An official FBI document dated January 2021, obtained by the American association “Property of People” through the Freedom of Information Act.

This document summarizes the possibilities for legal access to data from nine instant messaging services: iMessage, Line, Signal, Telegram, Threema, Viber, WeChat, WhatsApp and Wickr. For each software, different judicial methods are explored, such as subpoena, search warrant, active collection of communications metadata (“Pen Register”) or connection data retention law (“18 USC§2703”). Here, in essence, is the information the FBI says it can retrieve:

  • Apple iMessage: basic subscriber data; in the case of an iPhone user, investigators may be able to get their hands on message content if the user uses iCloud to synchronize iMessage messages or to back up data on their phone.

  • Line: account data (image, username, e-mail address, phone number, Line ID, creation date, usage data, etc.); if the user has not activated end-to-end encryption, investigators can retrieve the texts of exchanges over a seven-day period, but not other data (audio, video, images, location).

  • Signal: date and time of account creation and date of last connection.

  • Telegram: IP address and phone number for investigations into confirmed terrorists, otherwise nothing.

  • Threema: cryptographic fingerprint of phone number and e-mail address, push service tokens if used, public key, account creation date, last connection date.

  • Viber: account data and IP address used to create the account; investigators can also access message history (date, time, source, destination).

  • WeChat: basic data such as name, phone number, e-mail and IP address, but only for non-Chinese users.

  • WhatsApp: the targeted person’s basic data, address book and contacts who have the targeted person in their address book; it is possible to collect message metadata in real time (“Pen Register”); message content can be retrieved via iCloud backups.

  • Wickr: Date and time of account creation, types of terminal on which the application is installed, date of last connection, number of messages exchanged, external identifiers associated with the account (e-mail addresses, telephone numbers), avatar image, data linked to adding or deleting.

TL;DR Signal is the messaging system that provides the least information to investigators.

** week notes **
Last year I set out to rekindle my reading habit. That went well. This year’s reading has been enjoyable, but I’m not cozy with the ratio of non-fiction to fiction I’ve read this year…non-fiction (especially of the computing persuasion) far out balances the fiction I’ve read. I think this is mostly because I’ve been mired amidst a fiction book that I’ve found to be a slog…but enjoyable, too. I’d have abandoned it and moved on, elsewise. Onward!

Lindypress Bug Fix
Just a brief note that for the past couple of days, you might’ve been unable to buy books on LindyPress.net if you are in the United States, Canada or Australia (which is a lot of you). This has now been fixed, so you can place your orders now!

The issue was that there was a silent API update that kept addresses from validating states and provinces. Note that if your order placed, it’s all okay, this is only for people for whom the site would not let place an order.

At the start of this year I set out to revive my long dead reading habit. After having kids it fell by the wayside. I’ve read 41 books so far this year. Mostly a mix of science fiction and nonfiction computer science books. Here’s the complete list of everything I’ve read. I’ve got mixed feelings about keeping track and sharing cou … ⌘ Read more

Alright, check this out. I just kinda completed today’s project of converting a jeans into a saw bag. It’s not fully done, the side seams on the flap need some more hand sewing, that’s for sure. No, I don’t have a sewing machine. Yet?

Image

At first I wanted to put in the saw on the short side, but that would have made for more sewing work and increased material consumption. As a Swabian my genes force me to be very thrifty. Slipping in on the long side had the benefit of using the bottom trouser leg without any modification at all. The leg tapers slightly and gets wider and wider the more up you go. At the bottom it’s not as extreme as at the top.

The bag is made of two layers of cloth for extra durability. The double layers help to hide the inner two metal snap fastener counter parts, so the saw blade doesn’t get scratched. Not a big concern, but why not doing it, literally no added efforts were needed. Also I reckon it cuts off the metal on metal clinking sounds.

The only downside I noticed right after I pressed in the receiving ends of the snap fasteners is that the flap overhangs the bag by quite a lot. I fear that’s not really user-friendly. Oh well. Maybe I will fold it shorter and sew it on. Let’s see. The main purpose is to keep the folding saw closed, it only locks in two open positions.

Two buttons would have done the trick, with three I went a bit overkill. In fact the one in the middle is nearly sufficient. Not quite, but very close. But overkill is a bit my motto. The sides making up the bag are sewed together with like five stitch rows. As said in the introduction, the flap on the hand needs some more love.

Oh, and if I had made it in a vertical orientation I would have had the bonus of adding a belt loop and carrying it right along me. In the horizontal layout that’s not possible at all. The jeans cloth is too flimsy, the saw will immediately fall out if I open the middle button. It’s not ridgid enough. Anyways, I call it a success in my books so far. Definitely had some fun.

I didn’t get around to blogging about the fact that Miniflux recently got a new version. With it, if an entry doesn’t have a title, it finally shows a snippet of the content instead of just the URL as the title. A great new feature if you follow a lot of micro blogs. Regarding micro-blogs, I’m also in the process of reading Manton Reece’s book draft. ⌘ Read more

Peter Saint-Andre: Philosophies and Ways of Life
In his book What Is Ancient Philosophy?, Pierre Hadot almost singlehandedly resurrected the ancient conception of philosophy as a way of life. Consider this observation about the philosophical schools of Greece and Rome: “For us moderns, the notion of a philosophical school evokes only the idea of a doctrinal tendency or theoretical position. Things were very different in antiquity. No university obligations oriented the future philosopher toward a specific school; instead, the futur … ⌘ Read more
