In order to be widespread, this ransomware uses two main types of methods. The first one is used for it’s initial infections, which accounts for more than 70% of infected devices in the US. This is reported to be a fake Photo viewer app which the victims download, believing it is a legitimate one. To get you to download the app, the virus would send a malicious app, with a message similar to the following:

“Someone made a profile named – Luca Pelliciari – and he uploaded some of your photos! Is that you?”

When the victim is tricked into opening the malicious URL, it immediately downloads the app on the computer of the victim.

This is the main reason why if you encounter the Koler FBI ransomware, you should immediately plug out your SIM card(s) from your device.
