Ransomware is malicious software that encrypts an organization’s files or systems, rendering them inaccessible until a ransom is paid — with no guarantee that payment restores access or prevents the stolen data from being leaked regardless. Modern ransomware operations frequently combine encryption with data theft and extortion.

**How It Works:**
Ransomware typically gains initial access through a phishing email, a compromised credential, or an unpatched vulnerability, then spreads across a network before encrypting critical systems — often timed for maximum disruption, such as over a weekend or during a critical business period.

**Real-World Pattern:**
An employee clicks a malicious link in what appeared to be a routine vendor communication. Days later — after the attacker has already moved through the network undetected — critical systems are encrypted simultaneously, forcing the organization into manual, paper-based operations while incident response begins.

**How ProtectYourData Defends Against It:**
Ransomware readiness training focuses on recognizing the phishing and credential-theft patterns that precede an attack, combined with the Ransomware Readiness Drill and Tabletop Breach Response Exercise to test organizational response before a real incident occurs.
