SCO Group Web Site Attacked Again

FreeLinux writes "With not much SCO news today, it seemed that this story was needed - Reuters is reporting that, SCO is again suffering under a DDoS attack that has crippled their web site and email system since Wednesday morning. For the third time this year, the SCO Group's Web site came under attack, apparently by hackers unhappy with the company's legal threats against users of the Linux operating system. The denial-of-service attack started at 6:20 a.m. EST Wednesday and continued through the day, said Blake Stowell, spokesman for the Lindon-based company."

SCO claim e-mail and other services were compromised which do not use the TCP SYN/ACK and are not therefore vulnerable to this attack (when on different servers (which they are, see groklaw for a list). ftp.sco.com remained up, despite being on the same subnet, and smtp.sco.com would respond throughout the duration of the supposed 'attack'.

    I should point out, this has pretty much been covered by Groklaw already and my methods don't vary too much from those already posted by them.

    SCO claims their email and web servers are unavailable because of a DDoS attack that has also infiltrated their Intranet and affected helpdesk services as well as other internal services. If this is the case, then it is more than just a DDoS they're suffering, or they are negligent in the highest order for failing to take simple steps to ensure a risk mitigated environment for conducting business within.

    Lets start with their Mail Server.
    Everyone has a backup mail server, usually hosted by a 3rd party to ensure that if your primary mail server is offline for any reason, mail can still be delivered successfully. The fact that SCO claimed their mail servers were unavailable suggests they either failed to purchase this extremely basic service or their setup is absolutely wrong by anyones standards. The purpose of multiple MX records is for this exact situation. You start with a high priority MX record (say 10) and work your way down the order (usually in steps of +10, so the secondary is usually 20).

    Their Web Server
    Their webserver is hosted on exactly the same subnet as their ftp server. However, during this attack, their FTP server has been available to anyone thats tried to connect to it. If they were suffering a DDoS attack of the proportions that SCO claims, this server would also have been affected and taken offline. Yet this is not the case. This blows open entirely the philosophy of a DDoS attack without any of the further evidence.

    SCO has alluded to the fact that the attack is a basic SYN Flood. A very simple and old attack that has been blockable by nearly every appliance and OS for the past 3 years at least. Yet if they are suffering as they claim, then they are guilty of negligence for failing to apply patches or even configure their platforms correctly. Its very easy to turn the SYN Cookies on in Linux (sysctl isn't rocket science) and just as easy in something like a Cisco Router/PIX Firewall or a Checkpoint Firewall.

    The claims that this has adversely affected their intranet suggests that the intranet is in some way exposed to the Internet. Even more alarming is the fact that it disabled their Helpdesk services for a period as well. This would suggest that their network has absolutely no perimeter protection of any kind. The smallest flaw in a product they use could apparently be used to access their core network infrastructure. Isn't that where their source code and IP documentation are kept? I'd start getting very worried about now if I were an investor.

    Due diligence is a core principle of any company. That includes ensuring that the services relied upon are securely and properly setup and maintained. If SCO truly has been affected by an attack of any kind on the magnitued they're claiming, then they should be legally responsible for the results of their failure to perform due diligence. (However, IANAL so don't quote me on legalities, especially given I live in NZ, not the US).

    In short, the supposed attack on SCO does not add up at all. In fact, if they are being attacked this time round, they are in serious legal trouble themselves if their reports are accurate.

    I would also question why they have released this to the press as a Press Release instead of getting on with fixing the problem as quickly as possible. Also, how is it that their mail services are now restored, their FTP server never offline, yet their website remains offline? Surely, a DDoS would affect both.

However, the first is completely and normally responsive, while the second is entirely unresponsive. This is not in any way characteristic of any sort of modern flood-type denial-of-service attack -- that is, a DDoS aimed at flooding the network itself. Whatever is disturbing SCO, it is not a DoS of the sort they evidently believe it to be.

    Unfortunately, SCO has taken the "cargo cult security" measure of blocking pings, so it is not possible to gather any information about their disturbance in that fashion. I suspect that the best method to gather information about SCO's disturbance is, in fact, for SCO to fully and legally respond to IBM's discovery requirements.

    ("SYN flood" is obviously wrong. Although some firewalls and IDS still report TCP-based DoS floods as "SYN floods", the condition that used to be associated with SYN floods has been fixed in current operating systems. Unless they are running a system old enough to be called grossly negligent, they aren't susceptible to TCB starvation. The current unavailability of www.sco.com looks more like someone tripped over the Ethernet cable.)

      The FTP server being up proves nothing. SCO is claiming that they are under a SYN attack, which has a relatively low bandwidth costs, and if targetted purely at their webserver and not exceeding the total bandwidth will leave the FTP site up. Basically, for those that don't know, a SYN attack works by flooding a server with requests for a new session, usually with a spoofed source IP. The server *has* to allocate some resources to this request, respond with a SYN-ACK and wait for the ACK (which never arrives). Enough SYNs (the packets are only a few dozen bytes) and the server will fall over.

      So, on those grounds, I'd be prepared to accept that SCO is telling the truth and they are indeed under a DDoS SYN attack against their webserver. However, as normal for SCO, they then go and overcook the situation and claim that their internal network and Intranet has been hit as well. The only possible way this could be the case is if they are using the same server(s) for their public web as their Intranet which is one of the dumbest possible things you could do.

I'm getting a little nervous sending out these funny packets as I don't want anyone to accuse me of anything, but everything indicates that the machine is completely offline. If they allowed some ICMP replies through upstream, receiving a reply would show that the machine is actually online, but somehow cannot handle TCP requests (and the problem is not bandwidth as shown, so it would have to be something wrong with the host, such as a firewall rule); if they allowed through ICMP replies and the machine did not respond whereas others on the subnet did respond, it would show that the machine is almost definitely offline unless it has a more restrictive firewall than the other machines (very unlikely given that this, as-claimed, could have been prevented with syncookies). As it stands, one can only say that the machine is very likely offline (unplugged or turned off).

    Early in the morning, someone was exploiting a rooted SCO corporate web server. But they tripped over an intrusion detection alarm. System/network administrators were notified.

    Per their company policy, they shut SCO's entire network off from the entire world. "Internal mail servers and other support servers were unavailable." After a few hours, they determined that the intrustion was limited to the main corporate web server. The web server was broken off from the network. Network connectivity was restored (but no longer having a web server). "The web server is under a denial of service attack."

    SCO employees begin the process of either restoring the existing web server from backup, or preserving the existing server, and bringing online a new server from bare metal. The process is expected to take at least twelve hours. An SCO executive informs at least one media outlet that they expect the problem to be resolved in some time after twelve hours. They're still working on it.

    This also fits what happened in August, when their corporate web server was unavailable for THREE DAYS. When it was brought back online, the content was reportedly changed in some areas. It sounds like an inexperienced bare-metal restore or an untested solution. Perhaps part of the web site was not retreivable via backup, and they had to recreate some sections from scratch.

    My theory, which I believe totally fits the facts, is that SCO has been rooted and does not want to admit this publicly. So the DDoS/SYN is their cover story, which is close, but doesn't fit the facts well enough to avoid suspicion.
