Using AI Coding Tools? You Might Get Hacked. Check This Out Right Now

 

 

Lately when I look at my developer colleagues at work, they're saying they can't get anything done without AI coding tools like ChatGPT or GitHub Copilot. I see them hit a wall with code, immediately ask an AI for help, and watch complex functions just materialize with a single "can you build this for me?" It's pretty amazing, honestly kind of envious. But recently I've been hearing that this could be a serious security threat. It's scary enough that I can't just ignore it.

For those who have no idea what AI coding tools are

Don't worry if you're not a developer. Think of AI coding tools like this: when a developer is writing program code, an AI sits beside them and automatically suggests "try doing it this way next." It's kind of like how writers use grammar checking software—developers are increasingly relying on these AI tools.

The big ones are GitHub Copilot, Cursor, Claude, and ChatGPT. If you're a developer these days, you're definitely using at least one of these. So yeah, if these get compromised, it's genuinely scary.

So why does this become a hacking gateway?

The key issue is something called "Package Hallucination." Sounds complicated, but let me break it down. Sometimes when AI is writing code, it'll recommend "you should use this library for this feature." A library is basically a bundle of pre-written code that other people have made, and developers can just grab it and use it—way easier, right?

Here's the problem: the AI sometimes confidently recommends library names that don't even exist. It's hallucinating—imagining things that aren't real. The creepy part? When the AI gets it wrong, it says it with total confidence. It sounds completely legit at first glance.

So what do hackers do? They identify library names that the AI frequently suggests by mistake, and then they actually create fake libraries with those names—packed with malicious code—and upload them. The moment a developer trusts the AI and installs it, the malware gets into their computer.

Why should I care? Trust me, it affects you

You might think, "I'm not a developer, why should I care about this?" But consider this: every app you use, every online store, every company internal system, every banking app—someone developed all of that. What if that developer used an AI tool and installed a malicious library?

That malware sneaks into the completed app or service. This is called a Supply Chain Attack. It's a method that contaminates the actual supply process of creating a product. You didn't click any suspicious link yourself, but the service you're using is already infected. That's the situation you could end up in.

What's honestly more terrifying is that there's basically nothing you can do to stop it, no matter how careful you are. You just downloaded the official app from the official app store, but the app itself is already compromised from the start.

This can actually happen to you—let me walk you through a scenario

Say a developer at Company A is building an employee time tracking app. They ask an AI, "What library do I need to build the employee location tracking feature?" The AI confidently replies, "Try using locatrack-utils."

The developer installs it without suspicion. But that library? It's fake—made by a hacker. Hidden inside is code that secretly leaks employee personal information to an external server. By the time they realize something's wrong after the app goes live, hundreds of employees' information has already been stolen.

This isn't science fiction. Similar incidents have actually been reported multiple times, and when researchers tested AI tools, the rate at which they recommended non-existent packages turned out to be pretty high.

So what can we do about it? Let me break it down by job type

📌 If you're a developer—just double-check one more time before hitting enter

Get into the habit of searching for library names that the AI recommends directly in official package repositories (npm, PyPI, Maven, etc.). Be suspicious if the download count is suspiciously low, if it was created way too recently, or if there's no admin info.

And it's important that your whole team understands that AI recommendations ≠ verified solutions. The AI can be wrong, and hackers are precisely targeting those gaps.

📌 If you're not a developer but work in tech—just check your company's security policy once

It's worth asking whether your company's dev team has any security guidelines about using AI coding tools. If they don't, you could casually suggest it to the IT or security team. Something like "do we have a package validation process when using AI tools?"

Also, if you notice anything weird with company systems, don't just brush it off—report it to IT right away. One small anomaly caught early can prevent a massive data leak.

📌 If you're a regular user—don't be lazy about app updates

Supply chain attacks are hard for you to prevent directly, but there's still something you can do. When app developers discover and fix problems, they release updates. Updating quickly means you spend less time using infected versions.

And the basic rule of not installing apps from sketchy sources never changes. Stick with the habit of only getting apps from official app stores (Google Play, Apple App Store).

Frequently Asked Questions (FAQ)

Q: Should I just stop using AI coding tools altogether?

A: Not at all. The issue isn't really the AI coding tools themselves—it's developers blindly trusting what the AI says without verifying anything. AI tools massively boost productivity, but you just need to make a habit of directly checking any recommended libraries or packages in the official repository. It's not about ditching the tool, it's about using it smarter.

Q: How can I tell if an app I use has been hit by a supply chain attack?

A: Honestly, it's super difficult for regular users to catch it themselves. Usually the app developer or security researchers discover it first and go public about it. So it helps to keep up with security news occasionally, or follow the official social media and announcements of apps you use frequently. If you notice weird things like sudden battery drain or skyrocketing data usage, try deleting and reinstalling the app.

Q: Is this kind of attack actually happening in Korea right now?

A: Yes, Korea's not an exception. Korean developers use the same global AI coding tools, and malicious packages get uploaded to repositories worldwide, so Korean developers aren't safe either. In fact, Korean security research teams are already monitoring this issue seriously and have started running education programs for companies.

It's a great era where AI has become a reliable assistant to developers. Work gets faster and easier, which is awesome. But we should remember that convenience always comes with a shadow. Use AI, but don't blindly trust it. That one small habit can be the starting point to protecting yourself, your company, and the services you use.
