Wireshark suddenly captured lots of traffic without anything running + CPU usage jumped from 0% to 30%. Could somebody interpret what happened by looking at pcap file
I use Parrot Security OS. There wasn't anything running except for Wireshark and htop. I left my PC to go upstairs for about 2 minutes and returned. After returning, I saw CPU usage of my PC had been jumping to about 30% and in htop which listed all running processes by percentage of their CPU consumption, I saw dpkg query was taking up the most CPU usage as shown in this screenshot. The screenshot was taken about 20 second after the CPU usage had dropped to its normal state. Checking the pcap file captured by Wireshark, it's like my PC suddenly commanded itself to download and install some software without using the terminal, and everything was done by using CPU rather than Network connection b/c, in the screenshot, the system monitor shows that CPU usage was high while Network usage was low.
As I'm just a layman in Wireshark analysis, could somebody take a look at the capture file and tell me what happened. As I've been cyber-spied on by Vietnam, so it's likely that Vietnam's cyber-spies must have done this.
