RAT Trojan

RAT stands for Remote Access Trojan or Remote Administration Tool. It is one of the most dangerous virus out their over the internet. Hacker can use RAT to get complete control to your computer. He can do basically anything with your computer. Using RAT hacker can install keylogger and other malicious viruses remotely to your computer, infect files on your system and more. In this post i will tell you about what hacker can do with your computer using RAT and tell you about some commonly use RAT by hackers.

What is RAT ?


As i have told you in my introduction paragraph RAT is Remote Access trojan. It is a peace of software or program which hacker uses to get complete control of your computer. It can be send to you in form of images, videos or any other files. There are some RAT that even your antivirus software can not detect. So always be sure about what you are downloading from the internet and never save or download files that anonymous user send you over the mail or in chat room.

What You Can do With RAT ?

Once a RAT is installed on any computer hacker can do almost anything with that computer. Some malicious task that you can do with RAT are listed below:

Infecting Files

Installing Keyloggers

Controlling Computer

Remotely start webcam, sounds, movies etc

Using your PC to attack Websites (DDOS)..

Whatsapp Blue Ticks : An overview

Hey guyss..
 As we all know whatsapp is world`s no.1 Messaging app.
It is owned by Facebook.

Recently there was an update to the latest version of whatsapp where users sending the messages get a blue tick to see.

So, What does this Blue tick means ?

Actually this blue tick is the proof that the message has been read by the recipient.
Previously, the concept of two black tick was that the first tick conforms that the message has been sent and second tick conforms that the message has reached the recipient`s whatsapp account but there was nothing about when the message has been read.

Now providing one more feature in this category whatsapp now shows a blue tick which comes after the message is been read by the reader.


So now,,

one black tick means  MESSAGE SENT
two black ticks mean MESSAGE delivered
two blue ticks mean MESSAGE READ

it may sound quite interesting but at the same time its also disgusting as it may ruins life of several couples and young relationships....... :-)

IP Address ipv4 Explained



Every station on a PSN (packet switched network) that is based on the TCP/IP
protocol (your computer is one, for example. Yes, we're referring to a host
that is connected to the net) must have an IP address, so it can be identified,
and information can be relayed and routed to it in an orderly fashion.



An IP address consists of a 32 bit logical address. The address is divided
into two fields:



1) The network address:


Assigned by InterNIC (Internet Network Information Center).
In fact most ISPs (internet service providers) purchase a number of addresses
and assign them individually.



2) The host address:


An address that identifies the single nodes throughout the network. It can be assigned
by the network manager, by using protocols for it such as DHCP, or the workstation itself.



[The IP networking protocol is a logically routed protocol, meaning that address 192.43.54.2
will be on the same physical wire as address 192.43.54.3 (of course this is not always true. It depends on the

subnet mask of the network, but all of that can fill a text of its own)


IP address structure:


   ---.---.---.---

   ^             ^
   |             |
network    |    host

Every " --- " = 8 bits.
The first bits ===> network address
The last bits  ===> host address.
with 8 bits you can present from 0-255 . (binary=(2 to the power of 8)-1)

Example:
11000010.01011010.00011111.01001010 (binary)
194.90.31.74 (decimal)
IP address CLASSES :
We can classify IP addreses to 5 groups. You can distinguish them by comparing the "High Order" bits (the first four bits on the
left of the address):

type  | model  | target | MSB |addr.range    |bit number| max.stations|
     |        | groups |     |              |net./hosts|             |
------|--------|--------|-----|--------------|----------|-------------|
 A   |N.h.h.h | ALL    |  0  | 1.0.0.0      |   24/7   | 16,777,214  |
     |        | ACCEPT |     |    to        |          |             |
     |        | HUGE   |     | 127.0.0.0    |          |             |
     |        | CORPS  |     |              |          |             |
-----------------------------------------------------------------------
     |N.N.h.h | TO ALL | 10  | 128.1.00     | 16/14    | 65,543      |
 B   |        | LARGE  |     |    to        |          |             |
     |        | CORPS  |     | 191.254.00   |          |             |
-----------------------------------------------------------------------
     |N.N.N.h |TO ALOT | 110 | 192.0.1.0    | 8/22     |  254        |
 C   |        |OF      |     |    to        |          |             |
     |        |SMALL   |     | 223.225.254  |          |             |
     |        |CORPS   |     |              |          |             |
-----------------------------------------------------------------------
D    | NONE   |MULTI-CA|1110 | 224.0.0.0     | NOT FOR |   UNKNOWN   |
     |        |ST ADDR.|     |    to         | USUAL   |             |
     |        |RFC-1112|     |239.255.255.255| USE     |             |
-----------------------------------------------------------------------
E    | NOT FOR|EXPERIME|1,1,1,1| 240.0.0.0     |NOT FOR|  NOT FOR USE|
     |  USE   |NTAL    |       |   to          |USE    |             |
     |        |ADDR.   |       |254.255.255.255|       |             |
-----------------------------------------------------------------------

N=NETWORK , h=HOST .



Notice the address range 127.X.X.X.
These addresses are assigned to internal use to the network device, and are
used as an application tool only. For example: 127.0.0.1, the most common one,
is called the loopback address - everything sent here goes directly back to
you, without even traveling out on the wire.
Also, some IPs are reserved for VPNs - Virtual Private Networks. These are
local area networks over wide area networks that use the Internet Protocol to
communicate, and each computer inside the network is assigned with an IP
address. So, suppose a certain computer wants to send a data packet to
another host on the network with the IP 'x', but there's also another host on
the Internet that has the same IP - what happens now? So this is why you
cannot use these and other forms of reserved IPs on the Internet.

EXTRA:

Distinguishing different groups:

You have to compare the first byte on the left in the address as follows:




Type |    First byte  | MSB
    |    in decimal  |
----------------------------
A    | 1-127          | 0
----------------------------
B    | 128-191        | 10
----------------------------
C    | 192-223        | 110
----------------------------
D    | 224-239        | 1110
----------------------------
E    | 240-254        | 1111
----------------------------


NOTES: Yes, we know, we've left A LOT of things unexplained in this text.
With time, we will write more tutorials to cover these and other subjects. So
in the meantime, I suggest that you go to http://blacksun.box.sk, find the
tutorials page and see if there's anything else that's interesting to you.
And remember - we also have a message board, so if you have any questions,
feel free to post them there.


weird shit (newbie note):

1) Multicast: (copied from RFC 1112)
  IP multicasting is the transmission of an IP datagram to a "host
  group", a set of zero or more hosts identified by a single IP
  destination address.  A multicast datagram is delivered to all
  members of its destination host group with the same "best-efforts"
  reliability as regular unicast IP datagrams, i.e., the datagram is
  not guaranteed to arrive intact at all members of the destination
  group or in the same order relative to other datagrams.

  The membership of a host group is dynamic; that is, hosts may join
  and leave groups at any time.  There is no restriction on the
  location or number of members in a host group.  A host may be a
  member of more than one group at a time.  A host need not be a member
  of a group to send datagrams to it.

  A host group may be permanent or transient.  A permanent group has a
  well-known, administratively assigned IP address.  It is the address,
  not the membership of the group, that is permanent; at any time a
  permanent group may have any number of members, even zero.  Those IP
  multicast addresses that are not reserved for permanent groups are
  available for dynamic assignment to transient groups which exist only
  as long as they have members.

  Internetwork forwarding of IP multicast datagrams(ip packets)is handled by
  "multicast routers" which may be co-resident with, or separate from,
  internet gateways.  A host transmits an IP multicast datagram as a
  local network multicast which reaches all immediately-neighboring
  members of the destination host group.  If the datagram has an IP
  time-to-live greater than 1, the multicast router(s) attached to the
  local network take responsibility for forwarding it towards all other
  networks that have members of the destination group.  On those other
  member networks that are reachable within the IP time-to-live, an
  attached multicast router completes delivery by transmitting the
  datagram(ip packet) as a local multicast.

  *if you do not understand the above do not worry, it is complicated and dry
  but reread it and read it again get a dictionary if it helps.
  Hacking is not easy.

2) MSB: Most Significent Bit:
  In set numbers the first number on the left is the most important because it
  holds the highest value as opposed to the LSB=> least significent bit, it
  always holds the the smallest value.

INTERNET - The Largest Network of the World

Good Afternoon Guyz.. Today I am sharing some information about INTERNET.
The Internet is a global system of interconnected computer networks that use the standard Internet protocol suite (TCP/IP) to link several billion devices worldwide. It is an international network of networks that consists of millions of private, public, academic, business, and government packet switched networks, linked by a broad array of electronic, wireless, and optical networking technologies. The Internet carries an extensive range of information resources and services, such as the inter-linked hypertext documents and applications of the World Wide Web (WWW), the infrastructure to support email, and peer-to-peer networks for file sharing and telephony.
The origins of the Internet date back to research commissioned by the United States government in the 1960s to build robust, fault-tolerant communication via computer networks.[1] While this work, together with work in the United Kingdom and France, led to important precursor networks, they were not the Internet. There is no consensus on the exact date when the modern Internet came into being, but sometime in the early to mid-1980s is considered reasonable.[2] From that point, the network experienced decades of sustained exponential growth as generations of institutional, personal, and mobile computers were connected to it.
The funding of a new U.S. backbone by the National Science Foundation in the 1980s, as well as private funding for other commercial backbones, led to worldwide participation in the development of new networking technologies, and the merger of many networks.[3] Though the Internet has been widely used by academia since the 1980s, the commercialization of what was by the 1990s an international network resulted in its popularization and incorporation into virtually every aspect of modern human life. As of June 2012, more than 2.4 billion people—over a third of the world's human population—have used the services of the Internet; approximately 100 times more people than were using it in 1995.[4][5] Internet use grew rapidly in the West from the mid-1990s to early 2000s and from the late 1990s to present in the developing world. In 1994 only 3% of American classrooms had access to the Internet while by 2002 92% did.[6]
Most traditional communications media including telephone, music, film, and television are being reshaped or redefined by the Internet, giving birth to new services such as voice over Internet Protocol (VoIP) and Internet Protocol television (IPTV). Newspaper, book, and other print publishing are adapting towebsite technology, or are reshaped into blogging and web feeds. The Internet has enabled and accelerated new forms of human interactions through instant messagingInternet forums, and social networkingOnline shopping has boomed both for major retail outlets and small artisans and traders. Business-to-business and financial services on the Internet affect supply chains across entire industries.

What is a computer Network

computer network or data network is a telecommunications network that allows computers to exchange data. In computer networks, networked computing devices pass data to each other along data connections. The connections (network links) between nodes are established using either cable media or wireless media. The best-known computer network is the Internet.

Network computer devices that originate, route and terminate the data are called network nodes.[1] Nodes can include hosts such aspersonal computersphonesservers as well as networking hardware. Two such devices are said to be networked together when one device is able to exchange information with the other device, whether or not they have a direct connection to each other.
Computer networks support applications such as access to the World Wide Web, shared use of application and storage serversprinters, and fax machines, and use of email and instant messaging applications. Computer networks differ in the physical media used to transmit their signals, the communications protocols to organize network traffic, the network's size, topology and organizational intent.
