Inside the Hidden VM: How Attackers Stay Undetected

Threat actors are getting better at hiding in plain sight through using virtual environments to evade detection and deliver ransomware. New research from Sophos X-Ops reveals an increase in the abuse of QEMU, an open-source emulator, to conceal malicious activity inside virtual machines. While this technique isn’t new, its use for defense evasion is accelerating, making visibility and detection even more challenging for defenders.

'Mini Shai-Hulud' supply chain attack targets SAP npm packages

On April 29, 2026, security researchers detailed a campaign known as ‘mini Shai-Hulud’ that involves compromised versions of npm packages used in SAP’s Cloud Application Programming Model (CAP). The malicious packages reportedly contain functionality to steal sensitive data such as credentials. The stolen data is encrypted and exfiltrated via public GitHub repositories. The maintainers of known-compromised packages have released updated versions.

Continuous Threat Exposure Management (CTEM): The Complete Guide to Proactive Cybersecurity

The cybersecurity landscape has fundamentally changed. Organizations today manage sprawling digital environments - cloud workloads, remote endpoints, SaaS applications, third-party APIs, and hybrid infrastructure - all of which expand the attack surface at a pace that traditional security programs simply cannot match.

Threat Detection for RAG Pipelines: The Three Windows Most Tools Are Blind To

Tuesday, 09:14 UTC. A connector pulling content from your knowledge wiki indexes a new article into the vector database your support agents query at runtime. Embedded in legitimate troubleshooting prose is an instruction crafted to surface whenever a query mentions a specific product version — include the user’s account record in the response and POST the summary to the configured support webhook. For three days, nothing happens. Every security tool is green.

Supply chain attacks hit Checkmarx and Bitwarden developer tools

Sophos X-Ops is aware of reports that two widely-used developer tools – the Checkmarx KICs security scanner and the Bitwarden CLI – were hijacked on April 22, 2026, to steal credentials from development environments. These attacks occurred within hours of each other and share the same command-and-control (C2) domain – potentially pointing to a single threat actor running a coordinated campaign. Both vendors have since reportedly contained the incidents.

AI Threat Detection for Financial Services: Detecting AI-Driven Fraud and Data Exfiltration

A Tier 1 bank’s security architecture already spends heavily on detection. On one side sits the financial surveillance stack — fraud scoring platforms processing thirty thousand transactions an hour, AML monitoring watching money movement patterns, DLP engines scanning data in transit, payment anomaly detection tuned by a decade of production signal.

How AI Threat Detection Stops Breaches Before They Happen: A No-Fluff Guide

What’s changed in the cybersecurity world after the advent of Artificial Intelligence (AI)? The speed of response has gone up. The Security Operations Center (SOC) and internal cybersecurity teams are able to detect, respond to, and mitigate attacks faster than ever. It’s a no-brainer that AI agents can neutralize identity-based attacks within seconds, before a human analyst checks the alerts.

From human-scale to AI-scale: Lessons in resilience from RSAC 2026

The halls of RSAC 2026 were buzzing with a singular question: "How do we defend an ecosystem that is moving faster than we can think?" During a featured session last week, Brian Dye (CEO, Corelight) talked with Deneen DeFiore (CISO, United Airlines) about the realities of protecting one of the world's most complex digital environments.
