Major security issue found on several processors from the last few generations of AMD CPUs. Look at the details on zenbleed to see if you are at risk, this isn't another "requires physical access" or probing the back of your motherboard trick. This is a JavaScript based attack that can steal sensitive data like passwords straight out of your processor, and updates to consumer grade hardware aren't due until November or December.

In terms of mitigation, it looks like if you are logging in anywhere you should close any tabs that aren't for a website you trust implicitly isn't going to attack you. Take note, I have to enable scripts for almost every website I try to use, including seemingly every nostr related website. Nostr is the only social media I use, but I would not trust a single one of the great people on here to not be skimming passwords. This code could be anywhere and will royally fuck you up.
