The Rising Threats in the Open-Source AI Supply Chain
As the global artificial intelligence race accelerates, one platform stands at the epicenter of innovation and risk—Hugging Face. Once a niche hub for machine learning developers, Hugging Face has become a global force, housing nearly 1.8 million AI models today. What’s even more astonishing is the rate of growth—this doubling of scale took just nine months, signaling both a leap in capability and a dramatic expansion of the AI supply chain. But with rapid innovation comes new dangers. Open-source AI introduces a spectrum of vulnerabilities, including software bugs, embedded backdoors, and poisoned training data. The platform’s open nature has attracted model providers from around the globe, including both trusted institutions and unknown actors.
Recognizing the escalating threat, Cisco Security has joined forces with Foundation AI’s threat intelligence team to launch Cerberus, a real-time scanning and defense system tailored to Hugging Face. Cerberus inspects AI models for malicious code, licensing issues, and geopolitical concerns, feeding insights directly into Cisco’s security products. This automated surveillance ecosystem now integrates with Cisco Secure Endpoint, Secure Email, and Secure Web Gateway. The result is an intelligent firewall that detects and blocks compromised models before they can wreak havoc. Cerberus operates in a closed loop: it monitors model updates, assesses risk, logs metadata, and distributes threat intelligence back to Cisco’s enforcement platforms.
Cerberus doesn’t stop at basic code scanning. Its detection capabilities include file obfuscation, unsafe deserialization, system access attempts, and models attempting to establish unauthorized network connections. Cisco now uses these insights to actively prevent downloads, email attachments, or filesystem interactions with unsafe models. As the AI landscape continues to evolve with new agent-based tools and decentralized workflows, Cisco and Foundation AI are positioning themselves at the forefront of AI supply chain security. In a world where models are being deployed faster than ever, Cerberus offers an essential buffer—keeping innovation flowing while minimizing exposure to cyber threats.
What Undercode Say:
Hugging Face as a Double-Edged Sword
The rise of Hugging Face has been both a triumph and a dilemma for the AI world. On one hand, it’s a beacon of innovation, democratizing access to top-tier machine learning models. On the other, it’s a growing vector for cyber threats. Its open-source nature is precisely what makes it so powerful—and so risky. With thousands of contributors uploading unchecked models from across the globe, the platform has become a petri dish for experimental and, sometimes, malicious code. This is a classic case of open innovation meeting the brutal reality of cybersecurity.
AI Supply Chain Is the New Attack Surface
Traditional cybersecurity focused on endpoints, networks, and applications. But in 2025, the battleground has expanded into the AI supply chain. Every model, dataset, and training script introduces new risk. This isn’t theoretical—there are already real-world cases of model backdoors and poisoned datasets slipping into production environments. AI models are now being treated as live software artifacts, capable of executing code and modifying systems. That alone is a monumental shift in how security must be approached.
Cisco’s Move: A Strategic Masterstroke
Cisco’s partnership with Foundation AI and the rollout of Cerberus could be a game-changer. By creating real-time integrations into Secure Endpoint, Email, and Web Gateway products, Cisco has effectively established the first industrial-scale defense mechanism for open-source AI. It’s no longer about scanning code before it runs—now, it’s about continuously monitoring the evolving state of AI models across public platforms. This is continuous cybersecurity at the model layer, which represents a major advancement.
Cerberus: A Watchdog for the Modern Age
Cerberus brings a suite of deep inspection capabilities that go far beyond static analysis. It analyzes pickled files (a known vector for Python-based exploits), flags licensing violations, and checks for communication attempts with external systems. The inclusion of metadata analysis adds a forensic layer that helps trace threats back to their origin. This isn’t just about detection—it’s about comprehensive traceability and policy enforcement at scale.
Open Source Licensing and IP Risks
One under-discussed threat in the AI pipeline is licensing. Many developers unknowingly use models governed by restrictive licenses like GPL or AGPL, which can create major intellectual property conflicts when those models are deployed commercially. Cerberus flags these risks in real time, allowing businesses to remain compliant without sacrificing speed. This functionality alone may save companies from costly legal headaches in the future.
Geopolitical Risk Adds Another Layer
AI is no longer just about technology—it’s deeply geopolitical. Cerberus flags models originating from vendors based in politically sensitive regions, such as DeepSeek. With rising tensions between global superpowers and AI becoming a tool of influence, identifying and restricting imports from potentially adversarial territories has become an urgent necessity. Cerberus does this in a systematic, automated way, reducing human error and decision latency.
Speed Is the Currency of AI Security
With the AI arms race accelerating, defenders must move faster than ever. Models are published and adopted in days—not months. Cerberus addresses this velocity with automated updates, constant scanning, and seamless integration with Cisco’s wider security suite. No manual intervention is needed. That level of automation is the only way to match the tempo of AI development today.
The Human Factor and Agent-Led Development
Modern development is no longer purely human-led. Autonomous agents are generating code, training models, and pushing them live. This drastically changes the risk model. It’s not just about human error anymore—it’s about algorithmic unpredictability. Cerberus adapts to this new reality by treating every model update as a potential threat vector, analyzing it in a machine-speed feedback loop.
🔍 Fact Checker Results:
✅ Hugging Face has over 1.8 million models as of mid-2025
✅ Cisco and Foundation AI have built Cerberus to monitor model threats in real time
✅ Licensing violations and geopolitically sensitive models are part of Cerberus’s scanning framework
📊 Prediction:
As AI continues to evolve, expect major cybersecurity vendors to follow Cisco’s lead, integrating AI-specific threat detection into their ecosystems. The open-source model space will likely be regulated in the next 12 to 18 months, either through government policies or industry self-regulation. Platforms like Hugging Face may soon be required to enforce stricter contributor verification, code review mechanisms, and licensing disclosures. Cerberus might just be the blueprint for the next generation of AI security infrastructure.
