Just check if any system files have injected any different byte arrays into the systems memory. Checking if anything has been written to the VirtualMemory or any space has been allocated in the memory.

If it were that easy, anti-virus software companies would be out of a job pretty quickly. Cheesy

You buy a "botkiller". It kills all the other peoples infected file besides yours so the zombie is all yours.

That I would trust even less than the botnet computers themselves. That would need to be something you yourself programmed, and even then it'd be difficult to tell what other backends were and weren't installed on the compromised computer.

Wow, you really did the math on that one?

Lol, I'm just pointing out how much it would cost if you went the non botnet way. I don't have the technical prowess for programming a million bots to hash for me. I hash my Litecoins through legitimate means. Wink

The only problem I hate about checkpoints is once we restore and the coins are gone, the coin is over.

There is another massive problem with the litecoin botnet scheme too -- when people realize that they can make lots of money using a botnet to mine litecoin, the price of renting a botnet will increase tremendously based upon demand and there will be intense competition now for "zombie" computers.

The other thing is that computers you get from a botnet are usually shared as far as I can tell, so you're competing with other people also using the CPUs.

My personal guess is that if you purchase a large botnet you'll probably hit less than a KH/s per computer because they're already busy chugging out all kinds of shitty code for other people. If this is the case, you're looking at $100k USD+ to attack the network.

You guys wanting to destroy the LTC network... GOOD LUCK! Roll Eyes

*draws line in the sand*

To gain 51% of a 2,814,369Kh LTC network, you would need 1,435,328.19 Khs

- buy 2051 ATI 5970s, about $250 each used = $512,750
- buy 513 motherboard/cheapo cpu/2Gb RAM, about $125 each used = $64,125
- buy 513 1200W PSUs, about $150 each used = $76,950
- shelves/racks for 12 rigs each at $60/each for 513 rigs = $30,780
- PCIe risers for 2051 cards at $3 each = $6,153
- 240w PDUs for 513 rigs= $6,000usd
- an electrician, rental property with commercial 3 phase 240volt electricity and data center-like air conditioning = $75,000
- electricity per 24 hours with 513 rigs w/ 4 5970s each = $1,354.32 per day for rigs power

TOTAL: $771,758 upfront and $1,354.32 per day for electricity of the rigs alone, not factoring in the AC.

You could probably do it for less or more, but this is a rough estimate.

Until the number you offer is at least 1.5x this price, then I decline your offer. Wink

I just 51% attacked the network and succeeded! However because I like everyone on Litecoin I decided that with my new superior LTC blockchain, I would leave all the balances the same, and because I don't believe in stealing I didn't give myself any free coins.

Well, you owe me $1000. You can pay in terracoin to my sig below.

Right now it'd cost somewhere around $20,000 to buy a botnet capable of performing 51% attacks against the Litecoin network.

However, you could make $200,000 from ripping off BTC-E's LTC/BTC buy orders alone.

$20,000? Have you ever had a botnet? Do you know how much one infected computer costs, especially when spending $500?

If you're spending $500 on installs, it's $0.005 per install. Each will probably get 3-5 kH/s assuming that they're shitty.

$500 is 100,000 installs, yes, 100,000 infected computers to mine for you, getting you the speed of 300,000 - 500,000 kH/s on the whole muthafucking network!

I'm sure $500-$700 of installs could practically destroy LTC, but, who actually has such an amount has an amount? No one.

It seems that you in fact contribute nothing. I'm very pleased that you hold lots of slow betacoins hashed on proprietary hardware.

It's called a *checkpoint*, you little idiots. Have fun, children.

Seems some of the ummm....Less aware, let's say, have become a little anxious of late.

Cheesy

$700 to destroy a $10,000,000 currency. I'm suprised no one has borrowed a lot of litecoins, shorted them, and done this already. We don't even need a bounty on it. A checkpoint won't do anything to stop a chain fork. It could undo the fork after clients upgrade, but it won't help against a sustained 51% attack.

Wow you are a dumbass.

1. A checkpoint would ensure that your fork would not affect current users of litecoin.

2. "it could undo the fork after the clients upgrade"...right like 50% of us are going to upgrade to your bullshit forked code? LOL!

3. You OP already has shown how stupid you are in thinking that $500, or even no $1000 is enough to get someone to want to "ATTEMPT" to 51% attack Litecoin.'

4. LOL, ROFL, FAIL MORE Grin

Lets assume for a moment that the $700 is right (its not), what would be your incentive to destroy it? Indeed what wouldn't be your incentive to just mine it and sell it, like everyone else? If you really have over 1.5Gigahash of Mining power- you could earl a shit load of money just mining and selling. You would have to be crazy to want to destroy something that is literally printing you money.

Anyway, the cost is higher then $700 because it's a free market and the people who control these botnets (from whom you presumably would rent it from) aren't stupid and are well aware of Litecoin/Bitcoin. Where do you think so much hash power on the litecoin network comes from in the first place? Botnets, thats where. So you're not going to be able to rent the botnet for cheaper then the botnet owner can simply mine litecoin themselves.

That said, this is why ASICs are so important.

The price quotes are from here:

If you got 4 KH/s per bot and paid $0.02 per machine, you would need $15,000 to attack the network right now.

Keep in mind that's also 750,000 computers -- it's unlikely you'll find any single person with a botnet so large to offer you.

Mmm, that's not exactly how it works, nephew Grin

. Perhaps I am mistaken (need to read up on this again, the BCX drama was a while ago), but you would need to maintain over 1 gh/s for a rather long time. So, I think ~ $2k min.

Remember, you must fork and then hash your little broken chain off to the side and then get the network to accept it as valid. Coblee can drop in a checkpoint, too.

You guys....Don't start the BCX noise again Roll Eyes
