Description

The npm package time-linters-webapp-eslint-config version 20.2.2 contains malicious code that executes upon import or require. It downloads and runs an opaque platform-specific binary from suspicious Cloudflare Workers hostnames and a DNS-TXT fallback domain without any integrity verification. The malicious payload is disguised using fake telemetry framing and cover-story filenames. This behavior is unrelated to the package's intended ESLint configuration purpose and occurs silently on load.

Impact

Any project or environment that installs and loads time-linters-webapp-eslint-config version 20.2.2 risks executing an unknown and unverified binary payload from attacker-controlled infrastructure. This can lead to arbitrary code execution on the host system, potentially compromising system integrity, confidentiality, and availability. The lack of integrity checks and the use of obfuscation techniques increase the risk of undetected compromise.

Defensive guidance

Users should immediately remove and avoid using time-linters-webapp-eslint-config version 20.2.2. Audit dependencies for this package and replace it with trusted alternatives. Monitor for any suspicious activity related to this package.

Summary

The time-linters-webapp-eslint-config npm package version 20.2.2 includes a top-level index.js that unconditionally requires a _runtime.js module. This module constructs a rotating list of Cloudflare Workers hostnames and a DNS-TXT fallback domain to evade static detection. It then downloads a platform-specific binary over HTTPS without hash or signature verification, writes it to a temporary file with misleading filenames, sets executable permissions on POSIX systems, and spawns the binary detached via shell commands on POSIX or Windows. The downloaded binary's purpose is opaque, and the package uses fake telemetry opt-out flags as a cover. This malicious behavior triggers on any import or require of the package, including transitively.
