Radware, a publicly owned company founded in 1997 and headquartered in Israel, employs approximately 1470 people. The company's primary business is the development and provision of computer and network security solutions, specifically focusing on application delivery and cybersecurity for virtual, cloud, and software-defined data centers.
Radware's Security Research Centre (RSRC) discovered and disclosed a zero-click vulnerability, dubbed "ShadowLeak," in OpenAI's ChatGPT Deep Research agent on an undisclosed date. This vulnerability allowed attackers to extract user data from OpenAI servers without user interaction. On September 18, 2025, Radware publicly announced the discovery of this previously unknown zero-click vulnerability affecting the ChatGPT Deep Research agent. Radware's cybersecurity team described the process of discovering this flaw as a "rollercoaster" leading to a breakthrough revealing a method hackers could use to steal private data from Gmail accounts. The vulnerability, which has since been patched by OpenAI, was initially identified in February when OpenAI unveiled Deep Research, a tool allowing ChatGPT to access the internet and personal email inboxes.
