Phishing phone calls claiming to be Microsoft technical support

People in Finland have recently received a lot of phishing phone calls claiming to represent Microsoft technical support. The calls may come from a Finnish or a foreign number.

During the call, the caller will try to persuade the person on the other end to install various software on their device. The caller may claim that the computer, tablet or smartphone has a security issue. This type of scam is commonplace around the world.

Never give your username or password to anyone

Keep in mind that these kinds of phone calls are always scams. Microsoft will never call users unless they themselves have requested support. Never give your online bank user identifiers or passwords to anyone who contacts you. Anyone asking for this information is always a scammer.

Scammers want you to install applications in order to gain access to your device, online bank user identifiers and payment card details. Scammers may also ask you to send a copy or photo of your ID card, such as passport. Scammers use this information to transfer money from accounts or make charges on your card.

What to do if you suspect that you have been the victim of a scam call

If you have received this kind of a phone call and installed an application on your device, here’s what you should do:

  • Deactivate your online bank user identifiers and all your payment cards by calling OP Customer Service at 0100 0500.
  • Outside service hours, deactivate your user ID by calling OP Deactivation Service at 0100 0555 (24/7). Be sure to also call our Customer Service during service hours to report the incident.
  • When calling, tell that the phishing phone call was made by someone who claimed to be from Microsoft technical support and that you installed new applications to your device at the caller’s request.
  • Check if there are any charges on your account or payment card that you don’t recognise. Report these as well when calling our Customer Service or Deactivation Service.
  • Clean your device or have a professional do it and delete the applications you installed because of the scam.
  • Don’t start using your new online bank user identifiers until the device has been cleaned.
