It's no secret that there are groups actively looking for new exploits and that sometimes vulnerabilities are discovered that become zero days. It's a good bet that police and security services take an active interest in those vulnerabilities when they are found.
But that's very different to claiming the police can easily unlock any device any time they want to and there is a range of private companies around who provide that service to them.
"As with all of the other information these companies store for or about their users, because Apple and Google deliver push notification data, they can be secretly compelled by governments to hand over this information," Wyden wrote.
Then there are all the ways, both white and varying shades of gray, of installing software in the end devices. That's your primary threat right there.
The manufacturer provides the means to bypass many of the cheaper tools, but few people use them.
There are more exotic tools that can bypass security controls. These are more niche and not generally available to law enforcement. There may be some crossover when counter-intelligence interfaces with law enforcement. (Ie. FBI, DEA, RCMP, ICE, etc)
Believe it or not, I actually care about privacy. Innuendo is not my intent, no maliciousness here, only stating there are programs that have access to your data. Telegram/Signal/Encrypted or not. They don’t need access to your device. Only access to the Internet.
For which you have provided not a shred of evidence here beyond the same type of innuendo you've been posting all along - even while implying that some of this is public knowledge that you could therefore cite to establish at least some credibility.
Your claims in combination appear to require that the technical foundation on which almost all serious security on Apple devices is built must be fundamentally flawed and yet somehow this hasn't leaked. That's like saying someone found an efficient solution to the discrete logarithm problem and it's in widespread use among the intelligence community but no-one outside has realised. It's theoretically possible but the chance of something so big staying secret for very long is tiny.
As I said before - extraordinary claims require extraordinary evidence. Thank you for the discussion but there seems little reason to continue it unless you're able to provide some.
It’s not extraordinary if you’re in this space. This is but one of many such initiatives. A few have already been in the works for years.
