If you've suddenly noticed duplicate copies of apps such as Instagram, Snapchat, WhatsApp, X (formerly Twitter ) and Google appearing on your phone or you've downloaded these services from unofficial stores you need to consider deleting them without delay.
Security experts at Sonic Wall have discovered a new threat and not something you want to ignore. It appears hackers are using these hugely popular platforms and trusted brands to infect devices with vicious malware and it could leave your personal data exposed.
Once installed, the fake applications look just like the real deal with the icons on the screen looking no different from the actual software.
However, despite appearing innocent enough, they hide a nasty surprise with Sonic Wall saying "the malicious app aims to carry out harmful actions or steal sensitive information without the user’s awareness or consent."
One of the telltale signs that something isn't right is the permissions these apps will want you to agree to. Once installed, you'll be asked to grant the app access to things such as Accessibility Service and Device Admin Permission.
"By requesting these permissions, the malicious app aims to gain control over the victim’s device," Sonic Wall added.
Being able to sideload apps away from Google's official store is what makes Android so popular but this is a good example of when things can go seriously wrong.
Before installing anything onto your device always check that the developer is real and has a good reputation.
If possible read the reviews and always be careful what permissions you grant anything installed away from the Play Store.
If you think you've downloaded anything dangerous, it's a good idea to delete it without delay.
