For nearly a decade, hackers enjoyed widespread access to the corporate computer network of Nortel Networks Ltd., a once-giant telecommunications firm now fallen on hard times.

Using seven passwords stolen from top Nortel executives, including the chief executive, the hackers—who appeared to be working in China—penetrated Nortel's computers at least as far back as 2000 and over the years downloaded technical papers, research-and-development reports, business plans, employee emails and other documents, according to Brian Shields, a former 19-year Nortel veteran who led an internal investigation.
The hackers also hid spying software so deeply within some employees' computers that it took investigators years to realize the pervasiveness of the problem, according to Mr. Shields and Nortel documents reviewed by The Wall Street Journal. They "had access to everything," Mr. Shields said of the hackers. "They had plenty of time. All they had to do was figure out what they wanted."
According to an internal report, Nortel "did nothing from a security standpoint" to keep out the hackers, other than resetting the seven passwords.
Nortel's breach offers a rare level of detail about a type of international corporate espionage that is of growing concern to U.S. officials. A U.S. intelligence report released in November concluded that hackers operating from China—both government-affiliated and private-sector—are the world's most "active and persistent" perpetrators of industrial spying. The report cited a number of Chinese attacks, including one targeting Google; the theft of data from global energy companies; and theft of proprietary data such as client lists and acquisition plans at other companies.
The Nortel revelations come as China's vice president, Xi Jinping, arrived in the U.S. for a visit in which China is seeking to promote greater trust between the two countries. Mr. Xi, who arrived Monday afternoon, likely will press the U.S. to expand Chinese access to U.S. high-tech markets at a time when U.S. intelligence officials have expressed increasing alarm about what they say is government-sponsored cyberspying on U.S. and Western companies, particularly in China.
Bloomberg News Nortel's then-CEO, Mike Zafirovski, said people 'did not believe it was a real issue.'
China's government has denied allegations of cyberspying. When asked about Nortel specifically, the Chinese embassy in Washington issued a statement saying in part that "cyber attacks are transnational and anonymous" and shouldn't be assumed to originate in China "without thorough investigation and hard evidence."
Nortel didn't respond to requests for comment. The Canadian company is in the final stages of selling itself off in pieces as part of a 2009 bankruptcy filing.
Nortel was a pioneering maker of the computerized switches and telecom gear that powers much of the world's phone and Internet networks. Nortel equipment (now part of a business owned by Genband Corp.) makes up 45% to 50% of the U.S. telephone switch marketplace, according to Akshay Sharma of research firm Gartner Inc.
As part of its internal investigation, Nortel made no effort to determine if its products were also compromised by hackers, according to several former employees including Mr. Shields, who was a senior adviser for systems security at Nortel. The investigation lasted about six months, and for some of that time involved three staffers, Mr. Shields said, before it fizzled out due to a lack of leads.
Mr. Shields and several former colleagues said the company didn't fix the hacking problem before starting to sell its assets, and didn't disclose the hacking to prospective buyers. Nortel assets have been purchased by Avaya Inc., Ciena Corp., Telefon AB L.M. Ericsson and Genband.
It is possible for companies to inherit spyware or hacker infiltrations via acquisitions, said Sean McGurk, who until recently ran the U.S. government's cybersecurity intelligence center. "When you're buying those files or that intellectual property, you're also buying that 'rootkit,'" he said, using a term that refers to embedded spy software.
Nortel's experience exposes the uncertainties in reporting requirements for company officials who discover that their networks are infiltrated. Companies aren't obligated to disclose a breach to another company as part of an acquisition deal, said Jacob Olcott of Good Harbor Consulting, a firm that advises companies on national-security issues. It is up to the acquiring company to ask, he said.
Since Nortel's stock traded publicly in the U.S., it was required by the Securities and Exchange Commission to disclose "material" risks and events to investors. Many companies are just now becoming aware that cyber attacks must be reported if considered material, said Mr. Olcott, a former Capitol Hill aide who led a committee investigation into public disclosure of incidents like these.
