So basically google wanted to give this guy nothing. Then he set a hard deadline for disclosure and google managed to buy him for 70k so they could stick with their own deadline.

Or more charitably, by the terms of the program he wasn't eligable for anything, but they gave him seventy thousand dollars out of goodwill and the spirit of the program.

Then they would have done this before the sorta-threat of his own disclosure date.

> During the life of this bug, since the official bug ticket was not too responsive, I sometimes got some semi-official information from Googlers. I actually prefer to only get updates on the official channel, which is the bug ticket and which I can disclose, but since I was talking with some employees, I picked up on bits and pieces.

This is going to be one if the uncounted casualties of a downturn in tech and layoffs. When the organization is in turmoil, and the tenured folks have left out the backdoor, security flaws are going to remain open for a lot longer

My daughter wears earrings, so she never needs a SIM ejection tool. But I keep one on my keyring - amazing how handy it is. (I don't carry a PIN-locked SIM card!)

Why do you need to pop out your SIM so often? Is that an Android thing, or are you actually swapping your SIM all the time?

Can we expect a fix for Pixels outside of the official service window? So 4 or older?

No. "No security updates after X" means no security updates after X. Of course you can install an up-to-date OS, e.g. LineageOS works on the Pixel 4.

"Guaranteed security updates until at least: X" is their actual phrasing.

Earlier quoted context omitted.

Who knows how many bugs live in iOS as well. Security through obscurity (iOS is closed source) isn't usually considered that great a strategy. Besides the whole "can't install user software" issue.

The number of long-running bugs which have been found in popular open source projects suggests that “many eyes make all bugs shallow” should be remembered as an amusing bit of 90s trivia like Swatch Internet Time. What seems to matter more is how many auditors are actually digging in and how aggressively secure coding practices are applied. It certainly doesn’t seem like there’s a big difference between the two in te…

If something isn't being actively attacked, penetrated, scoured over, delved into, fuzzed, and poked at by MULTIPLE EXPERTS IN THE FIELD, you should assume it has several completely bypassing security vulnerabilities.

“many eyes make all bugs shallow” should have always been seen as horse shit. It has the same level of evidence as other linuxy "truisms" like "worse is better" and "everything as text or a file is best"

Heartbleed and shellshock sat right in public eye for quite some time, but it turns out nobody was watching.

What is up with the Pixel specific bugs lately? One would think Google did more QA on their own products than on stock Android but the opposite seems to be the case.

As it says in the blog post (and is confirmed somewhere in the comments here) this is not pixel specific.

Every once in a blue moon when I pick up my locked iPhone (which auto-locks in just 30 seconds) and engage the home button just as the screen comes alive from the gyro sensing movement, it unlocks on its own. It just flashes the PIN dialog and slides right onto the home screen. I don't use Touch ID, and never stored my print with it even once to test the feature/hardware. It's been happening ever since iOS 11, with b…

This sounds like a UI race condition and actually gives me more confidence in the iPhone (unlike the Pixel, the unlock state isn’t tied to UI elements).

Unless of course you can do this long after it locks…
