good evening. and tonight, a new break in a case involving a massive invasion of privacy for some big stars, ip colluding jennifer lawrence and kate upton. hackers broke into their account, stole nude pictureses and leaked them on to the internet. now, the fbi is son the job. whether they catch the bad guys or not, this whole thing exposes how vulnerable or most private information can be. and tonight, abc's rebecca jarvis with the investigation and the simple things you can do to protect yourself. >> reporter: from jennifer lawrence to kate upton, it is what could be the largest breach of privacy, racy celebrity photos in history. the fbi telling abc news, it is investigating exactly how it happened and who is behind it. more than 100 of hollywood's

leading ladies accounts' allegedly accessed, photos stolen and leaked on to underground message boards sunday night. now, the pictures and the response from hollywood going viral. >> let's have a big hand for our very first volunteer, katniss everdeen. >> reporter: a spokesperson for "hunger games" star, jennifer lawrence, calling it a violation of privacy. telling abc news, the authorities have been contacted and will prosecute anyone who posts the stolen photos of jennifer lawrence. model kate upton's attorney also confirming the authenticity of the pictures and promising legal action. while some have denied the pictures are real, like "problems" singer, ariana grande, legal experts say to expect bigger battles ahead. >> this could be an uphill battle for the celebrities. first, you have to find the person. that's the toughest battle. secondly, where did the photos originate? who took the photos?

who uploaded the photos? that's a big part of where this case actually happens. and if this person is out of this country, you have direction over that person? >> reporter: how does something like this happen? tonight, apple revealing it was not a breach in any of their systems. including icloud. but instead, a very targeted attack on certain celebrity accounts, including their user names, passwords and security questions. >> what's your mother's maiden name? the name of your first pet. when you talk about a celebrity, you can probably get this information from their wikipedia wage. >> reporter: deep, underground network of hackers are all over the internet. searching for this type of material around the clock. and profiting from the brazen sale of celebrity photos like the ones involved in this breach. these underground contests that are going on, you know, in places like message boards, they almost use it as a mark of honor

to find this material. >> it's a race to the bottom. >> reporter: chris is the ceo of insight security. his firm is hired to protect v.i.p.s. and says it's the kind of thing he deals with regularly. one of his major concerns is that these pictures could be used to blackmail or extort the celebrities. tell me about some of the situations you have found yourself and your clients in. >> so, the high-profile people who we help with their security have a lot of concerns over privacy. we'll try to feed information to the internet which is neither innocuous or misleading to help people maintain their privacy by making it more difficult to find personal information to them. once something is on the internet, it's very hard, if not impossible, to take it off. but one successful strategy to try to push it down to make it harder to find. >> reporter: but it's not just the rich and powerful. the breach of privacy is also raising major security concerns for the rest of us. is anybody really safe? >> the quick answer is no.

if there was one piece of data, which is available digitally, which a large number of very competent and motivated hackers want to get to, eventually they will probably get to it. >> reporter: that's because it appears that some of the stolen material came from cloud storage accounts. servers that store all of our data, from our e-mails to our pictures. even if they're deleted from our phones. often times, they've already been uploaded to the cloud and continue to exist. >> hello. and welcome to joy of sex. >> reporter: a consequence played out in the recent movie "sex tape." >> it went down to the cloud. >> you can't get it down from the cloud? >> nobody understands the cloud. it's a mystery. >> reporter: if you use dropbox, google, apple or facebook, your data is in the cloud. how can you protect your own photos and information on the internet? use unique and separate passwords for all your accounts. enable two-step verification on

all of your apps. first, your user n name and password, and a randomly generated private code, sent to your phone via text message. and accept those software update notifications. they arm your smartphone with the latest security protection. the report for those in hollywood not involved in the breach. >> are you kidding me? >> reporter: "girls star," lena dunham, tweeting the way you share your body must be a choice. support these women and do not look at these pictures. so, what exactly is next for the celebrities caught up in this computer screen drama? >> i think particularly jennifer lawrence and kate upton have done a smart thing. most of the time, when something that is completely unexpected happens to you. and a pretty jarring and awkward thing, the first thing you want to do is not tell the truth and say, it wasn't me. they did a smart thing by saying, this was me. and i'm going to sue whoever i

can sue. they should sort of keep their heads down and keep working. but they're doing a good job. >> reporter: i'm rebecca jarvis, for "nightline" in new york. >> our thanks to rebecca jarvis. for more tips how to protect yourself online, check out abcnews.com/"nightline." coming up next on the show, as children here in america head back to school, where would the kids who are being forced into labor? abc's david muir, with extraordinary reporting on the youngest victims of i.s.i.s. and the other horrors of syria. ever since we launched snapshot, my life has been positively cray-cray. what's snapshot, you ask? only a revolutionary tool that can save you big-time. just plug it in, and the better you drive, the more cash you'll stash. switching to progressive can already save ye $500. snapshot could save ye even more. meat maiden! bringeth to me thine spiciest wings of buffalo.

welcome back. on this day when the world is

recoiling in horror at the news of yet another american journalist, steven sot lof, reportedly beheaded by i.s.i.s., it's worth remembering that there are millions on the run from i.s.i.s. and other terrorists in syria and iraq, including hundreds of thousands of innocent children. and abc's david muir, who has just taken over as the anchor of "world news tonight" is just back from the syrian border where he did extraordinary reporting. welcome to the "nightline" set. >> this was really something. as millions of children go back to school, there is an urgent crisis around the world. children that get up for work, 7, 8, 9. their parents once teachers and engineers. the middle-class of syria. now, the children are supporting the entire family. tonight, we report on the stolen childhood, nearly 600,000 syrian children, refugees in lebanon. and close to 300,000 children working. the children get hired instead of the adults because those children are paid much less.

it's 6:00 a.m. and we're just three, short miles from the syrian border. we're about to witness what has replaced the school day for a 10-year-old girl named hadija. they wake her. she gets dressed. and in minutes, she's hand in hand with her friend. but there's no school bus waiting. instead, a truck, with children soon spilling over. we board the truck with them. they're not going to school. we're headed to the fields. she points out the way. this way? >> this way. >> reporter: the children, their tiny hands holding on, once from middle-class families in syria. now, they are the ones who support their families. you're going to work on the patatas. yes. 20 minutes on the truck. and soon, we spot them. the idle tractors. the farmers waiting for their little workers. they only hire children here, because they know they can make less the little boys are making

more than the little girls. why is that? >> they say boys are stronger than the girls. >> reporter: this boy, dragging himself through the field. tractors barrel by, dangerously close. this is the new normal for the children here, just over the border from syria in lebanon. and many of them, instead of going to school in the morning, come here to the fields. this is one of the many tractors unearthing another row of potatoes. and you see before the dust settles, the children gathering here with their bags to fill them with potatoes. in many cases, they're now the sole breadwinners for their family. rows of children, and the back-breaking work. but they have not forgotten what their life was once like. do you want to go to school later? you do? she wants to go to school. they spent seven hours a day filling those sacks. is it full yet? wants to put more inside, she's saying? this man, the farmer is telling

her she needs to put more in her bag. and we're talking about 8, 9, 10 years old. >> talking from 7. >> reporter: 7. >> a lot of the times, from 7 years old. and you're talking about hard bor. >> reporter: and it's nojust the fields. it's the factories, the auto repair shops. in the back of this garage, a boy who fixes tires. we see children selling flowers in traffic. an 8-year-old stepping clear of a motorcycle. my name is david. what's your name? we asked the boy named mohammed, about the little girl across the street selling flowers, too. is that your sister? yes? and we meet a syrian refugee, trying to sell us tissues through the window. she tells us she lost her mother in syria. many of the syrian children get picked up by the police. without parents and paperwork, some of the children are brought here. how many children do you have here now? >> 71.

>> reporter: 71. some as young as 2 1/2 years old. but without any parents, they still have smiles. and they're eager to give us a high-five. all right. will you show me where you play? he grabs my hand to show where they go outside. you need a key. is this where you play? we walk down the dirt path to the cement playground. who jumps the highest? you? we notice her shirt, which reads, little star. but she was ready to sing about a different star. ♪ twinkle, twinkle, little star how i wonder what you are ♪ ♪ up above, the world so high like a diamond in the sky ♪ >> reporter: many of the children cross the syrian border with their parents. their families, fleeing the terror. but as is so often the case, later, some were separated from their mothers and fathers. we don't even know who some of these children are. >> no. we just go by the name they tell

us. some of them think they know a phone number. and we call. >> reporter: there's no answer. >> yeah. that's the most devastating for a child to not know what's happening with their family. >> reporter: ahmed and hoed da are brother and sister. we ask if they remember their home in syria. >> it is a big building. >> reporter: a building. like an apartment? >> like an apartment? >> reporter: we're told they're allowed to play outside here twice a week. but neighbors complain about the noise. they race to pick flowers through the gates. and soon, bring them to us. they are hungry for attention. hungry to play. and soon, it's back inside. walking up the darkened hallway, around the corner, past the kitchen, to their beds. we noticed the paint peeling on the ceiling, on the wall here, we notice two words, love me. this is your bed? and hoda, crawling on her bed, about to finish that familiar song here. ♪ how i wonder what you are

>> reporter: tonight, there is an urgent count on the ground to get a handle on how many children are working. unicef says 300,000 syrian children do not go to school here. we would discover a sliver of hope. some of the same children, after seven hours of hard labor, still with a skip in their step. around this corner, a tiny building. and we could hear their voices. the kids are learning here? unicef, trying to give them the school they miss. and we asked the children, how many came here after work? right down the line, their tiny hands, fresh from the fields. proud of their hard work. 50 potatoes. he points to his back. it hurts your back? a little bit, yeah. >> they come running here. they will be so exhausted from work. but they're excited about coming to school that they run home, grab a sandwich and run to

school. >> reporter: you're trying to save at least part of their childhood. >> yes. >> reporter: do you fear this is a lost generation? >> this is the big fear with everyone, particularly the children. the fear of the lost generation. and it exceeds boundaries in lebanon. it's in syria, it's in jordan, it's in iraq. >> reporter: this is syria. what you remember of syria. this is your neighborhood? she draws her old street. she remembers a restaurant. did she eat at this restaurant? yeah. she remembers it. the flowers, the cars, the boys and girls who once played outside. how many of you want to go home? it does not take them long to answer. instead, we return to the tents, where they all began their day, returning with a song. the farmers in the field, waiting for them again tomorrow. and we want you to know tonight, there are ways you can help.

you can reach one of the classrooms. unicef saying $15 can bring supplies. pencils, paper. you can find the information at abcnews.com/nightline. >> it's striking to watch the faces of those children. so resilient and joyful in the face of advisety. >> this is their new normal. the new lives interrupted. >> on your second day as anchor of "world news," as your friend and your colleague, i want to say on behalf of all of us at abc news, we are so excited about this new era that has begun. and very proud of you. >> thank you. we're in this together. >> we are. thanks for your reporting tonight. we'll be right back with more "nightline." keep it here. ♪ ♪
