getting war crimes with the help of the international community, such as the international criminal court. there's lots of evidence they can work with. there's documentation, there are what his reports are. cctv footage and satellite imagery. they're determined to get to the bottom of this justice has a long arm and with work that's being done, hopeless, it will prevail. max santa in bucetti crane day, if you're up to date coming up next his dw business with stephen beardsley after so frank with a what people have to say matters to us a little that's why we listen to their stories.

t. c. vulcan also on our show bad news for some american car makers. their electric vehicles won't be eligible for full subsidies under a new us program. i'm seeing busy in berlin. welcome to our show. starting saturday, twitters famous check mark will come with the price tag. the blue tick has been both a status symbol and a way to verify the identity of high profile users. now those users will have to subscribe to twitter blue to receive the mark. in addition, they'll receive more visibility and access to certain features. the move comes as owner ilan mosque tries to boost revenues. subscriptions will cost around $8.00 for individuals and at least $1000.00 for organizations. several large media outlets have already said they won't pay corps on college. as a business professor at mcmaster university, he joins me now for more a gore and thanks for coming to the show. will the value offered by this new blue

check mark including more visibility features like an edit button would outweigh its potential to alienate many users. that's really hard to estimate. that's a hard question that i think even elan must, doesn't know. we do good. some people estimate now that about 500000 people are signed up to twitter blue already we'll see that changes on saturday. does the value of the actual blue check mark potentially sink? then just that check mark if suddenly every one has it. if your user does this makes sense from a strategy perspective. it depends who you are. so if you are william shatner and you're a famous person who's had the check mark already for a long time, it's certainly sinks because then anybody including me can buy the check mark, and now i'm also verified. for him, the value will decrease and for somebody like me would increase or many other users . and i think what's really interesting here is that a person like william shatner has

a lot of followers. and he is what you could almost consider a content creator for twitter. so losing him and other personalities like him over a blue object mark. a verification might not be great for twitter. and so mosque has angered celebrities like william shatner in this whole row over the blue check marks. he's angered researchers journalists, these tend to be the user base for much of twitter. you could say you talk about a kind of painful misalignment, the companies have to go through when they're changing their strategy. is this such a temporary, painful phase that then could lead to something better for this company? a that's exactly correct. so twitter was a not profitable, in fact, they recorded losses for 8 of the last 10 years. and if you look at their financials, a little more conservatively, it could be for all 10 of those years. so something had to change. the 1st thing was, was cost cutting that was kind of the easiest, most short term thing that could have been done. the next thing is

a revenue and we know that revenue decreased because advertisers of flood most recently mosque has claimed. apple has fled as an advertiser. so premium memberships is the next easiest way to increase revenue. i mean, he has a lot of interest payments to make. all right, let's go on college with master university. thank you very much. thank you. russian intelligence services have relied on a private i t company for several cyber weapons, a company whose former workers, in some cases are now employed by western firms. that's according to thousands of leaked documents, which have been analyzed by a consortium of international journalists. the documents indicate that moscow based in t. c. vulcan is developing tools to allow moscow to launch cyber attacks. spread this information and monitor additional sections of the internet. according to research reports, former workers are employed by amazon and siemens among other companies. when marina quote of who is a research assistant at hamburg university of technology and she's looked through

these leak files. marina, thanks for joining us from amazon. siemens, potentially among other companies that these former employees of this russian from working for. want to start with that. how to serve should we be about this? i don't think you really need to be concerned about that because from any from other institutions which also participate in the cyber patients on the side of pressure. and it's also on the employee for a not quite agreed was when they were doing and they found job somewhere else, including the best and companies. so i wouldn't be want to buy those in place because if you think about spice or something like that, those will be much more on speakers. first people. what's the most surprising thing that you learned in these files? i guess i have not learned isn't surprising because i've been studying the russians . i book ration for many years since 2015. i investigated several of those attacks

and incident response. so for me it was rather confirmation of what i already knew . however, i probably would like to emphasize so the summer, the operations to keep abilities rush already process and they keep just developing them for the. so the files which we analyzed, they describe the software and the infrastructure to support the centralized management of such abrasions planning and management. so they say in advance, the information about the vulnerability is about the infrastructure of those organizations in which they have strong interest. and then they store this information there and wait for this information with additional information and then the commanders, because they're talking about me, the nation that sits within me is don't defense or basically it as military. so then the commanders are deciding what to do, went to do with which resources, in which way and what would be the outcome. they also spread those tasks in between regional centers. so this is what the documents that you see mostly about central

a management operation, which is much more concerned in for me that these arguments give us any sense of what particular targets or what kinds of targets these hackers might be targeting when it comes to western infrastructure or businesses? yes they do, and the question probably could be ask like, what do they not target because they target every since. so not only so the most of course, what alarming it's as a critical infrastructure, the target, the telecom, the day with the transportation the target. also, there was democracies, meaning the internet upgrade out to novice internet segment when all their request and responses from the internet go in through their resources. so you can't even trust that what you're asking for is correct. so you already get and distorted information. so they turned in pretty much everything there is not left. are there any lessons here for businesses when it comes to protecting their infrastructure,

or is it just so broad on what they could, what could be targeted or so? yes, exactly. so the question is that they are interested and they're interested to have any organization in the year so that they could use them later. so those are, can, is ation with things like, or why would they be target? oh, you are, you know, and especially what i would say, what they've learned from their war in ukraine is that when they talking about kinetic, we're military war, this is a very fast pace in operation. so the kinetic weapons are used more often when we talked about peace time and conflict time when you know, let political crisis, this is where the side operations will be much more as a support in, in the pressure record. so the same operation, they're even more worrisome and will be likely used in the piece time then in the war time. so every organization is a potential target. when you have, let's say political crisis or 2 governments are kind of some sin like to discuss

any is a musician can be used as a potential target to of the sized pressure or i marina quarter feel at hamburg university of technology. thank you very much. let's go to some of the other little business stories making headlines. russian automaker after voss has sent all employs on leave for 3 weeks. that's due to a lack of parts for its lauder cars. the auto businesses among the sectors hardest hit by western sanctions against russia. most international carmakers have left the country with only chinese brands still present japan as restricting exports to china for 23 items used to make semiconductors. the move follows similar steps by the u. s. and the u. china and japan are key trading partners, but diplomatic ties had been strained in recent years. as tokyo grows wary of bay jeans, growing military and economic power or american car makers have gotten their 1st look at the eligibility rules for new electric vehicle subsidies and some are

disappointed over now, dns quarter on wall street. yes, it sounds like fewer electric models are about to come up, well, less attractive for buyers, frankly. are that there are fewer, they're going to be attractive. what can you tell us about this? well, i mean, it is a rather complicated set of rules. so i mean, you almost need to be a rocket science scientist to find out if you qualify in which model and which does not. so the treasury department came up with a new set of rules so that certain parts for electric batteries and also some minerals, some materials actually have to come from north america or at least from some trading partners. and if not, then certain models do not qualify for the tax credits besides the ruling from the treasury department. there are also some other criteria, so only models up to

a certain price range quantify and also only people up to a certain income level, but no variance. we will be much smarter on april 18th, that's when the ira. so the internal revenue service will tell us precisely which model qualifies for what tax credit these sourcing issues sound like they're going to be a challenge for these companies for a while to come. that is true, but to a certain degree, i mean, that's the intention of the biden administration. they want to get less dependent from china, even though, especially when we talk about those minerals. i mean, most of the refineries for those, they're actually based in china. so it's going to take some time, but that's the intention of the biden administration to it's a good to create some supply chains and in the united states or in north america, and to become less dependent on china. so it might be painful for now. but in the long term, that's at least what the biden administration is hoping for. it will work out

better for north america. interestingly enough, by the way, the stocks of the v carmakers like the river and lucid, tesla, they saw a pretty big again here in the fried efficient. right, that's the one and only in the quarter in new york, we thank you. and that's our show for more on these and other headlines check us out online. d, w dot com slash business. we're also on youtube. under the dw news channel, i'm seeing there's amberlynn lakes water to the point. strong opinions, clear positions, international perspective, president garden able things, announcement that he plans to station tactical nuclear weapons and beta loans has raised concerns about the father escalation. this is the 1st time since the 990
