In practice it was confined to specific TPM modules, but in principle it shows how one flaw in the RNG can jeopardize the whole system.
I also remember seeing a similar vuln in certificates where an attacker _generated_ millions of certs and was able to somehow get the private cert by trying every possible seed for the RNG. (Like seeding every second from 2003-2011 for example, then generating a cert with it). I know I'm getting major parts of this wrong but it conveys the general idea.
Return of Coppersmith Attack is, as the name suggests, a really old attack whose fix has been known for a decades but was missed in certain newer implementations. It does indeed underscore how RSA is tricky and you shouldn't do it yourself. Everything has to go right for it to be secure, unlike something like AES which doesn't have such subtle failure modes.
Blackmail/ influencing elections. Find the presidential candidate's post when he was 14 and said something racist or edgy and use that as leverage or kick him out of the race.
It wouldn't surprise me if it takes more effort to be succinct. There's some famous quote from I think Mark Twain "this letter would have been shorter but I ran out of time". Just my guess
And just like welfare bucks, people will quickly grow accustomed to getting their "intelligence" handed to them from the machine, while their own intelligence atrophies. Breeding dependency
These tips are not complete, but just the problem areas that I think noobs get stuck on:
- understand that different tasks require different amounts of heat. The reason a task is difficult or you ruined a board could be due to your iron not getting hot enough or too hot (traces come up).
- use flux, as others have said
- have proper ventilation, even for lead-free systems, there are plenty of other toxins you are likely exposing yourself to - straight into your lungs - if you solder in an unventilated area. Dont think "it wont happen to me".
- wear eye protection. tiny little beads of molten metal can and do fly up in random directions, especially when soldering wires.
- if you burn yourself, hold the affected area under cold water for 20-40seconds, way longer than you think is necessary. burns keep burning after the heat source is removed.
- get a good soldering iron if you are serious about doing it a lot. I am no expert, but I used a Metcal MX-500 for years. If you can afford it, do it. It was the cadillac of soldering irons. Don't get a $30 RadioShack model and wonder why you can't solder tiny SMT joints.
- get a bright spotlight for doing fine work. to me, the light was more important than magnification. the magnifying glasses just got in the way, and stereo microscopes are probably too expensive for you/most of us.
It's probably a liability from the nudity. Someone says "that's me! I didn't consent to my naked body being posted on the Internet!". Even if it was incidental, but if it was allowed, it would bring about a bunch of perverts a-la "girls done wild: burning man '26".
