Another JavaScript nightmare has just been released. Cloudflare states that "Precursor is [...] built with privacy in mind [...]". The privacy guarantees? "The event listeners capture the minimum information needed to be a useful signal for detecting automation and abuse. For example, keyboard activity is captured as timing and rhythm, not as the actual keys pressed." Really?! https://blog.cloudflare.com/introducing-precursor/ #Privacy #Cloudflare #JavaScript #Precursor

@Hex@kolektiva.social I am surprised by how easy it is to bypass a VPN on iOS! "The SDK’s config ships a flag “use_netifs”: true. That flag triggers code in the SDK binary that constructs its NWConnection with a specific required interface: en0 (WiFi) or pdp_ip0 (cellular), rather than using the system default route. On iOS, this bypasses any configured VPN’s tun0 interface entirely. The peer tunnel does not cross a user-configured VPN, even when the rest of the app’s HTTPS traffic does." #VPN #iOS #privacy

@mcnado@mstdn.social The Ivermectin lobby has been on fire since the COVID-19 pandemic. Ivermectin for everything and everybody!

@dansup@mastodon.social Your decision to separate #Loops and #Pixelfed was a wise one!

@trison@social.tchncs.de That's true! Still, it would be very interesting to know how #Android stands in this issue. That's a major privacy breach.

RE: @signalapp@mastodon.world

Does Android keep a log of received notifications? If so, does it delete that log upon the deletion of an app?

@briankrebs@infosec.exchange If this whole AI-is-good-at-finding-bugs hype is true, any chance Microsoft and others would release patches for "unsupported" but still widely used software, e.g. Windows 10 or 7? @wdormann@infosec.exchange

@randahl@mastodon.social We have to find a way to block pathological narcissists from positions of power, both political ( #Trump, #Netanyahu ) and economical ( #Musk ).

@securedrop@social.freedom.press Great work! Has @protonprivacy@mastodon.social shown any interest in the project? It would be really nice to see them integrating WEBCAT into their suite. #WEBCAT #Security #Privacy #Web
