hello. this is bbc news. the headlines... president trump has criticised china on twitter, saying it's doing nothing to halt north korea's weapons programme after pyongyang test—fired its second intercontinental ballistic missile in a month. the australian prime minister says counter—terror police have foiled an attempt to blow—up a plane. four people have been arrested in raids across sydney. the threat of terrorism is very real. the disruption operation, the effo rts real. the disruption operation, the efforts overnight, have been very effective, but there is more work to do. the international trade secretary liam fox has said the government would not be keeping faith with the eu referendum result if it allowed the free movement of people to continue after brexit. but the chancellor philip hammond has previously said it will be some time before full migration controls can be introduced. a record number of criminals have had their sentences increased after victims and members of the public asked

for them to be reviewed. 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! superfast knot tying. wide open spaces.

limos. the strip. and, this week, the largest hack—fest 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 defcon 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 hack 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? our skype&type 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. as you can see, 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 is notjust our victim, he's also a security researcher who is 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 took a bit of setup 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 ra nsomwa re, in part because it's 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'm wrong. so, here is one which is very popular. this one. if i type it into google... then we can just download it straightaway. this is the code. this is free. that's it, you don't have to go on to the dark net 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. and sure enough, the programme turns all of our sample documents into illegible garbage, which can now only be retrieved if the creators — in this case us — provide the unlock code. ok, 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, right! next we hop onto a site that will connect me with people who will set up and run ransomware for me. so, this guy here will charge you $125. these guys, they'll give you lots of customer support. they also offer you some advice on how to deliver it to people. it's a full on service, this? yeah, yeah, and via your phone you can talk to this guy over telegram or instant messenger chat. and if you're too lazy to send this to people, to get them infected there is 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?! oh, my goodness! surely you can engage this person in chat and go and get them, 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. doesn't it you? i'm going to unplug the internet! i'm leaving. 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 that 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 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 ina 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 that is freely available to the general user. so if you are 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 particularly 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 cybercriminal? what 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, 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 three. 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, aged 16—20, 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 cybercrime himself. i was 17 years old. i was getting drawn into making my own malicious code, making my own exploits, 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 counterterrorism 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. several large companies are here to talk future job opportunities. the uk hasn't got enough people to protect itself. businesses, the nation, individual accounts, we all need protecting, and that's why we exist. we need to find these people. they're there. we know they're there, we need to find them. these offenders know this is a second chance, one they didn't realise they were so well qualified for. i was more interested in the dark side, back when i was young. i wasn't really looking at the good side. the dark side was mainlyjust 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. 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, an attacker has come to the front of the atm, they've drilled a hole in the front. what we can do now, you can see we can access this usb cable. right, so, inside here 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 they are not particularly secure, so you could put malware on a system that could collect data from cards as well. that would be information that is 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, "ncr provides its customers with comprehensive recommendations and security defences to address these challenges and help them to assess and improve their security infrastructure." 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 microchipping 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 try 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 or 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 password 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, 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 3d 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 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 3d 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 me 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. well, it has been the classic mixed bag today. the weather can't make up its mind. sunshine and downpours and thatis its mind. sunshine and downpours and that is likely to continue for the next 2a hours at least. there are some fine weather around as well. a picture here earlier on from norfolk. the further east and south

you are, the better the weather will be today. the satellite image coming in and see patterns in cloud formations. these are clusters of showers racing across the country. the closer you are too low pressure in the north and west, the more frequent and the more heavy the showers will be. some of them, real downpours, with thunder and lightning, hail as well. we have already had some areas affected by downpours, not just by already had some areas affected by downpours, notjust by the showers but the rain from us might as well. the isle of wight, around surrey and essex, this is a snapshot, around 6pm, it may stay dry all through the day. looking out to sea, the weather is looking beautiful, with clear blue skies. showers in many areas will continue past sunset. lots of clear spells developing across southern and central areas. in the north, where the clear spells occur, temperatures in rural spots could be as low as 5 degrees. these are the city temperatures, that we often show you. monday, low pressure is

still with us. that means the overall weather pattern is not going to change, the closer you are to the centre of the low—pressure, the more frequent and heavy the showers will be. scotland and the north of england getting a good dose of showers, the south is drier and brighter, in london and norwich. tuesday, we still have showers. a continuation of the same thing. showers across northern and western areas. a dry and brighter day in the far south—east of the country. on wednesday we have low—pressure approaching. that is a more substantial area of thick cloud and outbreaks of rain. notjust the hit and miss showers. that is going to reach the south west, wales and eventually northern ireland during the afternoon. through the afternoon, we think the rain will be reaching northern areas. this is early in the day. we could see brightness and dry areas in the east. this pattern is going to continue into the end of the week, with the jet stream racing in our

direction. this is bbc news. the headlines at apm: president trump has criticised china on twitter, saying it's doing nothing to halt north korea's weapons programme after pyongyang test—fired its second intercontinental ballistic missile in a month. security has been tightened at airports across australia after the authorities said they'd disrupted a plot to blow up a plane. four people have been arrested following raids across sydney. the threat of terrorism is very real and the disruption operation, the efforts overnight have been very effective but there is more work to do. the international trade secretary liam fox has said the government would not be keeping faith with the eu referendum result if it allowed the free movement of people to continue after brexit. a record number of criminals have had their sentences increased after victims and members of the public asked for them to be reviewed.
