Introduction to Computer Virus !

Computer virus is code in a host which has its source which is external. Its main intention is to gain resources in host which is not legitimate in normal case.

There is a fancy expansion for VIRUS i.e Vital Information Retrieval Under Siege. Mark Ludwig in his book titled “The Gaint Black Book of Computer Virus” expresses that all the virus can be broadly classified into three types. They are: i)Over writing ii)Companion iii)Parasitic. All the malicious code will exhibit either or all of the above mentioned basic behavior.

To play with code ,especially virus it is really essential to get closer to the machine. In the sense, it is necessary to learn the assembly language(May be 8086).

And this is it for intro! Hope that I would find time to post further details in the upcoming posts.

Event Sourcing with CQRS.

The way event sourcing works with CQRS is to have part of the application that models updates as writes to an event log or Kafka topic . This is paired with an event handler that subscribes to the Kafka topic, transforms the event (as required) and writes the materialized view to a read store.

Procedure to enable wireless LAN adapter in vmware!

I have went to find the way in which wlan in Kali Linux could be made listed my airmon-ng command. Most of the videos and posts suggested me that it is necessary to have another wi-fi adapter to have connected to wifi network. But this is not necessary. The procedure to do this is as follows: 1. Download this package in Virtual Machine(Kali linux) " http://wireless.kernel.org/download/compat-wireless-2.6/compat-wireless-2010-06-26-p.tar.bz2" 2.Unzip this package in terminal i.e navigate to place where you have downloaded this file , say desktop then type : cd Desktop for unzip type : tar -jxvf compat-wireless-2010-06-26-p.tar.bz2 3. Navigate into the uncompressed directory and type: i."make unload" (only words within the quotes are the commands) ii."make load" Done! now airmon-ng should have the list of the required devices.
