Buffer Overflow

Hackers utilize multiple means to create malfunctions in an application. Buffer overflow is one of the most popular methods. With buffer overflow, a hacker overloads the server by introducing a flaw into an Internet form and then sending excess information. When the load overflows the limits, resulting web server crashes can occur. Buffer overflow has become a very popular tool used by hackers today.

How does a hacker execute buffer overflow? Numerous websites display forms on their web page for the purpose of having visitors fill in information. An example is where an e-commerce site asks customers to complete a form with personal information for the purposes of registration. Every specific field in the registration form accepts a maximum number of characters (limited within the HTML source code). A savvy hacker can implement certain alterations in the source code setting, thus permitting the browser to ask for higher character limits. The hacker then changes the form and types longer characters in each given field, and then submits the form. Once the form is submitted, the application in essence goes into a shock, as it was not designed to accept the lengthened character status. Thus, the application is forced to overflow parts of its memory. This may result in a system crash.

Buffer overflow is the best way to crash the system or make an application execute commands on behalf of the hacker. What are the ultimate consequences of this? Buffer overflow techniques can make servers dysfunctional and cause websites to stop functioning.
