Types of AI Agent Attacks: A Security Team's Taxonomy

A security team running agents in production can already list the ways those agents get attacked: prompt injection, memory poisoning, tool abuse, model tampering, agent-to-agent coercion. The list is not the problem. The problem is that a security architect can recite all five and still not know which ones their detection stack will catch, because the way the field catalogs these attacks says nothing about whether the attack is catchable.

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.

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.

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.

When AI changes the rules, attackers adapt

The dominant narrative around AI in security is one of emboldened defenders suppressing attackers. Yet, not everyone is convinced the future will be so rosy. In a recent Defender Fridays episode, Josh Neil, Co-founder and CTO of Alpha Level, made an argument that cuts against the celebratory mood: as AI makes known attack vectors harder to use, adversaries don't disappear. They adapt. For MSSPs and SOC teams, an adversary that looks like a user is a harder problem than one that looks like malware.

85% of Attacks Leverage RDP for Lateral Movement

Ransomware is pivoting toward faster, more targeted data-extortion models, where encryption is no longer the primary objective. According to WatchGuard’s 2026 cybersecurity predictions, crypto-ransomware will lose ground to models driven by data exfiltration and reputational leverage, lowering the technical bar for threat actors while increasing their attack velocity. This shift has a direct consequence.

Stopping the Agentic Breach: How to Operationalize Your Defense Against Mythos-Speed Attacks

The industry has spent the past few weeks focused on Claude Mythos Preview and the rise of autonomous offensive AI. As outlined in Claude Mythos, Project Glasswing, and the Machine-Speed Security Race, this shift is not only about faster attacks. The same AI-driven acceleration that helps attackers discover weaknesses faster can also help defenders validate exposure sooner. For security operations teams, the challenge is turning that strategic shift into action.

Disrupting Glassworm: Inside CrowdStrike's Takedown of a Developer-Targeting Botnet

On May 26, 2026, at 14:00 UTC, the CrowdStrike Counter Adversary Operations team executed a coordinated takedown of the Glassworm botnet, a global threat targeting software developers through the open-source supply chain. In collaboration with Google and the Shadowserver Foundation, we struck all four of Glassworm's command-and-control (C2) channels simultaneously, severing the operators from their infected machines and their ability to deliver new malicious payloads.

Cyber Attacks on Bank Holidays: Why Your IT Model Is the Weak Link

In the IT world, there is something quietly sinister about a bank holiday. It’s not the holiday itself – who doesn’t love a bank holiday – a long weekend, a reason to grill something in unpredictable weather, the particular pleasure of feeling like you’ve slipped a Monday… The sinister part is structural.

Ransomware Trends, Attack Methods, and Protection Strategies

Ransomware has moved beyond simple malware attacks. It is now operating under a structured business model that disrupts operations, not just systems. Attackers are not depending on phishing or malicious files to deploy ransomware. They instead use compromised identities and existing tools present within environments to move undetected. By the time encryption starts, the attack has already progressed across systems.

9 Top MDR Providers for Operational Technology Environments in 2026

Operational technology security has become one of the hardest problems in cyber defense because the stakes are no longer limited to data loss. When an enterprise email platform goes down, productivity suffers. When an OT environment is disrupted, production can stop, safety margins can narrow, and essential services can be affected. That changes what Managed Detection and Response means.

Supply Chain Attack Targets Laravel-Lang Packages with Credential Stealer

On May 22, 2026, we detected an active supply chain attack against Laravel-Lang. We filed a report with the maintainers immediately. The attacker published malicious version tags across three widely used repositories, injecting credential-stealing code that loads automatically via composer’s autoloader feature. What makes this particularly sneaky is that the malicious code was never committed to the official repos at all.

Laravel-Lang Composer tag-rewrite Supply Chain Attack

On 2026-05-22, an attacker rewrote every repository tag across four Composer packages in the Laravel-Lang ecosystem to point at malicious commits. The affected packages are laravel-lang/lang, laravel-lang/attributes, laravel-lang/http-statuses, and laravel-lang/actions. The rewrite took place on 2026-05-22 into the early hours of 2026-05-23. Every malicious commit makes the same two-file change: one entry added to composer.json, and one new file at src/helpersphp.

Autonomous AI vs Zero-Day Attacks: The New Cybersecurity Shift

For decades, finding a zero-day flaw followed a predictable script: a highly skilled human researcher spent weeks staring at source code, digging for edge cases, and manually stitching together an exploit. In April 2026, Anthropic flipped that script by announcing Claude Mythos. This frontier model didn’t just mark an incremental upgrade; it introduced autonomous, machine-speed vulnerability hunting.

What Is Trust Now, Forge Later (TNFL)? TNFL vs HNDL Attacks Explained

Suppose that the hospital allows a vital software update of its infusion pumps to go through, and all security tests pass. The signature looks valid. The certificate is scrapless. Everything appears legitimate. The update was forged by an attacker who cracked a key that was considered unbreakable just five years ago. The general perception of most individuals is that after encryption or after data is digitally signed, it stays secure indefinitely. That assumption is now perilously outdated.

How Parents Can Detect Smishing Attacks on Their Child's Smartphone Early

Teenagers get dozens of texts every day in this digital age. Some of those come from delivery applications, gaming platforms, schools or friends. However fraudsters are increasingly employing risky smishing attacks to fool kids into clicking on phony links, disclosing passwords or divulging personal information by hiding these typical messages.

SMBs Hit a Cybersecurity Breaking Point as 91% Fear AI-Driven Attacks, Driving Shift to MSP-Led Security Models, WatchGuard Finds

LONDON, May 20 2026 -New research from WatchGuard Technologies, a global leader in unified cybersecurity for MSPs, reveals that while most businesses believe they are adequately staffed, the complexity, speed, and scale of modern threats - especially those powered by artificial intelligence - have outpaced what internal teams can realistically manage. The result is a fundamental shift away from do-it-yourself security toward externally delivered, always-on protection models.

How to Prevent SQL Injection Attacks (2026): 7 Proven Techniques

Your database is one apostrophe away from a breach. SQL injection has been the most common web vulnerability for three consecutive years. The 2025 Verizon DBIR reports it contributed to 12% of all data breaches, up from 9% the year before. In December 2024, a PostgreSQL SQL injection zero-day gave state-sponsored attackers a path into the US Treasury. In 2023, a single campaign used it to steal 2 million job seeker records across 65 websites in one month. The fix has been known for two decades.

Why AI-era attacks demand deterministic defense

The security industry spent a good chunk of early 2026 debating whether Anthropic’s Mythos and OpenAI’s Daybreak are truly dangerous or just good marketing. It's a reasonable debate. But while we're having it, attackers are asking a different question: how do we use tools like this to move faster than defenders can respond?

GitHub Internal Repositories Breached: Source Code and Internal Data Allegedly Exfiltrated in 2026 Supply Chain Attack

In a significant security incident unfolding on May 20, 2026, GitHub confirmed unauthorized access to its internal repositories. The breach involved the exfiltration of sensitive internal source code and organizational data, reportedly totaling around 3,800 to 4,000 private repositories. A threat actor surfaced on underground forums advertising the stolen materials for sale, complete with directory listings of compressed archives and sample verification offers.

WantToCry ransomware remotely encrypts files

SophosLabs analysts investigated WantToCry ransomware attacks that involved the threat actors abusing the Server Message Block (SMB) service for initial access and then exfiltrating files to attacker-controlled infrastructure for remote encryption. The detection surface is significantly reduced because WantToCry operates without local malware execution, and there is no post-compromise activity beyond exfiltrating files and rewriting them to disk.

Mini Shai-Hulud Hits @antv: 323 npm Packages Compromised Through the atool Maintainer Account

An active supply chain attack has compromised 323 npm packages published under the atool npm maintainer account. The wave sweeps the entire @antv data-visualization organization alongside standalone libraries with wide independent adoption: echarts-for-react, timeago.js, size-sensor, and canvas-nest.js. With echarts-for-react pulling roughly 1.1 million weekly downloads, any project that auto-updates these packages is in scope.

The AntV Supply Chain Campaign Expands: Microsoft's `durabletask` PyPI Package Compromised

The ink was barely dry on our coverage of the AntV Shai Hulud supply chain attack when a new compromise surfaced in the Python ecosystem. The target this time is durabletask, an open source Python package associated with Microsoft, used for building durable, fault-tolerant workflow orchestration on top of the Durable Task Framework. The latest safe version of durabletask is 1.4.0, and three known versions have been yanked from the PyPI registry.

Kevin Mandia on AI-Powered Attacks: The Race Just Got Faster | Black Hat | Reach Security

At Black Hat last year, we sat down with Kevin Mandia to talk about what's coming. His take: offense is going to accelerate with AI. Not slow down. Not plateau. Accelerate. When you've run more red teams than practically anyone on the planet, the pattern is clear. Getting into a victim network is already a race. AI compresses those time frames further. The attack surface isn't changing. Misconfigurations, things that slipped, controls that were on and got turned off. The entry point stays the same. AI just makes the race to exploit it faster.

Mini Shai-Hulud: The Most Sophisticated NPM Supply Chain Attack of 2026

On May 11, 2026, the TanStack namespace was hit by a "Mini Shai-Hulud" supply chain attack. Unlike typical attacks, this did not involve stolen credentials; instead, the threat group TeamPCP hijacked the legitimate GitHub Actions release pipeline. This video covers the technical details of the OIDC token extraction, the "Dead Man's Switch" that triggers a rm -rf / upon credential revocation, and the mandatory remediation order you must follow to save your data. We also discuss how to harden your workflow using release-age cooldowns and OIDC pinning.

DDoS Attack Prevention: 15 Best Practices to Stop Attacks in 2026

DDoS attacks cost businesses an average of $6,130 per minute in downtime losses. According to the Indusface State of Application Security 2026 report, 70% of all websites faced at least one DDoS attack in 2025, attacks per website grew 27% year over year, and APIs were targeted 675% more than traditional websites.

Prompt Analysis for AI Attack Detection: Four Signal Categories, Three Blind Spots, One Correlation Layer

At 2:47 PM on a Tuesday, a customer support agent receives a routine ticket asking about return policy edge cases. The agent retrieves a section from your internal policy wiki through RAG to formulate the response. Three weeks earlier, an attacker had planted a hidden instruction in that wiki page. Bedrock Guardrails scored the retrieved context at 0.04 — well within benign range.

DDoS Protection for Healthcare: Uptime, Compliance, and Patient Safety

Healthcare absorbed ~24 million attacks in 2025, a 115% increase year over year, according to the Indusface State of Application Security 2026 report. DDoS alone grew 39% across the sector. But disruption here is not just about lost revenue or downtime. When systems go dark, emergency rooms divert patients, doctors lose access to electronic health records, and appointments are cancelled.

AI Agent Attack Detection: The Complete Framework for Security Teams

It usually starts the same way. The CISO comes back from a board meeting having signed off on agentic AI for production. The SOC lead is told, in roughly that many words, to build detection for the agents. And the security stack she has — CNAPP for posture, EDR on the nodes, container runtime sensors, a SIEM ingesting everything — was architected before AI agents existed as a workload class.

DDoS Protection for SaaS: Keeping Multi-Tenant Platforms Online

SaaS companies face a 20% yearly likelihood of a significant DDoS attack, according to the Indusface State of Application Security H1 2025, underlining the risks to uninterrupted operations. Even brief downtime can have severe consequences. On average, a DDoS attack costs businesses$6,130 per minute in downtime losses. For SaaS platforms, one attack hits every tenant at once, multiplying the SLA breaches, churn risk, and reputational damage across the entire customer base simultaneously.

Detecting Identity Attacks at Scale with Herd Immunity

Modern identity‑based attacks often rely on shared infrastructure and reusable attack frameworks, rather than bespoke tooling built for a single target. Phishing kits and phishing‑as‑a‑service (PhaaS) platforms are the clearest example of this model — and today they are the most prevalent sources of account compromise across organizations of all sizes. Device code phishing illustrates how quickly this model evolves.

Inside the RubyGems Supply Chain Attack: How Mend Defender Caught a Coordinated Flood Before It Spread

On May 11, 2026, Mend Defender flagged more than 120 malicious packages newly published to RubyGems — the standard package manager for the Ruby ecosystem. Within 24 hours, that initial cluster expanded into something far larger: tens of thousands of packages pushed by thousands of attacker-controlled accounts, forcing RubyGems to suspend new account registration entirely while the cleanup got underway.

13 Best DDoS Protection Software in the Market 2026

A DDoS attack costs businesses an average of $6,130 per minute. Beyond service disruption, these attacks often create operational pressure that exposes login systems, APIs, and payment workflows to additional threats such as credential stuffing and account takeover attempts while security teams work to restore availability.

Session on How much of Mythos based attacks can you prevent using modern IDAM techniques?

In this session at ETCISO IDAM Summit 2026, our Founder & CEO Mr. Anirban Mukherji discussed Identity Access Management (IAM), data protection challenges, and AI governance for modern organizations. He covers SSO, MFA, legacy system hurdles, DBT data flows, Shadow AI risks, and practical steps like patch automation, least privilege access, and AI agent controls. Drawing from the Abhimanyu Chakravyuh metaphor, he explains how strong IAM contains breaches. Learn about vendor sovereignty, geopolitical risks, and miniOrange's expertise in IAM, AI security, and privacy.

DDoS Protection for SMBs: Always-On Defense Without the Overhead

SMBs absorbed approximately 894 million attacks in 2025, a 71% year-over-year increase — and DDoS drove 85% of that volume, nearly three times the enterprise rate. API DDoS on SMB platforms surged 1,122% in a single year, according to the Indusface State of Application Security 2026 report. With most SMB security operations run by teams of fewer than five people managing both infrastructure and security simultaneously, cybercriminals increasingly view smaller businesses as soft targets.

DDoS Protection for Education: How Schools, Universities, and EdTech Stay Resilient

Globally, schools and universities now face over 4,300 cyberattacks per week on average, marking a 40% year-over-year increase and making the education sector a prime target for disruptive DDoS attacks. Most educational institutions operate with lean IT teams responsible for infrastructure, user support, and security. This resource constraint makes it difficult to withstand prolonged or application-layer DDoS attacks that can quickly disrupt learning platforms and administrative systems.

Attackers Aren't Hacking In Anymore, They're Logging In

For years, cybersecurity strategy has been built around a simple idea: keep attackers out. Stronger perimeters. Better firewalls. More advanced endpoint protection. Smarter email filtering. But the latest insights from the Microsoft Digital Defense Report tell a very different story. Attackers aren’t breaking in. They’re logging in.

How Fidelis Deception Helps Defend Against AI-Accelerated Intrusions

AI-powered attackers are faster and more systematic than ever. But they still trust what they see. Deception technology controls what they see. 87% of security leaders say AI-related vulnerabilities grew faster than any other risk in 2025 44% year-over-year rise in exploitation of public-facing applications in 2025 300K+ AI platform credentials exposed via infostealer malware on dark web in 2025.

DDoS Protection for Insurance: Always-On Defense for Claims, Quotes & APIs

According to the State of Application Security 2026, insurance platforms saw a 115% increase in attacks per website. DDoS attacks per site rose by 143%, targeting critical periods like claim processing and policy renewals. In an industry built on trust, availability is a business promise. Even brief downtime disrupts revenue and compliance, making always-on DDoS protection a core requirement for insurance resilience.

TanStack Npm Packages Compromised Inside The Mini Shai Hulud Supply Chain Attack

On May 11, 2026, between 19:20 and 19:26 UTC, 84 malicious npm package artifacts were published across 42 packages in the @tanstack namespace. The packages were not published by an attacker who stole credentials; they were published by TanStack's legitimate release pipeline, using its trusted OIDC identity, after attacker-controlled code hijacked the runner mid-workflow. The malicious versions spread to Mistral AI, UiPath, and dozens of other maintainers within hours.

Top tips: How you can shrink the time between a vulnerability and an attack

Top tips is a weekly column where we highlight what’s trending in the tech world and share ways to stay ahead. This week, we’re looking at how the gap between a vulnerability and an attack is shrinking rapidly. A vulnerability is discovered. It could be a small bug, a missed update, or a gap in how a system is configured. It gets reported, documented, and sometimes even publicly disclosed. For a long time, there used to be an extended window between discovery and attack.

How Attackers Use Developer Machines to Breach the Software Supply Chain - May 07, 2026

In April, three major supply chain campaigns hit npm, PyPI, and Docker Hub in just 48 hours, and while the ecosystems were different, the objective was the same: steal credentials from developer environments and CI/CD pipelines. The malware targeted API keys, cloud credentials, SSH keys, GitHub tokens, npm tokens, environment variables, and more, turning developer machines and build systems into high-value credential vaults for attackers.

Zero-Day Attacks and How to Protect Your Systems from Them

Zero-day attacks are one of the most serious threats in cybersecurity. They target unknown software weaknesses and can cause damage before anyone is aware of the issue. It is important to understand how these attacks work to better protect systems and data. A Zero-day attack exploits a software vulnerability that is unknown to the developer but already known to attackers. The attacker tries to exploit the vulnerability before the concerned team can identify and apply a patch to fix it.

2026 Public Sector Cyber Attacks and Data Breaches

In 2026, the public sector continues to face numerous cyber attacks, with data breaches often exposing sensitive information, disrupting essential services and undermining public trust. From municipal governments to federal agencies, public sector organizations of all sizes face challenges from threat actors exploiting outdated systems, human error and expanding digital footprints. These incidents are more than isolated security failures.

What is Credential Theft? How Attacks Work, Their Business Impact, and How to Prevent Them

Almost every system today, including cloud platforms, SaaS tools, and enterprise apps, relies on identity to control who gets in. That shift has made login credentials one of the most valuable things an attacker can get their hands on. A single compromised account can be enough to move through an entire network, access sensitive data, and stay hidden for weeks without triggering an alarm.

New RMM Abuse Exposes Remote Access Blind Spots in U.S. and EU Companies

Can your SOC prove when a trusted remote access tool becomes unauthorized access? That is the challenge behind the latest RMM abuse targeting companies in the U.S. and Europe. Attackers are using phishing pages to deliver legitimate remote access software, making malicious activity look like routine IT work. For CISOs, the risk is clear: if the team cannot see how the tool entered the environment, what executed, and where the connection went next, containment slows down and business exposure grows.

How Telecom Operators Can Secure OSS/BSS Stacks

Telecom security conversations still orbit around the network. Firewalls, signaling protection, DDoS mitigation-those get budget and attention. Meanwhile, the systems that handle billing, subscriptions, and customer data often sit in the background, treated as operational plumbing rather than a primary risk surface.

The UK Government's Open Letter on AI Cyber Threats Underscores the Need for Measurable Security

A recent open letter from the UK government on AI-driven cyber threats highlights a clear shift in the threat landscape. Cyberattacks are no longer constrained in the same way by human expertise, as advanced AI models can now help identify vulnerabilities, generate exploit code, and increase the speed and scale of attacks.

Payment Infrastructure Is Now Part of the Attack Surface

Every payment creates a moment of trust. A customer enters card details, a gateway approves or rejects the transaction, fraud checks run in the background, and sensitive data moves between systems in seconds. When that process works, it feels invisible. When it fails, the damage can reach far beyond a lost sale.

PhantomRaven Wave 5: New Undocumented NPM Supply Chain Campaign Targets DeFi, Cloud, and AI Developers

Mend’s security research team has identified a previously undocumented fifth wave of the PhantomRaven campaign, an ongoing NPM supply chain attack that has been stealing developer credentials and secrets since August 2025. This new wave uses a fresh command-and-control server, 33 new malicious packages, and a more sophisticated three-stage payload chain.

How to Stop Digital Impersonation Attacks: Why Email Authentication Alone Isn't Enough

Phishing reports and customer complaints are not early warning signals. By the time they arrive, attackers have already built the infrastructure. Lookalike domains are live, credential harvesting pages are indexed, and the exposure window is open. To stop digital impersonation attacks, organizations need to shift detection to the infrastructure preparation stage, before distribution begins.
