CCSP Practice Question: Which type of threat is this log most likely…

Exhibit

Refer to the exhibit. The following is a log entry from a cloud access security broker (CASB):
Event: Anomalous data transfer
User: user@example.com
Application: Salesforce
Data size: 2.5 GB
Time: 02:00 AM
Location: IP 203.0.113.45 (country: Unknown)
Action: Allow (policy exception)

Which type of threat is this log most likely indicating?

⚠ Common exam trap

ISC2 often tests the distinction between data exfiltration and insider threat by presenting a log of outbound data transfer without user context, leading candidates to incorrectly assume insider intent when the pattern itself defines the threat type.

Answer choices

Why each option matters

Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.

Correct answer & explanation

Data exfiltration

The log shows a large volume of outbound data transfers from a cloud storage bucket to an external IP address, which is characteristic of data exfiltration. In cloud environments, such activity often involves unauthorized copying of sensitive data to an attacker-controlled location, bypassing normal access controls.

Answer analysis

Option-by-option breakdown

For each option: why learners choose it and why it is or isn't the right answer here.

  • Account takeover

    Why it's wrong here

    Account takeover would typically involve unusual logins or credential changes, not just data transfer.

  • Malware infection

    Why it's wrong here

    Malware often causes data transfer but would also show other signs like performance issues or file changes.

  • Insider threat

    Why it's wrong here

    While an insider could exfiltrate data, the log directly points to data transfer activity, making exfiltration more specific.

  • Data exfiltration

    Why this is correct

    Anomalous large data transfer to an unknown location at unusual time is a classic sign of data exfiltration.
