Pwn2Own Hackers Just Broke Into Windows 11 and Teams in a Single Day

The hacking contest has seen some big wins for the hackers and some big losses for Microsoft.

Microsoft is taking a big stance on security with its latest software versions. As such, you would expect a bunch of hackers to have a hard time trying to crack it. Unfortunately, a hacking competition proved that wrong, as both Windows 11 and Teams were subjected to the power of some of the world’s best hackers in just one day.

Big results from the Pwn2Own contest

As reported on Zero Day Initiative, the Pwn2Own competition is currently underway. This contest pits hackers against each other as they try to crack software and show off their skills.

This may sound like some weird underground crime contest, but the truth is anything but. Pwn2Own is about ethical hacking. If a hacker finds a vulnerability, then they will privately report what they find to the developers so they can fix any flaws.

In return, hackers win themselves a well-deserved cash for their efforts. This symbiotic relationship is known as a bug bounty, and it’s a legitimate way for hackers to make some serious money with their skills.

The first day of Pwn2Own is over, and a look at the bounty table shows that Microsoft’s software hasn’t held up well against the onslaught. The event saw three successful attacks on Microsoft Teams and two attacks on Windows 11. Each successful hack was rewarded accordingly, with the lowest bounty being $40,000 and the largest being 150,000. dollars.

Microsoft isn’t the only victim in the contest; both Mozilla and Oracle also saw their software cracked for cash. But a lot of the results are coming from Teams and Windows 11, both of which pay very well to hackers who break in.


There are still two days left until Pwn2Own, so there are likely to be more successful attacks against Microsoft software. For now, however, the results of the day are more than enough to show how the Redmond giant’s software is performing.

A wake-up call for Microsoft

Microsoft has been huge on security so far. If you’ve tried to upgrade to Windows 11 on an older PC, you may be told that you can’t because your processor doesn’t support TPM 2.0. This requirement is to ensure that Windows 11 is as secure as possible.

However, the hackers managed to successfully capture potshots in both Windows 11 and Teams at the event, all on day one. And while Microsoft will get all the information they need to fix abused software, it shows that their programs are likely not as secure as one might initially think.

Back to the lab with Windows 11

With hackers taking a big win over Microsoft apps at Pwn2Win, it suggests that the company’s software may not be as secure as it should be. Hopefully Microsoft can publish fixes for these exploits before they fall into the wrong hands.
