Most PCs, aside from some newer laptops, do not come with built-in Bluetooth. Some of these devices are low-power Class 2 devices, transmitting up to 10 feet, while other Class 1 devices have extendable antennas and claim to cover upwards of feet.
Windows requires drivers to operate with your Bluetooth device. Windows XPcomes with built-in Bluetooth driver support, and if your USB device is recognized when you insert it, we recommend that you use the Microsoft drivers [Hack 2].
In our examples, we were not able to get our USB Bluetooth adapter to work with the third-party drivers that shipped with the unit. Uninstalling those drivers and allowing the Microsoft drivers to detect the device resolved the issues.
If you are in doubt about the capabilities of your Bluetooth phone, check that site for more information on device support.
Setup and capabilities in these programs vary from phone to phone, so be sure to check to see if your phone is supported. In addition to a Bluetooth adapter, PuppetMaster requires Windows or XP and one of the following mobile devices with Bluetooth onboard:.
Installation of the software is simple. Accept all of the defaults. Once PuppetMaster has been installed, run it from the Start Menu. A circular icon will appear in the taskbar, indicating the program has loaded, and you should see the status window shown in Figure If you are using non-Microsoft Bluetooth drivers, you might need to pair your phone with your PC ahead of time.
Instead, we selected the Preferences button in the dialog to open the PuppetMaster Preferences window, as shown in Figure At this point, enable Bluetooth on your phone to make it discoverable.
In either case, you will be presented with a list of appropriate device connections that PuppetMaster found Figure Choose your phone from the list and click Add.
Confirm the choice to add your phone to PuppetMaster. To complete the setup, click Connect in the Preferences dialog. Now that you are connected, you can control many aspects of your PC directly from your phone.
As shown in Figure , you can add menu categories in PuppetMaster, and then add items to those categories to expand your control options.
Most importantly for presentations is the ability to control PowerPoint. You can perform system commands such as shutting down, activating the screensaver, or browsing files.
Another great function for presentations is Mouse Mode. On phones that have a directional control, such as the T, you can direct the mouse cursor remotely.
One final set of abilities that PuppetMaster gives you is Events. As shown in Figure , you can set up special events to occur when the phone comes in range of the PC, when it leaves range, or when you get a call.
Events are handy if you are using your phone as a media controller. You can have iTunes pause the currently playing track when your phone rings, so you can hear your caller.
If your phone goes out of range of the PC, you can make it assume that you have left and activate your screensaver, set your status to Away in your IM program, and mute the speakers.
While it does allow you to control your PC remotely from your Bluetooth phone, it also is a complete synchronization utility, allowing you to edit your phone contacts; store, sort, and send text SMS messages; and much more.
Many other phones have been tested, but there is no central list of known working phones. You will need to search for your phone by clicking the Tested Devices link on the FMA web site, which will take you to a SourceForge bug reports page.
The program is also somewhat different from PuppetMaster in that, in addition to Bluetooth, it also supports infrared and serial phone connections.
For serial support, you can use Windows 98 or greater; infrared requires Windows or greater, and Bluetooth is supported on Windows XP only.
Bluetooth requirements are the same as for PuppetMaster. FMA supports both native Microsoft Bluetooth drivers and third-party drivers.
FMA can talk to your phone in several ways. As shown in Figure , you can tell FMA which COM port has been mapped to the phone; you can specify the MAC address of your phone for the Native Bluetooth drivers; and you can also use infrared if your phone supports it.
The first is the selection of components, shown in Figure If you opt to not install the Microsoft Components, FMA will not work correctly until it is reinstalled with the components.
Secondly, you can customize the installation as usual by choosing where icons are created, as shown in Figure You need to make sure to include at least the two top Microsoft components; otherwise, FMA will not function.
It would be nice if there were documentation to cover this with the package. Once the program completes installation, it will launch automatically.
A phone icon will appear in your taskbar, showing that the program is running. The main screen of FMA, shown in Figure , should give you a pretty good idea of what the program is capable of.
FMA gives you complete control over your text messaging. The New Message window is shown in Figure You can also view new messages in your Inbox, organize them in the default folders shown, or create new folders to categorize your messages.
The program also gives you control over your contacts, both in phone and SIM memory. As shown in Figure , FMA lets you assign custom icons to a contact, and give them a custom ringtone.
You can also set the preferred number for the calling contact, as well as associate each contact with a specific contact in Outlook.
When a new call arrives, you will get a Caller ID pop-up window on your screen, as shown in Figure If you have a headset connected to the PC, and the correct Bluetooth Audio settings turned on, you can use your headset to answer and receive calls.
You have complete call logs of all incoming, outgoing, and missed calls. This can be a real lifesaver when you know that you called a client 37 days ago and left a message, but they tell you no one ever called them.
Print out the log and send it to them as proof! You can also browse the files on your phone. Tired of those hideous background pictures that come by default?
Delete them. Sick of those horrible MIDI files that you get for ringtones? Delete them! Even better, replace them with custom pictures and MIDI files.
There are millions of MIDI files available for free online. You can really manage all aspects of your phone from FMA.
It will even let you power off the phone or lock the keypad of the phone from your PC. Lastly, you can control your PC. There are also controls for PowerPoint and two mouse modes to control the PC mouse from the joystick or keypad.
FMA also provides a General Tools menu on your phone that allows you to turn the PC display on and off, lock the display, start the screensaver, and log off the current user, as well as hibernate, shutdown, and restart.
FMA does have scripting support from the Microsoft Script tools that it downloaded during installation.
Have you ever wanted to do something on your computer from across the room? How about from the other side of the world? It can be useful to be able to access your desktop machine remotely.
You could check server logs, restart failed services, or even post to your weblog. If you have a home network, you can set up all of your computers so that they are accessible remotely.
Virtual Network Computing VNC is an open source application that is designed to allow one machine to control another machine over a network.
It was originally developed at Bell Labs. VNC is also useful for collaboration. Multiple viewers clients can connect to the same server.
Each viewer has its own cursor. You can use these cursors to point to content on the remote machine. The viewers display the cursors for all of the other viewers as well.
Each cursor is displayed differently from the others so you can tell them apart. The server side comes in Windows, Mac, and Linux flavors.
There are other versions of VNC available as well. You will also need an application to access the server. In typical computer-speak, this application would be called the client , but VNC uses the term viewer instead.
For example, their SlideShow Commander is a specialized application for remotely controlling PowerPoint Presentations. To access your desktop remotely, you need to know its external IP address.
All you have to do is look up your IP address in the appropriate place and write it down for use in setting up PalmVNC.
If you have a dynamic IP address e. An IP publishing service will typically let you choose a hostname within their domain. You end up with a name like hostname.
Keep this symbolic address handy for setting up PalmVNC. An IP address uniquely identifies any computer on the Internet. It is used for routing sessions to the appropriate machines.
An IP address is a four-part number. Each part is a number in the range 0— The numbers are separated by decimal points. Thus, an IP address can look like Most people at least at home have dynamic addresses.
A dynamic address is assigned by the ISP on a periodic basis. To connect to a computer over the Internet, you either need to know its IP address, or you need to have a name for it e.
If you have a dynamic IP address, you can hook up with a free service to publish the address. You get to choose a hostname for your computer within the domain names offered by your service.
Then you can refer to your computer via hostname. Some service providers are No-IP. Download and install the appropriate version of VNC on your desktop machine.
After VNC has finished installing, run the configuration part of it. You will be able to choose a password for VNC, as shown in Figure Choose a good password at least eight characters and a mixture of upper and lowercase characters, numbers, and punctuation.
This password is all that is needed to access your machine over the Internet, so choose carefully.
Either write it down or remember it; you will need the password when configuring PalmVNC. When you run OSXvnc, you will see a screen similar to Figure Select a display number usually 1 and port usually Set a password; this is the password you will use when you log in from PalmVNC.
When everything is working and you are connected, you should see a screen on your Palm device that looks like Figure You will need to open some ports in your firewall for VNC, and VNC itself needs access to ports on your computer.
By default, VNC sends information including passwords as plaintext. You will need to open port 22 in your firewall for SSH, if you have not already done so.
For other VNC servers, the process is fairly simple. From the client side of a desktop machine, you want to run something similar to the following:.
Whenever VNC is running, it will look for incoming connections. If you have a personal firewall e. By default, VNC uses ports and port is only used for a Java-based viewer , but you can change those ports under the Connections tab.
You can create multiple VPN accounts for connecting to different machines. Set the account name in the Account edit box. Note that this name is only used to distinguish between different setups in Mergic.
You can also choose to have Mergic VPN autoconnect to the server when specific applications are run. Start by creating a new network connection from the Network Connections section of the Control Panel.
Select an Advanced Connection, as shown in Figure The next dialog box lets you select the advanced connection options. Select Accept incoming connections, as shown in Figure Next, choose the device that you want to allow VPN connections from.
Then, you will need to allow VPN connections in the dialog box shown in Figure After that, select the users that you want to allow to use VPN.
You will need one of these usernames and the corresponding password when you set up Mergic VPN. Unzip it and install palmvnc.
Set up a new connection to your desktop machine, as shown in Figure Enter the IP address for your desktop machine and the password you used when setting up the VNC server, and then tap OK and Connect from the next form.
If everything is working, you should now see your desktop on your Palm device. You can move around the desktop by using the narrow scrollbars on the right and bottom of the screen.
At scaling, you can view a x desktop on a x Palm device or even up to a x desktop on a x Palm device.
No matter which operating system your desktop is running, you can still control it with PalmVNC and an appropriate server. Make sure that you use an appropriate level of security for the environment you are in running over a local network or running over the Internet.
Your Palm can take the place of all of them. You need software to convert your Palm into an infrared IR remote. You should look at the home theater devices that these two programs support and pick the one that is compatible with your gear.
If neither program covers all of your devices, then you have a couple of choices. If you have the remotes for your devices, and you are looking at simplifying down to just your PDA, then you can switch the applications into learning mode.
Line up the remote and your Palm device on a flat surface with the IR end of the remote pointed at the IR port on your PDA and run through all of the important buttons on the remote.
Save the buttons for each device under a unique name. If you are missing some of the remotes, then you can try to find an IR code library on the Web.
Once you have all the codes for the devices you want to control, it is time to create button layouts. There are a variety of interesting button layouts on the Web.
The web sites for the IR software have some button layouts, as does RemoteCentral. You can look at these for inspiration. You should keep in mind what you want to do with each button layout that you create.
For example, a common layout is watching DVDs. You could combine these actions into a macro, then have a single Power button that turns everything on.
You might also need volume, play, pause, stop, fast forward, rewind, menu, and arrow keys. A button layout for watching TV might include a number pad, and channel-up and channel-down buttons.
Fortunately both companies also provide hardware versions of their products. You will need to find a used Visor. The Visors have a Springboard slot in the top that can take plug-in modules.
All you have to do is stick the OmniRemote module into the Visor. The software is pre-loaded on the module. NoviiRemote makes a product called the NoviiRemote Blaster.
This is an SD card that functions similarly to the OmniRemote product, except that it works with SD-compatible devices such as recent Palm-branded devices.
Make sure that the software or hardware that you want to use is compatible with your PDA. If not, consider buying a cheap Palm to use as a dedicated remote control.
Even if you plan on buying a hardware device to install in your PDA, start by downloading the corresponding trial software—you need the software to check that it can control your device.
You can easily switch between different devices, as shown in Figure Use the trial version of NoviiRemote to make sure that the controls work. Start with the default codebases collections of remote control codes that came with the software.
For each device you want to control, try out the included codes to see if the functions you want to use work. Download these and try again.
OmniRemote, shown in Figure , provides macros in addition to the standard buttons. A macro can combine multiple actions e. OmniRemote supports a different set of devices natively than NoviiRemote.
Use the trial version of OmniRemote to make sure that it can control your devices. You need to either program all of the buttons yourself if you have the corresponding remote controls , or you can try to find codes on the Web.
This program is called CCF Converter, and it converts remote control libraries from. CCF format to the internal format that OmniRemote uses.
These databases are the. CCF files that you can convert. If you find files that seem to match your home theater devices, then download them.
You will need to unzip the files as well. Run CCFCnvt. You will see a screen similar to Figure For each file, look for the device that you want many of the CCFs are for a set of devices so you may need to experiment to figure out which file corresponds to the device you want.
When you have collected all of your devices, then select Create PDB File to generate a new database with your devices in it. One of the nice features of OmniRemote is that you can create macros.
To create a macro, start by creating a new button and select Macro as the type of button. Then click on the Edit Macro button and hit Insert. You will be prompted to tap buttons to add them to the macro.
Either of these devices can simplify your remote controls. You will end up with a single Palm device instead of a stack of remotes.
You also have the ability to create sophisticated macros to handle multiple common chores at once. You can see an example of creating a macro to turn on the TV, increase the volume, and switch to channel 25 in Figure Macros can give you a lot of power in a single button.
With a few macro buttons on a single page, you can easily perform a number of functions. Will you send and receive email on the phone?
Do you plan to send a lot of camera phone pictures or video clips? How about posting to your weblog [Hack 18]? And most important, will you use your phone to connect tether your laptop to the Internet [Hack 4]?
We will use the word tether even when referring to wireless methods of using your handset, such as the Bluetooth connection. Data plans come in two flavors: metered and unlimited.
With a metered plan, you get anywhere between 1 and 20 MB per month as a base allotment, and if you go over, you pay by the kilobyte.
There are two types of unlimited plans: handset plans and really, honest, we-mean-it unlimited plans that let you use your phone as a wireless modem for your laptop or PDA.
The underlying wireless network technology is known as the data bearer of the mobile data. The GSM network provides data access over the phone data calls.
It works in the same way as the dial-up modem on a PC. The benefit of this technology is that it is available everywhere you can get coverage.
However, the drawbacks are the slow data rate between 9. Since the call must be connected for the entire data session, it counts against your airtime minutes.
If you want to make a voice call, you must first disconnect the data call. GSM data is known as 2G second generation.
The GPRS network allows the phone to have direct access to the packet-switched data from the network. The phone does not need to dial any calls.
This feature allows the phone to have always-on access to data without using up airtime minutes. GPRS is known as 2.
The data speed of 2. The EDGE network coverage is still limited. Only a handful of devices released since support the EDGE data bearer.
It offers broadband data speeds of around Kbps. However, UMTS coverage is very limited. In the States, it is currently available in only a few selected cities.
In addition, UMTS service plans can be very expensive. Which data bearer is available to you depends on your wireless operator, your location, and your service plan.
If your current service plan does not include any data service, you can call up your wireless operator and add it for an extra monthly fee.
The data service is typically metered by the bandwidth you use in a billing period. This could be the hard part, but the good news is that you can just take a best guess.
Here are some considerations:. As such, you could get away with a metered data plan. If you plan to connect your laptop to your cell phone to get online, welcome to what some folks think is a gray area.
However, anecdotes abound concerning people who claim to have received nastygrams from their cellular operator after using large amounts of data in this way.
For example, every web browser transmits a User-Agent identifier every time you load a page; this is a dead giveaway.
Some providers will bill you differently based on your usage. All those guidelines aside, the best thing to do is choose an unlimited data plan, if one is available otherwise, pick the most generous metered plan.
If you plan to use your phone as a wireless modem for your laptop, you should definitely choose an unlimited plan that supports tethering.
Table shows a few unlimited data plans that were current as of this writing. If you think Table looks very U. In other parts of the world, metered data plans are more common.
And the States has its share of those as well. Table shows some of these plans, from the low-end to the high-end offerings, and includes the range of charges you can expect if you go over the metered limit.
However, most providers will let you add or change your data plan at any time. But before you make a change, ask the all-important questions: will this require me to agree to a contract extension, and will I be charged a termination or activation fee to make this kind of change?
One problem you might run into is a customer service rep that is unfamiliar with the plan you want. The best thing you can do is make sure you know the name of the service.
The data plans available to you might depend on what level of voice service you have. Although most providers will prorate the new plan after you change it, make sure you understand what exceptions are in place between the date you change the plan and the date your billing cycle resets.
For example, suppose your billing cycle ends on the 28th of each month, and you are just shy of the 20MB limit on a metered plan when you switch to an unlimited plan on the 23rd of the month.
You might think that you can use as much data as you want between the 23rd and 28th, but be sure to ask—when it comes to cellular billing, nothing is as simple as it appears.
Use a mobile blogging service to post blog entries with pictures from your mobile phone. Not long ago, bloggers could only update their blogs using a computer.
Inspiration, however, does not always coincide with the presence of a bulky computer. At the turn of the century, some adventurous and creative bloggers started blogging from their mobile devices.
The word moblog was thus coined, referring to blogging from a mobile device mobile phones, PDAs, etc. If blogging without a computer is convenient, moblogging with a camera phone is exciting.
In just a few clicks you can snap a quick shot and add a few punch lines, and minutes later the neatly formatted post on your personal blog can be shared with the entire world!
The dry spell between November and March? There are two major approaches to moblogging, regardless of the myriad phone models and their different capabilities: SMS moblogging and email moblogging.
This hack introduces and compares these two methods, with an emphasis on the latter. Instead of email, you can also use MMS to post blog entries from your camera phone.
SMS moblogging works on any handset that can send SMS, which is virtually every mobile phone nowadays.
You write the blog entry on the mobile phone and send it via SMS to a service phone number provided by a moblog service. The moblog service interprets the received SMS message and posts it to your blog.
Txtsolutions can host your blog on its own site, or post your blog entries to your account in a list of supported third-party blog hosts.
If the SMS moblog service posts the blog entries to a third-party blog host on your behalf, it needs to know your login information on that third-party site.
Despite the meager prerequisite of the handset, SMS moblogging has some major drawbacks. First is the nagging character limitation for SMS.
Second, even if you are laconic enough to squeeze each of your posts into fewer than characters not words , SMS moblogging is text-only. Third, you need to pay extra to the SMS moblog service provider.
There are other devices designed to lock or unlock automatically. Clearly, there are real risks with Bluetooth. In general, for a hacker to be successful, he has to be within feet of you for a Class 1 Bluetooth device or 30 feet for Class 2.
Bluejacking a device taking control to send messages to other nearby Bluetooth devices , Bluesnarfing accessing or stealing data on a Bluetooth device , and Bluebugging taking total control of a Bluetooth device all require different exploits and skillsets.
There are far easier ways to accomplish the same things. First and foremost, disable smart lock features on your phone and PC.
And only use devices that have authentication for pairing. If you purchase a device that requires no passcode—or the passcode is —return it for a more secure product.
That just adds another attack vector that hackers could use. The Best Tech Newsletter Anywhere. Join , subscribers and get a daily digest of news, comics, trivia, reviews, and more.

In other words, this approach is too specific. Instead, experts propose to design a method of analyzing processes related to the execution of any AT command to detect any possible anomalous activity that may become an exploitable vulnerability.
These are code snippets used to control some tasks related to cellular network usage. A basic set of commands was established as a standard in the mobile communications industry; on the other hand, smartphone manufacturers include their own AT commands to run multiple functions.
It is required to pair the peripheral device speakers, headsets, etc. The AT commands is then sent to the Bluetooth component at the application level, where the action related to the sent command is completed.
Not all of these commands are processed or recognized by all smartphones, as this depends on the manufacturers. ATFuzzer, the analysis method developed by the researchers, consists of two modules: evolution module and evaluation module, which interact in a closed way.
The evolution module starts with an initial AT command grammar that mutates to generate Psize refers to population size, a parameter for ATFuzzer , different versions of that grammar.
Specifically, ATFuzzer generates new grammars from the main grammar through the following high-level operations:. To assess the effectiveness and scope of this approach, 10 different models of Android operating system smartphones from six different manufacturers were analyzed.
Today i am sharing very interesting trick that how to hack Bluetooth Hacker well you all are familiar with a term of hacking and now a days the people who are unaware of hacking losses their important data, credit card numbers and lots of other things which are valueable.
Well today I am sharing an interesting piece of hacking. People are amazed when they see hacker access a mobile phone with the android bluetooth hacker and multimedia phones.
But let me tell you its very simple. There are various bluetooth hacker apps and lot of software already available on the different website which helps hackers to hack any cell phone and multimedia phones.
Press the SCAN button 2. Wait for all phones in range to appear 3. Moffitt describes a cloud-connected smart toy he once evaluated that could play audio messages stored in the cloud.
Unfortunately, you could also connect to the toy via Bluetooth. It used no authentication whatsoever, so a malicious actor could stand outside and record anything to it.
Moffitt sees the price-sensitive device market as a problem. There is often zero security vetting going into the design of these products.
The attractive nuisance doctrine is an aspect of tort law. Some Bluetooth features are like an attractive nuisance that put your device and data at risk, and no hacking is required.
For example, many phones have a smart lock feature. So, if you wear Bluetooth headphones, your phone remains unlocked as long as you have them on.
While this is convenient, it makes you vulnerable to hacking. It locks your computer when your phone goes out of Bluetooth range.
And even then, Dynamic Lock is sometimes sluggish. There are other devices designed to lock or unlock automatically. Clearly, there are real risks with Bluetooth.
While doing field work, you sometimes wonder if you should even bother getting out your laptop and setting up your dongles. Sometimes it helps to have a quick way to look at the traffic, and it is even better if it returns useful information - saving you time with what to focus on once you get the laptop out.
There are a number of free applications for your phone that will help with this. Some of the free apps have mixed results, but a basic guideline for choosing one is to select them by the developer.
There are a number of companies that sell tools for building various applications or IoT devices or both that write decent free Bluetooth apps for testing from your phone.
These are usually fairly high quality because they are intended to complement your development process while using their purchased products.
Figure 7. From the above, you can see it is useful in finding unusual items. This was captured mid-flight during a business trip.
Figure 8. Excellent app with decent logging capabilities. Most of the hardware and even some of the software comes with Wireshark plugins compile and install all of them.
While there are too many to name and plan for, there are some general rules to keep in mind. Read the documentation, but note the date.
If the instructions are old and refer to an old version of Wireshark, it is possible that the plugin comes included with the newer version of Wireshark.
Most plugins will compile without incident with a newer version of Wireshark. In fact, most will compile with the Wireshark development package for your Linux version, for example, wireshark-dev on Ubuntu.
The purpose of the plugins is simply to interpret the raw Bluetooth packets inside the Wireshark app into something a little more readable, and since there are multiple protocols involved with Bluetooth, it helps to make some sense out of what is going on.
There are often a couple of different ways to sniff Bluetooth - directly within Wireshark and with one of the command line tools itself.
For example, Ubertooth includes the aforementioned ubertooth-btle, which allows capturing of Bluetooth traffic and saving the data in pcap format that Wireshark can read and interpret with the appropriate plugins.
And you can use more than one Bluetooth source during sniffing within Wireshark. If you are using one dongle to probe a device and another trying to flood it at the same time, you can see the results from both in the same sniffer session.
And it helps when testing how one dongle or CLI performs against the other. This also involves simply documenting what the device does during various stages.
For example, can more than one device pair to it? Does it begin advertising itself immediately after applying power for the first time, or do you have to perform an action such as a button press before it will allow pairing?
Does it cycle through periods of advertising versus not advertising, perhaps in an effort to conserve battery power?
But even more importantly, seeing how much information can be read remotely to fingerprint or otherwise determine information about the device - particularly as the state of the device changes.
And this gets into the second area. Things such as the name of the device or a model number can come in handy. Often when fingerprinting a device, you find information that will assist your IoT investigation in other areas - such as Bluetooth chipset and perhaps firmware versions associated with that chipset.
Being able to remotely determine the firmware version down to the exact build version can be a massive timesaver - particularly if you are able to find firmware versions online.
With a little Googling, determining the Bluegiga chipset and the build version of 71 helped determine the exact firmware version from Even poking around with freeware apps on a phone can reveal interesting info:.
Figure 9. In the above example, the model number string of BLE coupled with the hcitool output with Bluegiga and the build version helped confirm the exact firmware.
For the record, using the command line tool gatttool one could also determine the exact same information, although not presented nearly as cleanly.
The character properties values are interesting - for example, 02 is read only char properties: 0x02 , and 0a is writable. Finding all of the interfaces that allow for the external writing of values is an important part of examining the attack surface, and having all of the UUID values are great for when it comes to grepping through decompiled code.
This allows you to potentially map values that are inputted into the IoT device and see how these values are processed by, for example, the accompanied app on the phone.
