Ransomware Groups: Inside the Operations of Cybercrime Syndicates

Ransomware groups are organized cybercriminal entities that specialize in encrypting victims’ data and demanding payment for its release. These groups operate like sophisticated businesses, complete with customer service portals, affiliates, and negotiation teams. Notorious groups such as LockBit, Conti, and BlackCat have targeted governments, corporations, and critical infrastructure worldwide.

These attacks are often launched via phishing, unpatched vulnerabilities, or remote desktop protocol (RDP) exploitation. Understanding the structure, tactics, and motivations of ransomware groups is essential for developing strong cybersecurity defenses and incident response strategies.
