The developers of the Manjaro Linux distribution, built on the basis of Arch Linux and aimed at beginners, announced the beginning of testing a new service MDD (Manjaro Data Donor), designed to collect statistics about the system and send it to the external server of the project. The author of the MDD intended to enable telemetry by default (opt-out), but the decision has not yet been approved and, judging by the objections of some developers and users, it is likely that telemetry will be offered as an option requiring prior consent of the user (a request to enable telemetry is proposed to be added to the greeting interface after the first download).

The report includes data such as host name, kernel version, desktop component versions, detailed information about hardware and drivers involved, screen size and resolution information, network device MAC addresses, disk serial numbers, disk partition data, information about the number of running processes and installed packages, versions of basic packages such as systemd, gcc, bash and PipeWire.

The sent data is stored on the project server in the ClickHouse database and visualized using the Grafana platform. The IP addresses of users are not stored, and the hash from the /etc/machine-id file is used as the system identifier.

Аccording to the code https://github.com/manjaro/mdd/blob/master/mdd.py#L40 sends everything.

    enable telemetry by default … MAC addresses, disk serial numbers

    Another reason to not use Manjaro. Just use Endeavour instead.

    Edit: I’m not against telemetry pre se. I have the KDE feedback enabled for example but that was opt in and sends no unique data.

          They’ve let TLS certs expire on multiple occasions. They’ve made the decision to enable the AUR in the default installation, which can cause conflicts with out-of-date dependencies because of the delayed release schedule compared to Arch. They’ve shipped software on their stable branch that included unmerged upstream code. One of their developers temporarily broke Asahi Linux.

          I don’t hate the project, but I can’t trust the developers and management.

            They’ve let TLS certs expire on multiple occasions.

            And they told their community to set their clocks back. As a workaround, it will work but all your created and modified data will have the wrong timestamps.

              He’s also a contributor to Asahi Linux. One of his MRs changed the build options that somehow caused it to (IIRC) use mainline Mesa instead of the branch that is specifically modified to work on ARM.

        Why?

        Let me put the question back to you. How do think the uniquely identifiable information will help them improve Manjaro?

        Do you think they’ve got a Russian satellite and will track down your HDD serial number from space?

        No.

        There’s lots of benefits to telemetry.

        As I basically said, if you bothered to read my comment.

      The MAC address is anonymized with sha256, and IP adresses aren’t stored.

        MAC addresses are 48 bit, and half of that is just the manufacturer. So 24 bits really, and those bits aren’t random, I think manufacturers just assign these based on some scheme, like a serial number. Point is you could easily reverse the SHA by brute force.

        You can’t calculate any useful statistic from a hash so literally the only use this would have is some sort of tracking.


        Edit: I just looked up some data and I found someone using hashcat on an RTX 3090, which looks like it can do almost 10000 million SHA256 hashes per second of salted passwords (which are longer than 48 bit MACs, so MACs should be faster). 2²⁴ is 16.8 million, so it’ll take about 1.7 ms per vendor. I found a database with (all?) 53011 vendor ids:

        >>> 2**24 * 53011 / 10000 / 1000 / 1000
        88.93769973759998
        

        Yup, 89 seconds. You can calculate the SHA256 of every single MAC ever potentially issued in 89 seconds on a bog-standard 3090.

          this would have is some sort of tracking.

          It’s right at the top of the announcement, that it’s mainly for more accurate stats on unique users.
          It’s not that I think this is a good idea, because I don’t, but some people are blowing it out of proportions. Especially since this isn’t at all decided. Which I seriously doubt it will.

            You don’t need this to count unique users. You could just assign a random number on install or whatever. Or even more simply, just run the thing once per month, should be accurate enough. Do they expect the software to just randomly spam duplicate reports? Don’t write it that way.

            Best case they don’t care about collecting minimal data and don’t understand that hashed MACs are easily reversible. So incompetent fools with no sensitivity to privacy.

            Maybe this should be Manjaro’s tagline: Not purposely malicious, just grossly negligent and ignorant.

          The point is that it’s a loophole in privacy laws so they don’t have to outright tell people that they collect personal or identifying information. So they can legally mislead people by claiming it’s anonymous telemetry in hopes that users don’t actually look into it or understand the implications.

        I said elsewhere, I hope this is just some way to track changes over time per user.

        But they need to take an anonymous hash of some non changing data or create an install id that is used for this and nothing else (e.g it identifies a unique user but not the person or hardware behind the user).

        Too much identifying info is just pushed around like we shouldn’t care, it’s become a real problem.

        The first three octets of a MAC specify the manufacturer of a NIC chipset. That could come in handy for driver debugging.

        Manufacturers and firmware versions of storage devices? You can make the argument; perhaps it would have helped figure out the SSD firmware bugs years ago.

        But stuff like whether or not you have video capture card or your current system temperature stats? Nah… that’s getting into “identifiable information as toxic waste” territory.

            A MAC address isn’t really unique. Each has six octets, of which three refer to the manufacturer. The other three octets have at most 16,777,216 possible values. That seems like a lot but it really isn’t; a MAC is supposed to be unique on a LAN, not globally. Rollovers during manufacturing happen, and collisions are rare but happen once in a while.

              And still, absolutely no reason to go further then the first octets, to have the vendor and device

    data such as host name,

    Okay why do they need to know that? Why do they need to know if the computer is called “Melissa’s Laptop” or “Workstation 15, Internal security division”? Seems like this kind of data could if stolen be misused and it has minimal legitimate purpose IMO as anyone can put anything as host name and while in organizations it often corresponds to use it doesn’t have to for individuals. Someone could call their machine “Mack’s Porn Rig” and they only use it for doing banking and a little coding.

    kernel version, desktop component versions, detailed information about hardware and drivers involved, screen size and resolution information,

    This all seems legitimate enough, this would be helpful for understanding the hardware their users run on and targeting features or bug fixes.

    network device MAC addresses,

    Not great but there is an argument for it, they could just grab and send the first 3-4 octets which would give them the info they need on manufacturers without getting uniquely identifiable data that along with some of this other stuff is concerning for fingerprinting.

    disk serial numbers,

    Okay, what the fuck. Why do they need disk serial numbers? What possible use is there for that. Those are used for warranty claims and could be used as part of uniquely fingerprinting a computer and person. Not cool.

    disk partition data,

    This is vague enough. I guess one could choose to see this as just info about partitions in use say if there’s also an NTFS partition that looks like a Windows install that would be useful but on the other hand data encompassed within a partition could also nefariously be read as allowing them access to all your data. Partition layout, partition labels, and file systems used on disks available to the system would be a clearer way to put this and erase any doubt.

    information about the number of running processes and installed packages, versions of basic packages such as systemd, gcc, bash and PipeWire.

    All this is also fine just technical data stuff.

    I’ve defended Manjaro many a time, despite the mistakes they’ve made. The main reason for this, Manjaro is the most stable Linux distro I’ve used.

    However, the main reason I ditched Windows as my primary OS was telemetry (and bloat). If Manjaro introduce this, it absolutely must be opt-in.

    I actually contribute to the Steam hardware survey as I want to ensure Valve, but more so hardware manufacturers, are aware desktop Linux systems for gaming and creative work are viable. But it’s my choice to contribute.

    If Manjaro don’t implement this as an opt-in then I’ll be installing Arch. It will be a pain to configure my software again but needs must.

        I mostly used Ubuntu based desktop distros and frequently had issues with the 6 monthly update cycle. Problems with Fedora too. I have not had a single update issue with Manjaro. I often have different distros running in VM’s and whilst Arch has been the most reliable, most are not.

        I also setup loads of Linux servers in my I.T. job that I used to have, so I have plenty experience.

        The bottom line is Manjaro desktop has been ridiculously reliable for me. Therefore other peoples hate of it washes over me and is meaningless.

    This may be illegal in EU if they don’t use opt in. Even then it may be illegal for under 18 year olds to collect MAC addresses and disk serial numbers, as those can potentially be used for identification.

    The data is anonymized, and the IP is NOT stored. So I’m not sure this violates GDPR?

    From the code we can see the machine ID is anonymized, sending only a SHA256 checksum.

    def get_hashed_device_id():
        # Read the machine ID
        with open("/etc/machine-id", "r") as f:
            machine_id = f.read().strip()
    
        # Hash the machine ID using SHA-256 to anonymize it
        hashed_id = hashlib.sha256(machine_id.encode()).digest()
    
        # Convert the first 16 bytes of the hash to a UUID (version 5 UUID format)
        return str(uuid.UUID(bytes=hashed_id[:16], version=5))
    
    

    This makes it somewhat a nothingburger IMO.

      That’s not anonymous, that’s pseudonymous.

      What is the point of this? The machine-id already looks to be some unique random number, so you’re calculating another unique random-looking number from that, might as well use the original number.

      You can’t glean any useful information from a unique random-looking number that would help with developing Manjaro. You can’t calculate any statistics from that. The only use is tracking.

      Edit: And as mentioned in my other comment, reversing the MAC SHA by brute force is trivial, so that one at least (and possibly the other hardware serial numbers they collect) shouldn’t even be considered pseudonymous.

        That’s debatable, and is only based on the claim that it’s just a 24bit decoding that can be brute forced. I don’t know for a fact that it’s true that it can be boiled down to 24bit.
        I checked my own /etc/machine-id, and the folder doesn’t even exist, so what exactly is supposed to be in it IDK. And yes I use Manjaro.

          I edited my comment on your other reply and by my estimation, calculating every SHA256 of all MACs ever potentially issued takes less than 89 seconds on an RTX 3090.

          I also think MACs are (or should be considered) personally identifiable information, since there is potentially a paper trail back to the person who bought it. Plus MACs are not secret information, it’s broadcast on the LAN and for wireless modules over the air in the immediate vicinity (though some systems will randomize wireless MACs for privacy reasons). Privacy-unfriendly software has been known to collect MACs (even from other devices on the network and in the vicinity), so there are already databases connecting MAC addresses with other data.

            calculating every SHA256 of all MACs

            Yes but because I don’t have the folder it reads myself, I can’t see what actually encoded. Are you sure /etc/machine-id is ONLY the MAC address?
