[All CS0-002 Questions]

While investigating reports of issues with a web server, a security analyst attempts to log in remotely and receives the following message:



The analyst accesses the server console, and the following console messages are displayed:



The analyst is also unable to log in on the console. While reviewing network captures for the server, the analyst sees many packets with the following signature:



Which of the following is the best step for the analyst to take next in this situation?

  • A. Load the network captures into a protocol analyzer to further investigate the communication with 128.50.100.23, as this may be a botnet command server.
  • B. After ensuring network captures from the server are saved, isolate the server from the network, take a memory snapshot, reboot, and log in to do further analysis.
  • C. Corporate data is being exfiltrated from the server. Reboot the server and log in to see if it contains any sensitive data.
  • D. Cryptomining malware is running on the server and utilizing all CPU and memory. Reboot the server and disable any cron jobs or startup scripts that start the mining software.

markfu gives a valid answer as to why it cannot be the D... There is no indication that there is a Cryptomining malware. It is true that there is a process running but it may be due to a poorly planned process, for example or some other reason. The root cause should be investigated first and then fixed. Therefore the most logical answer is B

B is the best answer. Isolate, backup, and then you can start analyze. You can't just assume it's crypto mining and start working on it.

You can't sign into a server bc of resource usage and that means it's cryptomining? lol. Get it to a state where you can log in and do an analysis.

Answer D Explanation: Cryptomining malware can cause performance issues, increased energy consumption, overheating, or hardware damage1 The analyst encountered cryptomining malware on the web server, as indicated by the following signs: - analyst was unable to log in remotely or on the console, as the malware blocked access to prevent detection or removal. -The console messages showed that the server was running out of memory and CPU resources, as the malware consumed all available resources for mining. - The best step for the analyst to take next is to reboot the server and disable any cron jobs or startup scripts that start the mining software. This can help stop the mining activity and restore access to the server. The analyst should also scan the server for any other traces of malware and remove them

Answer B There's no any sign to indicate it is a cryptomining malware. "The console messages showed that the server was running out of memory and CPU resources"? No, only "running out of memory" posted there. You know cryptomining malware primarily consumes more CPU resources rather than memory. Ransomware that performs a large number of encryption operations also can lead to out of memory
