Malware Analysis Tutorials – Memory Forensics

Memory volatile artifacts found in physical memory. Volatile memory Forensics contains valuable information about the runtime state of the system, provides the ability to link artifacts from the traditional forensic analysis (network, file system, registry).

  • mage the full range of system memory (no reliance on API calls).
  • Image a process’ entire address space to disk, including a process’ loaded DLLs, EXEs, heaps, and stacks.
  • Image a specified driver or all drivers loaded in memory to disk.
  • Hash the EXE and DLLs in the process address space (MD5, SHA1, SHA256.)
  • Verify the digital signatures of the EXEs and DLLs (disk-based).
  • Output all strings in memory on a per-process basis.

Important Tools

  •  WinDbg –Kernel debugger for Windows systems
  •  Muninn – A script to automate portions of analysis using Volatility
  •  DAMM –Differential Analysis of Malware in Memory, built on Volatility
  •  FindAES –Find AES encryption keys in memory
  •  Volatility — Advanced memory forensics framework

Malware Detection

Signature-Based or Pattern Matching: A signature is an algorithm or hash (a number derived from a string of text) that uniquely identifies a specific virus.

Heuristic Analysis or Pro-Active Defense: Heuristic scanning is similar to signature scanning, except that instead of looking for specific signatures, heuristic scanning looks for certain instructions or commands within a program that are not found in typical application programs.

Rule Based: The component of the heuristic engine that conducts the analysis (the analyzer) extracts certain rules from a file and this rules will be compared against a set of rule for malicious code.

Behavioral Blocking: The suspicious behavior approach, by contrast, does not attempt to identify known viruses, but instead monitors the behavior of all programs.

Weight-Based: A heuristic engine based on a weight-based system, which is a quite old styled approach, rates each functionality it detects with a certain weight according to the degree of danger

Sandbox: allows the file to run in a controlled virtual system (or“sandbox”) to see what it does.

Important Tools in malware analysis tutorials
