Ransomware encrypts or steals data to disrupt operations and extort victims, making backups, access controls, and incident response essential.

Background for this topic.
Ransomware is malware used to deny access to systems or data, usually by encrypting files and demanding payment for decryption. Many operations also steal sensitive information and threaten to publish it, so an attack can create both an availability crisis and a privacy or disclosure risk. Initial access may involve phishing, stolen credentials, exposed remote services, or exploitation of unpatched vulnerabilities; attackers may then move through the network before deploying the payload.
Defenses should combine vulnerability management, phishing-resistant authentication where practical, endpoint and network monitoring, and backups that are isolated from routine administrator access and regularly tested for recovery. Organizations should also limit privileges and segment critical systems to reduce the blast radius. An incident requires rapid containment, preservation of forensic evidence, restoration from known-good backups, and assessment of notification, legal, and regulatory obligations. Threat intelligence can help identify relevant criminal infrastructure or tactics, but it does not replace sound access control, patching, detection, and recovery practices.
The hacktivist group is ramping up its activities and ready to assault governments and businesses with escalating capabilities.
Titaniam’s ‘State of Data Exfiltration & Extortion Report’ also finds that while over 70% of organizations had heavy investments in prevention, detection, and backup solutions, the majority of victims ended up giving into attackers' demands.
Like a hydra, every time one ransomware gang drops out (REvil or Conti), plenty more step up to fill the void (Black Basta).
