Tech support scams - by phone!
I thought these sorts of scams had died a death years ago, but our Accountant called me this morning saying he got a phone call at home last night. Basically he got a call from someone calling "on behalf of Microsoft" warning him about something someone in his house had downloaded onto their home computer, and started trying to get him to do some diagnostics. He very quickly smelled a rat and hung up, but he noted down the caller's number (01274 900113) and when I searched online for it this morning the first hit on Bing was this:
Fake tech support call scam – supportonclick, systemrecure and logmein123.com
It seems that had he stayed on the call they would have had him use a remote support website, then tried to charge him for the privilege.
Seems like this one is pretty active at the moment, so may be worth warning your staff. Luckily I've just finished a training round for most of our teaching staff where I covered exactly this sort of con, but I was surprised to hear that they are still going now that most phishing is done by email.
