Most linux distributions can be run on read-only filesystems (same as from cd) BUT the only true security hole is running them as root, because volumes can be remounted in rw mode on the fly. I'm using this strategy on my raspberryPi that is running the game console emulators for the kids. They don't do no shutdown, they just pull the plug/wallwart. Roms are stored on etx4 USB, mounted read-only. This one is just mounted in rw mode on the PC, to manage the roms and emulator binaries.

Just make sure you run linux as unprivileged user. Privilege escalation is a thing though, but unlikely on patched systems. However, when you're not connected to the net, i doubt there is a fair chance of catching a successful exploit via USB.

Again, your postulated security described above is utterly dependent upon the rando USB device implementing only a storage class endpoint.

Whatevs. Good luck with that.

I would care less if i am running as unpriv. user on a system that is not network connected. I didn't mention that i'd never use a host with actual user data on it. I thought that would be clear because i was replying to Dabs' "frozen sysimage" approach. I would definitely not use a guest VM but a dedicated box that i can reset via dd or similar disc imaging tools, i wasn't clear on that, as i just recognize while typing this.
And yes, it's part of the very basics: there is no 100% security, only 100% security against certain (and therefor known) attack vectors.

I’m gonna say this one last time. Your postulated recovery is weaksauce against anything other than a disk-resident vector.

dd ain’t gonna do nothing for you if malware-containing USB infects the BIOS.

my bios has a reset to default button for times it all goes wrong. dont conflate things to 2 options when there are many more possibilities

I am not limiting things to two options. I am merely pointing out a single issue with the postulated ‘presumed safe’ activity. Perhaps one of many.

I’ll leave it as an exercise to the reader to prove that there is no way for malware to futz with the ‘safe copy’ of the BIOS that could overwrite the other. (Hint: as if)

depends how it is implemented

if the button is an actual hardware reset that forces a reload from ROM that seems like it would work

if it is just a software call then the malware would just reset your settings and lie to you, and if it is not an actual ROM it would just write itself in the backup...

For better computers, the BIOS updates are usually signed with a key that is compared to the author list. Tougher to screw with by far.

https://www.coindesk.com/sec-rejects-latest-bitcoin-etf-bid


Think that the dissent by SEC Commissioner Hester Peirce is quite telling how much Bitcoin getting traction / being adopted is being feared:

Quote
"This line of disapprovals leads me to conclude that this Commission is unwilling to approve the listing of any product that would provide access to the market for bitcoin and that no filing will meet the ever-shifting standards that this Commission insists on applying to bitcoin-related products—and only to bitcoin-related products"

the problem of politicians is that even when there is a serious situation they continue to lie, I do not believe in the numbers that the Chinese government keeps talking. the situation is probably much more serious and china continues to lie about the numbers of dead and infected

Newer BIOSes.
I forgot to mention, i'd never use such for plugging in untrusted usb media.
My good old Pentium-M notebook is still running, as long as mains power is supplied.
12 year old NAS with usb should also do, wouldn't even accept input devices.
Totally wrong?

if it is just a software call then the malware would just reset your settings and lie to you, and if it is not an actual ROM it would just write itself in the backup...

Imo, it depends if the reset procedure copies over a default BIOS from actual ROM (safer, resets to factory BIOS) or a copy of the current BIOS from NVRAM (not safe at all).
I'd suggest it's the latter. I have a P7 milspec grade board made by asus, dual bios, read from NVRAM. So i wouldn't consider anything like this as safe as long as proven otherwise (security standard certification).

The less (free) information from china (and similar dictatorships), the worse the situation, imo.

Sigh! looks like we're going lower again the order books are evenly distributed again. Sellers are definitely chasing the price down.

No worries though, they will run out of coins soon and the further down it goes the more BTC I can get with my fiat. Halvening on the 12th of May, less coins for the sellers and less for us buyers.

Virgin Galactic CEO: Everyone Should Have 1% of their Assets in Bitcoin

Chamath Palihapitiya, the billionaire chairman of spaceflight company Virgin Galactic, has recommended that everyone hold Bitcoin (BTC) as a form of crisis insurance.

Speaking on CNBC’s Squawk Box, Palihapitiya said he believes that “everybody should probably have 1% of their assets in Bitcoin.”

Palihapitiya said that Bitcoin comprises a “fantastic hedge,” as every other financial instrument is correlated [...] except Bitcoin, which is fundamentally uncorrelated.”

"When you see the amount of leverage the financial industry is running, and you think about all these dislocations and all these exogenous things that are happening that you can't predict, there's a lot of risk to the downside, and it will be great that an average individual citizen, of any country in the world, has an uncorrelated hedge.”

Bit late to share this piece (3days) considering how quickly things change here in bitcoinlandia but fits every time when downtrend continues.
When HODLING Bitcoin, There’s Only One Number That Really Matters - Hint: this number is not the price of Bitcoin.

Quote
You Have to Think Long-Term With Bitcoin
I often say that the best strategy with Bitcoin is the simplest. It consists of 3 steps:
1. Buy Bitcoin
2. HODL Bitcoin
3. Repeat from Step 1
This model requires a true confidence in Bitcoin, and the revolution it builds block by block.

Here is the Head of Homeland Security testifying in front of Congress that the Coronavirus has a mortality rate of about 2%(likely in the ballpark) and that the normal Flu has also had a mortality rate of 2% over the last decade. Anyone who has spent more than 5 minutes online in the last few weeks knows the Flu mortality is a small fraction of a percent(.1), not 2 percent. Only about 2000% inaccurate.  Roll Eyes

This wasnt a Biden gaffe. The Senator asks if he is sure, he replies he is sure. LMFAO  Grin

This just shows the masses the incredible incompetence and ignorance of the Govy boyz.

https://twitter.com/nowthisnews/status/1232916522948935680


Money is about, among other things, trust and belief. When the Aids Flu is done slaughtering older nocoiners across the globe, trust in governments will be at never before seen lows.

This is Uber Bullish for King Bitcoin as they will put their trust in him, and the world will be a better place for it.

Warren Buffet, the King of all Nocoiners, is 89 and lives off of Mcdonalds, Cherry Coke, and candy. When he catches Aids Flu Id give him a 50/50 shot of surviving if infected.

https://www.businessinsider.com/warren-buffett-diet-2017-10

Buffet's partner Charlie Munger is 96, I give him a 2 percent chance of surviving if he catches it.

The future is going to have a lot less old men and women yelling at Bitcoin.

No one is happy that so many elderly may die, but lets be real about the economics of it. They are almost all nocoiners and they will leave their assets to the younger generation, many of whom cant wait to go balls deep in the King. No homo.
