Android and Sideloading

It is well-known among hackers that they are constantly on the lookout for new methods to infect computers with harmful software and steal critical information. They have the option to sideload.

It’s possible that you’ve heard of the phrase “sideloading” if you have an Android device. With this capability, it is possible to download and install applications from a variety of different sources. Individuals seeking complete freedom may find this advantageous, while others may find it a nuisance.

You should only download information from reputable sources. Unless you take these steps, you will leave yourself open to data breaches and other security risks.

Safety When Using Public WIFI

How can we ensure the security of our data when using public WiFi?

Most people are unaware that free public Wi-Fi isn’t protected by encryption. Your online actions aren’t always safe, even if you have to provide a password to get in. Your online personal data is at danger if you connect to a public Wi-Fi network without using proper security measures.

Connect to websites using HTTPS, which encrypts all data sent to and received from the website throughout the connection process. The difference between HTTPS and VPN is that HTTPS encrypts all of your communication whereas VPN encrypts only the communication to and from a certain website.

Check the address bar of your browser window to see whether you’re connected using HTTPS; you should see the letters “HTTPS” at the beginning of the site URL if you’re connected using HTTPS. Additionally, in some web browsers, you may notice a lock icon.

On top of that, you can protect your data by using two-factor authentication wherever feasible. This kind of application (such as Authy) mandates the usage of a password as well as a secondary code that is updated on a regular basis for websites and apps. Attackers are constantly on the move, searching for loopholes to access personal information. Thankfully with two-factor authentication, there is no way hackers would get the secondary code even if your password is obtained.

How to Increase Download Speeds

If your computer speeds are lagging, here are a few ways you can try to increase productivity.

You may run a speed test online to find out how fast your download and upload speeds are in reality. If the test results appear to be positive, see that there isn’t anything downloading or uploading in the background that might be affecting the performance speed.

Checking to see whether the manufacturer of your network card has released a new driver and installing it may assist to accelerate downloads. If there is nothing downloading or uploading in the background and there is no network card update, resetting the router and modem may be necessary to resolve the issue. It may be beneficial to disconnect the power cord from the router or modem for 1-2 seconds.

Even if you are still experiencing connectivity issues, you should call your Internet service provider to see whether the problem is on their end or on yours. Your service provider will have the opportunity to re-establish the primary connection if the situation warrants it.

Outdated Apps Getting the Boot

Apple recently shared an update on their App Store Improvements project.

This one shouts out to developers, stating if their applications are out of date, it will be removed from the App Store. The policy says that if your app hasn’t been updated in the last three years and doesn’t have a certain amount of downloads, you’ll receive an email notifying you that your software has been reported for removal from the App Store altogether.

However, developers are speaking out against it. According to MacRumors, “Many of the affected developers objected to Apple’s policy, noting that their apps continued to function just fine despite a lack of updates, highlighting the amount of work that might be needed to submit even a minor update, and pointing out that many apps can exist as finished works without a need for continual updates.”

Thankfully, Apple announced the deadline for app updates has been extended from 30 days to 90 days.

Windows Update Ransomware Exploit

Magniber ransomware is spreading like wildfire thanks to a coordinated effort that began in early April and involves the exploitation of bogus Windows 10 patches.

What is ransomware?

In the simplest words, ransomware is a type of malware that affects your computer and demands a ransom in exchange for access to it. It encrypts all of your files and directs you to contact the hacker in order to negotiate a payment arrangement. As a result, we have RANSOMware!

According to BleepingComputer, “Based on the submissions to VirusTotal, this campaign appears to have started on April 8th, 2022 and has seen massive distribution worldwide since then. While it’s not 100% clear how the fake Windows 10 updates are being promoted, the downloads are distributed from fake warez and crack sites.”

This particular exploit targeted consumers instead of companies.

To avoid any and all unwanted cyber assaults, make sure that your antivirus software is current on your computer. Keep in mind that Windows 10 and 11 updates are sent through the operating system. Microsoft will never send updates through other channels such as e-mail or social media.

New Windows 11 Feature Available

A new dedicated feature coming to Windows 11 has tech blogs talking. Named “Voice Clarity”, this particular newcomer is being tested to some PC’s, but not all.

According to WindowsLatest, “Unlike Teams noise cancellation, which is baked into the Teams app, Microsoft’s new Voice Clarity feature works at the OS level and it aims to capture the entire audio spectrum of your audio at higher bandwidth.”

For now, it’s said Voice Clarity only works on Surface laptop Studio, but will hopefully start rolling out to other devices soon.

A Brief Insight of File Extensions

Following the last period in a file name, a series of characters known as the file extension, or file name extension, is used to identify the file and locate it in the file system.

For example, the file extension “.txt” is the same as the word “txt” in the dictionary. As soon as you double-click on a file, the extension informs the version of windows about the sort of file you are opening and the software you want to run.

Aside from the fact that it must begin with a period and have at least one letter, there are no additional formatting requirements for an extension. In most cases, file extensions are made up of three characters, which can be either letters or numbers, and which textually describe the type of file being referred in the text. Text files, mp3 files, jpeg picture files, and files compressed using the gzip application are all signified by the file extensions.txt,.mp3,.jpg, and.gz. Text files, mp3 files, jpeg picture files, and files compressed using the gzip application are all denoted by the file extension.txt.

Text files, mp3 files, jpeg picture files, and files compressed using the gzip application are all denoted by the file extensions.txt,.mp3,.jpg, and.gz. The file extensions.txt,.mp3,.jpg, and.gz denote text files, mp3 files, jpeg picture files, and files compressed using the gzip application, respectively.

This information is contained inside the extension’s real name. It shows you what sort of file is being referenced to and where it is located.
