**Deck**: A newly identified ENCFORGE ransomware strain is built not just to lock files, but to encrypt AI model weights, vector indexes, and training data, striking at the core assets of modern machine intelligence. Deployed via a critical Langflow vulnerability and linked to operators behind earlier ‘agentic’ attacks, the campaign shows how AI infrastructure itself is becoming a battlefield. We explain how the attack works, who is at risk, and what this means for states and firms racing to dominate AI.

A new wave of ransomware is going after the crown jewels of modern computing: the AI models themselves. Security researchers have uncovered ENCFORGE, a ransomware family designed specifically to encrypt model weights, vector indexes and training datasets—assets that underpin everything from recommendation engines to defense simulations and financial risk systems.

Unlike traditional ransomware, which typically scrambles documents, databases or backups, ENCFORGE focuses on the artifacts that make AI systems intelligent. Model weights are the learned parameters that embody months of training, often at multimillion-dollar compute costs. Vector indexes are the structures that let models search and retrieve relevant information quickly. By encrypting these elements, attackers are not just disrupting IT; they are disabling the decision-making engines that organizations increasingly rely on.

According to technical analyses released by cybersecurity firms, ENCFORGE is being deployed in the wild through a critical vulnerability in Langflow, a platform used to build and orchestrate AI workflows. The flaw, tracked as CVE‑2025‑3248 with a severity score of 9.8, allows a pre-authentication compromise that leads to code execution on affected hosts. Once inside, attackers escalate privileges to root, then systematically seek out AI-related directories and repositories before launching encryption.

Experts have linked the operators behind ENCFORGE to the same group responsible for an earlier “agentic” attack campaign that exploited AI agents and orchestration tools to move laterally inside networks. That linkage suggests a focus on environments where AI is not a side project but a core operational layer—cloud providers, large enterprises, research labs and, increasingly, government and defense systems experimenting with autonomous decision-support.

For data scientists and engineers, the human impact is stark. A successful ENCFORGE infection can wipe out months of experiments, tuned models and carefully curated training corpora in hours, replacing them with ransom notes and the threat of data theft. Teams that thought of AI infrastructure as a high-value but niche asset now have to reckon with it as a primary target; restoring service may require retraining from scratch, which is slow, expensive and sometimes impossible if original data can’t be reconstructed.

Strategically, the campaign exposes an underappreciated vulnerability in national AI ambitions. Governments talk about “AI sovereignty” and “trusted AI stacks,” but many of the tools that glue systems together—frameworks like Langflow or platforms like ServiceNow’s AI modules, which are also facing a critical sandbox-escape flaw—are built on complex, rapidly evolving software with large attack surfaces. A separate, newly disclosed vulnerability in the ServiceNow AI Platform (CVE‑2026‑6875) allows unauthenticated attackers to break out of sandboxes and run arbitrary code, reinforcing how exposed operational AI environments can be.

ENCFORGE shows that adversaries have learned the same lesson policymakers have: control over AI systems is a strategic asset worth targeting. Disrupting an opponent’s logistics AI, intelligence-analysis models or industrial optimization systems can yield outsized effects compared with wiping ordinary office files. For companies in critical sectors—energy, finance, logistics, defense manufacturing—the line between a cyber incident and a national-security problem is thinning.

“Once attackers realized that model weights are effectively the DNA of an AI capability, it was only a matter of time before they wrote malware to hold that DNA hostage,” one senior security architect observed after reviewing the ENCFORGE analysis. The campaign turns abstract talk about AI risk into something much more concrete: if your model is gone, so is the competitive edge or operational advantage it delivered.

The next indicators to watch are whether ENCFORGE starts to appear in incident reports from major cloud providers and Fortune 500 firms, whether state-linked threat actors adopt or imitate its techniques, and whether regulators move to treat AI model stores and orchestration tools as critical infrastructure. A confirmed attack on government or defense-related AI environments would mark a new phase, where ransomware is not just a criminal business model but a lever in geopolitical competition over who controls the smartest systems.
