What should I do if someone shared my email and phone number without me connecting them?

In the U.S., your email and phone number might be out there due to old data leaks—it’s alarming, but not uncommon. Try searching for yourself online; you’d be surprised what’s available. Also, if you use LinkedIn or similar platforms and listed that info, it can be easily accessed from there. I’d suggest blocking that person and moving on.

It's definitely unsettling when that happens, but usually, it’s not as serious as it seems. A lot of personal information floats around due to data breaches and syncing contacts without you realizing. Make sure to tighten your privacy settings on Telegram, turn off contact syncing, and check your email account for any unusual login activity. If you don't see any alerts about logins or password resets, you’re likely fine.

Just so you know, it’s likely a random scam. Your numbers can be matched by people using social media or data aggregator sites. You probably aren’t in any real danger, but being vigilant about your digital footprint is a good practice.
