What is a JavaScript Hack?

A JavaScript hack is an act of manipulating code to either gain access to restricted information or to optimize a website’s performance. JavaScript is the most popular programming language and as such there are both advantages and disadvantages when utilizing this language to run a website of any form. Based on the intention behind the developer or the hacker, a JavaScript hack can be leveraged to fulfill both the productive and detrimental objectives for a website.

  • The positive advantage behind a JavaScript hack is that it has the ability to truly enhance the speed and functionality for any site. With an optimized code, developers can provide a more efficient browsing experience as well as save the developer time when writing the JavaScript code itself. Below are some benefits that are intended to provide a more efficient and speed optimizing script. 
  • Minifying Code: For developers, writing code for a specific action can take many forms and combinations. Ultimately, the code written for a website should be straightforward and achieve the objective that the developer has intended. With performance optimizing JavaScript hacks, originally long lines of code can be modified to be shortened down and made more efficient.  
  • Make Code Difficult for Hackers: The additional benefit for developers employing these JavaScript hacks is the appeal of preventing hackers from manipulation. By presenting a modified and condensed array of code hackers will need to spend more time understanding the structure and finding vulnerabilities not so easily displayed. In addition, with the additional time hackers spend attempting to infiltrate a website’s code, developers can begin to detect the intrusion and be able to act promptly before any malicious code has been uploaded. 
  • JavaScript Hack Implemented by Attacks
  • Just as there are benefits to JavaScript hacks, it would be careless to avoid mentioning the real methods and ways that attackers can infiltrate and inject malicious code. Below are some common JavaScript hacks that attackers frequently employ. 
  • Malicious Code: The most obvious JavaScript hack that can occur is when attackers inject malicious code into a website. With potential JavaScript library vulnerabilities, attackers use this as a window to insert whatever manipulation and damage their malware intends for. While there are various tactics to implement malicious code, attackers most commonly use the form of XSS or Cross-Site Scripting. This JavaScript hack essentially targets the user that is visiting the site. Through the user’s browsing session, hacking can gain access and begin to disseminate malicious code through the user’s actions. 
  • Tracking Browser Habits: Another common method of a JavaScript hack occurs through the consistent tracking of a user’s browsing habits and behaviors. While browsing cookies can assist both the developer and the user to maximize efficiency and save browsing time, attackers can directly extract this sensitive data which can lead to potential theft and fraud of a user’s information. For attackers to gain access to this information, a user doesn’t need to click on anything specific as the act of loading is sufficient enough to complete the hack.
