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.

Threat actors associated with the DragonForce ransomware have been observed using a custom Go-based remote access trojan (RAT) called Backdoor.Turn to conceal command-and-control (C2) traffic inside Microsoft Teams relay infrastructure
Eset Links Group's Growth to Integrated Endpoint-Killing ToolsEset researchers say the rapidly growing Gentlemen ransomware operation differentiates itself by supplying affiliates with a standardized EDR-killer suite that disables security tools, quickly incorporates newly disclosed vulnerable drivers and helps scale attacks across multiple regions worldwide.
And one of those basics is focusing on sectors where a ransomware disruption creates immediate pressure to pay up, like with healthcare.
DragonForce hid for months by routing malware traffic through Microsoft Teams infrastructure, masking C2 activity and evading network detection. DragonForce ransomware operators hit a major U.S. services firm and stayed hidden for one to two months by routing their command-and-control traffic through Microsoft’s own Teams relay servers. Symantec’s threat hunters tracked the custom backdoor they […]

The Gentlemen ransomware used infostealer credentials, AI tools, and affiliates to hit 483 victims across 66 countries in under a year. The Gentlemen surfaced as a ransomware operation in September 2025 and by June 13, 2026 had listed 483 victims on their dark-web leak site, 380 of them in 2026 alone. That makes them the […]
