Sure! Here’s the translation:
Artificial intelligence (AI), once a futuristic technological promise, is now a cornerstone in global industrial, scientific, social, and economic development. However, as it consolidates as critical infrastructure, it also becomes a primary target for malicious actors. This is evidenced by multiple recent incidents and cybersecurity analyses that warn of an alarming increase in attacks directed at AI models, their frameworks, data, and infrastructure.
In this context, cyberattacks against AI not only seek to breach systems but also to alter decisions, steal intellectual property, or manipulate results for fraudulent or geopolitical purposes. Therefore, the security of artificial intelligence is no longer just a technical issue, but a strategic one.
Why are AI models so attractive to attackers?
AI models work with massive volumes of information, including personal, financial, or health data. In sectors like medicine, defense, energy, or banking, an induced failure could lead to anything from fraud to massive disruptions.
Moreover, these systems are often connected via APIs to other services, rely on external data for training, and in many cases, are publicly exposed for use as a service. All of this increases the attack surface.
Main Vectors and Forms of Attack on AI
The following are the most common and dangerous attack methods against artificial intelligence systems:
🧪 1. Data Poisoning
The attacker manipulates training data to introduce biases or deliberate errors that alter the model’s results. This is especially critical in models that learn continuously or in automated environments.
🎯 2. Adversarial Attacks
These involve modifying inputs—like images, text, or audio—in a way that is nearly imperceptible to humans but induces classification errors in the model. They have been used to bypass facial recognition, antispam, or malware detection systems.
🧬 3. Model Inversion
This allows sensitive information to be inferred from the model’s responses, such as reconstructing faces or retrieving personal data from users, which is particularly concerning in models trained with private information.
🔍 4. Model Extraction
This involves replicating a model’s internal behavior by analyzing its outputs, without needing direct access to the code or data. It allows the cloning of commercial models and undermining trade secrets.
🚫 5. Evasion Attacks
These modify inputs in such a way that the model does not detect malicious activities. For example, in an antimalware system, making an infected file classified as benign.
🧠 6. Model Control
Through vulnerabilities in its deployment or infrastructure, attackers could take control of the model, use it as an attack platform, or even generate controlled responses (e.g., in manipulated chatbots).
🦠 7. Malware in Infrastructure
Servers hosting and processing models are also vulnerable to infections. Malware in these environments can disrupt critical services or leak trained models and confidential data.
Real Cases That Raised Alarms
- Tay, Microsoft’s Chatbot (2016): manipulated by users on social media to spread racist and misogynistic messages in under 24 hours. An early example of how a poorly trained model can become a reputational threat.
- Leaking of Meta’s LLaMA Model (2023): the model was distributed without authorization before its official release. This highlighted the need to protect models as intellectual property assets.
- OpenAI Under Attack (2024): researchers documented attempts to induce GPT-3 and GPT-4 to reveal sensitive training information through carefully crafted prompts.
- UK Energy Company (2019): a €220,000 scam using voice deepfake to impersonate the CEO and authorize an urgent bank transfer. An attack that combined AI and social engineering.
How to Protect Artificial Intelligence?
AI security requires a multi-layered protection approach that combines traditional cybersecurity with new strategies specific to machine learning environments:
- Shield Training Data: ensure that sources are reliable, audit datasets, and detect poisoning attempts.
- Monitor API Access: apply query limits, robust authentication, and abuse detection systems.
- Audit Models and Their Decisions: use techniques like explainable AI (XAI) to detect biases or anomalous responses.
- Secure Physical and Virtual Infrastructure: servers running AI should meet security standards equivalent to those of critical systems.
- Simulate Adversarial Attacks: as part of testing before deployment and during operation.
- Use frameworks like MITRE ATLAS™: an increasingly adopted tool that classifies and analyzes specific attack techniques against AI.
Conclusion: A New Frontier in Cybersecurity
Artificial intelligence is redefining what is possible, but it has also opened a new battlefield for cybersecurity. Attacks not only compromise data but also automated decisions, the reputation of organizations, and public trust.
In light of this new reality, companies, governments, and research centers must treat the security of their AI models as an essential component, not an accessory. By 2025, protecting AI will no longer be an option: it will be an urgent necessity.
