Google has eliminated a pretend Netflix app from the Play Retailer that aimed to unfold malware by robotically responding to your WhatsApp messages.
Earlier this 12 months, the safety agency Test Level Analysis, discovered that an app named FlixOnline was assuming the look of Netflix, and promising two months of free subscription by way of WhatsApp messages.
Nevertheless, a hyperlink connected to those messages would redirect you to a web site to simply seize your particulars, together with your bank card.
Right here’s how the malware labored. When you put in the FlixOnline app from the Play Retailer, it requested for primarily three kinds of permissions: display overlay, battery optimization ignore, and notification. Researchers from Test Level famous that overlay is utilized by malware to create pretend logins and steal person credentials by creating pretend home windows on prime of present apps.
The app “listened” for notifications, and robotically replied to your WhatsApp chats with a message that seemed like this:
“2 Months of Netflix Premium Free for free of charge For REASON OF QUARANTINE (CORONA VIRUS)* Get 2 Months of Netflix Premium Free wherever on the earth for 60 days. Get it now HERE https://bit[.]ly/3bDmzUw”.
The hyperlink, in fact, was a phishing web page to gather your info.
Aviran Hazum, Supervisor of Cellular Intelligence at Test Level Software program, stated that this can be a novel methodology of spreading malware, and whereas this app is faraway from the Play Retailer, it might return in one other type:
The malware’s method is new and modern, aiming to hijack customers’ WhatsApp account by capturing notifications, together with the flexibility to take predefined actions, like ‘dismiss’ or ‘reply’ by way of the Notification Supervisor. The truth that the malware was capable of be disguised so simply and finally bypass Play Retailer’s protections raises some critical pink flags. Though we stopped one marketing campaign utilizing this malware, the malware could return hidden in a distinct app.

Attackers making functions and web sites that masquerade Netflix will not be a brand new development. It was one of the vital imitated manufacturers for phishing assaults for Q1 2020.
