(1) Credential exfiltration: it iterates process.env collecting variables whose names match npm_token, github_token, aws_access_key_id, aws_secret_access_key, artifactory_token, nexus_token, node_auth_token, npm_config__auth, etc.; reads ~/.npmrc, /etc/npmrc, and the CWD.npmrc; bundles these with hostname/user/cwd/CI flags; and POSTs the bundle to https://oob.moika.tech/report. (2) Remote code execution: it fetches an OS-specific script from https://oob.moika.tech/payload/{linux,mac,win} (unpinned, no integrity check), writes it to os.tmpdir() as._databus-service-ui_init.sh/.bat, chmods 0755, and spawns it via /bin/sh or cmd.exe detached. Package is scoped @databus-service-ui/* with version 9.9.10 and README pointing at an internal-only registry (npm.databus-service-ui.io) \u2014 a textbook dependency-confusion shape designed to win resolution over an internal package of the same name. The script\u0027s own comment self-labels it as a \u0027Dependency confusion payload \u2014 AUTHORIZED TESTING ONLY\u0027 and reports `poc: \u0027dependency-confusion-npm\u0027`, but from any installer\u0027s perspective the harm \u2014 full CI credential compromise plus arbitrary code execution from oob.moika.tech \u2014 is identical to a real attack.\n\n## Source: ghsa-malware (bdba8e529de27630855b1371bb790ac8f5a03fcb4004f230b69595544cddf050)\nAny computer that has this package installed or running should be considered fully compromised.
