For almost two years, Microsoft officials botched a key Windows defense, an unexplained lapse that left customers open to a malware infection technique that has been especially effective in recent months.
Microsoft officials have steadfastly asserted that Windows Update will automatically add new software drivers to a blocklist designed to thwart a well-known trick in the malware infection playbook. The malware technique—known as BYOVD, short for "bring your own vulnerable driver"—makes it easy for an attacker with administrative control to bypass Windows kernel protections. Rather than writing an exploit from scratch, the attacker simply installs any one of dozens of third-party drivers with known vulnerabilities. Then the attacker exploits those vulnerabilities to gain instant access to some of the most fortified regions of Windows.
It turns out, however, that Windows was not properly downloading and applying updates to the driver blocklist, leaving users vulnerable to new BYOVD attacks.
OK that's definitely bad that they don't block it - but since you're an admin - why do you even care? the article says that the attacker is starting as a local admin.
Installers are typically local admins.
let me ask this another way.
Yes - it's bad that MS isn't blocking something they said they would.But does that make the situation any worse than it would really be if they did?
the attacker already has local admin - why would they need to install a driver that has vulnerabilities when they already have full local admin control - what advantage do they get they didn't already have?
Because they’re mostly things like automated installs. It’s not like someone is sitting at the keyboard as a bad actor. It’s an email with an attachment for a doc that when Sally opens it installs a valid signed driver that is vulnerable.

Exactly. Automated or confused users OR, don't forget, confused DEVELOPERS. It's not hard to get legit software, especially closed source, to think that MS signed drivers are safe (as that's the whole idea of the system is that everyone can trust them because MS is vouching for them) and trigger that they be installed, bypassing the expected security system.

I've seen that done by developers way to often.

In theory as a dev you are supposed to be able to rely on the IT team. If IT is okay with Windows, then you are kind of stuck.

Japanese fund secures 1 trillion yen to buy Toshiba
TOKYO (Kyodo) -- A Japanese investment fund has secured about 1 trillion yen ($6.8 billion) to buy out Toshiba Corp. and notified the embattled conglomerate that the amount was offered by a group of more than 10 Japanese companies, a source familiar with the matter said Monday.
But Japan Industrial Partners Inc. failed to meet Toshiba's request to submit a letter of loan commitments from major banks by Monday, the source said, leaving uncertain whether funds can be guaranteed for the takeover estimated at some 2.2 trillion yen in total.
Japan Industrial Partners, which leads a consortium that Toshiba designated the preferred bidder for the potential buyout, appears to be basing its total cost estimate on share price, as the figure equals the company's market capitalization, the source said.
In early October, Toshiba selected the consortium as the preferred bidder over Japan Investment Corp., a state-backed fund seeking to team up with Bain Capital for the buyout.
Toshiba has been struggling to recover from problems such as a window-dressing scandal and a massive loss in U.S. nuclear power business that surfaced in the 2010s.

No kidding. Too bad these are so big I'll never need one of my own. But hopefully the datacenters see these rolling in soon.

Some of the press releases have confirmed the big providers already have them in use, so yes, they're already being deployed.

GoTo (Formerly known as LastPass) has customer accounts breached...

@scottalanmiller Well GoTo owns Logmein and Lastpass so both products were breached one way or the other.

LogMeIn was the company, they rebranded to GoTo.
LastPass isn't owned by GoTo, but used to be. There shouldn't be any crossover. Breaching LastPass' stuff wouldn't imply that GoTo was breached too.

They had an issue on Friday that affected people with GEO blocking......After research we found some of the IP's trying to respond were based in India. Unblocking India from GEO fixed it. I imagine companies that are government or companies based in the UK would be able to sue the pants off them.

Nextcloud 26 is out. (I didn't even realize 25 had been released, lol).
Seems like a lot of glitzy stuff has been added.

Nice, I need to check out the latest.

This might just spark my interest to give Nextcloud a try again. Years ago, I gave up on self hosting my photos because it just wasn't "wife approved" enough for me. It was clunky and didn't "just work". So I chose to just go with auto backup with Amazon Prime Photos. That has been OK, but I do have to pay for it. My new idea to prove out is:
Have an app on iOS that automatically syncs all of our photos to a local server in my house. (I don't care what that is....nextcloud, something else that's better, whatever) Then nightly, sync that with Backblaze B2.
This seems like a simple concept, but years ago, it just wasn't user (wife) friendly. Maybe with the new release of nextcloud, this will be better?

FOr this I use Flickr. Way better than Amazon Photos.
