The force has received reports that a telephone scam is operating in the county.
The scammers claim they are from service providers, such as Microsoft and TalkTalk, and they need to take control of your computer to fix an issue with it.
The fraudsters then offer you a compensation payment for the problem they have just fixed and claim that they have made a payment into your bank, building society or PayPal account.
They then inform you they have accidently over paid you and ask that you transfer the money via a money sending service to an individual abroad.
Cambridgeshire Constabulary are issuing the following advice:
If you are not expecting a call it might be a scam, even if the caller or emailer says they are from a legitimate company.
Hang up and contact the company back, using contact information you have used before or researched on their legitimate website.
Preferably call them back from another phone.
Do not use the same phone if the caller has suggested you call them back. This is a different scam altogether where they don’t disconnect the phone line. Click here for more details.
Never give the caller remote access to your computer by clicking on any links or opening attachments in emails that have been sent to you.
If you have given remote access to them turn off your router at the mains electric, leave it for 30 seconds and then turn it back on.
Do not give anyone your full password, pin numbers or bank account details. A legitimate company will not ask for any of these.
If the scammer claims they have sent you money to your bank account never send money back. Especially if they ask for it to be paid via PayPal or a money sending service.
Run an up to date anti-virus and anti-spyware program to detect and eradicate any malware and spyware. Alternatively seek help from a trusted vendor.
If you think you have been a victim of a scammer then contact your bank and then report it to Action Fraud on 03001 232 040.
