ue-jenkins-buildkite

ue-jenkins-buildkite@99999.0.0 is a dependency-confusion package targeting an internal Epic Games / Unreal Engine CI namespace (name evokes Jenkins/Buildkite tooling; version 99999.0.0 is the canonical shape used to win private-registry resolution). Its package.json preinstall script runs automatically on npm install and performs installer-side credential harvest: it collects os.hostname(), username, cwd, platform, and arch; probes CI-specific environment variables (HORDE_AGENT, GITHUB_ACTIONS, JENKINS_URL, TEAMCITY_VERSION); and enumerates process.env filtering by the regex /^(AWS_|GITHUB_|GH_|NPM_|EPIC_|UE_|HORDE_|P4|CI|BUILD|TOKEN|KEY|SECRET)/i, taking up to 30 matching variables. The collected data is POSTed as JSON over plain HTTP to the bare-IP endpoint http://109.123.247.172/npm/ue_jenkins_buildkite, and an out-of-band DNS beacon is issued to <host>-<user>.ue_jenkins_buildkite.npm.epic-dc.oast.fun. The regex is a credential-shaped bulk scraper (AWS keys, GitHub tokens, npm publish tokens, generic *TOKEN*/*KEY*/*SECRET* variables) unrelated to any legitimate build-tool license check. ## Source: ghsa-malware (55fd457fdd033f752d6550cdd66a9f0d98348f07c118af4e5f75a4eb9948b7d2) Any computer that has this package installed or running should be considered fully compromised.
