MagicShel ( @MagicShel@programming.dev ) 55•2 months agoIf this somehow works, good on Microsoft, but what the fuck are they doing on boot cycles 2-14? Can they be configured to do it in maybe 5? 3? Some computers have very long boot cycles.
vinniep ( @vinniep@beehaw.org ) English80•2 months agoThere’s nothing magical about the 15th reboot - Crowdstrike runs an update check during the boot process, and depending on your setup and network speeds, it can often take multiple reboots for that update to get picked up and applied. If it fails to apply the update before the boot cycle hits the point that crashes, you just have to try again.
One thing that can help, if anyone reads this and is having this problem, is to hard wire the machine to the network. Wifi is enabled later in the startup sequence which leaves little (or no) time for the update to get picked up an applied before the boot crashes. The wired network stack starts up much earlier in the cycle and will maximize the odds of the fix getting applied in time.
MagicShel ( @MagicShel@programming.dev ) 34•2 months agoThat makes sense with how the article said “up to 15 times” which does sort of indicate it’s not a counter or strictly controllable process. Thank you!
EtzBetz ( @EtzBetz@feddit.de ) 10•2 months agoI was thinking (from reading the headline) that if one specific component fails 15 times during boot or so, it will just automatically get disabled by the system, so that you don’t run into an unavoidable boot loop.
But this makes sense as well, if they did write “up to” in the article (as others have stated).
Even though I find the confidence weird. Imagine you have some weird dial-up or satellite internet solution for your system, which just needs time to connect, and then maybe also just provide a few bytes/kilobytes per second. This must be rare, but I’m 100% confident that there exists a system like this :DEdit: okay, I should read first. The 15 times thing is said for azure machines.
darkpanda ( @darkpanda@lemmy.ca ) 8•2 months agomacOS has something to this effect where if it detects too many kernel panics in a row on boot it will disable all kernel extensions on the next reboot and it pops up a message explaining this. I’ve had this happen to me when my GPU was slowly dying. It eventually did bite the dust on me, but it did let me get into the system a few times to get what I needed before it was kaput.
EtzBetz ( @EtzBetz@feddit.de ) 2•2 months agoInteresting to know :)

Gormadt ( @Gormadt@lemmy.blahaj.zone ) 42•2 months agoThe IT guy quits and it’s no longer their problem to fix
MagicShel ( @MagicShel@programming.dev ) 9•2 months agoProbably triggers some auto-rollback mechanism I’d guess, to help escape boot loops? I’m just speculating.
NeatNit ( @NeatNit@discuss.tchncs.de ) 30•2 months agoWelp, Ars Technica has another theory:
Microsoft’s Azure status page outlines several fixes. The first and easiest is simply to try to reboot affected machines over and over, which gives affected machines multiple chances to try to grab CrowdStrike’s non-broken update before the bad driver can cause the BSOD. Microsoft says that some of its customers have had to reboot their systems as many as 15 times to pull down the update.
MagicShel ( @MagicShel@programming.dev ) 8•2 months agoYep. That makes more sense. Thanks!
NeatNit ( @NeatNit@discuss.tchncs.de ) 8•2 months agoThat’s some high quality speculation

that was your first problem. if it was designed by techbros, always assume it’s Straight.

30p87 ( @30p87@feddit.de ) 23•2 months agoWell in the time until Windows rebooted 15 times Windows 12 will be out.
the 12 is for how many times you need to reboot it when you first get it
zephorah ( @zephorah@lemm.ee ) 11•2 months agoWe did get 7 computers back by 1am last night just by constantly rebooting.
That said, 40 out of 47 never came back. So clearly something more is needed.
Chahk ( @chahk@beehaw.org ) 8•2 months agoHave you tried 15 more reboots?
gwindli ( @gwindli@lemy.lol ) 8•2 months agothere’s an easy fix. it could be done with a single boot attempt if M$ hadnt made it so needlessly difficult to enter safe mode
Norgur ( @Norgur@fedia.io ) 7•2 months agoMany of the machines in question will have safe mode walled off for security reasons anyway.
gwindli ( @gwindli@lemy.lol ) 1•2 months agofair enough. i can see that disabling safe mode would be a decent security measure. but by the time that kind of exploit is used, you’ve already got bad actors inside your network and there are much easier methods available to pivot to other devices and accounts.
NaN ( @Bitrot@lemmy.sdf.org ) English2•2 months agoLaptops are often taken outside the network.
Scary le Poo ( @Scary_le_Poo@beehaw.org ) 2•2 months agoWell then obviously you could opt to restrict safe mode on laptops only, or laptops and desktops allowing you to get your server infrastructure up quickly so at least the back end is running properly.
Ffs.
jarfil ( @jarfil@beehaw.org ) 1•1 month agoServers with KVM access, could have it compromised, letting bad actors enter safe mode.
Scary le Poo ( @Scary_le_Poo@beehaw.org ) 1•1 month agoIf your RMM gets compromised then you have much larger issues.
jarfil ( @jarfil@beehaw.org ) 1•1 month agoDoesn’t need to be fully compromised, but it isn’t unusual for the access credentials to some portion, to be stored on an easier to compromise system. Disabling safe mode on a server, prevents stuff like a single compromised laptop, from becoming a full server compromise.

Midnitte ( @Midnitte@beehaw.org ) English24•2 months agoActually it’s due to whether your company uses CrowdStrike or not.
Supposedly, one of the fixes (aside from rebooting and hoping it grabs the update fire) is to delete a single file in the CrowdStrike directory after booting into safe mode.
nutlink ( @nutlink@beehaw.org ) English6•2 months agoI just spent the morning doing this with my help desk team, although we just do it via command prompt at the recovery screen. We’ve had a 100% success rate so far at 93 devices and counting. I’m glad our organization practices read only Friday, at least.
EtzBetz ( @EtzBetz@feddit.de ) 3•2 months agoTbh, I would then also not update anything on Thursdays (which does maybe do overnight procedures) since it may be breaking over night then, leaving you just little time to fix before the weekend :D
This kinda can be extended up until Monday, I know, but, at least in Germany, on Fridays people go home way sooner than other days.
Saik0 ( @Saik0Shinigami@lemmy.saik0.com ) English2•2 months agoYes, but Azure platform itself was using it. So many of those systems were down overnight (and there’s probably still stragglers). The guy you responded to specifically called out Azure-based services.
Midnitte ( @Midnitte@beehaw.org ) English4•2 months agoSure, but the OP of the thread didn’t.

So it isn’t whether you’re using Azure, it’s whether you’re using CrowdStrike (Azure related or not)
Saik0 ( @Saik0Shinigami@lemmy.saik0.com ) English2•2 months agoSo it isn’t whether you’re using Azure, it’s whether you’re using CrowdStrike (Azure related or not)
No. Azure platform is using Crowdstrike on their hypervisors. So simply using Azure could be sufficient to hurt you in this case even if your Azure host isn’t using Crowdstrike itself. But yes, otherwise it’s a mix of Windows+Crowdstrike.
Kissaki ( @Kissaki@beehaw.org ) English4•2 months agoCan you source your claim, that Azure hypervisor uses CrowdStrike? Because a Microsoft spokesperson told Ars that that issue was unrelated to the CrowdStrike update.
[…] cited as “a backend cluster management workflow [that] deployed a configuration change causing backend access to be blocked between a subset of Azure Storage clusters and compute resources in the Central US region.”
A spokesperson for Microsoft told Ars in a statement Friday that the CrowdStrike update was not related to its July 18 Azure outage. “That issue has fully recovered,” the statement read.
Kissaki ( @Kissaki@beehaw.org ) English3•2 months agoMicrosoft services were, in a seemingly terrible coincidence, also down overnight Thursday into Friday. […]

They were not “using it”. And there’s no “stragglers still”.
