![]() ![]() And please note that the string must have even number of characters for this to work. If you change this, make sure you change the characters string in JavaScript as well. Characters that are to be used when obfuscating email address. $emailLetters = array_reverse( $emailLetters ) ![]() $emailLetters = preg_split( ‘//u’, $email, null, 1 ) We will work with UTF8 characters, just to be safe that we won’t mess up any address. Function takes string as an argument and returns a string. E-mail deobfuscation (JavaScript & CSS)Ĭode is thoroughly commented, have a look if you’d like to know more.Therefore, as a last deobfuscation step, we’ll reverse the reversed address and remove added CSS rules as soon as the user hovers over the link. If user copies the address, or if he clicks it, he’ll get the reversed one. This will, of course, leave us with a usability problem. This way, users will see real address, but spam bots will still (even if they can parse JavaScript) see a reversed e-mail. When user opens the page we will detect which e-mail links have been obfuscated, apply reversed ROT13 algorithm on them and direction:rtl and unicode-bidi:override CSS rules. The function will reverse the address and obfuscate it using slightly modified ROT13 algorithm.ĭeobfuscation will be done with JavaScript. To handle this, we’ll create a PHP function that will take string (e-mail address) as an argument. Script should work on all desktop browsers (I’m talking IE6+here) and on mobile browsers as well (at least on the ones that support JavaScript).It should show obfuscated e-mail to bots, but real one to humans humans should not even notice that obfuscation (or deobfusaction) is taking place.User should work only with real e-mail script should obfuscate and deobfuscate it on the fly. ![]() It should function pretty much out of the box.In this tutorial I’ll show you how to create a script that will do just that.īasic requirements for such script (at least from my point of view) are: One of the ways to keep it safe is to obfuscate it. To keep this insane amount of spam out of your inbox, you should keep your e-mail safe when you display it on web. That’s around 200 billion spam messages per day. The title of this article was supposed to be “Top 9 Free Phishing Simulators.” However, after much searching, trying, visiting of broken links, filling out forms and signing up for mailing lists, it became clear that the combination of “free” and “top” really narrows down the selection to very few actual choices for phishing training.According to Wikipedia, more than 97% of all e-mails sent over the net are unwanted. The final list does not include any of the fishy (pardon the pun) apps that let you create a fake website or phishing site for collecting data. ![]() Nor are we including any of the free managed campaigns offered by so many now popular phishing services. We wanted to focus on tools that allow you to actually run a phishing campaign on your own, i.e. Simple tools that will allow you to craft a simple email message and send it to one or several recipients using a specified mail server.Note: Want more than just a phishing simulator? Check out our article on the best security awareness training.īasically, if you are looking for a free phishing simulator for your company, you are down to three choices: create and send at least one phishing email to a real recipient. Features like reporting or campaign management are often not an option, making them more like penetration testing tools than phishing simulators. This is a growing and interesting category, which makes up the majority of our list. With open-source, you get all the usual benefits, such as feature-rich free versions and community support. But all the usual shortcomings are there as well: tools like this usually require some significant technical skills to install, configure, and run. Additionally, most of them are Linux-based. So, if words like “missing dependencies” don’t sound like an alien tongue, then this category may be of interest to you. The majority of commercial phishing simulators are offered as software-as-a-service (SaaS). With those, you usually get the best of all worlds: ease of use, rich features (including reporting), technical support, etc. With phishing being among the top cybersecurity risks and commercial phishing simulators popping up like mushrooms after a rain, finding a free demo seems like an easy task. That is, until you actually try.In most cases, the best can you get after jumping through various hoops (filling out a request form, subscribing to a mailing list, confirming your email address, etc.) is a free campaign managed by the vendor, or a demo account with so many limitations that it doesn’t even give you a good understanding of the full version’s capabilities, let alone providing you with an actual tool that you can effectively use to create and manage multiple phishing campaigns. ![]()
