there are ways but its very expensive

Asic Miner solo mines at 30Th   our entire pool mines at 7.5Th   .  Close to the right numbers.  BTC guild mines at 45Th  as does 50BTC.


http://static.blockchain.info/pools.png?format=png   

  So if I DDoS attack;

1) BTCguild

2)50BTC

3)bitminter   

and I can not attack AM  does AM gain by this? 

 Lets say I launch 3 attacks today Against
BITMINTER
BTC guild
50BTC    make the attacks last for 12 hours. 

 Would not Asic Miner get to grab the last blocks  at the lower diff of 15 million  right now there are 23 or 25 blocks left.  So if the 3 pools I mention get attacked AM would be like a god for those last 23 or 25 block.  Correct?

I see BTC as the super highway and alt coins as taxis and trucks needed to move transactions.

Any time a pool is down, other pools pick up a larger proportion of the total hash-rate, because the total hash-rate shrinks.

This is partially offset by the use of backup pools, but Bitminter is particularly susceptible to this type of attack because so many people use the java client. (And if your backup pool is also under attack.)

So you are technically correct that if the top pools are all DDOSed at the same time, ASICminer would benefit. Smaller non-targeted pools would also benefit, but not to the same extent as ASICminer because their total hash rate is so low.

No, reducing the global hashrate doesn't have any immediate impact, as the difficulty is still the same.

Your chance to make blocks is only affected by your own hashrate and the current difficulty.

If they ddos a substantial amount of the global hashrate for a substantial amount of time then it may affect the next difficulty adjustment. You would have to ddos a lot to have any noticeable effect. Doesn't seem to be a likely reason for the attacks, unless the attackers are confused about how difficulty works.

I do not see how anyone gains by a DDoS attack on a pool, because the hashing just gets directed elsewhere temporarily.  

This. Wherever the hashing gets directed benefits. A lot of bitminter people use the java client, so their hashing doesn't get redirected, it just goes idle until the pool is back up and they reconnect their miner.

Quote
In that case, again they are just wasting their time because they only cause a disruption for the seconds it takes to connect to a backup pool.

If the backup pool is taken out at the same time, their hashing would also go idle. The scenario given was an attack against several pools simultaneously. To avoid the scenario, you could have a long string of backup pools, but in most cases one or two backups are sufficient and most miners don't have more.

Edit because DrHaribo posted while I was writing:

This is a good point. You don't find any more blocks, your opponents just don't find them. It could prolong the next block readjustment a little, allowing you to find more blocks before difficulty readjusts. I don't think this is what is happening, though.

How feasible is it to register one's IP with Bitminter, to create a whitelist of IP addresses. Traffic from all other addresses not in the IP whitelist can then be dropped by the edge routers. Probably not realistic. But an idea nonetheless.

Not feasible at all. Many users (myself included) have dynamic IP addresses.

VPN+NAT (Proxy) to core bitminter server from IP located in US for instance. When Dos attack is launched, core sever shuts the VPN to attacked US machine and fires anothewr one to EU IP which is published here + DNS changes.

So attackers will be not be so flexibble and they will be cutted of completely as long as real IP of bitminter stays hidden always. DOC just needs a couple of VPS (empty boxes) to be exposed all over the world  Wink

Anyone have thoughts on the motive behind these attacks? Is there a shakedown coming in the near future? Who is benefiting at this moment, when we are down?

well now that difficulty has moved to 19 mill the attack will stop soon.   Dr H. I did not fully explain my question earlier .  I need to break it down further.  How much 7Th of your 7Th is like my piece 0 backup pool no shift just lost hash.  I am all java client and when you get DDoS I get 0 mining. So the last 25 blocks at 15 mill diff I got 0 BTC.   Now I am fighting against 19 mill.

 Next part because no backup pool is my choice.  

 If BTC Guild and 50 BTC and Bitminter go down for the last 25 blocks at 15 mill diff.  it would be a lot of hash power around  90Th maybe 100 Th  leaving 50 to 60 th left of which asic miner has 30-32th so for those last few blocks 23-25 they have easy pickings. Since even though the diff is 15 mill they have half the available hash rate. This gives them 12 or 13 of those 25 blocks.  No DDoS the last 25 blocks at 15 they have 30 of 150 or 20 percent they get  5 blocks.  5 blocks vs  12 blocks.   I realize that the  DDoS would need to be against the top 3 pools  but I am sure my idea has real merit.    This means any large share holder of AM has a big incentive to do  simultaneous 3 pool  DDoS attacks.   I sure this logic it correct.

  For that matter   this top 3 pool attack at any time leaves AM in the catbird seat.  Not good.

I see BTC as the super highway and alt coins as taxis and trucks needed to move transactions.

We desperately need a backup pool, I had to temporarily switch to slush's pool for now until you can get yours back up and running.

BTC Guild has found 11 out of the last 25 blocks, which equates to a 44% of the last 25 blocks.
 

same idea as mine except the gainer was BTC Guild  not   AM.


  the concentration  of hash in 3 spots BTC Guild , 50 BTC , AM ,  all at 32 Th plus then bitminter at 7 Th  makes these attacks a bad thing.  

If you know you are able to do this to a few of the top miners at the last 20-30 blocks  you get an edge.   it is very easy to fix have an  auto switching  agreement among the larger miners/pools.  end of DDoS incentive.   this DDoS  issue along with the crackdown on moving coins to cash will kill off BTC if not addressed.

Simply use backup pools and the problem doesn't exist ... it's been well known for a VERY LONG TIME ... so if software STILL doesn't have it ... use something written in the last ... 18-24 months that does ...
