The group claimed that it also stole several pieces of source code that were stored on the compromised computer.

News of the breach was first reported today by The Hacker News (THN) which published screen shots showing samples of the allegedly compromised data, which include names, email addresses, phone numbers and other data stored on the server.

THN said the Pakistan Cyber Army contacted it earlier today to inform it of the attack on the Acer system and the theft of personal data.

Lisa Emard, director of media relations for Acer America, said the company's U.S. operations have no information on the breach. The company is trying to get a response to the PCA claims from its European officials, she added.

The breach comes as Acer, the second largest manufacturer of laptop computers in the world, faces increased scrutiny of its financial reporting practices.
