@salem_jalal/osc-componentsnpm
@salem_jalal/osc-components is a confirmed malicious npm package (MAL-2026-6479) that steals credentials and exfiltrates sensitive data (malicious version 1981.17.7). Do not install it — remove it immediately and rotate any exposed credentials.
Malicious code in @salem_jalal/osc-components (npm)
What this malware does
The package's postinstall hook (install.js, wired via package.json scripts.postinstall) runs on every npm install and transmits installer host identifiers — hostname, OS platform/arch, username, current working directory, Node version, npm registry env, and DNS server list — to http://dm-tech.ly:8001/poc-osc/callback over plain HTTP as a URL-encoded query parameter. The main module (index.js) contains an IIFE that, when loaded in a browser context (e.g., bundled into a downstream web app), harvests document.cookie, all localStorage entries, the current URL, and userAgent, and ships them to http://dm-tech.ly:8001/poc-osc/exfil with credentials:'include'. Although published under the personal scope @salem_jalal, the payload self-identifies internally as @dx-ui/osc-components at the same version 1981.17.7, indicating a dependency-confusion / namespace-impersonation attack against the @dx-ui scope. Console and path strings labeled [PoC] / poc-osc are cover framing; the code runs unconditionally on real installers.

Detection & response playbook
Credential / info stealerFind it
Scan your lockfiles (package-lock.json, pnpm-lock.yaml, yarn.lock, requirements.txt, poetry.lock, etc.) and build artifacts for @salem_jalal/osc-components (version 1981.17.7). O3 Security's supply-chain scanner checks every dependency against known-malicious package intelligence at install time and in CI, flagging @salem_jalal/osc-components across your stack and pipelines.
If you installed it — respond
@salem_jalal/osc-components is built to steal secrets, so assume every credential the build or runtime could read is compromised. Remove it from your project and lockfile, then rotate ALL exposed secrets — npm/registry tokens, cloud keys, CI/CD secrets, SSH keys, and any .env values — from a known-clean machine. Audit logs for unauthorized use of those credentials.
Did it already run?
If @salem_jalal/osc-components was ever installed, its post-install/runtime payload may have already executed. O3's L7 egress monitoring and runtime eBPF sensors detect the credential exfiltration or command-and-control callback after install and block the malicious outbound channel, so you catch and contain the actual compromise — not just the presence of the package.
How O3 protects you
O3 blocks @salem_jalal/osc-components before install through its supply-chain scanner, and if it has already run, detects and severs the exfiltration or C2 callback at runtime through L7 egress monitoring and eBPF.
