How AI Agents Can Break Into Your Website in 90 Seconds

Your website has a login page, a contact form, maybe a customer portal. It works fine. Customers use it every day without issues. So it is secure, right?

Here is the problem with that assumption: "it works" and "it is secure" are two completely different things. And a new generation of AI-powered attack tools is making that distinction painfully clear, painfully fast.

This is the second post in our security series. The first one covered the risks hiding in AI-generated code. This one is about the other side of the equation — what happens when AI is the one doing the attacking.

The Speed of AI-Powered Attacks

Traditional hacking takes time. A human attacker needs to manually probe your website, test different entry points, try various techniques, and piece together how your system works. Depending on the complexity of the target, that process can take hours, days, or weeks.

AI agents don't have that limitation.

Shannon is an open-source AI pentesting tool that autonomously scans web applications for vulnerabilities, analyzes the code, and then executes real exploits to prove they work. It doesn't just flag potential issues like a traditional scanner — it actually breaks in, the same way a real attacker would.

On the XBOW benchmark, a standardized test for measuring how well tools can find and exploit web application vulnerabilities, Shannon achieved a 96.15 percent success rate. For context, human penetration testers averaged 85 percent on the same benchmark across 40-hour engagements. Shannon does its work in a fraction of that time.

When pointed at OWASP Juice Shop, a deliberately vulnerable test application used for security training, Shannon discovered over 20 critical vulnerabilities in a single automated run. That included complete authentication bypass, database extraction through injection attacks, privilege escalation, and server-side request forgery that could reach internal networks.

The tool is designed for authorized security testing, not criminal use. But the underlying technology is not unique to Shannon. If a freely available, open-source tool can do this, you can be certain that bad actors are building and using similar capabilities — without the ethical guardrails.

What AI Attackers Look For

AI-powered attack tools don't think like humans. They don't get bored, they don't get distracted, and they don't stop after the first few attempts. They systematically work through a checklist of known vulnerability types, and they do it across every part of your application simultaneously.

Here is what they are scanning for:

SQL Injection

If your website has a search bar, a login form, or any field where users enter text, an AI attacker will try injecting database commands through it. If the input is not properly validated, those commands execute against your database. The attacker can read your entire customer list, modify records, or delete data.

Cross-Site Scripting (XSS)

This is when an attacker injects malicious code into your website that runs in your customers' browsers. It can steal login sessions, redirect users to fake pages, or capture information they type into forms. AI tools test hundreds of XSS variations in seconds.

Exposed APIs

Modern websites rely on APIs — the behind-the-scenes connections between your frontend and your data. If those APIs don't require proper authentication, or if they return more data than they should, an AI scanner will find them and pull everything it can access.

Authentication Bypass

AI tools test for weak password policies, predictable session tokens, missing account lockout mechanisms, and flawed password reset flows. They also check whether admin pages or internal tools are accessible without proper credentials.

Outdated Dependencies

Every website is built on a stack of third-party libraries and frameworks. When those components have known vulnerabilities and haven't been updated, AI scanners cross-reference them against public vulnerability databases instantly. An outdated WordPress plugin, an unpatched JavaScript library, a server running old software — these are all easy entry points.

Why AI Attackers Have the Advantage

The uncomfortable truth is that AI-powered attacks have structural advantages over human defenders.

They are fast. What takes a human security tester hours or days, an AI agent can cover in minutes. It can test thousands of input combinations, scan every endpoint, and try every known exploit technique without pausing.

They are persistent. An AI agent doesn't take breaks. It can run continuously, retrying different approaches and adapting its strategy based on what it learns about your system's responses.

They scale effortlessly. A human attacker can target one website at a time. An AI attacker can target thousands simultaneously. This is the key point that changes the risk calculation for small businesses.

They learn from patterns. AI tools trained on databases of known vulnerabilities recognize common code patterns and configuration mistakes. They don't need to "figure out" your system from scratch — they recognize what they are looking at and know exactly which attacks to try.

"We're Too Small to Be a Target"

This is the most dangerous assumption a business owner can make, and AI attacks are the reason it no longer holds.

When attacks were manual, there was some truth to it. A human hacker with limited time would focus on high-value targets — banks, retailers, healthcare companies. Going after a local accounting firm or a regional services company didn't make economic sense for the attacker.

Automated AI attacks changed that math entirely. When it costs an attacker essentially nothing to scan and probe your website, every website becomes worth trying. These tools don't discriminate based on company size. They scan IP ranges, crawl the web, and test everything they find. If your site has a vulnerability, it will be found — not because someone targeted you specifically, but because a bot tried every site on the internet and yours was one of the ones that let it in.

The data reflects this shift. Small businesses now account for a disproportionate share of successful breaches, not because they are targeted more often than large enterprises, but because they are less prepared when the automated probes come knocking.

What's Actually at Risk

When an AI agent successfully exploits a vulnerability in your website, the damage depends on what your site is connected to. But for most businesses, the answer is: more than you think.

Customer data. Names, email addresses, phone numbers, and potentially payment information. If your site has a customer portal or stores any personal information, it is a target.

Business credentials. Database passwords, API keys for third-party services, admin login credentials. Once an attacker has these, they can access your connected systems — your email marketing platform, your payment processor, your cloud storage.

Financial data. Invoices, transaction records, pricing information. For businesses that handle client finances — accountants, bookkeepers, financial advisors — a breach here isn't just embarrassing, it's potentially career-ending.

Your reputation. A data breach notification to your customers erodes trust in a way that marketing budgets can't easily rebuild. For service businesses that run on relationships and referrals, this is often the most lasting damage.

What a Reasonable Security Posture Looks Like

You don't need a Fortune 500 security budget to meaningfully reduce your risk. But you do need to move beyond "it works fine" as your security standard. Here is what baseline protection looks like.

Validate Every Input

Every form field, search bar, URL parameter, and API endpoint on your website should validate and sanitize the data it receives. This is the single most effective defense against injection attacks and XSS. If you are working with a developer, ask them specifically whether input validation is in place.

Lock Down Authentication

Use strong password hashing (bcrypt or argon2, not MD5 or SHA1). Implement account lockout after repeated failed login attempts. Use HTTPS everywhere. If you have an admin panel, make sure it is not accessible from the public internet without additional protection.

Manage Your API Keys

API keys and database credentials should never appear in your source code. They belong in environment variables or a secrets manager. If your code is on GitHub, make sure the repository is private, and run a secrets scanner to check that nothing sensitive has been committed.

Keep Dependencies Updated

Set a recurring reminder — monthly at minimum — to update the libraries and frameworks your website depends on. Many of the vulnerabilities that AI tools exploit are already patched in newer versions. You just need to install the update.

Monitor for Unusual Activity

Even basic monitoring can catch an attack in progress. Watch for spikes in failed login attempts, unusual traffic patterns, or unexpected data access. Many hosting platforms offer built-in monitoring tools that require minimal setup.

Get a Professional Assessment

If your website handles customer data, financial information, or anything that would be damaging if exposed, get a security assessment. Not the kind where someone runs an automated scanner and sends you a PDF — the kind where a real person looks at your code, your configurations, and your architecture with an understanding of how modern attacks actually work.

The Arms Race Is Real

AI is making both sides of cybersecurity faster and more capable. Defenders are using AI to detect threats and patch vulnerabilities more quickly. Attackers are using AI to find and exploit those vulnerabilities before patches are applied. The businesses caught in the middle — the ones running websites and applications without thinking much about security — are the ones getting hurt.

This isn't something you can ignore and hope for the best. The tools being used to probe your website don't care how big your company is, what industry you are in, or whether you think you have anything worth stealing. They test everything, and they are getting better at it every month.

The good news is that the defenses are not complicated. They require attention, not genius. And they cost far less than dealing with a breach after the fact.
