Warlock Exploits SharePoint Flaws to Disable Security Tools and Deploy Ransomware

Oct 03, 2026 Vulnerability / Critical Infrastructure
The suspected China-linked threat actor known as Warlock is still continuing to weaponize Microsoft SharePoint vulnerabilities, likely both old and new , in attacks targeting organizations in Portuguese- and Spanish-speaking countries. The activity, observed by the Symantec and Carbon Black Threat Hunter Team, has hit critical infrastructure, government, and education organizations. "In the past two months, Longlegs has attacked at least four organizations, including two critical infrastructure operators (a water utility and a telecommunications provider), a regional government body, and a university," the Broadcom-owned cybersecurity unit said . "Victims were in Portuguese- and Spanish-speaking countries, spanning Europe, Africa, and Latin America."  Warlock, also tracked as Gold Salem, Longlegs, and Storm-2603, gained prominence in mid-2025 in connection with the zero-day exploitation of the "ToolShell" SharePoint flaws to deploy ransomware on ...

The State of Cybersecurity in 2026: Key Segments, Insights, and Innovations

Oct 03, 2026 Identity Security / Artificial Intelligence
Featuring: Cybersecurity is being reshaped by the expansion of cloud infrastructure, AI, distributed systems, and increasingly complex digital environments. As organizations manage more identities, devices, data, and internet-facing infrastructure, security is shifting toward continuous visibility, control, and the ability to respond to risk at scale. This report examines how core areas of cybersecurity are evolving in response to that shift. Across identity security, telemetry management, human security, endpoint management, human risk intelligence, exposure management, email and domain security, connected device security, AI-native security operations, and cloud security, it explores how organizations are adapting to threats that increasingly move across systems, identities, and infrastructure rather than targeting a single point of failure.

GitLab Patches Critical 9.9 AI Gateway Flaw Allowing Command Execution on Self-Hosted Servers

GitLab Patches Critical 9.9 AI Gateway Flaw Allowing Command Execution on Self-Hosted Servers

Oct 02, 2026 Vulnerability / Application Security
A critical flaw in GitLab's AI Gateway could let a logged-in user with Duo Agent Platform access run commands on the gateway under certain conditions, GitLab  said in an advisory . The gateway is the service that connects a GitLab instance to AI models, and only organizations that host their own gateway need to act. The flaw is fixed in gateway versions 19.2.4, 19.3.2, and 19.4.1. The flaw is tracked as  CVE-2026-90970 . GitLab disclosed it on October 2 and rated it critical, with a CVSS score of 9.9 out of 10. GitLab runs AI Gateways for its customers and has already fixed them. Customers on GitLab.com, GitLab Dedicated, and self-managed instances that use a GitLab-hosted gateway do not need to act, the company said. Self-managed customers can instead  host their own gateway , an option GitLab offers for keeping AI request and response data inside the customer's own environment. GitLab strongly recommends that those customers update immediately. It sent that gui...
