Support scam info

Here are some recent (unedited) comments to one of my ESET articles on support scamming.

The latest comments to How to recognize a PC support scam include three particularly interesting comments. The first includes a couple of phone numbers that might be worth investigating. The second indicates an oddity as regards the scammer’s caller ID, and the third (by my colleague Aryeh Goretsky, who has experience in the telephone industry) explains its significance:

  1. We recieved several phone calls today from this same identity, he proclaims himself to be from the national computer security.  I felt scam from the beginning but I wanted to know his ploy, he had already tried to extract info from my teenage son(15) but very computer savey(too many gaming hackers for friends). The caller called w/o giving name but caller id showed (4-905-512-3123) however when told he was being traced, he gave a number (510-314-4990)(person not available). They try to convince you that any caution or failed service history notices are dangerous hackers.  Don’t delete but talk w/ their tech reps and they will tell you what to do.  My oppinion, bad idea.  My neighbor is w/ cyber crimes for our city, I’ll ask his help and have my compuiter checked out by a local reputable source
  2. I got several calls from this weird NODID caller ID wich isn’t what my phone usually displays when I get an anonymous caller id. And today I was home and answered to this guy who sounds like he is from india, telling me he works for PC support and that my computer is sending them online error reports. It seemed obvious it was a scam so I told him to stop calling me because I am not interested in whatever he had to offer. He then asked if I thought it was a sale call, I replied that I think it’s a scam. And he hung up immediately. I looked up pc support on the internet and found this page. They do still try to fish with this scam. My phone number is in east coast Canada
  3. Hello Jonathan, I wonder if your Caller ID might have displayed “NO DID”? D.I.D. is an abbreviation for “direct inbound (or inward) dialing” and is a term used in telecommunications to refer to phone line assigned to a specific device. In this case, I have to wonder if the scammer who called was had hacked into some company’s VoIP phone system to steal phone service for their calls, and this was displayed as a result of that action.
