Privacy Emergency Guide: Compromised Account Response

Got hacked? Start here. Step-by-step response for a compromised account, financial theft, or stolen device - in order of urgency.

Privacy Updated May 28, 2026
🚨

Immediate Response Protocol

The following steps should be executed immediately upon identifying a potential compromise.

Phase 1: Stop the hackers

🔓

Hacked Accounts

When you’re locked out of your email or see logins you don’t recognize.

Priority 1

Immediate Steps

💸

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.

Priority 1

Stop the Bleeding

💻

Hardware Compromise

Indications of remote access, persistent malware, or ransomware.

Priority 1

Containment Steps

Phase 2: Address specific attack vectors

📱

SIM Swapping

Unauthorized transfer of a mobile number to a new device

CRITICAL

Technical Risk

A successful SIM swap allows an attacker to intercept SMS-based multi-factor authentication codes, enabling them to reset passwords for financial and identity accounts.

Immediate Recovery

☎️

Voice Phishing (Vishing)

Social engineering via telephone impersonation

HIGH
Common Attack Indicators
  • Requests for credentials, PINs, or secondary authentication codes.
  • Utilization of artificial urgency or threats of legal action.
  • Requirements for non-standard payment methods or remote access software installation.

Mitigation Steps

Phase 3: Long-term remediation

Address the structural vulnerabilities that allowed the incident to occur by establishing a more resilient security configuration.

Frequently asked questions

My account was hacked - what do I do first?
Change the password immediately from a device you trust (not the one that may be compromised). Then revoke all active sessions - most platforms have a 'sign out all devices' option in security settings. After securing the account, check for forwarding rules in email and review recent activity for anything you didn't do.
How do I know if my email has been compromised?
Signs include password reset emails you didn't request, login alerts from unfamiliar locations, sent emails you didn't write, or contacts receiving spam from your address. Check your email's security log and look for any filters or forwarding rules that were added without your knowledge - attackers often add these to silently forward copies of your mail.
What should I do if my financial account was accessed?
Call your bank or card issuer immediately - not through a link in any email, but through the number on the back of your card or their official website. Report unauthorized transactions, freeze the account if possible, and ask for new account numbers. Then file a report with the CFPB and your local police department for documentation.
What is the difference between a data breach and being hacked?
A breach is when a company you use gets compromised and your data leaks - you weren't targeted specifically, you were just in the database. Being hacked usually means someone targeted your account directly, often using credentials from a breach. The response is different: breaches require monitoring and password changes for that service; direct account compromise requires immediate lockdown and session revocation.
Should I wipe my device if I think it's compromised?
For a phone or laptop you suspect has malware, a factory reset is the safest option if you have a backup. Don't restore from a backup made after the suspected compromise date. For most people, the risk is usually credential theft (phishing, password reuse) rather than device-level malware - change passwords first and see if that resolves the issue before wiping.
