Ransomware
What is Ransomware?
Ransomware is malware that blocks access to systems or data, usually by encrypting files, and demands payment in exchange for restoration.
Examples
- An employee opens a malicious attachment from a phishing email, and the malware spreads through shared drives and encrypts business files.
- Attackers exploit a vulnerable remote access service, gain administrative access, disable backups, and then deploy ransomware across the network.

Few cyber threats feel as disruptive as ransomware. A phishing email, stolen credential, or exposed service can lead to a situation where staff suddenly cannot open files, critical systems stop working, and the organization is faced with an urgent demand for money. The technical problem becomes a business crisis very quickly.
Ransomware stands out because it attacks availability directly, but the damage often goes further. Lost access can interrupt operations, delay services, create safety concerns, and damage customer trust. In many cases, attackers also steal data before encryption begins, which turns the incident into a confidentiality problem as well.
Summary 📝
Ransomware is malware used to deny access to systems or data and pressure victims into paying for restoration. Its real danger comes from operational disruption, possible data theft, and the speed with which a technical issue becomes a business crisis. Strong defense depends on prevention, containment, resilient backups, and a prepared incident response capability.
