Malicious code in blocks-sahred-atom-mobile-app-bar-action (npm)
The npm package 'blocks-sahred-atom-mobile-app-bar-action' contains malicious code that downloads and executes a binary payload from obfuscated Cloudflare Workers hosts and fallback domains. The package name is a misspelling of 'shared' and masquerades as a mobile SDK. The malicious payload is saved to temporary directories with disguised filenames and executed, potentially giving full control of the affected system to an attacker. Any system with this package installed should be considered fully compromised, and all secrets and keys should be rotated from a clean environment.
AI Analysis
Technical Summary
This malicious npm package, identified as 'blocks-sahred-atom-mobile-app-bar-action' version 35.6.8, exposes a stub class and loads a secondary script that fetches an obfuscated binary payload from multiple Cloudflare Workers endpoints and fallback DNS TXT channels. The payload is base64-chunked, reconstructed, saved to temporary locations with disguised names, permissioned for execution, and then launched detached via shell commands. The command and control hostnames are dynamically assembled at runtime to evade detection. The package's misspelled name and mobile SDK facade are used to deceive users. Installation of this package results in a full system compromise.
Potential Impact
Systems with this package installed are fully compromised, allowing attackers to execute arbitrary code with the privileges of the user running the package. This can lead to unauthorized access, data exfiltration, and persistent control over the affected system. All secrets and keys stored on the compromised system should be considered exposed and must be rotated from a secure environment.
Mitigation Recommendations
No official patch or remediation is available. Immediate removal of the package is recommended; however, removal alone does not guarantee elimination of all malicious components. It is critical to consider the system fully compromised, rotate all secrets and keys from a different, trusted machine, and perform a thorough incident response and system remediation process.
