According to Apple’s release notes, the update provides an important security patch, which fixes two major vulnerabilities in the WebKit suite of apps that could allow hackers to break into a user’s iPhone. Apple recommends that users update immediately to iOS 14.5.1 as soon as possible. (Photo: iOS News And More) However, the recent version of iOS 14.5.1 that Apple released recently seems to continue to bring other troubles for iPhone users. Specifically, in a thread created by Reddit user LHG_93, this person complained about the battery life on his iPhone getting worse after updating iOS 14.5.1, even installing Resetting the device also couldn’t help. “Has anyone noticed that the battery life of the device is very poor after the iOS 14.5.1 update. Even reinstalling is not helping,” said LHG_93. (Screenshots) Below the thread created by LHG_93, many members on Reddit also said they are experiencing the same situation after updating to iOS 14.5.1. “I have, too, the iOS 14.5 update is better than iOS 14.5.1”, said member DRS-MICKY. “I also noticed the same thing. I’m using an iPhone 12 Pro”, according to member zangielv. “Using an iPhone 7 and also the same as the OP,” shared member PaulF1959. (Photo: iPadizate) “It’s hard to understand how, after 8 beta versions of 14.5 and then 14.5.1, battery drain continues to be an issue on iOS 14 … I also saw a lot of battery drain on iOS 14.5. first. I don’t understand why Apple didn’t fix this. My device isn’t even that old, it’s the iPhone XR. IOS versions 13.5-13.7 are better in terms of battery retention on the iPhone XR. After 8 beta versions, iOS 14.5 should have been much better, “said member xxGon. (Photo: ThinkApple) Not only was it complaining about battery drain, iOS 14.5.1 is also said to cause some iPhone models to have performance issues. Notably, this error seems to occur not only with older iPhone models such as iPhone 7, iPhone 11, … but also iPhone 12 Pro, iPhone 12 are also believed to have a similar situation.

Hackers can obtain sensitive user’s information through the vulnerability in AirDrop.

First, in order to provide users with the option “Contacts Only” in the AirDrop sharing feature, Apple devices silently collect information on devices within the connection range. To see if the “other party” is in the contacts list, AirDrop uses a mutual authentication mechanism, comparing the user’s phone number and email address with the entries in the address book. The device authentication step in the directory can be exploited to get information. Photo: Monica Chin. In the next step, data is exchanged for both parties. Despite encryption, Apple uses a relatively weak hashing mechanism. Security experts can decompile the hash using a simple technique like a brute-force attack. The team addressed the AirDrop vulnerability with a more secure approach, they named PrivateDrop. However, Apple did not move after being warned of the risk of personal information leaks and privacy breaches. In the immediate future, experts from the Technical University of Darmstadt advise users to protect themselves by disabling AirDrop discovery in the system settings and not opening the share menu. The detailed results of the study will be presented at the USENIX security Symposium taking place in August. Why does iPhone not have USB-C port? In the past 5 years, USB-C has become the suitable connector for a wide variety of devices such as Android phones, laptops and tablets. However, Apple still doesn’t make iPhones with USB-C ports.

AirDrop is very useful for Apple ecosystem users but is being warned of being insecure. Experts said, AirDrop allows users to share files with Apple devices in contacts. During the process of verifying the connection between devices, AirDrop uses a “mutual authentication mechanism” to compare the user’s phone number and email with the entries in the other device’s phonebook. Basically, data exchanged via AirDrop is encrypted by Apple, but this security mechanism is assessed by experts as relatively weak. In fact, Apple just scrambles the phone numbers and email addresses exchanged in the process of transmitting through AirDrop. This security mechanism can be easily circumvented using simple techniques like brute-force attacks. Also according to security experts at Technical University of Darmstadt (Germany), the above vulnerability was discovered in May 2019 and has been notified to Apple, but Apple still has no specific patch. to fix the problem. Airdrop is a feature that comes pre-installed on iPhone, iPad or Mac (depending on the version of the operating system). Helps iOS, Mac devices connect together and can easily share files wirelessly with each other very quickly without affecting the quality of the file. Airdrop has been integrated on iPhone, iPod, iPad devices using iOS 7 or higher. Macbook from 2012 with OS X Yosemite (10.0) higher (except Mac Pro mid-2012). In addition, AirDrop cannot be used with other operating systems (Android phones, Windows Phone phones …).

Through the Win32k vulnerability, hackers can gain access to your computer and have full control over the device, however, this requires user interaction. Security researcher Boris Larin at Kaspersky Labs said the vulnerability was exploited by a group of hackers called BITTER APT. Other vulnerabilities such as the Windows NTFS denial of service vulnerability have not been actively exploited. But Microsoft notes that they have been publicly disclosed, meaning everyone knows about them. To limit attack, users should update the operating system as soon as possible by clicking on the Start menu and selecting Settings – Security & Update – Windows Update – Check for Updates. Recently, Google has just released two patches for Chrome browser on the computer, although they do not provide detailed information, both vulnerabilities are labeled “high” and have been exploited by hackers. To update Google Chrome browser, click the three-dot icon in the upper right corner, then select Help – About Google Chrome (about Google Chrome), finally click Relaunch to restart. Browser.
