Malware on Android

Over 1.5 million Android users are at risk of two file management apps secretly sending user data to servers based in China using spyware. What’s worse, both apps hide from the home screen, making deleting them harder.

Spotted by mobile security company Pradeo, the malicious apps caught on the Google Play Store are named File Recovery & Data Recovery and File Manager. Posing as legitimate-looking file management applications, both claim not to collect sensitive data from the user’s Android device. However, they reportedly steal contact lists from emails and social media accounts, user location, device information, network provider name and media such as photos, video and audio.

Threat analysts state that the two apps send a large number of transmissions of stolen data to malicious servers based in China, which is “an amount that is so large it is rarely observed,” the report says. While the apps claim that no data is collected, it also states that if any information is gathered, users can’t request it be deleted. Understandably, this is shady, as the report points out that this goes against data protection laws.

File Recovery & Data Recovery and File Manager have over 1.5 million installs, with the former having 1 million and the latter gaining 500,000 users. They come from the same developer, listed as Wang Tom. To make it harder for users to delete these apps, the developer uses known malware tactics, such as forcing a restart to allow the apps to launch and execute.

The spyware-infected apps also hide themselves from the home screen, tricking users into thinking they no longer have the apps and making it difficult to delete them. Instead, users must head into app settings on their Android device to uninstall these malicious apps.

As per BleepingComputer, Google has removed both apps from the Play Store. Still, users should be cautious of any recent file management apps they have downloaded and ensure they aren’t lurking around on their devices.

What is spyware?

Spyware is a type of malicious software (malware) that sneakily obtains information on a device without the user’s knowledge and sends it to a threat actor. The stolen data can be anything from device information to personal files, photos, videos and more, which can be used to violate the user’s privacy or harm their device. This can lead to stolen passwords, banking accounts or sensitive information.

Spyware can infect devices by disguising themselves as legitimate software, such as an app or email attachment, to trick users into believing what they’ve installed is harmless. Spyware can put a user’s personal safety in danger without any awareness of the device being infected.

Since spyware can be used to track everything a user does, including the websites visited, communications between contacts and apps used daily, it can be easy for an attacker to obtain an assortment of information about a user. This can be used to harm the user directly or can be sold on dark web markets to malicious actors looking to exploit this information.

This nasty type of malware can easily slip past the defences of a device, which is why it’s a good idea to keep an antivirus on at all times to fortify your device.
