In August 2026, Sophos analysts began investigating a series of Managed Detection and Response (MDR) cases that involved ClickFix-style lures and resulted in the deployment of a Python-based tunneling implant. Instead of a typical ClickFix lure that instructs victims to open the Run dialog box, these lures direct users to open a Windows Terminal window. This ClickFix variation is known as ‘TerminalFix’. TerminalFix is not linked to a specific threat group or a single campaign.

This article was first published on LinkedIn. Consider a cybersecurity alert for a potentially malicious PowerShell script that downloads and runs a file. An AI agent in a security operations center (SOC) can handle it by picking from a fixed set of actions: close the alert as benign, collect more evidence, or send it to an analyst. Before letting the agent act on such alerts, the SOC needs to know how often it picks correctly and whether its confidence helps identify its mistakes.

On September 27, 2026, Citrix disclosed eight vulnerabilities affecting NetScaler Application Delivery Controller (ADC) and NetScaler Gateway. Two of these vulnerabilities are critical (CVSS score of 9.5) and can allow an unauthenticated remote attacker to execute code: Citrix has observed exploitation against unmitigated NetScaler deployments, and the U.S.

On September 25, 2026, reports emerged that Kiteworks (formerly Acellion) emailed customers that law enforcement alerted them about an “imminent” cyberattack on Kiteworks systems, possibly caused by exploitation of a zero-day vulnerability. Kiteworks reportedly advised customers to shut down servers between 02:00 and 08:00 UTC on September 26, if not sooner, as a “precautionary” measure.

For decades, we believed that if could hear someone’s voice on a phone call or see them on a video call, they were who they said they were. What if that’s no longer true? This article is part of an ongoing series from Sophos frontline security operations specialists, sharing the expertise they use to strengthen our industry-leading Managed Detection and Response (MDR) service and defend customers against evolving AI Era threats.

AI uncertainty is not a strategic reason to wait; it is a strategic imperative to build adaptable organizations that can innovate confidently, govern risk proportionately, and respond effectively as technology and threats evolve. Every few weeks, the AI conversation seems to reset around a new warning. A model demonstrates an unexpected capability. An autonomous agent behaves in a way its designers did not anticipate. A new forecast describes how quickly AI could transform work, security or society.

On September 14, 2026, Cisco disclosed a vulnerability in Cisco Secure Email Gateway. CVE-2026-76461 is a critical (CVSS score of 9.8) SQL injection flaw in the email parsing functionality of Cisco AsyncOS Software. Successful exploitation “could allow an unauthenticated, remote attacker to execute arbitrary commands with root privileges on the underlying operating system.” Cisco confirmed exploitation of the vulnerability in the wild, and the U.S.

MSPs are no longer simply being asked to manage technology; increasingly, customers are expecting them to provide cybersecurity leadership, deliver compliance programs, and guide security investment. Sophos’ 2026 MSP Perspectives Report reveals how demand for cybersecurity leadership, maturing compliance offerings, and the battle for scale are all shaping the managed services market.

Sophos Next-Gen SIEM, now generally available as part of Sophos Fusion, brings security operations and compliance together through shared context. For years, the cybersecurity industry has blurred the lines between XDR and SIEM. As capabilities converged, organizations were left trying to connect separate security operations and compliance solutions, often moving the same data between different tools, workflows, and teams.
