For the past year, the ransomware conversation has centered on concentration: a handful of dominant RaaS operations controlling most of the damage, and a shrinking pool of active groups fighting over the same territory. The State of Ransomware Q2 2026 report from Check Point Research shows that picture starting to shift. The leaders are still winning, but […] The post The State of Ransomware Q2 2026 appeared first on Check Point Research.

Microsoft has disclosed that Storm-1175, a financially motivated threat actor linked to China, has deployed a previously undocumented ransomware strain called StormEncryptor. The use of StormEncryptor marks a shift from the adversary's previous use of Medusa ransomware, the Microsoft Threat Intelligence Team said. "StormEncryptor is written in C++ and appends the file name extension .encrypted
Microsoft Threat Intelligence examines DeadLock ransomware, an emerging financially motivated operation distinguished by its use of decentralized infrastructure to support victim communications, negotiations, and data leak operations alongside double extortion tactics used to pressure victims. The post DeadLock ransomware: Breaking down a Rust-based encryptor with decentralized recovery infrastructure appeared first on Microsoft Security Blog.
Microsoft Defender automatically isolated a compromised QNET endpoint in 128 seconds, stopping a multi-stage attack before the payload could persist or spread. The post 128 Seconds to disruption: Microsoft Defender stops ransomware at QNET appeared first on Microsoft Security Blog.
OpenAI models going rogue, the first documented agentic ransomware operation, and an emergent AI-driven supply chain threat made for a packed July roundup
Written by: Kelli Vanderlee, Stuart Carrera For years, the cybersecurity industry's understanding of software supply chain compromise has been anchored by a few watershed events, including Russian cyber espionage actor ICE RELIC’s (formerly known as APT29) 2020 compromise of SolarWinds and North Korean cyber espionage actor UNC4736's 2023 compromise of 3CX. However, Google Threat Intelligence Group (GTIG) has been tracking growth in threat activity targeting open source software repositories to…

The ransomware economy has been rewired. Meet the eight ransomware groups driving the shift, from affiliate breakaways to AI-assisted attacks based on Group-IB Threat Intelligence.
The Chaos ransomware group uses new malware "msaRAT" that hijacks browsers. The malware doesn't communicate directly with C2 but connects through the browser. It enables arbitrary command execution while hiding the attacker's IP from victims via WebRTC over TURN.
An unauthenticated attacker can chain two WordPress Core vulnerabilities, CVE-2026-63030 and CVE-2026-60137, to achieve remote code execution against affected WordPress installations. Multiple security firms have confirmed active in-the-wild exploitation within days of public disclosure, and public proof-of-concept exploits are circulating.Key takeaways:Two WordPress Core vulnerabilities, CVE-2026-63030 and CVE-2026-60137, can be chained together to achieve pre-authentication remote code execut…
Huntress has observed Akira ransomware affiliates in action, as well as ReadText34 and INC ransomware being deployed.
Four Microsoft SharePoint Server vulnerabilities are under active exploitation, prompting CISA to issue a hardening alert. An additional high-severity flaw recently patched adds pressure for organizations running on-premises deployments.Key TakeawaysCISA confirmed active exploitation of three on-premises SharePoint Server vulnerabilities (CVE-2026-32201, CVE-2026-45659, CVE-2026-56164), used to gain unauthorized access, establish remote code execution, steal IIS machine keys and deploy malware …
SonicWall patched two recently exploited zero-day vulnerabilities in its SMA 1000 Series secure remote access appliances which may have been chained for unauthenticated remote code execution.Key takeawaysCVE-2026-15409 and CVE-2026-15410 are a pair of exploited vulnerabilities that may have been chained together to allow for code execution on SonicWall SMA1000 series appliances. Zero-day exploitation of these vulnerabilities has been observed and confirmed by SonicWall. Patches and indicators o…
Ransomware is the final act, not the first move. Learn how attackers use access brokers and trusted tools to infiltrate your environment—and how to stop them early.
Ransomware, BEC, and social engineering attacks increasingly start with a simple login, not malware. See the five threat patterns IT and security teams need to watch for, and how to catch them early.
Huntress has observed a series of strikingly similar intrusions beginning with CitrixBleed 2 exploitation, employing novel local privilege escalation techniques, and ending in Dragonforce ransomware.
Ransomware-as-a-Service turned ransomware into a scalable criminal business. Learn how the model works, why it creates so much disruption, and where defenders can shut attacks down before encryption starts.
A recent investigation uncovered an Akira affiliate abusing a website owned by file-sharing app LimeWire for data exfiltration. Here's how the attack unfolded.
Two recent incidents involving The Gentlemen ransomware show the use of defense evasion tactics, including logs being cleared and attempts to add antivirus exclusions.
The ransomware name on the ransom note doesn't tell the full story. See how RaaS affiliates drive initial access, persistence, and exfiltration and what defenders should watch for.
Executive Summary Since our February 2026 report on AI-related threat activity, Google Threat Intelligence Group (GTIG) has continued to track a maturing transition from nascent AI-enabled operations to the industrial-scale application of generative models within adversarial workflows. This report, based on insights derived from Mandiant incident response engagements, Gemini, and GTIG’s proactive research, highlights the dual nature of the current threat environment where AI serves as both a so…
