The AI Agent Attack Kill Chain: Which Stages You Can Actually Detect

The early stages of an AI agent attack are silent. The poisoning, the hijacked intent, the reconnaissance: none of it executes, so none of it produces a runtime signal, and the kill-chain instinct every security team runs on says exactly the wrong thing here: break the earliest link. There is no early link to break. You cannot detect a stage that emits nothing.

Tool Call Analysis for AI Attack Detection: Reading What Rides Inside the Call

A compromised agent doesn’t make a single call it isn’t allowed to make. It queries a table it’s authorized to read, calls a tool it’s authorized to use, sends to a domain that’s on the allowlist. Every call is legal. The attack is in the values it passes, and your tool-call log records all of it as a clean day’s work. A tool call has two layers. Almost every tool you run reads the first one: the call itself: which tool, in what order, at what rate.

Brand Impersonation Protection: How to Detect, Disrupt, and Stop Impersonation Attacks

Brand impersonation protection helps enterprises detect, disrupt, and stop impersonation attacks where criminals imitate trusted brands, websites, apps, domains, ads, or digital journeys to deceive users and steal credentials, data, money, or access. The goal is not to stop every fake asset from ever appearing. That is not realistic.

Businesses have NO IDEA how bad AI attacks can be

There are two types of companies: those who have been compromised and those who will be. Mid and small businesses are walking into this reality without understanding what AI has changed. On The Cybersecurity Defenders Podcast, David Chernitzky, CEO and co-founder of Armour Cybersecurity, explains why the gap between how large organizations understand AI-driven threats and how smaller ones do is widening fast.

Defending Against the Next Generation of Agentic Attacks

The attack lifecycle is compressing. Frontier AI models like Anthropic’s Mythos and OpenAI’s GPT-5.5-Cyber can help bad actors research vulnerabilities, test approaches, adapt code, and change delivery methods at machine speed and scale. That reduces the time, skill, and coordination needed to move from vulnerability discovery to active attack. When attacks behave this way, security needs to operate in real time with full visibility and context across the attack path.

NGINX Under Active Attack: CVE-2026-42945 and CVE-2026-9256 Put Your Infrastructure at Risk

NGINX administrators are facing back-to-back emergency patch cycles. Within days of each other, two critical heap buffer overflow vulnerabilities were disclosed in the same NGINX component, both capable of crashing worker processes and enabling remote code execution on systems without ASLR. If your organization runs NGINX in any capacity, these need immediate attention.

Free Gift Fallacy: How Attackers Harvest Credit Cards via Fake Surveys

The classic 'survey reward' scam is back and hitting harder than ever. KnowBe4 Threat Labs is tracking a massive, high-volume campaign that is not only impersonating a wide array of trusted global brands across retail, logistics, and healthcare, but is using hundreds of newly registered domains (NRDs) and sophisticated psychological priming to fly past traditional security defenses.

How to detect HTTP/2 abuse in Apache web server logs

Apache HTTP Server is one of the most popular web servers in use today for engineering teams, and its prevalence naturally makes it a frequent target for attackers. In May 2026, the Apache Software Foundation patched CVE-2026-23918, a high-severity double-free vulnerability in Apache 2.4.66’s mod_http2 module. For teams not using Apache’s MPM prefork, the vulnerability would enable an attacker to crash worker processes or achieve remote code execution (RCE) in some specific cases.
