Could a cloud account be compromised without the password being stolen?¶
Yes. An attacker may misuse an existing session, deceive a user into granting application consent, control a recovery route, obtain a token or API key, or abuse delegated or administrative authority. The password can remain unchanged and unknown throughout.
The missing password event helps classify the route¶
Dave's password works normally and there is no new password sign-in beside a suspicious file download. That does not disprove compromise. It shifts attention to the authority the service actually accepted.
Prove the route rather than listing possibilities¶
Start with the suspicious resource event and preserve its actor, application, session/request, object, time and result. Follow those identifiers to the session creation, consent, recovery change, delegation, role assignment or workload credential. Then compare the device, application and communication evidence.
Access without password knowledge explains the wider technical possibilities. This card adds the compromise proposition: the route must have been obtained or used without authority. Recognising unauthorised access shows how independent indicators support that conclusion.
Changing the password alone may leave other routes active. Protective action may require session, token, application, recovery, delegation or workload revocation, but intervention changes evidence. Record the pre-change state and each action where circumstances allow.
The point to remember
A password can remain secret while another credential or permission is compromised. Identify and evidence the accepted route, then test whether its acquisition or use lacked authority.
