This is where we’re at. The responsibility for fighting surveillance abuse falls to tech companies, because nobody even pretends that the Federal government and courts are functional moral actors.
I have to assume that right now Apple and other tech companies are developing procedures to identify subpoenas that are aimed at Congress, on the assumption that the DoJ can’t be trusted to tell them.
“Well, we only handed over metadata, not content.”

You handed over a list that could contain every phone number House Intelligence Committee members ever spoke to or texted with, and you think that makes it ok?
Anyway I just want to say: I’m mad at Apple over this. But I’m also mad at the fact that I have to be mad at Apple.

The people who brought us U2: Songs of Innocence shouldn’t be the only thing standing between us and unfettered surveillance.

Reporters: when Apple says it hands over “metadata”, ask them what the hell that means.
Every time you start an iMessage conversation with someone, Apple logs the phone number. That’s “metadata”.

Did Apple turn that metadata over in this case?
Ok, following some research. It appears there are three orders that courts/law enforcement can use to obtain metadata. This is complex. Sheesh. 1/

“But iMessage is end-to-end encrypted!”
Also I think it’s amazing that in five years we’ve gone from “if you haven’t committed a crime you don’t need encryption” to “US opposition lawmakers have their texts searched.”
Quick reminder: Apple could fix this in a heartbeat by adding an “end to end encryption for iCloud backup” setting (the tech is already in place), but they don’t. Even for those who want it.

Oh wow, how did I miss this one. Tricking browsers into uploading their secret cookies to FTP sites, because the two servers share a TLS certificate.
Really in-the-weeds technical discussion of mitigations by @FiloSottile.
I’m going to forget about TLS here for a moment, and point out that the best way to mitigate a lot of these attacks is just to replace cookies entirely.

Oh good the FBI recovered the Colonial Pipeline ransom by tracing the wallet. Ransomware is solved!
Narrator voice: ransomware was not solved.
Looks like ransomware operators are going to have to do more than, well, the barest minimum in order to protect the privacy of their payments.

The FSB’s encryption software seems to be pretty much in character. krebsonsecurity.com/2021/06/advent…
I know this is a bit of a stereotype, but why is Russian crypto always so weird?
“We don’t use a normal random number generator, we use a gerbil connected to a hot cup of tea. Also use our ciphers where the S-Boxes are ‘random’ meaning they actually aren’t.”

Dear researchers: the hard part of problems like “traceability” is not the part where you build a mass surveillance system. Building mass surveillance systems is *easy*.
The hard part is building systems that don’t utterly shatter the security guarantees that the private system offered, and don’t have caveats like “obviously this can be abused, stopping that is future work.”
When I go out to see what our research community has been doing in this area, I expect them to understand what makes this research problem hard. Not to find slides like this one.
