Just when Chipotle was getting back on its feet from the food safety scandals, this happens.

The custom burrito chain announced to analysts Tuesday, that they had detected "unauthorized activity" on their payment processing network, and believe they may have been hacked, according to Fortune.

While Chipotle was able to implement security measures pretty quickly to stop the hacker, data on sales between March 24th and April 18th may have still been compromised, so anyone who bought Chipotle in that time frame should be wary.

Chipotle later released a public statement on the activity, encouraging their customers to check their payment cards:

"Consistent with good practices, consumers should closely monitor their payment card statements. If anyone sees an unauthorized charge, they should immediately notify the bank that issued the card. Payment card network rules generally state that cardholders are not responsible for such charges."

Chipotle is conducting an investigation with law enforcement and cyber security firms to determine exactly what happened, and will notify affected customers as everything gets straightened out and the investigation on their end is resolved.

In the meantime, if you've had Chipotle recently, you might want to keep an eye on your credit, or debit card activity. Better to be safe than sorry when it comes to hacks.
