With clean forensic images secured, your security analysts can now dissect the malware safely inside an isolated sandbox environment. Knowing how the adversary gained entry—whether through a phishing email, a vulnerable Remote Desktop Protocol (RDP) gateway, or an unpatched web application—is vital to ensuring they do not waltz back in through the backdoor. ✅

• Execute static analysis: Inspect the binary’s code structure, embedded strings, and imported APIs without actually running the malicious executable.
• Conduct dynamic behavioral analysis: Run the malware inside a sandbox environment to observe its registry modifications, network callbacks, and file system changes.
• Hunt for Lateral Movement: Search Active Directory logs and network traffic for Pass-the-Hash attacks or unauthorized PowerShell scripts.
• Identify Patient Zero: Trace back through log files to pinpoint the exact initial vector and user account compromised.
• Extract Indicators of Compromise (IoCs): Compile a comprehensive list of malicious IP addresses, domain names, file hashes, and registry keys.

Phase 4: Eradication and System Rebuilding 🛠️

You cannot simply decrypt files and call it a day; if the underlying vulnerability remains unpatched, the ransomware will strike again within hours. Eradication requires completely purging the adversary’s persistence mechanisms, backdoors, and compromised credentials from your entire enterprise architecture. 📈

• Revoke all credentials: Force a mandatory enterprise-wide password reset and invalidate all active session tokens and Kerberos tickets.
