    During the first day of Pwn2Own Vancouver 2022, contestants won $800,000 after successfully exploiting 16 zero-day bugs to hack multiple products, including Microsoft’s Windows 11 operating system and the Teams communication platform.

    The first to fall was Microsoft Teams in the enterprise communications category after Hector Peralta exploited an improper configuration flaw.

    The STAR Labs team (Billy Jheng Bing-Jhong, Muhammad Alifa Ramdhan, and Nguyễn Hoàng Thạch) also demonstrated a zero-click exploit chain of 2 bugs (injection and arbitrary file write).

    Microsoft Teams was hacked a third time by Masato Kinugawa, who exploited a 3-bug chain of injection, misconfiguration, and sandbox escape.

    Each of them earned $150,000 for successfully demonstrating their Microsoft Teams zero-days.

    STAR Labs also earned an extra $40,000 after elevating privileges on a system running Windows 11 using a Use-After-Free weakness and an additional $40,000 by achieving privilege escalation on Oracle Virtualbox.

    Manfred Paul (@_manfp) also successfully demoed 2 bugs (prototype pollution and improper input validation) to hack Mozilla Firefox and an out-of-band write on Apple Safari to earn $150,000.

    Other highlights from the first day of Pwn2Own include Marcin Wiązowski, Team Orca of Sea Security, and Keith Yeo demonstrating more zero-days in Windows 11 and Ubuntu Desktop…

      So there is a bright future for you and this site to fill lots of pages #how_to apply and comply. And at the same time people are asked to trust the Microsoft Defendermeganism. Weird

      Thank you for this. It’s almost like Microsoft wants their code to be hacked. 😉

      It reminds me of the scene in The Fifth Element, in which Gary Oldman’s archcriminal industrialist character, Zorg, meets again with Ian Holm’s beneficent monk, Father Cornelius.

      Oldman intentionally breaks a drinking glass, which sets in motion automated machinery to clean it up. But during that scene Zorg also aspirates a cherry pit, nearly choking to death. Father Cornelius eventually slap’s Zorg’s back and saves him from death.
