There’s a new route into your company’s secure data. It’s the Blackberry PDA. A hacking program has been developed which exploits the relationship between the Blackberry itself, a company’s internal server and the network connection to which both are attached. The hacking program works because the data tunnel between the Blackberry and the server is encrypted. Intrusions can’t be detected because the protective systems, such as firewalls, exist at the perimeter of the network. This begs the question of all business owners whose employees use a Blackberry: Is your company data secure?

The hacking technique is successful because there are very few companies equipped to detect and intrusion from the inside of the network. Another reason for hacking success is the fact that companies don’t see the Blackberry as a potential attack vector. The Blackberry is not your normal handheld device. It’s a continuously running code machine that’s always on and always connected to your internal network. It has constant direct access to whatever you give it access to and most company structures allow complete access to the internal network for their employees who use Blackberries.

BBProxy is the name of the Blackberry hacking program. It can be loaded on the Blackberry either physically or via e-mail as a Trojan horse. Once loaded, the Blackberry will call back to the hacker’s system and open communication channels between the hacker and the internal network of the company. This process runs in the background behind the safety of the company’s firewall scanning for hosts with vulnerabilities in security and is generally undetected.

Recently, an ad on eBay sold a Blackberry “AS IS” for approximately $15.00. While the device didn’t come with a cable, synching station, software or manual, it did come with something far more valuable. This Blackberry came with a stockpile of corporate data all there for anyone to read as soon as the device was turned on. Many employees are insufficiently trained concerning security issues for the electronic devices they use on a daily basis.

Company data is stored as attachements on a server, rather than the Blackberry itself, so if a device is ever lost or misplaced someone could easily read sensitive documents. The Blackberry lacks encryption capabilities and relies instead on users locking the device with a password. Unfortunately, anyone with hacking abilities could discover the password and let themselves into the network.

The beauty of the Blackberry is that it’s a do it yourself type of device. It basically allows you to take your office with you wherever you go and not be caught unprepared or without the correct documents of a given meeting. However, for individuals and companies who handle and funnel much of their business dealings through these wonderfully useful devices,both internal and external server security must be taken into account.

The explosive growth and advancement of the Internet has brought many good things and services: Electronic commerce, easy access to vast stores of reference material and information, collaborative computing, e-mail, and new avenues for advertising and information distribution, online gaming, socializing sites to name a few. As with most technological advances, there is also a dark(Negative) side also: criminal hackers and Hacking. Governments, companies, and private citizens around the world are anxious to be a part of this revolution for the purpose of evolution and development, but they are afraid that some hacker will break(creep) into their Web server and replace their logo with pornography or some undesired stuff and all, read their e-mail, steal their credit card number from an on-line shopping and money transferring site, or implant software that will secretly transmit their organization’s secrets to the open Internet (spyware etc). With these concerns and others, the ethical hacker can help with the same problem. This paper describes ethical hackers: their skills, their attitudes, and how they go about helping their customers find and plug up security holes and back doors and loose points. The ethical hacking process is explained, along with many of the problems(threats) that the Global Security Analysis Lab has seen during its early years of ethical hacking for IBM clients.

The term “HACKER” has a dual usage and meaning in the computer industry today. Originally, the term was defined as:

HACKER noun :-

1. A person who enjoys learning the details of computer systems and how to stretch their capabilities—as opposed to most users of computers, who prefer to learn only the minimum amount necessary.

2. One who programs enthusiastically or who enjoys programming rather than just theorizing or mugging up the programming. These persons are the amateurs of programming who do it for self satisfaction and enjoyment rather than any professional means.

Also known as white hat hacker, an ethical hacker is an expert in anti-hacking techniques who works to prevent malicious hackers from stealing or damaging important data and ensure that computer systems and networks are safe.

Generally, these type of ethical hackers work day and night to provide security to IT systems. At times, they can even break into any other system in the course of an investigation on the ground of doubts. Both black hat hackers (also known as crackers) and white hat hackers essentially do the same thing, but an ethical hacker has altruistic motivations.

How To Become An Ethical Hacker

Earlier to become an ethical hacker there were three main ways – a history or expertise in malicious hacking, being a bright computer science graduate, and possessing a training background in systems or administration or a combination of all three.

Nowadays it has become easier for people to become an ethical hacker as there are many private institutions and colleges, who are offering full-time ethical hacking training, embedded system training network security training and many more courses.

The ethical hacking training courses have been designed on the basic principles of how to catch a thief by employing their own tricks against them. Usually, an ethical hacking training course covers the following topics, such as:



Basics of networking



 



Basics of operating systems





Basics of databases



 



Techniques of windows hacking



 



Restoration of deleted files



 



Editing of registries



 



Cracking of password



 



Counter measure of password breaking



 



Computer forensics



 



Firewalls



 



Network hacking



 



Security tools



 



Hacking tools



 



Tracking of e-mail



 



Router hacking



 



Port scanning



 



Vulnerability of windows platform



 



Viruses and their mode of spreading



After the completion of the course, one gets the opportunity to practice hacking in an ethical way to ensure the security of confidential and important data. Moreover it also instills in students a strong ethical sense of what they should and shouldn’t do as security professionals.

Major benefits of ethical hacking training course



For students, a good ethical hacking training course helps to build a successful career in many big and small IT firms or other corporate firms. The future prospect of ethical hackers is bright as more and more companies are taking all possible steps to ensure security of various data and networks.



 



A full time ethical hacking training course opens doors for those who want to build a professional career in teaching. This course will never be out of market and in future many more private institutions, colleges and universities will include the ethical hacking training course in their curriculum given the ever-burgeoning market demand for IT security professionals.



The benefits of training ethical hackers are much higher as compared to the risks associated with it. But it is essential to do the course from a reputed institution or college to get the maximum benefit.

Hacking has become a big problem concerning Internet security, one that even affects the government and other high security computer networks. Hacking attacks can range from mildly annoying or just disruptive, or they can threaten finances and even the security of people and the country. It may not be possible to completely eliminate any hacking risks, but there are steps that you can take to increase your Internet security, and minimize the risks of a hacking attack being successful. One tip is to be skeptical about what you read and see online. There are many sites or advertisements that promise you money or other benefits that sound too good to be true, and they usually are. Many times these sites will have viruses, spyware, or other malicious software programs that install on your system and make it vulnerable to hacking.

Do not open any attachments or files in your e-mail if you do not recognize the sender. Some viruses and hacking attempts use e-mail to get around your Internet security measures. A hacker may attach any type of harmful software as an attachment and then mass mail it to a large number of people. It is a good idea to use an anti-virus software program to scan attachments even from someone you know, just in case a file is infected and this fact is not known.  Having a high quality anti virus program is also essential, to ensure no viruses, worms, or Trojans are present on your system that would weaken your Internet security and make your system vulnerable to hacking.

Make sure that your system has a competent firewall installed and activated. The firewall provides a layer of Internet security to strengthen the defenses of your PC. If you have high speed Internet access, it may be advisable to unplug the Internet connection when you are not online. An open connection is seen as an invitation, and many high speed Internet providers keep your system connected and open twenty four seven. For this reason a lot of Internet access providers may offer a security program or suite that customers can use for free, to strengthen your Internet security. An efficient anti spyware program, an anti virus program, and a firewall in place will help protect you against any hacking attempts on your system.

Make sure to download and install any security updates for your system as soon as they become available. Sometimes it is possible that a software program has a glitch or two, and updates and patches are a way that these problems can be fixed. Not installing all of the recommended updates is the same as leaving your PC open for the hackers to walk through. All of these steps will help you protect your computer against any hacking attempts, and will also strengthen your Internet security so that hacking is less of a problem or risk. Use common sense and follow these simple tips, and you will greatly minimize the risk of becoming a hacking victim.
