When it comes to ethical hacking, one of the critical skills you need to succeed is the usage of various tools to start your penetration testing process. While browser extensions may not be the most popular, they can actually help you achieve a variety of objectives, ranging from crawling an entire website to hijacking protected test sessions.
By installing this extension, you can work much faster because it automatically clears the browser cache before loading a new page. You can also easily enable or disable the plugin with a single click.
One of the most popular topics discussed on computer help bulletin boards is browser hijacking. In most instances, computer users want to know how to protect themselves from malicious intrusions and outside control.
Browser hijacking occurs when unwanted software on an internet browser alters the activity of the browser. Internet browsers serve as the "window" to the internet, and people use them to search for information and either view it or interact with it.
However, it doesn't take a super criminal to install software in a user's browser. Some marketing companies take the same steps to follow activity on the internet to see the sites users visit and how long they spend on those web pages. They then either use the information themselves to target their ad campaigns or sell it to other companies that use the data to focus their marketing content.
The most pernicious form of browser hijacking occurs when a vendor forces a new and unauthorized software program directly into the browser itself. The intruding application could take up a significant amount of space on the browser's toolbar.
Some antivirus software alerts users to the presence of adware and spyware, but some new malware could go undetected, or the security software might be unable to root out the intruder. In these cases, users have to reinstall their browsers to regain control of the interface.
In extreme instances, the hijacking program reinstalls itself in the browser, and users may have to erase the contents of their computer, install a fresh operating system and the most current browser version, and restore their personal files from a backup.
Protecting against browser hijacking is challenging. Frequent cleaning of directories with browser cookies and histories helps. It's also critical to install and maintain quality antivirus software to stop malware from installing itself onto browsers. The security software should alert users to unauthorized installation attempts and ask how to proceed. This reduces the risk of infection.
The solution is extremely simple. I found someone explaining online how to run Javascript code in Firefox bookmark and how to make it executable for the address bar. (I assume that you use Firefox or other privacy-respecting web browser. I would personally not paste any API key to a Chrome bookmark, as those get scanned, and there were reports of DMCA takedowns on private bookmarks!)
Browserhacks is an extensive list of browser specific CSS and JavaScript hacks from all over the interwebs. Press the first letter of a browser to jump to the according section, like F for Firefox.
Browserhacks is mostly based on the big list of CSS browser hacks by Paul Irish. Other posts like Moving IE specific CSS to media blocks by Keith Clark, Detecting browsers with JS hacks by Gareth Eyes and IE CSS hacks by Nicolas Gallagher greatly helped.
Tamper Data Mozilla Firefox extension that can modify and view HTTP requests before they are sent. It will show what data the web browser is sending on your behalf such as hidden form fields and cookies.
The browser in the host machine sends a request to a virtual host that is pointing to the IP of the virtual machine. Inside that VM we have a nginx server listening. The server then proxy pass the request to an external API.
We will explain what BeEF is, how to install it, and how to start it up. We will explore the BeEF web interface and discuss its different components. Additionally, we will explain how BeEF can hook into web browsers, and provide two methods to achieve this.
BeEF has a web-based user interface that allows control over "hooked" web browsers, providing a clear overview of browser details, activity logs, and available command modules. The "hook.js" is a JavaScript file central to BeEF's operation; once loaded by a target's browser, it establishes a communication channel with the BeEF server and gathers comprehensive information about the browser environment.
In-Depth Browser Analysis: BeEF can provide detailed information about the hooked browsers, such as the browser type, version, installed plugins, whether the browser is running over Tor, cookies, etc.
Client-Side Exploitation: BeEF has numerous command modules that can aid in exploiting web browsers. These modules can perform various tasks such as stealing cookies, conducting social engineering attacks, launching network attacks, and more.
Browser exploitation refers to taking advantage of security vulnerabilities in a web browser to perform unauthorized actions. This can involve various techniques, typically to gain control over the browser or the system on which it's running or to steal sensitive information.
The basic concept behind browser exploitation is that a web browser, like any software, can have flaws or vulnerabilities in its code. These vulnerabilities could cause the browser to behave in unintended ways.
With BeEF, an attacker can leverage this widespread use of JavaScript to "hook" a browser, allowing the attacker to exploit potential vulnerabilities, execute commands, and potentially gain unauthorized access or extract sensitive information.
From the details pane, BeEF provides us with a wealth of information. Valuable insights include the browser being utilized, its version, the operating system it runs on, its architecture, platform information, language details, installed plugins, and much more.
Another way to hook a browser is via XSS (Cross-Site Scripting). Cross-site scripting is a vulnerability where an attacker loads JavaScript into a web application via user input. This attack could lead to the exposure of sensitive information.
When this module is executed on a hooked browser, it displays a fake notification bar at the top of the target browser window. The content of this notification bar can be customized and designed to trick the user into clicking a link or downloading a file.
Session cookies, also known as temporary cookies, store information about a user's activity for a single browsing session. They help websites remember a user's actions, such as login information or items added to a shopping cart and are deleted when the browser is closed.
However, the capabilities of BeEF extend far beyond what we've explored here. Diving deeper into its options and functionalities can significantly enhance your proficiency using the BeEF hacking tool.
But we all know this. People on our teams may not know that a browser contains a lot of functionality, which gives cybercriminals a big playground and endless possibilities to hack you. I would be so bold to say that the majority of the cyberattacks that we see are initiated via the web browser. Many of the lateral movement techniques are combined with information extracted from the browser, such as passwords, session tokens, and more.
By default, the web browser asks you to store passwords in your browser, and this is probably one of the most used functionalities that all browsers have in common. This feature was intended to make our lives easier by removing the challenge of remembering all those complicated passwords.
While storing your passwords in the browser sounds like an excellent idea, it also entails many limitations. Passwords stored in the browser are encrypted and stored in a database, but different operating systems and web browsers use different encryption techniques.
I think we all know what can happen if an attacker can get hold of all your credentials to every site that you choose to store your passwords. But the browser stores not only passwords but also session cookies. An attacker can use session cookies to log in to your account using your own session cookie, bypass known security session mechanisms, and multi-factor authentication using the stolen session cookies.
The modern web browser is almost like a small operating system. The main functionality of a browser plugin/extension is to either add a handler for a specific file format/extension or give you the possibility to use the information on the website in your own way. Here are a few examples.
Apart from plugins, browsers also use extensions which are not the same as plugins/handlers. The extension is built-in to add extra functionality to the actual web browser. It allows the user to manipulate the source code on the website from inside the browser. For example, there are AdBlockers that simply remove unwanted ads from the website. But tons of other extensions give extra functionality, such as downloading video files from the websites instead of just streaming the video.
Each Chrome extension uses a unique name; under each name we can find the version number and the manifest.json file. The JSON file is a configuration file informing the browser what the extension can do and which files in the extensions file system are accessible remotely. This setting is controlled by the variable web_accessible_resources; in the screenshot below, you can see how I look for all web-accessible resources.
If you are running a vulnerable device in your home network and you are visiting a malicious website via your phone or computer, it is possible for the attacker to tell the browser to send a request to your internal networks.
With this trick, attackers can inject malicious code into websites and infect them with a payload. The payload will enumerate your internal network for vulnerable devices and once a device is found the hijacked browser will automatically exploit it.
