Pwn2Own 2022 – Windows 11, MS Teams and Firefox Pwned on Day 1

Other than Windows 11, Microsoft Teams and Mozilla Firefox, Oracle Virtualbox, Ubuntu Desktop, and Safari browser were also hacked on day one of PWN2OWN 2022 in Vancouver.

Pwn2Own is a hacking contest where white hate hackers come forward and compete against each other and earn thousands of dollars for detecting unknown vulnerabilities in popular software/OS. On the first day of the 15th edition of Pwn2Own, vulnerability researchers earned around $800,000.

According to the event organizer, Trend Micro’s Zero Day Initiative (ZDI), this was the highest single-day award amount ever won in this contest. All the ten hacking attempts were successful. The competition will conclude on Friday.

It is worth noting that this is the second edition of Pwn2Own in 2022. The first edition was held in Miami and focused mainly on ICS (industrial control systems). Participants earned $400,000 for successful exploits.

Microsoft Teams Exploits “Stole” the Show

Around $450,000 out of the total awarded sum of $800,000 was won by hackers who detected vulnerabilities in Microsoft Teams. Hackers exploited sixteen zero-day vulnerabilities against Windows 11, MS Teams, Firefox, Ubuntu, Oracle VirtualBox, and Safari. Hackers will again target Teams on the last day of Pwn2Own, on Friday.

For MS Teams, $150,000 were awarded for each of the 3 exploit chains leveraged by Masato Kinugawa, Hector Peralta (p3rr0), and the STAR Labs team comprising Billy Jheng Bing-Jhong, Muhammad Alifa Ramdhan, and Nguyễn Hoàng Thạch.

According to ZDI’s blog post, Peralta demonstrated an improper configuration. Kinugawa exploited a 3-bug chain, including a sandbox escape, a configuration, and an injection, while the STAR Labs team leveraged an arbitrary file write flaw and injection using a zero-click remote code execution exploit on Oracle VirtualBox.
