that it's okay for you to get a reward without doing any work. >> it's hurtful to hear that because we've developed systems and structures that are occurring throughout the nation to support kids, that we would be accused of inflating grades. >> reporter: the principal at flowers high school says students are earning changed grades through a program called multiple pathways to success. >> fairfax, montgomery, you can go to other counties and see that they are using the same type of processes in order to help kids. >> reporter: but multiple teachers and guidance counselors are alleging that grades are being changed without students earning the credits in an effort to on boost the graduation rate. the union that represents teachers released a statement that reads in part "we are very concerned that these allegations will have a destructive impact on our school system, a statement that left this teacher who has made t

impact the attack is having on american companies in hospitals, too. >> reporter: as you mentioned, it starts in the ukraine and has now hit some 64 countries including the u.s. it hit a pharmaceutical company, health care provider, food and beverage contributor. what it is doing is basically locking up their computers saying that you are not able to access any of the data unless you pay a $300 ransom. the problem say authorities is that once folks pay that ransom, they still may not get their data back. the fix for this is actually fairly easy. just upyou can date the latest security software and folks at home should also do this because while the ransome wear attackers are going after big corporations, next they could focus on personal executers. so good advice for us all to take. >> so do we know who is behind the cyberattack or what their motives are? >> reporter: authorities don't know who is beh

believe it's probably somebody overseas working on this since it started there. but the motive seems to be apparently money. they are demanding $300 in ransom from every corporation and while that amount may seem nominal, it is actually quite lucrative when you tally up all the folks that people are going after. certainly something the authorities are watching closely. >> miguel almaguer, thanks so much. and this evening we are hearing from the parents of an american journalist who has been held captive in syria for nearly five years. austin tice. he was taken hostage in 2012 just days after his 31st birthday. the former marine and fworngeorn law student was in syria to cover that country's civil war. and aside from this video showing him blindfolded, there has been no claim of responsibility. lester holt sat down with tice's parents who say there is no

>> we had a video that was titled austin tice is alive. it has been confirmed over these last almost five years. >> we wouldn't be sitting here talking to you if we weren't completely positive that austin will come home safely and we wouldn't have a lot of the conversations and meetings that we have if that weren't the case. >> with rising tensions between with our country and the assad regime, there is a new sense of urgency to secure tice's release. we will hear more from tice's parents ahead on "nightly news." high blood pressure, cigarette smoking. there are certain are things we all know can increase your risk of heart disease. when we come back, the extra risk for women that you may not know about. guns, cash, all sorts of things taken by criminals because you don't lock your doors. local police using a new technique to sa guard your fe

the ground right now in iowa, however that storm won't bring us storms, it will actually help to usher in the warmer air as it makes its way in. you can see the canadian air right there and then the warmer air out of the west. what we've had is the jet stream going into canada and then bringing that cooler air down across the eastern portion of the nation. but now the heat will begin to move back in and the hot weather wants to remain. i think we have 90 # degrees or better for the next six days at least. so we will have to wait with and see about that. but you the heat wave coming. heat index near 100 especially on on friday and saturday. i think those will be the two hottest days. sunday awfully muggy as well. tomorrow 91, here comes the heat. not too humid. so it will be a comfortable 91. we've had a koourm dcouple days. a pool will be the great place. up to 90 around the 4:00 hour. the pools though starting to get a little on the warmer side. tomorrow you will want to be a cool
