so it's a cool start to monday. some early morning sunshine will quickly be spoilt by quite a lot of cloud developing into the afternoon, and a few sharp showers as well could break out across south wales and southwest england. temperatures subdued, really, for early august — the maximum of 20 degrees, but perhaps feeling even cooler on those exposed northeast coasts. dry, settled and a little more sunshine around on tuesday, but still not particularly warm. hello, this is bbc news with martine croxall. the headlines: more gold for team gb in tokyo. magnificent max whitlock retains his olympic pommel horse title. i can't even describe the feeling. i feel completely overwhelmed and it feels very, very surreal. and charlotte worthington claims another gold medal for britain in a dramatic bmx

park freestyle final. and more olympic drama at tokyo airport as a belarusian athlete claims officials from her country tried to forcibly repatriate her. the uk has accused iran of being behind an attack on an oil tanker off the coast of oman in which a british national was killed. young people in england will be offered incentives to have their first covid jab, like discounts for takeaway food and taxi journeys. now on bbc news, it's time for click.

it is the land of fire and ice. where the earth is literally splitting apart. this is iceland, home to so much amazing scenery, created by the superheated rock that lurks just below the surface. as recently as march this year, a new volcano�*s been erupting and attracting tourists and scientists alike to watch and learn as it rewrites the geography once again. and, later in the programme, we will be there to see how — as long as you're careful — volcanoes and drones can mix. now, iceland is putting all of this heat to good use. it drives the geothermal power stations which provide clean,

cheap electricity, and that means that now, nearly half of all of the cars here are electric. the country is second only to norway in its adoption. but while things are moving at a pretty fast pace here in iceland, the uk is still trying to increase the number of publicly available charging points to help with the switch to electric there, and that means that home charging points are a must—have for early adopters. but here's a question i bet you've never asked yourself — how secure is your charger? weird question, i know, but dan simmons has been investigating how your charging point could be turned against you. ready to plug in. well, the porsche does get thirsty and as many electric car owners will testify, having a charger at home is almost a necessity to make sure you can go places tomorrow. beep.

but all is not as it seems. because this smart charger has mysteriously switched off. beep. next day, our man is often an important meeting, no doubt, and to show off his flashy new motor. —— off to an important meeting. but he's going nowhere because his tican can't — its battery is still flat. his car's ok — it's the wallbox charger that's been hacked and turned off. and it gets worse. because hackers can access the firmware of this second charger, the project ev, they can disable this permanently. both chargers have been approved for sale in the uk by the government's department of transport. so, how can this happen? well, thankfully, the good guys have found the problems first. the number of so—called �*white hat�* hackers is growing fast —

these are the people who test systems and products to find flaws before anyone else does. vangelis is the hacker who found the security failures. so, on wallbox, you could take full control of the charger. it could gain full access and remove the usual owner's access on the charger. it could stop them from charging their own vehicles and provide free charging to an attacker vehicle. and for the project ev, it's way worse because you can sideload finware, you can make it — you can brick it, you can make it to be part a modnet and you could also make attack other servers. make it attack other servers. the problem in both cases is the lack of proper authentication between the mobile app on our smartphones often used to control these chargers

and the computer servers that relay instructions to the boxes�*. do you think it's an easy hike to do? could anyone do it? —— easy hack. yes. well, the word "anyone" is quite broad, but anyone who understands apis could easily do it, yes. ken munro heads up pen test partners. after a quick charge—up, we went back to his place where he showed me something else particularly worrying. if you've got one of these chargers at home, then you might be surprised to find this inside. ken and his team found a 2015 raspberry pi — more of an educational piece of hardware rather than something that you may want to rely on to store your details securely. get hold of one of these and because this is connected to your home by wi—fi, well then, you can get straight onto the home network. could let you do

all sorts of things. shall we change the channel? click theme plays. mum? spencer: hey, welcome to click. it's more educational! if you've got the project ev charger, you can do it without even having access to the box. you can do it remotely. so, once you're onto someone's home network, if you haven't changed that router admin password, you can send all the traffic to the hacker. that means they can do things like set up sites that look like the real deal but steal your passwords and then your real bank account, for example, has been compromised. so, there's all sorts of things you can do. anything you log into, you can potentially intercept that traffic or grab it and then reuse it, so everything you do online is potentially exposed. and with many of us now working from home, confidential commercial information might

also incentivise an attacker. if you're a small business and you've got one of these charges and it's connected to your business network, you've potentially created a backdoor onto your network, access to potentially all of your data, and that's going to put you in a whole lot of pain. and new sharing schemes promise to make security even more important as owners of charges are encouraged to let other ev users pull onto their driveways and charge up. thousands of these two chargers have been sold in the uk, so both pen test partners and click contacted the firms to first give them the chance to fix the problems. we got two different responses. project ev imports chargers from a company based in china called atess. it told us:

wallbox, based in spain, didn't reply to us, but they did tell ken's team that they had fixed the online problems. time to see if the units are safe. retesting took place this week and suggests most of the problems in both chargers have been fixed, but ken says owners still need to take action. check for updates, solve the problem. the wallbox charger uses hardware that isn't secure enough. there's really nothing you can do to make it completely secure. so, unless wallbox have found a way of fixing that, which would be beyond me, i'd suggest perhaps supergluing the box cover in so hackers can't take the top off. and what of the approval they had to be sold in the uk by the department of transport and the government grants

handed out to help sell them? the department did not comment on the security issues we raised, but said: it's worth noting that all smart home chargers will still be usable if you just want to plug your car in. but when it comes to security when using them with a phone app or home wi—fi, it seems some are smarter than others. my name is christopher hamilton, i am an associate professor my name is christopher hamilton, i'm an associate professor at the university of arizona and a planetary volcanologist. we're here in geldingadalir, which is a new volcanic eruption that has occurred in southern iceland in reykjanes. iceland provides an ideal

testbed for being able to test different kinds of drones for mars because the wonderful characteristics of the environment are actually very similar to what we would expect on mars. so, this has been a really exciting year for mars exploration. the drone ingenuity has demonstrated flight on mars for the very first time, being able to operate in a very thin atmosphere, about i% of what the earth's atmosphere is. is it still giving you that warning? no. the other drone we are using has a larger payload, has a number of different cameras and zoom functions, really beautiful, but also a lidar instrument. so, lidar uses light to be able to range the distance between the sensor that is emitting a set of photons and a surface. it's a world first to be able to use a drone—based lidar to image the lava flow and develop a time series topography which we can use to inform the thickness of lava, the volume, and ultimately, the amount of lava that's coming out of a volcano at a particular time.

today, we're mainly trying a thermal infrared camera which measures the temperature of the lava, which is a first for us to be able to do from the air with this system. even though we don't see it with our eyes we can actually map out regions that are hot and potentially having lava flowing underneath the crust. we are also testing a series of things like grippers, basically a claw that can be used to pick up loose examples, but also drills that can actually core a sample using the drill and bring it back to a lander or even a roverfor further analysis. the different drones, the different instruments, the different mission concepts we're putting together will enable new exploration of the red planet and to see parts of the planet we have never seen before, and i hope we'll have an opportunity, perhaps in the coming decade, to send a drone dedicated to exploring mars�* volcanoes and for the first time see if potentially they're harbouring evidence of life. past or present. are we alone in the universe, but also where did we begin, and potentially, what is the world like in the future that we will come to inhabit as well?

that was christopher hamilton. how spectacular was that? and that's it for the shortcut of this week's click. the full—length version is waiting for you right now on iplayer and we are waiting for you on social media — on youtube, facebook, instagram and twitter at @bbcclick. thanks for watching and we'll see you soon. hello, i'm marc edwards. welcome to

old become just the sixth briton to win at least six olympic medals. john watson was at the ariake gymnastics centre to witness whitlock�*s wonderful world class win. max whitlock defending his title he won in 2016. it was a nerd nerveless display. which be toppled. he has been the man to beat. he's had i had targets on his back but he couldn't be overhauled. he was naturally delighted to have won a third olympic gold. i delighted to have won a third olympic gold-— delighted to have won a third olm-uicold. �* ,. , olympic gold. i can't even describe the feeling- — olympic gold. i can't even describe the feeling- i _ olympic gold. i can't even describe the feeling. i feel— olympic gold. i can't even describe the feeling. i feel completely - the feeling. i feel completely overwhelmed and it feels very, very surreal. it was an incredible, washing the sports. the gold medals have been flowing in and ijust want

to do the same thing and come out here and get
