United Continental Holdings  (UAL) , the parent of United Airlines, was indicated lower in premarket trading Monday after the carrier said that some of its cockpit security details had been made public.

CBS News reported that a 'Safety Alert' email sent to United employees outlining security procedures "may have been compromised" and told the network that "some cockpit door access information may have been made public."

"The safety of our customers and crew is our top priority and United utilizes a number of measures to keep our flight decks secure beyond door access information," United said in a statement to media outlets following the reports. "In the interim this protocol ensures our cockpits remain secure. We are working to resolve this issue as soon as possible."

United shares were marked 0.84% lower from their Friday close in premarket trading, indicating an opening bell price of $75.77 each against an anticipated gain for the broader S&P 500. 

The security breach comes amid concerns for sensitive data and computer-related security following a spate of so-called cyber attacks that have affected more than 200,000 computers in over 150 countries around the world.

However, in a separate response published by CNBC, United spokesperson Maddie King said the security information was "was inadvertently made public" but not as part of a "breach" in the company's computer systems.

Last week, RealMoney contributor Ed Ponsi, author of Technical Analysis and Chart Interpretations, and managing director of Barchetta Capital Management, said that the "twists and turns in the United saga highlight the importance for investors to remain objective during emotionally charged situations."
