This ransomware family is known for being hosted on arbitrary websites and circulated on online forums
Microsoft has discovered mobile Android ransomware called AndroidOS/MalLocker.B that has been evolving non-stop.
It evades many available protections and registers a low detection rate against security solutions, and blocks access to devices by displaying a screen that appears over every other window, such that the user can't do anything else.
"This ransomware family is known for being hosted on arbitrary websites and circulated on online forums using various social engineering lures, including masquerading as popular apps, cracked games, or video players," Dinesh Venkatesan from Microsoft Defender Research team said.
Microsoft has also advised users to avoid downloading apps from unknown sources.
