Verizon Wireless has sued Hewlett-Packard\u2019s (HP\u2019s) private investigators for faking their identities to obtain other people\u2019s phone records, a practice known as "pretexting."In a case filed Thursday in U.S. District Court in New Jersey, Verizon asked a judge to award it damages payments and to block the defendants from gaining any more records.Verizon said it did not know the investigators\u2019 identities, but defined them as "John and Jane Does" who were retained by HP in 2005 and 2006 to investigate confidential information leaks from HP\u2019s board of directors, according to the lawsuit.Those people obtained private information about Verizon Wireless customers by using pretexting calls to gain access to the company\u2019s protected computers and data storage facilities. They then sold that information. Both actions violate the national Computer Fraud and Abuse Act, Verizon said.The scandal has already forced Patricia Dunn to resign as HP board chairwoman, and sparked investigations by the California attorney general and the U.S. House of Representatives.In court papers, Verizon described how a woman called Verizon customer service on May 17, 2005, asking to see phone records for an HP director. She called back three days later, arranging to block text messages to that phone and logging on to the person\u2019s online account. Then, on Feb. 1, 2006, someone called Verizon customer service again, asking for the number of a second phone on that account. Later that day, the person logged into the account again and changed the password, this time from a computer with a different IP address.The next day, someone called Verizon and asked to see call records of the director\u2019s spouse. Verizon workers grew suspicious and placed a warning on the account. Someone called again on March 1, offered the spouse\u2019s Social Security number and asked for the mobile phone number. Already wary, Verizon workers called the mobile phone and found that the customer\u2019s voice mail did not match the caller\u2019s voice. When someone tried again to access the records on March 14, Verizon workers refused.Verizon hopes the lawsuit will help restore its customers\u2019 confidence in the security of their records, saying that its reputation has been harmed by the spying."Verizon goes to great lengths to protect confidential customer information," including training its customer service representatives to identify the schemes used by illegal data brokers, the suit said.Despite those precautions, the HP investigators used "fraud, trickery and deceit" by making pretexting calls to Verizon representatives to gain unauthorized online account access, the suit alleges. Verizon said it will update the suit once it learns their identities.-Ben Ames, IDG News Service (Boston Bureau)Keep checking in at our HP Spying Scandal page for more CIO.com coverage of this unfolding story.Check out our CIO News Alerts and Tech Informer pages for more updated news coverage.
