*Mixed Signals*
I don't care much to revisit the Signal fiasco which mainly revolves around unfortunately misguided reporting; mistakes were made with wording and clarity and we need to own them.
however I need to vent out a couple of comments before signing off:
Some have dismissed the article's content as "embarrassing", and let me be clear - I disagree. I am proud of the technical merit in the article when taken in context, which is an educational write-up targeted at forensic examiners, providing transparency about the tools they use.
Cellebrite is not all about code execs, LPEs, trustzone pwnage and crypto flaws. We also reverse engineer file systems and applications and decode their data to make forensic work accessible and defensible, and we do it efficiently and consistently for hundreds of apps.
Story time –
I’m hanging out at Schönefeld Airport waiting for the flight back from CCC. Wife calls, we chat for a few mins and the call disconnects.
I dismiss it with a “oh well, crazy cell tower.”
3 mins later, wife calls frantically: “ARE YOU OKAY?!” 🤔
- “uhh, yeah, what’s wrong?”
- “ok, I just thought you were kidnapped or in some distress. You started repeating your answers very calmly and I was sure you were trying to signal me something”
- “oh wow, that’s pretty crazy!” 😯
We both realize that while I got disconnected, she got a replay using a perfect recording of my side of the call.
We talk about what it could mean and how this can’t be a normal cell network behavior, and we get cut off again. 🤨
