The vulnerability flood is here. Here's what it means - and how to prepare

We can't control the pace of AI-driven vulnerability discovery, but we can control how fast we respond. Last week, Thomas Ptacek published a piece arguing that vulnerability research is cooked. His thesis: AI agents are about to drown us in a steady stream of validated, exploitable, high-severity vulnerabilities, faster than anyone can patch them. But from where I sit, the more urgent question isn't whether the flood is coming, but whether the infrastructure we depend on can absorb it.

We let OpenClaw loose on an internal network. Here's what it found

Following our article on the challenges posed by agentic AI, we gave OpenClaw access to one of our legacy networks In my previous article on OpenClaw I wrote: “Even the most ‘risk-on’ organizations with deep AI and security experience, will likely find it challenging to configure OpenClaw in a way that effectively mitigates the risk of compromise or data loss, while still retaining any productivity value.” The Red Team here at Sophos took that as ‘challenge accepted’, s

Adobe Reader zero-day vulnerability in active exploitation

On April 7, 2026, a security researcher described an Adobe Reader zero-day vulnerability that has been exploited since at least December 2025. The vulnerability allows threat actors to execute privileged Acrobat APIs via specially crafted malicious PDF files that execute obfuscated JavaScript when opened. Exploitation allows attackers to steal sensitive user and system data and to potentially launch additional attacks and remotely execute code.

Amazon GuardDuty enhances detection efficacy with Sophos threat intelligence

Amazon GuardDuty enhances detection efficacy with Sophos threat intelligence Amazon has integrated Sophos threat intelligence into Amazon GuardDuty, expanding the breadth and accuracy of malicious threat detection for customers running workloads on Amazon Web Services (AWS). Threat intelligence is a cornerstone of effective cyber defenses. The higher the quality of intelligence, the faster security teams can detect, investigate, and block malicious activities.

The High Cost of Low Trust: Our Commitment to Radical Transparency

Only 5% of organizations fully trust their cybersecurity providers. Let’s do better. In our industry, trust isn't an abstract concept. It’s the currency of cybersecurity – the foundation of every partnership we build and every protection we provide. However, a recent independent, vendor-agnostic survey of 5,000 cybersecurity decision-makers across 17 countries reveals a stark reality: we’re facing a trust crisis.
