apparently intel has finally figured out why 13th and 14th gen CPU are failing. the issue is mainly caused by a faulty microcode algorithm, which causes the CPU requesting more voltage than it needs and results in oxidation issues within the chip itself.

CPU's that do not show any symptoms yet could be saved by a microcode update, but there is no real hope for those that already started to rust away

 

raise your paw if youre surprised that bad actors now distribute malware disguised as "crowdstrike fix / update"

love the quote at the end. there are far too many situations where windows is because "because!" where its just the wrong tool for the job. pos, web servers, trains to name a few i can think of...

 

So apparently Chrome ships with an extension that is invisible to the user, can not be disabled and allows any *.google.com page to get detailed information about CPU and memory usage.

It is apparently at least 10 years old, was originally developed to debug Hangouts and people do claim that it is also shipped in Brave and Edge.

Who knows what else might be hidden in there!

and i claim that i have a pig in my basement that plays celtic whistle and shits pure palladium every sunday

[–] tblFlip@pawb.social 3 points 5 months ago

ye, dont think ive seen anyone talk about that. sad

[–] tblFlip@pawb.social 10 points 5 months ago (1 children)

wonderful read. ive reached a point where i can do nothing but lean back, sip a drink and laugh while these companies race each other to destroy their platforms. might as well start betting on who does the next stupid decision...

 

Some people have apparently not only gone through the trouble of digging out the latest available version of Archie (old FTP indexer / search engine from the mid 80's / 90's before Google was a thing), but they even set up a fresh install and made a web interface available. Even better: The entire source code apparently also still exists.

breaking news: researchers discover that network protocols work as intended. mindlessly connecting to an untrusted network is still a bad idea.

to quote the article: "Do not use untrusted networks if you need absolute confidentiality of your traffic" or use HTTPS and a SOCKS5 proxy

 

perfectly level.

ok, after reading that article fully, it does sound a lot less concerning than the headline would like me to believe. it is early in the morning (almost 13:00) and this is a great chance to expose how little i know about all that, so i will:

They believed SSH traffic was immune [...].

classic. we always think that something is perfectly safe until it breaks. also, looking at the article, the issue with RSA has been known since 1996. there had to be a useful application for this. such as TLS. and now some SSH implementations.

Last year, researchers found that [...] they were still able to passively observe faulty signatures that allowed them to compromise the RSA keys of [...] Baidu.com

no idea how this adds any value in a discussion about SSH, but i chuckled.
now the article also get to some more interesting stats.

5.2 billion SSH records. of that 590k with invalid signatures and 4.9k revealed factorization for a total of 189 unique private keys.

now i would very much prefer that last number to be a solid zero, but out of 590k faults, only 4.9k were usable for the attack. everyone that thinks "oh thats nothing. im safe." is still a fool, but it could be far worse. especially since this only target RSA and leaves ed25519 (and others) untouched.

but it just gets even better:

The researchers traced the keys they compromised to devices that used custom, closed-source SSH implementations that didn’t implement the countermeasures found in OpenSSH and other widely used open source code libraries.

if i was drinking something reading this, i would have spat it out laughing. i am that kind of fun at parties. this also partially explains why there are "only" 590k invalid signatures in over 5.2 billion records total. and judging by how good some companies and organizations handle updates (assuming there will be updates from cisco, zyxel, hillstone and mocana), this will still be enough to be used in some attacks five years from now.

yep. and i wouldnt be surprised if that was intentional. how quickly they backed off on that one very much smells like a classic door in the face tactic. this whole WEI thing is far from being over

 

If you don't like flying drones, treat them as hardware CTF's instead!

 

Google's browser not only got new chrome, it now also uses keeps track of all websites you visit to generate a topic list for ads that is shared with websites directly. Nobody asked for that.

i honestly have so much trust into the whole music industry, and especially UMG, that id bet my best guillotine on this ending up to be absolutely detrimental to artists. if you have generative AI and can generate music for you, why even pay artists? sure sounds like the first step in that direction

 

a very interesting talk by Harald Welte about the complex mechanisms and architecture that keep eSIM working. prepare for a lot of acronyms

[–] tblFlip@pawb.social 3 points 1 year ago

im honestly not really surprised anymore. i fully expect to see a lot more of these types of bugs in the coming years

 

intel now joins the club with their take on GPU driver telemetry. they call it "Computing Improvement Program" and it can thankfully be disabled during a manual install, or in system settings after the installation is complete

[–] tblFlip@pawb.social 1 points 1 year ago

and im already dreaming of the day all of those (sometimes really hard to work with) pseudocode "implementations" that are scattered across wikipedia will be replaced with immediately runnable, CC-0 licensed code. itll probably take years, but i do like the idea
