Question 2

Why is it important to understand which ransomware variant was used in the attack?

Answer 2

• Behavior Understanding

• Decryption Possibilities
  
  • sometimes decryption tools are available for specific ransomware types
• Vulnerability Exploitation
  
  • identifying the ransomware helps in understanding which vulnerabilities were exploited and need to be patched
• IOC (Indicator of Compromise) Identification
  
  • identifying the type helps in effectively searching for these IOCs across the network to ensure complete eradication
• Forensic Analysis
  
  • knowing the ransomware type aids in forensic analysis, helping understand the attack vector, impact, and potential data breach extents
• Informing Stakeholders
  
  • important for both internal and external communication, especially when dealing with legal, regulatory, and public relations aspects
