Like a ghost in the machine, unknown callers can spook anyone, but without specific reports on this number, it's tough to pin down the threat. Stay cautious with unsolicited calls—hang up on anything fishy, never share personal info, and register on the Do Not Call list to cut down on junk. Use apps like Truecaller or Nomorobo for screening, and report suspicious numbers to the FTC at donotcall.gov. If it's persistent, block it outright. Better safe than sorry in this dial-a-scam world.
The caller didn't introduce themselves and seemed to be testing numbers. Nothing useful, just ignore.
