|
|
|
|
Der Account hängt an der Sim-Karte
|
|
Die Message History hängt an der Smartphone-Installation
|
|
Die Kontakte hängen an einem funktionierenden Client und lassen sich nicht exportieren, Signal zeigt ja keine Handynummern mehr an
|
|
Über die Signal-PIN könnt ihr nur Profilbild, Einstellungen, und Gruppenmitgliedschaften restoren
|
|
Für die Message-History braucht ihr eine Backup-Datei, die ihr nur auf Smartphones exportieren könnt, nicht auf dem Desktop-Client.
|
|
|
|
Geschichte einer Katastrophe:
|
|
- Signal war auf Android und auf dem Laptop installiert
|
|
- Aus versehen beim Versuch Google-Apps zu entfernen das Handy auf Werkseinstellungen zurückgesetzt
|
|
- Das Backup-Tool (Samsung Smart Switch) hatte entgegen den Erwartungen die Signal-Anwendungs
|
|
- Desktop-Client funktionierte noch. Aber wenn man sich auf Android neu einloggt (geht mit der Sim-Karte ja), hört der Desktop-Client auf zu funktionieren und muss neu gekoppelt werden, dabei geht die Message History und die Kontakte verloren
|
|
- Wir haben mit dem Kommandozeilen-Tool sigtop die Message History vom Desktop-Client exportiert -> Text-Dateien und einzelne Attachments, aber besser als nichts
|
|
- Dann eine Story geschaltet "bitte schreibt mir ab morgen euren Signal-Username, damit ich eure Kontakte wieder habe" (aber manche Leute haben Signal Stories deaktiviert, also Leute einzeln anschreiben wäre safer, das fiel hier aus anderen Gründen weg)
|
|
- Dann neu in Android eingeloggt, die Signal-PIN eingegeben, nach und nach poppten die ganzen Gruppenchats auf, dadurch waren die meisten Kontakte wieder da, aber 3 Jahre Message History waren weg, und manche Kontakte haben sich halt danach nicht nochmal gemeldet.</p></div><div class="bespoke-marp-note" data-index="20" tabindex="0"><p>Eine Person schildert ihr Setup. Wenn niemand das preisgeben will, kriegen sie folgendes Beispiel:
|
|
|
|
- Konni studiert Grafikdesign, ist in einer Mieten-Runter-Initiative aktiv und fotografiert regelmäßig Demos & Aktionen
|
|
- Geräte: Windows-Laptop + Android-Smartphone
|
|
- Messenger: Uni v.a. WhatsApp, privat viel Signal, Politgruppe benutzt Delta Chat. Jeweils auch Desktop-Client
|
|
- Photoshop mit Lizenz über die Uni
|
|
- Passwort-Manager: KeepassXC, wird über Google Drive zwischen beiden Geräten synchronisiert
|
|
- Auf Windows: Firefox mit jeder Menge Lesezeichen
|
|
|
|
Gruppe denkt sich gemeinsam eine Backup-Strategie aus
|
|
wenn sie damit fertig sind, kriegen sie von den Trainis ein Szenario, mit dem sie umgehen sollen:
|
|
|
|
- Das ganze Haus brennt ab
|
|
- Hausdurchsuchung, auf einem der Geräte ist Beweismaterial gespeichert, man will danach (verschlüsselt) Kompliz*innen warnen
|
|
- Urlaub mit der Familie im Ausland, du verlierst dein Handy
|
|
- Du wolltest einen Tails-Stick erstellen, hast dich in der Kommandozeile vertippt, und aus Versehen deine Festplatte überschrieben
|
|
|
|
Am Ende berichtet jede Gruppe was grob ihre Lösung war und wie sie mit ihrer Krise umgegangen sind</p></div><script>/*!! License: https://unpkg.com/@marp-team/marp-cli@4.1.2/lib/bespoke.js.LICENSE.txt */
