Hello! Privacy is an aspect that is highly valued by Internet users. Indeed, we spend more and more time online. As a result, our private data are likely to be compromised. You may not know it, but every time you surf, you leave a trace. However, there are also ways to protect our privacy. This time we will talk about AmiUnique. A tool that allows us to know the footprint we leave when surfing the Internet. In addition, it allows you to identify the traces you leave on the Internet.

What is AmIUnique and what does it provide?

This is a service that allows us to find out how much we can be identified on the Internet. To achieve this, it is used from its web page. Once there, the fingerprints of the browser are studied. This allows developers to develop good tools. In addition, browser fingerprinting allows to collect a lot of user identification. This allows to identify the user. Let’s look at some of this data:

The type and version of browser and operating system.
Screen resolution.
Type of architecture.
Font and plug-in lists.
Microphone, camera, and more

How to identify the traces that you leave on the Internet with AmIunique

As mentioned, this tool works with the web browser’s fingerprint. To do so, it uses a cookie in the browser that remains for 4 months. Therefore, from time to time, you can re-verify the information. Accordingly, you can know if the fingerprint has become unique. To test the application, just go to this link. Consequently, you will see a screen like this.

Once there, just click on View my browser fingerprint. Consequently, we will see information like the following.

Identifying traces left on the Internet

As you can see, we will notice sensitive information about our computer. Such as the version of the web browser. In this case, Google Chrome 94. In addition to the interface language and the time zone used. It is advisable to check back from time to time to observe the evolution.

It is important to follow the evolution of these fingerprints. For this purpose, AmIunique has extensions for Chrome and Firefox. The extensions check the fingerprint every day for changes. Which can be a more convenient way to study them. At this point, it is advisable to take measures to protect our privacy on the network. Previously, we told you about the relevance of a service like Lantern, which allows you to browse privately. Okay, so we have seen how to identify the traces you leave on the Internet. See you soon!

Lenovo Shipped Laptops with a Hackable Fingerprint Manager

Biometric locking is one of the best and safest ways to secure a personal device. The most used biometric method is the fingerprint. Every single human owns a distinct and unique fingerprint. Moreover, fingerprint sensors are easier to manufacture and integrate into devices. Lenovo has also integrated fingerprint method into their laptops to ensure maximum security. However, there is a bug present in the system that needs to be fixed beforehand.

The fingerprint flaw

According to Lenovo, the Lenovo Fingerprint Manager Pro software on a number of laptop series – ThinkPad, ThinkCentre, and ThinkStation systems contain a critical local privilege escalation vulnerability (CVE-2017-3762).

The Lenovo Fingerprint Manager Pro is a sensitive software that holds the user’s biometric data and Windows login credentials. Unfortunately, the software used a weak encryption method with a weak algorithm. There’s also a hard-coded password present that all users can access. An attacker who can physically access the system can view fingerprint data and login credentials and use them for a future attack. This bug also allows bypassing fingerprint verification to steal sensitive data like Windows login information.

Affected devices

Fortunately, the vulnerability isn’t exploitable via the internet. Only others with physical access could potentially exploit the system. This vulnerability in the software affects the following Lenovo laptops. Only Windows 7, 8 & 8.1 are affected by this bug.

ThinkPad L560
ThinkPad P40 Yoga, P50s
ThinkStation E32, P300, P500, P700, P900
ThinkCentre M73, M73z, M78, M79, M83, M93, M93p, M93z
ThinkPad T440, T440p, T440s, T450, T450s, T460, T540p, T550, T560
ThinkPad Yoga 14 (20FY), Yoga 460
ThinkPad W540, W541, W550s
ThinkPad X1 Carbon (Type 20A7, 20A8), X1 Carbon (Type 20BS, 20BT)
ThinkPad X240, X240s, X250, X260

How to stay secured

This bug is reported and resolved by Lenovo. Patch for this flaw is already available. You need to update your Lenovo Fingerprint Manager Pro to v8.01.87 or higher. Download Lenovo Fingerprint Manager Pro.

Windows 10 users don’t have to worry about this bug. It’s because Windows 10 has its own fingerprint manager – Windows Hello, Microsoft’s home-baked software for fingerprint recognition.

Windows Update is also essential to keep your system secured and tight. Recently, Microsoft disabled the security patch for Spectre variant 2 on Windows systems. The patch could potentially cause more damage than the Spectre. Moreover, there has been no report of using Spectre variant 2 to exploit other systems. The patch caused more unexpected reboots and other issues. Check out more info.
