Hello again! :ablobcatpoprev:
Today I reviewed tools like TCPdump and Nmap, both part of the Cybersecurity 101 networking module. I'm already comfortable analyzing packets with Wireshark, but combining it with the command-line tool TCPdump allows me not only to capture live traffic but also to read and analyze .pcap files directly from the terminal.
Starting tomorrow, I'll move into cryptography theory and begin working with tools like John the Ripper and Hashcat for password cracking practice.
For CS50, I completed the main lecture today. Tomorrow I'll finish the remaining lecture segments and then jump straight into the problem sets.
Hello again! :ablobcatnodfast:
Today, I reviewed the linux Terminal commands, command prompt commands, and lastly Powershell. It was extremely useful to understand the Powershell, because I have had less exposure to it than terminal and cmd.
After reviewing the CLI material, I moved to networking concepts with practical use cases. It can be a great boost for my learning.
Lastly, I have worked on DNA problem set in the Python section of the CS50 course, and I'm working with csv files, and trying to make a program that does DNA profiling.
Hello again! :ablobcatnodfast:
Usually, Sundays are more productive because I get extra practice in, but today I ran into an issue.
I started with some challenges from DiceCTF. Specifically, I did the misc challenge with the PCAP file, and then my PC froze.
I checked the event viewer and the disk for corruption, but there were no issues. I also ran the Windows Memory Diagnostic Tool, but it didn't help much.
My last option is to run MemTest86. I plan to run the tests soon. There is a high probability that the issue is caused by faulty or unstable RAM.
