(probably the most downvoted post i’ve made yet on lemmy 😂)

If you’re ready to break free of Android, I would recommend https://postmarketos.org/ though it only works well on a small (but growing!) number of devices.

imho if you want to (or must) run Android and have (or don’t mind getting) a Pixel, Graphene is an OK choice, but CalyxOS is good too and runs on a few more devices.

i guess maybe if you’re using a device with a tiny screen and a lemmy client that doesn’t let you zoom in on images

It’s literally a covert project funded by google to both sell pixels and harvest data of “privooocy” minded users. It seems to be working well.

Is it actually funded by Google? Citation needed.

I would assume Graphene users make up a statistically insignificant number of Pixel buyers, and most of the users of it I’ve met opt to use it without any Google services.

shoutout to the person who reported this post with “Reason: Bot meme, you can’t even read it. whoever replies is a bot too” 😂

E: old thinkpad gang input: take the time to reapply thermal grease to the cpu at some point. It makes a huge difference.

What’s a “gang input”?

😂 it’s an input to this discussion from a member of the group of people (“gang”) who have experience with old thinkpads. and yes, if your old thinkpad (or other laptop) is overheating and crashing, reapplying the thermal paste is a good next step after cleaning the fans.

Indeed, the only thing WhatsApp-specific in this story is that WhatsApp engineers are the ones pointing out this attack vector and saying someone should maybe do something about it. A lot of the replies here don’t seem to understand that this vulnerability applies equally to almost all messaging apps - hardly any of them even pad their messages to a fixed size, much less send cover traffic and/or delay messages. 😦

xzbot from Anthony Weems enables to patch the corrupted liblzma to change the private key used to compare it to the signed ssh certificate, so adding this to your instructions might enable me to demonstrate sshing into the VM :)

Fun :)

Btw, instead of installing individual vulnerable debs as those kali instructions I linked to earlier suggest, you could also point debootstrap at the snapshot service so that you get a complete system with everything as it would’ve been in late March and then run that in a VM… or in a container. You can find various instructions for creating containers and VMs using debootstrap (eg, this one which tells you how to run a container with systemd-nspawn; but you could also do it with podman or docker or lxc). When the instructions tell you to run debootstrap, you just want to specify a snapshot URL like https://snapshot.debian.org/archive/debian/20240325T212344Z/ in place of the usual Debian repository url (typically https://deb.debian.org/debian/).

A daily ISO of Debian testing or Ubuntu 24.04 (noble) beta from prior to the first week of April would be easiest, but those aren’t archived anywhere that I know of. It didn’t make it in to any stable releases of any Debian-based distros.

But even when you have a vulnerable system running sshd in a vulnerable configuration, you can’t fully demo the backdoor because it requires the attacker to authenticate with their private key (which has not been revealed).

But, if you just want to run it and observe the sshd slowness that caused the backdoor to be discovered, here are instructions for installing the vulnerable liblzma deb from snapshot.debian.org.

Sounds like it requires that your DHCP server is hostile, which is actually a very small (though nonzero, yes) number of the attack scenarios that VPNs are designed for

In most situations, any host on the LAN can become a DHCP server.

“there are no ways to prevent such attacks except when the user’s VPN runs on Linux or Android” is a very funny way of saying “in practice applies only to Windows and iOS”.

No. There are certainly ways of mitigating it, but afaict no Linux distros have done so yet.

The vast majority of LANs do not do anything to prevent rogue DHCP servers.

Just to be clear, a “DHCP server” is a piece of software which can run anywhere (including a phone). Eg, if your friend’s phone has some malware and you let them use the wifi at your house, someone could be automatically doing this attack against your laptop while they’re there.

VPNs have several purposes but the big two are hiding your traffic from attackers on the local area network and concealing your location from sites that you visit.

If you’re using a VPN on wifi at a cafe and anyone else at the cafe can run a rogue DHCP server (eg, with an app on their phone) and route all of your traffic through them instead of through the VPN, I think most VPN users would say the purpose of the VPN has been defeated.

because i thought the situation described by the post was tragicomic (as was somewhat expressed by the line from it quoted in the post title)

Color can provide useful context. For example, in the case of this image, imagine if in a thread about it there was some discussion of the ripeness of the yuzu fruit.

Mattermost isn’t e2ee, but if the server is run by someone competent and they’re allowed to see everything anyway (eg it’s all group chat, and they’re in all the groups) then e2ee isn’t as important as it would be otherwise as it is only protecting against the server being compromised (a scenario which, if you’re using web-based solutions which do have e2ee, also leads to circumvention of it).

If you’re OK with not having e2ee, I would recommend Zulip over Mattermost. Mattermost is nice too though.

edit: oops, i see you also want DMs… Mattermost and Zulip both have them, but without e2ee. 😢

I could write a book about problems with Matrix, but if you want something relatively easy and full featured with (optional, and non-forward-secret) e2ee then it is probably your best bet today.
