all right, let's take a quick look at all the bundles league a result after saturday's games. so last place, sean congress, victory against stood guard. there are those dormant in leipzig, wins. vols for ve to cologne. hair to berlin. defeated outs berg. breyman took care of bo home, and on friday minds hammered. glad bah! and coming up later on sunday, fryeburg face liver cruising and then by him unique take on when you're in berlin in a battle for 1st place here. after data dw new, i'm married ever seen from me and the entire team in berlin. thanks for watching. ah, every journey is full of surprises. we've gone all out to give you some tips with the footsteps. recruitment,

i'm in your northern most count please. ah 3 times along past, but still very much alive, that when you travel, you'll go to the central hospital in germany, europe. i recognized where exactly was fun. i 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 malware, 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 is developed over the years, elements of critical infrastructure unconnected 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, did so called buttons 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 in 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 a callous click 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, to 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 would be malicious. this is a model that 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 will get. you have to protect yourself finding out when someone gets in and the best cases finding adult very on a very early stage. but why do a tech has seen to easily succeed in hacking networks? almost every company now has cyber security experts. and they are constantly installing new anti virus software all firewalls. but even the best security

measures fil, again and again, bixler at 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 creeps is the chief digital officer and the county of on the 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 message will be, it was early in the morning at 6 30 am the 1st call reached the i t department where 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. in i had forgotten that i, everything will be resolved within the next few days, or treatises could pay at 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 knows them cause i'm happy to set you up as well as that. like i said, we're addressing us personally and cuz someone had clearly spent time preparing this attack them. 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 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 ma nero, the i t manager at the time oliva humph. explains why the district decided not to pay with it. but when i was going over time, we had to ask ourselves,

it was okay if we pay the ransom, know we would we really get a 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 creep again? but how does the heck us get into the system? in the benefit example, it is no longer possible to fully find out. because whether its the road traffic authority or the registry office, people everywhere work with network computing systems to can access without anyone noticing the various tricks and methods. at the beginning of a cyber attack, intruders tried again 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 nor 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 were 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 is often threatened with double extortion. they don't on encrypt the data of their victims, but also publish sensitive information on the dock web. if no ransom this 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 policyholders, who were treated for substance abuse s at eith. i abortion. the heck i wanted to pressure the insurance company to pay, hold a secured service of large companies can become a threat to individual customers. and this wasn't an isolated case for cyber security analyst. karen ellis, sorry. it's a booming industry. and it's an industry that has managers, planners, developers for criminal groups, took advantage of the call with them make, and the changes to all of our lives, to attack healthcare institutions, public institutions, local authorities, critical infrastructure around the world is at the mercy of these cyber attacks.

and hackers look for the targets where the expect the greatest profit most in north america and western europe, but also other regions a 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 like to panic, buying and gas shortages in the u. s. 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. the impact to that would be potentially devastating. can a cyber attack, extra shut down an anti a nation?

as a result of digitization and recent years, some pots 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 attack they forwarded. hipa wonder can the office to pay out welfare, alimony, or benefits for the elderly. and 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's not spots at yahoo folded elevate. we've lost all e mails and the last 20 years, they're all gone and we'll never get them back released. 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, if by young to oh my, can forget click the situation with so messy that the district to create 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. shuttles fans that really helped us, because at the time our i t team did not have enough manpower about be fine. it still took weeks until 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, ah, once is, and in that quarter we made a loss of approximately $750000.00 euros. follow it up, all in all, it took the county about a year to repair all the systems, not to mention to 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 effective by a cyber attack? let us know on youtube or d. w dot com. that's it from me today. see again, next time, bye. ah a help

. ah. hello and welcome to the 77 percent. in addition, we're going to talk about love relationship and of course break. we also wanted to find out what the full to we tell them and what makes relationships, why he lets me be me. and i, let's see here with the 77 percent on d. w. well, cards are made in germany for decades. they were a symbol of excellence and reliability with what they are glamorous image is getting its blemishes or cost cutting measures and

a focus on efficiency affecting quality german cars. when will they lose their sterling reputation? red? 60 minutes on d w. a . what people have to say matters to us. i am. that's why we listen to their stories. reporter every weekend on d. w. hello and welcome to the 77 percent. my name is edith kimani and i'm coming to you from the heart of no ruby in the special edition of the 77 percent. we're going to talk about love relationships and of course.
