The VMC certification process includes checking if it's trademarked. That's why the process started with: get a trademark. Also such a check is manual work, so pretty weak.

Of course! In my case avatars can be disabled, it's user preference whether to have them or not. The avatars are also cached for a month or more on the server side, are never requested directly from the client as to expose the user IP, and only ever fetch the root domain to avoid tracking through per user subdomains. Tracking would still be possible if you use a single domain specifically to track a single user, but my thinking is that the chances of that are fairly low. > But what would be actually desirable, is exactly what you wrote - an > implementation not geared towards businesses.

So in the case of a recipient wanting to see avatars, it's still quite nice to have as opposed to no standard at all. A general avatar standard would have been nicer in my opinion. But then, perhaps the big players would not have adopted it because there are no verification benefits? Not sure.

All my emails from GitHub discussions for example have the GitHub logo right now, making individual users not that visually distinguishable. GitHub sends a user header from which I could fetch the associated users' avatar. I didn't know about the X-Face header! Is that something still in use?

Re: [mailop] BIMI boycott? Lookup tool, why we publish BIMI anyway, and intellectual property law considerations
Hey all, > I might have missed something, but wouldn't that be a phisher's wet dream? It depends on the implementation really. A lot of parallels can be drawn to things email clients and other platforms have been doing for years. Email clients have already been using Gravatar, and on almost every social media platform or forum you can set your own name and avatar. It's not much different. > I don't think that the regular user will check if the little extra lock is > there on the icon. They'll see a version of the paypal logo on the phish and > have an extra feeling of safety. Maybe, maybe not. I feel about 70% of all commercial emails in my client have logos. It's essentially same as the sender name being "PayPal". There's really no implicit extra trust about there being a logo in this context. > how the user is supposed to distinguish which avatars are verified BIMI logos, > and which ones come from a totally different source? An indicator. It's probably not as effective as only ever showing BIMI verified, but it's been standard on other platforms for a while now. It's not the solution to all problems, but it does seem like a design pattern that users will recognize. I have not done any user research into this though, this is just my thought process at the moment. > Otherwise, the non-BIMI avatars displayed along the messages, mixed with BIMI > ones, will just facilitate phishing instead of making it more difficult I'm honestly not sure whether that was a great promise to begin with. It's an attractive one, for sure. BIMI being mixed with other avatars was always a thing that would probably happen. Gravatar is already widely used, and Gmail shows avatars for other google users (as far as I know). I've implemented it this way into my client because I liked being able to more visually differentiate emails, and reduce the mental load of having to scan text. It initially had absolutely nothing to do with BIMI, in fact I added BIMI after I added the other sources. But in my case BIMI can still add security through the verification indicator, which I will be adding. I've hidden avatars for messages in the junk folder as well, as a precaution. Anecdotally, none of the mass phishing emails I've received have had the correct logo associated. It's usually compromised credentials without access to the domain, and they don't seem to go through the effort of setting up Gravatar. Of course this really means nothing for targeted attacks by actually competent phishers, but I thought it was fun to see. It's something I wondered about when I started adding the avatars.

Under the assumption that that he MUA will display *only certified BIMI logos* and not any other "avatars" with the emails, ever. How are you going to force MUA developers to do that? Assume the recipient uses a MUA that displays not only BIMI logos, but eg. avatars from Gravatar service as well. The attacker just sets as his Gravatar picture the logo he wants to spoof. Then sends mail to the recipient. Recipient sees a familiar logo (without BIMI being used at all!) and assumes the mail is genuine. As I wrote previously, the only method to prevent this is a (totally unrealistic) *legal prohibition* for MUA developers to display any other images than certified BIMI logos.

Re: [mailop] [E] Re: BIMI boycott? Lookup tool, why we publish BIMI anyway, and intellectual property law considerations
The image has to be specified in the DNS, and it has to be certified w/ a VMC. The VMC certification process includes checking if it's trademarked. So, in order for a trusted brand's BIMI logo to get spoofed, the email would have to be DMARC-authenticated and the logo specified in the DNS would be the one presented to the mailbox provider when they do DNS lookups on the authentication domains. IOW, the only real way to do it would be with account takeovers. If you can hack into the ESP account of a trusted brand, then you can send fully-authenticated email for that brand, with its BIMI logos. The biggest spoofing risk here is with really inclusive SPF records that include an entire cloud SMTP provider's IP ranges, where other senders also send from those ranges, and they can then send SPF-authenticated email w/ a trusted brand's return-path domain, which would then pass DMARC and BIMI. But that's a security risk already, BIMI doesn't make it worse. Cloud SMTP providers need to do a better job of locking down the sending domains their clients can use to prevent that. However, even there, if the DNS accounts of domain owners can be hacked into, authorization of domains can be faked, too. But, again, that's an existing risk, which BIMI doesn't make any worse. -Tim On Thu, Jan 11, 2024 at 2:35 PM Bastian Blank via mailop wrote: > On Thu, Jan 11, 2024 at 01:45:19PM -0600, Tim Starr via mailop wrote: > > To elaborate on Marcel's answer, so he doesn't have to waste time > > explaining it all over again, the "different logo" won't be displayed by > > the mailbox providers, because it's not the authenticated one. > > What prohibits them from making it authenticated?

Every MUA must be able to show whatever it wants. And each one will have its own some design goals. Hopefully sane and consistent, albeit they might end up being chaotic at times. I see how some people may like seeing images along the profiles. I also see the benefit of (configurable) multiple sources for that. For example, Microsoft Outlook shows the profile images from Active Directory. This can be useful for instance for sorting out which guy was each one in a meeting, and makes much more sense to prioritize that over a BIMI logo of your own company, which would be relatively pointless to shown on pretty much every email. But if I have set a photo for that Contact (e.g. a Clown face for my boss), it should be showing *that* (albeit I might face some pushback from my boss or HR if they figure out). It can be useful to show X-Face or Gravatar from certain mails, such as those coming from a (trusted) forum (hint to Louis: it may be useful to be able to configure the images to show for specific senders), But, as Laurent mentioned, this is going to be prone for impersonation, with a goal of leading uers to phishing, BEC fraud, etc. A really important point here is that the BIMI logos themselves *must be validated* by the MUA. I have been looking at the draft [1], and while there are references to a "BIMI Evidence Document", which is supposed to validate whether I am allowed to use a trademarked logo (at an undefined jurisdiction, I was unable to find its specification, it simply says that "These are defined in a separate document". Perhaps Seth can bring some light on this. I think that is an integral part of the BIMI security properties, that it MUST contain both a hash of the allowed logo (or logos), the jurisdiction(s) where it was validated (see below) and the linked sender domains (plus whatever properties that are needed for validate that through PKI). And the receiver steps miss that they MUST compare the logo with the Evidence Document, and reject it if it mismatches. Otherwise, I could register a trademark IOCBYHZ with a random logo, and switch the contents of the url to a PayPal one. People are already registering ludicrous names as trademarks to enter the Amazon Brands program [2]. Registering a trademark and logo, plus acquiring a certificate, for a targeted attack to a company has an higher bar. But a successful CEO fraud could easily make it worth. Not to mention if the goal were to compromise the company, exfiltrate its trade secrets or launch a supply-chain attack. Having the certificate specify on which jurisdiction is the trademark registered would at least palliate “a bit” the known issue of colliding names/trademarks on separate jurisdictions[3][4] by allowing the clients to ignore (by policy) those in shady offshore jurisdictions and, ideally, showing only those pertinent to the user... if the MUA is somewhat able to figure out what "pertinent" means. Would that mean that companies may need to register an international trademark or apply for the same one in different jurisdiction for BIMI to show to their different users around the globe? (along the associated registration and certificate costs). I'm afraid that may end up being the case. Maybe some MUA will overlap a flag onto the trademark, or allow choosing which countries / trademarks it will honor. Although I doubt the users that the feature intends to protect would notice the small differences due, anyway. It's a complex issue with no easy solution. I feel we are back at the all EV Certificates scenario, with all the same unsolved problems.

They can already rip people off, w/out BIMI. BIMI limits their ability to do so in two ways: 1) It raises the cost, because BIMI setup costs more. 2) It makes it harder for scammers to impersonate trusted brands. -Tim On Thu, Jan 11, 2024 at 12:58 PM Randolf Richardson, Postmaster via mailop < mailop@mailop.org> wrote: > > I might have missed something, but wouldn't that be a phisher's wet > dream? > > Indeed, and because the BIMI record references a URI to load the > logo from, so the scammers (spammers, phishers, malware/virus > distributors, etc.) could simply specify a different logo file with a > recognized brand to make their bad eMail appear legitimate. > > > Most spammers know very well how to do a mail with valid DMARC.

Come to think of it, trademarks can also be registered by individuals in at least some jurisdictions, so setting up a company is just one step that could be avoided.

Re: [mailop] BIMI boycott?
You seem to be taking a religious position based on your perception of "need." If this feature is un-needed, why did Google and Yahoo do it? They think their users want it, that's why they spent time building this feature into their UIs, and why they keep it there. Among other things, it serves as a visible indicator of email that is both authenticated and passes DMARC. If you also object to authentication and DMARC, then you're making yourself even more of a minority advocate. I do not expect any such boycott to get widespread adoption.

Re: [mailop] [EXTERNAL] Re: BIMI boycott? Lookup tool, why we publish BIMI anyway, and intellectual property law considerations
Adding to Udeme's comment. There could be other criteria the MBP could use to determine if the message should display BIMI-associated imagery. This could be domain reputation, spaminess, manual validation, and so on. Just because a domain says it wants to use the Paypal logo doesn't mean it will automatically happen, even if they are actually Paypal. I'm not sure we should try to cover the case where the MUA does something outside of spec and/or recommended practices.

And it's clearly visible from the Laurent's mail that if MUAs will display the unverified BIMI logos (and what would prohibit them from that?) the "authentication" factor can be even weaker than with no avatars at all - because user who is convinced that the logo being displayed means that the message is genuine, may not even look at the actual sender field. Also, if a hypothetical MUA displays BIMI logos, but also displays avatars obtained by other means (one of the users in the thread mentioned a MUA he develops that uses eg. favicons, or Gravatar service for that purpose), how the user is supposed to distinguish which avatars are verified BIMI logos, and which ones come from a totally different source? Trying to look at the "broad picture", I realized that the whole concept of BIMI may actually work as designed *only* if MUA developers could be somehow *legally prohibited* from displaying any other avatars than verified BIMI logos. Which not only seems totalitarian in nature, but also politically completely impossible to actually implement. Otherwise, the non-BIMI avatars displayed along the messages, mixed with BIMI ones, will just facilitate phishing instead of making it more difficult. All the manual work on verifying logos and money invested into it will be basically a wasted effort. -- Regards, Jaroslaw Rafa r...@rafa.eu.org -- "In a million years, when kids go to school, they're gonna know: once there was a Hushpuppy, and she lived with her daddy in the Bathtub." ___ mailop mailing list mailop@mailop.org https://list.mailop.org/listinfo/mailop

You could manage that with a wildcard dns entry and check the dns server logs. However, the draft is specified in such manner that the fetching would be done by the MTA, so the BIMI check and fetching wouldn't provide information to the senders.

Re: [mailop] BIMI boycott?
Greetings. What I believe will happen is most non-big mail client apps will support BIMI if they support avatars, otherwise, they won't, cause the arguments on the receiver side are the same for both features. I don't buy the "promoting authentication" argument. There would be a marginal benefit in spreading DMARC via a UI good-to-have feature as a carrot, thus combating phishing, but DMARC doesn't need help spreading, it's become a requirement by the big mail receivers. So BIMI only becomes useful if VMCs are used. Yay, another bureaucracy on top of the certificate issuer and domain registration ones. Even more hassle and expense for small senders. The big mail players will adopt BIMI cause their clients (the marketers) are proposing it. So eventually anyone without a logo next to their mail will be met with suspicion by the users. Have an e-shop but don't have VMC-backed BIMI? You get your logo shown but no blue checkmark on it, uh-oh, now you're in the spam folder, oops. Tough to be you. Eventually, no BIMI = +5% spam chance and life will go on as usual: small mail operators and SMBs will be even less in control of the deliverability of their mailings while the big senders get even more closely coupled to big mail providers. BIMI is trying to do identity. IMO identity will not be solved in mail inbox UIs. It'll come from concerted efforts elsewhere and mail will integrate into that. Regards, G.

Re: [mailop] BIMI boycott? Lookup tool, why we publish BIMI anyway, and intellectual property law considerations
FWIW we went through the trademark process for our logo. It was time-consuming, but straightforward and not expensive. We've deployed BIMI, but with a= as the SSL certificates are still quite expensive; Digicert's BIMI certificate is half-again as much as their EV certificate. If Digicert et. al. offered a combined EV/BIMI certificate (since much of the labor-intensive validation tasks as I understand it are identical for both certs), I think that could be an attractive option for many senders. IMHO the industry has several complementary/overlapping initiatives at various stages of maturity and adoption, all intended to better authenticate senders and prevent domain spoofing. I fully expect there to be friction, resistance and bumps in the road as we all work to minimize illegitimate email -- but despite Google, Yahoo, Microsoft etc. being a major source of the inbound spam that we see tour and our customers' systems, I applaud their efforts to better authenticate senders and prevent domain spoofing. I just wish they would apply the same strict rulesets to their outbound email streams that they are starting to apply/applying to their inbound email streams... Best regards to all, Mark _ L.

If someone, *as a recipient*, likes having avatars next to email, I have nothing against it - but *only if it's totally optional and decided upon by recipient* (and by recipient, I mean the individual person and not the organization that runs the receiving mail server). Then the recipient can choose to use a MUA that supports avatars (of course, there should always be the possibility to turn them off in configuration - which also solves the issue of tracking; if someone doesn't want to be tracked, he/she can turn the avatar support off in options, and their MUA won't fetch any avatar images from any website). But what would be actually desirable, is exactly what you wrote - an implementation *not geared towards businesses*. BIMI is nothing like this, as John clearly explained below it *is and always will be* geared towards businesses. And for me BIMI looks more like push from the *senders* (and in particular, big marketing senders) on people to use the avatars (and use them only in a particular way dictated by big businesses), rather than a response to an *actual need* from *recipients* to use them.

There is a very real danger (and this is even predicted in the document linked in the previous email) that adoption of BIMI by big mail providers will serve as another "antispam" measure; messages having verified BIMI mark would be treated by ISPs as more "trustworthy" and "reputable" than the messages that don't. This would clearly lead to dividing email service in two categories: "first class" would be an email from businesses that are big and rich enough that they can afford having their email BIMI certified, which would give them a kind of "guarantee" for their emails to be delivered to all the big ISPs - and a "second class" consisiting of all the other senders, who lack BIMI verification, and thus can only hope to have luck that their email gets through the filters (which will happen gradually less and less often). As it has happened with DMARC, which also in the beginning - as the document states - was purely optional and meant only for specific, often-phished domains. This is a very bad perspective, and BIMI is in my opinion a road straight to this direction. -- Regards, Jaroslaw Rafa r...@rafa.eu.org -- "In a million years, when kids go to school, they're gonna know: once there was a Hushpuppy, and she lived with her daddy in the Bathtub." ___ mailop mailing list mailop@mailop.org https://list.mailop.org/listinfo/mailop

Nobody else needs any logos, avatars etc. displayed alongside the email headers. That is certainly an overly bold claim. For a lot of people it makes navigating the inbox easier and nicer to look at, it also does make phishing a bit harder. We've yet to see how much harder because the deployment percentage of good DMARC, not to mention BIMI+VMC, is quite low. Also, I see no feasible way - neither now nor in the future - to use it any meaningful way in person-to-person communication, which is the topic OP asked about, and you seem to have ignored it completely in your answer It's not really designed for that. It could happen in the form of adding the logotype OID to S/MIME certificates, but S/MIME is not that far along - the new S/MIME baseline (by the CA/B Forum S/MIME workgroup) is really new, and that's just the baseline. Maybe in the future. Is the goal to make email a closed ecosystem in which only the big players can participate? For context, we at Zone Media have implemented BIMI in our mail server and web email client, we have also published a BIMI record with VMC. I'd say it's far from being something only "big players" can participate in, unless you consider us a big player... Verifying identity is a difficult problem, maybe it doesn't work out in this exact form or way, but it's empirically evident that the problems BIMI tries to address are real. Boycotting it for the cost is as silly as boycotting entire S/MIME for the same reason. smime.p7s Description: S/MIME Cryptographic Signature ___ mailop mailing list mailop@mailop.org https://list.mailop.org/listinfo/mailop
Re: [mailop] BIMI boycott? Lookup tool, why we publish BIMI anyway, and intellectual property law considerations
I might have missed something, but wouldn't that be a phisher's wet dream? Most spammers know very well how to do a mail with valid DMARC. So, now they only need to send a valid mail from any throw away cheap domain and in their BIMI add the logo of paypal? I understand it's not great to have to pay for the verification/certification, but leaving the door open to abuse is a dangerous path to take. Being on the antispam side, I would hate to have to start implementing BIMI spoof checks.

If you need me to send some test messages, please don't hesitate to reach out -- I'll be happy to send a few, or a few dozen, as you need, and from a few different domains so you can see what different logos look like in an Inbox folder. > Groetjes, > Louis > > > Op woensdag 10 januari 2024 om 21:58, schreef Randolf Richardson, Postmaster > via > mailop : > > > We looked into it and publish our own default BIMI record even > > though we didn't pay the enormous amount money required to one of two > > Certificate Authorities. > > > > If anyone is curious to see what the record looks, use this command: > > > > dig txt default._bimi.inter-corporate.com > > > > The results should include: > > > > ;; ANSWER SECTION: > > default._bimi.inter-corporate.com. 3600 IN TXT > > "v=BIMI1; l=https://www.inter-corporate.com/images/logo60bimi-iccns.svg > > [https://www.inter-corporate.com/images/logo60bimi-iccns.svg]; a=;" > > > > It basically just links to an SVG version of the logo from our main > > web site (which is also in the same DNS zone). > > > > Note: The "a=" portion normally includes a URI to what's called the > > "VMC/Assertion record" in the form of a typical .pem file.

If so, please do share a link to it here (or eMail me directly) because I'd be happy to consider including it in the list of eMail client software options that we provide to our users (and also include it in the "Resources" section of the Canadian Lumber Cartel web site). (On PCs, most of our users are either using OutLook, Thunderbird, or our webmail option. A few are using other software, including Sylpheed, Pegasus Mail, and some others I don't recall the names of.) > Just wanted to add that I actually like it for visual clarity.

If you support BIMI with and without the "a=" parameter containing a certificate, that would be fantastic. (You could always indicate with a golden lock in the corner of BIMI logos when they do have valid certificates specified with the "a=" parameter.) > Groetjes, > Louis > > > Op woensdag 10 januari 2024 om 18:18, schreef Jaroslaw Rafa via mailop > : > > > Dnia 10.01.2024 o godz. 11:32:36 Seth Blank via mailop pisze: > > > The hope is that as BIMI gets more widely adopted, the cost (and > > > automation) of the logo validation drops.
