Pwn2Own Tokyo 2019 has come to an end and on the second day of the hacking contest bug bounty hunters have earned a total of $120,000 for demonstrating exploits against Samsung Galaxy S10 and Xiaomi Mi9 phones and TP-Link AC1750 routers.
Of the seven hacking attempts scheduled for day two, four were a complete success. Amat Cama and Richard Zhu of the Fluoroacetate team earned $50,000 for pushing an arbitrary file onto a Samsung Galaxy S10 after the device connected to their rogue base station. At the end of the day, they made a second attempt to hack the Galaxy S10, via its web browser, but they exploited a vulnerability that had already been used by a previous contestant.
Zhu and Cama have earned a total of $195,000 over the two days of Pwn2Own and they have been declared the winner for the third year in a row.
Pedro Ribeiro and Radek Domanski of Team Flashback earned $20,000 for hacking a TP-Link AC1750 router through its WAN interface. The same router was also hacked by the F-Secure Labs team, which also earned $20,000. Both teams managed to achieve arbitrary code execution on the device.
The F-Secure team also received $30,000 for an exploit targeting the Xiaomi Mi9 phone. They exploited a cross-site scripting (XSS) vulnerability in the device’s NFC component to exfiltrate data simply by touching a specially made NFC tag.
In total, over two days, Pwn2Own contestants received $315,000 for disclosing 18 different vulnerabilities, all of which have been reported to the impacted vendors. They have been given 90 days to patch the security flaws.
