Malware known as Kolers or policeware takes over your Android with a warning that claims you are under surveillance by federal agents for alleged criminal activity. The malware demands a ransom of $300, paid via MoneyPak, to unlock your phone. Koler doesnt scramble any of your data or exfiltrate audio and video as it claims; it merely locks your phone with a pop-over browser window that quickly reappears if you try to get clear of it.”]
