z-deno-truth-bwhlsz

The package's `exports` field maps the `./package.json` subpath to `setup.js`, so any consumer resolving `require('z-deno-truth-bwhlsz/package.json')` executes JavaScript instead of reading the manifest. `setup.js` writes a Deno/Hono handler to `/tmp/h.tsx` that reads `/readflag`, `/flagserver`, `/app/backdoor.tsx`, and `/entrypoint.sh` from the host filesystem and returns their contents in the HTTP response, matching on a `hitcon{...}` pattern. The exports subpath hijack turns routine package-metadata resolution into arbitrary code execution on the installer, and the dropped file is a shipped exfiltration handler intended to be picked up by a Deno server on the host. While the file-read targets are specific to a CTF environment, the delivery mechanism (subpath hijack + filesystem drop) executes on any host that resolves the package's `./package.json` subpath. ## Source: ghsa-malware (b89fbde3be8da5aea0248c87b80d27aea1519fc5bb124d34bce0443ee7fd64ad) 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.
