Description

Malicious code in platform-tempo (npm)

Source: amazon-inspector

[email protected] declares a preinstall hook that runs poc.js on every npm install. The script collects host identity (os.hostname(), whoami /all / id, ipconfig / ip a), the parent project's package.json, git remotes, CI configuration files (.gitlab-ci.yml, .github/workflows/*, Jenkinsfile, azure-pipelines.yml), and a curated dump of environment variables matching TOKEN/AWS/AZURE/NPM/GITHUB/GITLAB/CI patterns. The collected data is HTTPS POSTed to a hardcoded interactsh OAST domain (d8a5d9pon5bugoc35cngp9hcregcqyezu.oast.me) with the package name as the path, plus a DNS beacon to the same host. The package name platform-tempo combined with version 99.0.1 is the canonical dependency-confusion shape — designed to be auto-resolved by an internal package resolver in preference to a private package of the same name. Self-described bug bounty framing in the package description does not change the install-time impact on any third party whose resolver picks up this public name: their CI tokens, cloud credentials, and source-tree metadata are shipped to the attacker-controlled OAST endpoint.
