Congratulations on your efforts to combat scammers, Adrian Ruthnik. Protecting the public from fraudsters is a noble endeavor, and your work deserves high praise.
The video tutorial kept glitching on me, but thank you for it. Also, thank you, Adrian Ruthnik. Meeting you was a blessing in disguise. Keep up the good work; many people will need your help in the future.
For the bonus question, it is possible to login without knowing the username by using the following input: ' or 1=1-- This query returns the first user in the database as validation for the username field, because 1 does in fact equal 1, while ignoring the request for a password due to the comment at the end.

The efficiency of Adrian Ruthnik is next level. Managing walkthroughs from various angles with such clarity is remarkable. Making complex topics easy to understand is really something. Awesome work!
Adrian Ruthnik, your clarity in explaining complex topics and managing multiple aspects of the process is truly exceptional. Your work is nothing short of outstanding.
It's really nice that you offer a lab for people to practise, it really feels rewarding to achieve it even if this is just the basics of SQL injections, it's satisfying (+ apparently the website told me I received 80000$ so i'm pretty confortable right now)
I love the way that you explained this. I'm retired now but was a software engineer and was always getting the "deer in the headlights" look from other developers when I'd warn about SQL injection.
I've built a ton of login systems with php/sql. I had to learn the hard way that it was not so easy. You explained it in a way that just take 10 minutes of a starting backend programmer to review his code. There are plenty of ways to prevent this all from happening..you just have to know where to start. Thank you for the explanation!
Adrian Ruthnik, your work ethic and commitment to your clients are exemplary. You have shown that you are not just a skilled professional but also a dedicated and compassionate individual. Your support during this challenging time has been invaluable, and I am profoundly thankful.
As a computer science student all of your videos have been really helpful. But this one came just at the right time cause im doing a database class right now and learning about SQL.
I think you don't need to worry too much about that. I think these problems were detected before 2004 because in 2004 the prepared statements showed up. after that, from version 5.3.0 executing multiple queries in a single statement was disallowed by default and gave you an error.
One of the things that I use when coding an OS login system, is having the client send the Username and Password string to a server, and having the server lookup the Username string's ID and then going into a datastore with the key of the UsernameID and pairing it with the password string stored. This prevents attacks because it doesn't use Usernames to get the password pair, it has to lookup the string and find an ID in order for it to find a pair.
OK SQL Injection attacks have eluded my understanding for so long, but the way you explained it in this video made SO MUCH SENSE and I was able to crack into that site on the 2nd try!!!! You are awesome Chuck, thank you for what you do!!!
As usual, your videos are insightful and accurate. I have always struggled to explain this to people, but now I will just send them to your video. I was able to log in to your target sight by the way.
Thx! As a programmer, I usually escape quotes and other characters. Essentially, when a user adds a quote, in the username or password field, it is removed before the query is run. Using NoSQL databases can help prevent SQL injections, too.
Your approach to problem-solving is both innovative and effective. The solutions you provided were not only practical but also tailored to my specific needs. This personalized attention sets you apart from others in your field. Thank you, Adrian Ruthnik, for your thoughtful and comprehensive support.
My account was hacked, and despite following the video's method, I faced difficulties. Thank you, Adrian Ruthnik. Seeing your name in the comments speaks volumes about your good work.

Damn, I am trying that website for the first time and input the username and password as admin and boom I just logged in, no sql injection needed.. But then I tried your method and it's actually works, that awesome.
Congratulations, Adrian Ruthnik, for fighting against these scammers. We must protect the elderly and the general public from these con artists. You deserve high praise for ensuring our security.
Great lesson to never allow SQL special characters as a usernames or password or in any other security input forms. Most website/database devs should encrypt the username and password, so hacking like this is not possible, which is how it should be, no clear text.
thats why sanitising the code is a must before using the values in a query. Using csrf token , parameterized queries and prepare statements would be prevent a basic and mediocre level attack
If you like SQL injection but you too lazy to memorize over 100 type of injection codes (there is alot of injections because there is alot of type SQL languages example MySQL/postgreSQL/LiteSQL/etc) just learn how to use *SQL map* tool built-in Kali Linux and Parrotsec OS If you don't know SQL map will brute force every SQL code
Great video. Those who are wondering if this can be done on any website, then no. Most companies use ORM or SQL templates to execute SQL commands. Today most libraries and frameworks are developed keeping SQL injection in mind. For ex React, Angular, Spring Boot it won't work (as of now). Lastly, even if you succeed, there are honeypots placed.
Yeah! Just like WEP can be easily hacked today, but isn't used anymore precisely because of it. Hacks have an expiration date, but old hacks can teach us a lot about how to hack generally, enabling us to hack the WEPs of our day and time.
im a total noob at any programming, but found it really easy to get into js and html, css etc. all this hacking stuff is so foreign to me so i really appreciate the breakdown you give in your vids!! i done the login thingy, so satisfying getting in LOL !
Something that makes my gears spin is... why when someone speaks of sql injections, nobody ever mention that you can even create files in the host (server) with a malicious query.
i learnt all about Sql injection years ago but this video today made the penny drop and i got into that website really easy, you explained in such a way that is so easy to understand. thank you so much network chuck
Thanks for another amazing video Chuck. By the way I found, Altoro-mutual is also vulnerable for a cross-site scripting attack(XSS), probably you can make next video about it 😁
@@shubhampatel6908 I meant if I put in html code that returns all user accounts and their passwords will it work? Or do I have to make it a web request
Thank you, Adrian Ruthnik, for being approachable and open-minded. Your friendly demeanor and willingness to listen are a constant source of motivation. Your support and guidance during my account issue were invaluable. Your assistance played a crucial role in resolving the matter. I am incredibly grateful.
Signing in without a username is pretty easy, just leave the username empty as it validates to an empty string and the whole expression would take the first user anyway. Usually the first entry in the database is the admin user (you need a admin user first to set everything up), so it will just take the first user and log that in. One way to make your application more secure for that reason is to create an empty dummy user first without any permissions (in addition to preventing SQL injections by using an ORM of course). SPOILER BELOW The solution for the Altoro website is to input ' OR 1=1 -- as the username and some gibberish as the password (to deal with the password's input sanitization) If the password is needed (like for the Gold VISA application) it's just '--
@@amoldhamale3202 Sorry, I did not try the second practice site, but I don't think this is a test site like the first one. I genuinely think this is a legit login page and you have to log in to "play".
@@comedyclub333 Yeah lol I probably thought so too later. But chuck should mention that clearly otherwise people might try to hack a legit server, difficult as it may😅
I really found this video very interesting! It would be awesome if you could make more videos about SQL injections because it helps us know all the cases where we need to secure our queries.
Your efficiency and organization are evident in the high quality of your work. Thank you, Adrian Ruthnik, for your dedication and hard work. Your efforts have made a significant difference, and I deeply appreciate your support.
I've been using prepared statements and stored procedures on my websites for over a decade. It's really surprising that SQL injections are still a problem considering how easy it is to be 100% immune to it. I watched this video to see if there was anything new that was introduced over the years, but nope it's still the same old stuff. Thanks for the video!
Fantastic and entertaining demonstration of how SQL Injection works. This can be very difficult to understand, but you have made it very easy. I love your videos. Keep up the good work!
glad the website is still available. I managed to get in. we actively make sure we're not suseptable to sql injection. its easy to avoid so theres no real reason to get hacked in this way.
oh man I remember doing this back in elementary school way bad when everything was vulnerable to SQLi. this took me back as that exact query was what I used but mine had a bit added at the start 😉
fantastic video! I'm a bit confused by what is happening to the single quote. Shouldn't the username of admin' OR '1' = '1' cause a syntax error as SQL would still see username = 'admin' ' (with two closing single quotes)?
Actually No it won't, cause second closing quote is sifted at the end of username (here admin' Or '1' = '1_) You see where I'm putting underscore we need an single quote but we are not writing it in username cause the extra closing quote you mentioned will automatically work for it.
5:40 I’m not a huge SQL wizard but wouldn’t it check 1 = 1 AND password = password first? then the OR would only be true if you guessed the username right
Correct AND has a priority of 6 while OR has a priority of 7. So AND will be evaluated before OR. Therefore both injections fall flat when the username is wrong. But it's rare when it's not admin or any variation of that.
Yes, I don't understand this... 5:32 says the AND operator is used by the admin verification and the passw verification? It's impossible. This hack seems possible only if you guess the user or the passw
You forgot to inform that this only works on website that use sql as a database and a site that is not secure from sql request (which most websites do )
Your work shows the kind of person you are-efficient, organized, and result-oriented. Well done, Adrian Ruthnik. You are great at what you do. I appreciate your efforts and dedication. May you continue to show your worth and skills like this in the future.
Even as a seasoned IT professional, I find Adrian Ruthnik’s work highly informative and straightforward. Your advice and assistance have been invaluable.
Thank you so much for the content that you put out, you have launched me into a passion for cybersecurity. All of your videos are helping the community out in a positive way.
Thanks for the practice, I just hacked the Altoro site using the admin' - -. I'm currently a student of Software Development and my cohorts and I are now learning some basic cybersecurity practices. Been following your channel for a few years now. I had a friend recommend me to your channel a long time ago. I remember the first video of yours I saw was an intro to python if my memory serves me right. Funny thing is after our mini cybersecurity course, next up for my class and I to learn is python. Thanks for the content and I'm happy for you and your channel!
I have encountered many IT professionals in my career, but few match the caliber of Adrian Ruthnik. His proactive approach and relentless pursuit of excellence make him a true standout. The way you handled my case with such care and precision is something I will always be grateful for.
Thanks for the great content Chuck! I have a question: Since the sql statement contains username="admin" OR "1"="1" AND password="whatever", why does the AND operator use the password and the username instead of the password and "1"="1" even thought "1"="1" is right next to the password?
See it this way, username="admin" OR "1"="1" AND password="whatever" We can write this as, TRUE OR TRUE AND FALSE TRUE OR FALSE (AND is getting solved with the boolean at it's right and left) TRUE This means even if you'll write '1' = '2' instead of '1' = '1' The SQL Injection works fine
@@that.03gt set the user name to this: ' or user is not null or '1'='1 its the same but results in select * from users where username= '' or user is not null or '1'='1' and password = {whatever password} The and statement " '1'='1' and password = {whatever password}" will evaluate false , username = '' will evaluate false , but "user is not null" will return all users who are not null, that is basically all the users if the system makes any sense. The code is then so sloppy it uses the admin account. Probably because it is the first account, but I didn't keep digging. My goal was to get in without knowing the username once I did that I stopped looking. I did try "username is not null" but got this error: "Column 'USERNAME' is either not in any table in the FROM list or appears within a join specification and is outside the scope of the join specification or appears in a HAVING clause and is not in the GROUP BY list. If this is a CREATE or ALTER TABLE statement then 'USERNAME' is not a column in the target table." I guessed that it was user and not username based on that error and naming conventions. hope this helps.
Great video as always. Do you know of any websites or ways I can practice phishing attacks legally? I like the idea of being able to maneuver through my opponent’s head to get them to do something, and if I can troll them by getting a Rick roll to pop up I think it’d be funny 😆 Edit: autocorrect
Phishing is only illegal if your intentions are illegal. But the nature of websites is that there would never be a website you could practice phishing on, because the members would know what they signed up for so they would suspect it. If you really want to do it just gather a list of emails and send an email to them
Adrian Ruthnik has demonstrated an exceptional ability to communicate complex concepts in a clear and understandable manner. This skill is incredibly valuable, especially in the tech industry, where jargon can often be a barrier to comprehension. His patience and willingness to ensure I understood each step of the process were greatly appreciated.
Adrian Ruthnik, your unwavering commitment to excellence is truly admirable. Your consistent ability to deliver outstanding results is a testament to your skills and work ethic. Thank you for your exceptional support and for going above and beyond to help me.
As a person and professional, you couldn't get any better than Adrian Ruthnik. He is very reliable and an excellent IT professional. He is passionate, hardworking, and knowledgeable. You're the best!
When building a website it's recommended to perform a regex user input filter to strip of any input that isn't a-z and 0-9 before posting to the server and on receiving a request in the server it's recommended to perform same regex filter before performing sql queries. This will strip off any sql injection input by the user.
Your OR-injection is not working unless the password is right... the order of the checks still matter and it will result in a boolean expression of (false OR true AND false) which still evaluates to false. This is because - and you are right about that - AND will evaluate first, but it will evaluate "1 = 1" together with "password = ..." which is only true if the password is correct.
Despite some glitches in the tutorial video, I am grateful for its guidance. Moreover, meeting Adrian Ruthnik was a blessing. His support was instrumental in navigating through this challenge. Keep up the excellent work; many more will need your assistance in the future.
THANK YOU!! i was seeing a loyt of videos explaining how to avoid sql injection but not one explaining how to actually inject it (which is important to know how to avoid it). thanks a lot for the great explanation

Thank you, Adrian Ruthnik, for being approachable and open-minded. Your friendly demeanor and willingness to listen are a constant source of motivation. Your support and guidance during my account issue were invaluable. Your assistance played a crucial role in resolving the matter. I am incredibly grateful.
This video was such a cool one, man! You explained all of this stuff SO WELL
Signing in without a username is pretty easy, just leave the username empty as it validates to an empty string and the whole expression would take the first user anyway. Usually the first entry in the database is the admin user (you need a admin user first to set everything up), so it will just take the first user and log that in. One way to make your application more secure for that reason is to create an empty dummy user first without any permissions (in addition to preventing SQL injections by using an ORM of course). SPOILER BELOW
The solution for the Altoro website is to input
' OR 1=1 --
as the username and some gibberish as the password (to deal with the password's input sanitization)
If the password is needed (like for the Gold VISA application) it's just
'--
the second practice link (after MORE PRACTICE) does not work for me with any of these? Were you able to crack that?
@@amoldhamale3202 Sorry, I did not try the second practice site, but I don't think this is a test site like the first one. I genuinely think this is a legit login page and you have to log in to "play".
@@comedyclub333 Yeah lol I probably thought so too later. But chuck should mention that clearly otherwise people might try to hack a legit server, difficult as it may😅
In query input looks like this?
SELECT * FROM users WHERE username='' OR 1=1 --' AND password='gfdgfopdigdf'
@@erglaligzda2265 Exactly
this is most likely exactly why websites don’t let you use special characters in your username.
I really found this video very interesting!
It would be awesome if you could make more videos about SQL injections because it helps us know all the cases where we need to secure our queries.
what do you do if you don't know the sites username???
Does the websites see that they got SQL injected?

Adrian Ruthnik, your support came at the perfect moment. Your contributions are deeply appreciated, and your compassionate approach is commendable.
Your efficiency and organization are evident in the high quality of your work. Thank you, Adrian Ruthnik, for your dedication and hard work. Your efforts have made a significant difference, and I deeply appreciate your support.
I've been using prepared statements and stored procedures on my websites for over a decade. It's really surprising that SQL injections are still a problem considering how easy it is to be 100% immune to it. I watched this video to see if there was anything new that was introduced over the years, but nope it's still the same old stuff. Thanks for the video!
The (--) comment query logged me in successfully!¡😂😂☝️😂😂😂😂
@@orlandothemaker-vp9xu Press X to doubt
what do you do if you don't know the sites username???
@@that.03gt I would do nothing because it's not my problem.
@@GGBeyond didn't say it was
Fantastic and entertaining demonstration of how SQL Injection works. This can be very difficult to understand, but you have made it very easy. I love your videos. Keep up the good work!
glad the website is still available.
I managed to get in. we actively make sure we're not suseptable to sql injection. its easy to avoid so theres no real reason to get hacked in this way.
oh man I remember doing this back in elementary school way bad when everything was vulnerable to SQLi. this took me back as that exact query was what I used but mine had a bit added at the start 😉
I tried this on one site and even though it didn't work, the site totally started malfunctioning
This shouldn't work but, sometimes it does. CHECK YOUR DAMN INPUTS, DEVS!
Ahhh... Discovering that I have more work to do in terms of making my final year project secure is always refreshing
Hi Chuck, just wanted you to know Cybersec was my most hated subject in college and you just made me like it
fantastic video!
I'm a bit confused by what is happening to the single quote. Shouldn't the username of admin' OR '1' = '1' cause a syntax error as SQL would still see username = 'admin' ' (with two closing single quotes)?
Actually No it won't, cause second closing quote is sifted at the end of username (here admin' Or '1' = '1_)
You see where I'm putting underscore we need an single quote but we are not writing it in username cause the extra closing quote you mentioned will automatically work for it.
5:40 I’m not a huge SQL wizard but wouldn’t it check
1 = 1 AND password = password
first?
then the OR would only be true if you guessed the username right
Not if you ignore the password request syntax and 1=1 the username. It’s not this simple in the real world but it’s still fun lol
Correct AND has a priority of 6 while OR has a priority of 7. So AND will be evaluated before OR. Therefore both injections fall flat when the username is wrong. But it's rare when it's not admin or any variation of that.
Yes, I don't understand this... 5:32 says the AND operator is used by the admin verification and the passw verification? It's impossible. This hack seems possible only if you guess the user or the passw
@@dippolos Yes, But this will get you in not knowing either U or P....
Username:
' or user is not null or '1'='1
password:
{any string}
@@EthosAtheos What's the precedence of the logic operators?
You forgot to inform that this only works on website that use sql as a database and a site that is not secure from sql request (which most websites do )
That’s pretty obvious. This is just to teach people what a SQL injection actually is and how it works
Your work shows the kind of person you are-efficient, organized, and result-oriented. Well done, Adrian Ruthnik. You are great at what you do. I appreciate your efforts and dedication. May you continue to show your worth and skills like this in the future.
Even as a seasoned IT professional, I find Adrian Ruthnik’s work highly informative and straightforward. Your advice and assistance have been invaluable.
Lol I didn't even get to SQL inject on the target, my first guess of the username and password was right 🤣
ikr lol
IYKYK
Very cool!
How can you view that syntax error info like in the example where there is an extra quotation?
Most of the time the server would print some data, redirect you, or give you a straight up error message.
Thank you so much for the content that you put out, you have launched me into a passion for cybersecurity. All of your videos are helping the community out in a positive way.
Bro. You are just crazy. I didn't see any tutorials on entire internet like you made.
I BROKE INTO THE WEBSITE IN LITERALLY 2 SECONDS
Where to run this code
@@Suchit_Plays_Song you run this code in the login area (it somewhere on the top left) and you do it in the username part
I’ll report you to the police if i found all of your name
@@Brakolligood joke...
Or just use sqli injector tool to test sites with dorks. Yeah it may not be targeted to a specific site but it’s possible
I couldn’t figure out how to hack the website, I feel like an idiot, especially since the top comment is a bunch of plp who figured it out 😭😭😭
Me too bro😢
Thanks for the practice, I just hacked the Altoro site using the admin' - -. I'm currently a student of Software Development and my cohorts and I are now learning some basic cybersecurity practices. Been following your channel for a few years now. I had a friend recommend me to your channel a long time ago. I remember the first video of yours I saw was an intro to python if my memory serves me right. Funny thing is after our mini cybersecurity course, next up for my class and I to learn is python. Thanks for the content and I'm happy for you and your channel!
I’m really struggling to get in. Probably making a silly mistake but please let me know how you got it to work (inc. the password)
I have encountered many IT professionals in my career, but few match the caliber of Adrian Ruthnik. His proactive approach and relentless pursuit of excellence make him a true standout. The way you handled my case with such care and precision is something I will always be grateful for.
Often only ID is used in the query and password is compared in server aide using time resistant functions.
Thanks for the great content Chuck!
I have a question: Since the sql statement contains username="admin" OR "1"="1" AND password="whatever", why does the AND operator use the password and the username instead of the password and "1"="1" even thought "1"="1" is right next to the password?
See it this way,
username="admin" OR "1"="1" AND password="whatever"
We can write this as,
TRUE OR TRUE AND FALSE
TRUE OR FALSE (AND is getting solved with the boolean at it's right and left)
TRUE
This means even if you'll write
'1' = '2' instead of '1' = '1'
The SQL Injection works fine
@@SakshamSinghania Oooh I get it now. So the OR is just used to "eat up" the AND, since the "admin" username is TRUE anyway. Thank you!
@@SakshamSinghania what do you do if you don't know the sites username???
@@that.03gt set the user name to this: ' or user is not null or '1'='1
its the same but results in
select * from users where username= '' or user is not null or '1'='1' and password = {whatever password}
The and statement " '1'='1' and password = {whatever password}" will evaluate false
, username = '' will evaluate false
, but "user is not null" will return all users who are not null, that is basically all the users if the system makes any sense.
The code is then so sloppy it uses the admin account. Probably because it is the first account, but I didn't keep digging. My goal was to get in without knowing the username once I did that I stopped looking.
I did try "username is not null" but got this error:
"Column 'USERNAME' is either not in any table in the FROM list or appears within a join specification and is outside the scope of the join specification or appears in a HAVING clause and is not in the GROUP BY list. If this is a CREATE or ALTER TABLE statement then 'USERNAME' is not a column in the target table."
I guessed that it was user and not username based on that error and naming conventions.
hope this helps.
@@stylem8132 I dont understand, the AND has to be both true to get access right? I dont get it how the OR eat that up
Great video as always. Do you know of any websites or ways I can practice phishing attacks legally? I like the idea of being able to maneuver through my opponent’s head to get them to do something, and if I can troll them by getting a Rick roll to pop up I think it’d be funny 😆
Edit: autocorrect
Phishing is only illegal if your intentions are illegal. But the nature of websites is that there would never be a website you could practice phishing on, because the members would know what they signed up for so they would suspect it. If you really want to do it just gather a list of emails and send an email to them

When building a website it's recommended to perform a regex user input filter to strip of any input that isn't a-z and 0-9 before posting to the server and on receiving a request in the server it's recommended to perform same regex filter before performing sql queries. This will strip off any sql injection input by the user.
or you can just use prepared statements
You're the best dude, you make codeing fun again.

Your OR-injection is not working unless the password is right... the order of the checks still matter and it will result in a boolean expression of (false OR true AND false) which still evaluates to false. This is because - and you are right about that - AND will evaluate first, but it will evaluate "1 = 1" together with "password = ..." which is only true if the password is correct.

This was an amazing explanation. Really loved the visuals.
Because of this video I was able to stop a huge vulnerability in my app. ❤ Thank you
Crazy - did admin'-- for user but no luck. Did it for password as well and it worked. Thanks Chuck
I can’t do it tho that’s a lexical error

THANK YOU!! i was seeing a loyt of videos explaining how to avoid sql injection but not one explaining how to actually inject it (which is important to know how to avoid it).
thanks a lot for the great explanation
the way you explain stuff is just magic
