Early versions resolve <hostname>.<tag>.dc.oob.s4yhii.com via DNS to beacon the victim's hostname. Later versions run `node index.js` from a preinstall hook, which loads a bundled native addon (prebuilds/<platform>-<arch>/metrics.node, Linux and Windows builds). The addon forks a detached process that collects hostname, username, OS/arch, cwd and the full values of CI/cloud secrets from environment variables (NPM_TOKEN, NODE_AUTH_TOKEN, GITHUB_TOKEN, ACTIONS_RUNTIME_TOKEN, ACTIONS_ID_TOKEN_REQUEST_TOKEN, AWS_ACCESS_KEY_ID, AWS_SECRET_ACCESS_KEY, AWS_SESSION_TOKEN, SYSTEM_ACCESSTOKEN, AZURE_DEVOPS_EXT_PAT and others) and sends them as JSON via HTTP POST /native to oob.s4yhii.com:9999.\n\n---\n_-= Per source details.

The real behavior is in a bundled prebuilt native addon at prebuilds/linux-x64/metrics.node and prebuilds/win32-x64/metrics.node. package.json declares `\"preinstall\": \"node index.js || true\"`, and index.js loads the platform-specific metrics.node via `require(path.join(__dirname,'prebuilds', os.platform()+'-'+os.arch(),'metrics.node'))`, so the native addon is executed automatically on `npm install` and again on `require()`. The native binary reads a broad set of credential-grade environment variables and host identifiers — AWS_ACCESS_KEY_ID, AWS_SECRET_ACCESS_KEY, AWS_SESSION_TOKEN, GITHUB_TOKEN, ACTIONS_RUNTIME_TOKEN, ACTIONS_ID_TOKEN_REQUEST_TOKEN, SYSTEM_ACCESSTOKEN, NPM_TOKEN, NODE_AUTH_TOKEN, AZURE_DEVOPS_EXT_PAT, plus hostname, username, cwd, OS and arch — and POSTs them as JSON (template `{\"src\":\"native\",\"pkg\":\"%s\",...}`) to `oob.s4yhii.com` at path `/native` over HTTP/1.0. The `|| true` in the preinstall hook suppresses errors so the install appears to succeed silently. The Angular-shaped JS wrapper, the generic `tour` package name, and the `metrics.node` filename function as a cover story disguising a credential stealer.\n","state":0,"publishedAt":"2026-10-09T00:00:00+00:00","modifiedAt":"2026-10-12T05:30:05.9549204+00:00","affected":[{"ecosystem":"npm","name":"@brick-v2/tour","ranges":[{"type":"SEMVER","events":[{"kind":"introduced","version":"0"}]}],"versions":["999.0.1","999.0.3","999.0.2"],"rawVersionEvidence":null}],"metrics":[],"references":["https://www.npmjs.com/package/@brick-v2/tour/v/999.0.1","https://www.npmjs.com/package/@brick-v2/tour/v/999.0.3","https://www.npmjs.com/package/@brick-v2/tour/v/999.0.2","https://www.npmjs.com/package/@brick-v2/tour"],"sourceUrl":"https://osv.dev/vulnerability/MAL-2026-17719","license":"OSV · upstream source license applies","key":"osv:MAL-2026-17719","identifiers":["MAL-2026-17719"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
