Security researchers collected $792,750 in cash after exploiting 56 unique zero-day vulnerabilities during the second day of the Pwn2Own Ireland 2025 hacking competition.

Today’s highlight was Ken Gannon of Mobile Hacking Lab and Dimitrios Valsamaras of Summoning Team hacking the Samsung Galaxy S25 with a chain of five security flaws, earning $50,000 and 5 Master of Pwn points.

Also, while PHP Hooligans needed only a single second to hack the QNAP TS-453E NAS device, the vulnerability they exploited had already been used in the contest.

Chumy Tsai of CyCraft Technology, Le Trong Phuc and Cao Ngoc Quy of Verichains Cyber Force, and Mehdi & Matthieu of Synacktiv Team were also awarded $20,000 for breaking into the QNAP TS-453E, Synology DS925+, and the Phillips Hue Bridge.

The contestants also exploited zero-day bugs in the Canon imageCLASS MF654Cdw printer, Home Automation Green, Synology CC400W camera, Synology DS925+ NAS, Amazon Smart plug, and Lexmark CX532adwe printer.
