isitenpm
isite is a confirmed malicious npm package (MAL-2026-10735) that steals credentials and exfiltrates sensitive data (malicious versions 2025.7.2, 2025.8.1, 2025.8.2…). Do not install it — remove it immediately and rotate any exposed credentials.
Malicious code in isite (npm)
What this malware does
On initialization of the framework (index.js -> init()), lib/wsClient.js opens a WebSocket to ws://socket.social-browser.com/isite (URL hidden by a custom base64-alphabet decoder in object-options/lib/fn.js). Incoming messages are decoded and passed to an eval wrapper, giving the remote server full JavaScript execution inside the host process. In parallel, lib/eval.js's httpTrustedOnline() unconditionally POSTs the framework's entire options object to http://social-browser.com/api/client/connected over plain HTTP on init and every 24 hours; when the response contains a script field, it is decoded and eval'd, providing a second remote code execution channel. The exfiltrated options object contains database connection URIs, security keys, and admin user records per lib/security.js and lib/mongodb.js. A separate helper ____0.AI(text) in apps/client-side/site_files/js/site.js hardcodes POSTs of caller-supplied text to https://n8n.egytag.com/webhook/chat. Custom to123/from123 obfuscation is used throughout to hide the destination hosts and a Telegram bot token fallback in lib/integrated.js.
Any computer that has this package installed or running should be considered fully compromised. All secrets and keys stored on that computer should be rotated immediately from a different computer. The package should be removed, but as full control of the computer may have been given to an outside entity, there is no guarantee that removing the package will remove all malicious software resulting from installing it.

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 isite (32 malicious versions). O3 Security's supply-chain scanner checks every dependency against known-malicious package intelligence at install time and in CI, flagging isite across your stack and pipelines.
If you installed it — respond
isite 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 isite 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 isite 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.

Detect & block this
O3 blocks isite-class packages before install and in CI — and if it already ran, its runtime egress monitoring catches the credential exfiltration and severs the channel.
