1  Alternate cryptocurrencies / Altcoin Discussion / Re: Someone sent ERC20 from my cold storage on: December 06, 2022, 09:20:52 PM
Nothing new to me. Iíve received such scam tokens deposited into my multiple wallets (even cold storage) and I just simply ignored them. But back then, I could have almost fallen victim but good thing I took time to research and doing my due diligence.

You just simply do not claim them nor touching it. Just leave it as it is and nothing happens.

This is the opposite. Token are moved FROM you wallet, not to your wallet. It's 0 tokens though.

It is a bug, not an exploit, for sure it shouldn't be an intended implication of the developer's intent. This also should not be on purpose. Allowing a transaction to be accepted without user consent seriously harms the ecosystem. In the first place, things like this should be considered if they are aware of the current flawed implementation occurrence. Thus it makes no sense if the smart contract developers were allowing this to happen.

Of course they knew, they were the ones who created this backdoor and vulnerability in the first place. Read the code, they made the code that accepts transactions without signature of the owner of the address. Without private keys. Other crypto like BTC or XRP don't have this backdoor.

The OP lacks details explaining the question. According to my analysis, the scenario is like this (correct if you have another opinion):

First, the attacker steals your address's private key. (This is how he gets your token.) This is impossible.

Second, the attacker creates a transaction that transfers all of your tokens to his own address, which is similar to yours. (The attacker has now taken your token without giving you anything in return.)

In the third, the attacker sends a transaction of 0 tokens from your address to his own address. (This is what makes it look like you sent the token to the scammer yourself.)

You have to read other posts in the thread. Your scenario is wrong. The explanation is a few posts above.

This scam is different because it makes it seem like the token transfer came out of your wallet. At first you think your seed is compromised however when you look closer it seems like its some exploit, which it is.

It is not exploit, it is a feature implemented by ETH devs, also copied to BSC. This was created on purpose, Ethereum virtual machine is coded to accept transactions from your wallet without private keys. Absolutely anyone can send any tokens from any wallet, as long it's 0.

And please explain to me why i can't find info on something even related to this or why no one is talking about this?

Because it's a new attack. And there are people discussing it, you just don't even bother to check.

Can you also sign messages with other people's wallets while you are at it?

I told you, only 0 token transaction is possible without your keys. Signing is not possible. Why do you keep asking these stupid questions?

Some people do not compare every symbol of address and watch for example only last 4 symbols and can send funds to scammer's address.
That's simply because people are often in a hurry while at it, during transactions. It's good to suspend everything one is doing during transaction. That's what I do. I'm never in a haste because I know once a mistake happens it's goodbye to my funds. I do take my time to check the first four/five letters of any copied wallet address I'm sending or withdrawing to. I do same for the middle and last four/five letters too. That's if the funds involved aren't much. If I'm doing a heavy transfer, I take my time to run a complete check from the first letter to the last before hitting the send or withdrawal tab. I'm conservative like that and I haven't regretted any bit of being conservative.

You don't even have to do that. Unless hackers have full control of your computer or phone, it's enough to copy paste address from the exchange, if you're sending to exchange. If it's your address, also copy paste, or use address book in your wallet. This kind of attack is effective only against people who don't take security seriously at all.
7  Alternate cryptocurrencies / Altcoin Discussion / Re: ON-CHAIN ADDRESS POISONING ATTACK Newest Type of Scam on: December 05, 2022, 03:14:50 AM
On-chain address poisoning attack is the newest wallet address attack which the attackers use in steal stable coins from their unsuspecting victims on both BSC and Ethereum network. In the attack, the victim unknowingly send funds to the attacker's address and over $1.6M stolen in that regard from December 2, 2022.
The details of the attack and how to prevent yourself from being a victim is here. https://rb.gy/tplvuv.

How do they know 1.6 million have been stolen?
8  Economy / Scam Accusations / Re: I got scammed out of 100000 dollars by fake 0 dollars withdrawal on BSC on: December 03, 2022, 12:26:01 PM
Seems like a very low effort low probability "attack" if you can even call it that. And someone hit a jackpot.

All transactions above some amount trigger 0 dollar transactions within few minutes. It's a massive attack that has been going for some time. Just look at the block chain. Even if it happens one in a million transaction, it's still profitable and scammer makes money.
9  Alternate cryptocurrencies / Altcoin Discussion / Re: Binance smart chain and 0 dollars transactions attack on: December 01, 2022, 01:12:29 PM
Those transactions send 0 tokens from possible victims wallets to scammer's wallet. It's possible to send 0 tokens from your address without private keys because the system accepts them because transaction is zero.
-cut-

Ok, i would liket to see anyone proving this as it sounds absurd. Even asking this makes me sound like a fool but:

Can someone make transaction from this address to literally any address without having private key for that address?

And please explain to me why i can't find info on something even related to this or why no one is talking about this? Can you also sign messages with other people's wallets while you are at it?


0 tokens can be sent by anyone. it is discussed here

This address had USD transaction.
https://bscscan.com/address/0x568ea44e79f404186409fb743e2b25c3ef49426c#tokentxns

Here he sends 2751 dollars to somebody, maybe his second address, or exchange.
https://bscscan.com/tx/0xb5ae05099b8197f1a6dd01d02b27511f23b4ab4625a8356cb92c249fdd8b7b09

The receiver is
0x3A06a19ee040322edF79e259e9830B02a65020b6

Then the scammer sends 0 dollars from 0x568ea44e79f404186409fb743e2b25c3ef49426c. He doesn't have private keys. But because it's 0, the system accepts it.

The scammers sends 0 to his own address
0x2b63c5514da212b24433b7bfe3ccac2b41f020b6


This address is similar to
0x3a06a19ee040322edf79e259e9830b02a65020b6

So then the scammer hopes that the owner of 0x568ea44e79f404186409fb743e2b25c3ef49426c sends to 0x2b63c5514da212b24433b7bfe3ccac2b41f020b6 instead of 0x3a06a19ee040322edf79e259e9830b02a65020b6.

Those transactions send 0 tokens from possible victims wallets to scammer's wallet. It's possible to send 0 tokens from your address without private keys because the system accepts them because transaction is zero.

The scammer creates address that is similar to address you sent tokens to. For example if you send 1000 Tether USD to you binance address ending with 12345, then the attacker send a minute later 0 Tether USD from your address to his address that looks like your binance address, it also ends with 12345. Scammer hopes you copy paste his address from bscscan and he hopes you send to his address instead of your binance address.
12  Alternate cryptocurrencies / Altcoin Discussion / Binance smart chain and 0 dollars transactions attack on: November 30, 2022, 11:09:26 AM
There is an attack going on where transactions are created that show transactions going out of your account that have 0 tokens moved.

The attacker sends 0 tokens from your address without your private keys. The address is very similar that you send tokens to. Then a user copies address and accidentally sends tokens to scammer.

Here you can see 20 such 0 token transactions.

13  Alternate cryptocurrencies / Altcoin Discussion / Re: Why such high fees in ETH? on: August 27, 2021, 04:34:47 PM
Actually, if we have blocks just slightly over 50%, it increases gas fee very fast. Only after many blocks that are almost empty or below 50% does the gas fee start to fall to reasonable level.

I suspect it's all just for purpose of manipulating the price, it's not about users. Greed has taken over, now all they care about is writing news about how much ETH they burned this day or this week!

Also notice that miners still get their fair share, but the system is robbing the users, only because they want to rave about burning ETH. Miners are still winning, price manipulators winning, users losing.

Good, now use your superior intelligence to connect this:

Quote
With EIP-1559, the base fee will increase and decrease by 12.5% after blocks are more than 50% full. For example, if a block is 100% full the base fee increases by 12.5%; if it is 50% full the base fee will be the same; if it is 0% full the base fee would decrease by 12.5%.
https://metamask.io/1559

And this:



Now call me master!

You're a slave! But seriously, thanks for the reply. So that's what the algorithm for the base fee is. I wonder who came with that formula, because it seems that even though we're not close to 100% capacity, yet this formula has lead to very high base fee. Do you know who invented and enforced this formula onto gas fee structure?

I think it's detrimental to users, putting that threshold somewhere above 50% would be better.
15  Alternate cryptocurrencies / Altcoin Discussion / Re: Why such high fees in ETH? on: August 26, 2021, 01:46:09 PM
Why do you have to reply if you have no idea what you're talking about?
Why you act like an asshole where some random guy trying to help you to figure out this phenomenon? That's a wonderful way to keep people from posting here.
If you are so smart, why you asked this question, and not figuring out by yourself. OMG people nowadays.

Quote
A final important note is that blocks themselves are bounded in size. Each block has a target size of 15 million gas but the size of blocks will increase or decrease in accordance with network demands, up until the block limit of 30 milion gas (2x target block size). The total amount of gas expended by all transactions in the block must be less than the block gas limit. This is important because it ensures that blocks canít be arbitrarily large. If blocks could be arbitrarily large, then less performant full nodes would gradually stop being able to keep up with the network due to space and speed requirements.
https://ethereum.org/en/developers/docs/blocks/

You are looking at the wrong metric smartass...

 

I'm not smart enough to figure it out, that's why I'm asking. So if someone has no idea what the answer is, they must answer some irrelevant gibberish anyway? OK, got it.

And by the way, why are you replying again with irrelevant gibberish? Yes, I'm looking at the right metric.

Look at this block, it's basically empty:
Gas Used:
416,504 (1.39%)
https://etherscan.io/block/13101022

Yet the gas is very expensive.
16  Alternate cryptocurrencies / Altcoin Discussion / Re: Why such high fees in ETH? on: August 26, 2021, 01:04:15 PM
Probably it's not because of how many tx, but the computation power, thus you can have blocks near empty but they are resource hungry and congest the network.*

*It's only based on my common sense, it's like token transfer needs more gas than moving ETH, so probably minting and moving NFTs also require more gas.

This is not true. Did you even look at recent blocks? Some blocks have about 10 normal transactions, while during bull run we had 10 times more, and the network handled all of it. Why do you have to reply if you have no idea what you're talking about?
17  Alternate cryptocurrencies / Altcoin Discussion / Re: Why such high fees in ETH? on: August 26, 2021, 12:53:23 PM
I think that miners also have a role to play in all these, and hence the reason Ethereum team are trying their best to ensure all these issues like gas fee

They are doing the opposite. With London fork the fees only went up. The team doesn't care about gas fees one bit.

Dapps and DeFis are the driving force of the gas price going so high in Ethereum economy. Every transaction is being charge and the gas fees rely on how many transactions are executing in the network and access rates are off the roof

This is not true. The blocks are not filled, with increased gas limit, now at 30,000,000. Many blocks are empty!

https://etherscan.io/block/13101042
Look at this block. It used only 6% of gas limit!

We don't have capacity problem at all right now.

And still, no one answered my question, what is Base Fee Per Gas and especially minimum gasused multiplier?
18  Alternate cryptocurrencies / Altcoin Discussion / Re: Why such high fees in ETH? on: August 26, 2021, 11:30:11 AM
The gas will be based on how crowded the blockchain and it will be also using the average fees in the network that will be determined from the all of transactions that already processed by the block/mempool.

This is not true. The blockchain is not crowded at all. Did you even check the blocks? We have it running half empty. Last time network was running half empty in June, gas was 3 - 10 GWEI.

Now we have almost empty blocks with 85 GWEI price. There is some base fee that is added for some stupid reason to make it super expensive.

There is this "Base Fee Per Gas" in all blocks now. Do you know what it is?
19  Alternate cryptocurrencies / Altcoin Discussion / Re: Why such high fees in ETH? on: August 26, 2021, 06:46:12 AM
This block for example was 4% filled. It's almost empty. But still very expensive gas.

What's going with gas fees? After the London fork, the gas fees only went up. They raised gas limit, and the blocks are half empty, even 5% - 15% filled, but gas fees are through the roof! It's not about limited capacity right now, yet it's very expensive. What is reason for that?

And what is minimum gasused multiplier?
People have been buying lots of NFTs and that has had an affect on gas prices. A lot of people have moved to Mintbase on NEAR protocol because the gas fees are lower and the amount of profit you get is higher. Opensea also works on Polygon.

No, blocks are half empty. Sometimes blocks are 5-10% filled. Gas fees should be super cheap now.
