Hackers exploit browser vulnerabilities to attack deep within networks
The Browser Hacker's Handbook gives a practical understanding of hacking the everyday web browser and using it as a beachhead to launch further attacks deep into corporate networks. Written by a team of highly experienced computer security experts, the handbook provides hands-on tutorials exploring a range of current attack methods.
The web browser has become the most popular and widely used computer "program" in the world. As the gateway to the Internet, it is part of the storefront to any business that operates online, but it is also one of the most vulnerable entry points of any system. With attacks on the rise, companies are increasingly employing browser-hardening techniques to protect the unique vulnerabilities inherent in all currently used browsers. The Browser Hacker's Handbook thoroughly covers complex security issues and explores relevant topics such as:
- Bypassing the Same Origin Policy
- ARP spoofing, social engineering, and phishing to access browsers
- DNS tunneling, attacking web applications, and proxying—all from the browser
- Exploiting the browser and its ecosystem (plugins and extensions)
- Cross-origin attacks, including Inter-protocol Communication and Exploitation
The Browser Hacker's Handbook is written with a professional security engagement in mind. Leveraging browsers as pivot points into a target's network should form an integral component into any social engineering or red-team security assessment. This handbook provides a complete methodology to understand and structure your next browser penetration test.

Sandbox is a good attempt at addressing this universal problem. Obviously, the degree to which developers will conform to this premise (that is, write vulnerable code) will vary depending on many complex factors, such as lack of sleep or coffee bean quality. The sandbox is simply a mitigating control. It attempts to encapsulate a high-probability area of browser compromise in a protective wall. It allows for an increased focus on a smaller attack surface. This provides a good risk-versus-reward.
The domain to specify which IP addresses are allowed to send e‑mails on its behalf. Figure 2-3: URLCrazy Output The scheme was introduced as a method to stifle spammers from sending e‑mails purporting to be from domains without their permission. SMTP servers receiving e‑mails from particular IP addresses can query the SPF records from the reported domain name and validate that the IP is allowed to send e‑mails. For example, the TXT record for microsoft.com includes: v=spf1.
Control examples you examined earlier. When that’s rendered, the browser sees the content and assumes it’s from the legitimate website. If an attacker is able to execute processes on a system, particularly if it occurs within the same processing space as the browser, then it’s generally game over for the victim. These types of malware often come with more features than just HTML injection, usually providing form grabbing, keystroke logging at the operating system level, and screenshot.
Value of [].constructor .prototype.join, which is the native code used when join() is called on an array. After 5 seconds, the join() method is called on the [1,2,3] array, and the printing function used previously is called again. The second call shows the difference, after the join() prototype has been overridden. If you have a look back at the first snippet of code, you can see where the join() prototype gets Chapter 4 ■ Bypassing the Same Origin Policy 147 overridden inside the.
