To these users, terms such as bluejacking, bluesnarfing or even bluebugging would probably be unfamiliar jargons. Ooi noted that "numerous instances of mobile viruses, worms and Trojan horses" have emerged in the past year. Bluejacking, also known as bluespamming, is a technique used to send anonymous text messages to mobile users via Bluetooth, Ooi explained.
It simply presents a message, similar to e-mail spam. The recipient can ignore the unsolicited message, read it, respond or delete it," he said. Bluesnarfing, however, is a more dangerous technique that can allow a malicious hacker to access information stored on a mobile device without its user's knowledge, said Ooi.
The Symantec executive noted that it is still possible to connect to such devices even if the users have configured their devices to be in "non-discovery" mode, where the device remains hidden when someone searches the vicinity for Bluetooth devices. A third threat, and possibly the most deadly of the three risks, is bluebugging , he said. This technique allows attackers to access mobile phone commands using Bluetooth technology, without notifying or alerting the device owner, he noted.
Bluebugging can vary from one device to another since it depends on inherent vulnerabilities. Once a connection is established, the hacker installs a backdoor or malware to bypass authentication. The malware is usually designed to gain unauthorized access by exploiting a vulnerability.
Finally, bluebugging goes beyond bluejacking and bluesnarfing, as it enables attackers to gain full control of a target device. Hackers can wirelessly interfere with a mobile phone to make and receive calls and messages on behalf of unsuspecting victims. To prevent bluebugging, Bluetooth-enabled device users must ensure proper safeguards such as:. Older devices make Bluetooth discoverable by default.
That leaves systems open to unsolicited connections. Newer computers and phones have corrected this issue. Those who use old units may need to update their software or to turn Bluetooth off. Along with the countermeasures against Bluetooth hacking, there are also other habits you should develop in order to reduce the risks of any form of Cyber Attack , including Bluetooth hacking.
Even though some precautions may, at times, seem cumbersome, they have the potential of saving you from an extremely disastrous hacking incident. Almost every part of most cities has one form or another of publicly available Wi-Fi. Often, the temptation to use these networks can be strong as they can save on mobile data costs and even offer better bandwidth at times.
However, you should not fall for it. Public Wi-Fi is not the blessing it seems to be. Many of these networks have weak security, which makes it easy for a third party to hack into connected devices. Similar to Bluetooth hacking, this can result in your personal information being stolen. Moreover, public Wi-Fi networks cannot be trusted as the administrator of the network itself may be a hacker.
This can often be the case because offering free public Wi-Fi is an easy way for hackers to find new targets and connect to devices that they otherwise would not have access to. Due to these reasons, you should only use Wi-Fi when you know that the network is administered by someone trustworthy.
This means that public Wi-Fi is generally not a good bet. Instead, when outside your home, rely on cellular data for access to the internet as this is safer.
Most modern devices offer the option of turning on a data monitor, which tracks the bandwidth being used at all times.
The amount of bandwidth being used at any given time can tell a lot about the activity of your device. For example, if you are browsing the web, you are likely to use only a few hundred kilobytes of bandwidth per second.
Conversely, if you are watching videos on Youtube, then bandwidth usage is going to be much higher. In the case of Bluetooth hacking, if the hackers try downloading information off of your phone, your bandwidth usage should shoot up. Hence, this will provide you with an early warning that something is wrong. Then you can turn your device off and get help. Generally, most software you use goes through a high degree of quality control and polish, making it extremely stable and reliable.
However, much of the software that hackers use to target devices do not go through rigorous quality control and beta testing. This can include things like randomly turning on and off, heavy stuttering, or other issues that had not been encountered before. If you notice something like this, the first thing you should do is go into the device settings and select the factory reset option.
Thanks to this, the virus or backdoor that had infiltrated your device will also be removed. Hence, this method will prevent a more serious theft of identity or sensitive information from happening. By adopting the good practices highlighted above, as well as the eight countermeasures against Bluetooth hacking, you can significantly decrease the chances of a Cyberattack catching you off guard!
Some older PCs and laptops may lack an inbuilt Bluetooth receiver. Fortunately, there is an easy fix to this problem. Bluetooth kits are essential for making your driving experience more fun yet efficient. They make your phone calls, texts, music, GPS, etc. When you use Bluetooth, you can transfer files between two devices. However, if you want to access your shared files on your device, you should know the default location for saving files.
In this article, I will give you some of the hot tips which you may adhere to so that you can master the Apple wireless phones promptly:. The more we rely on Bluetooth in our daily lives, the more vulnerable our personal data becomes. Like with all technology, hackers are waiting to get their hands on your data.
Skip to content Despite all the benefits of Bluetooth, the technology can still be risky to use from a cybersecurity perspective. Quick Navigation! However, these attacks are rarer, so you're limiting hackers' options. Do not accept pairing requests unless you are sure it's with a device you want to link to.
This is how hackers gain access to the information in your device. Crowded public places are hotspots for hackers. If you must pair a device for the first time, make sure you do it at home, in the office, or in a secure area. If a Bluetooth device that you have previously paired with gets lost or stolen, make sure you remove it from your list of paired devices. In fact, you should do this with all the Bluetooth devices this stolen or lost gadget was previously connected to.
Gadgets are often rolled out with unknown vulnerabilities. These will only be discovered once buyers start using them. This is why companies release patches and critical updates for software. Updates repair security flaws that have recently been discovered and fix bugs. Installing them helps keep hackers out. Yes Bluetooth hacking can cause a lot of damage, but you can take steps to prevent it. Using this technology comes with a lot of security and privacy risks.
