Broadband customers in Northern Ireland are being targeted by fraudsters claiming to be their internet provider.
According to the Police Service of Northern Ireland (PSNI), scammers are contacting consumers via telephone and alleging there is a problem with their broadband connection.
The criminal then encourages the person to install a remote desktop client so they can gain access to their computer.
However, PSNI has warned that fraudsters are now going a step further by also calling victims and claiming to offer them compensation for slow broadband speeds.
The consumer will then declare their account details and the fraudster makes it appear as if too much money has been transferred into their account.
Subsequently, the fraudster will call back and encourage the person to refund the overpaid amount, which means they send actual money to scammers.
PSNI Chief Superintendent Simon Walls commented: "Always be wary of any individual that cold calls you.
"Don’t allow any cold caller remote access to your computer. Be especially suspicious of anyone who asks for personal details, money, banking or credit card information via the telephone."
Broadband customers were advised that if they are at all suspicious about a call they receive, they should hang up and phone the organisation that the caller has claimed to represent to check their authenticity.
Chief Superintendent Walls said this call should ideally be made from another telephone, so they can be sure the original caller has not remained on the line.
"Never be pressured into a transaction over the phone," he continued.
"Guarding your personal and banking details is essential. Never disclose them to any unauthorised person or allow anyone access to them via your computer."
