Device Exploits Earn Hackers Over $1 Million at Pwn2Own Austin 2021

The Zero Day Initiative’s Pwn2Own Austin 2021 hacking contest has come to an end, with participants earning a total of more than $1 million for their router, printer, NAS device, smartphone, and smart speaker zero-day exploits.

Pwn2Own Austin has focused on hacking devices and ZDI described it as the largest Pwn2Own to date. White hat hackers earned $362,500 on the first day of the event, $415,000 on the second day, $238,750 on the third day, and $65,000? on the fourth day. Sixty-one bugs were disclosed at the contest — exploits typically chained multiple vulnerabilities — earning participants a total of $1,081,250.

The single highest bounties were paid out for Sonos One smart speaker exploits. Two teams earned $60,000 each for achieving arbitrary code execution and taking control of the device.

For the first time in Pwn2Own history, participants hacked printers — there were 11 successful printer hacks demonstrated at the event, earning researchers nearly $200,000.

There was only one successful and one partially successful attempt to hack the Samsung Galaxy S21. The successful attempt was rewarded with $50,000 and the partially successful attempt, which involved a known flaw, with $25,000.

In the router category, participants earned over $240,000 for hacking Cisco, Netgear and TP-Link routers. The highest reward, $30,000, was paid out to several teams for Cisco router exploits via the WAN interface.

In the NAS category, hackers received a total of $445,000 for demonstrating the exploitation of vulnerabilities in NAS devices from Western Digital. The highest single payout was $45,000 for an exploit that worked against the beta version of a device’s firmware.

Overall, the Synacktiv team earned the most money, nearly $200,000, followed by the Devcore team with $180,000.

It’s worth noting that in some cases the white hat hackers still earned tens of thousands of dollars for their exploits, even though they leveraged vulnerabilities that were previously disclosed to the affected vendor.

No one has attempted to hack televisions and external storage devices at this edition of Pwn2Own.

Vendors have been provided the details of the vulnerabilities exploited at the contest and they will be given 120 days to release patches.

While this has been the largest Pwn2Own in terms of the number of exploit attempts, the total amount of prize money paid out is slightly lower than in the case of the Pwn2Own that took place in April, where participants took home over $1.2 million for hacking Safari, Chrome, Edge, Windows 10, Ubuntu, Microsoft Teams, Zoom, Parallels, and Microsoft Exchange.
