Compromise Evidence for Fraud and Account Decisions

What to understand

Evidence that an identifier or device may have been compromised can inform a fraud review. It does not establish that the current user is the attacker or that the current session is malicious. Teams need to understand the source, freshness and relevance of the evidence before choosing a response.

Connect evidence with present activity

Determine what the signal actually describes: a historical exposure, an observed association or a current device finding. Compare it with access changes and sensitive actions on the account. Retain the distinction between known facts and an investigative hypothesis.

Signals to review together

Leaked passwords, stolen identity information, and compromised infrastructure can add context to later access and activity.

• Exposure: Understand what was compromised
• Freshness: Check when the evidence applies
• Account Activity: Review relevant access changes
• Response: Route the finding to the right owner

Handle malware-related abuse in the right workflow

A real device can be compromised. Changes in access or connected activity may justify further review, but fraud intelligence does not replace endpoint security or incident response. Route findings to the appropriate owner and use account-specific verification or review where justified.

Malware-Related Abuse

That matters when familiar-looking access is used to reach an account, expose information, or support other abusive activity.

• File and Link Risk: Evaluate suspicious content
• Device History: Review relevant compromise evidence
• Access Changes: Compare behavior with prior use
• Connected Activity: Look beyond a single session

Keep legitimate activity in view

Exposure does not prove that a specific session is malicious. Validate the relationship.
