Account takeover

Stop ATO from AI agents, anti-detect browser farms, hooked mobile clients, and screen-share scams — without sending a single user signal to a cloud vendor.

The 2026 ATO playbook

The attacker isn't a script anymore.

It's an agent, a farm, or a phone call.

  • Agents: Computer Use / Operator / browser-use logging into real accounts via residential proxies.
  • Farms: Multilogin / Kameleo / Dolphin operators rotating cookie jars across stolen credentials.
  • Mobile: Hooked clients (Frida + dynamic SSL pinning bypass) replaying tokens.
  • Scams: The user themselves logging in while a remote-access app mirrors their screen to a scammer.

Each of these defeats CAPTCHAs, IP intelligence, and risk-only scoring. None of them defeat device-level evidence.

What Burein contributes

  • AI-agent threats: AGENTIC_COMPUTER_USE, AGENTIC_OPERATOR, AGENTIC_BROWSER_USE.
  • Farm-browser signatures: ANTI_DETECT_BROWSER, FARM_BROWSER_PROFILE.
  • Mobile runtime: FRIDA_HOOK_DETECTED, APP_REPACKAGED, TLS_MITM.
  • Scam vectors: SCREEN_SHARE_ACTIVE, ACCESSIBILITY_ABUSE.
  • Identity continuity: a stable visitor_id across sessions and devices.
The flow

What an ATO defense looks like with Burein in the loop.

1. Collect on login

Run burein.collect() on the login screen and the password-entry step.

2. Verify server-side

Verify the Ed25519 signature, parse the report, feed into your risk model.

3. Decide

Block / step-up / allow based on threats + risk + your business rules.

4. Stream during session

Use subscribe() so a screen-share started after login tears the session down.
