Hacking Mobile Phones For Identity Theft

Fifteen years ago, cell phones were so bulky and cumbersome, they had to be carried in bags or briefcases. Then they became chunky, heavy bricks. Calls dropped every other minute. Clearly, cell phones have evolved since then. Today's cell phone is a lot more than a phone. It's a computer, one that rivals many desktops and laptops being manufactured today. A cell phone can pretty much do everything a PC can do, including online shopping, banking, and merchant credit card processing.

The personal computer started out slow and stodgy, and was mainly used for things like word processing and solitaire. Today, PCs are fast, multimedia machines, capable of performing amazing tasks.

There are consequences to the rapid evolution of these technologies.

A decade ago, during the slow, dial up era, hackers (and, in the beginning, phreakers) hacked for fun and fame. Many wreaked havoc, causing problems that crippled major networks. And they did it without today's sophisticated technology.

Meanwhile, the dot-com boom and bust occurred. Then, as e-commerce picked up speed, high speed and broadband connections made it easier to shop and bank online, quickly and efficiently. Around 2003, social networking was born, in the form of online dating services and Friendster. PCs became integral to our fiscal and social lives. We funneled all our personal and financial information onto our computers, and spent more and more of our time on the Internet. And the speed of technology began to drastically outpace the speed of security. Seeing an opportunity, hackers began hacking for profit, rather than fun and fame.

Now, iPhones and other smart phones have become revolutionary computers themselves. For the next generation, the phone is replacing the PC. AT&T recently announced that they'll be upping the speed of the latest version of their 3G network, doubling download speeds. It has been reported that the next iPhone will have 32 gigabytes. That's more hard drive than my three year old laptop.

So naturally, criminal hackers are considering the possibilities offered by cell phones today, just as they were looking at computers five years ago.

Two things have changed the game: the speed and advancement of technology and spyware. Spyware was created as a legitimate technology for PCs. Spyware tracks and records social network activities, online searches, chats, instant messages, emails sent and received, websites visited, keystrokes typed and programs launched. It can be the equivalent of digital surveillance, revealing every stroke of the user's mouse and keyboard. Parents can use spyware to monitor their young children's surfing habits and employers can make sure their employees are working, as opposed to surfing for porn all day.

Criminal hackers created a cocktail of viruses and spyware, which allows for the infection and duplication of a virus that gives the criminal total, remote access to the user's data. This same technology is being introduced to cell phones as "snoopware." Legitimate uses for snoopware on phones do exist: silently recording caller information, seeing GPS positions, monitoring kids' and employees' mobile web and text messaging activities. Criminal hackers have taken the snoopware and spyware technology even further. Major technology companies agree that almost any cell phone can be hacked into and remotely controlled. Malicious software can be sent to the intended victim disguised as a picture or audio clip, and when the victim clicks on it, malware is installed.

One virus, called "Red Browser," was created specifically to infect mobile phones using Java. It can be installed directly on a phone, should physical access be obtained, or this malicious software can be disguised as a harmless download. Bluetooth infared is also a point of vulnerability. Once installed, the Red Browser virus allows the hacker to remotely control the phone and its features, such as the camera and microphone.

The Kuykendalls, of Tacoma, Washington, found that several of their phones had been hijacked in order to spy on them. They say the hacker was able to turn a compromised phone on and off, use the phone's camera to take pictures, and use the speakerphone as a bug.

If history is any indication of the future, mobile phones, just like computers, will soon be regularly hacked for financial gain. Prepare for mCrime in the form of credit card fraud, identity theft and data breaches.

Why choose iPhone as a third generation mobile?

There are number of smart phones like Blackberry Storm, LG Dare, and LG Voyager are available in the market but the main reason to choose iPhone is obviously its function , features and application that iPhone provides. The display of iPhone is not only smooth but also more responsive as compare with other mobiles. Beside this iPhone has a heat sensitive flush screen with one-touch access to apps on the iPhone with great sensor detection. The screen is also capable of rendering up to 262,144 colors and more.

The market price of iPhone is quit higher as compare with other smart phones. Beside this the iPhone has a great demand in market due to its satisfaction functionality that only iPhone can provide.

Water Jetting Technology

Jetters are mostly used for hydro cleaning. Hydrocleaning is defined as the use of water propelled at a very high speed to clean surfaces. The force generated from water jetters can remove stains, paint and dirt from walls, highways, runways and concrete.

To standardize cleaning operations and surface preparation specifications, the Steel Structures Painting Council (SSPC) has adopted the following four definitions for cleaning operations using water jetting technology:

• Low-pressure water cleaning (LP WC) - water pressure is less than 5,000 psi (34 MPa).
• High-pressure water cleaning (HP WC) is the use of water pressure between 5,000 to 10,000 psi (34 to 70 MPa) for cleaning.
• High-pressure water jetting (HP WJ) is the use of water pressure between 10,000 to 25,000 psi (70 to 170 MPa) for cleaning.
• Ultrahigh-pressure water jetting is the use of pressures above 25,000 (170 MPa) for cleaning.

Water jetting equipment should be checked before using it. Be sure that the equipment is functioning properly with no signs of wear. The area where the work should be carried out should also be checked. Check if there is a blockage on a drainage system or broken pipes. If the work is carried on a public place, be sure that people are on a safe distance.

After making all security checks and making sure it is safe to proceed, water jetter should be connected to a water supply. Choose the appropriate nozzle and make sure it is securely connected to the lance. Direct the water jetter towards the surface that needs to be cleaned or to areas that need unblocking.

It takes a lot of skill to operate this kind of equipment. Only trained workers and professional should carry out this kind of work.

Water jetters use high pressure (HP) jet equipment to clean the surfaces of:

• paving slabs
• patios
• concrete surfaces
• marble
• brickwork
• road surfaces
• walls and buildings
• vehicles

High pressure hydrocleaning equipment is also used for:

• cleaning drains and sewers
• industrial descaling and desilting
• boiler tube cleaning
• cleaning inside cooling towers
• removing water and debris from manholes
• concrete removal from bridges or road surfaces

Ultra High pressure (UHP) water jetters operate at an extremely high pressure and can be used to cut through steel. They are also used for:

• cold-cutting pipes and tank plates
• removing oil, paint and food by-product residues.
• the removal of surface coatings
• cleaning and cutting by marine chemical companies.
