Incident Response Ransomware Series: Part 1

This three-part blog post provides an introductory overview of ransomware: defining what ransomware is, detailing an infection kill chain (dropper, persistence, enumeration, encryption), common spread vectors (phishing, exploit kits, SMB lateral movement, RDP), variations (MBR encryption, extortionware, fileless techniques), representative families and sample hashes, and the multi-stage Emotet→TrickBot→Ryuk campaign; it is primarily educational and aimed at detection, protection, and prevention.
