the global cyber attack affecting almost 100 countries was ‘unprecedented' in scale. that's the assessment of europe's police agency europol. more than 2a hours after the hack the authorities say they are just now getting to grips with the problem. here in the uk for instance, the government says most hospitals are back running as normal after systems at the national health service were hit. daniel sandford has the latest. the cyber attack which wreaked such chaos in britain's health service was a global assault, affecting russia worst of all but also countries as far apart as the us, australia, and japan. this evening, the two british agencies tackling it said a complex international investigation would be needed to catch the culprits. we haven't identified the offenders at this moment in time, but we are deploying all covert and overt means available to us, and we have a number of lines of enquiry. it is important that we pursue those quickly so we can reassure the public we are taking this very seriously. at the heart of this global cyber attack was a software worm which spreads itself from computer to computer using code originally designed by us government spy agencies. it is called wannacrypt, and simply encrypts all the files on the infected computer and demands a ransom. by last night at least, 75,000 computers had been infected in at least 7a countries. at that point, a cyber security expert managed almost by chance to stop it spreading. but all the data on the affected computers is still unusable until a ransom is paid. any modern computer that had its software regularly updated was safe, but some nhs trusts use old operating systems that were particularly vulnerable — others may have simply failed to take a security update in march. today, the national cyber security centre had this simple advice. the first is to make sure your security software patches are up to date. the second is to employ proper good anti—virus software. and the third — and most important for ransomware protection — is to back up your data, because you cannot be held to ransom if you have a back—up. it has been a reminder of how vulnerable vital organisations are to attack by organised criminals seeking to raise money or by hostile states and terrorist groups trying to cause maximum disruption. the reality is there are thousands of vulnerabilities. for example, if we were to look at a company of 50,000 computers, we might find hundreds of thousands of open vulnerabilities on those machines. it is also reminder that computers are not a one—off investment. they need to be kept up—to—date. daniel sandford, bbc news. well, the attack has prompted finance ministers meeting at the g7 summit to call on banks around the world to test their systems and ensure they're safe. there's much more on our website, including advice on how to protect your own computer. go to bbc.com/news let's turn to some of the other stories making the news. north korea is

the winning song on twitter. for now, from me and the team, it's goodbye. take care. hello there. we could do with some rain for many of our gardens and we have got some of it. a weather front pushing its way west to east across the country. this is how we ended the day on saturday in angus. quite a bit of cloud around there. out of that cloud, we are seeing some outbreaks of rain but sunday should be a day of sunshine and a few scattered showers, too. here is the weather front that brought the rain to many of us overnight in the west, clearing to the east throughout the course of sunday morning. so a return to sunshine across many parts of the country. that rain will linger in the north—east of scotland. this is 9:00 in the morning, particularly for the northern isles, north—east of mainland scotland, too. some sunshine towards dumfries and galloway, towards northern ireland, too. a bright start to sunday here. a bit cloudier down the east coast of england, and you could catch a showerfirst thing, but actually much of northern england and wales look dry with some sunshine. you can just see a few showers starting to crop up across central parts of wales. almost anywhere could catch a shower later in the day but i think predominantly it is a dry picture through sunday morning. slightly cloudier skies for kent, up towards norfolk, with that lingering weather front. but the front clears fairly quickly towards the east and then across all of the country, it's just sunshine and a few scattered showers here and there. so you could catch a shower almost anywhere but they are few and far between, particularly along the south coast, it's largely sunny here. and temperatures 15—20 degrees, a pleasant day where you do dodge the showers. staying pretty wet up towards the northern isles. for some of sunday's featured premier league games, it looks largely dry but, again, there is a chance that one or two showers could sneak past at times. through the course of sunday evening, the showers ease away, so it's looking dry if you have a barbecue planned for sunday evening, for instance, and then overnight and into monday, the next batch of wet weather arrive from the west. it's goingh to be reasonably mild and frost—free, i think, wherever you are as we start the new working week. but for monday, this area of rain is with us for much of the day. heaviest towards the north and west where it will also be quite windy. the rain only quite light and patchy down towards the south—east where we really could do with some rainfall but the area of rain edging its way slowly northwards and eastwards through the day and we'll see temperatures still up there in the mid to high teens. so inbetween any spells of rain a reasonably pleasant sort of day. but low pressure stays in charge, bringing us the unsettled breezy and showery theme on monday and low pressure sticks around for much of the week ahead. into tuesday too we see this weather front bringing further outbreaks of rain at times. so tuesday into wednesday it is looking unsettled but the temperatures still remaining reasonably mild, up to around 21 degrees on tuesday. bye— bye. this is bbc world
