Ignore short rings like this one—they're classic scam tactics designed to spark curiosity and prompt a callback, often leading to premium charges or more harassment. Block the number immediately on your phone to stop future attempts. If you're unsure about any incoming call, let it go to voicemail; legitimate callers will leave a message. Enable caller ID apps for better detection, and report suspicious patterns to your telecom provider or authorities like the FTC. Staying vigilant keeps your info safe without unnecessary stress.
The call lasted just three seconds before cutting off, a clear sign of a suspicious pattern intended to make you return the call—avoid it.
