1  Local / Português (Portuguese) / Re: Com ajuda de hacker, afortunado recupera acesso a uma wallet BTC contendo 15M R$ on: June 01, 2024, 05:27:57 PM
Como a password foi gerada por esse programa, que tinha essa falha (não sei se ainda tem, mas eu não usaria esse programa), permitiu eles poderem gerar milhares de passwords, até aparecer a password certa.
A falha foi corrigida pela RoboForm algures em 2015. Posso estar errado na versão exacta, mas diria que foi a partir do patch 7.9.14[1] a aleatoriedade da senha foi melhorada:
Quote
* Chrome: speed up message processing, when there is a lot of tabs.
* Chrome: avoid message queue overflow when user has a lot of tabs and windows.
* Chrome: fix RF toolbar for Chrome Basic Auth is shown at wrong position on high DPI.
* Chrome: do not ever modify Chrome settings, not even to remove old RF extensions.
* Chrome: make RoboForm extension for RoboForm Full (not Lite) visible in Chrome Web Store.
* Password Generator: increase randomness of generated passwords.

Two more suggestions that you may find use for:

Disclaimer: You should never share your seed words with anyone, especially one that contains the address that you attached to your profile (Ninjastic.space seems down so I'm unable to see if it is your staked address or not, but if that is the case then it is even worse as someone could reset your password).

Have you tried making again the transaction in your wallet? I can't seem to find it on mempool.space nor blockchair, so at first I would say that your transaction wasn't sent to the network in order to be picked up by the miners.

I advise you to follow a guide[1] that covers the full installation of mempool.space correctly. As far as  know you need both a Bitcoin Core + Electrum Server in order to fully benefit from mempool.space capabilities.

I use the travel agency cheapair.com for plane tickets and hotel rooms because you can pay with bitcoins.

I used to buy gold with bitcoins at apmex.com but they use Bitpay, which now has a really annoying KYC process.

More good suggestions. Thanks again.  I'll check these out and then add them to the top of the thread.
Disclaimer - BitPay doesn't have a good history of being privacy friendly (in fact it ends up being quite the opposite[1]). If you surprass this, then I you can use this[2] directory that lists businesses that run BitPay payment gateway and if you choose the option "Pay Direct" you'll supposedly get a list of businesses that accept bitcoin (amongst others).

Pardon me but why is AMC on this list? I can only find gift cards on their website and those can be purchased officially using Google pay or credit/debit and Paypal.
(...)
When I suggested AMC Theaters I simulated that I was purchasing some tickets and in the final checkout page - where you select the payment type - you were able to select BitPay as a payment option. I assumed Danny wasn't looking for the options of "buy gift cards with bitcoin", hence why I only suggested businesses that you can spend bitcoin directly. Perhaps you checked AMC (streaming platform) and not AMC Theaters)?

@Danny: Besides using BitPay directory[2] you can also use BTCPay directory[3] to see more services that accept bitcoin. I prefer to use this payment gateway because it is far more privacy oriented than BitPay (can be self-hosted and is open sourced).

1. Supposedly, Bitcoin can be used at menufy.com for SOME restaurants. Does anybody know how I can get a list of which menufy restaurants I can pay with Bitcoin?
I've given a quick look and it seems that you aren't able to filter locations by payment type. I wasn't expecting this considering that the business is running for quite some time and I am sure that these kind of filtering options - payment type supported - are something that has to be sought by their clients. Even though they state that their customers can accept multiple cryptocurrencies[1] you are left in the void as to how to do that (BitPay is the payment gateway[2]). I guess that you just have to be lucky in having a restaurant that you intend to buy and (hopefully) it accepts bitcoin as a payment.
2. I've tried looking at coinmap.org to find somewhere local that I can spend Bitcoin, but the results there seem very outdated.  Most of the places I've found on there no longer seem to accept Bitcoin. Can you recommend any websites or apps you find most reliable for finding local brick-and-mortar places to spend Bitcoin?
One website that I see pop up every now and then is btcmap[3] which is community driven - and open source - listing a lot of services that - supposedly - accept bitcoin as a payment. Since this is a community effort some places may not have been recently updated but is better than nothing. You can filter by "Others" (which may include brick-and-mortar stores) and "Restaurants" to see if there is something of use near your location.
3. It seems that some of the best places to spend Bitcoin in the past (Expedia, Overstock, etc) are no longer accepting Bitcoin.  What are some of the most mainstream product and service providers in the U.S. that accept Bitcoin payments right now?
Well mainstream is a pretty encompassing word, and perhaps I'm starting with a bad one, but I do know that you can use bitcoin in AMC Theatres[4], Newegg[5] and Chipotle[6]. I tested all of these - minus Chipotle - and they offer bitcoin as a payment (mostly using BitPay) in the checkout page.

I think you have two options that you can try:
  • Run your local instance of mempool.space (by using Docker[1] for example) + Local Node. I would highly recommend doing this considering the amount of freedom and privacy that you'll get;
  • mempool.space doesn't seem to have a capability to filter UTXO's. You either look for another blockexplorer API or perhaps you can try to add more arguments to jq. Considering the documentation[2] you could try filtering the results? For example, if you use [0:15] as an additional argument, it supposedly only prints the first 15 UTXO's. It should be something like this:
Code:
curl -sSL "https://mempool.space/api/address/AddressGoesHere/utxo" | jq '.[0:15]' > data.json

    hello i would want to buy bitcoin from what people told me its possible to get scammed here so if someone want to sell me bitcoin in spain in Alicante it would be very nice... or is it do able to do a safe transaction here without doing kyc? my amount to buy for is around 800€-1000€
    The chances of being scammed drastically reduce if you buy from reputable sellers/users that may be willing to sell you bitcoin. As always, do not reply to shady PM's and, when in doubt, always use a trusted escrow.

    Now, regarding your intention to buy non-kyc bitcoin, have you tried/heard of Peach Bitcoin[1]? I often recommend it to new users that are looking to buy bitcoin mainly because it is so easy to use and to quickly setup your accounts.

    You just have to install their application on your mobile device and then you will be be able to see offers to sell bitcoin at different amounts. You just choose the offer that matches your requirements and in a couple of minutes you'll have bitcoin directly sent either to your peach wallet or an external address controlled by you.

    If you have any doubts or further questions about it you can post them in the official thread[2].

    However, my recollection is that by having UPnP enabled ends up being a security risk considering that you are basically allowing anything within your device to open ports directly into your firewall. If you end up having malware on it, then it can quickly spread to the remaining (vulnerable) devices in the network.
    Unfortunately, I didn't pay enough attention to its consequences when I was running a node in the past [SMH] until I read your comment and did some Googling... It appears that you're right [it looks like I'll be sticking with outbound connections whenever I decide to run a node again (thank you)].
    - For those who might be interested, here are two old threads (#1 and #2) with interesting arguments about it.
    Glad that I could help. UPnP and DMZ are one of those things that shouldn't ever be touched considering the security holes that they end up creating in a user network.

    I have to say that I had never heard of having to pay a premium for port forwarding capabilities, but I reckon that nowadays ISPs are always looking for ways to charge customers functions that should be made available freely.

    In case some guidance is needed for whoever is reading this, I always share this[1] website for people looking to port forward - it has a large array of suppliers and it covers the needed steps for someone to successfully port forward (assuming the ISP isn't greedy...).

    I can't get an output formatted like that. When I do the call: curl -sSL "https://mempool.space/api/address/1KFHE7w8BhaENAswwryaoccDb6qcT6DbYY/utxo" > data.json
    What if you try the following code:
    Code:
    curl -sSL "https://mempool.space/api/address/1KFHE7w8BhaENAswwryaoccDb6qcT6DbYY/utxo" | jq '.' > data.json
    All I did was adding | jq '.' to your initial input. jq is a JSON processing tool[1] - and since API usually return JSON data when called - it should get the job done by formatting the data before saving it to your named file (in this case data.json).

    If port forwarding is a premium service on OP's side, then this is a clever workaround for it. However, my recollection is that by having UPnP enabled ends up being a security risk considering that you are basically allowing anything within your device to open ports directly into your firewall. If you end up having malware on it, then it can quickly spread to the remaining (vulnerable) devices in the network.

    Note that I haven't messed around with UPnP for ages, perhaps the protocol developed more since last time I tinkered with it...
    12  Other / Meta / Re: A concise 2FA/TOTP implementation (SMF patch) on: May 21, 2024, 08:03:30 AM
    Hey Rick. Sorry for taking so long to get back to you. I get what you're referring to, but, I don't know... I don't think recovery codes make that much sense for this implementation (in terms of value added vs. complexity added). There's already a worked-out mechanism for recovering access to your account if you lose your 2FA app/device (just do an e-mail based password reset and check the appropriate box). I guess, if people would really rather avoid doing a password reset, then, what they could do (though I don't recommend it, not unless they really know what they're doing) is keep a copy of their Base32-encoded secret somewhere, and then, if the need arises, they could either import that into something that easily accepts Base32 secrets, like KeePassXC, or they could paste/place it into the above script and (either way) then generate the OTPs necessary to get back into their account and disable 2FA (before presumably re-enabling it with a different/fresh shared secret).
    Thank you for your concise reply. I totally understand your perspective, especially considering the fact that there is already a backup solution - in means of e-mail password reset - and that it would complicate the code further. In my mind I had the expectations that perhaps it would just be a case of inserting an already existing slice of code into the main body of SMFs code to generate those recovery codes associated with the secret. Considering that it isn't the case, and the fact that you make these improvements on your own free time, it doesn't justify the trouble...

    In addition to nc50lc reply, you can also try using the API provided by mempool.space[1] to access that information:
    Code:
    curl -sSL "https://mempool.space/api/address/1KFHE7w8BhaENAswwryaoccDb6qcT6DbYY/utxo"
    Returns:
    Code:
    [
      {
        txid: "12f96289f8f9cd51ccfe390879a46d7eeb0435d9e0af9297776e6bdf249414ff",
        vout: 0,
        status: {
          confirmed: true,
          block_height: 698642,
          block_hash: "00000000000000000007839f42e0e86fd53c797b64b7135fcad385158c9cafb8",
          block_time: 1630561459
        },
        value: 644951084
      },
      ...
    ]
    mempool.space doesn't publish what are their API limits so once you start getting HTTP 429 error you will know that you've reached them. If you intend to make several calls perhaps it would be wise to balance them between some blockexplorers' APIs to avoid being blocked/rejected by their APIs.

    Mempool.space is somewhat new and rapidly became the best and one of the explorers with higher traffic out there, much better than blockchain.com and other competitors. That certainly is worth money  and sponsors know that.

    I am happy to see they are making money with enterprise packages and the accelerator. They offer a good service and they are always making improvements in the ui.

    They certainly have high development costs and server costs. They need money inflow to keep up the good work
    Indeed they are newish - they first appear around 2019[1] - and they have been growing in size (infrastructure and users) ever since. Bitcoin Magazine made a interview with the two lead maintainers in 2020[2] that I advise anyone to read if there is any interest in knowing the roots of mempool.space. I really liked this reply[3] from Simon regarding one of mempool.space mission:
    Quote
    But compared to many other Block Explorers  we are at least Open source, we self host and own our server hardware, no Amazon or Google surveillance. You CAN access the website over TOR. You CAN one-click install the whole solution on your Raspberry Pi device and be sovereign.
    As long as the core Bitcoin community likes what we are doing, it will be a force that continue to help spreading the word of how to run Bitcoin infrastructure properly.

    Assuming the Beelink is the same one that Amazon is selling here in the US after getting the 1TB drive you now have the old 512GB that you can sell dropping the price even more.
    The one I saw was from a random vendor in Amazon Germany[1] and it came with a 500 GB PCIe M.2 SSD which hovers around 40-50 €. If you're able to sell it you'll be able to have the unit ready with a 1TB for overall 210-230 € depending on the SSD you get.
    Still, the H4 is a neat product, will probably pick one up if the price drops since it's going to probably get played with and tested and put in a cabinet and forgotten about......
    So it is not only my disease it seems, good to know. If the price does drop I would also consider fetching a unit, but right now the price difference is big when compared to other (similar) options available.

    Advertising isn't being implemented on their website (you can check out why here[1]). mempool.space does offer Enterprise packages that offer more options for advanced partners[2] so that is one source of revenue (in addition to the newer one that comes from their paid accelerator) and they also have the option for users to sponsor the project as well[3]. Do note that the project isn't made by a company so profitability isn't their main mission:
    Quote
    It is an open-source project developed and operated for the benefit of the Bitcoin community, with a focus on the emerging transaction fee market that is evolving Bitcoin into a multi-layer ecosystem.
    They are, however, a great group of people that are working towards a project - perhaps some of them in their free time - that is free to use and if people find it useful then they are able to contribute in some way.

    That's great then. I'm sorry for the inbound connections but i'll help with the outbound then.

    Thank you for the clarification.
    Do note LoyceV reply before mine as I think that it's an interesting path to explore if you're willing to. I recommend the second approach (VPS with OpenVPN) and you can follow this[1] guide in order to have it up and running.

    How about a VPN with port forwarding (or a cheap VPS with OpenVPN installed)?
    Most well regarded VPN providers - such as Mullvad or IVPN - have removed the ability to do port forwarding. Proton still allows it[1] but you have to be a paid subscriber and you also get the port chosen by the program and you have to change it each time you restart the VPN connection. Considering that I personally do not trust other VPN providers, my recommendation would be the second option (VPS with OpenVPN installed).

    Reviews of Odroid H4 are starting to appear[1] (H4 Plus vs H4 Ultra). It seems that the Ultra reaches high temperatures (around 60ºC) and since it doesn't have holes to mount a fan, but this could be surpassed by mounting the fan in the case (although it is not optimal). The section where he played an emulated game in there (God of War 2) wasn't that great as well, but that could had to do with some configurations.

    H4 Plus ended up being the chosen winner for his review (considering that is cheaper, low powered consumption, less heat), so it's a case that the pricier may not be the best overall.

    Price wise, the H4 Plus in Europe is hovering around 180 €[2] and this is just the board. Considering charger, memory (16GB) and SSD (1TB) it goes up to ~ 380 € and it would still need a case. The Beelink Mini S12 Pro can be found for 200 € in Europe right now + a 1TB nvme stick for around ~ 60 €, so the price difference ends up being more than 120 € considering that we are missing a case. As it stands currently, it ends up being a better alternative (price wise) between the two.

    Great to see this year edition of the bitcoin pizza day is happening directly on the forum, perhaps it will achieve more users this way, congratulations! Really looking forward to see what the community is able to cook for this year edition.

    I think that is should be quite easy to understand what can considered as pizza and what is simply not acceptable. Last year we saw some entries that were not pizza, some them were not even cooked. As long as you have a cooked dough you should be fine.
    We are all adults, if you go to a restaurant and ask for a pizza I'm pretty sure you don't expect to receive a cold plate with some random ingredients, don't you?
    In different countries, on plates you will see completely different pastries disguised as pizza (to the horror of the Italians). Smiley Therefore, specifically stated conditions are the key to the transparency of the competition.
    This also happened a lot in both edition of the Pie baking contest that I organized. I reckon that one dessert, in this case, may have different meanings in certain parts of the world, but even though users were warned in the second edition of what kind of pies we were looking for, some still submitted their own interpretation of it (which didn't got into the final voting phase).

    In this particular case the rules are straightforward. If users are still unsure what kind of entry is being considered, what better way to get their doubts clarified than looking at the original pictures[1] that inspired the contest?  Wink

    Where did I write that this is a virus? I clearly wrote that the files belong to the system, most likely Windows, and there is no point in wasting time looking for something that is not there.
    The OP remembers buying Bitcoin, so he associates all the words “crypto” with his desire to find Bitcoin many years from now.
    But unfortunately, most likely, this will remain only in dreams.
    My bad, I misinterpreted your post, I'll edit it. The remaining of what you said still holds up, especially considering that most people will get their hopes up with anything that says "crypto" in their filenames. In this particular case it seems that OP had his hopes settled rather quickly.
