Hack It

Friday, January 25, 2013

A number of technologies are available to companies to prevent hacking attacks. The most popular tools are Internet firewalls, anti-virus software, intrusion detection systems, and vulnerability assessment tools. Firewalls are used to set up a virtual wall between the Internet and the company's internal network to repel attackers. Anti-virus software detectsand removes computer viruses, worms, and Trojan horses. Intrusion detection systems watch over critical networks and computers looking for suspicious activities, and can alert administrators in the event of an attack. Finally, corporations use vulnerability assessment tools to inventory their computing infrastructure and better understand the existing vulnerabilities.

Contrary to popular belief, most hackers are not international or industrial spies with evil motives and a desire to rule the world; most hackers have a simpler agenda. Among hackers, one of the most frequently cited motivations is that hacking is fun and is like solving a game or a puzzle. Many hackers perceive their activities to be harmless and they do not believe that they are victimizing anyone. In addition, the thrill of doing something illegal or the ability to access data unavailable to the public can be a tempting motivator. The chance to earn recognition from within a hacker group also offers strong incentive for up-and-coming hackers who have yet to gain a reputation. Finally, many hackers justify their actions by explaining that they are doing a service for other

Enumeration - It's 4th

Enumeration.
The third phase is the process of identifying user accounts and poorly protected computing resources. During the enumeration stage, the hacker connects to computers in the target network and pokes around these systems to gain more information. While the scanning phase might be compared to a knock on the door or a turn of the doorknob to see if it is locked, enumeration could be compared to entering an office and rifling through a file cabinet or desk drawer for information. It is definitely more intrusive.
Penetration.
 
During the fourth phase, penetration, the attacker attempts to gain control of one or more systems in the target network. For example, once an attacker has acquired a list of usernames during enumeration, he can usually guess one of the users' passwords and gain more extensive access to that user's account. Alternatively, once the attacker has determined that a target computer is running an old or buggy piece of software or one that is configured improperly, the hacker may attempt to exploit known vulnerabilities with this software to gain control of the system.
Advance.
In the advance phase of hacking, the attacker leverages computers or accounts that have been compromised during penetration to launch additional attacks on the target network. For instance, the attacker can break into more sensitive administrator root accounts, install backdoors or Trojan horse programs, and install network sniffers to gather additional information (for example, passwords) from data flowing over the network.
