  1. 3G в каждый подвал. Как устроена и как работает фемтосота

    Приветствую всех! Уже не раз я рассказывал про устройство сотовых сетей разных стандартов и годов. Но общим там было одно: базовая станция в любой сотовой сети - достаточно мощное, габаритное и дорогостоящее устройство. Но начиная со стандарта 3G появились их миниатюрные аналоги - фемтосоты. Как же они устроены, что позволяют реализовать полноценную базовую станцию в корпусе устройства, занимающего места не больше, чем обычный Wi-Fi роутер? Сейчас и разберёмся. Заодно узнаем, как они вообще работают, а также немного поговорим о том, почему вам очень вряд ли удастся самим запустить такую штуку дома. Press F1 to continue

  5. On Mobile Phone Security

    #SS7 and #baseband #vulnerabilities

    What about #mobian hardening on a #MechaComet with a cellular hat? Then there's only carrier protocol weaknesses...

    If ISPs use microwave relays (the hated 'air' - remember Max Headroom) and NSA access points, is domestic broadband really secure either? But the cable or fiber doesn't have 'carrier' vulns.

  11. “Android’s defense-in-depth strategy applies not only to the #Android OS running on the Application Processor (AP) but also the firmware that runs on devices. We particularly prioritize hardening the cellular #baseband given its unique combination of running in an elevated privilege and parsing untrusted inputs that are remotely delivered into the device.”

  24. Apple arbeitet seit Jahren an eigenen Mobilfunkchips, etwa in Deutschland. Doch fertig sind die nicht – und werden es wohl auch im kommenden Jahr nicht werden.
    iPhone 15 wohl noch immer mit Qualcomm-5G
  25. :twitter:​ finally seems to be flat-lining, trying out this new mastodon thing...

    #introduction, for peeps I've not met prior via my bird app handle @ntpopgetdope. I'm a vulnerability researcher that's worked in the industry professionally for >4yrs

    My background stems from an obsession with #windowsinternals & the vastly underrated 'HAL.dll'. These days I'm into baseband vuln research working on obscure hardware, architectures & attacks. Love chatting about all things:
    #fpga #uefi #baseband #faultinjection #openhardware #embeddedelectronics #pcbdesign and #cats !

    Currently with the @InterruptLabs crew, a boutique vulnerability research & exploit development firm in the UK.

  26. I’ve heard that the #GSM standard enables carriers to push #baseband updates to users’ devices, and that devices simply trust all towers to have this control. So my theory is that the carrier pushed an update that bricked the GSM modem. Is that possible? I heard from an unreliable source that it’s no longer possible for towers to push updates. Is there a more likely scenario?

  27. Der Konzern beschäftigt Tausende Mitarbeiter in einer eigenen Abteilung für Mobilfunkkomponenten. Doch noch ist Qualcomm nicht eingeholt.
    Eigenes 5G-Modem: Große Herausforderung für Apple
  28. Eigentlich hatten die Streithähne sich verglichen. Doch nun gelang es dem Funkchipkonzern, eine Apple-Patentanfechtung ins Wiederaufnahmeverfahren zu schicken.
    Qualcomm vs. Apple: Patentstreit teilweise wieder aufgenommen
  29. Apple entwickelt immer mehr Chips selbst, ein Mobilfunkmodem ist in Arbeit. Der Konzern will sich so von der Konkurrenz abheben und Abhängigkeiten verringern.
    Produktion von Apples 5G-Modem beginnt angeblich 2023
