Topic 4.5 of Malicious Web & Document Files

Malicious RTF Analysis

RTF file structure, five reasons attackers prefer RTF, CVE-2017-11882 and CVE-2017-0199 exploitation chains, rtfobj extraction, scdbg shellcode emulation, and high-risk indicator recognition.

~25 min total·4 quadrants of structured content

By the end of this topic, you will

  • Explain five properties of RTF that make it attractive to attackers
  • Describe the CVE-2017-11882 exploitation chain from document open to shellcode execution
  • Distinguish CVE-2017-0199 from CVE-2017-11882 based on mechanism and class name
  • Run rtfobj and identify a CVE-2017-11882 sample from the class name in output
  • Use scdbg to emulate extracted shellcode and extract download URL and drop path as IOCs
  • Apply the four-step RTF triage workflow to an unknown sample
