There are lots of individuals who are seeking opportunities to commit fraud. Unfortunately this is much easier in an online environment, where it’s possible to engage with people in different locations and countries.
A common fraud which unfortunately catches out far too many people, is the unsolicited phone call from “Microsoft” or some other official sounding organisation informing you that your computer is generating errors which they can see. The caller goes into some detail to talk you through a variety of actions which demonstrate that there are indeed errors on your computer (these are actually perfectly normal). They then offer to connect to your computer and resolve the problem for a fixed fee, paid instantly by credit card. In doing so, they have access to your computer and also your credit card details. You can guess what happens next, but it’s unlikely to end well.
Clearly these calls are not actually coming from Microsoft, or whichever other company is named. Such organisations don’t call people in this way, and certainly wouldn’t behave in such a manner. The callers are usually based overseas, and have as much connection with the reputable companies that they claim to work for as I do with NASA. Whilst you personally may not be taken in by this fraud, we may all know less technically aware family, friends and neighbours that would. Why not mention this to them and help them avoid becoming a victim of cybercrime?
