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.

New malware, even better social engineering chops The FBI and a host of international cyber and law enforcement agencies on Tuesday warned that Scattered Spider extortionists have changed their tactics and are now breaking into victims' networks using savvier social engineering techniques, searching for organizations' Snowflake database credentials, and deploying a handful of new ransomware variants, most recently DragonForce. …
Look over there! Amidst its own failure to fix a couple of bugs now under mass exploitation and being abused for espionage, data theft, and ransomware infections, Microsoft said Monday that it spotted a macOS vulnerability some months ago that could allow attackers to steal private data. Redmond reported the bug to Cupertino, which issued a fix back in March.…
