Heritage Foundation data breach containing personal data is available online
The Heritage Foundation this month denied that it had suffered an earlier system breach and the subsequent leaking of internal data. But the organization had to admit that cybercriminals gained access to an archive of Heritage’s affiliated media site, The Daily Signal, dating back to 2022. That archive reportedly contained content of Heritage and non-Heritage contributors’ personal information.
Either way, a Malwarebytes review of the data shows over half a million usernames and passwords.
At the heart of the back-and-forth claims are an alleged breach against the Heritage Foundation that SiegedSec, a politically motivated group, claimed to have carried out on July 2, 2024.
The group said it released the data in response to Heritage Foundation’s Project 2025, a set of proposals that aim to give Donald Trump a set of ready-made policies to implement if he wins this fall’s election in the United States.
The stolen data includes email addresses, usernames, passwords, phone numbers, IP addresses, full names, and may contain other compromised user details.
SiegedSec also claimed to have over 200 gigabytes of additional “mostly useless” data, which they do not intend to release.
The discrepancy in the claims lies in the fact that SiegedSec said it obtained passwords and other user information for “every user” of a Heritage Foundation database. Heritage responded in saying that:
“An organized group stumbled upon a two-year-old archive of The Daily Signal website that was available on a public-facing website owned by a contractor.”
A possible cause for the discrepancy is an earlier cyberattack on the Heritage Foundation in April of 2024 which resulted in a shutdown of the organization’s network to prevent further malicious activity. But the nature of that attack is unclear and it is impossible to say whether any data was stolen.
Some sources, however, have reported that it was in fact a ransomware attack by the Play Group, which means that an attempt to steal data is still a possibility.
Protecting yourself after a data breach
There are some actions you can take if you are, or suspect you may have been, the victim of a data breach.
- Check the vendor’s advice. Every breach is different, so check with the vendor to find out what’s happened and follow any specific advice they offer.
- Change your password. You can make a stolen password useless to thieves by changing it. Choose a strong password that you don’t use for anything else. Better yet, let a password manager choose one for you.
- Enable two-factor authentication (2FA). If you can, use a FIDO2-compliant hardware key, laptop or phone as your second factor. Some forms of two-factor authentication (2FA) can be phished just as easily as a password. 2FA that relies on a FIDO2 device can’t be phished.
- Watch out for fake vendors. The thieves may contact you posing as the vendor. Check the vendor website to see if they are contacting victims and verify the identity of anyone who contacts you using a different communication channel.
- Take your time. Phishing attacks often impersonate people or brands you know, and use themes that require urgent attention, such as missed deliveries, account suspensions, and security alerts.
- Consider not storing your card details. It’s definitely more convenient to get sites to remember your card details for you, but we highly recommend not storing that information on websites.
- Set up identity monitoring. Identity monitoring alerts you if your personal information is found being traded illegally online, and helps you recover after.
