I don't mind having them put warnings when I try access a supposed "dangerous" link, but now they don't even present the option to advance anyway. This makes me worry about the future where you can't access something because someone of a higher power said No, not because it is dangerous, but because they don't want people to access.

Err, seems overly complicated when you can: Open "App & browser control" settings Choose "Reputation-based protection settings". Toggle off the switches for "Check apps and files" and "SmartScreen for Microsoft Edge".
@JoeHellethemayor 13 күн бұрын
The point of the issue wasn't that there is some other way to do it. It is that SmartScreen fails open when it can't call home, rather than falling back on something else to handle it.

It's a big given, but it's still useful info.

One possible thing MS and/or Google could do is that if it can't reach the destination of the safe browsing/smart screen DNS, it flashes an error on the screen warning about this nefarious behaviour of your local network, before it lets you to interact with any page. If you didn't do this, you might want to investigate.

I always had a weird feeling AVs blocking Bloodhound and even maybe mimikatz. I always thought about AVs that protect me from being compromised but in those cases it limits my usage of the machine. Yea, they can be used to compromise OTHER accounts and machines but it's weird that they limit me doing it even in a non AD joined machine. I want AVs to protect me from compromise and then not to moralize about what I want to do with my life!
@ThatBlueFalcon 12 күн бұрын
It's within a security tool's interest to block downloads of attacker tools, including Bloodhound and Mimikatz. If an attacker gained user priveleges on a host and Microsoft allowed users to freely download hacking tools from Github, that'd be a very convenient loophole to onboard tools. It's much better to download and use those tools using a sandbox environment without Defender/security features enabled, or even better just stick to a Kali distro where this wouldn't be an issue
@BryanLu0 12 күн бұрын
How does the AV differentiate between you using these tools and an adversary on your machine using them? It can't
@chrisjinks5414 13 күн бұрын
Thank you, i have just built a Defender hunting query to notify us if the hosts file is modified and or if a request to a Microsoft or google domains returns an IP that's not publically routable (as its then been hijacked or sinkholes), many thanks.

It's def a neat trick to stick in the tool belt and also as a mental exercise to possible defeat other security look up based measures. I think a good question here is why doesn't Microsoft and other big tech companies bypass DNS for these type of things?
@claudiafischering901 13 күн бұрын
Cool, but is it not more easier to turn it of the SmartScreen ? Maybe by registry or in edge itself? Or is it to avoid the message pops up you turn off SmartScreen ?

I'm curious about the CRDOWNLOAD file. While it is a temp file, I am guessing to check there is enough space to complete the download, in this instance, does it download the whole file? Or does it check with google/microsoft before completing the download and then flag it? If it does, can the extension be changed to give the original file?
@mollthecoder 12 күн бұрын
It's the browser temporarily saving info about the file, which can be used to start off where you left off if, for example, you lose internet for a moment. It can also be used for pausing/unpausing file downloads. That's what I know about CRDOWNLOAD, although I must admit I don't know a ton about it.
@demonagito666 3 күн бұрын
can you call the download in terminal to avoid the download via browser? or does it still flag it?

If you would know the licensing costs to Palo Alto you would not be asking this. It's pretty much among the lines if you need to ask how much it is you can't afford it. When I was in Uni that does co-operation with their development team we had discounted licensing to PA-220 and even price for that was eye watering.

i think a solution would be a notification explaining your dns settings may have been altered or something just in the case of malware but i guess av is kinda the limit here? hmmm i feel like the browser could totally help notify the user of tampering here tho

Thanks for the video! But is there a way to bypass the verification of phishing site that was made, for example, by security team of a company to educate the personnel? It is possible of course to distribute those changes to hosts file to all assets, but this can be dangerous, since no verification will be made for real malicious sites.

If the company makes the phishing site for personnel only then it really shouldn't end up on a SmartScreen or Safe Browsing list.

You won't see it up here as a KZfaq tutorial, because Cloudflare is way more serious. If you're able to bypass Cloudflare, then they would likely pay a good amount of money for you to tell them how. Or it might get sold to a government for even more money than Cloudflare would pay, in which case it would be even better kept under wraps.
