What to do:
- Immediately change all passwords and security/identity questions and responses.
- Start with the financial services you use first.
- Use a password manager and never use the same password for 2 sites, or reuse passwords.
- Contact companies, including banks, where you have accounts as well as credit reporting companies.
- Cancel and destroy compromised credit cards, apply for new ones.
- Check to make sure the software on all your systems is up to date.
- Run a scan to make sure your system is not infected
- Observe if your system is acting suspiciously.
- If you find a problem, disconnect your device from the internet and perform a full system restore.
- File a report with the police if you believe there was a financial crime committed or identity theft.
- Raise awareness and tell your friends – maybe this will help one of them to avoid this situation.
Why do it?
The objective is to identify and contain the breach, and then prevent future breaches. It is a long process, but you will be stronger for it.
