What to do

Remove bigops-api-mobile from every project, lockfile and image that pulls it in. Treat any host that installed it as compromised: rotate the credentials, tokens and keys it could read, from a clean machine.

Description

The npm package bigops-api-mobile version 35.6.2 contains malicious code that downloads and executes arbitrary code from obfuscated Cloudflare Workers endpoints without integrity verification. This results in full host compromise upon installation or execution of the package. The malicious payload uses multiple fallback mechanisms including a DNS-TXT covert channel to ensure execution. Removal of the package does not guarantee full remediation as the system may already be fully compromised.

Impact

Any system with this package installed or running is considered fully compromised, allowing attackers full control over the host. All secrets and keys stored on the compromised system should be considered exposed and must be rotated from a secure environment. Removal of the package alone does not guarantee removal of all malicious artifacts or backdoors introduced by the payload.

Defensive guidance

Immediate removal of the bigops-api-mobile package version 35.6.2 is recommended. All secrets and credentials stored on the affected system should be rotated from a different, trusted machine. Due to the full host compromise risk, a full system reinstallation or forensic analysis is advised to ensure complete remediation.

Summary

The bigops-api-mobile npm package version 35.6.2 includes a malicious payload that, upon require(), loads a runtime script which dynamically reconstructs obfuscated Cloudflare Workers subdomains and downloads executable code over HTTPS without hash or signature verification. The downloaded code is saved to disguised temporary files with executable permissions and launched detached via shell commands, enabling full host code execution controlled by the attacker. A DNS-TXT based covert channel fallback reassembles a base64 payload from indexed subdomains if HTTPS delivery fails. Secondary activation paths exist via telemetry.js, which contains similar dropper primitives. The obfuscation techniques defeat static detection, and the lack of publisher verification means the host is fully compromised once the package is installed or run.
