My students @maxzks and Tushar Jois spent most of the summer going through every piece of public documentation, forensics report, and legal document we could find to figure out how police were тАЬbreaking phone encryptionтАЭ. 1/
This was prompted by a claim from someone knowledgeable, who claimed that forensics companies no longer had the ability to break the Apple Secure Enclave Processor, which would make it very hard to crack the password of a locked, recent iPhone. 2/
We wrote an enormous report about what we found, which weтАЩll release after the holidays. The TL;DR is kind of depressing:
Authorities donтАЩt need to break phone encryption in most cases, because modern phone encryption sort of sucks. 3/
IтАЩll focus on Apple here but Android is very similar. The top-level is that, to break encryption on an Apple phone you need to get the encryption keys. Since these are derived from the userтАЩs passcode, you either need to guess that тАФ or you need the user to have entered it. 4/
Guessing the password is hard on recent iPhones because thereтАЩs (at most) a 10-guess limit enforced by the Secure Enclave Processor (SEP). ThereтАЩs good evidence that at one point in 2018 a company called GrayKey had a SEP exploit that did this for the X. See photo. 5/

тАЬWe donтАЩt negotiate salariesтАЭ is a negotiation tactic.
Always. No, your company is not an exception.
A tactic I donтАЩt appreciate at all because of how unfairly it penalizes low-leverage, junior employees, and those loyal enough not to question it, but thatтАЩs negotiation for you after all. Weaponized information asymmetry.
Listen to Aditya
And by the way, you should never be worried that an offer would be withdrawn if you politely negotiate.
I have seen this happen *extremely* rarely, mostly to women, and anyway is a giant red flag. It suggests you probably didnтАЩt want to work there.
You wish there was no negotiating so it would all be more fair? I feel you, but itтАЩs not happening.
Instead, negotiate hard, use your privilege, and then go and share numbers with your underrepresented and underpaid colleagues. [тАж]

"we don't negotiate salaries" really means "we'd prefer to negotiate massive signing bonuses and equity grants, but we'll negotiate salary if you REALLY insist" https://t.co/80k7nWAMoK
