Police, NetSafe and Consumer Affairs have recently received reports from home internet users of their computer being locked out and a warning screen appearing which suggests the New Zealand Police requires a fine to be paid for copyright infringements or for downloading pornography.
This new form of computer Trojan is designed to scam you into paying the ransom money so your computer is unlocked – New Zealand Police has nothing to do with this malware and you should not pay the ‘fine’.
How are users affected?
Ransomware is a type of malicious software, or malware, that locks a computer and shows a warning demanding the user pay fine to unlock their computer.
The scam angle is the use of the New Zealand Police logo which is designed to scare you into paying the fine to get your computer working again
