Netsky and Sasser Worlds Deadliest Virus

A computer virus is a type of malware that, when executed, replicates by inserting copies of itself (possibly modified) into othercomputer programs, data files, or the boot sector of the hard drive; when this replication succeeds, the affected areas are then said to be "infected".^[1][2][3] Viruses often perform some type of harmful activity on infected hosts, such as stealing hard disk space or CPUtime, accessing private information, corrupting data, displaying political or humorous messages on the user's screen, spamming their contacts, or logging their keystrokes. However, not all viruses carry a destructive payload or attempt to hide themselves—the defining characteristic of viruses is that they are self-replicating computer programs which install themselves without the user's consent.

A basic explanation of cryptography.

Before I begin, I'll be using these terms a lot:

'Cryptography' is "the field concerned with linguistic and mathematical techniques for securing information, particularly in communications."

'Encryption' is "the process of obscuring information to make it unreadable without special knowledge."

A 'Cypher' or 'Encipherment' is "an algorithm for performing encryption (and the reverse, decryption)  a series of well-defined steps that can be followed as a procedure."
(wikipedia.org)

Cryptography has played a major role in history, and has effected the outcome of many wars. Knowledge is power, which is especially true on the battlefield. If you know your enemy's plans, you can win a war with an army half the size.

How to Spoof Caller ID – Caller ID Spoofing

Caller ID spoofing is the act of making the telephone network to display any desired (Fake) number on the recipient’s Caller ID display unit instead of
the original number. With this, it is possible to make a call appear to have come from any phone number that the caller wishes.

Have you ever wondered to know how to perform this? Read on to know more information on how to spoof Caller ID.

Unlike what most people think, an incoming call may not be from the number that is displayed on the Caller ID display unit. Because of the high trust that the people have in the Caller ID system, it is possible for the caller to easily fool them and make them believe that the number displayed on the Caller ID display is real. This is all possible through Caller ID spoofing.

How to create jar virus..?

This paper explains how to create a virus, that infects runnable Java Archive Files (JAR) while preserving their functionality. I invented this technique, but I think it is something you can easily come up with once you know how a JAR works.

The emphasis lies on the infection technique, not on doing harm or hiding the virus from detection, which would be a whole topic by itself.

I. The Java Archive File

At first you need to know how your host program actually works to preserve the functionality of the host. A JAR file is a ZIP file with the file ending .jar and a file named MANIFEST.MF in it. The JAR usually contains Java Bytecode.

How to Back trace Key loggers..?

Now all key loggers and Rats are sending data to the hacker in regular intervals (usually every 5 to 10 minutes) by using one of the two methods below:


1. Using the Emails: where hacker configures his email ID and password while creating the server. Key logger records the key strokes in a temp file and sends it to the hacker in form of emails. But this has a limit as most free email servers like Gmail or Yahoo or Hotmail has limit of 500 composed and received mails. So most hackers use the second method.

What is Bot Nets...?

Bot Nets.
--------------------------------

A botnet is a collection of infected computers under the control of one or more attackers. These botnets are used for a variety of criminal purposes -– all of which pose serious risk to the infected user as well as to the entire Internet community.

Once your computer is under the control of a botnet, it may be used to spam others, host phishing sites and other illicit files, infect or attack others, or have adware and spyware foisted on it so the attackers can collect from various affiliate advertising programs.

Even worse, many of today’s threats include keylogging capabilities. Of special interest to the attackers are your personal financial details – once stolen they are used for everything from credit card fraud to outright identity theft. In short, it’s not just your computer at risk – it’s your wallet.

How Big Are Botnets?

The botnet population is huge. According to a study by McAfee, "at least 12 million computers around the world (are) compromised by botnets." That means the botnet operators are controlling a population roughly the size of Guatemala. In fact, the number of infected systems would place it at about 70 out of 230 sovereign states and territories. More than Greece, bigger than Hungary, Belgium, Portugal or Cuba, and just a million behind Zimbabwe and Ecuador. The Czech Republic, Bolivia, Sweden, and the Dominican Republic would all be smaller.

While broadband users are favorite targets, dial-up users are equally vulnerable. Various studies have demonstrated that an unpatched, unprotected system can be compromised in as little as 5 minutes online. And if you're thinking it can't happen to you, think again.
What Do Botnets Do?

It's all about the money. Viruses, worms, and Trojans have evolved far beyond the childish pranks of yesteryear. Today's attackers are serious criminals -- in it for the money -- and your system spells international currency.

Botnets are used to steal credit card numbers, siphon intellectual property from companies, relay spam and other unwanted email, launch DDoS attacks, and any other actions desired by the attackers. A botnet is really nothing more than a cloud-based distributed network under the remote control of criminals.

Space on botnets can be leased by other attackers. Botnet operators get somewhere between 15 to 40 cents per infected computer, which means they need thousands of infected computers to make serious cash. And with all the focus on money, and not on notoriety, you can bet they'll make every effort to stay under your radar and get onto your system.

What is RAT...?

 RAT : Remote Access 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.
