Cold callers pretending to be from Microsoft offering to remove viruses from computers are sending shivers down the spines of technology experts.
Microft and NetSafe have joined forces to issue a joint warning against the scam which cost at least one Kiwi $5,000.
The scam, in which the caller offers help by gaining remote access to computers for payment, has been going for years but has seen a resurgence on the back of the release of Windows 10 in July.
The scam is built on lies. Microsoft never cold calls customers. There’s no way the software giant could know a machine was infected with a virus. Would you want to give your credit card details to someone like that?
NetSafe executive director Martin Cocker said, in a statement, that the pattern of scamming was not new. The scammers use the Microsoft brand as the company was trusted.
“Unfortunately some people believe the calls are genuine and are led to believe they are doing the right thing by handing over private passwords or details. They can find themselves losing money or ending up with a computer infected with viruses or other malware that compromise their security,” Cocker said.
His advice is to hang up immediately and report the incident to NetSafe.
Microsoft NZ marketing and operations director Frazer Scott said Microsoft never cold called computer uses.
“We do not call customers at home saying that we have detected a problem with their computer. We will never ask for passwords or other private details in any forum,” Scott said.
“If you have given someone on the phone access and start to worry, then disconnect the machine from the internet and then hang up and report the incident to us. If you have given any bank details to a caller, then advise your bank as soon as possible.”
Features of scammer calls:
- Overseas caller states they are from Microsoft or a Microsoft certified technician.
- Suggests the victim’s computer is infected and harming others online or that their ISP has identified their system as a problem.
- Will get the computer owner to give the caller remote access using a genuine networking service or website like logmein123 or teamviewer
- They will use the Event Viewer tool on the computer to highlight error messages which are supposedly signs of an infection.
- The cold caller will offer to clean up the infection and/or install security software and provide an ongoing support service costing anywhere up to $500.
How to deal with the overseas cold callers:
- Hang up the phone - engaging with or taunting these companies can lead to you receiving many more calls at all times of the day or night. Some technicians have resorted to threats or abuse to get computer owners to give remote access.
- If you do give access but become suspicious, disconnect the machine from the internet immediately. NetSafe has received some reports of these cold calling companies installing ransomware on the computer to ensure they get paid to unlock the PC.
- If you have previously given remote access, it may pay to check what has been installed on your computer and be certain there is no way for the company to continue accessing your system and files. Consult a trusted local PC technician if unsure.
- If you have paid money to these companies using a credit card, call your bank and discuss your options. If you sent funds via Western Union or another wire transfer service then the money is gone and cannot be recovered.
