i imagine that's why sony took so long to announce this. they were probably hoping to find better news. they were probably hoping to find evidence that that information wasn't accessed. now they've brought in an outside company i expect they'll know a lot more than they do now eventually. of course, they may know more than they're telling us now. >> suarez: the playstation system has been down for over week, disappointing a lot of people who are frequent users. does that long-term shutdown tell you something about the seriousness of the breach? that they're not patching it but rebuilding the whole network? >> absolutely. it's a really radical measure to take. it's surely going to cost them a lot of money and a lot of fan loyalty. there are people that aren't even going care about the breach itself who are just going to be extremely angry they were denied access to the playstation network for so long. so it's bad news all around. if this had just been a casual intruder, a recreational intruder, some kid working from his bedroom i doubt they

hear more tomorrow when sony representatives appear at a house hearing. in the meantime, the company's online service is still not fully restored, and the costs are staggering. sony says it may end up spending more than $170 million related to the attack, including online security and protecting its customers. that's what makes hacking different from other crimes. around the world, when businesses are threatened, mere vandalism can become extortion-- "pay me, or i'll break your windows, destroy your stock, burn down your store." but for all the real damage done with hacking, businesses can't make sales, you burn up staff time cleaning up the mess. there's no apparent cash flow back to the hacker. >> reporter: in london today, an international conference heard warnings that the problem is growing exponentially, with up to 70,000 malicious programs designed to disrupt systems being discovered every day. president barack obama has already made cyber security a priority, and u.s. government agencies say they've gotten more aggressive about tackling cyber crim

also today, sony said it is fully restoring its playstation network in the u.s., europe, and parts of asia. hackers stole customer data from the network back in april and forced sony to shut down the service. those are some of the day's major stories. now, back to jim. >> lehrer: former massachusetts governor mitt romney formally entered the 2012 presidential race today. he came with a nominal frontrunner status, as well as some lingering questions. judy woodruff has our report. >> woodruff: the former massachusetts governor kicked off the official start to his 2012 campaign in stratham, new hampshire, at a farm owned by a couple of his supporters. romney said his top priorities as president would be jobs and the economy. >> from my first day in office, my number one job will be to see that america once again is number one in job creation. ( applause ) >> woodruff: this marks romney's second run at the white house. he was competitive in 2008, winning 11 primaries, but dropped out that february. with the economy expected to be the main focus of this election, romney is trying to sell h

against some of its own business partners-- other device makers that use android software, such as sony ericsson. but google can gain another important asset in the deal-- control of motorola's more than 17,000 patents, plus another 7,500 still awaiting approval. we look at the deal and the mobile tech business now, with staci kramer, editor of paidcontent.org, a web site that covers the economics of media and technology; and charles golvin, a principal analyst for forrester research. charles golvin, start with the issue of manufacturing phones and other devices. how does owning a company does that fit into google's larger strategy? >> well, it's mainly about competing better with apple who owns the entire soup-to-nuts control of the software, the hard wear, the content that they sell and the channels that they distribute the devices through. google, because they license their software to manufacturers like sam sung and lg, they don't control those pieces, the hardware pieces. they just control the software pieces so acquiring motorola gives them more of that top-to- bottom control over

we've seen a lot of attacks, hacking attacks into sony, nintendo, pbs. we've seen a lot of these... the vulnerability of information that resides on the internet. when i say resides on the enter, i mean it resides on servers. you don't know where they are but large data forums all over the country around the world where there are bits and pieces, the bits, i should say, of the music that you have. the videos that you have. the bits, the actual digital pacts. they reside in these places that you don't really have so much control of. when you make this decision to switch to cloud-based applications, it's much easier, more convenient and often much cheaper. but there often is the... there is the consideration of afraid-off perhaps in that there may be less security involved. it's much safer when you have your information on your own computer. but only you can access. than on the internet. your privacy is also perhaps in question. more people, more companies have access to what you're doing. they can see what you're doing online. >> suarez: i know young people. i'm not going to use any
