  "details": "Malicious npm package published by the `microsop` threat actor as part of a dependency-confusion campaign that impersonates internal tooling at Microsoft, Google Cloud, and PayPal using inflated semver values (e.g. 99.9.x, 100.1.x) to win npm resolution against private internal packages. All packages in the campaign falsely advertise themselves as \"Security Research PoC\" and execute on `preinstall` via `node index.js`, exfiltrating to disposable `webhook.site` endpoints.\n\nThis package targets PayPal-flavored internal naming and performs internal-registry / build-environment discovery. On install it reads `/root/.npmrc` (token values are partially scrubbed before exfil but the registry URL is kept, revealing the victim\u0027s private registry), enumerates neighbor packages under `/app/node_modules` and `/node_modules`, and runs `npm search paypal --json --limit=20` against whatever registry is configured to enumerate other PayPal-named packages worth targeting. The collected output is POSTed to `https://webhook.site/db976f48-5e71-4746-a905-1af291c19c1f` tagged `event: LINUX_INTERNAL_DISCOVERY`. Source contains Indonesian-language operator comments matching the rest of the campaign.",
