AI vs. AI: Why GenAI Malware Is a Wake-Up Call for Small Businesses

Click here to view/listen to our blogcast.

When we talk about AI in cybersecurity, most people think about the good guys – AI tools helping detect, analyze, and prevent attacks faster than any human could. But a recent discovery by Deep Instinct’s generative AI assistant, DIANNA, reminds us that cybercriminals also use AI – sometimes to terrifying effect.

DIANNA recently analyzed a highly obfuscated and modular malware sample dubbed BypassERWDirectSyscallShellcodeLoader – believed to be created using generative AI tools like ChatGPT or DeepSeek. This was no ordinary malware. It was custom-built to evade detection, bypass traditional defenses, and deliver payloads in stealth mode. And it worked.

What Makes This Threat So Dangerous?

Unlike common malware that relies on known patterns or reused code, this strain was:

• LLM-generated, meaning it could be crafted by attackers with limited coding expertise.
• Heavily obfuscated, hiding its true function even from trained analysts.
• Capable of evading modern defenses, using techniques like direct system calls and ETW bypasses.
• Designed to adapt, making it harder to create static signatures for detection.

This marks a major turning point: the automation of malware development, supercharged by AI.

Why Small Businesses Should Be Especially Concerned

Many small businesses still operate with limited cybersecurity protections – no 24/7 monitoring, no real incident response plan, and minimal investment in threat detection tools. Here’s what makes them prime targets:

• Limited IT staff: No in-house security expert to identify and respond to subtle threats.
• Unpatched systems: Small businesses often lag behind on updates, leaving known vulnerabilities exposed.
• Flat networks: Without segmentation, one infected system can compromise the entire organization.
• Minimal endpoint protection: Many rely on outdated antivirus software that can’t handle sophisticated threats like AI-generated malware.

What You Can Do Right Now

To protect your business against threats like this, you don’t need a million-dollar budget – just a smart plan and the right support:

• Adopt AI-enhanced endpoint protection
  Use tools that leverage behavior-based detection, not just signature scanning.
• Implement a layered defense strategy
  Firewalls, DNS filtering, application control, and strong email protection work better together.
• Update and patch regularly
  Ensure that operating systems and software are up to date to reduce exploit risk.
• Train your staff
  Employees are often the weakest link. Make cybersecurity awareness part of your culture.
• Have a response plan in place
  Know what to do if something gets through – contain, communicate, and recover quickly.

Final Thoughts

Cybercriminals are now using AI to create smarter, stealthier, and more targeted attacks. DIANNA’s discovery isn’t a one-off – it’s a glimpse into the future of cybercrime. Small businesses can’t afford to ignore this trend.
