 What's a Hacker?

"Hacker" is one particular terms that has a different meaning depending on who uses it. As a result of Hollywood, many people think a hacker is someone who gains illicit access to some type of computer and steals stuff or breaks into military networks and launches missiles for fun.

Today, a hacker doesn't need to be a geek from a top university who breaks into banks and government systems. A hacker may be anyone, even the kid next door.

By having an ordinary laptop, everyone can download simple software off the Internet to see everything that goes into and out of some type of computer for a passing fancy network. And the people who do this don't will have the most effective of intentions. Hire a hacker to catch cheating spouse

A Brief History of Hackers

Nowadays, the word "hacker" is becoming synonymous with those who sit in dark rooms, anonymously terrorizing the Internet. However it wasn't always that way. The original hackers were benign creatures. In reality, they were students.

To anyone attending the Massachusetts Institute of Technology throughout the 1950s and 60s, the term "hack" simply meant an elegant or inspired treatment for any given problem. Lots of the early MIT hacks tended to be practical jokes. One of the very extravagant saw a replica of a campus police car wear top of the Institute's Great Dome.

As time passes, the word became associated with the burgeoning computer programming scene at MIT and beyond. For these early pioneers, a hack was an accomplishment of programming prowess. Such activities were greatly admired while they combined expert knowledge with an innovative instinct.

Why Does a Hacker Hack?

Hackers' motivations vary. For some, it's economic. They earn a full time income through cybercrime. Some have a political or social agenda - their aim is to vandalize high-profile computers to create a statement. This kind of hacker is named a cracker as their main purpose is to crack the security of high profile systems.

Others do it for the sheer thrill. When asked by the web site SafeMode.org why he defaces web servers, a cracker replied, "A high-profile deface gives me an adrenalin shot and then after a while I want another shot, that's why I can't stop." [1]

Today, we are confronted with a new kind of hacker - your nearby neighbor. Every single day, tens of thousands of people download simple software tools that enable them to "sniff" wifi connections. Some do this merely to eavesdrop on which others are doing online. Others do this to steal personal data in an endeavor steal an identity.

The Most Common Attacks

1. SideJacking / Sniffing

Sidejacking is a web attack method in which a hacker uses packet sniffing to steal a session cookie from an internet site you simply visited. These cookies are usually sent back to browsers unencrypted, even if the first website log-in was protected via HTTPS. Anyone listening can steal these cookies and then utilize them access your authenticated web session. This recently made news because a programmer released a Firefox plug-in called Firesheep that makes it simple for an intruder sitting in your area on an open network (like a public wifi hotspot) to sidejack many popular website sessions. Like, a sidejacker using Firesheep could take control your Facebook session, thereby gaining access to your entire sensitive data, and even send viral messages and wall posts to your entire friends.

2. DNS Cache Poisoning

In DNS cache poisoning, data is introduced in to a Domain Name System (DNS) name server's cache database that didn't result from authoritative DNS sources. It's an accidental result of a misconfiguration of a DNS cache or of a maliciously crafted attack on the name server. A DNS cache poisoning attack effectively changes entries in the victim's copy of the DNS name server, so when he or she types in the best site name, he or she is sent instead to a fraudulent page.

3. Man-In-the-Middle Attacks

A man-in-the-middle attack, bucket brigade attack, or Janus attack, is an application of active eavesdropping in which the attacker makes independent connections with the victims and relays messages between them, making them believe that they're talking directly to one another over a private connection, when in reality the whole conversation will be controlled by the attacker. The attacker must be able to intercept all messages going between the two victims and inject new ones. Like, an attacker within reception range of an unencrypted wifi access point can insert himself as a man-in-the-middle. Or an attacker can pose as an online bank or merchant, letting victims register over a SSL connection, and then a attacker can log onto the actual server using the victim's information and steal charge card numbers.

4. Smishing

Packet sniffers allow eavesdroppers to passively intercept data sent between your laptop or smartphone and other systems, such as for instance web servers on the Internet. Here is the easiest and most basic sort of wireless attack. Any email, web search or file you transfer between computers or open from network locations on an unsecured wireless network may be captured by way of a nearby hacker using a sniffer. Sniffing tools are readily available for free on the web and you will find at least 184 videos on YouTube to exhibit budding hackers how to use them. The only method to safeguard yourself against wifi sniffing in most public wifi hotspots is to employ a VPN to encrypt everything sent within the air.

5. Mass Meshing

Also called mass SQL injection, this can be a method whereby hackers poison websites by illegally imbedding a redirection javascript from legitimate websites previously infected and controlled by the hackers. These javascripts redirect the visitor's computer to servers which contain additional malicious programs that can attack a user's computer.

The Most Common Targets

Hackers are enthusiastic about many types of computers on the Internet. The following list describes several types of targets and their interest hackers. [2]

1. Corporate Networks

Corporate computers are often heavily fortified so hacking into one has high cachet. Behind corporate firewalls are repositories of customer information, product information, and sometimes, in the case of a software publisher, the item itself.

2. Web Servers

Web servers are computers which contain websites. Although some contain customer financial information, web servers are often targets for vandals because they may be defaced to show information the hacker chooses to the public.

3. Personal Computers

With the ever growing use of wifi, laptops are becoming one of the very hacked devices. Everything an individual visits online can be exposed to an individual using software to "sniff" that connection. The website URL, passwords used to log into an on the web banking account, Facebook pictures, tweets, and a whole instant message conversation may be exposed. It's the simplest type of hacking because it requires little skill.

4. Tablets and Palm Top devices

Tablets, cell phones, and other mobile-ready devices are just as popular as laptops have been in wifi hotspots. A hacker in a public hotspot could see a portable device, along with all data going into and from the jawhorse, in the same way easily as he is able to a laptop.

How You Can Protect Yourself

The easy the fact is that anyone connecting to the Internet is susceptible to being hacked. Thus, there's a must be proactive when it comes to protecting yourself from such attacks.
