Cause of the botnet ( in response to " pajeet " exploit )

@haitch i was looking at the pools here http://blocks.burstxd.com/
and you can see a lot less blocks hit than in the past few days for sure...
Yeah, I think this due to really short DL's (the Botnet ?), causing the wallet to over estimate

@jant90 It's complete and utter BS.
I have Burst account X, I plot a single 500GB plot of nonces 0...Y. I also plot 100 5GB files for nonces 0...Y.
A nonce is computationally derived from your ID, the last scoop number, the value of scoop(4096). So both the single 500GB file and the 100 x 5GB files will have exactly the same data in them.
Which plot do you think will be more efficiently and quickly mined?
Like I mentioned (and the SPlotter author as well), it's not about the plots, nonces or scoops at all. Yes, the plots contain exactly the same data, there's no discussion about that.
It's about the algorithm that calculates the deadline from these nonces (= just the mining part). And yes it's also agreed that scanning the hard drive takes longer with smaller plots so scanning the plots is less efficient BUT the theory is that you will receive lower deadlines because of the relative position of the nonce within the plot files.
I haven't seen any admin or developer here or on Burstnation address that theory at all. Even Blago fully ignored the issues raised by the SPlotter developer and instead stated the same you did just now (plot data is the same / scanning takes longer etc.).
Maybe a miner dev can shed some light on this? They should know how the deadlines are calculated during the mining process I guess?

@jant90 It all Comes down to question whether the author of splotter is right with his assuming that the concrete Position of the nonce within the Plot gives you better Deadlines when they are more at the end of a plot than in the middle - or if there is no difference at all.
He has posted a pic over there here:
(first page, one of the plots is not like the others). I really would like to see comments on that and on the question if or if not this way of plotting give you ~5times better dl, thus 5times more coins - for the Price of having to replot your HDs and ruining them quicker by putting more load on them.

When you want blago's opinion on that you need to tag him ( @Blago ) !
From the first glance it looks like this guy made the old wplotgenerator out of the XPlotter. Wplotgenerator used the Stagger, which were simplified like sequential chunks of plots.
It just doesn't make any sense why this should be better or give better results.

@Marc exactly.

And that's the part that is complete and utter BS. The miner doesn't care where abouts in a file a scoop came from; the scoop is going to have the same content, and the miner is going to do exactly the same calculations if it's the last scoop in a 1GB file or buried somewhere in a multi terabyte file. The scoop has a value, that is mathematically processed to create a DL with no regard to file position. Scoop Y in Nonce X is always going to be Scoop Y in Nonce X and will always have the same DL.

@Blago LOL - quoting me at BN could get you banned ..... ;-)

@Blago @haitch But they are saying that nonces with index over 9,223,372,036,854,775,807 hit more blocks?
Or are they starting to count down from 9,223,372,036,854,775,807 ?

@gpedro it's complete and utter BS. SnakeOil.A scam. Mathematically impossible. The people spouting this crap are doing so from the place where crap comes from .....
-
@Blago Have you looked at the code? It's possible that it may be infected too? you know as trojan horse or something?
@haitch I think so too but I wanted to try and understand what they are saying...

The code looks fine, but the exe he's distributing as a release could be malware.
-
@gpedro i'd check the code - he add only 2 strings - loop, using "goto" https://github.com/SamuelNZ/SPlotter/blob/master/SPlotter.cpp#L312
(scool-boy programming style)
-
@Blago what about the actual exe? Did you check that? I can stand up a vm to profile the exe in an isoled environment, I guess.
-
@illuminatus virustotal - exe clear
-
@illuminatus That would be cool...
@Blago I guessed so too xD
-
@Blago right - but a virus scanner ( I assume you used that) would rely on a known signature of the file(s) - how do we know that running it doesn't install something else?
-
@illuminatus same way you know there is not a mugger down the alley in front of you. Little bit of faith and a little bit of caution...
Blago said the code was clean just added two lines if you don't trust the exe the author built you can build your own off the source. But IMHO if the author's exe was infected with a botnet spreading virus or trojan then his github account would get reported and dropped or flagged.
-
@Lunas considering the time from when he posted the code and this guy started the "bot" dont think they are same guy....
not sure he could have gotten 15 K + pcs infected that quickly cause wouldnt they still have to be plotted to get it to work?

@falconCoin it is not that hard to make a bat script i know you can make a auto number gen script or even a count to 819,200 add 819200+1 and loop. If he had lets say a bank network at his disposal. And was one of the IT guys he could from his 1 terminal place an automatic script to send a file to each pc in the network each file sent would be generated by a script and to run the plotter and miner and sent. Once on pc it would execute whatever and either download the 200tb burst file or run the plotter and at the same time it could run the miner set as a background service on startup using only 1 core 90% of the time nobody would even know it was there... it would use the terminals cpu and hdd.
To give you an idea most banks have terminals that are full pc with a 500gb+ hdd and an i5 or an i7 processor with 1-2 gig of ram and typically running a variation of windows server edition. A large school campus would have similar setups and yes the IT dept could launch on each and every machine a script to do this and it could even advance the starting nounce so it would not overlap...
The fact is however he did it the math of him bringing a network of 15,400 bots is viable and the evidence is sound. If he set the plotter to run in the background at low speed or after hours at full speed it would only take a few hours for a modestly powered i5 to make a 200gb plot...
Infact i wouldn't be surprised if his botnet only grew bigger or if it disappears for periods of time to prevent his discovery by his employers or the faculty.
