🚨 Real-Life Incident: SIM Swap Attacks

In 2019, Twitter’s former CEO Jack Dorsey had his account hacked—not through Twitter, but through his phone number.
Hackers tricked the telecom provider into transferring his number to their SIM card.
Result? They gained access to SMS-based 2FA codes and hijacked his accounts.

How to stay safe:

🔒 Avoid using SMS for two-factor authentication—prefer authenticator apps or hardware keys

📞 Add a PIN/password to your mobile carrier account

📲 Monitor for sudden “no service” signals—it might mean your SIM was swapped

🚫 Don’t overshare personal details online (birthdays, addresses) that can be used for verification

Your phone number isn’t just digits—it’s a key to your digital life. Protect it.
