I'm trying to help a friend who got her iPhone locked for ransom through the "I lost my iPhone" feature.
The screen is locked and says "Dlya polucheniya parolya, napishite na e-mail: helpicloud3@gmail.com".
I got her to change her password and use the "sign out of all browsers" option on AppleID so now she should be the only one with access to it.
I thought that was over, but when she accessed the "Lost my iPhone" page to unlock the phone it said "Device is offline". We checked and the iPhone seems to have WiFi off and says "SIM locked" in the status bar, upper left.
I looked around for a solution, but found nothing. I searched the ransom message over google (https://www.google.it/search?q=Dlya+polucheniya+parolya%2C+napishite+na+e-mail:+helpicloud3%40gmail.com) and found 3 sites: two in Russian (still have to check them) and one in English (http://kilishek.com/index.php/2016/05/14/friday-13-my-apple-id-was-hacked/), where someone describes the same exact ransom happening the same exact day, but he had no problem in recovering the iPhone.
Can someone help me?
Edit:
Problem solved: the iPhone's SIM had the PIN activated and this prevented it from connecting to the cloud.

If this iPhone model has a SIM card, try to put it to another phone/iPhone and try to disable SIM Pin.
On iPhone: Settings -> Phone -> SIM PIN -> disable
Then put this SIM again to your friend's iPhone and reboot it. After restart, iPhone should automatically log in to cellular network and you should be able to disable the lost mode using iCloud page.
Maybe your friend should consider using two factor authentication to enable additional protection to iCloud account: https://support.apple.com/en-us/HT204915
