PCCSE practice question 4 of 35

A customer is reviewing Container audits, and an audit has identified a cryptominer attack. Which three options could have generated this audit? (Choose three.)

Full set: 259 questions
Answer options
A: The value of the mined currency exceeds $100.
B: High CPU usage over time for the container is detected. Correct answer
C: Common cryptominer process name was found. Correct answer
D: The mined currency is associated with a user token.
E: Common cryptominer port usage was found. Correct answer
Correct Answer:
B. High CPU usage over time for the container is detected.; C. Common cryptominer process name was found.; E. Common cryptominer port usage was found.
Explanation

Prisma Cloud Compute identifies cryptomining attacks by detecting anomalous behavior and matching known threat signatures. Key indicators include: a container exhibiting unusually high and sustained CPU usage over time; the presence of processes with names common to cryptomining software (e.g., xmrig); and network connections to known mining pools, which often use specific, non-standard ports. These three technical indicators are actively monitored by the runtime defense mechanisms to generate a cryptominer audit.

Why Incorrect

A. Prisma Cloud has no mechanism to determine the monetary value of mined currency; its detection is based on system and network behavior.
D. Associating mined currency with a specific user token is not a function of runtime container security and is not a detectable event within the container.
