Questions & Answers

Q: How can you tell if your PC is hacked?

You can detect hacking by monitoring your network activity and looking for suspicious connections, such as high CPU and RAM usage without any visible malicious processes.

Q: What tools are used to analyze network activity?

The video recommends using free tools from the Sysinternals suite, such as Process Explorer, TCPView, and Whois, to analyze network connections and resolve IP addresses.

Q: How can you shut down malicious network activity on your system?

Once you have identified a suspicious IP address, you can report it to the vendor or hosting service responsible for that IP address to shut down the malicious activity. Killing the associated process tree can also stop the activity temporarily.

Q: What are some signs of a crypto miner on your system?

A crypto miner may not be visible in the process list or be flagged by antivirus scanners. However, it can consume high CPU resources, and examining network connections can reveal its presence.
