Hackers Breach OpenAI Codex and Smart Devices, Claiming 32 Zero-Days at Pwn2Own Ireland

Security researchers uncovered 32 zero-day vulnerabilities on the first day of the Pwn2Own Ireland 2026 competition. Participants claimed over $368,000 in prize money by targeting smartphones, smart home hardware, printers, and AI tools including OpenAI Codex and LiteLLM. According to Google, total vulnerability disclosures doubled from 5,045 in January 2026 to 10,740 in August, as AI-enabled offensive tools increasingly accelerate exploit research. While 50% of AI-discovered vulnerabilities result in remote code execution, separate research indicates only 1% of these flaws are currently being actively exploited in the wild. Affected vendors are given a standard 90-day window to release security patches before the Zero Day Initiative publicly discloses the flaws.
