I have experience reverse engineering malware samples using tools like IDA Pro and Ghidra. I analyze the code to understand its functionality, identify its communication patterns, and determine its purpose. This helps me develop signatures and countermeasures to protect against similar threats.

Question 3

What are your preferred tools for penetration testing?

Answer:
I use a variety of tools depending on the target and the scope of the test. Some of my favorites include Nmap for network scanning, Metasploit for exploitation, Burp Suite for web application testing, and Wireshark for packet analysis. I am also comfortable writing custom scripts in Python or Bash to automate tasks.

Question 4

How do you stay up-to-date with the latest security threats and vulnerabilities?

Answer:
I regularly read security blogs and news articles from reputable sources like KrebsOnSecurity, SANS Institute, and OWASP.
