of thousands of russians are called up to fight in ukraine. some men of military age are fleeing the country to avoid conscription. others have taken to the streets in rare demonstrations of resistance to the war. you're up to date on dw news. i'll be back at the top of the hour with more headlines for you in the meantime. don't forget, you can get lots more news and information on our website. just go to d, w dot com. stay tuned for our tech show shift to which asked how safe the internet is against cyber attacks. a marion evans team from me and the entire news team thanks for watching. with every journey is full of surprises. we've gone all out to give you some tips with all who read reason. i'm in your northernmost count,

the police ah 3 times long. but still very much alive. d w, travel, you'll go to this essential thought in germany a recognizes where exactly. it was fun. i learned a lot, our culture history, all their d. w. travel extremely worth a visit. ah, how, what cuts traffic at a standstill? no more water and hospitals in a state of emergency. if the internet collapses, the world could be plunged into chaos as almost everything is connected these days . how likely are internet blackouts to day on ship? mm. i

imagine this, the internet collapses worldwide. it could be the result of an accident or a cyber attack. what would this mean for all of us? the consequences would definitely be graver than not being able to check social media for half an hour, government's bangs and supermarkets, nearly every thing is dependent on the internet. it has revolutionized our lives. today, around 5000000000 people across the globe have access to the world wide web. the internet permeates all areas of life. it's getting bigger, faster, and more all encompassing. this creates dependencies and risks in her book error for all 4 spanish science journalists, esther pony. onqua deals with the sperry topic. everything is connected to the internet and that means shots that means hospitals that mean every sort of public

administration and government and services. every company, media, of course media companies, everything is connected. so the longer it last they the great, there are the more serious air, the impact will be and, and we're not prepared for them. the world wide web was developed in the late 19 eighties, primarily to enable communication between universities. back then online shopping and video streaming were still things of a distant future. but the internet quickly spread to other areas of life. it was now created for support in all of the companies and processes, all of the corners are happening in all of the and critical infrastructures and government services. everything is going on and it was now created for that is the internet in danger. for ester pontiac, glock, it's just

a matter of time before the world wide web collapses. wherever we are very many examples, it hasn't happened affect global scale, but it has happen at the massive scale. so it will happen at the global scale to morrow in 5 years, in 10 years, or never. are we really at risk of a global internet blackout? well, let's take a closer look at this. it's true, the internet was not developed for his current use. still it's infrastructure is pretty robust. sandita abdur, jody research is internet resilience at the university of california, an oven, in her opinion, a global blackout, whether you do technical issues or cyber attacks is not that likely. and perhaps surprisingly, she says that's because of the old structure of the internet. a lot of the origin

of the sign was really good. that's why you, you still have nearly the same architecture today. after 30 years, since they're interacting, pasco is laid down in a late eighty's early ninety's. you've never had a global outpatient. we've had certain services going out certain parts of the network oh feed, but not a really global it. one advantage of the architecture, the internet isn't actually one giant network. the internet has a decentralized digital infrastructure. it's composed of multiple smaller networks . so called autonomous systems, which each control a small part of the internet and are connected through nodal points. if one or even more of these autonomy systems breaks down, the internet still remains stable. due to its distribution and decent life nature, internet infrastructure figured i see him on the broad acosta constant. the back end of the internet have oh, can, can wish to

a little bit bots and utilize the existing structure on the a. and i think that investors are doing gates a gazes of lots k fia protocols, regulate data exchange, but they are vulnerable, like the domain name system or dns, which works like a telephone book for the internet. it connects domain names like google, dot com with the corresponding servers ip address to ensure that user requests are forwarded to the correct server. the border gateway protocol, or b, g p, can also be vulnerable. as the internet's navigation system. it regulates data traffic and ensures that data packets take the best route through the web. b, d, b is the protocol that gives us a router or the internet. it's possible for malicious. does to advertise a rope on, on the a, b, b, a network. oh, which directs you to

a false rock the possible consequences. users might not be able to reach certain websites or get directed to fake sites where hackers can access their data. since protocols are also di, centrally organized, it's unlikely that a b g p attack would lead to the internet breaking down entirely. by the way, facebook had a huge pgp problem in october 2021. for 6 hours. the company's services were down. the reason behind this request went ot routed to the correct servers, a technical era, not the cyber tech. nevertheless, it makes one thing very clear. the internet might be pretty resilient malfunctions due to its decentralized infrastructure, but the websites and services we use on not, which can be risky. big tech companies also play an important role in the background. when we're online to facebook as down, you won't be able to log in to other websites using your facebook account either.

in december of 2020 lots of google apps and services went down for about 45 minutes . connected devices like lamps and smoke detectors, also started malfunctioning with the growing number of interconnected devices within the so called internet of things. this will become more of a problem. alexa, look the frankly, but let's take a step back. what about in the next hard way or physical infrastructure? today about 95 percent of international data traffic runs through submarine cables . they connect continents and islands, and they are the reason why this internet access in remote places like small bought in the arctic ocean. what happens when these cables are damaged or destroyed? oh submarine cables are essential for world one access to the internet. some regions are dependent on a single cable, and these can be vulnerable to natural disasters. recently in tonga,

so maybe one cannot option costa for many gibberish option. still a lot of our human ma am naturally packed us in cost. ah, somebody gave a fee. yes. and it's very difficult to repair that you actually need to send out the ship farming out into the ocean. do 1st. oh, kind of be tick. oh, there the fault is located and it pulled cable. oh and then do we pay some part of it? and then they drop it back into the ocean and this can take base 2 weeks. sometimes . ready sandita abdur choti is also researching another natural disaster that could potentially disrupt all the submarine cables on earth at once. solar superstore. so so lots of the strong ac i, diane, the emission of electric and magnetic particles from the sun and, and these are high, eat it actually. so wendy, it isn't the path offer really not stone. ah, this, the magnetic particles from the sun can interact would be, it's more like

a creek and the skin brute comfort already long conduct does on apart from power supply lines. this would also affect underwater cables. but the greatest threat to the internet at the moment our cyber attacks take the warn you crane, for instance, digital warfare was used right from the start. with the help of countless boards, russian hackers are said to have taken down ukrainian government websites, and the ukranian. cyber defense also claims that that countries power supply was attacked in recent years. cyber attacks have increased around the world. ransomware text are the most popular form. here. hackers take down computer networks using encryption software and demand money for decrypting them again, it's a big threat, especially when it comes to a critical infrastructure. august 2020 to the cyber attack. it's a hospital near paris in france. digital patient coils and hospital software cannot be accessed only emergencies can be attended to. july 2021. hackers

manipulate a software update by an american i t provider casea. 1500 companies worldwide are affected in sweden. hundreds of co op supermarkets have to close as or to systems break down may 2021. a cyber attack on u. s. company, colonial pipeline leads to gasoline shortages and parts of the u. s. effecting around $50000000.00 people and major airports, a multimillion dollar ransom is needed to restore the gasoline supply. may 2017, the malware one a cry encrypts user data on computers across 150 countries leading to multiple breakdowns of infrastructure. the spanish company, telephonic, a german rail and french carmen. factual renault are all affected. u. s. companies. cyber security ventures predicts that cyber attacks will lead to

global damages with around 7 trillion, u, as dollars in 2022. for most countries, that's more than that g, d, p, leaving financial demons aside. cyber attacks can also be life threatening. most parts of the critical infrastructure simply aren't adequately protected. how come and what can we do to take this? ah, according to experts, the main reason for weak spots is outdated security systems used by companies. this makes them vulnerable. a lot of critical infrastructure is less mitchell. it's not necessarily big multi nationals. it might be local or regional providers. it's those that are often the most vulnerable as the not able to invest in security and the same way as large scale providers. and that means it's likely that a great number of different types of hacker groups or friends might be able to target them to increase protection against cyber attacks. these weak spots need to

be found and security systems need to be updated regularly. it's also important to detect hacks and malware quickly and to react accordingly. so called ethical hackers can assist in finding weak spots with their know how they can help protect critical infrastructure. we should also, and that we will have agency as part of organizations actually improve security. and there's a lot we can do it. we should feel really empowered by the experts across the globe agree there's cyber attacks on sensitive areas of public life. a real threat, especially considering the current international political situation and more needs to be done to protect these areas. still a complete breakdown of the internet, whether through hackers or other factors is rather unlikely. what's your view on this? are you concerned about internet and infrastructure breakdowns? let us know and youtube, or the w dot com bye for now?
