Why your Bluetooth can be Vulnerable to Hackers

“So is Bluetooth safe to use? How is Bluetooth used in hacking attacks?”



Why your Bluetooth can be Vulnerable to Hackers

With its presence in gadgets like smartphones and tablets, Bluetooth has become a widely used technology. However, while we’ve grown accustomed to using Bluetooth to connect devices to our earphones, automobiles, and other software, it still has a fair share of security flaws.

So is Bluetooth safe to use? How is Bluetooth used in hacking attacks?

The Workings of Bluetooth Security

The Bluetooth protocol has three different security models:

Non-secure mode: This mode lacks any security software. There are no measures like authentication, encryption, or communication security.

Security mode for services: Only the service level of security is present in this mode. In other words, there is no additional security provided even if an application using the secure service communicates in a relatively secure manner.

Link-level security mode: Unlike the others, this mode operates at the connection level. Here, preventing unwanted access and attempting to completely protect the system are the goals.

Each Bluetooth service has a security mode based on it that offers three levels of security. While some services may simply employ authentication, others may use both authorization and authentication. For devices employing this protocol, there are two alternative security models available.

In the Bluetooth security architecture, many security levels are also specified for both devices and services. There are two degrees of device security:

Secure: These are objects to which you have already created any kind of ongoing connection. As long as there are no restrictions at the application layer, they can use all services at any time without restriction.

Unsafe: These are gadgets that you have never connected to or communicated with before. Even if you connect to these gadgets, they are sometimes referred to as dangerous and unsafe for other reasons.

Why your Bluetooth can be Vulnerable to Hackers

With Bluetooth technology, you may transfer lots of files throughout the day. To the devices you enable to exchange files, you must, however, grant a lot of rights if you take into account the security services and modes mentioned above.

For another device to have so much control over yours merely because it is transferring a few files is a serious security concern. However, there are several safety measures you may take.

So here is how;

Only switch to “discoverable” mode when you need to use Bluetooth; keep it in “not discoverable” (transmission disabled) state otherwise.

Any Bluetooth device, including your smartphone, that is in discoverable mode is subject to Bluetooth problems. Any Bluetooth user within hearing distance of you could pick up your signal when you’re out for a walk, driving, or even just moving about your office.

Don’t keep your credit card details, social security numbers, identity information, serial numbers, passwords, or any other sensitive data on Bluetooth-enabled devices. If you’re going to use that, at least make sure to use complex passwords and additional layers of security, such Two-Factor Authentication, and keep them on sandboxed services (2FA).

How Do Cyberattackers Target Bluetooth?

When it comes to Bluetooth, there is a significant pool of attack vectors. The attacker takes control of the victim device without authorization by taking advantage of Bluetooth flaws.

After gaining access, the attacker uses privilege escalation, or utilizing a lesser exploit to gain access to a larger system, to exert control. It becomes feasible as a result to remove evidence, attack other devices, or even take control of the whole device.

From a distance, Bluetooth devices are often regarded as secure. But this is incorrect. With high-gain antennas, an assault can be launched from a distance of 1500 meters, and with Bluetooth 5, the most recent version of the technology, and evolving network topologies, it may be launched from even a greater distance.

Attackers typically use erroneous file transfers to produce unexpected outcomes. A system either enters an unstable state or crashes when an unexpected file is received and the set security level is insufficient. Attackers who take advantage of these circumstances can launch many attacks on defenseless targets.

These attacks have a long number of potential outcomes, some of which are as follows:

  • Sending SMS or phone calls.
  • Modifying or updating files while viewing them.
  • Tainting audio, video, or other types of media that could hold delicate information.
  • Theft of data or things of worth.
  • Using the device to display offensive content.

In other words, attackers can gain access to all of the functions available to you when you have root privileges. Since the main chip has no authority limitations and Bluetooth and other chips with a similar architecture are directly attached to it, this situation frequently arises.

You can prevent root privileges from being used during an attack by limiting permissions.


Why your Bluetooth can be Vulnerable to Hackers

The Blueborne Vulnerability

The September 2017 publication of the vulnerability known as Blueborne showed how dangerous Bluetooth technology may be. This hack made it possible to run programs remotely on many different devices (although remote access can be made more secure).

Compared to other attacks, Blueborne had notable distinctions. The infamous vectors need the user’s consent. In other words, the end user was giving their consent to requests for connection, device trust, and file transfers. However, in Blueborne, the user was not required to grant any rights. Remote use of it was feasible.

Bluetooth attacks are not to be taken lightly. Keep your Bluetooth connection closed at all times, and never accept connections from unknown Bluetooth devices.

Removing unwanted Bluetooth devices from the list of trusted devices and keeping your software current are important precautions. The majority of Bluetooth attacks will be thwarted by using these techniques.

Since there is no such thing as perfect security, attack methods will always change along with technology.

Microsoft mulls over the idea of Investing in Zupee



Microsoft mulls over the idea of Investing in Zupee

According to reports from people with knowledge of the situation, Microsoft has recently held discussions to invest in the Indian play-to-earn gaming platform Zupee and has offered to potentially lead a funding round of over $100 million.

This is the most recent of a series of bets the cloud services giant has made to grow its business in the important international market.

The two companies haven’t come to a deal, and the sources admonished that there is a risk the deal won’t actually happen. According to a person with knowledge of the situation, a team at Microsoft has warned the multinational computer giant against the merger due to concerns over the perception of betting.

Microsoft mulls over the idea of Investing in Zupee

Zupee choose not to respond. A request for comment made to Microsoft late last month received no response. According to two people with knowledge of the situation, the Zupee contract attempted to require the business to use Azure and other Microsoft cloud services, like many other startups, like Oyo in which Microsoft has invested in India.

The “skill-based casual gaming” platform is run by the New Delhi-based company Zupee, which has received over $120 million to far, including around $100 million in its Series B round that it closed in January of this year.

Over 70 million downloads of board games like Ludo, Snakes and Ladder, Playing Cards, and Carrom have been made by the company, which was recently valued at $600 million.

It established a relationship with Jio Platforms, India’s largest cellular operator with more than 420 million members, in January that it referred to as “first-of-its-kind strategic.”

In a previous press release, Zupee stated that the two businesses would cooperate to create a “environment that would promote faster and more efficient creation and delivery of products and services.”
