Artificial intelligence has become one of the most important tools in modern cybersecurity. It helps spot threats faster, automate responses, and strengthen defenses overall. At the same time, though, it’s giving cybercriminals new ways to create more advanced and dangerous attacks.

The latest development in this space isn’t an active threat yet, but it’s enough to raise eyebrows across the security world. Researchers have found proof that a new kind of ransomware, powered by AI, is being built, and the possibilities are troubling.

Meet PromptLock, a Glimpse into Where Ransomware Is Headed

Two researchers from ESET, Peter Strýček and Anton Cherepanov, have revealed what they’re calling a proof of concept: a type of ransomware they’ve named PromptLock. While it isn’t being used in active attacks just yet, PromptLock gives us a preview of where things could be headed once hackers start using generative AI more often.

Here’s what makes PromptLock different. Instead of being written manually, it’s guided by AI prompts that produce Lua scripts. This code can scan a system, look for valuable files, exfiltrate stolen content, and then encrypt what’s left behind. That’s standard behavior for ransomware, but with AI involved, the process becomes far more automated and accessible to less experienced attackers.

Though PromptLock hasn’t been found in the wild so far, the fact that something like this is being tested should make businesses pay attention. It proves that AI can be used to assist with writing malware, and it lowers the barrier to entry into cybercrime.

Why Automated Malware Shouldn’t Be Dismissed

It might be tempting to shrug this off as something that’s still far off. But here’s the issue: what’s theoretical today can turn into a widespread problem much faster than most expect.

Using AI-generated scripts, attackers no longer need advanced coding abilities to build working ransomware. That shift means organizations of any size could be targeted, including those that were once considered too small to matter.

If this kind of tool becomes widely available, attackers won’t need to be skilled coders. They’ll just need access to the right AI prompts. That changes the game significantly.

What This Means for Cybersecurity Teams

While cybercriminals are finding new ways to attack, AI is also offering defenders better tools to fight back, if they’re intentional about using them.

Here are some ways organizations can prepare:

Improve threat detection. Several modern security tools now use machine learning to identify unusual or suspicious behavior before things get worse.

Focus on training. Employees continue to be the first line of defense, and keeping them aware of phishing scams, suspicious activity, and password best practices is key.

Use a layered defense. Combining things like endpoint protection, firewalls, frequent software updates, and solid backup practices creates a stronger shield.

Stay ahead with information. Discoveries like PromptLock aren’t just stories; they’re early warnings. Knowing what’s on the horizon helps you act sooner.

It’s Time To Get Ahead of the Curve

The threat landscape is changing, and it’s not slowing down. AI-powered malware will become more advanced, easier to access, and harder to detect. That doesn’t mean panic, it means planning.

The best time to build a strong cybersecurity foundation is before disaster strikes. Staying alert to new tactics and investing in better protection could save your organization from major consequences later.

Hackers are already experimenting with what’s next. The question is: what are you doing to stay ahead of them?
