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 gang's time from initial access to draining data out of a Veeam server is shockingly fast; after which the attackers went on to deploy actual ransomware in less than a day.
The CE giant released its investigative findings regarding a March cyberattack that resulted in data exfiltration affecting its Japanese operations.
The ransomware-as-a-service platform just rolled off the assembly line, also targets Windows, and uses Golang for cross-platform capabilities.
Now may be a good time to find good deals on insurance coverage for ransomware and security incidents.
