scientists have successfully repaired a faulty gene in human embryos for the first time. the breakthrough could help eradicate inherited diseases — but critics fear it could lead to the creation of so—called designer babies. venezuela has delayed swearing—in members of a controversial new assembly, which would replace parliament and rewrite the constitution. president nicolas maduro has been accused of pushing the country towards dictatorship. meanwhile, the firm which helped organise sunday's election says the results can't be trusted. the brazilian congress has voted not to send president michel temer to face trial for corruption. he's been accused of receiving millions of dollars in bribes from one of the country's top companies. the opposition says the government channelled billions of dollars of public funds to politicians to secure the victory. now on bbc news, it's time for click. this week — the team are in vegas, making faces for cash.

hacking for cash. and free cash! vegas — home to casinos. elvis, sort of. uh-huh. super—fast knot tying. wide, open spaces. limos. the strip. and this week, the largest hackfest on the planet. if there's one week of stuff in vegas that isn't staying in vegas, it's this week's bsides,

black hat, and notorious def con gatherings. this is the week where hackers rub up against law enforcers and everyone peeks over each other‘s shoulders and networks. so, let's get straight into the action. and for our first act of the show, daniel here has got an extra piece of software running, allowing him to hear what's being typed on the other end of a skype call. so how does it work? the software during a skype call learns how your keyboard sounds like and if you later, during the call, type something sensitive, like a password or e—mail, we can understand what you've typed using machine—learning algorithms. this is because each key has a unique fingerprint based on the position of the key on the keyboard. the suggested results from what our victim might be typing

are listed on the screen. it's spotted every word except one, but when asked to choose the words to make the most likely sentence, it's not so on the money. so, this is scott helme. he's notjust our victim, he's also a security researcher who's here to keep click on track with a hacker‘s view of the conferences for the next couple of episodes. hello, scott. hello. what do you think? so, the technology is still quite young. it did take a bit of set—up to make this work but technology advances quite quickly and things that are difficult today will probably be easy tomorrow. we have seen similar things like this before as well. i looked at a hack recently where they could measure the vibrations in a crisp packet to record my voice. so i think in the future, things and technologies like this could be quite bad because it's going to allow people to extract a lot more information from our devices. wow, sobering thoughts. it seems like the hackers are always going to find new and interesting ways to get inside our computers and, of course, the weapon of choice

so far this year has been ransomware, in part because it is so easy to set up. here's spencer with more. i'd kind of assumed that getting hold of a piece of ransomware wouldn't be as easy as searching for it on google and then just downloading it. this man hasjust informed me that i was wrong. so, here is one which is very popular. this one. if i type it into google... then we can just download it straightaway. so this is the code. this is free. that's it? you don't have to go on to the darknet or anything to get hold of it? no.

this is the easy way. 0k, right! so, the code is actually really tiny — it's less than 200 lines of code, and that's for a full piece of ra nsomwa re. i could then change some of that code to specify how much money the malware asks for and the bitcoin address it needs to be delivered to. sure enough, the programme turns all of our sample documents into illegible garbage, which can only be retrieved if the creators — in this case, us — provide the unlock code. i'm slightly depressed at how easy it was to find some ransomware to just unleash onto the world. it's going to get easier in a minute. oh, good! we hop onto a site that will connect me with people who'll set up and run when somewhere for me. this guy here, he'll charge you $125. these guys, they'll give you customer support. also offer you some advice on how to deliver it to people. a full—on service, this? yeah, and via phone, you can talk to this guy over telegram or instant messenger chat as well. if you're too lazy to send this to people, there's another guy who, for a cut, will then e—mail this to your victims as well. "are you a criminal but too lazy to do any work? don't worry, we'll do it for you!"

there are some video adverts like that as well. seriously?! yeah. oh, my goodness! surely you can engage this person in chat and go and get them, go arrest them. these people are quite hard to find. they use software to make sure you can't find where on the internet they are. itjust depresses me so much, though. doesn't it? i'm going to unplug the internet! actually, before you do, spen, there is hope. there are professionals looking out for us, and lara has been to meet the good guys who are at the top of their game. wannacry was a wake—up call. one report suggests one in six businesses in europe and the us were affected. some of them, of course, providing critical care. i'm in newport, wales, at airbus cybersecurity. this is probably not the first thing that you would associate with the company name but here, some top—tier network monitoring is taking place. their clients include the ministry of defence, as well as large airports and power companies, plus many others who can't be named.

wannacry was quite unique by way of ransomware in that once it infected a single host, it actually wanted to go out and look for other hosts that are similar to it within its own network. that's why it spread notjust within the nhs but globally, across many other companies and many other individuals as well. but how about an attack that exploits a vulnerability we've never heard about before? a zero—day attack? typically, the scramble around that is actually obtaining some code and then almost putting it in a sandbox. a sandbox being a place to isolate the issue so it can be played with, understood, and tackled. large organisations may employ companies like airbus to keep the water flowing and the lights on,

but what advice would they give to us as individuals? well, we use cyber threat indicators on our network and this is something freely available to the general user. if you're more tech—savvy, you can utilise this threat intelligence to explain more about current malware threats and trends and understand if you are susceptible to this malware, and if you're vulnerable or running a vulnerable version of a particular software. so that information is out there and i would encourage everyone to use it. but what does all this mean for the future? does cyber security get better at the rate hackers do? there's always an arms race. we get better and then they will follow. and itjust moves further and further into complex areas but rest assured we're working very hard to keep on top of those. so the advice on how to avoid a cyber attack may not have changed in years — make sure you always do your software update, back everything up, and generally be sensible online, but wannacry may have just

frightened more of us into taking action. lara lewington battling the bad guys, which is exactly what this conference, black hat, is all about. the corporate side of this cyber security conference is here in las vegas. but what happens when you've caught a cyber criminal? what if it is a first—time hacker who probably didn't even realise they were breaking the law? well, dan has been to the uk's first—ever rehab for hackers. it was me and two other friends, who were — just a bit of fun. i manipulate people's feelings, thoughts. i started getting bullied. we tried to break into our school's network. we could control people's screens, change passwords. i got arrested for misuse of computer act, 1990, section 3. i can't name the company

but they lost a lot of money. this is definitely a way to get ahead of the curve and to stop anyone from possibly taking a misinformed choice as to the direction of their life. this is the uk's first reboot camp for hackers. the first seven through the doors are aged 16—20. they all intend to change their ways, so we've agreed to keep their identities secret. rehab includes spotting moments when they might be tempted to cross the line of what's legal and what's not. god, that looks tasty. that looks like i could get everyone‘s details. your parents will not have any idea how you do what you do. it will be like magic. solomon gilbert was caught

as a teenage offender. now he's the one giving the lectures, in between tackling cyber crime himself. i was 17 years old. so i was getting drawn into making my own malicious code, making my own exploits, and stealing things like credit card information, data base information. i wouldn't do anything with them but it ended up with me getting kicked out of school and arrested and looked into by the counter—terrorism intelligence unit. what were the key moments that changed your path? everyone in the cyber security industry has one person that they've met that's gone, "well, you're very talented at this. let's move you to do it as a job." cyber security challenge uk has set up a capture the flag competition so that teenagers can show off their skills. and several large companies are here to talk future job opportunities. the uk hasn't got enough people to protect itself.

you know, businesses, the nation, businesses, individual accounts, we all need protecting, and that's why we exist. we need to find these people. these offenders know this is a second chance — one they say they didn't realise they were so well qualified for. i was more interested into the dark side back when i was young. i wasn't really looking at the good side. the dark side was mainly just attacks, attacks, attacks, nothing about defending. well, now i know that it exists, it sounds like something that i'd really, really like to go into because you get the same, like, rush, the same excitement, but you're doing it for fun still, but it's legal and you get paid. so it's like every kind of benefit. did you know you can get money out of an atm even if you don't have a card or pin? what you'll need instead is a drill,

a usb keyboard, some malware on a usb stick, and an intention to break the law. so, in this specific example that we've got set up here, so an attacker has come to the front of the atm, they've drilled a hole in the front. and what we can do now, is, you can see we can access this usb cable. right, so, inside here, there's something that has a usb port. what's inside here? this isjust a normal computer. according to positive technologies' research, more than half of atms still run windows xp. and although the usb port will rarely be this easy to access inside the atm, recent cash machine hacks in taiwan and thailand show that it can be done. i'm sure not many people would expect this to just be a normal windows xp machine.

perhaps not, but it's just a safe with a computer on top. which means that with a keyboard plugged in, it's pretty simple to download and run the malware to, well, show me the money. actual money. actual real money. your malicious software basically says "dispense cash." exactly. 0k. shouldn't the atms be slightly more protected and locked down? you would think that, but it's how you would configure those computers. but we found that they are not particularly secure, so you could put malware on a system that could collect data from cards as well. so that would be information that's held on our cards. so i, as a consumer, if i'm using this machine, it could collect my card data, and that could spread around a whole network of atms.

so, you could use one atm to infect a whole network? that's correct, yeah. one way to protect yourself is to use atms inside bank branches or which are watched over by security cameras. we spoke to ncr, one of the leading manufacturers and the maker of the atm that we hacked. they agree that security threats are becoming more complex and sophisticated and told us: welcome to the week in tech. it was the week that google unveiled its sos alerts feature, which will show where a crisis is taking place. adobe announced plans to kill off flash player from 2020. and a company in wisconsin are microchip being their employees. and the boring company is firmly going against its name, as elon musk posted a video

to instagram of a car going underground on an elevator in los angeles. the tesla ceo's side project proposes building a network of tunnels under the city, which will drag cars, passengers and cargo in super fast moving sleds. and it was a busy week for musk, as he clashed with mark zuckerberg over their views on al. during an informal facebook live, mark zuckerberg said musk‘s claims that al poses a fundamental risk to human civilisation were irresponsible. but musk took to twitter to respond, writing zuckerberg's knowledge of the issue is limited. touche! first it was gone and then it wasn't, as microsoft puts to bed reports that it was getting rid of its graphic programme, paint. people rushed to social media to show their love for the programme, which won't remain on microsoft 10 by default in the future but will be available on the windows store for free. yes, i'm taking commissions! and now you can live

out your pop dreams in ar. not shying away, a chicago—based studio have recreated the classic a—ha take on me video using the ios 11 ar kit. recently, there seems to have been an increase in the number of brute force password attacks. this is where the hacker uses a programme to constantly trying new passwords until they hit the jackpot. in the past, security services have recommended creating as long and complex passwords as possible, never writing them down and changing them often. however, we're only human and we don't have the time or patience to remember multiple strings of letters and digits. to combat this, the national cyber security centre has updated its password guidelines. firstly, don't change your password constantly because this encourages us to use simpler passwords and maybejust add a different number on the end.

and besides, it only protects you from someone who steals your password and then waits three months to use it. you should, however, update your password if you have any reason to suspect a breach. keep your passwords complex, but not too complex. for example, three random words stuck together. this means instead of trying every one of the 200,000 or so words in the english dictionary, hackers have to try every combination of every word, and that is a massively harder task. set up two step authentication for any accounts that you particularly care about. this means the hacker needs to not only have your password but also your phone, to break in. and store your passwords, either on a piece of paper in a safe place or by using a password manager. now, this is either hardware software that generates and stores long, complex passwords for your different accounts. how can you remember 20 or 30 passwords that we frequently use

that are highly secure? with a solution like lastpass, it will create 100 character passwords for every site, that is really, really hard to hack and then layer encryption across it. while security is a really daunting subject and the stakes are high, it can appear quite onerous, but these solutions are really easy to adopt. all you have to remember is one master password and the manager does the rest. just make sure that password is really hard! humans have been using handprints to identify themselves for a very long time. these ones here, the hands across time just outside las vegas, in red rock, are hundreds of years old. they're some of the earliest examples of native americans

showing their identity. kind of like a signature. in recent years we've started to use our hands to identify us again and dan's been finding out how secure they might be. at bristol robotics lab, they're taking an interest in every detail. now, if you're sensitive to flashing lights, look away now. is that more secure, then, than just using your fingerprint? certainly. with a fingerprint, it's a small region of the hand. obviously with this system we're getting the whole surface and that, combined with the vein structure, just add an extra layer of security. do you think this could be spoofed? i think it's unlikely. research recently showed the ability to extract fingerprints or handprints off celebrities from a distance. from photos?

from photos. so, you could use that to generate a 3—d surface but you still wouldn't have the vein structure on the back of the hand. that would be very difficult to hack. in chicago, some people are already using their palm and to pay for things. it's being called naked payment. no cards, cash or phones. palmsecure‘s touchless readers only use infrared lights to take a photo of your veins. iris scanners are also about to emerge from the lab and be used in the real world. from september, tsb will be the first bank in europe to adopt retina scan technology as a way of accessing online bank accounts, although initially customers will need a samsung galaxy s8 handset to use the technology. but is it secure? in may, the chaos computer club in germany posted this video, fooling the s8‘s iris scanner using a photograph and a contact lens. tsb and samsung are hoping

that others won't go to that sort of trouble. at the cylab biometrics center in pittsburgh, they've developed a system that can identify the irises of people moving in a crowd from up to 12 metres away. but if the eyes don't have it, the face just might. back at bristol robotics lab, this 3—d face scanner is using a technique they've developed called photometric stereo. two invisible lights flash at high speed, allowing the camera to capture the orientation, shape and texture of what it sees. so far, it has a 95% accuracy rate but that's good enough to attract some major investment. they are working with cubic which develops the oyster card contactless payment system used in london's trains and buses. it's being part funded by the british government

to innovate gateless technologies, allowing passengers to simply walk into a station and onto a train. you can imagine, if you can get rid of the gate line in a place like victoria station, there's a massive potential for increasing throughput. so we ran quite an interesting project for them, which they are now installing at their laboratory in salford and the aim is to move it on to the underground so that the system will recognise people and you get rid of the gates and it will allow people to go through without any impediments. now, this is a is a prototype but we have been told that the system will recognise even a pair of glasses. so, let's see if it knows who i am now. look at that, you can see my name come up right there. it could make your life so easy. just walk around, the face is the key to doing everything you want to do in the modern world. and just to double—check, i've tried to fool it with this guy.

oh, look at that. it recognises me but this is very clearly an impostor. this face clearly isn't going to get me anywhere. dan simmons, being shredded. sorry, dan. so, that's it for another week. of course we'll be back with more next week from vegas including scott's hacker‘s guide to def con. until next week, then. hello.

the area of low pressure that brought wednesday's rain is still close enough during thursday to produce showers across the uk, making it quite windy too. it is gradually edging its way north—eastwards. not quickly enough for many of us before it gets to scandinavia and our weather improves. plenty of showers from the word go across many parts of the uk. the north and west in particular. some of these will be heavy. the risk of a rumble of thunder and perhaps some hail too. a look at the picture. eight o'clock in the morning, showers scattered in south—west england. much of central and eastern england will be dry at this stage. some sunny spells around. but you will notice through england and wales it is a windy day, unseasonably for the time of year. gusty winds at that.

plenty of showers in northern england and northern ireland, beginning to pull away actually. showers in scotland initially to the west. longer spells of rain in the northern isles. here we have easterly winds. brisk south—westerly gusts of wind in england and wales will be noticeable during the day. some sunny spells. showers fading in the afternoon, especially in england and wales. they linger on through the afternoon in scotland. slow—moving with lighter winds here. thundery downpours especially in eastern scotland into the afternoon. temperatures, high teens, low 20s. the first day of the women's british open golf at kingsbarn, not far from st andrews on thursday. we have the threat of some heavy showers moving through. some will fade thursday night into friday. could well see some spells of rain in ireland and scotland. edging southwards here for a time around the area of low pressure which hasn't quite yet got to scandinavia yet. the breeze is a notch down.

more in the way of sunshine. feeling pleasant between showers. and in fact, for the bulk of the uk, the showers away from scotland will be few and far between. those temperatures, well, into the low 20s in east anglia and south—east england. though most of us still pegged back into the high teens. the big picture going into the weekend, a ridge of high pressure trying to come in. we will still see showers on saturday, perhaps for a time in northern england, north wales, scotland, more numerous in those areas. temperatures in high teens, low 20s. after a chilly night on saturday, sunday delivers drier weather. though there is a weather system poised to come in from the west later in the day. welcome to bbc news, broadcasting to viewers in north america and around the globe. my name is mike embley. our top stories: fixing faulty genes
