Not stopping there, things are even more dangerous when two other vulnerabilities can be exploited by hackers to manipulate arbitrary files with higher permissions. What makes these even scarier is that they can be exploited without any user interaction. Samsung is aware of these security flaws and it may take the company about 2 months to fix. For now, the best defense is to make sure your Samsung phone is up to date with the latest firmware. Toshin said he has found more than a dozen vulnerabilities in Samsung devices since the start of the year, with many of these vulnerabilities already fixed. One of the bugs lies in apps and components like the Secure Folder app and the Knox security software that come pre-installed on Samsung devices. Tohsin told TechCrunch that these may have given attackers access to sensitive user data. Among +Samsung devices, the Galaxy S10+ is verified as affected. Another vulnerability resulted in the deletion of all previously downloaded apps once device admin rights were granted to a newly installed app. Additionally, a vulnerability in the Settings app could grant read/write access to files with system user-level privileges. A security flaw that was resolved in February could have given hackers access to users’ SMS/MMS messages and call details. Toshin also warned Samsung about issues that may have helped bad guys get the SD card content. While Samsung says the vulnerability affects “certain” Galaxy devices, the company appears to be downplaying the scope of the incident. “No issues have been reported globally and users should rest assured that their sensitive information is not at risk. We have addressed the potential vulnerability by developing and releasing security patches through a software update in April and May 2021 as soon as we identify the issue.” Korean company stated.

Securing the wifi router is the first step homeowners need to take to protect their smart home. During use, it is recommended to update the router’s firmware and always use a complex password for the wifi router. If the router manufacturer does not provide new firmware, users should consider replacing it. Just like not checking your bank account from public wifi, homeowners should avoid accessing smarthome from an open wifi network, but if you need to remotely access your home, use a private network. Using a separate wifi for smart home systems is necessary because sharing a wifi system has many potential safety risks. Smarthome prioritizes the system to be able to self-alert to abnormal intrusion to ensure safety, so users should use devices with automatic alarm setting feature. When there is an unusual intrusion, a notification will be sent to the homeowner’s phone immediately. In smarthome, not only home lock, smart home control applications need abnormal login warning feature, this helps homeowners recognize the risk of network attack to implement instant protection options. then. In a smart home, if there is a smart speaker with a screen or camera, users should consider turning off or covering the camera when there is no need to use it. This is similar to the fact that many people have a habit of covering the webcam on their laptop to avoid unfortunate images being recorded. Smart devices of unknown origin are at risk of being installed with spyware, which is easy to lose control and have data stolen. To be safe, it is recommended to use equipment from reputable companies, need to check the company history, product support period. From this information, a decision can be made whether to buy the product or not. And more specifically, it is very important to check the owner of the servers that will contain his home’s information because most smarthome devices used in the home communicate with servers in the cloud. In the process of studying the operation of the smart home control system, security experts have discovered serious security holes. Security flaws in the cloud infrastructure and remote code execution, causing a third party to acquire the “super user” right to access and control the smart home system. Immediately, the above findings were shared with smart home providers to immediately address these dangerous security holes. With a smart home, each device inserted into the smarthome can also be a point for network attackers to take advantage of, intrude on the home system …, so smart home security is very necessary for those who want Design your own smart home.

Photo: TomsGuide Nintendo Switch is one of the great inventions of the 21st century when it redefined a handheld gaming device. Although this device has not been appreciated for hardware and display quality compared to competitors like PS5 or Xbox, many sources have pointed out that the Nintendo Switch Pro version with a powerful configuration will be released this year. Up until now, Nintendo has yet to confirm the existence of this upgraded model, but that has not stopped the rumors that continue to be revealed about the Nintendo Switch Pro. Interestingly, when asked about the viability of a Nintendo Switch Pro model, Bowser told Polygon “we believe we are in the middle of the life cycle”. Is that a hidden answer to the right time for a new upgraded version? Pro version price So far, there has been no official announcement about the price of the Nintendo Switch Pro. However, due to the improved hardware and performance, we can be sure that this new version of the Switch will be more expensive than its predecessor. According to Bloomberg Intelligence analyst Matthew Kanterman, he believes the Switch Pro will be at least $ 100 more expensive than the base model of just $ 299. “$ 349.99 increases the value of the device, but I think Nintendo still has a large number of customers at $ 399.99.” Not just Kanterman but in an interview with Gamesindustry.biz, games analyst-Dr. Serkan Toto suggested the Switch Pro will cost around $ 399. Specifications of the Nintendo Switch Pro Most sources have made different predictions about the specifications on the Switch Pro version. However, the majority of them claim that the Nintendo Switch Pro supports 4K resolution in docking mode, as well as better battery life. Recent rumors include that a data miner has found signs in the Switch’s firmware code, suggesting that there will be a new Switch model in terms of display. SciresM data miner said the new system is codenamed Aula: “I don’t know if it is 4K or not. But Aula’s firmware does support a few Realtek chips that have been introduced as a “4K UHD multimedia chip”. This helps us know the chipset will deliver more performance by being pushed to higher clock speeds supported by an improved cooling system. While Economic Daily News in Taiwan claims that instead of an OLED display, the Nintendo Switch Pro will feature Mini-LED technology as a more economical alternative. However, other sources disagree with Economic Daily News. Currently, almost all information is directed towards Samsung supplying new OLED panels for Nintendo. In an exclusive interview with Ross Young, co-founder and CEO of Display Supply Chain Consultants, discussed the potential of Switch Pro with an OLED display and the pros and cons that this technology can bring. . “LCD screens use maximum brightness, whether it’s a white or black image, but OLED doesn’t,” Young said. “Their power consumption varies with content. So it will depend on the type of content you are displaying. OLED screens have a big advantage if they show video, but if it’s a video game with lots of bright colors, the OLED can consume more power. According to updated information from Bloomberg, Nintendo is also teaming up with NVIDIA Corp to produce a new graphics chipset that powers the Nintendo Switch Pro. Features of Nintendo Switch Pro The success that Nintendo Switch and Lite series bring to the manufacturer is undeniable. So the hero will not be too surprised when the Nintendo Switch Pro is still the handheld game combined with the desktop like its predecessors. According to a patent recently filed by Nintendo, the company appears to be working on a fitness tracking device potentially included in the Switch Pro. The translation of the 61-page document shows that this patented device contains a fitness tracker similar to what you find on a smartphone, capable of tracking your sleep. , track your mental health indicators and assessments. For now, indications suggest that the Nintendo Switch Pro may feature fitness tracking, presumably designed to work with health-related games like Ring Fit Adventure. Expectations in Nintendo Switch Pro – Improved screen quality to 1080p: Currently users are using the models with 6.2 inch 720p screen. This is a pretty poor experience compared to the competition. – Improved durability: One of the biggest minus points of previous Switch models is poor durability. The camera body will be scratched and peel off the paint quickly after a short time of use. In addition, the durability of the Joycon is not too high when they often have the phenomenon of the switch after about 1 year. 4K support in docking mode: The 4K console gaming community is growing day by day, and you can thank in part PlayStation 5 and Xbox Series for that. Unfortunately, the comparison with new generation consoles like the Switch is not appreciated because the image output to the TV is not as optimized as the competition. – Bluetooth support for third-party accessories: While the Switch currently has Bluetooth 4.1, this feature is only for wirelessly connecting Joy-Cons and Pro controllers. This means that to connect accessories like headphones, you need an adapter, which is very redundant and annoying on a machine that costs nearly 9 million dong. The reason why users want Nintendo to release the Switch Pro version Right now, the main reason to buy the Switch is to play Nintendo exclusive games. According to reports by many Reddit users, some third-party games such as Pillars of Eternity, Wasteland 2 and WWE 2K18 have experienced lag lag when playing games on Switch. The Switch’s hardware is simply not built to provide a good experience for third-party franchises. The Nintendo Switch is not meant to compete with the PS5 and Xbox Series X in terms of power. However, with a collection of new graphically heavy games coming this year that require a higher configuration to experience, so users are looking forward to a new version with superior configuration. Help users experience a series of games in the smoothest way.

Recently, on social networks, there has been a situation of buying and selling clips from camera accounts stolen by bad objects. Depending on the quality of the content, the associations that sell the 18+ clip will collect a fee from 100,000 to 250,000 VND per joining. Not only providing depraved content, some groups also share hacked camera access accounts for a package fee of about 3-4 million VND. The fact that cameras are installed everywhere, the number of cameras is constantly increasing, making data from the camera a source of information targeted by many objects. (Artwork: Internet) According to experts of the National Cyber ​​Security Monitoring Center (NCSC), the Information Security Department, the Ministry of Information and Communications, the sale of account information on social networks is not a new behavior, but it has exported. appeared long ago. However, in the past, normally subjects only sold bank accounts, social networks or accounts containing information such as email, phone number, identity card number … Nowadays, when cameras are installed everywhere, the number is constantly increasing, being a source of information targeted by many audiences, the camera account also becomes “hot goods” on the account trading pages. “This form of purchase is becoming more popular because the number of cameras is increasing. Victims who lost their camera account can be monitored by others through their own camera, ”said the NCSC representative. Many users accidentally revealed the camera system login information According to experts, there are many reasons for the widespread purchase and sale of clips and camera accounts on the network, in part due to regulations and sanctions against acts of buying, selling and distributing personal data. not enough deterrent. Commenting on the reason that the personal camera system is vulnerable to hacker attacks, both subjectively and objectively, NCSC’s representative said: “Subjective is because users accidentally reveal account login information. camera. And objectively, because users use poor quality camera equipment, do not ensure enough information security, leading to the device can be hacked by hackers, thereby getting the login account “. Having the same opinion with the representative of NCSC, a security expert for IoT devices at Viettel Cyber ​​Security, Ha Toan, emphasized: A fundamental reason that makes personal and household cameras easy. Hacker attacks are due to the user’s limited knowledge of using IoT devices or cameras. For example, do not change the default password of the device when it is put into use. According to Toan, another reason is that the camera device of the manufacturer does not have a protection mechanism such as verifying the integrity of the firmware running on the camera device, allowing hackers to buy camera equipment and insert backdoors. (back door – PV) and then sold to the market. “During the work, we also discovered many backdoors allowing remote access in cameras originating in China”, Viettel Cyber ​​Security expert added. Along with that, there are cameras that have vulnerabilities in firmware due to programming errors such as buffer overflow, hardcode login information, logic errors … allowing hackers to exploit to take control of the device. Camera account information can also be revealed because the installation staff deliberately fails to notify the password change during installation or notice the change but does not notice the change of the entire service as mentioned above also includes services RTSP, onVIF. Raise awareness of personal information protection, choose a reputable camera To overcome the widespread situation of buying and selling clips, camera accounts in particular as well as personal information and data, experts say that the Decree on personal data protection should be issued soon and come to life. This draft Decree has regulated heavy fines for violations of personal data protection regulations. “The more penalties for handling violations related to the purchase and sale of personal data will help increase deterrence and reduce the rate of violation”, expert of Vietnam Cyber ​​Security Joint Stock Company (VSEC) Vuong Trong Nhan stated his point of view. But experts also emphasized the limitation in the sense of protecting personal data of users as well as the organization providing services related to user data. Making recommendations to users, VSEC experts advise them to first increase their sense of self-protection by not using the camera manufacturer’s default password, setting a strong password and setting a Private network system is only for indoor security equipment, instead of sharing the same Wi-Fi network. According to representatives of NCSC, individuals and businesses when using cameras need to have strict regulations and decentralization when allowing users to access their camera systems, need to change passwords regularly to avoid in case the login information is known by many people, the risk of leaking is also higher. Emphasizing on the safety factor of the device, experts say that choosing to buy cameras manufactured from major brands, products that have been assessed for information security as well as choose a reputable installation unit. is an effective solution to help users avoid the risk of information insecurity. On the other hand, is it time for camera manufacturers to pay more attention to whether their equipment meets information security requirements?
