OpenSSF/OSV malware advisory MAL-2026-5833 identifies this version as malicious and supplies the Firewall block.

OpenSSF/OSV advisory MAL-2026-5833 confirms this npm version as malicious. On \`npm install\`, the package's \`scripts.postinstall\` runs \`src/\_postinstall.js\`, which spawns a detached Node child that collects the installer's hostname, username, platform/arch, cwd, Node version, npm registry, all non-internal IPv4 addresses, and the keys of environment variables matching /NPM|NODE|CI|JENKINS|GIT|BUILD|RUNNER|DOCKER|KUBE|REGISTRY/...

## Public findings

### 1. High: Osv Malicious Advisory
- **Category:** External Intel
- **Confidence:** 100.0%

On \`npm install\`, the package's \`scripts.postinstall\` runs \`src/\_postinstall.js\`, which spawns a detached Node child that collects the installer's hostname, username, platform/arch, cwd, Node version, npm registry, all non-internal IPv4 addresses, and the keys of environment variables matching /NPM|NODE|CI|JENKINS|GIT|BUILD|RUNNER|DOCKER|KUBE|REGISTRY/. The collected data is HTTPS-POSTed to a hardcoded DingTalk bot webhook (\`https://oapi.dingtalk.com/robot/send?access\_token=4e5cb67f...df393\`). Before sending, the script checks the username and hostname against an analyst/sandbox keyword list (\`sandbox\`, \`malware\`, \`analyst\`, \`cuckoo\`, \`analysis\`, \`sample\`) and silently no-ops if any match — explicit anti-analysis evasion. The combination of automatic install-time execution, host/network reconnaissance scoped to CI/build runners, hardcoded attacker-controlled callback, and sandbox-evasion gating is the canonical dependency-confusion beacon shape. Installing this package leaks internal hostnames, IP topology, and CI/build environment fingerprints to the operator of the DingTalk webhook, enabling targeted follow-on attacks against the installer's internal infrastructure.
