"It's impossible for two different files to have the same SHA256 hash"
Should I replace this with "nearly impossible"? The problem that while "nearly impossible" is more accurate, it's less precise. Saying "impossible" is less accurate but more precise.
Saying "nearly impossible" vastly overstates the possibility. It's like in Dumb and Dumber "so you are saying there's a chance!!!". No, the chance is essentially zero.
If it's possible, do it.
If you can't do it (and you can't) then it's impossible.
Anyway, I worry about "accurate" vs. "precision".
I'm over 5ft tall. this is 100% accurate, but only about 80% precise.
I'm 5ft 10inches. This is inaccurate, but 98% precise.

I took a long walk around downtown Portland today to check out the post apocalyptic landscape. I don't want to just point the camera at boarded up buildings -- here you can see non-boarded-up businesses across the street from boarded up ones.
It's hard to say which is worse, the pandemic lockdowns or the constant riots breaking windows, but large parts are taking it hard.
Some of the boarded up buildings are proactive to prevent damage, others are boarded up because their windows got smashed, such as this Starbucks, with boards replacing broken windows, but other windows uncovered.
They shutdown pipeline operations to stop the ransomware from spreading. Question: why is the network constructed that allows things to spread? I mention this because the most common question everyone else is going to ask is "How did it breach the perimeter?".
When we get more details, they are going to blame this ransomware on a perimeter breach, like phishing or an unpatched server exposed to the public Internet.
Instead, we need to look at why the internal network allows such things to spread, like Windows networking permissions or port isolation on Ethernet switches.
It’s like in Germany where people are upset at the national curfew — especially the head of their medical institute who keeps pointing out how unscientific it is.
Curfews and mask mandates happen because they are the easiest to enforce not because they are the most scientific. I noticed that in the airport where everyone is masked but nobody socially distances
How it started: This hotel has a TV with a barcode I can scan to control the TV from my phone???
How's it going:
(screenshot edited to remove most of the cookie)
The natural urge of hackers when they see some new networked thingy is to hack it. Simple knowledge of the TV set in the previous screenshot appears to be insufficient to control the TV, I also need the session cookie that was given by following the QRcode.
So what you see in the screenshot is the minimum HTTP request (that normally comes from browsers) that I can craft by hand to change the channel
In first grade, my mom got me a "Brainteaser" book that was way to advanced for my grade level, which I read obsessively, learning such things as the frequency of letters (ETAONS...) to solve cryptograms, among other things.
Both my parents valued learning and were reading books or taking classes all the time. They both inspired me that anything was in my grasp to learn if I tried. So I learned how things worked, including computers.
A lot of hacking is simply taking the time to learn that thing that everyone else believes to be unnecessarily or too complicated beyond their abilities. I took the time.
