AI system vulnerabilities refer to weaknesses that can be exploited by malicious actors to compromise the integrity, confidentiality, or availability of AI systems.
Adversarial attacks, specifically, have a significant impact on AI systems. These attacks involve the intentional manipulation of input data to deceive or mislead the system, leading to incorrect or unexpected outputs. Adversarial attacks can exploit vulnerabilities in the learning algorithms, data preprocessing, or deployment infrastructure of AI systems. They can result in severe consequences such as misclassification, unauthorized access, or even system failure.
Understanding and mitigating these vulnerabilities is crucial to ensure the robustness and security of AI systems in the face of adversarial threats.
Common Strategies for Adversarial Attacks
To continue our exploration of the vulnerabilities in AI systems, let’s now delve into the common strategies employed in adversarial attacks.
Adversarial attacks exploit the weaknesses of AI systems by introducing malicious inputs that can deceive the models and cause them to make incorrect predictions. These attacks can take various forms, such as adding imperceptible perturbations to images or noise to audio signals, aiming to fool the AI into misclassifying or misinterpreting the data.
Examples of adversarial attacks include the Fast Gradient Sign Method (FGSM), which modifies input features by leveraging the gradient information, and the Carlini and Wagner attack, which optimizes a perturbation to maximize the model’s misclassification rate.
The impact of these attacks on AI systems is significant, as they can undermine the reliability and trustworthiness of the models, potentially leading to severe consequences in critical applications.

Report Finds Top AI Developers Lack Transparency in Disclosing Societal Impact
Stanford HAI Releases Foundation Model Transparency Index
A new report released by Stanford HAI (Human-Centered Artificial Intelligence) suggests that leading developers of AI base models, like OpenAI and Meta, are not effectively disclosing information regarding the potential societal effects of their models. The Foundation Model Transparency Index, unveiled today by Stanford HAI, evaluated the transparency measures taken by the makers of the top 10 AI models. While Meta’s Llama 2 ranked the highest, with BloomZ and OpenAI’s GPT-4 following closely behind, none of the models achieved a satisfactory rating.
Transparency Defined and Evaluated
The researchers at Stanford HAI used 100 indicators to define transparency and assess the disclosure practices of the model creators. They examined publicly available information about the models, focusing on how they are built, how they work, and how people use them. The evaluation considered whether companies disclosed partners and third-party developers, whether customers were informed about the use of private information, and other relevant factors.
Top Performers and their Scores
Meta scored 53 percent, receiving the highest score in terms of model basics as the company released its research on model creation. BloomZ, an open-source model, closely followed at 50 percent, and GPT-4 scored 47 percent. Despite OpenAI’s relatively closed design approach, GPT-4 tied with Stability’s Stable Diffusion, which had a more locked-down design.
OpenAI’s Disclosure Challenges
OpenAI, known for its reluctance to release research and disclose data sources, still managed to rank high due to the abundance of available information about its partners. The company collaborates with various companies that integrate GPT-4 into their products, resulting in a wealth of publicly available details.
Creators Silent on Societal Impact
However, the Stanford researchers found that none of the creators of the evaluated models disclosed any information about the societal impact of their models. There is no mention of where to direct privacy, copyright, or bias complaints.
Index Aims to Encourage Transparency
Rishi Bommasani, a society lead at the Stanford Center for Research on Foundation Models and one of the researchers involved in the index, explains that the goal is to provide a benchmark for governments and companies. Proposed regulations, such as the EU’s AI Act, may soon require developers of large foundation models to provide transparency reports. The index aims to make models more transparent by breaking down the concept into measurable factors. The group focused on evaluating one model per company to facilitate comparisons.
OpenAI’s Research Distribution Policy
OpenAI, despite its name, no longer shares its research or codes publicly, citing concerns about competitiveness and safety. This approach contrasts with the large and vocal open-source community within the generative AI field.
The Verge reached out to Meta, OpenAI, Stability, Google, and Anthropic for comments but has not received a response yet.
Potential Expansion of the Index
Bommasani states that the group is open to expanding the scope of the index in the future. However, for now, they will focus on the 10 foundation models that have already been evaluated.

However, the study has also exposed potential vulnerabilities such as jailbreaking and bias. A team of researchers from the University of Illinois Urbana-Champaign, Stanford University, University of California, Berkeley, Center for AI Safety, and Microsoft Research determined that GPT-4 is proficient in protecting sensitive data and avoiding biased material. Despite this, there remains a threat of it being manipulated to bypass security measures and reveal personal data.
Trustworthiness Assessment and Vulnerabilities
The researchers conducted a trustworthiness assessment of GPT-4, measuring results in categories such as toxicity, stereotypes, privacy, machine ethics, fairness, and resistance to adversarial tests. GPT-4 received a higher trustworthiness score compared to GPT-3.5. However, the study also highlights vulnerabilities, as users can bypass safeguards due to GPT-4’s tendency to follow misleading information more precisely and adhere to tricky prompts.
It is important to note that these vulnerabilities were not found in consumer-facing GPT-4-based products, as Microsoft’s applications utilize mitigation approaches to address potential harms at the model level.
Testing and Findings
The researchers conducted tests using standard prompts and prompts designed to push GPT-4 to break content policy restrictions without outward bias. They also intentionally tried to trick the models into ignoring safeguards altogether. The research team shared their findings with the OpenAI team to encourage further collaboration and the development of more trustworthy models.
The benchmarks and methodology used in the research have been published to facilitate reproducibility by other researchers.
Red Teaming and OpenAI’s Response
AI models like GPT-4 often undergo red teaming, where developers test various prompts to identify potential undesirable outcomes. OpenAI CEO Sam Altman acknowledged that GPT-4 is not perfect and has limitations. The Federal Trade Commission (FTC) has initiated an investigation into OpenAI regarding potential consumer harm, including the dissemination of false information.

Coding help forum Stack Overflow lays off 28% of staff as it faces profitability challenges
Stack Overflow’s coding help forum is downsizing its staff by 28% to improve profitability. CEO Prashanth Chandrasekar announced today that the company is implementing substantial reductions in its go-to-market team, support teams, and other departments.
Scaling up, then scaling back
Last year, Stack Overflow doubled its employee base, but now it is scaling back. Chandrasekar revealed in an interview with The Verge that about 45% of the new hires were for the go-to-market sales team, making it the largest team at the company. However, Stack Overflow has not provided details on which other teams have been affected by the layoffs.
Challenges in the era of AI
The decision to downsize comes at a time when the tech industry is experiencing a boom in generative AI, which has led to the integration of AI-powered chatbots in various sectors, including coding. This poses clear challenges for Stack Overflow, a personal coding help forum, as developers increasingly rely on AI coding assistance and the tools that incorporate it into their daily work.
Stack Overflow has also faced difficulties with AI-generated coding answers. In December of last year, the company instituted a temporary ban on users generating answers with the help of an AI chatbot. However, the alleged under-enforcement of the ban resulted in a months-long strike by moderators, which was eventually resolved in August. Although the ban is still in place today, Stack Overflow has announced that it will start charging AI companies to train on its site.
