Než ten blackout sám v sobě uzavřu…

Kromě toho, že si ČEPS bude muset zamést před vlastním prahem, měli by to samé udělat i TMO a O2, protože během výpadku proudu byla dostupnost mobilních dat a chvílemi i mobilního signálu jako takového velmi, velmi tristní.

Given the recent story about #O2 leaking location information with #VoWiFi #VoLTE

mastdatabase.co.uk/blog/2025/0

I wonder if @osmocom's project to run VoWiFi with Asterisk and a SIM reader makes this all a lot easier, given you don't need a rooted phone any more.

I've been trying to get it to work on GiffGaff which is a UK O2 Owned/Operated MVO so I'm guessing uses a lot of the same infrastructure.

I haven't got it to work just yet but I'm close.

This is something you need to read in order to believe

subject: VoLTE
provider O2 UK
nightmare: infosec

Enormous. Outragerous are some of the words I would use. Take you time to read and learn because they are not the only culprits on the planet with such bad data protection practices

Excerpt

>>

Quite quickly I realised something was wrong. The responses I got from the network were extremely detailed and long, and were unlike anything I had seen before on other networks. The messages contained information such as the IMS/SIP server used by O2 (Mavenir UAG) along with version numbers, occasional error messages raised by the C++ services processing the call information when something went wrong, and other debugging information. However, most notable were a set of five headers near the bottom of the message:

SIP Msg
...
P-Mav-Extension-IMSI: 23410123456789
P-Mav-Extension-IMSI: 23410987654321
P-Mav-Extension-IMEI: 350266809828927
P-Mav-Extension-IMEI: 350266806365261
...
Cellular-Network-Info: 3GPP-E-UTRAN-FDD;utran-cell-id-3gpp=2341010037A60773;cell-info-age=26371

Synthesised excerpt of IMS signalling message for demonstration; not a genuine IMEI/IMSI/cell ID.

Two sets of IMSIs, two sets of IMEIs, and a Cell ID header. How curious…

Sure enough, when comparing both the IMSIs and IMEIs in the message to those of my own devices, I had been given both the IMSI and IMEI of my phone which initiated the call, but also the call recipient's.

Přišlo mi oznámení od O2, že mi zdražují Internet o 50 Kč měsíčně, za 24 měsíců mi ho zdraží o dalších 150 Kč měsíčně, a za to dostanu jejich filtrovací a blokační službu "O2 Security", kterou rozhodně nechci. Nedík, O2...

Vielleicht sind dies für andere Anwender nützliche Informationen. Ich habe jedenfalls lange nach den Einzelteilen gesucht…

Teltarif berichtet, dass o2 seine 5G-Dienste in die Google Cloud verlegen will:
"Wie o2 Telefónica erläu­tert, ist das Feature für die zentrale Verwal­tung des Netzes entschei­dend, damit dieses so reibungslos und effi­zient wie möglich funk­tioniert. Als Beispiele für die Features nennt der Netz­betreiber den Zugriff auf das 5G-Netz, die maximal verfüg­bare Band­breite, den Daten­verbrauch sowie das Roaming in anderen Netzen."

Ich denke das mal weiter: Google (Musk?) entscheidet, wieviele Daten ich verwenden darf.

When I rode to my house yesterday in the afternoon I felt the energy in the street was not right

That was when I was 20 minutes out

At three 🕞 minutes distance I was absolutely certain that a lot was wrong, and I wasn't surprised when I saw the fire trucks close to the houses 🏠 in between the tax office and the brick street.

A massive fire 🔥 which started in an abandoned building {which burned to the ground} hit an apartment building with about 16 units, then raged through a wooden house where an acquaintance of mine lives, levelling that house in minutes. While the fire 🔥 was burning the wooden one story house was also charring the house beside it.

The fire department had experience with a massive fire in my street more than a decade ago, came with everything {twelve trucks including tankers} and they came fast.
Everyone who was living in the apartment building evacuated safely. A woman ♀️ who I know well confirmed that fact.
However my acquaintance was already intoxicated by the fumes and refused to leave the house thinking that the rescue team from the fire department were robbers!
He was standing with a shotgun ready, didn't point it at them, but refused to leave.
The rescue team was forced to leave him behind and he fell unconscious. When they heard the thump of his corpus hitting the wooden floor, they grabbed him and rushed him to hospital, where he succumbed to the smoke inhalation.

So the abandoned building ignited the apartment building which ignited the wooden house which charred the building beside it. In total three buildings burned, two charred and One person suffocated in the ER. The fire was under control within a very reasonable time, given the fact that my fire department does not have the equipment they need to get every year.

My sincerest Thanks goes to the fire rescue team, because without them the whole block would have burned down...
