Commercial keyloggers supporting numerous functions and protected against detection may cost dozens and even hundreds of dollars. However, it is not that difficult to create a homemade keylogger and avoid antivirus alerts. In this article, I will explain how to do this; concurrently, we will practice our C# coding skills.
The Editorial Board decided to publish this material after reviewing a large number of articles in various periodicals, including technical ones. All these publications, with no exceptions, repeat the same trivial recommendations: “use a complex screen lock code”, “enable the fingerprint scanner”, “disable Smart Lock”, “make use of two-factor authentication”, and the most sarcastic recommendation for many Android users: “update your OS”. No doubt, all these steps make sense, but are they sufficient to make your phone secure? We believe not.
In March 2019, the National Security Agency of the US Department of Defense (NSA) has published Ghidra, a free reverse engineering toolkit. A couple of years ago, I had read about it on WikiLeaks and was eager to lay hands on the software used by the NSA for reverse engineering. Now the time has come to satisfy our curiosity and compare Ghidra with other tools.
Underground forums are full of offers to hack an account or two (or sell you the login credentials of some ten million accounts if you like). In most cases, such attacks involve phishing (sorry, social engineering) and use fake authentication pages. However, this method is ineffective if the user gets pushed a prompt or receives a text message with a six-digit verification code. I am going to demonstrate how to breach the two-factor authentication system by hacking a Google account belonging to one of this magazine’s humble editors.
Jeder Reverse Engineer, Malware-Analyst und einfacher Forscher stellt mit der Zeit ein bewährtes Set von Hilfstools zusammen, die er täglich für das Analysieren, Entpacken und Cracken anderer Software verwendet. In diesem Artikel besprechen wir meine. Sie werden für diejenigen nützlich sein, die über kein eigenes Set verfügen und erst mit dem Studium dieses Themas beginnen. Aber auch ein erfahrener Reverse Engineer sollte sich dafür interessieren, was andere Cracker verwenden.
Every reverse engineer, malware analyst or simply a researcher eventually collects a set of utility software that they use on a daily basis to analyze, unpack, and crack other software. This article will cover mine. It will be useful to anyone who has not yet collected their own toolset and is just starting to look into the subject. However, an experienced reverse engineer must also be curious about what other crackers are using.
Since such devices as bladeRF, HackRF, RTL-SDR, and software systems like GNU Radio had become widely available, reverse engineering of radio air data got really simple and entertaining.
