Against the islamic republic and sentenced to four years and three months in prison. Welcome to lake como. It's a beautiful part of italy, and the town of como itself was the home of the 18thcentury physicist alessandro volta, who is credited as being the inventor of. . . The battery. Correct! the clue was in the name. But i wonder if signore volta could ever have imagined his invention powering what alasdair keane has found on the same italian waters. There's a new race craft in town that's fast and designed to perfection. But this isn't racing on the road or in the air. Although actually they look more like scifi spacecraft than boats. This is the racebird it's been created for the allnew ei racing series that aims to prove the potential of electric power in the marine industry. We can use our sport platform in order to test and validate the solution, and then possibly change the way we will navigate in the future for billions of people. Hey, how are you doing? good. How are you? nice to meet you. You've just come off the boat. How was it out there on lake como? it was amazing. You know, our teams are working hard. We've been looking at data and we've been trying to do everything we can to be the fastest boat. We are the pioneers of a brandnew series. So, this is electric hydrofoil powerboat. There's nothing like it. This is the first invention of its type here that we're racing in e1 series. Will smith is here. He is who owns our team and we're looking to throw down, hopefully, some good times to get our first win. All right. Have fun. All right. Yeah, you did hear right. Will smith owns this team. And he isn't the only celebrity backer. Before the main event tomorrow, first some competition between the team owners. In the red, hollywood legend will smith. And in the orange and purple, tennis champion rafa nadal. Copy that. Ready to go. These boats can reach 50 knots. That's around 93km/h. So, how do they reach those speeds? the key bit here is getting up on the thin bits of the foil and staying above the water to have the speed. That's right, yeah? exactly. If you're on the edge of the foil and you're as high as possible, it's less drag in the water, so you're getting the more. . . The most kph. But, you know, there's some techniques that are coming into play as we learn these boats on what's fast. It's really tough to stay on the foil. You'll see us always doing as much as we can to stay on it, but it's not easy. We're very busy in the cockpit. We're doing a lot to make sure to keep the boat happy, but it always wants to stay unhappy, so it's a challenge, being a pilot in the racebird. With the boat back on dry land, there's a question i'm desperate to ask. Can we get in and have a look? of course, yeah. Brilliant. Thank you. It's tight. Yeah, it is very tight, yeah. Yeah, i think will smith had a bit of a hard time getting into that, actually. Can we fire it up? yeah, of course we can, yeah. We can't go to the full. . . Full load because we're in the garage. But basically, turn the master on. So, itjust takes a little while to boot up. You'll see the screen's just flashing on. When the pilots are out in the water, to get that important lift for the speed, they're actually having to press quite a lot of buttons and do quite a lot at the same time. Yeah, they are. Obviously, the most important one, which i haven't mentioned at the moment, is this one, which is the boost button. So, they'll add 20 seconds of boost and then they have to have a0 seconds of rest to cool the battery down. It's just drawing too much power. And while they lift. . . And that lifts them up onto the foils. While they're on the foils, we can then obviously play around with the lift, which is on the lefthand side of the wheel, and also on the lefthand side of the screen, and the trim on the righthand side. And we're just altering that by a few points, depending on wave conditions, or whether we're going into the corner. This sport is still in the very early stages. The nine teams have the same boat, but they're working out how to push the tech and try to get ahead of the competition. You try not to fly the boat out of the water because then there's no grip whatsoever. So, you actually need to have it in the water but as high up the water without the foils cavitating, without air being produced around the foils. You need to keep the flow attached to the foils, so that's the trick. And a lot of this is secrets? yeah, it's stuff that the teams are working on at the moment. We've all got different ideas about it. And, yeah, it's something that probably we're all doing exactly the same, but we're not going to tell each other that we're doing it. As the day's practice sessions come to an end, are westbrook racing feeling the extra pressure of their owner watching on? we're racers, we're used to this pressure, right? we thrive off of that. So, of course, there's always pressure, no matter what, whenever you get into anything to perform, and so i don't think it's adding any extra. But obviously we want to make him proud and we want to win just as bad as he does, and so we're doing everything we possibly can to make that happen. Doing everything means working late into the night to make sure the boats are in the best condition for tomorrow's races. And you can find out how the teams did when we return for race day later in the programme. Now, two years ago this week, mahsa amini was arrested in iran for not wearing her mandatory hijab correctly. She later died in police custody and her death prompted a wave of protests across the country, bringing the phrase woman, life, freedom to international prominence. The iranian government is now using digital surveillance to clamp down hard on dissent and bbc verify's reha kansara has been speaking to some of the iranians arrested for their social media activity. And just a warning, this report includes accounts of violence that you may find distressing. Chanting i was accused of propaganda against the islamic republic and sentenced to four years and three months in prison. Over the past few months, we've carefully gathered the testimonies of five people from iran who were arrested for their social media activity. The bbc and other independent media are not allowed to report freely from the country. They've taken great risks speaking with us, and for their safety, we've kept some details vague. Court documents shared with us show iranian authorities are using social media to build cases against people, charging them with propaganda against the state and for taking part in the women, life, freedom protests. Chanting and clapping. Shortly after the iranian revolution in 1979, women were legally required to cover their hair, but these protests, ignited by the death of mahsa amini in 2022, have unleashed a stream of civil disobedience on social media and on the streets. Police firing into crowds. . . Gunshots. . . Women cutting their hair and burning hijabs in rage. Zan, zendegi, azadi, meaning woman, life, freedom, became the rallying cry for women's rights in iran. Now the movement's being met with an even harsher clampdown on dissent using state surveillance. I had joined a protest and i got into an argument with a group of islamic republic forces blocking the road. One officer started shooting at my body with a _ paintball gun. He shot me in the eye. With a smirk on his face. I lost my eye. I had gone blind. I posted about those who were killed and injured like me, and through our instagram pages, we became the voices of those who had experienced what we had. L in my court sessions, they had printed outl all my instagram stories. There was a heavy case against me. Based on my social media. Kosar was sentenced to over four years in prison and was banned from using social media and smartphones. Her charges included propaganda against the islamic republic. She says she had no choice but to leave the country. Chanting. The commander of iran's riot police has denied his forces intentionally shot protesters in the face. And like kosar, four of the bbc sources received suspended prison sentences and remain in iran. So, how is the state spying on its citizens? in the past, it's relied on more traditional methods, like reporting your neighbours to the authorities. But with the advent of the internet, it's become much more pervasive. Within the first few months, we saw upwards of 20,000 protesters arrested. And of course, the majority of these protesters belong to gen z. And of course, we know gen z are extremely online. Their digital footprints are very wide. And so relying on the content on their social media, their private messages, either when they're incarcerated through detaining their devices or through tracking, you know, the activities of protesters before they're detained, we saw a lot of this kind of surveillance and monitoring. The islamic republic has also advanced technologically to tighten its grip on society. They've built their own version of the internet, incentivising it by making it cheaper to use than the world wide web. But iranians are cautious because accessing it means handing over your data to the government. The government has also reportedly used phishing techniques to hack devices and access people's data. They've blocked western social media platforms, like instagram, whatsapp and telegram, because they cannot control them. But iranians are using vpns to disguise their location and access these platforms. Experts say iran is learning from surveillance states like china and intensifying its methods to catch women who refuse to wear the hijab. They can geolocate your. . . . . Where is your mobile phone. They can see what mobile phone is connected to what kind of ip addresses, and then they figure it out, what's the identity of the people who are using that particular mobile phone? they can track you. They have developed some mobile phone applications and other tools for the police or those volunteers who are already vetted by the government. Un experts have told the bbc noone should be jailed for a peaceful post online. We contacted the iranian government and put forward to them the allegations made, but they did not respond. And though mass demonstrations have come to a halt, people are protesting in more subtle ways. And this movement that's led by women and driven by a right to life and freedom shows no signs of stopping. I feel a lot of sorrow about it, but i now really cherish this eye injury. It's living proof of a crime against humanity for me. Time for a look at this week *s tech news.

One of the world's busiest tourist spots times square, here in new york city. It's an unlikely location for a highly secure facility that monitors foreign governments' attempts to destabilise democracy. But that's precisely what's going on in an office building that way. Away from the crowds and traffic, we've gained exclusive access to mtac the microsoft threat analysis centre. The work that's carried out here is extremely sensitive. We're the very first people that have been permitted to film inside. Take a look now at an actor. Founded by former employees of the russian ministry of defence. Individuals from this organisation serve on a special presidential committee in the kremlin, advising putin on russia's war in ukraine. Analysts here advise governments like the uk and us, as well as private companies, about a variety of digital threats. We're known as mtac. Its job is to detect and assess and disrupt any sort of influence threats, we would say, cyberenabled influence threats to democracies worldwide. Specialist teams here focus on different potential perpetrators of digital threats. They call the people behind these disruptions threat actors. We have a russia analysis team, an iran team and a china team to try and detect everything from propaganda to disinformation. For russia, it's always a constant. They see political warfare as part and parcel of their foreign policy objectives worldwide. So, we've seen them continue their campaigns with disinformation outlets we've tracked. The us department ofjustice recently announced it had seized 32 websites tied to a kremlinaligned online influence campaign. Dubbed doppelganger, it uses aigenerated content, targeting us elections, the war in ukraine, as well as spreading prorussian narratives. The fbi had this to say about doppelganger. By seizing these websites, the fbi is making clear to the world what they are russian attempts to interfere in our elections and influence our society. Doppelganger is best known for cloning the websites of well known international media. It makes fake versions of fox news, the washington post, which look very much like. The original but are reworked entirely with _ prorussian propaganda. So, you've got some examples up on your screen here. This one here this is an article which says it's from fox news but is in fact an article which is from this group called doppelganger. This was in fact. Made in moscow. Iran has just entered the fold in recent months. Four years ago, in 2020, we saw them come in very late, using both cyber attacks and influence operations to try and cause chaos. This is one of the newer sites the iranians have stood up as part of a set of inauthentic news sites. Fake social media accounts retweet and support them. They're focused on stories that are antisaudi, antiisraeli, antiamerican and those are often telltale signs that something is potentially iranianrun. Then china, in previous cycles, we saw almost nothing from china. But in this case, we do see them establishing social media accounts and websites, which they use to provoke some sort of conversations with american voters. And this is the first cycle where we've had all three that we can definitely point to. And the dramatic nature of the us election has created complications for those attempting to interfere with the process. The biggest impact of the switch of
