An Introduction to Cross Site Request Forgery CSRF and How Developers can Mitigate the Attacks

Cross-Site Request Forgery, also known as XSRF, is a type of security attack on the web application that exploits the trust between a user and a website.

XSRF is an attack that takes advantage of the trust between a user and the website they are accessing by using malicious code to trick them into performing actions on behalf of the attacker.

This type of attack is commonly used to steal information from websites where users are required to log in.

The attacker will create a malicious link that tricks the victim into logging in on their behalf.

Once logged in, the attacker may be able to access sensitive information like usernames, passwords, credit card numbers or other personal data.

The victim may not even know they have been duped until it’s too late.

Cross Site Request Forgery is a type of attack that exploits the trust between two sites. A malicious site can send a request to a vulnerable site which then executes the request as if it originated from the victim site.

Cross Site Request Forgery is wreaking havoc on many websites because it bypasses authentication and authorization. The attacker can use this vulnerability to send malicious requests to other sites, thereby gaining access to sensitive data or even take over the account of other users.

5 Safeguards Developers can Create to Mitigate CSRF Attacks (keywords: csrf protection, csrf defense, cross site request forgery prevention, how to protect against csrf attacks)

CSRF attacks are a type of attack that exploits the trust that a user has in a site to execute commands on behalf of the user without their knowledge.

The following list provides 5 safeguards developers can create to mitigate CSRF attacks:

– Use an anti-CSRF token in each request

– Implement CSRF tokens in session cookies

– Include anti-CSRF tokens with AJAX requests

– Add an extra parameter to all POST and PUT requests

– Generate anti-CSRF tokens unpredictably

A Complete Guide on How to Prevent CSRF in AngularJS Applications by Leveraging Guards and HTTP Verbs

Cross-site request forgery (CSRF) is a type of malicious exploit of a website. It happens when the victim is tricked into loading an HTML page that contains a request to the vulnerable site.

This article will discuss how to prevent CSRF in AngularJS applications by leveraging guards and HTTP verbs.

A CSRF attack can be prevented by using AngularJS’s built-in cross-site request guard, which prevents access to unauthorized pages by verifying that requests are coming from authorized pages. This can be done by leveraging HTTP verbs, which are used in the browser to specify different types of requests.

The article will also cover how to use Angular’s built-in protection against CSRF attacks, which is called cross-site request guard (CSRF).

What is Cross Site Request Forgery (csrf) and How is it Wreaking Havoc?

Cross Site Request Forgery is a type of attack that exploits the trust between two sites. A malicious site can send a request to a vulnerable site which then executes the request as if it originated from the victim site.

Cross Site Request Forgery is wreaking havoc on many websites because it bypasses authentication and authorization. The attacker can use this vulnerability to send malicious requests to other sites, thereby gaining access to sensitive data or even take over the account of other users.

CSRF is a type of attack that tricks the victim into making an unauthorized HTTP request to a web application. This kind of attack is usually done by injecting malicious code into a website or by tricking the victim into clicking on a link which leads to the website.

In this article, we will be going through how to do CSRF attack step by step practical from scratch

The first thing you need to do is open up your favorite text editor and create a new file called index.html and save it in the same directory as your current directory. Next, we will want to create our form that will trigger our CSRF attack. We will use HTML for this purpose and we’ll just write out the form tags with some dummy text inside them for now:

Cross-Site Request Forgery (csrf) Attacks Code Example

To illustrate a CSRF attack, take an eCommerce website, examplebuy.com, that uses GET requests to accept purchases from customers. We’ll show how attackers can use CSRF to purchase products using other user’s accounts.

1. Attacker observes URL request format

The attacker observes that purchase requests on the website are in this format. 

GET https://examplebuy.com/shop/purchase?productid=3441&amount=200&address=33&20Park%20Drive%20NY%20NY HTTP/1.1

The request assumes that the user has an open session with the website. It uses an address ID to reference an address defined by the legitimate user.

2. Attacker crafts a forged request URL

The attacker now creates a forged URL that will purchase a product with a high purchase price, using another user’s account.

GET https://examplebuy.com/shop/purchase?productid=5776&amount=2000&address=45%20Main%20Street%20NJ%20NY HTTP/1.1

The attacker manipulates three parameters in the request—changing the product to a product they want to buy, changing the amount, and using their own address.

3. Attacker hides the URL in an image

There are a number of ways to get the user to load the forged request URL. A common tactic is to hide the URL in an image tag, and embed it in an email sent to the victim, or a website they will visit. The image tag would look like this:

<img src  = “https://examplebuy.com/shop/purchase?productid=5776&amount=2000&address=45%20Main%20Street%20NJ%20NY” width=“0” height= “0”>

4. Attacker uses social engineering to get the user to load the image

The attacker sends a phishing email to the victim, which either directly includes the image, or includes a link to a web page that embeds the malicious image tag. The URL is loaded on the user’s device.

5. Ecommerce site receives the forged request

Assuming that the user has an active session with the ecommerce site, when the URL is loaded, the website receives the forged purchase request. The website cannot identify that the request was not made directly by the legitimate user. It obeys the request and sends the goods to the attacker, billing the legitimate user’s account.
