Is growing suspicion that north korea was behind last weeks global cyber attack. A number of people have been looking at some of the code. This was shared by a google researcher, clearly i cant explain it, but he is telling us it is a sample of the code used by the hackers in the attack. Lots of people who know more about these things than me spotted similarities toa things than me spotted similarities to a previous cyber attack, namely the attack on Sony Pictures. It came just ahead of the release of the film the interview, based around the assassination of kim jong un, a comedy. That attack was carried out why the Lazarus Group, a criminal organisation with no links to north korea. So we climb and gives an assessment. The manhunt is on to try and find the who was responsible. One of the clues is analysing the code that has been found in this ra nsomwa re. Code that has been found in this ransomware. It seems to be similar to an earlier form of malware that was used by the Lazarus Group a few yea rs was used by the Lazarus Group a few years ago. You may not have heard of them, but they are best known, their notoriety if you like is that they we re notoriety if you like is that they were supposed to be behind the Sony Pictures hack, which was massive in 2014. They have links to north korea. North korea of course has denied all of this. There are other clues that might suggest other things. Another expert is saying the way that the Ransomware Demand was written, the one that was written in chinese felt like the miz in terms of the tone of the language. Perhaps it was somebody either in china or from china. There are all sorts of theories bouncing about. Another thing that everybody wants to do is follow the money. All of this money has gone into these three Bitcoin Wallets a nd has gone into these three Bitcoin Wallets and it has not been touched. The eyes of the world on these wallets. Who is going to take that money out . The way that bitcoin is set up, there is no easy way to know who has access to those wallets. Set up, there is no easy way to know who has access to those walletsm isa who has access to those walletsm is a much more anomalous forms and saying, i want a ransom, is a much more anomalous forms and saying, iwant a ransom, here is a much more anomalous forms and saying, i want a ransom, here are my bank account the towels anonymous form. This hasnt worked out quite right. Normally a Ransomware Gang would have a different bitcoin account, is one that, kind of like a bank account for each demand. The idea is that everybody puts in their few hundred dollars, £200, they empty the account, it disappears and the money is gone. This hasnt happened in this case. What is fascinating for those who are searching for this people, what does this mean . Is this gang not one of the professionals . Have they not done this befores has it got out of hands it looks like it is possible there were meant to be more wallets but they were not set up in time. Does that make it easier or harder to find them . If they are not very professional, might they split up ain . Professional, might they split up again . But nobody knows who they are. They are totally out there in the wild. While this manhunt is going on, lots of Different Countries and corporations are working out how to improve their defences. Right, the big lesson that has come out of all of this is that you ignore Security Patches that rob burrow. All of the it people are having a field day and saying, we have been warning the three years ignored Security Patches at your peril. Everybody is learning to be more prepared. This is not sophisticated malware, it took advantage of an exploit that had been made public, that is how these things work. The fact that it is on such an impressive than to scale has been a huge wake up call for the world. An unprecedented scale. Lets begin outside source sport by talking about the two countries vying to hold the 2024 summer olympics. We have los angeles versus paris. Pariss bid hasjust received a major boost. The new president , emmanuel macron, said he supports the bid and he will travel to the ioc headquarters in switzerland in july when these two cities will make their final cases. The july when these two cities will make theirfinal cases. The bbc sport editor dan roan has been looking at this story. Here is his latest report. He isjust three this story. Here is his latest report. He is just three days this story. Here is his latest report. He isjust three days into thejob, but report. He isjust three days into the job, but frances report. He isjust three days into thejob, but frances new report. He isjust three days into the job, but frances new president has wasted little time in backing pariss bid to host the 2024 olympic games. Welcoming members of the International Olympic committee to be italys a palace on the final day of their inspection committee. Paris has committed to spending billions of the event, the city mayor told me why. It will transform paris, with the village and after the games, a village for the athletes will be housing for people, and we need housing for people, and we need housing for people in the north of paris. So we are very, very committed. Sports Showpiece Event a lwa ys committed. Sports Showpiece Event always divides magical moments. But the sight of rio 2016s abandoned olympic park has once again raised questions over legacy and the vast cost of playing host means the games have an image problem. Cost of playing host means the games have an image problemlj cost of playing host means the games have an image problem. I will be right here in the city of angels, watching the olympics. Despite all of this, los angeles also wants to host the games. Its bid is privately financed, with the venues already built. Mike harris, it has received Wawrinka Rays from the ioc. Like paris. Things that you point to a Budget Issues and engaging youth, those things literally go away. Budget issues and engaging youth, those things literally go awaym becomes the liverpool as part of our bid. There are challenges facing the olympic movement, we can combo waters for seven years, that is exactly what they need. Calm the waters. The ioc has become accustomed to being courted by heads of state. But this Evaluation Commission will only decide between two rival cities after a host of others pulled out of the race due to a lack of public or political support. It could force the ioc into one charted territory. Whichever city losers look set to be offered the 2020 eight games as a consolation prize, as the ioc considers an unprecedented two games deal in september to avoid the risk of having no bidders. It is something that we all have to look at and have to figure out why that, you know, how events are not maybe as attractive as they were 20 or 30 yea rs as attractive as they were 20 or 30 years ago. We should always be challenging ourselves as to how we can make these events is more appropriate for local communities. We do need to communicate some of those values, and im not sure that, you know, im not sure any of us have really done that. This two horse race seems too close to call. Paris and alejandro is that the olympics before and insist their focus is solely on the 2024 games and la. But at a critical time for the future of the event, the ioc knows that the race is on to provide a solution. Last night on sport we we re a solution. Last night on sport we were talking about how Roger Federer will not be given to the french open. To that list you can add borre sharapova. She has not been offered the wild card. There was a lot of interest in this because it was the first major she could have competed in since her debut band. The organisers were never giving her too much hope. Doping ban. The head of the French Tennis Federation put it this way, this is not a rock opera, meaning that sharapova would not be getting any favours because she is a big name. So it has proved. Lets bring in mick mccormac. What is the process that goes into deciding whether Maria Sharapova gets a wild card or not . There is a long, long meeting between all of the tennis officials. But ultimately what they had to decide he was, was herform what they had to decide he was, was her form warranted to get her in here, or were they going to bypass the fact that she had come back from a doping test . It was a principled decision that the Tennis Federation took in france, because they said that while the fans were disappointed and character of might be disappointed, he had to take a strong, principled decision against doping in sport sharapova might be disappointed. She was ranked outside the top 200 after the 15 month ban. The long and short of it is that she didnt have the form and it would have given the wrong message for the French Tennis Federation to allow her to walk in there without having done the legwork. That is the long and short of it, really. What about wimbledon . Interestingly, the last hour or so just from now, sharapova has withdrawn from the italian open in the second round of her game against baroni. She was up in the third set but she has retired. She had her left thigh heavily strapped. Really interesting to follow that, we will be across it. If she hasnt made the semifinals in rome she would have qualified automatically for the main draw of wimbledon. So now it is up to her to qualified through the tournament in south london. She has made it harderfor tournament in south london. She has made it harder for herself. Interesting to note as well but maybe wimbledon would have watched what the French Tennis Federation would have done with their decision. Because they too can still offer her a wild card away from all of this qualifying, but the president might have just been set in paris. Their re entry in, thank you, nick. Next on outside source we have two bits of incredible footage very intriguing. This is from the wind surf slalom world tour. This event is taking place injapan at a place called suki harmer beach. This particular discipline involves these quys particular discipline involves these guys going very, very fast around a series of set for yous. It is not dissimilar to races you would have seen. You imagined they would be invited back. A french man won the mens rea is. The next leg is in spain. That itself is impressive. Stick a windsurf on some snow, also in japan, this is what you get. Ive never seen anything like this before today. This guy is from the us, he isa today. This guy is from the us, he is a professional windsurfer who also snowboards. He has put two and two together. This is now crush here injapan, the mind really boggles as you watch this. This is a mountain injapan. Hitting the speed is going down the mountain, just incredible. Very impressive, isnt it . I have a new report from david shukman, the bbcs science editor. He has been injordan because the king ofjordan has just he has been injordan because the king Ofjordan Hasjust opened a new science laboratory, and it is an impressive collaboration, certainly by The Middle East standards. In a rare show of unity we have jordanian, iranian, israeli and palestinian scientists all working together on this one project which isa together on this one project which is a Particle Accelerator which can then act as a powerful microscope. Ill let david explained. Im injordan at a new Research Centre called sesame and around me is a machine called a synchrotron that acts as an incredibly powerful microscope. There are some 60 of these around the world, and they are used to study everything from pharmaceuticals to plants to ancient remains. This is the first to be built here in The Middle East. Whats the big deal, you might think. Well, listen to some of the countries involved in this project. Theresjordan, of course, egypt, turkey, cyprus, iran and, amazingly, israel as well. One of the people who has been steering this project to fruition is the british physicist Chris Llewellyn smith. How amazed are you, given the sort of countries involved, given how hostile they can be to each other, that here you are today, the thing is starting to work . The scientists involved in Sesame Overlook the politics. They Work Together as scientists, producing a facility they want to use. If its a time of particular tension in the region, of course, they can feel a bit uncomfortable but nothing serious has happened. Did you ever wake up in the morning, hear the news of some new conflict in The Middle East, a new source of tension and think, surely, the various partners will have to walk away now . Not really, because i understood, meeting them, that they want this to happen, at least at the level of the scientists. The real problem has been finding the money. The countries in this region have Science Budgets that you can hardly see with a microscope, most of them. There have been many times in the history of this project where a rational person would have said, lets give up, but it seemed important to keep going and here we are today. Were launching the project, albeit with minimal supporting infrastructure, but its going to work, its producing science. Its a very great moment. Do you have to pinch yourselves, now and again, that actually, you pulled it off . I suppose so, but that would sound a little bit arrogant. Congratulations. Chris Llewellyn Smith there, thanks very much indeed. So the real test comes now when teams of iranian, israeli, palestinian, turkish scientists, all come here to use the facility and its meant to run for many years. Well, that the story to inspire us. Inafew well, that the story to inspire us. In a few minutes we will turn to a story that has made many hearts heavy, a celebrated mexican journalist was shot dead in the street yesterday. He had been reporting on drug cartels. We will have a report on that from mexico city. Greater Manchester Police say the death of the moors murderer, ian brady, wont stop them looking for the remains of keith bennett, who was the only one of his five child victims never found. Brady, and his partner myra hindley , abducted the 12 year old in 1964, and refused to say where he was buried. Judith moritz reports. His name will always be notorious, his face the image of evil, his crimes amongst the worst of the 20th century ian brady, the moors murderer. He took children and tortured them, and brought their bodies high up to the hills above manchester. On the desolate moors, the police spent years searching for their remains. Bradys accomplice was his girlfriend, myra hindley, she died 15 years ago. Bradys death closes a chapter of criminal history. Five children died at their hands. The youngest, lesley ann downey, was just ten years old. Her family are still grieving. At their trial, the pair were met with publicjeers. Sentenced to life, brady was at first taken to prison. But in 1985, he was transferred to ashworth, a high security hospital. From there, he wrote letters. In one, he claimed to feel remorse, but he never showed any sympathy to the family of 12 year old keith bennett, whose remains were never located. It consumed the life of his mother, winniejohnson, who spoke to me before she died. I want it coming to an end, and i want keith found. Ive asked him before. When i found out that id got cancer, and i said, i want to know where keith is before anything happens to me. Winnie often went to the moors, and never gave up hope that her son would be found. The police say that virtually every week someone gets in Touch Purporting to be able to lead them to keith, but theyre not actively searching the moors at the moment. They say though that theyll never close the case, and ian bradys death doesnt change that. Yesterday, knowing his death was imminent, brady called his solicitor to see him. They spent two hours together. I dont think there was anything he really knew or had any information that would assist in the location of Keith Bennetts body. Did brady say anything which would give the families of the victims any comfort . No. Today, a coroner said that bradys ashes must not be scattered across these moors. Bad enough that hes taken his saddleworth secret to the grave controlling and cruel to the last. Judith moritz, bbc news. Im ros atkins an outside source, live in the bbc newsroom. Our lead story is that donald trump has been defending his decision to share intelligence with the Russian Foreign minister. His National Security adviser says that no sources were compromised. Next on outside source, i want to turn to a very important story in nigeria. The issue of kidnapping. The country is suffering its worst economic crisis in decades, and that is having a Knock On Effect in this particular type of crime. In lagos alone, more than 50 kidnappings were reported last year, but analysts think the true figure was far higher because kidnappings go unreported as families pay ransom is rather than involving the police. The bbc has spoken to for people who have been kidnapped recently. These are their stories. There was a bullet, shooting, shooting. They killed one of my security guys. They even shot one of my wives they took us to a creek, we were beaten with machetes. We thought it was the end. It was like a forest. There was water, mosquitoes were our friends there. And the snakes. Next on outside source, i want to talk about javier valdez. He was next on outside source, i want to talk aboutjavier valdez. He was an Award Winning journalist who was
