The RansomLord NG version now has option to dump process memory of the targeted Malware
Why memory dump?
Performing static analysis on E.g. DarkRace ransomware MD5: cfc7b4d9933483c25141ba49b4d5755e
using for example Detect It Easy (DIE) static analysis tool reveal no links or other interesting strings.
However, loading MalDump.dmp file generated by RansomLordNG into DIE we may quickly find interesting strings like:

Another sample HydraCrypt MD5: c2f30cd537c79b6bcd292e6824ea874e reveals no interesting strings when doing basic static analysis. Again, using RansomLordNG MalDump feature we quickly find interesting strings like: "[email protected] - SUPPORT " etc
RansomLordNG leverages code execution vulnerabilities and saving process memory to disk prior to termination of the Malware pre-encryption. This may be useful as we can possibly avoid unpacking, anti-debugging techniques or fully executing the malware.
The MalDump feature is optional and can be toggled to enabled=1 or disabled=0
