In this first day, Ethical hackers earned $195,000 by exploiting the vulnerabilities that reside in the different products, In the second and final day of Pwn2Own Tokyo 2019, researchers made 6 attempts in various categories and earned $315,000 in total 2 days of this contest.

In the first entry of day 2, Team Fluoroacetate (Amat Cama and Richard Zhu) attempt to exploit the Samsung Galaxy S10 in the mobile category.

“Their rogue base station used a stack overflow to push their file onto the target handset. The successful demonstration earned them $50,000 and 5 Master of Pwn points and this is 3 rd time Samsung handset has been compromised via baseband”

In the next attempt, Fluoroacetate targeted the NETGEAR Nighthawk Smart WiFi Router (R6700) and successfully demonstrate the vulnerability.

In the next attempt, Pedro Ribeiro and Radek Domanski of team Flashback came back to target the WAN port of the TP-Link AC1750 Smart WiFi router.

They successfully exploit the bug using a stack overflow combined with a logic bug to gain code execution on the device that earned them $20,000 and one more points towards Master of Pwn.

In a total of 2 days contest, Team Flashback earned a total of $50,000 for four successful demonstrations.

Another Team from F-Secure Labs back to attack the WAN interface of the TP-Link AC1750 Smart WiFi router and they successfully demonstrate the combined command injection bug along with some insecure defaults to gain code execution on the device.

They also showed off their LED light skills by having the front of the router play “snake” for us. Style points asides, the successful demonstration earned them $20,000 and one Master of Pwn point.

In the next attempt, F-secure Team targeted the Xiaomi Mi9 handset via the NFC component.

” In order to exfiltrate a photo from the phone, they tapped it to their specially crafted NFC tag. That triggered a cross-site scripted (XSS) bug in the NFC component and sent a picture to a different phone they controlled.”

F-secure Team Final attempt earned them $30,000 and a total of $70,000 that take them to the second place of this contest.

Finally, Fluoroacetate holds the 18.5 points with $195,000 and retained their title of Master of Pwn.

Overall, we awarded more than $315,000 USD total over the two-day contest while purchasing 18 different bugs in the various products. ZDI said.
