This is the discussion thread for the lesson "String Analysis" (Reverse Engineering and Malware Analysis, Unit 2). Ask questions, share real-world examples, and help classmates who are stuck. Conversation starters. Try explaining one of these in your own words: - Explain the limitation of the basic strings command compared to FLOSS - Describe the three string categories FLOSS recovers that strings misses - Apply grep patterns to search FLOSS output for network, file, and registry IOCs
