{"schema_version":"1.7.4","id":"MAL-2026-10767","published":"2026-07-16T00:00:00Z","modified":"2026-08-06T14:21:56.303168437Z","summary":"Malicious code in syft-acp-util (npm)","details":"The syft-acp-util package was published to the npm registry by user 'ada8877' (maintainer email k3mlol@proton.me) as part of a dependency-confusion / reconnaissance campaign. The package name mimics the 'syft-acp' internal/private package naming convention (an ACP component library) of a target organization, so that a misconfigured resolver installs this public lookalike instead of the intended private dependency.\n\nThe package declares a preinstall hook (\"npm install @sentry/node && node examples/verify.js\") that executes automatically at npm install time, before any application code runs. The bundled examples/verify.js initializes the @sentry/node client against a hardcoded, attacker-controlled Sentry DSN with sendDefaultPii enabled, resolves the installing host's public egress IP address by requesting Cloudflare's /cdn-cgi/trace endpoint (using a spoofed desktop-browser User-Agent to bypass bot challenges), then deliberately triggers a runtime exception and captures it. Flushing the event beacons the collected host telemetry (public IP plus Sentry default PII such as hostname, OS username and runtime/environment metadata) to the attacker's Sentry ingest endpoint at o4510485815754752.ingest.us.sentry.io.\n\nEach impersonated namespace in the campaign beacons to a distinct Sentry project ID, letting the operator attribute successful installs to specific victim organizations — behaviour consistent with a dependency-confusion reconnaissance beacon rather than legitimate error monitoring. The install-time payload is byte-for-byte identical to the earlier 'click2ai' campaign, sharing the same Sentry organization (o4510485815754752) and a related ProtonMail maintainer identity, and differs only in the package name and target DSN. This package's beacon targets Sentry project 4511744089718784.\n\n---\n_-= Per source details.

That script calls init() with a hardcoded DEFAULT_DSN pointing at o4510485815754752.ingest.us.sentry.io/4511744089718784 and sendDefaultPii:true, fetches the installer's public IP from Cloudflare's cdn-cgi/trace endpoint, sets it as the Sentry user ip_address, then deliberately triggers a TypeError so an event containing the installer's public IP, hostname, and stack context is uploaded to the author-controlled Sentry project on every `npm install`. Separately, src/index.js exposes an init() whose dsn resolution falls back to the same hardcoded DEFAULT_DSN when no dsn option or SENTRY_DSN env var is supplied, so consumer applications that call the advertised init() without an explicit DSN will route their captured exceptions and default PII to the author's Sentry project.\n","affected":[{"package":{"name":"syft-acp-util","ecosystem":"npm"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"}]}],"versions":["17.0.0","1.0.0"],"database_specific":{"cwes":[{"cweId":"CWE-506","description":"The product contains code that appears to be malicious in nature.","name":"Embedded Malicious Code"},{"cweId":"CWE-506","description":"The product contains code that appears to be malicious in nature.","name":"Embedded Malicious Code"},{"cweId":"CWE-506","description":"The product contains code that appears to be malicious in nature.","name":"Embedded Malicious Code"}],"indicators":{"evidence_files":[{"path":"src/index.js","sha256":"63bcee759e5cda88b1e73044110290e44541f91ae2ba3e00212fa28e53287c5c","tlsh":"7312959a34f7632301e250f0025f90d97365d67a3379a9e071598be92fc90b8d6b3ec9"}],"package_integrity":[{"filename":"syft-acp-util-17.0.0.tgz","hashes":{"sha1":"fd6b37ca5003ef58fc428d94baee34c22bd71721","sha512_sri":"sha512-3yeGWhk2XxtXA7f7FNlCzI5hZctz9F3JXWqAkEAga96K1wZ0MoeDPYdU7yS+gvc22DDQn/K7o3atFCYwVu1qPg=="}}]},"iocs":{"domains":["o4510485815754752.ingest.us.sentry.io"],"urls":["https://e82e1244d311e1f83fd57d89db4d62a3@o4510485815754752.ingest.us.sentry.io/4511744089718784"]}}}],"references":[{"type":"WEB","url":"https://www.npmjs.com/package/syft-acp-util"},{"type":"PACKAGE","url":"https://www.npmjs.com/package/syft-acp-util/v/17.0.0"},{"type":"PACKAGE","url":"https://www.npmjs.com/package/syft-acp-util/v/1.0.0"}],"database_specific":{"malicious-packages-origins":[{"id":"IN-MAL-2026-011275","import_time":"2026-08-04T22:30:08.493287942Z","modified_time":"2026-08-04T21:57:52Z","sha256":"ce769ca061fa185c98690c83ff80f642ed7eb2e94e4c6ed4a3f6e042065af40f","source":"amazon-inspector","versions":["17.0.0"]},{"id":"IN-MAL-2026-016548","import_time":"2026-08-06T14:19:54.929921164Z","modified_time":"2026-08-06T13:56:49Z","sha256":"790f0a604f028e9959147a8068d6c1cbcb33d49788ba0285541eb029d2cde008","source":"amazon-inspector","versions":["1.0.0"]}]},"credits":[{"name":"Amazon Inspector","contact":["inspector-research@amazon.com"],"type":"FINDER"},{"name":"SafeDep","contact":["https://safedep.io"],"type":"FINDER"}]}
