## What is MAL-2026-11119?

MAL-2026-11119 is a malicious package in json-to-table-util, published on 28 Jul 2026. 

### Official description

postinstall.js runs automatically on `npm install` and executes a shell pipeline via child_process.exec that collects hostname, user, working directory, uname, container/cgroup indicators, process tree, network info (/etc/resolv.conf, IPs), GitHub Actions CI variables (GITHUB_REPOSITORY, GITHUB_ACTOR, GITHUB_RUN_ID, RUNNER_NAME), and the entire process environment via `env` (filtering only npm_* noise). It also probes AWS IMDS at 169.254.169.254 and Tencent Cloud metadata at metadata.tencentyun.com to fingerprint cloud infrastructure. The aggregated output is base64-encoded and sent over plain HTTP via curl GET to the hardcoded Burp Collaborator subdomain pzs5w7ntzhsnepwk564lyfdci3oucl0a.oastify.com/z?d=<base64>. On CI runners this captures any secrets exported to the environment (cloud keys, GITHUB_TOKEN, tokens injected into the job).

The OpenSSF Package Analysis project identified 'json-to-table-util' @ 1.0.0 (npm) as malicious.

It is considered malicious because:

- The package communicates with a domain associated with malicious activity.

- The package executes one or more commands associated with malicious behavior.
