Reverse Engineering a JavaScript Obfuscated Dropper

1. IntroductionNowadays one of the techniques most used to spread malware on windows systems is using a JavaScript (js) dropper. A js dropper represents, in most attack scenarios, the first stage of a malware infection.It happens because Windows systems allow the execution of various scripting language using the Windows Script Host (WScript). This mean

Top 8 Reverse Engineering Tools for Cyber Security Professionals

Whether it is rebuilding a car engine or diagramming a sentence, people can learn about many things simply by taking them apart and putting them back together again. This process of breaking something down to understand it, build a copy to improve it, is known as reverse engineering.The process of reverse engineering was originally applied to hardware

Hacking Tools: Reverse Engineering

Reverse engineering refers to the duplication of another producer’s product following a thorough examination of its construction or composition. It involves taking apart the product to understand how it works so as to enhance or duplicate such a product. It makes it possible to understand the basic working principle and structure of the systems u

[CRITICAL] Nissan Leaf Can Be Hacked Via Web Browser From Anywhere In The World

What if a car could be controlled from a computer halfway around the world? Computer security researcher and hacker Troy Hunt has managed to do just that, via a web browser and an Internet connection, with an unmodified Nissan Leaf in another country. While so far the control was limited to the HVAC system, it’s a revealing demonstration of what’s possible.
