I started doing some manual research into the security risks with different AI tools. But then I thought, why not get the AI to do it for me? So that’s what I did. Once again I am very impressed…

1. Data Privacy and Confidentiality

• ChatGPT: Users may inadvertently share sensitive information, potentially leading to data leaks. ChatGPT conversations may not always have the same enterprise-level data security controls, depending on deployment.
• Gemini: Google advises against sharing confidential information with Gemini, as conversations may be reviewed to improve quality, raising privacy concerns for sensitive data. (searchenginejournal.com)
• Apple Intelligence: Apple prioritizes on-device processing and privacy, with Private Cloud Compute to protect user data. However, the effectiveness depends on consistent use of these privacy features by users. (security.apple.com)
• Microsoft Copilot: Integrated within Microsoft 365, Copilot has enterprise-grade security and compliance features built-in, including support for GDPR, HIPAA, and other regulatory standards. However, the risk of users accidentally sharing confidential data through Copilot remains, especially if the model is trained on organization-specific data without strict data policies in place.

2. Phishing and Social Engineering

• ChatGPT: Can be exploited to craft convincing phishing emails or social engineering scripts by generating content that mimics corporate communication styles.
• Gemini: Google Gemini has been found to have vulnerabilities that could be exploited for phishing, potentially enabling attackers to take over chatbots or impersonate users. (securityweek.com)
• Apple Intelligence: While Apple Intelligence AI hasn’t been specifically linked to phishing exploits, any AI with language generation capabilities could potentially be leveraged for social engineering if misused.
• Microsoft Copilot: As it interacts with Microsoft 365 tools, Copilot has the potential to automate and personalize phishing messages within Microsoft’s suite, particularly within Outlook or Teams. Enhanced by organizational knowledge, phishing attacks crafted by Copilot could mimic familiar internal communication patterns, making them harder to detect.

3. Malicious Prompt Injections

• ChatGPT: Susceptible to prompt injection attacks that could manipulate the AI’s behavior to provide unintended or sensitive information.
• Gemini: Vulnerable to indirect prompt injection, which could enable phishing or chatbot takeovers. (securityweek.com)
• Apple Intelligence: Apple has measures to guard against vulnerabilities and offers rewards for identifying AI security flaws. However, the risk of prompt injection remains if used in complex workflows without safeguards.
• Microsoft Copilot: As Copilot becomes embedded across Microsoft 365 applications, prompt injections could potentially allow malicious users to exploit workflows or access sensitive data by manipulating Copilot’s responses. This is particularly concerning in applications where sensitive data is routinely processed, like Excel or SharePoint.

4. Data Exfiltration and Unauthorized Access

• ChatGPT: Without proper security configurations, there is a risk of data exfiltration if ChatGPT is misused or linked to sensitive applications.
• Gemini: Accused of unauthorized data scanning on Google Drive, Gemini has raised concerns over potential data exfiltration or access without user consent. (techradar.com)
• Apple Intelligence: Apple’s approach emphasizes on-device data handling to mitigate unauthorized data access, though secure implementation and user adherence are necessary to minimize risk.
• Microsoft Copilot: As an AI system integrated with Microsoft 365, Copilot has extensive data access, which could be exploited if permissions are misconfigured or if attackers find ways to bypass controls. Because Copilot can access files, emails, and other stored information, this could expose sensitive data if not closely monitored.

5. Compliance and Regulatory Risks

• ChatGPT: Compliance risks may arise if sensitive or regulated data is inputted, especially if stored outside organizational control, potentially violating GDPR, CCPA, or other regulations.
• Gemini: Google’s Gemini AI practices could pose regulatory challenges, particularly around user consent, data retention, and control over how user data is handled.
• Apple Intelligence: Apple’s privacy focus and on-device data processing align well with regulatory standards, but enterprises must ensure their specific use cases remain compliant with industry standards.
• Microsoft Copilot: Copilot aligns closely with Microsoft’s regulatory and compliance frameworks, making it a safer choice for organizations bound by strict regulations. However, organizations still need to ensure data governance policies are enforced to avoid regulatory risks related to AI-driven data processing.

Conclusion

While ChatGPT, Gemini, Apple Intelligence, and Microsoft Copilot each bring distinct features and security controls, core security risks are common across all platforms. These include data privacy, phishing, prompt injection vulnerabilities, data exfiltration risks, and compliance challenges. Microsoft Copilot offers the advantage of built-in enterprise security and compliance support, but also presents risks, especially around data handling, unauthorized access, and phishing automation.

For all platforms, implementing clear data-sharing policies, monitoring AI interactions, user training, and regular security audits will help organizations mitigate these risks effectively.
