Sony Falls After Reporting Data Breach on 101 Million Users

May 6 (Bloomberg) -- Sony Corp., said to be subpoenaed by New York over data breaches of its PlayStation Network, declined to the lowest level in more than a month in Tokyo trading after raising the number of accounts that were compromised.

The stock dropped as much as 4.5 percent to 2,211 yen, the lowest intraday level since March 15. The shares were traded 4.2 percent lower as of 9:26 a.m., while Japan’s benchmark Nikkei 225 Stock Average slid 1.8 percent

The maker of PlayStation game consoles was attacked by computer hackers between April 16 and April 19 and the intruders may have gained information on 101.6 million users of Sony’s online services for games, music and films. The company was subpoenaed by New York’s attorney general over the data breaches, a person familiar with the probe said.

Sony is offering customers of its PlayStation Network and Qriocity online services a year of free identity-theft monitoring. The company is in the final stages of testing the PS Network before restarting it, Patrick Seybold, a spokesman for the Tokyo-based company’s video-games unit, said today in a blog post.
