## What is MAL-2026-15692?

MAL-2026-15692 is a malicious package in unifi-credential-server, published on 24 Aug 2026. 

### Official description

package.json declares a preinstall hook that runs index.js on npm install. index.js collects hostname, username, working directory, internal IPv4 addresses from os.networkInterfaces(), and CI/build environment variables (GITHUB_REPOSITORY, GITHUB_RUN_ID, GITLAB_CI, npm_config_registry, npm_package_name, AWS_REGION, JENKINS_URL, and others), hex-encodes the payload into <=60-character DNS labels appended to the hardcoded base domain d8hjn6ap4rntta9vj5ve0jkl1seb4k3kci.oast.me, and exfiltrates via dns.resolve() of the constructed FQDN plus an https.get() to the same host. A secondary DNS query using the package name as a subdomain is also emitted. The name unifi-credential-server and version 99.0.0 are consistent with a dependency-confusion lure targeting internal builds that resolve the name against the public registry.

## What should I do about MAL-2026-15692?

Remove the package from your dependencies and lockfiles, then rotate any secrets on machines where it was installed.
