Sophos has been named a Leader in the IDC MarketScape for Worldwide Modern Endpoint Security for Enterprises 2026, recognizing the strength of our prevention-first approach and stopping AI-era threats as early as possible.

TerminalFix and Lorem Ipsum Loader enable covert tunneling

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.

Jev's Paradox: The hidden cost of cheap AI decisions

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.

Citrix NetScaler vulnerabilities (CVE-2026-88771, CVE-2026-88772) in active exploitation

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.
