I feel like that’s not even close to what the real number is, considering the impact it had.
If this figure is accurate, the massive impact was likely due to collateral damages. If this took down every server at an enterprise and left most of the workstations online, then that still means that those workstations were basically paperweights.
They have about 24,000 clients so that comes out to around 350 impacted machines per client which is reasonable. It only takes a few impacted machines for thousands of people to be impacted if they are important enough.
My bothers work uses VMs so if the server is down there’s probably 50k computers right there. But it’s only 1 affected computer.
As far as I know, none of the OSes used for virtualization hosts at scale by any of the major cloud infra players are Windows.
Not to mention: any company that uses any AWS or azure or GCP service is “using VMs” in one form or another (yes, I know I am hand waving away the difference between VMs and containers). It’s basically what they build all of their other services on.
I wonder if a large percentage of impact is internal facing systems.
And we won't know until Monday.
That's how supply chains work. A link in the chain is broken, the whole thing doesn't work. Also 10% of major companies being affected, is still giant. But you're here using online services, probably still buying bread probably got fuel, probably playing video games. It's huge in the media, and it saw massive affects but there's heaps of things that just weren't even touched that information spread on. Like TV news networks seemingly kept going enough to report on it non stop unaffected. Tbh though any good continuity and disaster recovery plan should handle this with impact but continuity.
The only companies I have seen with workable BCDR plans are banks, and that is because they handle money for rich people. It wouldn't surprise me if many core banking systems are hyper-legacy as well.
I honestly think that a majority of our infrastructure didn't collapse because of the lack of security controls and shitty patch management programs.
Sure. Compliance programs work for some aspects of business but since the advent of "the cloud", BCDR plans have been a paperwork drill.
(There are probably some awesome places out there with quadruple-redunant networks with the ability to outlast a nuclear winter. I personally haven't seen them though.)
CrowdStrike lives up to its name
Yknow I almost majored in IT/anything in that realm. Real glad I didn't right now. And most other times, but especially right now.
If you had majored in IT you would know that this Crowdstrike thing is an easy, though somewhat tedious, fix. There's honestly far more annoying problems that IT people have to content with.
How many systems in the world’s military went down, you know in war machines of Russia and Israel and Ukraine?
Those computers don't have auto update enabled
CrowdStrike’s channel file updates were pushed to computers regardless of any settings meant to prevent such automatic updates, Wardle noted.
Normally I would agree however this doesn’t appear to be a Microsoft update but a CrowdStrike update. Given that everyone is worried about ransomware etc.
Absolutely that. For networks that matter, patches are usually tested independently. While I wouldn't trust the average military command to do patch testing, any civilian/corporate contractors absolutely would, because money. (Microsoft is likely at the top of that stack...)
There are other conditions as well. EDR infrastructure, if it exists, would need to be isolated on a "Government cloud" which is a different beast completely. Plus, there are different levels of networks, some being air-gapped.
