  • Organizations – Teams integrating ChatGPT into workflows or encouraging employees to use AI tools.

What’s the risk?

Third-party plugins for ChatGPT are like apps on your phone—some are safe, and some aren’t. Recent research found that certain plugins had flaws that could have allowed hackers to:

  • Steal sensitive data.

Although these flaws have been fixed, they serve as a reminder to always be cautious when using third-party plugins.

  2. Lack of testing – Some plugins are used without thorough security checks.
  3. Inconsistent standards – Different third-party developers follow different practices, leaving gaps.

What’s the impact?

  • Data breaches – Loss of sensitive data and legal consequences.
  • Regulatory violations – Hefty fines for violating laws like GDPR.
  • Reputational damage – Customer trust takes a hit.
  • Business disruption – System outages reduce productivity.
