  3. Re:ISP POV- NOT on ISPs Victimizing DoS Victims? · · Score: 2

    Well, the part you [SNIP]'ed out did say I'd never killed a user that hadn't broken the AUP (usually they had flooding/cracking/etc tools or eggdrop scripts for doing the same).

    >Come on now, this doesn't make sense. Killing the target won't help during the attack
    >During the attack you:
    >1. Find the source or sources of the DOS
    >2. Block/Filter this at your guardian routers
    >3. Communicate with the source ISPs.
    >4. Other net admin steps I forgot.

    I suppose I should have said a small ISP, but anyway..

    It's impossible to find out the true source of the attack is, but filtering it out at the router could help. The problem is when the attack is big enough to kill you at your router -- which is when you bring in the upstream router. But, It can be difficult to get your upstream ISP to filter out all the (many) spoofed addresses before the DoS ends -- and anyway, they'd just move on to another misconfigured broadcast address..

    When did I say I'd kill them during the DoS?
    I'd terminate the account after the DoS stopped, and I could have a look arround to find the actual CAUSE of the DoS -- and proof it was their fault. I might terminate a user if all they did was provoke the attack, but only if they did it repeatedly, and I knew they had actually done something to provoke it.
    The bottom line is, the user is affecting OTHER paying customers as well, and while I definately treat DoSes on a case-by-case basis, it's hard to do much more than contact the admins of the amplifying network, and ask them to fix it, and see if they have any logs which might help trace the real attacker.

    The only problem is figuring out just where we draw that line.

    Asking them to stop is a great idea.. Until you realise your whole network is being killed by the DoS -- then you just want to kill the attacker, the victim, or anyone nearby.

    Hmm, that might help, a bit. The problem is, it'd probably be very expensive (CPU time-wise) for the router to update/check/etc, making the routers EVEN MORE expensive ( £/$/etc wise )...

    Also, the ISP probably won't be upset by a user being DoSed, unless the bandwidth used by the DoS is affecting the whole ISP.. at that point, the attacker could just move the attack from 1.2.3.4 to 1.2.3.x, and fill the entire subnet's quota, preventing ANY traffic at all reaching the ISP, even if it could *physically* fit on the link, the router would drop it.

    OK, so maybe this isn't the magic solution I thought it was when I first read it [unfortunately] :(

    If you survive, it's not much of a Denial of Service.

    Maybe you piss off some 14 y/o on a 56k modem, who decides to do something like pingflood you with "ping -f", that won't hurt the ISP, and it'll only hurt you if you use a 14.4 modem (otherwise, it'll act like a big download).

    If you *really* annoy some guy who thinks he's a 3l33t h4x0r, then they'll probably smurf you, or your ISP. A big smurf attack can generate a *LOT* of traffic, which can easily bring down a 10mbit pipe, depending on the size of pipe, and the number of computers on the amplifying network.

    It's like a pingflood, but from 100 computers at once (or however many pings are returned from the broadcast address of the network), and it can bring down a network easily (it's also the reason for the continuous netsplits on Efnet, and the reason lots of server admins are delinking -- to get the hell away from them).

  8. Think of this from the ISPs point of view on ISPs Victimizing DoS Victims? · · Score: 5

    As a co-admin of a shell/webhosting server, I can't see what else they are supposed to do. I have never terminated a users account because they appear to be the victim of a DoS (most shell users who get DoSed do SOMETHING to deserve it, hell, so do most shell users who DONT get DoSed), but I have terminated many accounts which were committing DoS attacks..

    I have had an entire networked downed for over 24 hours because of a DoS, which means the victim loses out, everyone else loses out, and we lose lots of money -- especially when a shell user brings down the webhosting side of things.

    Anyway, if the user is being continually DoSed, having an account with the ISP won't do them much good, would it?

    As for getting the police involved, well, a smurf is virtually untracable, the source addresses points back to the (misconfigured) amplifier network, which is totally innocent, and the packets they receive are forged to come from the victim's computer. It's difficult to filter smurfs without breaking things like ping, and if the ISP is paying per Gb, DoSes can be expensive.

    The ISP has to pay for the DoS traffic (which could cost more than the customer is paying), and also might lose other customers/potential customers because of the reduced performance.

    The customer loses their account (possibly their money, though if the ISP has no proof the victim did anything, I'd expect them to at least refund the remaining subscription), and maybe their e-mail address.

    The ISP's AUP/TOC usually allow them to
    terminate your account for little, if any, reason, and in this case, they have a pretty good reason.

    Free speech is great, but should you be sued just because *you* don't want to risk your livelyhood/life/whatever to protect it?

    It is in effect a stats error. The problem is:

    To be fair to everyone, everyone is given credit for the block, if it is a 'virgin' one, or a reissued one (however, not if it is a duplicate block, they are filtered by the keymaster before reaching the stats).

    The way the stats server currently counts the percentage complete, is simply counting all the blocks it is told have been completed, and dividing that by the number of blocks in the keyspace.

    Because people are being credited individually for duplicate blocks, the total no. of blocks done includes these duplicate blocks.

    To fix it, the stats need to know if a block has been reissued, and if so, only give credit to the participant -- but not the whole effort, as doing the same block twice *doesnt* increase our keyrate.

    Second: nugget (David McNett), released an announcement stating that there had been a problem with the keymaster generating invalid blocks, resulting in 25% of the keyspace being duplicated.

    So, one remaining question is, are they still sending out ~10% 'verification blocks'? Or have they abandoned that to allow us to complete the project faster?

    We have reached 112% due to verification blocks and could reach 140% due to 25% of the keyspace being corrupt. However, if 12% of the 25% new blocks are duplicated, then we could reach about 155%...
