back to article When ISPs hijack your rights to NXDOMAIN

Virgin Media's UK customers are about to experience a wonderful new service that intercepts unresolvable DNS requests and redirects the user to a page full of ads and search results. It's becoming a frequent trick that ISPs are pulling on their customers, as non-technical executives who could even put the airline industry to …

    Unalienable misrepresentation

    "You see, a free people enjoy certain unalienable rights: life, liberty, and honest NXDOMAIN responses." Oh come on! This is nothing to do with so-called net neutrality. It's to do with

    a) interoperability, which is why we have standards and ISPs need to follow them

    b) an engineering principle called "the law of least astonishment"

    c) our inability to predict the future.

    The first two points shouldn't need explanation. The third one goes: who knows what use will be made of standard (non-existent domain) response codes in some future technical standard? For example, not getting an IPv4 address might cause you to go look for an

    IPv6 address, or the opposite, according to where in the world you happen to live. It's just short-sighted of any ISP to break technical standards in this way.

    Paris, because she tends to take the short view too...

    I know it's hard for startup puppies to remember

    there's a whole rest of the internet out there, champ. port 80 isn't the only one that people look for domains on -- and an opt-out system based on browser cookies doesn't really cut it.

    yammer about "frustration barriers" all you want, but the web is basically the only internet protocol that even pretends to give a crap about letting idiots use it. the rest of us are trying to get work done, and we'd appreciate it if ISPs would stop fucking us.

    also: please stop defending them when they fuck us. thanks.

    The only whining I see is that of the author.

    Breaking standards to make a few bucks is OK because it only impacts a few?

    Did one of the guys from Phorm write this article? Seems like the same logic. And most people aren't worried about their privacy.... Just whiners, right?

    If the results are relevant ...

    "If the results are relevant"

    A big IF, from what I've seen.

    This is just as bad as people who register misspelled domain names and stick a bunch of ads on the page. They are ads! You only get ads if someone is paying for them, so if the site you are looking for is not running ads (on the right ad network) you will not see what you are looking for.

    What if the site is down? Is a bunch of ads going to help you more then an error message? You still can't get to the site.

    You know what happens if you type "google.cmo" with openDNS? You get redirected to google.com (same for any other obvious typo). That is making the web work better.

    There's two kinds of DNS requests

    Maybe they should extend the DNS so that you can query A records as either A or AW (W=web). That way, the web browsers of the world can be patched to query AW records, the DNS servers still treat it as an A query but can return their fancy advertising pages for NXDOMAINs.

    BUT if an application searches for an A record, it gets back what it asked for or an NXDOMAIN. It works for everybody since hijacking domains from non-browsers serves no purpose.

    The internets and the interwebs are different things but even the ISPs, custodians of these things, don't always get that.

    Oh fuck off...

    All your points are correct, except for the general gist of the argument, which is that no one understands, therefor no one should care.

    That is utter bullocks, because when users in my corporation start having weird VPN issues while in the field, because some ISP decided to play silly buggers with their DNS, it comes back to us to support. In this case your damned right that the users don't understand, but they sure will care when they can't VPN in and email their quarterly report!

    And as far as opting out... how can an application developer tell his users they have to opt out of their ISPs proprietary mechanism? And how can the user, when in a hotel for a night "opt out" of their DNS? The internet needs standards to survive, and your readers are the ones that try to keep the damned thing together.

    Ted, your only flaw is that you think your readership shares your apathy.

    Isn't their ad-laden 'host not found' page opt-in? I certainly didn't have to opt-out of it and I don't see no ads.

    And hell, what's the difference if Virgin hijack the no such domain response anyway? 9 times out of 10 a mistyped domain *does* exist with some scum bag typo squatter creaming some cash off it (e.g. thregister.co.uk). I'd rather Virgin made a few pence from the mistyped URL than the scum bag.

    Of course, in the article's author world, everybody speaks English. Me living in another one, I can say that it's a pain to be presented with a page in Chinese. But hey, if I understand the author's drift correctly, if you're not part of an overwhelming majority, there's nothing to complain about. Actually, ISPs could make 70% of their users happy, and that would be fine. Or 80. or 51. Where's the treshold exactly?

    Now, here, if I mistype "google.cmo", here's the very relevant first result. Not.

    It's Baidu providing the answer. And they don't care about net neutrality either: they won't give a result linking to their competitor. So, I don't see how the user will be happy about that?

    More technically, for the geeks amongst us: it's not only "google.cmo" they redirect. They also do it for "localhost". And yes, I've seen buggy applications trying to connect to the ISP instead of 127.0.0.1, which is really unsettling.

    Truth is

    This should be opt-in not opt-out but nobody would bother and they'd make fuck all so the choice is reversed.

    As for OpenDNS Ted, unlike you, they serve a purpose. A service that's configurable and free unlike whatever some twat at an ISP decides everyone should be getting.

    This is extremely annoying.

    Cablevision/Optimum Online started to do this recently. Hijacking DNS links whether they are top level OR subdomains.

    I type in XXXXX.mypersonalhost.com, and my ISP shows it's ads.

    Being technologically inclined, I can block my ISP's DNS servers on my personal pipe (since they haven't yet blocked external DNS), but it's annoying that they are displaying ads on my domain to others.

    Let's not forget that DNS affects more than just HTTP..

    One not so subtle interruption is, since many systems are setup to resolve names using DNS first, connecting to local machines will cease to work using Netbios/SMB name. I used to be able to type "\\Server\Share", but that stopped working with the ISP's ad server taking over.

  12. Iggle Piggle

    If they mimiced OpenDNS...

    ...and offered some protection from phishers and porn then perhaps this would be a nice default situation. However if all they do is convert www.theregister to www.adserve.com them there is nothing in this for the customer and opting out is the only sensible route (assuming that remains an option).

    I have set up OpenDNS for my in-laws and my parents and myself. In most cases it was as easy as going to the router and setting the DNS server to that of OpenDNS. However BT have a funny idea that trying to change the default DNS server is something that only scammers would want to do and so they do not allow it. This forced me to change it in the computer which is not my ideal solution and actually just as possible for the scammers.

    it's not the browsers, it's the DNS

    The issue is *not* with browsers pulling ads out of the void. The problem is that people should be able to, and do, rely on NXDOMAIN. It can make determining the causes of network failures *much* easier. And of course there are already the stories of database corruption based on loading bad data from domains that previously bailed with nx.

    Oh, and while they're at it, are they spoofing an SPF record too? Spammers would be very interested in this - you could wipe out SPF with a few careless strokes, though the big mail providers would likely find a way to opt out. I'd be curious to hear what someone's results are for a TXT record on a fake domain. Verizon is still honoring NXDOMAIN for me.

    But hey, I'd gladly write you a browser plugin that not only would replace nxdomain, but would also replace all HTTP 4*, 5*, 3*, and hell, even 2* error codes with ad search pages. I mean, who cares about all those pesky error codes? HTTP, DNS, what's the difference, right?

    After reading this insane rant against some antagonist I'm not sure exists...

    I feel much saner... all of the sudden.

    Why are both sides of an argument, that matters to almost no one, done with such exaggerated anger? Yet the issue, when explained properly, seems to show that it is a non issue, due to the fact it is too late to do anything about it, one way or another. Net neutrality has never actually existed, and if it did, it was only because the men (and women, in case there were any there at the time, just to be P.C.) who ran the companies that actually own the net were too old to know how to properly exploit its potential to make them more money while giving customers what they want, and that everyone who used the net took this as a conscious act of leaving them alone (which I'm not sure anyone really ever thought, since no one really thought about it).

    Noticing the lack of neutrality is like noticing the sun is up during the day. The lack of there ever truly having been a neutral net makes defining what net neutrality is very difficult, or just wishful thinking, like wanting unicorns to be real again. Instead approaching the issue with the "There's never going to be any goddamn unicorns again you unitards" attitude, sometimes having to repeat oneself using logic and reason will eventually teach the uninformed the truth. Especially in a situation where every month there's a new wave of newbies to the topic, who instead of hearing rational argument, hear people shouting at them that they're stupid the first time they say something that is inaccurate, or even before they have the chance to even learn about it. Who likes going into a room only to immediately have someone point at them and tell them it's people like you who make me so frustrated. The ONLY reason anyone believes the net "should be neutral" is because it sounds good, like having a sunny day every day. But rain can be beneficial too, when it comes to the entire economy that is the internet.

    Sometimes simplifying things too much leaves everyone outside of the informed argument that it should be, and creates opposition where there should be none. And since there's a new misinformed person every day, judging by the crazed frustration of the anti-conspiracy-nut-nuts, the job should be left to those with more patience and the willingness to just repeat the facts and teach the history, and not to those who have obviously run out of the patience needed to help inform those that need it.

    There are no businesses that are neutral, as they all, at the very least, need to try to keep themselves in business, even at the cost of changing how they do business. And that is as neutral as it can ever be because it is also a part of human nature, so while it can be tempered, it will always be this way. The real problem the neutrality topic fails to address, or is avoiding, is that businesses can be very antagonistic towards their customers, usually unintentionally, or because the business has been taken over by complete assholes who hate everyone who isn't like them, which is pretty much everyone. But to throw into it the replacement of an error message with adds, while a little late anyway as all the ISP's where I have lived the last 2 years have been doing this already, is like comparing hunting with genocide. I honestly have yet to see the ISP's get into this neutrality debate in any serious way, so it seems to be mostly average people who are making all the fuss, or it may even be just the fringe loudmouths who believe what they say should be heard by everyone whether they want to or not, like the TV news channels seem to be nowadays. But I realize, pausing to think is very difficult for the modern person, and it's easier to pick sides in a fight that isn't real.

    Of course, if the article is an example of how crazy a small issue can become when it is blown out of any reality based proportion, I missed the punchline, and the sarcasm, and deeply apologize.

    @ Yes Me

    "who knows what use will be made of standard (non-existent domain) response codes in some future technical standard?"

    Hmmm. I'll give you the first two, but the third isn't a great reason not to offer a page of possibly relevant ads instead of a browser error.

    One of the reasons I like Ted is that he's man enough not to begrudge someone making a buck. The ISPs need income from somewhere, especially if you/me/we are going to continue to get uncapped ADSL at less £ than a point to point. And is this service that will make life a little easier for the person who needs a bit of help with the internet anyway (and that guy is the kind of user who probably subsidises yours and mine heavy internet usage). Having said that, I have a large hangover today, and thus am probably wrong.

    "It's one of the many tumors that is slowly killing real liberty: the belief that if you whine about something enough and call it a right, the government will do something, and when they don't, you whine even louder, at which point the general public stops caring about your cause because Global Warming is starring in its very own movie, and dammit, nobody out-whines Al Gore."

    Also, the ISC released the delegation-only patch for BIND in order to neuter sitefinder.

    Boy am I glad I don't use NTL/Virgin/whatever-their-name-is-today for DNS, preferring to run a caching nameserver (in delegation-only mode!) on my own network, which also allows me to NXDOMAIN various domains notorious for hosting ads...

    Ah yes, but...

    Recall that this is one of the ISPs who are apparently congenitally incapable of supplying what the customer is paying for.

    If they can't supply the 20mb/s service advertised all day every day, without odd little excursions into 'fair use' territory and rate limiting, why would I expect them to provide a clean domain resolution service? The correct approach to an unrecognised request is to flag it, not start making assumptions about what the requester really wanted. And surely, are not mass-dumped adverts normally known as 'spam', something expressly forbidden to the ISP's users? But of course, Virgin know best. Obviously these are adverts I *want*, right?

    I don't pay for cable or satellite TV and won't unless and until they decide I can have a completely advert-free stream. Looks like it might be time to start thinking the same about ISPs...

    And on a side note - Charlie Stross (hi Charlie, been a while!) has an interesting discussion regarding web-page inflation here: http://www.antipope.org/charlie/blog-static/2008/05/why_your_internet_experience_i.html - it's a year old, but I can only assume it's got worse since then.

    Missing the point

    The Internet works, and works well given its size, in part because of simple, well understood standards. Any ISP that breaks those standards is pissing in its own well.

    Another factor behind the functioning of the Internet is the large army of admins who spend their time tracing & fixing real problems and really don't need bright ideas from some marketing twerp interfering with core services like DNS.

    @Yes Me... I have to disagree... this is precisely about net neutrality. The network should not interfere with a users traffic (even things like security/malware/spam should be left to the endpoints). To do so pre-judges what a user may want to do.

    I did wonder...

    .... last night I got a VM page for a mistyped URL - was mighty annoyed by the whole affair, I just retyped rather than them getting a click-through, I would have thought they could have warned me about this new "feature" of theirs before implementing it.

    Now I know it's optional, I'm gonna go looking this evening for the option - unless anybody wants to give me the answer (other than dropping cable broadband ofcourse - I can have 20mb cable with a crappy company, or a max of 2mb adsl with few crappy companies).

    I guess it could have been worse - they may have been tempted not to plaster Virgin Media all over the page, and therefore I'd just think it was an updated dns error page from Safari/Firefox/IE or something.

    A very witty peice. However the world is not controlled by the many, it's controlled by the few. So yes most people don't care about net neutrality and what is returned from a miss-keyed domain name, but it is still important. Their may be millions of people who know how to create a website, but their are billions who simply look at them.

    When you think about all the stunts that an ISP could pull, then DNS error re-direction is pretty mild. As techies we should care and we should make a fuss, for the sake of the Internet the way we like it and for the sakes of all those billions of people who don't know why they should care. We are the few...

    IIRC Tiscali tried this a while back, and were eventually forced to back down. At least that's the way I remember it!

    Why should an ISP have a right to fiddle with DNS requests, just to make a few pence? If the user is too plain stupid to work out that they got an error because they typed google.cmo then their ownership of a PC is probably a danger to everyone else.

    Standards exist for a reason, and no ISP should piss around with them. OpenDNS doing it is one thing, after all you sign up to the service knowing they do it, but for an ISP to change the way they operate?

    And what's going to happen when Joe Average starts typing Google into his address bar, and gets a drop down list of every google related typo he's made recently?

    As Ted mentioned, it has an effect on software that relies on DNS fidelity, why should users have to put up with the fault, and why should developers have to find a workaround to cope with an ISP who's not complying with standards?

    Not that any of this is too big a surprise, Vermin Media were looking at Phorm, so the changing of a few DNS replies probably isn't that big a deal to them.

    Interesting timing on this article!

    I've just spent 2 weeks trying to fix a collegues laptop as he was unable to correctly resolve our internal IP address when connected remotely via VPN.

    I eneded up wiping his machine down and rebuilding it hoping it would clear the problem.

The number of hours and thus money that have been wasted sorting this.

    In defense of OpenDNS

    They offer a content filtering service for free so you don't have to see naughty sites if you set it up for that. I have only noticed their advertising a couple of times since I used it and even then the correct result that I wanted was top of their suggestions.

    To do this on an ISP level seems to be taking the mickey. Customers are already paying for the service, why are the ISPs then lumping advertising on top of it? If we take a TV metaphor, people pay for a service and the TV channels support themselves through advertising. Websites already support themselves through advertising, so if ISPs introduce this "service" will we see our subscription fees reduced?

    Compromise

    I would guess most nxdomain errors are a result of a user mistyping into the browser address bar. A solution would be the ISP sends DNS rcode 3 nxdomain to browser as would be expected when complying with standards, then a timed Javascript redirect shows a page of domain names which relate to the mistyped address, along with all those revenue creating advertisements... Just a thought

    Perhaps if one is not smart nor dexterous enough to type an address correctly one deserves a page full of ads? ;-)

    I think I'll take a piss through Teds Letterbox

    I'm sure there might be some rules against doing that sort of thing but fuck that. It's not as if it's going to affect that many people. In fact it's only going to affect Ted who is prone, at times, to being a whining shit so it's not as if anyone would notice much difference there. I'll even give him the chance to opt-out if and when he works out that having someone piss through his letterbox is actually a value added public service rather than someone just randomly pissing through his letterbox. Just think, if I did not piss in Teds letterbox I'd end up pissing in the street and that's going to upset a lot more people. Of course then he will have to find out how to opt-out and, if I bother to read his request, I'd get around to processing it some time next year. Oh and don't give me no crap about pissing in toilets being standard practice. That smacks too much of 'standards' as if anyone would think standards are important. Fuck, since I'm a generous sort of person I'll also shove some leaflets advertising cleaning products for piss sodden doormats so Ted can tidy up afterwards.

    Just opted out...

    I've just opted out (not that I've seen it yet) and got this message...

    "You have successfully switched off advanced network error search.

    This will apply to all computers on this internet connection, but you may have to opt out again if you replace your modem.

    You can switch this service back on at any time by going to virginmedia.com, and then looking for the links to Advanced Error Search in the My Virgin Media section of the site.

    The Virgin Media Team"

    So it looks like I'm opted out for all machines that use my Virgin Media broadband (not that I use their DNS anyway), so it appears to be a setting that is fixed with the modem (maybe the modem dishes out two sets of DNS addresses, one that goes to this new page and one that doesn't), or possibly it goes on the modem MAC address.

    Still I think that if any ISP pulls a stunt like this they should inform EVERY customer in advance by snail mail and give them a clear and easy to enter link to go to (such as www.virginmedia.com/advancedsearch or something like that.

    Doubt it'll happen though, I mean that would cost them money, I guess they think it's better to just do it and let the customers find the link themselves.

    > What's broken? Who cares? and just what the heck is NXDOMAIN and why should *I* care as an average end user?

    If you put an incorrect server address in any other program apart from a browser, it doesn't understand that Virgin's advertising page is an advertising page and returns a misleading error which the average end user will probably have more problems sorting out than they would if Virgin stopped twitting around with DNS.

    E.g. See what an e-mail client says if you configure it with wrong server address in under Virgin broadband.

    OpenDNS and Virgin... why the distinction?

    "The difference of course is that OpenDNS customers sign up for this service knowing full well that the company does this."

    I have a credit card, and periodically they send through a note about changes to the Terms of the service. If I decide I don't like the changes they've imposed, I'm free to switch to another card.

    OpenDNS might have introduced the ad-serving before you signed up... but Virgin are doing this now. Deal with it.

    As much as we might dislike it, Virgin are free to change the Terms as they see fit, given that they supply the service and, as such, dictate the Terms of the service offering.

    If their customers dislike it, they can vote with their feet. And if enough do, Virgin might rethink the change.

    Of course, I can be this detatched as I don't use Virgin :)

    Still, this piece has prompted me to be amused for, ooh, several seconds by typing google.cmo into Safari, receiving in return the following:

    "Safari can’t find the server.

    Safari can’t open the page “http://google.cmo/” because Safari can’t find the server “google.cmo”.

    You can use Google to search the web for this text."

    Followed by a nifty little search box pre-populated with google.cmo. So I clicks it and Google manages to return a whole page of results, precisely, erm, none of which are www.google.com. Although when I get as far as page 2 of search results, then scroll aaaall the way to the bottom, Google wonders if maybe I meant google.com. So I clicks that and finally get a page of links to Google stuff, none of which are actually search...

    All other arguments aside, this is really fucking spectacularly useless...

    "If I type in "google.cmo" accidentally, and am presented with a link to Google, then the ISP has just made my day easier. Who cares if they get paid for that click? It makes the internet work better for users."

    All that does is condition the user to believe that they can ham-fist their way through the internet without bothering to check that they typed the right address in and that they can then click on some link which takes them where they really meant to go.

    That sort of carelessness will eventually lead them somewhere which is a real, registered domain serving up a double dose of malware, and now they're owned again. Gather a few thousand of those together and you've got something which makes the internet work WORSE for EVERYONE.

    In the USofA, COMCAST is poisoning their customers DNS too

    COMCAST in the United States - at least in Ann Arbor, MI, is doing the same thing. They're redirecting to some company called FASTSEARCH.NET, although they're redirecting only names that begin with "WWW." and end with a valid TLD.

    They have an opt out page too. You have to be using their service and know the MAC RF ID of your cable modem (which ought to be printed on the thing anyway.)

    Late Sunday, I did the opt-out. They processed it this morning (Tuesday).

    Nevertheless, I'm thinking of querying the root name servers directly. If enough people do that, the root nameserver people will start gnawing on COMCAST for this bit of evil mindedness.

    P.S.: I'm blocking FASTNET's net-block , 208.68.136.0/21, in my home router/gateway. I tend to take an aggressive view of people attempting to abuse my system, and so most of Vietnam is blocked as well as major parts of China. And various parts of the American South and West...

    On many networks, the name resolution for local servers will break as well, at least when DHCP is configured to use the ISP's DNS.

    This can break file shares, VOIP, databases, VPN, ...

    It's not a non-issue because it's not just port 80.

    Even if it were just HTTP, who are the ISP to redirect to ad sites? If their business model is not economically viable with paying customers, then charge more or make way for those who have viable models.

    A note from a crusty old dialup user

    Still got this account from years ago, back when it was called "Surfunlimited" and came from a company called Blueyonder. I get proper DNS errors (or at least, my SQUID server tells me it's getting a proper DNS error), no bullshit redirects, and the link at https://my.virginmedia.com/advancederrorsearch/settings tells me I have to be a Virgin Media BROADBAND customer.

    I guess this is one of those rare occasions when I can pat my trusty external v90 with its serial port comms and blinkenlights and say "good boy". Well, that and being able to circumvent IP bans with a simple redial. Not that I'd ever do that.

    @HUH? By Stuart Boston

    DNS responses tell your computer where the host/server you were looking for is located. When these DNS record responses are changed (from NXDomain or non-existent domain to name exists) they cause whatever application made the DNS request to attempt to communicate with whatever machine the falsified record points to as if it was the intended recipient machine.

    If you try to send an email and your ISP hijacks the DNS request your email still gets sent, but it goes to the ISP's ad server.

    When you attempt to login to a domain based system who's DNS record was hijacked your login credentials get sent to the ad server, not a legitimate recipient.

    When you try to print to a hostname based print server and the print queue's DNS record (or lack thereof) gets hijacked , your computer still sends the document to be queued (because it thinks it's found the printe queue) but instead the document gets sent to the ad server.

    If all of this is new to you then your "15 years" of "IT" must have been with DOS boxes or something and you should really try looking up this stuff on wikipedia or try looking at the resources the the previous commenters have pointed out.

    Could someone exploit this?

    I'm a little late to the party on this one, and know near to nothing about DNS. However it strikes me that Dan's internet breaking attack exploited Betwick filtering and blitzing transaction IDs in order to work. This was said to be marginally nullified by DNS caching, however if I therefore try to go to a DNS server which is feeding its DNS off virgin media's DNS servers, would accessing XXXXXX.uncached.co.uk, cache the DNS for uncached.co.uk as being their ad server?

    No flaming please, as I said I know that I don't know what I'm talking about. My point is not that such an attack is there, just that we didn't see the previous attack, and it would be a lot harder to defend against future attacks if people are pissing about with the rules.

    Rogers started this about a year ago. Previously my poorly typed URLs when unresolved would be redirected to Google and the one that I meant to type would usually be on the top of the list.

    Then one magic day I got a Rogers/Yahoo ad list. I could opt out with a cookie. When you did this you would get a Rogers/Yahoo 404 page with an option to resubscribe to the ad list.

    With that and them packet shaping my VPN connection to the office (2 MB transfer in 15 mins on a 6 Mbps line) I switched ISPs.

    Funny thing is they promote both of these network management techniques as a way to improve overall customer satisfaction with the internet experience.

  • It's a crime to use Google Analytics, watchdog tells Italian website
    Because data flows into the United States, not because of that user interface

    Updated Another kicking has been leveled at American tech giants by EU regulators as Italy's data protection authority ruled against transfers of data to the US using Google Analytics.

    The ruling by the Garante was made yesterday as regulators took a close look at a website operator who was using Google Analytics. The regulators found that the site collected all manner of information.

    So far, so normal. Google Analytics is commonly used by websites to analyze traffic. Others exist, but Google's is very much the big beast. It also performs its analysis in the USA, which is what EU regulators have taken exception to. The place is, after all, "a country without an adequate level of data protection," according to the regulator.

    After offering free G Suite apps for more than a decade, Google next week plans to discontinue its legacy service – which hasn't been offered to new customers since 2012 – and force business users to transition to a paid subscription for the service's successor, Google Workspace.

    "For businesses, the G Suite legacy free edition will no longer be available after June 27, 2022," Google explains in its support document. "Your account will be automatically transitioned to a paid Google Workspace subscription where we continue to deliver new capabilities to help businesses transform the way they work."

    Small business owners who have relied on the G Suite legacy free edition aren't thrilled that they will have to pay for Workspace or migrate to a rival like Microsoft, which happens to be actively encouraging defectors. As noted by The New York Times on Monday, the approaching deadline has elicited complaints from small firms that bet on Google's cloud productivity apps in the 2006-2012 period and have enjoyed the lack of billing since then.

When these concerns were reported to a manager, Lloyd was told to drop the issue or risk losing his job, it is claimed.

    RCS Labs customers include law-enforcement agencies worldwide, according to the vendor's website. It's one of more than 30 outfits Google researchers are tracking that sell exploits or surveillance capabilities to government-backed groups. And we're told this particular spyware runs on both iOS and Android phones.

    We understand this particular campaign of espionage involving RCS's spyware was documented last week by Lookout, which dubbed the toolkit "Hermit." We're told it is potentially capable of spying on the victims' chat apps, camera and microphone, contacts book and calendars, browser, and clipboard, and beam that info back to base. It's said that Italian authorities have used this tool in tackling corruption cases, and the Kazakh government has had its hands on it, too.

As of January 2023, Chrome will stop running extensions created using Mv2, with limited exceptions for enterprise versions of Chrome operating under corporate policy. And by June 2023, even enterprise versions of Chrome will prevent Mv2 extensions from running.
