Google discloses Windows zero-day 

Google believes the flaw is being actively exploited. According to Google’s Project Zero lead Ben Hawkes, the company expects the flaw to be patched on November 10th, Microsoft’s next Patch Tuesday. The exploit is a two stage attack, beginning with a zero-day Chrome vulnerability disclosed last week, that lets attackers run malicious code in Chrome. The Windows side allows the attackers to escape Chrome’s sandbox and run the code at the OS-level. The flaw impacts all Windows kernels from Windows 7 through the most current stable Windows 10 release.

How effective is Facebook fact-checking?

New research from Columbia’s Tow Center reviewed fact-check labels assigned to stories on Facebook from October 1st to 5th. Facebook’s ten US fact-checking partners debunked over seventy claims, many related to President Trump’s COVID-19 diagnosis and treatment. The researchers identified 1,100 posts across Facebook and Instagram and found less than 50% carried any fact-checking labels. The researchers found that Facebook’s automated AI review of content was often fooled by minor variations of memes.

Bridgefy gets end-to-end encryption

The offline messaging app Bridgefy has recently been used by protest groups, as its combination of Bluetooth and Wi-Fi allows for messages to be sent when the internet is blocked. Earlier this year, security researchers at Royal Holloway, University of London published a paper outlining a myriad of security vulnerabilities with the app, with messages not encrypted, and lacking basic sender verification, letting it be spoofed by third-parties. A new update to the app now adds end-to-end encryption. The update also prevents man-in-the-middle attacks, and one-to-one messages will no longer send user IDs in plain text.
