Experts are speculating that a recent breach of a 100 million credit card transactions could be the largest credit card breach in history. The reported number of potential victims is more than twice the approximately 45 million credit card transactions that were breached by criminals that hacked credit card processing systems of TJX, the parent company of TJ Maxx, Marshalls and other popular retail stores.

Heartland Payment Systems, a large credit card processor based in New Jersey, announced this week that hackers had breached the company's computer network and potentially gained access to customer information related to approximately 100 million transaction processed by the company. The breach included information that would allow criminals with the proper knowledge and equipment to create duplicate credit cards.

While Heartland is based on the east coast of the United States, the company processes transactions for 250,000 business located across the country and of all sizes and types.

There is no information available regarding notification of potential victims, although most states do have strict laws that require businesses to disclose data breaches to consumers. Businesses also commonly provide free access to a credit report monitoring service to victims for some period of time following a breach. There is no word yet whether Heartland will be providing free credit report monitoring to victims.

As always, our advice is to act quickly if you believe you or your family may have been a potential victim of this breach. We recommend that consumers review their credit reports in an effort to identify any suspicious accounts or activity. Many credit report monitoring services offer free access to your credit reports and scores when you sign up for a free trial (read our reviews and comparison of credit report monitoring services to learn more). It is also a good idea to keep an eye on your credit card statements and alert your credit card company of any charges that you believe may be fraudulent.

Additionally, we recommend signing up for an identity theft protection service, such as Trusted ID or LifeLock, that can help prevent new fraudulent financial accounts from being opened in your name.
