In May 2015, the IRS experienced a data breach that resulted in unauthorized access to taxpayers' personal financial information. Cybercriminals exploited the IRS website to steal sensitive data, which was then used to claim fraudulent refunds in the names of unsuspecting victims. This incident highlighted the need for robust security measures to protect both individuals and businesses from the growing threat of cyberattacks and identity theft.

How many accounts were compromised?

The breach impacted data related to approximately 100,000 individuals.

What data was leaked?

The data exposed in the breach included email addresses, Social Security numbers, income information, and other personal financial details.

How was IRS hacked?

The organized crime syndicate exploited the IRS website to steal taxpayers' personal financial information by using phishing and spearphishing scams, as well as a Form W-2 theft scheme. These techniques allowed them to obtain sensitive data, which was then used to file fraudulent tax returns and claim refunds in other people's names. The IRS has since taken measures to prevent future breaches, including implementing robust security software, using strong passwords, and consulting security professionals.

IRS's solution

In response to the hack, the IRS implemented several enhanced security measures to protect taxpayers' personal financial information and prevent future incidents. These measures included contacting taxpayers via mail with instructions if fraud was suspected during processing, recommending the use of best practices published by the U.S. Federal Trade Commission, and advising small business owners to stay informed about the latest scams and continuously protect their computers and smartphones. Additionally, the IRS provided guidance for tax professionals on safeguarding taxpayer data and creating action plans in the event of a data theft.

How do I know if I was affected?

The IRS reached out to affected individuals following the data breach. If you believe you may have been impacted but did not receive a notification, you can visit Have I Been Pwned to check if your email has been compromised in this or any other data breach.

What should affected users do?

In general, affected users should:

  1. Change Your Passwords: Immediately update your passwords for all online accounts. Make sure the new passwords are strong and unique, not previously used on any other platform.

  2. Reset Passwords for Other Accounts: If you've used the same or similar passwords for other online accounts, reset those as well. This is crucial as attackers often try using stolen passwords on multiple sites.

  3. Enable Two-Factor Authentication (2FA): Activate 2FA on your accounts. Consider enabling this additional security feature on all other important online accounts to significantly reduce the risk of unauthorized access.

  4. Monitor Your Accounts: Keep an eye on your accounts for any suspicious activity and report it immediately to the respective platform or financial institution.
