Can someone in non marketing terms explain what the fuck CrowdStrike Falcon Sensor is? I literally never heard of this company or product before.
It's basically corporate anti-virus software. Intended to detect and prevent malware.
Apparently it's the next iteration of AI based antivirus where it uses smart algorithms to detect system behaviours and makes assessments on whether they're malicious or not

I know there is a lot of marketing fluff, but yes, it is an EDR. Which means instead of just checking file signatures against a database if known bad stuff, it actually examines what applications do and makes a sort of judgement on if it is acting maliciously or not. I use a similar product. Although the false positives can sometimes be baffling, it honestly can catch a legit program misbehaving.
On top of that, everything is logged. Every file, network connection, or registry key that every process on the computer touches is logged. That means when something happens, you can see the full and complete list of actions taken by the malicious system. Thus can actually be a drain on the computer, but modern systems handle it well enough.
What do you use? I’d be interested in that sort of thing
SentinelOne. They are more reseller/MSP friendly, but the product is very similar to CrowdStrike.
We also use S1 and while it does often flag false positives, that's a whole heck of a lot better than the alternative. Also I have not noticed it being very resource intensive.
It's overhead is more subtle than task manager can tell. Because of all its watching and monitoring, it slows down applications themselves. Task take longer. Sometime it is by a trivial amount, but I've been able to measure a notable difference in some task with and without S1, even if task manager says all is well.
obviously, A.I consider microsoft as a malicious software. Sometimes, A.I is very accurate 😁
Is it less expensive than ransomware though?
Yes
By a wide margin
Ransomware you have to pay $10,000 every few years. Crowdstrike you have to pay $1,000 per month. Same number of outages for both. /s
Add some extra zeroes to that ransomware figure...
Can you tell whether this update was delivered by Crowdstrike's own update delivery pipeline of via Window's update pipeline?
Absolutely nothing to do with windows pipelines or Microsoft
Okay, thanks. There was a parallel Microsoft outage, so I thought they were somehow linked.
Crowdstrike updates don't come through Windows Update.
It checks for malicious falcons in your system's level 4 aviary cache.
Ha ha! Well done!
It's software put on every machine so that the company can quickly isolate it if/when something bad happens (or it falls out of security compliance). To do this is requires a constant Internet connection, insanely high privileges on the machine and frequent updates to be appraised of risks.
That risk update went off the rails and into the next state.
