Empty silence on the line from an unknown number often signals automated systems probing for active phones. Without specific reports, treat calls from unfamiliar area codes like this with caution—hang up immediately and avoid sharing info. Enable call blocking on your device or through your carrier to filter out robocalls. Register with the Do Not Call list for some protection, though scammers ignore it. If suspicious, verify any claims directly with official sources using known contacts, not callback numbers provided.
A shady financial services pitch that promised high returns with no risk—definitely a scam.
