Remote access scams try to convince you that your computer and/or internet has a problem and try to sell you software to fix the problem.
To get remote access, the scammers need to talk to you.
Some scammers try to do cold calling, but the success rate of scamming people is higher when they get called by their potential victims.
For that to happen, they need to find a way to display their phone number online. The most common method is the use of pop-ups.
These pop-ups display an urgent warning message + the phone number of the scammer.
The pop-up can often not be closed.
The scammers will try to talk to you and pretend to be working for a big tech company (e.g Microsoft). Usually they claim that they are some sort of technical support and certified in something.
They will tell you that your device has a virus or something similar and will ask you to give them remote access to analyse the problem and fix it.
After showing you some “serious problems”, they will try to talk you into buying expensive and overpriced software which will “fix” your device. A lot of the software does not even do anything.
Never allow anyone that you don’t know access to your device.
