1021  Bitcoin / Electrum / Re: I think I lost all my BTC with electrum on: December 27, 2018, 06:27:00 PM
Can some expert here let us newbies know how something like this could have been avoided? Would it be to do a PGP check on every electrum download we make? Is that sufficient to prevent this from happening?

 - Electrum is a low-security wallet in general. It focuses on bleeding-edge features and usability, not absolute security. Store only pocket change there (and on the same computer as Electrum). For storing large amounts, use a hardware wallet.
 - The fact that this phishing message was prefixed by "error: error sending transaction" should make one immediately suspicious. If you feel any suspicion about anything, stop and discuss it on the forum or elsewhere.
 - When a new update comes out, wait a week or two before installing it. If it's listed as critical, look at various sites such as bitcointalk.org to figure out why it's critical. If in doubt about whether a "critical" update is real, you can just stop using Electrum for a few days and wait for further news.
 - Navigate to the site using a bookmark if possible, and use HTTPS.
 - Verify the PGP signature when you download it.
 - When you run the executable on platforms that support digital signing, make sure that it's signed by "Electrum Technologies GmbH"
1022  Bitcoin / Important Announcements / Electrum vulnerability allows arbitrary messages, phishing on: December 27, 2018, 01:17:14 PM
If you're using Electrum or a derivative, you may receive a message like this:


This message is false, sent to you by a hacker. If you click the link in the message and install the software, then your BTC will be stolen. If you ignore the message, then you should be OK. Version 3.3.2, released a week ago, makes the messages less readable/convincing, though you could still receive such messages.

Note that altcoin derivatives of Electrum are very common, with over 1600 forks on github, and they will also be affected.

I was trying to translate the OP (https://bitcointalk.org/index.php?topic=5089777.0) for my local board, since it's an important topic for all to see, but I'm having issues when trying to include the recovery email in a forum post:

Rather than copying the email address, please just say "the email address in theymos's post" or similar. These email addresses will be periodically cycled, so if you copy it, it'll stop working eventually.

Thanks.
1024  Other / Meta / Re: Account recoveries are moving again on: December 26, 2018, 05:56:36 PM
You know that there are many appeal-threads where users already provided their signed message. The hacker will simply create a new email and copy paste the signed message.

That's why signed messages for account recoveries have to include the desired new email and a date.
1025  Other / Meta / Re: Account recoveries are moving again on: December 26, 2018, 05:28:25 PM
A bit off topic (not sure): How about the script you were writing we heard from the PM of one of the member (qwk i guess)?

Not sure what you're referring to. One thing I'm working on (maybe for release in the first half of 2019, not sure) is a proper address-staking system. The main point of this would be to replace the current ad hoc address staking situation and safely allow opting out of any of: long-term IP log retention; email password recoveries; or manual recoveries. Automatic recoveries using a staked address is possible, but not much on my mind right now.

I have something in my mind and I want to be reassured:
If the owner of a locked account send an appeal from a new email, will you unlock his account?

edit: the user provides a signed message.

If a signature is provided, probably. But each case needs to be considered separately.
1026  Other / Meta / Account recoveries are moving again on: December 26, 2018, 04:01:40 PM
We've streamlined our processes, and Cyrus has put together a team for handling these cases, so account recoveries should now be handled at a reasonable pace again. Additionally, we will be somewhat more lenient in recovering accounts without signatures, though signatures often will still be required, depending on the situation.

If you have a locked account, send a new email to the @bitcointalk.org email address given in your "account locked" error message. (The email address changed a few weeks ago.) If you were previously sending messages to me or Cyrus, send a new email to the address here. We might try to go through the backlog of old-process recoveries in the future, but for now you should send new messages.

Sorry for the delay!
1027  Other / Meta / Recovering hacked/lost accounts on: December 26, 2018, 03:48:07 PM
If you get a message similar to "your account is locked"

You should be given an email address in the error message. Send an email there and you will be given further instructions.

If you are banned

Your ban message may have an email address which you can email. If not, then appeals are unlikely to be accepted.

If your account was hacked

Email recoveries_2021_xxlgg@bitcointalk.org, ideally from the account's email address. Include your username and a brief description of the details of how/when the account was hacked. A signature will likely be required (see below).

If you forgot the password or similar

Try using the email password reset. Check that the email isn't ending up in your spam folder. If that doesn't work, email recoveries_2021_xxlgg@bitcointalk.org, ideally from the account's email address. Include your username. A signature will likely be required (see below).

Signatures

Often, you need to prove ownership of the account with a PGP or Bitcoin signature. This has two steps:

 1. You need to show that the PGP key or Bitcoin address is associated with the account, for example by referencing an unedited post in which you posted the address.
 2. You need to sign an appropriate message with that key/address.

For example, this is an example of an appropriate proof of ownership:

Quote
-----BEGIN BITCOIN SIGNED MESSAGE-----
My account <account> has been hacked/lost. Please reset the email to <email>. The current date is <date>.
-----BEGIN SIGNATURE-----
<insert address here>
<insert signature here>
-----END BITCOIN SIGNED MESSAGE-----

Here is the unedited post where I posted that address: ...

Note the following elements:
 - The message contains the username, the desired new email, and the current date.
 - You specify the address.
 - You include a signature.
 - You link to the association between the address used for signing and the account.
1028  Other / Politics & Society / Common ground on: December 24, 2018, 09:15:36 PM
In the spirit of Christmas, can we on bitcointalk.org try to find some political consensus? Can Flying Hellfish and TECSHARE agree on anything?

Some points which might find general agreement:
 - The freedom of individuals is important.
 - The prevailing banking/fiat system is on the whole bad.
 - In most places, the people would be far better off if major changes were made to their respective governments.
 - As long as scarcity exists, the existence of some form of trade is good.
 - Technology is good.
 - Humanity should dominate the universe.

Any others? Do you disagree with even those broad statements?

1030  Other / Politics & Society / Re: Mad Dog Mattis Resigns - Trumps replacement? on: December 21, 2018, 05:30:49 PM
I actually hadn't read Mattis as a huge neocon, but his resignation letter indicates that he must've at least largely bought into the neocon argument. I suppose the whole Pentagon culture which he has been immersed in has been very pro-intervention.

I'm surprised and very happy with Trump's actions here. In addition to the Syria withdrawal, it wasn't widely reported that Trump simultaneously also ordered withdrawing half of the troops in Afghanistan. It seems that he's finally starting to go with his instincts even in opposition to his neocon advisors. While his instincts are far from ideal, they're a hell of a lot better than eg. "bomb-everyone Bolton". I'm a little doubtful that Trump will keep up this policy with any consistency, but if he does follow a consistent anti-intervention path from here on out, I will probably end up considering him the best president in many decades even despite his many other flaws.

So far, Trump has always picked establishment, neocon cabinet members. If he picks an anti-war Secretary of Defense, that might indicate a true shift.

Pick any point on the map at random and you will find horrible injustice. The US can't intervene everywhere, and history has proven that it usually causes more evil in intervening than it sought to prevent. For example, in trying to fight the admittedly-evil regime in Iran and "stabilize the region", the US is propping up the even more evil regime in Saudi Arabia, which is itself perpetuating what is essentially a genocide in Yemen. It's better to just get out of there completely. These wars are also all unconstitutional.

I wish the Kurds the best, especially given that Bitcoin's own Amir Taaki was fighting in their ranks for some years, but it's not the US's war to fight.
1031  Economy / Auctions / Re: Advertise on this forum - Round 264 on: December 20, 2018, 03:52:00 PM
Note that I have added a new rule:

Quote
Price flattening

At the end of the auction, after the winning bids are all determined, I will do a "price flattening" operation. This has no effect on which bids actually win. For each bid, in order of lowest to greatest price/slot, I will reduce each bid's price/slot to the highest value which is equal to or only the minimum increment greater than the next-lower bid. This allows you to bid higher prices without worrying so much, but you still mustn't bid more than you're willing to pay. Example:

Code:
This:
Slots  BTC/Slot  Person
    6      0.20       A
    1      0.16       B
    1      0.08       C
    1      0.08       D

Becomes:
Slots  BTC/Slot  Person
    6      0.12       A [step 4: reduced to 0.10+0.02=0.12]
    1      0.10       B [step 3: reduced to 0.08+0.02=0.10]
    1      0.08       C [step 2: same as the next-lowest, unchanged]
    1      0.08       D [step 1: the lowest bid is always unchanged]
1032  Economy / Auctions / Advertise on this forum - Round 264 on: December 20, 2018, 03:51:40 PM
The forum sells ad space in the area beneath the first post of every topic page. This income is used primarily to cover hosting costs and to pay moderators for their work (there are many moderators, so each moderator gets only a small amount -- moderators should be seen as volunteers, not employees). Any leftover amount is typically either saved for future expenses or otherwise reinvested into the forum or the ecosystem.

Ads are allowed to contain any non-annoying HTML/CSS style. No images, JavaScript, or animation. Ads must appear 3 or fewer lines tall in my browser (Firefox, 900px wide). Ad text may not contain lies, misrepresentation, or inappropriate language. Ads may not link directly to any NSFW page. No ICOs[1], banks, funds, or anything else that a person can be said to "invest" in; I may very rarely make exceptions if you convince me that you are ultra legit, but don't count on it. Ads may be rejected for other reasons, and I may remove ads even after they are accepted.

There are 10 total ad slots which are randomly rotated. So one ad slot has a one in ten chance of appearing. Nine of the slots are for sale here. Ads appear only on topic pages with more than one post, and only for people using the default theme.

Duration

- Your ads are guaranteed to be up for at least 7 days.
- I usually try to keep ads up for no more than 8 or 9 days.
- Sometimes ads might be up for longer, but hopefully no longer than 12 days. Even if past rounds sometimes lasted for long periods of time, you should not rely on this for your ads.

Stats

Exact historical impression counts per slot:
https://bitcointalk.org/adrotate.php?adstats

Info about the current ad slots:
https://bitcointalk.org/adrotate.php?adinfo

Ad blocking

Hero/Legendary members, Donators, VIPs, and moderators have the ability to disable ads. I don't expect many people to use this option. These people don't increase the impression stats for your ads.

I try to bypass Adblock Plus filters as much as possible, though this is not guaranteed. It is difficult or impossible for ABP filters to block the ad space itself without blocking posts. However, filters can match against the URLs in your links, your CSS classes and style attributes, and the HTML structure of your ads.

To prevent matches against URLs: I have some JavaScript which fixes links blocked by ABP. You must tell me if you want this for your ads. When someone with ABP and JavaScript enabled views your ads, your links are changed to a special randomized bitcointalk.org URL which redirects to your site when visited. People without ABP are unaffected, even if they don't have JavaScript enabled. The downsides are:
- ABP users will see the redirection link when they hover over the link, even if they disable ABP for the forum.
- Getting referral stats might become even more difficult.
- Some users might get a warning when redirecting from https to http.

To prevent matching on CSS classes/styles: Don't use inline CSS. I can give your ad a CSS class that is randomized on each pageload, but you must request this.

To prevent matching against your HTML structure: Use only one <a> and no other tags if possible. If your ads get blocked because of matching done on something inside of your ad, you are responsible for noticing this and giving me new ad HTML.

Designing ads

Make sure that your ads look good when you download and edit this test page:
https://bitcointalk.org/ad_test.html
Also read the comments in that file.

Images are not allowed no matter how they are created (CSS, SVG, or data URI). Occasionally I will make an exception for small logos and such, but you must get pre-approval from me first.

The maximum size of any one ad is 51200 bytes.

I will send you more detailed styling rules if you win slots in this auction (or upon request).

Auction rules

You must be at least a Jr Member to bid. If you are not a Jr Member and you really want to bid, you should PM me first. Tell me in the PM what you're going to advertise. You might be required to pay some amount in advance. Everyone else: Please quickly PM newbies who try to bid here to warn them against impersonation scammers.

If you have never purchased forum ad space before, and it is not blatantly obvious what you're going to advertise, say what you're going to advertise in your first bid, or tell me in a PM.

Post your bids in this thread. Prices must be stated in BTC per slot. You must state the maximum number of slots you want. When the auction ends, the highest bidders will have their slots filled until all nine slots are filled.

So if someone bids for 9 slots @ 5 BTC and this is the highest bid, then he'll get all 9 slots. If the two highest bids are 9 slots @ 4 BTC and 1 slot @ 5 BTC, then the first person will get 8 slots and the second person will get 1 slot.

The notation "2 @ 5" means 2 slots for 5 BTC each. Not 2 slots for 5 BTC total.

- When you post a bid, the bids in your previous posts are considered to be automatically canceled. You can put multiple bids in one post, however.
- All bid prices must be evenly divisible by 0.02.
- The bidding starts at 0.02.
- I will end the auction at an arbitrary time. Unless I say otherwise, I typically try to end auctions within a few days of 10 days from the time of this post, but unexpected circumstances may sometimes force me to end the auction anytime between 4 and 22 days from the start. I have a small bias toward ending auctions on Fridays, Sundays, and Mondays.
- If two people bid at the same price, the person who bid first will have his slots filled first.
- Bids are considered invalid and will be ignored if they do not specify both a price and a max quantity, or if they could not possibly win any slots

If these rules are confusing, look at some of the past forum ad auctions to see how it's done.

I reserve the right to reject bids, even days after the bid is made.

Price flattening

At the end of the auction, after the winning bids are all determined, I will do a "price flattening" operation. This has no effect on which bids actually win. For each bid, in order of lowest to greatest price/slot, I will reduce each bid's price/slot to the highest value which is equal to or only the minimum increment greater than the next-lower bid. This allows you to bid higher prices without worrying so much, but you still mustn't bid more than you're willing to pay. Example:

Code:
This:
Slots  BTC/Slot  Person
    6      0.20       A
    1      0.16       B
    1      0.08       C
    1      0.08       D

Becomes:
Slots  BTC/Slot  Person
    6      0.12       A [step 4: reduced to 0.10+0.02=0.12]
    1      0.10       B [step 3: reduced to 0.08+0.02=0.10]
    1      0.08       C [step 2: same as the next-lowest, unchanged]
    1      0.08       D [step 1: the lowest bid is always unchanged]

Payment, etc.

You must pay for your slots within 24 hours of receiving the payment address. Otherwise your slots may be sold to someone else, and I might even give you a negative trust rating. I will send you the payment information via forum PM from this account ("theymos", user ID 35) after announcing the auction results in this thread. You might receive false payment information from scammers pretending to be me. They might even have somewhat similar usernames. Be careful.

[1]: For the purposes of forum ads, an ICO is any token, altcoin, or other altcoin-like thing which meets any of the following criteria: it is primarily run/backed by a company; it is substantially, fundamentally centralized in either operation or coin distribution; or it is not yet possible for two unprivileged users of the system to send coins directly to each other in a P2P way. The intention here is to allow community efforts to advertise things like Litecoin, but not to allow ICO funding, even when the ICO is disguised in various ways.
1033  Economy / Auctions / Re: Advertise on this forum - Round 263 on: December 20, 2018, 03:42:04 PM
9 @ 0.14

You have your own token, and you currently have no product, so I classify your site as an ICO.

1 @ 0.1

Rejected, see your PMs.

1034  Other / Politics & Society / Re: Brexit status on: December 17, 2018, 10:49:22 PM
I don't believe in politics as an effective way of doing anything. Look at Nigel Farage: he seems like a nice enough guy, and I more-or-less agree with his position, but he spent decades getting a brexit vote, and in the end it might all be for nothing. That's decades of time, effort, and pay down the drain. Even if he gets his desired no-deal-brexit, was all of that work really worth it to him and the people who funded him? I tend to think that the world would've been better off if he'd stayed a commodities trader and the UKIP donors used their money for something more fun/useful. (But people can choose what to do with themselves, of course.) And Farage is just an easy-to-understand example: I believe that nearly all political action is similarly a waste of resources, with each rare success being bought at a far higher price than it's worth.

I recommend against political donations, political volunteering, protests & similar political action, and I don't particularly encourage voting. That's all a waste of time. Instead, people should try to work around / in-spite-of politics. Wherever possible, don't put yourself in positions where you have to ask permission, even on small and/or non-governmental scales. Satoshi's creation of Bitcoin is a perfect example: in just a few years, Satoshi changed the world more than just about any politician, and he didn't have to compromise his principles whatsoever or ask permission from anyone. This is ideal.

So you'll probably never see me canvassing for any candidates or policies.

That said, I ironically very much enjoy following and discussing politics on a personal level, much like some people follow sports, and it can also pay to follow it because it can strongly affect eg. the prices of assets. If you look, you'll find that I do talk about US politics a fair bit. Brexit is especially interesting because it's unusual and unpredictable, unlike a lot of stuff in politics. IMO a no-deal brexit would at this point probably be the best result for the UK and the world, but again, I'm not recommending that anyone waste time on the matter.

will it unlock in 7 days?

No.

This is a component of a comprehensive new set of recovery procedures which will be fully rolled out in the very near future (before the end of the year). This will allow recoveries to move forward at a reasonable pace again. But there is no immediate impact of this component to most people; I just needed to document it because the seclog entries are starting to appear.

If you are given an email address on the page which tells you that your account is locked, then it may have recently changed. If so, sending an email to the new address may expedite things.
1037  Other / Meta / Re: FYI: "ownership change queued" on: December 14, 2018, 05:12:46 AM
Is it I understand correctly?

When someone want to change his email on BTT account,then he can't use his/her account for those 7 days because "The account stays locked throughout all of this.

No, the queue only applies when the administration changes the email address, not when you change it yourself. It's for recovering hacked accounts and similar. Most people don't need to care about it.
1038  Other / Meta / FYI: "ownership change queued" on: December 14, 2018, 04:41:28 AM
As an extra protection against any possible social engineering attacks, whenever* the administration changes an account's email address from its current value, the following process occurs:
 - The change is queued.
 - It is listed in seclog.php.
 - The old email receives a warning.
 - After 7 days, the change goes through and another seclog.php entry is added.

The account stays locked throughout all of this.

Hopefully it will be essentially unheard of, but if an account is going to be incorrectly transferred, everyone who knows about the incorrect change should noisily post all of the evidence they have so that we can at least put the change on hold and re-review the evidence.

* Admins can act outside of procedure and bypass the queue if necessary, but hardly ever will.
1039  Other / Politics & Society / Brexit status on: December 13, 2018, 06:12:01 PM
May's deal looks totally dead, but May herself seems relatively secure. It looks like nobody wants to take the blame when everything comes crashing down. I don't like her politics at all, and her deal was basically EU vassalage, but I kind of feel bad for May...

I think that no deal is likely to be reached, and they're going to cancel brexit at the last minute, either via a referendum or even unilaterally in parliament. Any future referendum will have a pro-EU result. Brexit's cancellation will absolutely infuriate the substantial minority of people who are still strongly pro-brexit. IMO the brexit people celebrated too soon, and haven't been doing enough to lock things up. Moreover, the whole UK political system has long been hopelessly screwed up, even moreso than the US, so it's difficult to expect any positive results in anything.

A no-deal brexit would probably be the best long-term result, especially if they can also bring themselves to significantly loosen their regulations vs the EU. The "A+ plan" would be very net-good for the UK long-term, for example, but it seems impossible; IMO the people of the UK would sooner accept May's vassalage deal with the EU than reduce their regulations so much. In any case, a hard brexit will probably cause a several-year-long economic depression in the UK as the economy adapts -- will the people freak out during this and demand returning to the EU (under extremely unfavorable terms)?

What are your predictions? If you're in the UK, how are things looking there?

This kind of algorithmic accident based on over-trusting the zeitgeist has existed pretty much since Google was first created. Remember "french military victories" being suggested to "french military defeats"? If you look for them, you'll find them.

But has anyone else noticed that Google Search has gotten really bad over the last few years? Oftentimes I search for something kind of obvious, half of the results on the front page are from the same site that I'm not interested in, and the things I'm looking for are either unfindable or many pages deep. I'd like to use DuckDuckGo, but it's really bad, only working (sometimes) for the most simple queries.
