Reminds me of the time when I got a random call from some company that claimed that they detected my system has a virus on it and the only way to fix it was to have me give them remote access to the system.
They were talking about my own home PC, yet called to tell me this while I was at work on my work PC. lol (call was done over my personal cell)
Woman asked for information so I returned requesting information, while on the phone I asked them what Virus scanner do you see me using, they said Norton, wrong answer #1 I use Kaspersky, I researched the number of the phone call, Wrong answer #2 came up as a scam number, I requested an address to the physical location they work out of, checked the address in Google, came up with a random open field in Colorado. So as I am talking and gathering information I decided time to spill the beans. I said " Sure I will cooperate, this issue needs to be fixed now, but first let me ask you something. "
I continued, " So, you said this is my home PC and you just caught this on your scanners,"
they replied " Yes that is correct"
I continued, " Well I'm not at home right now and currently my PC is turned off and, so it is impossible for you to know what is going on with it right now. You said I was using Norton Anti-Virus, which is completely incorrect and I am not revealing the program I do use to you. The number you used to call comes up as a random generated number and doesn't link to anywhere and the address you have given shows a random field in the middle of Colorado where there is no building present on the location."
I received no response, so I kept going
" Well its obvious I have found a scam and BTW, you are requesting information from a Gov. employee that holds a high end security clearance and has ties with the several federal law enforcement agencies including DCIS (this is actually true) and I am currently recording this call and documenting everything and it is currently being forwarded to both DCIS and the FBI (I didn't really do that though), so without further discussion is there anything else I may help you with?"
Their response a swift click and never heard from them again. I did all this in front of my boss(now former) and she about died laughing and how I handled the call.
