Interested in supporting me and gaining early access to the Web Security Academy videos when they're recorded? Consider buying my course: academy.ranakhalil.com/p/web-security-academy-video-series! ✨ ✨

[@MP-eq8fx]

Cant praise enough. May be its my shortcoming, but many paid courses couldnt explain me concepts which your videos did in a very simple way. I am learning now, and if I ever get a bounty, first thing will be to support you.

[@RanaKhalil101]

​@@MP-eq8fx No need to purchase my course. Glad you're liking the series!

[@MP-eq8fx]

Bought the course to support you. Hoping for more content soon

Your teaching style is the best. Really difficult to find teachers like you 😭. I'm having difficulties in XSS. Hope you will make videos on that too ❤️❤️

This is gotta be the best video on the Internet. I'm a fan now.

[@devinosborne3396]

7:55 and this is the best explanation i've heard yet. Well done. Very clear

[@govind22703]

For some reason, I really like listening u explain stuff. This reminds me of the science tv shows I used to watched as a kid :)

[@jub0bs]

44:45 "Of course, you need to use [SameSite] in addition to CSRF tokens and not as a defence on its own." This cannot be repeated enough 👏👏👏

[@thesecuritypoint]

Ohh mam, after so long time. Waiting the new topic after being master in sql😁

[@rajanrawal6396]

i don't even know how to put things into words the way how you explain, it's an amazing mam..we need such playlist more in the future..

[@baybars4392]

Hi Rana Khalil, my English knowledge is not very good, but if I ask that your videos are very instructive, can you add Turkish and English subtitle options to your video?

[@baybars4392]

???

[@MdParvej0x9]

awesome work 👍😀

[@itsksujan]

Hey @RanaKhalil, In stateless applications, how is the validation done? To check if the tokens provided are associated with the user's session and not an attacker's tokens sent with the user's session.

[@HakanGalip]

Thanks a lot clear to understand

[@wispawelwis38]

38:30 So where is the parameter csrf token (the one placed in POST body) stored if not in cookies? In local storage? Cant the attacked steal the csrf cookie?

[@paco7111]

It is part of form in as hidden field

[@wispawelwis38]

@@paco7111 but where is its value stored?

[@gnomoleproso47]

best video ever

[@rohitbhanot7809]

Just wondering why we need an and form to trigger the attack. Why cant just make the xhr request directly within the script tag ? It will give the same effect where when victim is tricked to load the page, the POST is automatically fired on load.

[@aqibmunshi6184]

Great video Rana. A quick question..why doesnt the browser attach the csrf token just as it attaches the cookie when the attacker sends a url of the site with email change parameter?. I mean how does the browser decide when to attach the csrf token and when not? I mean if an attacker sends me a link for email change and I have a cookie and token in the browser, why wont the browser not attach the csrf token at that point in time?

[@omarkhalid2966]

Waiting . . .

[@salahalgarhy3334]

Why is the subtitles closed on the video? Please look into this matter

[@forceboxed]

For stateless applications, shouldn't a single CSRF token (passed as hidden input field) be enough? Why do we need double submit defence?

[@محمدرضاجعفری-غ2ث]

Thanks

[@rahmanasadur8167]

Excellent

[@Hussain-we6tk]

Hi, I have a doubt as why Post Method will not include cookies?

[@allmusic1281]

rana I love your videos and the way you explain everything, is it possible that you can activate the subtitles in this video? my English is not very good, but with the subtitles I can understand your video perfectly, I hope it is possible and thank you very much for sharing your knowledge, it is of great value.

[@M0X0101]

waiting from Egypt

[@m0niruzzaman]

Excellent explain ♥️ Thank you!

[@nikhilbk3409]

Second question is Under Inadequate defense, instead of using the referrer header, if Origin header is used against Whitelist allowed origin, will it become another layer of security for CSRF attack OR is Origin header also can be spoofed?

[@abdelghafarmuhamed1013]

شكرا ليكي كتير

[@Phuongang-ti6ch]

Hello, I have a question What's the difference between buying a course and not buying it?

[@laxmantamong2364]

but how does the attacker know that the link has been clicked and email got changed?

Hi @RanaKhalil101, Your videos and explanation are really good. It made me understand the basics so much thanks a lot for this!! Reallly i mean it.

[@grayhat_9x]

You are amazing

[@nobackupkiwi]

I dont get how sql injections and csrf are related?

[@RanaKhalil101]

They're not.

[@nobackupkiwi]

@@RanaKhalil101 At min 16:50 you said to chain this two methods... I don't understand what you mean by that, could you please elaborate?

[@RanaKhalil101]

@@nobackupkiwi I was referring to chaining two vulnerabilities together assuming that the application is vulnerable to both. If an authenticated page is vulnerable to SQLi and the application does not use a csrf defense, then you can perform an SQLi attack within your CSRF attack in order to possibly gain code execution on the server. A more common example would be chaining a csrf attack with a command injection

[@nobackupkiwi]

@@RanaKhalil101 Clear as water. Thanks for the explanation. I hope there will be csrf+sqli cases in future labs.

[@the_shafei]

are there ones for XSS please ?

[@techtutorials7026]

Nice job

[@nikhilbk3409]

hello ma'am, I have doubt when the attacker send the email to victim with malicious link to click. In this case as you told in the Additional defense concept regarding SameSite attribute, since the victim clicked the link in the gmail, so if the SameSite=Strict then should CSRF attack will fail? because the request is initiated from the third part gmail. Is my undestanding is wrong?

[@gurvirsingh4190]

Great ❤️❤️

[@gfernandez2970]

I was wondering if it'd possible to add English subtitles, my sister is deaf, and I'm not pretty good at understanding English (we're from Spain), but both of us can read it. We're aware how good your material is, and it'd me amazing for us if that'd be possible. Thanks a lot in advance!

[@RanaKhalil101]

I wish it was under my control! KZbin automatically generates captions for my videos when I upload them. Unfortunately, for some reason, it didn't upload subtitles for this video :(
