China National Electronics Import and Export Corp. (CEIEC) Saturday refuted reports that its systems had been hacked and documents obtained posted online.

The reports are "totally groundless, highly subjective and defamatory," the Beijing-based company said in a statement on its website.

"CEIEC reserves the right to take legal action against the relevant responsible individuals and institutions," it said.

The statement was responding to foreign media reports that claimed CEIEC's internal networks had been hacked and documents exposed.

A hacker who goes by the name Hardcore Charlie told foreign media that he had broken into the computer system of CEIEC by cracking key email passwords.

The hacker had posted documents online ranging from U.S. military transport data to internal business memos on several file-sharing sites. But the authenticity of the documents could not be confirmed.

According to CEIEC's website, the company, founded in 1980, focuses on three major sectors -- business solutions integration, overseas engineering integration and defense electronics system integration.
