5/19/2023 0 Comments Javascript email obfuscatorWe also insert a function called indexToLiteral in the AST of the script. In the src/ directory, we create a file called SimpleFingerprintCollector.js.Ĭlass SimpleFingerprintCollector )) We use a simple fingerprinting script with few attributes so that it is easier to understand. Nevertheless, one should be careful when using obfuscation since it is not perfect with enough time and effort, attackers can often understand Thus, attackers can look at the content of the script, hence the need for obfuscation. Quickly Conceal Your Email Address You can use our handy tool above to mask your email address either using the simpler HTML method or the JavaScript method as we discussed above. Indeed, since JavaScript is executed in the browser, it needs to be sent to the user’s machine to be executed. JavaScript offers the highest level of protection against harvesting and makes it safer to list your email address. So that attackers can’t too easily understand the different attributes collected. In the case fingerprinting is used in a security context, companies often tend to obfuscate the content of their script In this post, we’ll only focus on the JavaScript part of fingerprinting.īrowser fingerprinting can be used both for tracking as a way to regenerate cookies or for security,Īs a mechanism to detect bots and crawlers, as well as to enhance authentication. ![]() To collect these attributes, we can leverage the HTTP headers sent by the browser as well as JavaScript APIs. Nevertheless, I provide a brief explanation of what’s browser fingerprinting.īrowser fingerprinting is a technique that collects a set of attributes related to the user device and browser. No knowledge of browser fingerprinting is required to understand the remainder of this post. To better understand the obfuscation transformations, we use a short browser fingerprinting script as an example on this blog post. Nevertheless, if you’re just interested in the obfuscation part, you can skip the next section. In this blog post, I try to provide a complete working example. Transpiled or obfuscated versions of these files.įinally, the test/ directory will contain files used to test if our code still works after obfuscation. The src/ directory will contain the source of the JavaScript files we write, while the dist/ directory will contain
