Southlake-based Sabre investigates breach of travel systems

Southlake-based Sabre Corp. acknowledged that it’s investigating a “cybersecurity incident” but isn’t sure whether any information was stolen.

In a quarterly filing with the Securities and Exchange Commission late Thursday, the travel technology firm said it recently became aware of an incident involving several servers managed by a third party.

The company said it is investigating. “At this time, we are not aware of the compromise of sensitive protected information, such as payment card industry data or personally identifiable information, in connection with this incident,” the filing reads. However, the company said, there is a risk that such information was compromised.

The development was first reported by Bloomberg News.

Fort Worth-based American Airlines, which uses Sabre, says it worked with outside cybersecurity experts to check its digital information and found no evidence to suggest a breach.

“There is also no evidence that customer data may have been compromised,” the company said in a statement.

Several recent high-profile cyberattacks have put corporate technology experts on edge. The attacks have included one against the federal government’s personnel office and another against insurance company Anthem Inc.

Citing people familiar with the investigation, Bloomberg reported last week that China-backed hackers breached computer systems at United Airlines in May or June. A United spokesman did not deny the report but said customer information was secure.
