back to article Irish ISP downed by DDoS

Ireland's largest internet service provider Eircom is blaming hackers for its second bout of recent downtime. Eircom customers could not get online for much of yesterday evening, although the firm said full access was restored from 11.15pm. Just the week before many Eircom subscribers were sent to the wrong websites thanks to …

    I blame IRMA

    Maybe it was IRMA trying to spy on possible uploaders. Or is the total lack of investment in the company ever since it was privatised beginning to show and ye olde sefvers are beginning to crap out...

    Hackers, or incompetence?

    Personally, I wouldn't call a DDoS, hacking. In a traditional sense would be taking control of a remote computer by Backdoor Trojanal activity. A DDoS is usually from a Bot Network, which is created by becoming infected, usually by a trojan, and usually from iRC ports and servers.

    Eircom should be in a position to block or fend off a DDoS attack, as control of the packets is something better handled at network, rather than by a firewall, and I know I've oversimplified it, however an ISP should have the abillity and bandwith to handle a doubling of traffic with ease.

    And, normal service being resumed, sounds more like a drop off in the DDoS, rather than something that Eircom itself did.

    Perhaps, it is time that Eircom reviewed it's own policies and inadequacies in handling what was by their own words, merely a doubling of traffic, hardly SYN flooding at it's optimum.

    I know why

    It is due to them being the 'music' industry's bitch, folding against their baseless and unenforceable threats instead of letting the 'music' industry humiliate themselves in court

    Not really a downed network.

    I'd agree in it not being called a hack. And a doubling in requests shouldn't topple a network. Especially seeing they are only DNS requests.

    Now correct me if I'm wrong but all that was wrong with the Eircon network was that their two dns servers were under attack. Shouldn't that mean that direct IP traffic or users that had an alternative DNS service such as OpenDNS should have been ok?

    And what sort of ISP are they, who can't filter their logs to see what IP addresses were DDOsing them.

    is there anyone here who doesn't know why eircom is being targeted?

    Cos i do.

    one has to suspect that eircom does 'n' all.

    They may not know....

    ..but they must suspect, it was the first thing I thought of as I read the story.

    ... a link for you at the back under the rock that may not already know

    Eircom customers vent their anger?

    Hackers? More likely disgruntled customers pissed off at their appalling service managed to find some way of venting their anger at Eircom for once.

    The Eircom statement on the affair is a laugh. "No customer records were exposed"- it was a DDOS attack guys- why would anyone imagine data was exposed?

    Unfortunately its yet another manifestation of the ineptitude of Eircom and their broadband services. I left years ago- thank god there are alternates.......

    Seems to just be DNS again

    I'm with the wankers, but I use OpenDNS, and I've no issues.

    DNS hacked?

    According to the forum posts, or this:

    the DNS servers were sending people to porn sites during the first attack (last week). Does this imply the DNS servers were hacked? Did eircom perhaps fail to apply certain recent critical DNS patches? Or could the high traffic volumes alone have caused this?

    Just manually set my DNS addresses to the old Indigo ones and I was up and running with minimal downtown.

    expertise ??

    "Eircom has been in contact with other operators in the Irish market to collaborate and pool technical expertise in this area."

    This should actually read... They don't know what the hell it was and need help as they are clueless when it comes to operating a network.

    Rant over.

    Eircom still has customers???


  16. pee'd off


    This attack has been going on for over a week, and all that eircom are saying is that they are experiencing difficulties .......

    eircom are saying that it is only DNS, yet most customers are not even getting assigned an IP address from the DHCP servers .... lines being dropped all over the place .... my recommendation - find another provider

    If that is to suggest, AC, that Ireland and Celts can produce serious change in a stealthy, often gradual, manner; intending to entrap and enchant, then I would agree.

    I did ask if they thought the attack had anything to do with their attitude to P2Pers and was told they had no evidence of that...

    As always enjoy your posting. And that is complimentary.

    As the original poster, I would like to point out to you a glaring mistake in your reposte.

    Insidious, is a completely different word, from Obsidious.

    obsidious adjective. rare. E17.

    [from Latin obsidium siege, from obsidere: see OBSESS, -IOUS.]

    Besieging; besetting.

    Thanks, AC Posted Wednesday 15th July 2009 10:12 GMT, a Jung Freudian mistake and constructive error which avoided conscious delivery. ie I didn't notice the unconscious transposition, which as you say, is complimentary.

    dns my i

    Haircom don't even know what hit them. When we were dealing with them (past five years) the DNS servers would used to sit down regular every 7-8 weeks or so because they cached-up - couldn't see in or out through the node unless using IP addys. Ridiculous, I know, but you could set your watch by the brownouts.

    Heard their servers are kept in a block god-knows-where, down the back, climb the ladder, move the teachests, swipe the cobwebs, hit with a hammer. That's if you can get a gentleman on a penny farthing to go down there and he has the keys.

    Typically takes 24-36 hours to flush/reload to fetch DNS again. Suffice to say, it's superfluous to hack Haircom as they'll balls it up themselves without trying and won't even know they have a problem. You don't need a hacker to redirect you to a pr0n page.

    This sounds like one of those head_scratching moments of Haircom wonderment and awe rather than the first strike in a Sino-Russo-nKoreo attack on Fortress Dublin.
