Can AI Be Hacked? A Look at How AI Systems Are Misused

Artificial Intelligence (AI) is considered the smartest system yet that has come closest to the human thinking capacity. This system is continuously learning and evolving; if we tell you that it can be hacked to give false imprints, it will be a great concern for researchers as well as users. AI attacks exist because the underlying AI algorithms have inherent constraints that attackers can exploit to cause the system to fail. These vulnerabilities, unlike traditional cybersecurity attacks, are not the result of programming or user errors.

AI hacking and misuse have become a big concern for various governments and societies. Here, we will be discussing some vulnerabilities inherent in AI systems. These AI systems, especially ML models, are susceptible to various vulnerabilities due to factors such as their design, the data they utilize, and the environments in which they operate. Common attack vectors include:

1. Adversarial Attacks: These attackers create changes at a microscale to inputs (like adding noise to the image) to trigger outputs which algorithms misdiagnose. For example, a vision component of a self-driving car may read a modified version of a stop sign as a yield sign, resulting in dangerous accidents. It can impact various applications such as self-driving vehicles, face biometric identification, and diagnosis in medicine, causing them to lose their reliability.

2. Data Bombing: Abuse of an algorithm by manipulating the inputs to mislead the algorithm to flag the correct action as incorrect is common. A large amount of biased or incorrect data is fed into the system for bad output. For instance, spam filters can be fed with quasi-spam emails to make spam filters lose their efficacy and yield greater undetected exploitation. Data bombing can impact the repudiation of trust in AI outputs by severely damaging security systems, especially fraud detection systems.

3. Model Inversion and Extraction: This attack occurs when attackers query a model with the intent of harvesting the training data or stealing the model’s architecture and weights. For instance, they may extract sensitive patient data from medical AI systems or replicate a proprietary model for commercial gain. These attacks breach privacy or cause a loss of intellectual property assets. 

4. Backdoor Attacks: When malicious code or training triggers the embedded model during its training or deployment phase for specifically designated activation, it is known as a backdoor attack. For example, a backdoor could be embedded in a facial recognition system to allow unauthorized access upon presentation of a specific image or person. It will sabotage the security system, such as by enabling restricted system access.

5. Prompt Injection Attacks: The crafting of malicious inputs (prompts) to influence large language models (LLMs) to generate harmful outputs is an attack technique. For instance, tricking an AI system to generate malicious content or unintended output. These outputs lead to misinformation, fraud, or reputational damage.

6. Supply Chain Attacks: When third-party libraries, such as datasets or pre-trained models, are compromised throughout the AI development process. For example, if an untrusted source's pre-trained model contains manipulated code, the behavior of the model may change. If the model is extensively utilized, damage will not be limited to the modifier.

How AI Systems Are Misused

In addition to hacking, AI systems can be misused either maliciously or through unintended consequences, potentially leading to harmful effects on the general public. These key misuse scenarios include:

1. Generated Content

Fraud, blackmail, and misinformation campaigns are now easier to execute by using AI tools like deepfake generators or LLMs, which create realistic fake audio, video, or text.

For example, manipulating the audience by creating deepfake videos of politicians and influencers and fraudulently presenting their statements.

Impact: The repercussions include reduced faith in institutions, greater financial fraud, and political instability. Trolling for fake content can have a significant negative impact on a person's self-image and mental health.

2. Bias amplification

AI models based on prejudiced datasets produce inaccurate results, thereby propagating or aggravating societal biases.

For example, AI hiring algorithms may reject applicants based on unjust historical hiring data.

Impact: Discrimination can occur in a job, criminal justice, and financial systems.

3. Privacy Breach and Surveillance

Powerful surveillance capabilities such as facial recognition can enable mass or targeted monitoring of individuals without their permission.

For example, governments or companies may track an individual's activities or behaviors and monitor their thoughts.

Impact: The loss of privacy associated with authoritarian abuse is more likely to occur, resulting in an increased violation of human rights. The consequences of such surveillance extend beyond mere privacy invasions; they can erode trust within communities and foster a culture of fear. This pervasive monitoring not only stifles dissent but also discourages individuals from expressing their true opinions, ultimately undermining democratic principles.

4. Autonomous Weapons

Exemption of human permission for crucial decisions is possible in military technology AI systems due to hacking or misuse, allowing for automated fatal decisions.

For example, hacked AI drones can attack citizens rather than enemy targets.

Impact: Increased internal conflict and ethical problems.

5. Fraud and Scams:

AI can automate phishing, financial fraud, or social engineering to a huge extent. 

Example, AI may create voice and video clones, as well as imitate someone else's identity to authorise fraudulent transactions.

Impact: It can cause heavy financial and reputational losses. 

Mitigation Strategies 

To fight against the hacking and abuse of AI, some strategies can be employed to reduce the effects of the attack: 

• Robust Model Design: Employ adversarial training, regularisation, and input checking to make the models attack-proof. 
• Data Security: Use clean, diverse, and secure training data to avoid poisoning and biases. 
• Access Controls: Restrict model access and enforce strong authentication to avoid unauthorised access to the AI system module. Implementing these strategies can help prevent the hacking of the AI system module.

Conclusion

Like any other computer system, AI is also at risk of being hacked via adversarial attacks, data poisoning, model theft, etc. There have been numerous instances of AI abuse in the shape of deep fakes, biased decisions, and excessive monitoring, which are a serious threat to society. Organizations can address this issue by providing employee training, while individuals can take courses in fields like Cybersecurity, AI and Data Science to help prevent the misuse of AI. Tight technical security measures, ethical regulation, and regulatory guidelines are needed to limit these risks and promote the appropriate use of AI.
