During the Pwn2Own Ireland 2025 hacking competition, held in Cork from October 21 to 23, cybersecurity researchers from Team Z3 withdrew their planned demonstration of a zero-click remote code execution vulnerability in WhatsApp, opting instead to report it privately to Meta through a coordinated disclosure.
The withdrawal surprised attendees and fellow competitors, as the exploit could have earned Team Z3 the largest single payout in Pwn2Own history with a record-breaking $1 million bounty.
This substantial reward reflected the critical nature of zero-click vulnerabilities in an application used by three billion people worldwide.
