During the Pwn2Own Ireland 2025 hacking competition, cybersecurity researchers from Team Z3 opted to privately report a zero-click remote code execution vulnerability in WhatsApp to Meta, foregoing a potential $1 million public demonstration payout. This decision, aligned with ethical hacking standards, emphasizes user safety over public spectacle, as zero-click vulnerabilities pose significant risks due to their undetectable nature. Meta, the parent company of WhatsApp, has committed to addressing this critical flaw swiftly, leveraging a coordinated disclosure process that allows for timely patch development. The event overall was a success, with researchers identifying 73 unique zero-day vulnerabilities, underscoring the ongoing need for robust cybersecurity measures in protecting users against sophisticated threats.
