AI opens the door to make many tasks easier in life... including creating ransomware. The barrier of entry for threat actors is now significantly lowered, and by dynamically generating on the fly, it weakens detection techniques like file prevalence. Behaviour detections are a must and EDR needs to evolve capabilities to detect this as early in the chain as possible. https://lnkd.in/edD5Xxc3

🚨 AI is coming for your data. This new ransomware is leveraging OpenAI to generate malicious code while it's on your network. Start focusing on how you're going to defend against this. Check out what Aaron B. has to say about it:

A ransomware that talks back? That’s PromptLock for you. ESET found this new strain using an AI model—the same kind of tech behind chatbots—to write and run its own malicious code on the fly. Basically, it’s like ransomware got a mini hacker brain, dynamically cooking up scripts to grab and lock your files in real time. If AI can boost attacks this way, how do we prepare? The threat’s evolving fast; our defenses should too. What’s your take on AI’s role in cybercrime escalation?

ESET’s discovery of PromptLock (classified as Filecoder.PromptLock.A), the first AI-powered ransomware, feels like a real turning point. Even though it began as an academic proof of concept, the fact it can use a local AI model to generate malicious scripts on the fly shows how quickly attackers could raise the stakes. For me, the big takeaway is clear: we need to stay ahead with AI-aware detection, stronger behavioral analytics, and closer collaboration across the industry. PromptLock may not be in the wild today, but it’s a glimpse of what’s coming. https://lnkd.in/d4FV8UJg

Ransomware The Dark Side of AI – Emerging Threats and How to Stay Secure - A dark digital vault with glowing binary code flowing into a shadowy figure controlling strings—symbolizing AI-driven ransomware manipulating sensitive data. https://lnkd.in/eypWAaVn

First AI Ransomware ‘PromptLock’ Uses 𝗢𝗽𝗲𝗻𝗔𝗜 𝗴𝗽𝘁-𝗼𝘀𝘀-𝟮𝟬𝗯 𝗠𝗼𝗱𝗲𝗹 for Encryption : A new ransomware has been identified, which is believed to be the first-ever ransomware strain that leverages a local AI model to generate its malicious components. PromptLock leverages Lua scripts generated from hard-coded prompts to enumerate the local filesystem, inspect target files, exfiltrate selected data, and perform encryption. https://lnkd.in/gdmKijcm

🧠⚠️ AI meets ransomware: Researchers have flagged 'PromptLock' — malware that hijacks large language models to steal data, encrypt files & auto-generate ransom notes. A chilling reminder for research teams deploying AI tools: rigorous prompt security is no longer optional. Stay informed, stay protected. 🔍🛡️ #AIinResearch #DataSecurity #MarketResearchInsights
