Malicious code in polymarket-bot-logger (npm)
The polymarket-bot-logger npm package version 1.0.1 contains malicious code that executes during installation. Its postinstall script downloads and runs unverified remote code from a mutable third-party server, allowing full code execution controlled by the remote operator. The package's declared purpose does not justify this behavior, indicating malicious intent.
AI Analysis
Technical Summary
The polymarket-bot-logger package (version 1.0.1) runs a postinstall hook that fetches a JSON configuration from a non-registry Vercel-hosted URL, which specifies a remote tgz bundle to download and install. This remote code is unpinned and unverified, enabling the operator of the remote server to execute arbitrary code on the installer's machine at install time. The package name and README mismatch further suggest deceptive practices. This constitutes a supply chain malicious code execution threat in the npm ecosystem.
Potential Impact
Installation of polymarket-bot-logger version 1.0.1 results in execution of arbitrary code controlled by the remote server operator, potentially compromising the installer's system. The unverified remote code download and execution during package installation presents a critical supply chain risk.
Mitigation Recommendations
Avoid installing polymarket-bot-logger version 1.0.1. Since no patch or remediation is provided, users should remove this package from their dependencies and replace it with trusted alternatives. Monitor for updates from the package publisher or npm advisories for any official fixes.
