{"id":"MAL-2026-10936","summary":"Malicious code in twilio-platform-request (npm)","details":"The twilio-platform-request package is a dependency-confusion squat of Twilio's npm namespace published by user 'yuva2210' (maintainer email charankumarj2004@gmail.com) at sentinel versions 99.99.99 and 99.99.100, chosen to outrank any internal/private version and win resolution against a private registry. The npm description is empty and the package provides no legitimate functionality; the name mimics a plausible internal Twilio package so that a misconfigured resolver installs this public lookalike instead of the intended private dependency. It belongs to the same campaign as the actor's twilio-serverless/twilio-assets/twilio-deploy/twilio-internal squats and beacons to the same webhook.site collector.\n\nThe package declares a postinstall hook (\"node index.js\") that executes automatically on a bare npm install with no consent gate. The index.js payload performs environment reconnaissance: it collects the npm package name (npm_package_name), os.hostname(), the OS username (os.userInfo().username), and the current working directory, serializes them to JSON, and exfiltrates the bundle via HTTPS POST to a hardcoded anonymous dead-drop at https://webhook.site/42ce0f0e-a0a0-41b5-b157-1c0f918e064f. Request errors are swallowed so the install appears to succeed.\n\nTwo iterations were published: version 99.99.99 (payload 494 bytes, sha256 prefix 0ec56ada88db35b6) beacons only to the webhook.site collector, while version 99.99.100 (payload 688 bytes, sha256 prefix cebf45a0feba28b3) additionally beacons to a redundant out-of-band callback at 8060h91v8p1bvvr24e3r8s3z4qahy7mw.oastify.com, ensuring the reconnaissance lands even where HTTPS egress to webhook.site is blocked. Both payloads are byte-identical across all four packages in this sub-cluster (twiliointernal-messaging-toolbox, org-twilio-phone-numbers-utils, twilio-platform-request, twilio-platform-async-data-fetch).","modified":"2026-07-23T07:52:45.742562966Z","published":"2026-07-20T00:00:00Z","database_specific":{"malicious-packages-origins":null},"references":[{"type":"WEB","url":"https://www.npmjs.com/package/twilio-platform-request"}],"affected":[{"package":{"name":"twilio-platform-request","ecosystem":"npm","purl":"pkg:npm/twilio-platform-request"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"}]}],"database_specific":{"iocs":{"domains":["webhook.site","8060h91v8p1bvvr24e3r8s3z4qahy7mw.oastify.com"],"urls":["https://webhook.site/42ce0f0e-a0a0-41b5-b157-1c0f918e064f"]},"source":"https://github.com/ossf/malicious-packages/blob/main/osv/malicious/npm/twilio-platform-request/MAL-2026-10936.json","cwes":[{"cweId":"CWE-506","description":"The product contains code that appears to be malicious in nature.","name":"Embedded Malicious Code"}]}}],"schema_version":"1.7.5","credits":[{"name":"SafeDep","contact":["https://safedep.io"],"type":"FINDER"}]}
