More precisely, researchers found 146 vulnerabilities in mobile devices from 26 different manufacturers. Most manufacturers supply products to the Asian market, but among them there are also global brands such as Samsung and Asus.^[1]

Unreliable storage of cryptographic keys

On February 25, 2022, it became known that the Galaxy S8, Galaxy S9, Galaxy S10, Galaxy S20 and Galaxy S21 phones unreliably store cryptographic keys. Get the details.

2019

Any fingerprint in the Galaxy S10 can be hacked

In mid-October 2019, Samsung recognized a serious vulnerability in the security system of its devices, which allows anyone to hack into a Galaxy S10 or Galaxy Note 10 smartphone using a fingerprint. The company said it is already working on a software fix.

Samsung recognized the problem of unlocking the Galaxy S10 as someone else's imprint

In recent years, methods biometric authentications such as fingerprints have become increasingly popular - they are often considered easier to use or safer than traditional passwords. The latest Samsung option for smartphones the S10 and Note 10 allowed users to scan their fingerprint directly from the screen without touching a special sensor. However, a serious mistake crept into the software.

According to the BBC, this malfunction was first discovered by a couple from the UK - it turned out that the husband can unlock his wife's phone using his fingerprint. Given that Samsung's fingerprint identification system allows users not only to unlock the smartphone, but also to make various payments through applications, this vulnerability poses a serious security threat.

Many hope that this incident will focus the attention of users and manufacturers on another serious problem of Samsung: the company often launches products on the market until the completion of full testing. One way or another, a statement from Samsung says that a software update will soon be released that will correct this malfunction.

We are studying this problem and will soon provide users with a software patch, "said a representative of Samsung. - We encourage all customers who have questions or need help downloading the latest software to contact us via the hotline.[2]

The regulator sued Samsung for lying about the water resistance of the Galaxy S10

On July 4, 2019, the Australian Competition and Consumer Protection Commission (ACCC) sued Samsung, accusing the South Korean corporation of providing inaccurate information about the functionality of its devices.

The lawsuit says that in its advertisement, Samsung shows the immersion of smartphones in the pool and sea, after which the tube continues to work. However, the manufacturer did not know or did not conduct sufficient testing regarding the consequences of such contact with water.

The regulator convicted Samsung of cheating: the Galaxy S10 is not so water-resistant

The antimonopoly regulator claims that some users allegedly have Samsung moisture-proof smartphones that failed after getting into the water, and the company refused to repair them under warranty.

Obviously, the use of Galaxy phones in the water can damage them, since the official Samsung website explicitly states that the Galaxy S10 phones are not recommended to be used on the beach or in the pool, and the company rejected claims for warranty repairs from consumers whose phones were damaged when used in the water, the regulatory agency said in a statement.

Reuters calls the ACCC lawsuit the first of its kind and notes that it could lead to a multimillion-dollar fine. The complaint cites 300 advertisements in which Samsung declares the water resistance of its equipment in the ocean and at the bottom of the basin.

Samsung's statements about waterproofness were carefully studied back in 2016, when the American magazine Consumer Reports reported that the Galaxy S7 phone, which is immersed in the aquarium in advertising, was not tested with water. Then the manufacturer assured that the problem affected a small number of devices, and it was fixed. However, consumer complaints about tubes that broke after contact with water continued to appear on forums and social networks.^[3]

5G Launch and First Challenges

On April 5, 2019, sales began on the first commercial smartphone on the market with support for fifth-generation (5G) networks - Samsung Galaxy S10 5G. A week later, it became clear that the device has problems with high-speed Internet.

The Galaxy S10 5G received separate antennas for 5G and LTE, which are simultaneously connected to networks to provide Internet access at speeds of up to 2.7 Gb/s. However, the first buyers of the product claim that their phones cannot reconnect to 5G after losing the connection, as a result of which the speed of web surfing drops.

Samsung began selling the world's first 5G smartphone. Owners complain about slow Internet

The owners of gadgets have nothing left but to reload the device, and repeatedly. The problem is observed in all major South Korean operators, including KT Corporation, SK Telecom and LG U +.

As the portal SamMobile notes, there are several reasons why the antenna can break the connection with the 5G network. One is that the handset begins to transmit data between two cell towers, one of which must delegate the connection to the other. Another scenario is that the device simply refuses to connect to a high-speed 5G network due to a weak signal.

One of the experts in the telecommunications market in a conversation with Business Korea said that the problem lies not in the number of 5G base stations, but in the fact that operators have not optimized their networks for a smooth switch between 4G and 5G.

The problem is similar to when a smartphone goes from a 4G connection to a 3G connection when used in areas where there is no suitable cellular equipment.

Samsung has released several software updates for the Galaxy S10 5G that should eliminate the flaw before the smartphone enters the international arena. Its sales in the American market will start in mid-May 2019.^[4]

Hacking a fingerprint scanner

In early April 2019, a Samsung Galaxy S10 user demonstrated a way to quickly hack a flagship smartphone. This will require image editing software and a 3D printer.

A video and a description of the method are posted on the Imgur portal. The user under the nickname darkshark took a photo of his fingerprint from a glass, edited it in Photoshop, and then in 3DS Max, highlighting the picture of the print. Then he uploaded the photo to the 3D printing program AnyCubic Photon LCD and printed a plastic copy of the print. All this allegedly took only 13 minutes.

Samsung Galaxy S10 hacked in 13 minutes with Photoshop and 3D printer

Samsung Galaxy S10 is equipped with a fingerprint scanner that is built into the screen. Unlike most other smartphones, Samsung's flagships use not an optical, but an ultrasonic sensor, which, according to the developers, is faster and safer.

However, as darkshark showed, such a sensor can be deceived. The user managed to hack the phone from the third time. He noted that the problem is that payment and banking applications, including Apple Pay, are increasingly using fingerprint-based authentication to unlock. Therefore, to access the phone, you only need a photo with a fingerprint, public programs and access to a 3D printer.

I can complete this whole process in less than 3 minutes and remotely start 3D printing so that this is done by the time I come to it, "the hacker wrote.

According to the user, who commented on the darkshark manipulation, you can unlock the Samsung smartphone even by printing a photo of a fingerprint in high resolution. The Verge emphasizes that fingerprints can be forged on the most modern smartphones.^[5]

Three ways to deceive the device unlock function by face

March 11, 2019 it became known that deceive the function of unlocking the device in the face in the Galaxy S10 + you can even use YouTube videos.

The facial unlocking features implemented in Android devices are already considered unreliable and are criticized everywhere. However, Samsung somehow managed to bring the inefficiency of the facial recognition system to the next level. As of March 12, 2019, at least three effective ways are circulating on the Internet, allowing you to deceive the Galaxy S10 + and unlock someone else's device.

First, the Galaxy S10 + cannot distinguish a living person from a photo. In order to unlock someone else's device, it is not even necessary to have a picture of its owner printed on paper, it is enough only to show the Galaxy S10 + photo on the screen of another smartphone.

Secondly, you can unlock the device by simply lifting it to the screen from a YouTube video on which its owner is captured. Using this method, the Unbox Therapy team was able to unlock the Galaxy S10 + in three out of three cases.

Thirdly, the device is not able to distinguish relatives with similar facial features. Moreover, the Galaxy S10 + can easily accept a brother as a sister and vice versa.

When activating Face Unlock, the manufacturer warns that the function is provided solely for the convenience of users, and not for security. However, given the cost of the Galaxy S10 +, users will have to put a lot of money for convenience without^[6].
