Ginp malware removal guide

What is Ginp?

Cyber criminals abuse the current situation (spread of COVID-19) in various ways. In this particular case, they attempt to extort banking information from unsuspecting people through a website called Coronavirus Finder. This web page is opened via a banking Trojan called Ginp. Currently, cyber criminals responsible target mainly Android users in Spain, however, they could also be targeting people in other countries.

Coronavirus Finder is a deceptive web page suggesting that visitors can find out the location of people who are infected with the coronavirus (COVID-19). At the time of research, this page claimed that there were twelve infected people nearby and offered to display their location for 0.75 EUR. To pay for this service, visitors must supposedly provide credit card information such as card holder name, credit card number, expiry date and CVV. By providing these details, visitors would simply present cyber criminals with their credit card details, which could then be misused to make fraudulent purchases and transactions, or simply sold to third parties. Therefore, Coronavirus Finder and other similar sites can never be trusted. Note that a previous Ginp version was designed to trick users into providing various privileges through Accessibility Service. I.e., it asked permission to display push notifications that would open fake web pages or software designed to appear as legitimate apps asking to enter login credentials, credit card details or other personal information. In this way, cyber criminals used Ginp to perform 'overlay attacks'. These cyber criminals send a special command to Ginp, which opens Coronavirus Finder.

Malware Removal (Windows) To eliminate malware infections our security researchers recommend scanning your Android device with legitimate anti-malware software. We recommend Avast, Bitdefender, ESET or Malwarebytes.

Ginp is similar to another banking Trojan called Cerberus, which is employed for the same purpose: to steal confidential information, which could be misused to generate revenue in various ways. Users with devices infected with this malware are exposed to risk of monetary loss, online privacy issues and other problems. Therefore, take precautions when using mobile or desktop devices.

How did Ginp infiltrate my device?

Commonly, Trojans targeting Android devices exploit Accessibility Service features - this allows cyber criminals to control mobile telephones remotely and perform certain actions. For example, display push notifications that, if clicked, launch certain apps, delete applications, access contact lists, list installed apps, trigger overlay attacks, open various dubious websites, etc. Accessibility Service is often exploited through fake Flash Player installers and untrusted websites that are usually disguised as official web pages of various apps/companies.

How to avoid installation of malware

Do not download files or programs from untrusted channels such as Peer-to-Peer networks (torrent clients, eMule, and so on), unofficial websites, third party downloaders, etc. Use only official web pages and via direct links. Also avoid third party installers. Do not open attachments or website links within irrelevant emails that are sent from suspicious, unknown addresses. Installed software must be updated and activated (if necessary) with tools and functions that are provided by official developers. Third party tools are often used to spread malware. Furthermore, it is illegal to activate licensed programs with unofficial ('cracking') tools. Keep devices safe by regularly scanning them for threats with reputable antivirus or anti-spyware programs.

Note that some malicious applications might be designed to operate when the device is connected to a wireless network only. For this reason, you should check both Mobile and Wi-Fi data usage.

Checking data usage of various applications in the Android operating system (step 3)

If you find an application that uses a lot of data even though you never use it, we strongly advise you to uninstall it as soon as possible.

Install the latest software updates:

Keeping the software up to date is a good practice when it comes to device safety. The device manufacturers are continually releasing various security patches and Android updates in order to fix errors and bugs that can be abused by cyber criminals. An outdated system is much more vulnerable, which is why you should always be sure that your device software is up to date.

Go to "Settings", scroll down until you see "Software update" and tap it.

Installing software updates in the Android operating system (step 2)

Performing a "Factory Reset" is a good way to remove all unwanted applications, restore system settings to default and clean the device in general. Bear in mind, however, that all data within the device will be deleted, including photos, video/audio files, phone numbers (stored within the device, not the SIM card), SMS messages, and so on. I.e., the device will be restored to its initial/factory state.

You can also restore the basic system settings and/or simply network settings.
