Hacked? A Step-by-Step Emergency Response
Got hacked? Start here. Step-by-step response for a compromised account, financial theft, or stolen device - in order of urgency.
Phase 1: Stop the hackers
Hacked Accounts
When you’re locked out of your email or see logins you don’t recognize.
Stolen Money
When you see charges you didn’t make or your balance drops. I’ve had this happen with a credit card - caught it within the day, disputed it, and had the money back within a week. Speed matters.
Hardware Compromise
Signs someone else is controlling your device, or malware that won’t go away.
Phase 2: Address specific attack vectors
SIM Swapping
Someone moved your phone number onto their device

Why this one is urgent
Once they have your number, every SMS code goes to them - which means they can reset the password on your bank, your email, and anything else using text-message 2FA. Minutes matter here. Brian Krebs has documented these cases for years if you want to understand how the attack actually runs.
Call your carrier’s fraud line
Voice Phishing (Vishing)
Someone calling and pretending to be your bank, the IRS, or family
HIGH

Common Attack Indicators
- They ask for your password, PIN, or a 2FA code.
- They create urgency or threaten legal trouble to rush you.
- They ask you to pay in gift cards/crypto, or to install remote-access software.
Phase 3: Make sure it doesn’t happen again
Once you’re stable, close the gap that let this happen in the first place so it doesn’t repeat.
