there's a lot of people in the west, but it's no more than that. constantine naked day. well, you're up to date here on d. w coming up next is our technology show shift. we're going to take a look at how countries and companies can best protect themselves from cyber attacks. of course is more news on our website, d, w dot com. you can also follow us on social media to where i'll handle is at dw news. my name is jared radian berlin. thank you so much for watching statute. ah, ah, every journey is full of surprises. we've gone all out to give you some tips one day and in the footsteps. all who read reason. i'm in your

northernmost count to please. ah 3 times long, but still very much alive. d w, travel, you'll go to the central hospital in germany. it recognizes where exactly it was fun. i've learned a lot. our culture history. all their d. w. travel extremely worth a visit with phone calls, shopping traffic, nothing works without digital networks. unfortunately, our systems are poorly equipped against hackers. how can you protect critical infrastructure against cyber attacks? that's our topic on shift today. ah,

heck, a ceiling data, installing mall, way even shutting down entire cities. hardly a day goes by without the cyber attack being reported somewhere in the world. experts, one critical infrastructure must be protected. what does that mean exactly? traditionally, such critical infrastructure is built to run autonomy, mostly hospitals, for example, have emergency generators to maintain life support systems during a power outage. but in the last 2 decades, much of this infrastructure has been connected to the internet to function. they need access to servers, and these are located all over the world. it's an invisible network of digital systems that has developed over the years, elements of critical infrastructure and connected even across borders. this means individual components increasingly depend on one another, a wind farm and germany is connected to u. s. satellites, for example,

if the satellites fail, the wind turbines come to a standstill. ah, what's particularly alarming critical infrastructure is not only threatened by individual cyber criminals, state institutions can also be behind the attacks that were also cyber attacks during the 1st days of the war and ukraine. literally, as russian tanks rolling over the border into ukraine, we also saw digital components to the attack, including an attack on a satellite network. one that's even used by weight turbines, in germany. any disruption to be invisible digital connections can result at a domino effect. this can put the critical infrastructure of an entire society at risk. cyber attacks usually don't make a grand entrance. them are quite an inconspicuous, it can escalate in an email on a website can open the door to heck us companies and even government institutions

can be affected in the background into this gain access to further service in the network. only once these hackers take over a large part of the digital structure, they strike openly. this is possible because the digital networks a so large and old methods of cyber security, i'm no longer effective. classic model would be almost like a chest, so with a mo, everything inside would be precious and everything outside will be malicious. this is a mode of the doesn't work in the post covered age where we are connecting from everywhere . the question is no more willing to take her get in because every one knows in a take a, we'll get it. you have to protect yourself. finding out when someone gets in and the best cases finding it out very on a very early stage. but why the attack has seemed to easily succeed in hacking networks. almost every company now has cyber security experts, and they are constantly installing you anti virus software all firewalls. but even the best security measures fail again and again because of the same problem. people

i t experts i've been eclipse, tough a story of the day when hackers shut down the systems in the administration. she supervisors. sabina leaps is the chief digital officer and the county of m had bits of felt. an area between berlin and light safe home to around a 160000 people. in the summer of 2021, the county's administration fell victim to a cyber attack. this visit would be, it was early in the morning at 630 a m, the 1st call reached the i t department, but someone turned on their computer and said, nothing's working here right now. yeah, files are encrypting it vatton home. i was working from home and got a call. i think when i went in, we still assume we have an attack now that will be solved in a very short time. it's in, i had forgotten that i everything will be resolved within the next few days as great as i can pay it. hm. but more cool. started coming in

employees from all over the district complained that their computers had stopped working. the i t expert team such the system and came across a ransom note with them cuz i'm happy to set you up as well as that. that's like i said, we're addressing us personally. and cuz someone had clearly spent time preparing this attacked him. that's when they knew this wasn't just another cyber attack. this time it was really serious. because since at that when the computer, if the i t administrator with all of the rights encrypted itself, that's when we knew we had a problem. the hackers were part of a group called pay all grief. they demanded 500000 euros as a ransom page and the crypto currency manero. the i t manager at the time oliver humph. explains why the district decided not to pay obamacare. but when i

was going over time, we had to ask ourselves, it was okay if we pay the ransom, know people that we really good key them. oh, we knew they had been in our system. oh, but who's to say they didn't put some back doors to attack again and encrypt again . but how did the heck us get into the system in the better? for example, it is no longer possible to fully find out because whether it's the road traffic authority or the registry office, people everywhere look with network computing systems to can access without anyone noticing the various tricks and methods. at the beginning of a cyber attack, intruders try to gain access to the computer network. they use various methods currently so called fishing a most of the most successful trick to access systems. one click on a supposedly secure attachment or link will install malware on a computer. intruders can then still passwords and access codes.

often they disguised themselves as trusted contacts, and lord people into revealing their log in data. this type of credential theft relies on other people's good faith poorly secured servers that haven't been updated with the latest security updates can be an easy way into the network for hackers. once inside, the intruders can spend weeks or even months looking for important information. they look for data so valuable that people would pay money to get it back when they find what they're looking for. they encrypt the data and send a message to their victims, offering a decryption key in return for a ransom. victims are left with 2 options to pay up and trust that they get their data back or to refuse and hope that they can recover some of the hijacked data

and that's not all the heck as often are threatened with double extortion. they don't unencrypted data of their victims, but also publish sensitive information on the dock web. if no ransom is page at the end of 2022 sensitive data from a major, austria and health insurance company ended up on the dock web. personal information was released about policy holders who were treated for substance abuse stds, or abortions. the heck us wanted to pressure the insurance company to pay full, a secured service of large companies can become a threat to individual customers. and this wasn't an isolated case for cybersecurity analyst, karen, ella, sorry, it's a booming industry and it's an industry that has managers, planners, developers, criminal groups, took advantage of the call with demick and the changes to all of our lives, to attack health care institutions, public institutions, local authorities, critical infrastructure around the world as at the mercy of these cyber attacks.

and hackers look for the targets where they expect the greatest profit most in north america and western europe. but also other regions are hit by these well coordinated attacks. in 2019 attackers broke into the network of india's largest nuclear power station. in 2021, an attack on a pipeline provider led to panic, buying and gas shortages in the us. and in 2022, hackers paralyzed the computer systems of the government of costa rica. each of these incidents had impact locally in the country or the region where it happened. however, should an adversary a cyber attack group decide to launch several attacks at the same time simultaneously in many different countries around the low impacts to that would be potentially devastating. can a cyber attack, excess shut down an anti a nation?

as a result of digitization and recent years, some parts of infrastructure have undergone massive changes, and many things can no longer be done without digital systems. now back to our case from germany. how exactly did the attack impact the critical infrastructure? that's not an else like you don't see from the outside. is that the software? if the offices is connected within our i t infrastructure protocol to and nothing works anymore? no cash register software, no alarm system. and in the small county, in the middle of germany, the public infrastructure failed completely. all authorities responsible for around 160000 people had to close. the citizens were worried, elemental attract the florida. hipa wonder can the office to pay out welfare, alimony, or benefits for the elderly? i think he follows that science only very slowly did it become clear what impact a cyber attack had on both the population and the administration. i'll admit that

it looks like a yahoo followed the elevator. we've lost all e mails and the last 20 years, they're all gone and we'll never get them back reading we're little. but how do i explain that to my colleagues and employees? sorry, everything's gone home because many use their e mail system as a filing system and an archive system to store all the emails there. other units of by young to oh my can forget click the situation was so messy that the district declared a state of emergency that normally only happens during natural disasters like huge floods, but not because of a cyber attack. ah, that way the armed forces could send their cyber experts to help the authorities regain control of the network happenstance that really helped us because at the time our i t team did not have enough manpower about the fine that it still took weeks into the authorities were slowly operating again, this had a massive impact on the people in the region. the full car dealership, for example,

couldn't register any new vehicles for a period of 4 weeks as the authorities in question weren't able to work. and without license plates, cars couldn't be delivered to new owners. sales came to a halt, a bitter loss for the company. ah, once as in that quarter, we made a loss of approximately 750000 euros. follow it up. all in all, it took the county about a year to repair all the systems, not to mention the financial damage. the threat of cyber crime is growing. that's why we need to know more about everything that's interconnected in our society. have you ever been affected by a cyber attack? let us know on you to have a d w dot com. that's it from me today. see again, next time, bye. ah ah

. just ma'am ma'am, ma'am. my car is made in germany. for decades they were a symbol of excellence and reliability with what they are glamorous image is getting its blemishes are cost cutting measures and a focus on efficiency affecting quality german cars. when will they lose their sterling reputation? red on d. w, growing up in mongolia. 0 boscoe is 10 years old and loves life in the gobi desert. ah,

me. but she has a dream calling her to leave everything behind in 45 minutes on d. w. story that people the world over information. they provide them the opinions they want to express. d, w on facebook and twitter, up to date and in touch. follow us. from electric tip text to electric ships and old motorcycles. we've got them all. plus we ask like german cars no longer live up to they one standard image now on rev.
