For those of you who haven't seen yet, AT&T recently informed customers of a breach.
Some quick facts about the AT&T breach:
- Impacted over 70 million customers.
- Revealed the call and text meta information. I'll add to this point because I've seen some misinformation showing that content (ie: messages) were compromised. This is not correct.
- The meta information involved not just AT&T numbers, but also numbers associated with those AT&T numbers (ie: contacts who conversed through phone calls/texts).
- The compromise period was during a few months in 2022.
- Unfortunately, there was a delay in releasing that there was a breach.
Unfortunately, there's quite a few ways that hackers can use this information. One big cost to this is that it expands hacker's linkability with your information. If you're wondering how hackers can use linkability, I wrote a post for OSINT called Why everyone is panicking over linkability.
