Elon Musk is continuously working on satellite networks. Apart from this, there are many other companies which are working on satellite network. Today we will tell you how this network works. Also how can you make calls without a SIM card. So let us give you this information also-
Satellite Network-
Talking about satellite phone, satellite is completely used for communication with it. It does not require any telecom network to make calls to any corner of the world. It is still used in emergency situations. When a disaster occurs in a country and the mobile network is completely shut down. There are many areas where remote networks work. The special thing is that satellite phones are handy and it becomes easy to carry them from one place to another.
How does a satellite phone work?
This phone directly means that it will work on satellite network. You will have to depend on the satellite network even if you contact landline, cellular or any other phone. Information signals come only with the help of satellite. You use satellite phones to communicate both by voice and text.
Satellite phones have omnidirectional or directional antennas that use the same antenna for transmitting and receiving signals. The phone must have line-of-sight to receive a service signal. Whereas, using the network becomes much easier in satellite phones. It is currently used on ships, planes, vehicles, ground based phones and command centers. This network proves to be very good. However, there are many different types of networks in this too.

Microsoft Discovers Critical Android Malware ‘Dirty Stream’ That Hijacks Legitimate Apps
Warning: Android Users at Risk from Critical Security Vulnerability
Android users are once again under threat from a new strain of Android malware named “Dirty Stream.” Microsoft has flagged this critical security vulnerability that enables malicious apps to hijack legitimate apps, impacting numerous Android devices with hundreds of millions of installs, spanning even the best Android phones on the market.
Understanding the Vulnerability
The vulnerability lies within the ContentProvider system, a core element of many popular Android apps that facilitates communication and data sharing between different applications. Necessary security measures like strict data isolation, specific URI permissions, and path validation are in place, but hackers have discovered a way to exploit the system using “custom intents.”
By utilizing custom intents, hackers can send manipulated files with seemingly legitimate names or paths to vulnerable apps, thereby executing unauthorized and malicious code, compromising critical files, and stealing sensitive data right under users’ noses.
Scope of the Threat
Microsoft’s investigation shows that this security vulnerability is widespread. They have identified a significant number of vulnerable applications, exceeding four billion installations collectively, with two popular examples being Xiaomi Inc.’s File Manager (1B+ installs) and WPS Office (500M+ installs).
Given the nature of the vulnerability, it is difficult to determine how many other legitimate apps have also been affected. However, it is advisable to exercise caution and assume that the scale of the threat remains large until all apps have been patched.
Protecting Against Android Malware
To safeguard your Android device from potentially harmful malware, it is imperative to avoid sideloading apps and rely on official app stores such as Google Play Store, Samsung Galaxy Store, or Amazon Appstore, as apps hosted on these platforms undergo stringent security checks.
Ensure that Google Play Protect is enabled on your Android smartphone, as it actively scans existing and newly downloaded apps for viruses. Additionally, consider installing one of the best Android antivirus apps for an added layer of protection.
Stay Updated
Stay informed about the latest developments and updates on this security vulnerability. Regularly check for software patches and security updates for your Android apps to mitigate potential risks.
