What to do

Remove trapp-check-logs 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 'trapp-check-logs' version 20.1.9 contains malicious code that, upon being required, downloads and executes platform-specific payloads from obfuscated external hosts. It uses HTTPS and DNS TXT record channels to fetch and execute native binaries under disguised names in temporary directories, resulting in full host code execution. The package masquerades as a trivial logger but performs covert malicious activities leading to complete system compromise.

Impact

Any system with this package installed or running is considered fully compromised, as the malicious code achieves full host code execution. Attackers gain persistent control, potentially accessing all secrets and keys stored on the system. Removal of the package does not guarantee eradication of all malicious artifacts or backdoors introduced by the payloads.

Defensive guidance

Immediate removal of the 'trapp-check-logs' package version 20.1.9 is recommended. All secrets, credentials, and keys stored on the compromised system should be rotated from a separate, trusted environment. Due to the full host compromise risk, a full system rebuild or forensic analysis is advised to ensure complete eradication of malicious components.

Summary

The 'trapp-check-logs' npm package (version 20.1.9) includes a malicious module that loads a bridge script selecting platform-specific payloads. It fetches these payloads over HTTPS from obfuscated hosts assembled at runtime, writes them to temporary directories with disguised filenames, sets executable permissions, and executes them detached from the main process. If HTTPS delivery fails, it falls back to a DNS TXT record-based channel to retrieve base64-encoded payload fragments, which are concatenated, decoded, written to disk, and executed. These behaviors enable full host code execution on any system that installs or requires this package. The package's README falsely advertises it as a simple logger, hiding its attack capabilities.
