Reports of ransomware attacks in New Zealand have surged during the past few months with almost $4 million in direct financial loss, according to Cert NZ.
Ransomware is a type of malicious software that attackers use to access the computers and systems to encrypt files, and then demand a ransom to have them recovered. These attacks usually target businesses and organisations.
Between the second quarter of this year, there were more than 1350 cyber security incidents responded to by Cert NZ.
Authorities believe this may be just the tip of the iceberg, with many victims too embarrassed to report incidents.
“Paying the ransom does not guarantee that your files will be recovered and if an attacker sees you are willing to pay, it may also open you up to future attacks,” said Rob Pope, director of Cert NZ.
“If you believe you have been a target of ransomware, isolate your machines by disconnecting cords and router, seek the assistance of an IT provider.”
