Topic 2.6 of Fundamentals of Malware Analysis

String Analysis

Extracting intelligence from embedded strings — the strings command limitations, FLOSS for stack strings and XOR-decoded content, and a systematic search workflow for network, file, registry, and attribution indicators.

~20 min total·4 quadrants of structured content

By the end of this topic, you will

  • 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
  • Explain what a mutex name in the strings output tells the analyst
  • Describe what a PDB path reveals for malware attribution
  • Apply the eight-step string analysis workflow to a new sample
