  1. Hesperbot DGA : Everything is Dynamically generated using GA

    Hesperbot DGA : Everything is Dynamically generated using GA
    Our next contender for DGA series is Hesperbot. It generates all strings/object-names dynamically using various "Generation Algorithms"
    similar to DGA. Though its DGA differs from NGA (Name generation algorithm) used for name generation for objects like filenames, foldernames,
    mutexes etc.

    But both DGA & NGA utilises same seed generator. Hesperbot's DGA is free from date/time and generates ...
  2. Malware Emulation - An Introduction

    Namaste

    This post discuses the things from the point where reversing of any malware ends.
    The analysis of a malware is not enough to satisfy any researcher. There is no point

    There are mainly two ways:

    1. Any anti ASLR modules gets loaded into the target application. I mean you have the base address of any module at fixed location always even after the system restart.

    2. You get a pointer leak from a memory leak/buffer overflow/any zeroday. In this technique you can adjust the offsets to grab the base address of the module whose pointer gets leaked.
