Cybersecurity experts sound the alarm as researchers uncover MalTerminal, the first known GPT-4 powered malware that embeds advanced AI to craft attacks on the fly. Discovered by SentinelOne’s SentinelLABS team and unveiled at the LABScon 2025 conference, this Windows executable marks a dangerous pivot in cybercrime. Attackers now harness OpenAI’s GPT-4 to generate ransomware or reverse shells dynamically, dodging traditional defenses and ushering in smarter, evolving threats. Dated before November 2023—via a deprecated API—this proof-of-concept could soon turn real-world weapon, experts warn.
With phishing scams and AI tricks on the rise, MalTerminal spotlights how hackers twist helpful tech into harm. SentinelOne analysts hail it as a “qualitative shift” in tactics: Malware no longer stays static; it adapts in real time, complicating detection and response. Python scripts mirror its functions, showing modular design for easy tweaks.
GPT-4 Powered Malware: AI’s Dark Side

Hackers don’t stop at code generation. They poison LLMs in emails with hidden prompts—tucked in invisible HTML—to fool AI security tools. A report details a billing scam that hid exploits via Follina (CVE-2022-30190), dropping PowerShell scripts, killing Defender, and locking in persistence.
Trend Micro tracks a boom in AI site builders like Lovable, Netlify, and Vercel fueling phishing since January 2025. Crooks spin up fake CAPTCHA pages that redirect to credential thieves, masking malice with legit looks and free hosting.
This surge in GPT-4 powered malware lowers barriers for bad actors, turning innovation into easy crime tools. As AI powers both shields and swords, defenses must evolve fast.

Key implications for businesses:
- Run proactive AI security audits now—don’t wait for breaches.
- Test systems against prompt injections and LLM poisoning to stay ahead.
- Boost spending on adaptive AI detectors that match hackers’ speed.
“We’ve entered a new era where AI arms cybercriminals as much as it protects us,” says SentinelOne’s Alex Delamotte. Enterprises ignoring this risk quick obsolescence in the cyber arms race. Stay vigilant: Update tools, train teams, and watch for GPT-4 powered malware signs.
