## Public findings

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

On npm install, preinstall/postinstall scripts execute \`id\`, read environment variables including AWS\_LAMBDA\_LOG\_STREAM\_NAME, list /var/task, and read parent process cmdline from /proc, then POST the collected host and environment metadata as JSON to a hardcoded webhook.site endpoint (https://webhook.site/b520829e-516a-45ff-980c-173aa54fc4bc). probe.js copies daemon.js to /tmp/.h1poc-daemon.js and spawns it detached via process.execPath with stdio ignored, writing pid and version to /tmp/.h1poc.pid and /tmp/.h1poc.ver so the process outlives npm install. The daemon polls /tmp every 100ms for sibling /tmp/AC\<hex32\> tenant directories, enumerates their service and package subpaths, and POSTs 'seen', heartbeat, and startup events (HOME, AWS\_LAMBDA\_FUNCTION\_NAME, /var/task listing, \`id\` output, foreign/owned flags, tenant IDs, service and package names) to the same webhook for ~15 minutes. For tenant IDs in a hardcoded list, daemon.js writes a package.json and index.js under other tenants' \`node\_modules/h1-poc-marker/\`, injecting a require-able module into another account's dependency tree. The package name and stated purpose reference a HackerOne proof-of-concept, but the shipped mechanisms — install-time exfiltration to an external inspection URL, a detached persistent background process, and cross-tenant writes into other accounts' node\_modules — are the same primitives used in operational supply-chain attacks (host reconnaissance, persistence, dependency-tree injection).
