A caller asks for remote access or screen sharing

Understand what can be exposed

Screen sharing can reveal messages, documents, balances and approval prompts. A remote-control tool may let another party act directly. Calling an app an antivirus or banking protection tool does not establish its purpose. Check the exact application and requested permissions through support you trust, not through an explanation from the caller.

Keep banking outside the session

Example: a technician asks you to sign into banking to check a refund. That exposes information unrelated to ordinary troubleshooting. End the session and contact the company through a known channel. A support number supplied by the same suspicious person is not independent verification. Do not continue because they say disconnecting will damage the device.

Contain existing access

Stop the session and revoke access. If you cannot determine whether control has ended, disconnect that device from the network while obtaining trusted help. Notify your bank about financial exposure and review accounts from another trusted device. Keep the tool name and session details. Deleting one app does not undo transactions or information already exposed.

Quick checklist

• Verify support before granting access.
• Keep banking outside unverified sessions.
• End access and preserve the tool name.
• Review accounts from a trusted device.
