Sony cranked up its video game networks over the weekend starting with the Americas after an unprecedented breach led to the theft of personal information from more than 100 million user accounts.  But experts continued to  criticize the Japanese electronics giant for failing to plug other potential holes in its vast global network.

Using little more than a web browser, a search engine and a basic understanding of security systems, one researcher found more than five entryways into Sony’s systems in the United States and elsewhere shortly after the story went to press. ”"Sony still has several external security issues that need to be addressed,” John Bumgarner, chief technology officer for the U.S. Cyber Consequences Unit, tells Reuters’ Jim Finkle.

Bloomberg weighed in on Monday to lay out how hackers of Sony’s networks and others have Amazon.com’s cloud computing services to launch attacks, citing unnamed sources.

Kazuo Hirai, Sony’s No. 2, has played a prominent role in dealing with the crisis. Whether Sony recovers from the drubbing to its brand will decide if he takes his place as leader of the company.

We’ll have some tips for Hirai later this week at the  Reuters Global Technology Summit in New York and Paris, where we plan to ask a broad range of tech chiefs how they would fix the one-time mighty electronics giant.
