hey your comment section is botted lol

[@rdahlinger4509]

Do you have any recommendations for someone who bought a new computer and the staples set it up in a bad way with admins and a fake windows defender that I can’t seem to figure out how to fix. I have Apache licenses and open sources and all of this stuff I have no idea how to fix. Thoughts?

[@homemedia4325]

This goes even deeper... you own a DNS name and then abandon it after several years... (perhaps an unforeseen event or your start-up fails)... Some 3rd party eventually purchased my old domain and used the way back machine to re-create the website... WARNING... think hard before abandoning a domain name!

[@tristunalekzander5608]

I don't get it, if the website is deployed from github, why would you ever delete your github account? You would have probably switched to another repo or just uploaded the files directly to your server before you delete your account while your website is still dependent on it. I also don't understand why this is only a vulnerability with subdomains.

[@lampagiul]

because you cannot create CNAME records for root domains

[@LuminousWhispers11]

You just have to delete the resource and not alter the dns records. Remember this was a demonstration.

[@777Yashobeamofchrist]

Guys, question. If you have control of the main domain and delete the entry for the subdomain that was took over, that would be the end off correct? Or is there a way to take full control of asub domain regardless of the main domain DNS records?

[@LuminousWhispers11]

@@777Yashobeamofchrist Yes, if you delete the dns records then no one can hijack the subdomain.

[@777Yashobeamofchrist]

@@LuminousWhispers11 thanks Rashad, do you know why some people claim bounty rewards to give subdomain back if it's as easy as deleting the record on root? That's what confuses me

[@n1027]

Thanks for your video. I learns a lot and useful to my job.

[@FunctionGermany]

i feel like this video was inspired by the "Avoiding DNS Pain" NDC talk that was uploaded 3 weeks ago. they cover this exact problem and also one solution (basically DNS as code like infrastructure as code).

[@NiceOwl84]

This happens all the time even for large companies including microsoft, amazon, walmart, etc that people use subdomains to send spam mail from the main domain from the actual company making hard to block spam mail because you can't just block the email address or the domain because you might actually want email from the actual company. Most email services don't allow blocking subdomains only email addresses themselves or primary domains. So people just make infinite amounts of sub domains for the primaries of an actual companies domains making it hard to block spam. At times it almost feels like the spammer have hacked the mail servers themselves and using it to spam and it's even funner when they are able to send spam mail out with no email address at all because the servers don't check to see is the account sending actually exist or even cares if the send mail is blank. It's even more fun when some emails services have auto avatar and names loading that get associated with the spammers email making it even look more like a real email. It's kind of hard for me to explain this lol.

[@M3laku]

Remember kids ... it's always DNS, always.

[@StrokeMahEgo]

The worst part of this...as an end user, there is really no way of knowing if this happened. You can get an SSL certificate for the redirected subdomain, which means HTTPS will work fine.

[@404-null]

Love your content.....keep doing great things!

[@MikeHarris1984]

For my company, our security requires any external facing sub domains can only be on 443, no 80 or re-directs like this shown. The owner has the attest to it and put new certs every 90 days and we monitor all external facing URL's. This is a serious open window that a lot of corporations do not even bother to worry about. But I'm glad I work with and lead one of the best IT security teams in my industry where we are constantly 5 steps further then what is required for our various regulations (PCI/ISO/SEC/FRB/etc...)

[@777Yashobeamofchrist]

Yes, they won't be able to use your domain name anymore. Unless your registered domain name is also controlled.

Is there a free hacking software for Windows? Like the one you use in Linux but then for Windows?

[@georgesporos2573]

Yes but if you use A record instead of CNAME aren't you more safe?

[@jrfrazier7598]

No you would have to use a CNAME in this case since you do not have IP access to Github's servers to redirect your site when requests are received for your subdomain. However, if you simply delete he CNAME in your DNS config, the crisis will be averted.

This week is hell and a bloodbath can happen but why we don't discuss the fact that Amazon also released their ANM27T in it? Always two sides of a coin

[@ward7576]

It just misses the point on why this can be so effective - if the original creator of the website links it IN his website, it's legit in the eyes of end-user and little to no precaution is taken.

[@thbadmin7751]

You would need to know that the GETHUB was available and a DNS record was pointing to it....highly unlikely to happen.

[@BradleyPitts666]

Did you watch the video?

[@zadekeys2194]

@NetworkChuck - You mention this is untraceable a few times. Off the top of my head, you could get insight via: 1) DNS Token canary (alert when hostname is requested). 2) URL Token canary (alert when URL is visited). Q - Any way to mitigate this with server side permissions or CloudFlare ? I used a PDF canary to track a document (as there was a suspected bad actor) and was able to then get public IP's and some geo data from the WAN they were connected to when opening the document. Proved the suspicion, and then the Executives got talking to the lawyers / police etc.

[@IND_SUBODH_GAMING]

Wow superb Boss 👍👍

[@BaileyMagikz]

i'm surprised GitHub makes usernames available after only 90 days it should be 365 days same with all socials or logins minimum

[@9SMTM6]

I don't know how that works precisely, but wouldn't they have to have valid SSL certificates? They could likely get one easy enough, but even for my small domain I get warnings of certificates are issued, so I'd notice if an certificate is issued without it being from me or my services. EDIT: Yup, going by you completing a DNS Challenge you had to get a certificate so that'd protect me. Also I don't point any of my subdomains to some route out of my control, so even not looking for certificates I should be fine as long as that's the case. And even if I do that, these will be the only kind of subdomains attack able with that exploit.

[@cxl520]

I think the way he showed it from here, you will be using GitHub's certificate? because he points your website to a GitHub website. If you want to know, you can follow his method to find out.
