While doing some development work I realized everytime I would install a test build of my app on my phone Android Monitor (AndroidStudio) will show me a log basically posting that install to a chinese server. I couldn't figure out which app was doing it. So I intstalled a firewall and blocked all app's and then one by one started checking which is reporting.

To my surprise it was ShareIt, the app has over a 100 million installs and it is reporting every install and uninstall you do on your device to a chinese server along with device information, country, time, language settings and more. (Screenshot below)

Upon looking into it more it turns out an app doesn't need any permission to get install and uninstall event on a device. I am just amazed that an app this big can get away with something like this. Thought will drop a note on this thread and make everyone aware.

Today I installed ShareIt Windows software from ShareIt official site. Software installed correctly without any issue, but when I opened it, I am getting prompt "The port 55283 was occupied". I want to know What is port 55283?. Who is occupied that port & Why I am getting this error. I am using Windows 10 OS. I had attached the screenshot of error that I am getting.

that is because you have two versions of shareit installed. First, uninstall the pc application. Second, there might be an application installed using the Microsoft store. Make your pc free of all the instances of the application. Again install, and make sure you open it with the same shortcut that got created.

It also provides a feature that can install an APK with the file name suffix sapk. This feature can be used to install a malicious app; if such is the case, it will enable a limited RCE when the user clicks on a URL.

Even if the download and installation of APK by Chrome deep link were not successful, the same attack can still be performed by downloading the APK from an arbitrary URL and Install APK under an arbitrary path by using this code via a malicious app locally:

Lastly, the app is also susceptible to what's called a man-in-the-disk (MitD) attack, which arises when careless use of "external storage" permissions opens the door to the installation of fraudulent apps and even causes a denial of service condition.

SHAREit - Connect & Transfer is an app for speedy transfers between all kinds of devices. The only thing is that you have to install this app on both ends. Meaning, that both the receiving and sending smartphone or tablet must have SHAREit - Connect & Transfer running for transfers to complete.

Downloading SHAREit for Windows allows you to pair your PC with a smartphone with the Android app installed. This way, you can share a lot of data securely and reliably without connecting your devices to the Internet.

Trend Micro says it has found "several" security flaws in the popular Android app ShareIt. ShareIt has been downloaded over a billion times from the Play Store, and, according to App Annie, was one of the 10 most globally downloaded apps in 2019. The app was originally developed by Lenovo (it has since spun off into its own company) and for a time was pre-installed on Lenovo phones.

Trend Micro's report details a laundry list of bad decisions made while designing ShareIt that could make it more susceptible to malicious code. One problem is a common Android app vulnerability that arises when developers set up a content provider incorrectly. Android prides itself on intra-app communication, partly because any app can create a content provider and provide its content and services to other apps. If Gmail wants to attach a file to an email, it can do that by showing a list of available file-content providers installed on your phone (it's basically an "open with" dialog box), and the user can pick their favorite file manager, navigate through their storage, and pass the file they want to Gmail. It's up to developers to sanitize these cross-app capabilities and only expose the necessary file manager capabilities to Gmail and other apps.

The file paths ShareIt will offer up are limited to its own data files, but that means apps can edit the data ShareIt uses to run, including the app cache that gets generated during install and runtime. The report says that "an attacker may craft a fake [app cache] file, then replace those files via the aforementioned vulnerability to perform code execution." Normally these files live in private storage, but ShareIt's private storage is open to the world.

ShareIt also comes with its own Android app installer. With its private storage no longer being "private," it repeats the same mistakes we saw in Epic's Fornite installer. It downloads app install files to world-readable storage, where they are vulnerable to a "Man-in-the-disk" attack. App install files need to be protected in private storage before they are installed, but in public storage, the install package could be swapped out as soon as it is downloaded but before install time. Then the user thinks they're installing the good app they just downloaded, but it's actually an imposter malicious app.

A whole extra problem is that ShareIt's game store can apparently download app data over unsecured HTTP, where it can be subject to a man-in-the-middle attack. ShareIt registers itself as the handler for any link that ends its domains, like "wshareit.com" or "gshare.cdn.shareitgames.com," and it will automatically pop up when users click on a download link. Most apps force all traffic to HTTPS, but ShareIt does not. Chrome will shut down HTTP download traffic, so this would have to be done through a Web interface other than the main browser.

Trend Micro ends by saying, "We reported these vulnerabilities to the vendor, who has not responded yet. We decided to disclose our research three months after reporting this since many users might be affected by this attack, because the attacker can steal sensitive data and do anything with the apps' permission." Users should probably uninstall the app ASAP. If you're looking for a more secure file-sharing alternative, Google's file manager can do local sharing over Wi-Fi now and should be written with better security practices.

With the rise in popularity of file sharing applications, Shareit has become one of the most widely used apps for transferring files between devices. However, like any other app, users may encounter certain issues during the download and installation process. In this article, we will discuss some common problems that users face when trying to install Shareit and provide troubleshooting tips to overcome them.

One of the most common issues faced by users during the Shareit app installation is compatibility problems. Shareit is available for various platforms such as Android, iOS, Windows, and Mac. However, it is important to ensure that your device meets the minimum system requirements for running the app.

If you are using an Android device, make sure that your operating system version is compatible with the version of Shareit you are trying to install. Similarly, for iOS devices, check if your device supports the required iOS version. Incompatible operating systems can cause installation errors or prevent the app from functioning properly.

Another frequent issue encountered during Shareit app installation is insufficient storage space. Shareit requires a certain amount of free space on your device to be able to download and install it successfully. If you do not have enough storage space available on your device, you may encounter errors or experience slow download speeds.

To troubleshoot this problem, try freeing up some space on your device by deleting unnecessary files or apps. You can also move some files to an external storage device if available. Once you have created enough free space on your device, attempt reinstalling Shareit and see if it resolves the issue.

A stable internet connection is crucial for downloading any application from app stores or official websites. Slow internet speeds can lead to incomplete downloads or interrupted installations of Shareit.

Antivirus software and firewalls are essential for protecting your device from potential threats. However, sometimes they can interfere with the installation process of certain applications, including Shareit.

To troubleshoot this issue, temporarily disable your antivirus software and firewall settings before installing Shareit. Once the installation is complete, remember to re-enable them to ensure the security of your device.

Installing Shareit should be a straightforward process, but occasionally users may encounter issues that hinder successful installation. By understanding and troubleshooting common problems such as compatibility issues, insufficient storage space, slow internet connection, and antivirus/firewall restrictions, you can overcome these obstacles and enjoy seamless file sharing using Shareit. Remember to always keep your app updated to benefit from bug fixes and improvements provided by the developers. 006ab0faaa
