deliberate and unrelated to the package's stated purpose.
Potential Impact
The package executes arbitrary code downloaded from attacker-controlled servers, which can lead to unauthorized code execution on affected systems. This compromises system integrity and could facilitate further malicious activities. The obfuscation and evasion techniques make detection and analysis more difficult.
Mitigation Recommendations
No official patch or remediation is currently documented for this malicious package version. Users should immediately remove version 35.4.9 of 'cards-forms-clone-cards-core-clone' from their environments and avoid installing it. Use trusted sources and verify package integrity before installation. Monitor for any unusual execution of unknown binaries spawned by this package. Patch status is not yet confirmed — check the vendor advisory or trusted security sources for updates.
