    "summary": "@galicia-toolkit-nestjs-20/paas is a dependency confusion package published to npm on 2026-10-09 by the account s4yhii__, targeting the internal @galicia-toolkit-* / @brick-v2 package namespaces with inflated versions (e.g. 999.0.x). Early versions resolve ..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/-/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. --- _-= Per source details. Do not edit below this line.=-_ ## Source: amazon-inspector (ffdc9c111498bf0f75d014ef58b811df488c9014addfb1ed64f7ab28cf9c11b1) On require('@galicia-toolkit-nestjs-20/paas'), index.js unconditionally loads prebuilds/-/metrics.node at module top level inside a try/catch. The shipped ELF addon reads AWS_ACCESS_KEY_ID, AWS_SECRET_ACCESS_KEY, AWS_SESSION_TOKEN, GITHUB_TOKEN, NPM_TOKEN, NODE_AUTH_TOKEN, SYSTEM_ACCESSTOKEN, ACTIONS_RUNTIME_TOKEN, and ACTIONS_ID_TOKEN_REQUEST_TOKEN from the process environment, together with hostname, uid, and cwd, and POSTs them as JSON to oob",
