  • F-secure list of sober virus urls

    When the news was first out that an antivirus firm (f-secure) had cracked the psuedo-random algorithm that the sober worm uses to determine where to download “updates” from, they said that they had previously notified German authorities where the free hosting sites were located so that they could deal with the sites. I did find that they have announced a list of the addresses for the January 5th update (and the January 6th as well.)

  • How much is a 0-day vulnerability worth?

    ZDnet has this article today of an ebay auction for information on a Microsoft Excel vulnerability that the auction-seller had notified Microsoft of.

  • DRM => spyware

    Freedom-to-tinker once again has continued analysis of the whole Sony DRM mess. They basically have taken a look at the ways of protecting an audio cd. Active protection (using software to prevent the duplication of music) is currently the main practical solution if you’re pursuing DRM. But what’s interesting is how much in common they have with spyware writers.

  • More details on Sober worm

    There’s a bit more detail in this betanews article on the sober worm. They basically say that the next expected “release” is January 8th, that f-secure has cracked the “code” of the worm.

  • More on Firefox 1.5 “vulnerability”

    I put vulnerability in quotes because it’s looking less like a problem. (Correct me if I’m wrong.) Here’s the situation. Both Sans and Mozilla have failed to duplicate the crash although have duplicated extremely slow browser performance. Here’s the official response from mozilla.org…

    We have investigated this issue and can find no basis for claims that variants of this denial-of-service attack can cause an exploitable crash, and no evidence for this claim has been offered. There does not appear to be any risk to users or their computers beyond the temporary unresponsiveness at startup.

  • Most home pc users lacking on PC security…

    Surprise!!… ummm wait, no… This article has come out while I’ve been in the midst of cleaning up a Windows ME pc that has been “0\/\/ned” (owned/controlled…) by someone other than the owner for a bit over 15 months. The system had NO antivirus, no firewall (no antispyware) and used dialup for internet. (That much said, this is probably the most infected dialup system I’ve seen… 30-100 virii, 230+spyware remnants/etc.) Anyway…. the article from cnet news claims that a recent survey found 81% of home pc users lacked either

    at least one of three types of critical security–a firewall, updated antivirus software or anti-spyware protection

  • Registrars not verifying contact information on domains?

    According to a GAO report one of the reasons that phishing and scam websites are because of a lack of enforcement and policing by registrars of accurate contact information. According to their study over 5% of sites had been registered with false data. ~2.5% had been registered with incomplete information. These findings come from a random sample of 300 domain names that they then did lookups on the domains.
