Android users have been warned about a malicious bug that has affected millions of devices.
The bug, called Necro, has infiltrated androids via certain apps and is capable of stealing personal data and signing people up for costly subscriptions without their consent.
According to cyber security firm, Kapersky, who first identified Necro in 2019, the malware tends to be installed on apps known as mods.
Mods are modified versions of official apps such as WhatsApp and Spotify that claim to offer additional features.
Most are unofficial, not on Google Play and tend to be offered at a cheaper price than their counterparts or for free, reports The Mirror.
However, a few apps on Google Play have also been infiltrated.
According to Kapersky, among them is a photo editing app called Wuta Camera, which was downloaded 10 million times before Necro was discovered and removed.
Kaspersky offers a few tips on how you can stay safe from Necro.
Firstly the company strongly advises against downloading apps from unofficial sources, as these apps are often much easier to infiltrate with bugs.
Although you can download apps from official platforms such as Google Play, it’s best to approach each app with caution.
Check the app’s page in the store first and look to see it has reviews with low rating, as these can offer warnings about possible issues.
Also when an app has lots of rave reviews and an overall high score be wary as it could be fake.
Finally, avoid using modified apps or hacked versions as they could have been infiltrated.
