The Qualcomm Snapdragon 8 Gen 1 processor has received support for the smartphone’s always-on camera.
“Your phone’s camera always looks for your face safely, even when you don’t touch your phone or pick it up to wake it up.” With these words, the VP of Product Management at Qualcomm Technologies Judd Heap Judd Heape introduced the new feature of the Snapdragon 8 Gen 1 processor, which supports the always-on camera. This processor should hit high-end Android smartphones early next year.
How you react to Heep’s words depends on how you look at them. From Qualcomm’s point of view, the new functionality will make life easier for users, as they can wake and unlock their smartphones just by looking at them, without having to pick them up. During the presentation, Qualcomm presented cooking as an example, when you need to check the recipe on the phone screen, and your hands are busy.
According to the company, the new feature will help secure the device, as it will be blocked if it ceases to see the owner’s face or detects that someone is looking over his shoulder. The feature will also be able to block the display of personal information or notifications if the user is looking at the phone with someone else. Simply put, if the user does not look at the phone, it remains locked, and if the smartphone sees the user, it will be unlocked. If the smartphone sees the user and someone else, it will automatically lock itself or hide personal information and notifications from the screen.
However, from a privacy standpoint, an always-on camera is a real nightmare.
Similar functions are already used in smart home devices. For example, GoogleNest Hub Max uses a camera to recognize its owner’s face when he appears nearby, in order to give him useful information (for example, a calendar). Home security cameras and smart door locks are also constantly on, recording activity or even some faces. However, these devices are only used in the home, and unlike phones, users do not carry them around with them. In addition, they often provide the ability to turn off the camera or tracking mode when the user is at home. It is unlikely that smartphone manufacturers are implementing anything like this in their flagship products.
Recently, there have been increasing reports of data leaks or social engineering techniques used to turn on smart cameras when they should be turned off and send video from them to remote servers, all without the user’s knowledge. Modern mobile operating systems warn the user when an app gains access to a camera or microphone, but whether they will be able to warn when malware connects to an always-on camera is unknown.
Can Microsoft Defender antivirus be disabled in Windows 11?
microsoft defender has reached a spectacular level of maturing with windows 10. What started as a basic malware protection more serious, it has become one of the best antiviruses on the market, with the advantage that it is free, lightweight, and is already included and activated with the operating system. However, there are times that we may be interested in deactivating it, but is it possible to do it with Windows 11?
When we install a third-party antivirus, Microsoft Defender is disabled. However, there may be times when it is not deactivated properly, or there may be times when we simply want to temporarily disable the antivirus to install something that is detected as a false positive. It is also possible that, on a weak computer, Microsoft Defender consumes a lot of resources; especially when booting the system. There are lighter options, or if we don’t have the internet connected device, we may not even need the antivirus.
Windows 11 allows you to disable antivirus
In the Security section of Windows 11, luckily, we can disable many antivirus functions, including Real-time Protection, which is the one that usually causes problems when it comes to detecting false positives in files that we know are safe. This protection can only temporarily deactivate, but the rest of the protection modules can be permanently disabled.
So, effectively, we can temporarily disable the protection in Windows. To do this, we go to Settings in Windows 11, and there we enter the Privacy security tab. In there, let’s windows security. Once there, click on the option that says Antivirus and threat protection. In there, we just have to go to the part of managing the configuration of Real-time protection, and disable it.
It can also be permanently disabled
This deactivation is temporary, so if we want to deactivate it completely, we will have to go to the Local Group Policy Editor. To go to this section, it is necessary to disable the function of Tamper Protection within the same section where real-time protection is temporarily disabled.
To do this, we look for theLocal Group Policy Editor«, or gpedit.msc. In there, let’s Computer Configuration > Administrative Templates > Windows Components > Microsoft Defender Antivirus. Once we get there, we look for the option «Disable Microsoft Defender Antivirus«. We double click, and we give Enabled. Now we just have to restart, and we will have the Windows 10 antivirus permanently disabled.
These are the best options we have for disable Microsoft Defender in Windows 11. Another option is to use programs like Defender Control or Configure Defender. This type of program allows you to manage a multitude of settings directly from the program and with a couple of clicks without having to navigate through the system settings.
ALL LG Smart TVs can be hacked through the Internet and DTT
The SmartTV They have all kinds of protection mechanisms against vulnerabilities. Some even integrate antivirus to prevent malware from entering them, and all their apps are carefully analyzed. However, they always end up discovering vulnerabilities, so some people prefer not to connect tvs to the internet. The problem is that they got to hack some remotely without even having them connected to the Internet.
The vulnerability has been discovered by the hacker David Buchanan, also know as retr0id. This fault consists of remote code execution via DVB-T standard. In other words, the broadcast of the exploit is carried out through the signal that reaches DTT through the antenna socket. Needless nor that the TV is connected to the Internet in order to exploit the vulnerability.
It hacks through DVB-T and HbbTV
The error consists in executing scripts to generate a DVB-T transmission with metadata from HbbTV, the standard used LovesTV. With these scripts, a web page is loaded on top of the video feed, containing a V8 n-day exploit. Buchanan says that now all he needs to do is find another vulnerability that allows him to escalate privileges on the TV for even more absolute control.
The exploit works on a 2019 LG Smart TVs. Until now, this type of attack required the Smart TV to be connected to the Internet, but now all it takes is for it to be turned on. Buchanan says it may also be possible to hack a TV that’s turned off, but he needs to keep testing.
The bug is still unpatched on LG TVs, whose latest update was released last January 13th. The vulnerability has been published on January 14, so LG has not had time to fix it yet. Although the bug has been exploited on a 2019 TV, Buchanan says the bug can be exploited on 2020 and 2021 models. However, these models use newer versions of Chrome as their browser, so an n-day exploit will be needed. different.
In the video that Buchanan has uploaded to his Twitter account, you can see how you can get almost total control of the TV, showing notifications, messages, and even choosing the video you want to play on it.

The vulnerability demolishes all those comments that say that “if you are concerned about your privacy, do not connect the TV to the Internet”. Now, it is possible to hack LG TVs without them being connected to the Internet. However, the flaw can be mitigated by disabling HbbTV’s autostart feature, although Buchanan says that many other vulnerabilities remain in DVB.
I just got DSMCC Carousels working.
That means the exploit still fires even if the TV is not connected to the internet. The entire exploit is served over the airwaves.
Everyone who said “just don’t connect it to the internet” can shut up now 😛 https://t.co/KSYMsdVmqo

Any LG TV can now be rooted
With this exploit it is possible root lg tv. There is a tool called RootMyTV, which makes it easier to take advantage of the vulnerability to install the homebrew channel on a TV after rooting it. Thanks to this, it is possible to install unauthorized applications and created by the community, such as moonlit to remotely play your PC games (since webOS does not have the Steam Link app), YouTube with enhanced features, RetroArch to play emulators, and many more to come in the future.
After the vulnerability, they have updated RootMyTV to the version 2.0, where, just by entering the website of rootmy.tv from an LG television, it is already possible root it to install apps on it. All current LG models can be rooted with this method, including those updated to version 04.30.57 released this week. The automatic system updates are disabled after rooting in case there is any problem with the updates. In case you want unroot, you just have to do a factory-reset of the TV to return it to the factory settings, so the method is quite safe.

Security problems detected in the official app of the Olympic Games
On the eve of a new edition of the Winter Olympics that will take place in Beijing, China, during the next month, a series of security problems were detected in an official application of the sporting event, which is expected to be widely used by athletes and reporters who will attend the instance.
Citizen Lab, an Internet security firm, said in a report that the MY2022 application has serious deficiencies in its encryption, a condition that would make users’ confidential data, plus any other data communicated through said app, vulnerable to being pirated. Other important user data in the app was not encrypted at all, according to the report.
Olympic committee app has vulnerabilities
The above implies that the data transmitted through the application could be read by Chinese Internet service providers or telecommunications companies through Wi-Fi access points in hotels, airports and Olympic venues.
Specifically, according to citizen lab report, the MY2022 app shares information directly with some Chinese companies such as Huawei, Xiaomi, Oppo, Vivo, Meizu, Tencent, Weibo, AutoNavi and iFlytek, varying the type of data according to each case. Also, the presence of invalid SSL certificates was reported, a condition that hinders the encryption of sensitive information.
The report indicates that the application is mandatory for those attending the sporting event. Without going too far, the official guide of the International Olympic Committee instructs attendees to download the application before visiting China. However, the IOC issued a statement yesterday, noting that this smartphone app was not mandatory. The IOC also rejected the Citizen Lab report, saying that two independent cybersecurity testing organizations had found no critical vulnerabilities with the app.
China is requiring all international Olympics attendees, including coaches and journalists, to log into a health monitoring system at least 14 days before they leave. They can use the app to do this, or they can still log in through a web browser on a PC. The app allows its users to submit required health information on a daily basis and is part of China’s aggressive effort to manage the coronavirus pandemic as it hosts the games, which begin on February 4. The app also has chat features, file transfers, weather updates, tourist recommendations, and GPS navigation.
Given the environment with these technologies, many countries are advising their athletes not to bring their normal smartphones to China, but to bring temporary phones, or burners, that do not store any sensitive personal data, according to news reports.
