Ledger App Isolation Bypass
04 August 2020

https://monokh.com/posts/ledger-app-isolation-bypass

This post will disclose a vulnerability in the Ledger hardware wallets that can lead to theft of user funds.

An attacker can exploit this method to transfer Bitcoin while the user is under the impression that a transaction of another, less valuable altcoin (e.g. Litecoin, Testnet Bitcoins, Bcash, etc.) is being executed

If you use bitcoin forks on your device, you could be affected. You should avoid using these ledger apps until fixes are available.

The issue has been disclosed to Ledger but remains unaddressed. See Disclosure Timeline.

I've always preferred my Trezor more than my Ledger; this just reinforces that belief

To upgrade the firmware on the Ledger you have to delete the "Bitcoin app" first. Very scary process. I don't like clicking a button that says "Do you want to delete your bitcoins? Are you really really sure??"

Somehow it remembers the pass phase so you don't have to reenter it, but still.....

They are wasting everyone's time putting shitcoin support on this thing, and (as now demonstrated) increasing the attack surface. Very stupid IMHO.

You're only deleting the "app" not the seed but yes, I agree. It's a very weird process

I have a gut feeling of 12500, this weekend.  

I hope so

FWIW, deleting the "Bitcoin app" should not scare you at all. If it does, then you either haven't understood how a wallet works, or you haven't followed the appropriate steps to secure it. A seed can't be deleted. As long as you have your seed securely backed up (ideally in multiple places, physically separate from each other), then you have no reason to be scared. Trezors/Ledgers are just fancy containers.

Reality check: if you feel worried and scared at the thought of your Trezor/Ledger being lost, stolen, destroyed, you're doing it wrong.

#Bitcoin is ready to rip to all time highs.

Is Bitcoin really going to be the best ever and is it going to happen? Although Bitcoin has a lot of potential is bitcoin just moving at its own pace or is bitcoin being influenced by something?

Bitcoin is being influenced by something, yes. It’s called the power of the people who no longer want to be controlled by their governments & slaves to inflationary currency. Bitcoin is the future young padawan. Buy before it’s too late.

What you are seeing with the price is the effect of the halving, reduce the supply, increase the demand which is the total opposite of what the Fed is doing, BRRRRRR !

If we're going to spend an entire August in 11xxx range... well, that's fine with me.

It's a good range!

Stability is good, sometimes trading in a sideways range for significant period is a good thing. Se were in the $9’000’s for a while before we broke out. I’m cool with being in the $11’000’s for a month or two if it means we break out & push towards $14,000 or something by November.

This is very important, bitcoin for the most part has gone above the 10k barrier but is has been unable to remain there for long, when looking at the historical data from coingecko this is what I get.

Days in a row above 10k.
From 28 NOV 2017 to 30 JAN 2018    63 days
From 01 FEB 2018 to 01 FEB 2018      1 day
From 16 FEB 2018 to 21 FEB 2018      6 days
From 23 FEB 2018 to 24 FEB 2018      2 days
From 27 FEB 2018 to 07 MAR 2018   9 days
From 22 JUN 2019 to 16 JUL 2019      25 days
From 19 JUL 2019 to 23 JUL 2019      5 days
From 01 AUG 2019 to 28 AUG 2019      28 days
From 03 SEP 2019 to 21 SEP 2019      19 days

From 02 JUN 2020 to 02 JUN 2020       1 day
From 28 JUL 2020 to TODAY       8 days and counting
Total: 173 days

Number of days above 10k by year

2017	33 days
2018	47 days
2019	78 days
2020	15 days and counting

2020 is the year where unpredictable things have happened which was not expected, or people have not seen in decades of their life. We are witnessing many things for 1st in our life and this year just could be the change for bitcoin as well and witness something which we had not seen till now.

Let's hope it is good for us and btc. I WANT 12345.67 SOON!

Ledger App Isolation Bypass

https://monokh.com/posts/ledger-app-isolation-bypass

Definitely worth mentioning, but not as dramatic as it seems at first glance -> https://bitcointalk.org/index.php?topic=5266620.msg54938150#msg54938150

I've always preferred my Trezor more than my Ledger; this just reinforces that belief

Trezor is of course one of the two choices when it comes to HW, but they also have their weaknesses that cannot be repaired at all - I hope you have set up passphrase on your device -> https://donjon.ledger.com/Unfixable-Key-Extraction-Attack-on-Trezor/

They say after 10,000 hours of something, you become a master of it. You guys are looking at a master of checking the #bitcoin  price.

https://twitter.com/bitcoincameron/status/1290700961447653385?s=21

I might be a master of a master in this one

Yes, El duderino_, for your assiduous services in difficult conditions to checking the #bitcoin price, the Board Of Giving Doctorates And Notices Of Virtuous Service has promoted you to the Honorarium Of Doctorates Licentiorum, and you may now assume the moniker El doctorino_ (HODL), or Dr duderino_ (HODL) if you prefer.

Dr duderino_ seems appropriate

Thx

Even though long, I kind of prefer mcdoctorduderino... for some strange reason... it seems to roll off the tongue better.

Might disincentivize updating... at least on the margins... which could add up to a decent number of people not updating to better security.

Can we speak for the average person?  or the average bitcoiner?  Even if you do not practice, you run out of skills and confidence, and humans are subject to making errors - even smart-ass peeps.

I have a gut feeling of 12500, this weekend.  

I hope so  

Chart from : https://twitter.com/inmortalcrypto/status/1290694835452678146

Found this on Twitter  

"11.5k is the most important level" ?

All right, I'll take it!

Now that we're well above it...

Now that we're well above it...  

14k, 17k, 19k, ATH or whatever else number being mentioned as "important" is not important at all in fact... we're just at the very beginning of this facemelting bullrun... I'd say the closest important level is around 25k as we'll move up into the "there be dragons" unmarked and unknown area...

I LOVE it when one of my random lines I drew last week is about to get punched.

I know I had some sort of rationale for this one...
