    Well, it's very hard to say. It could be many things. You haven't given us enough information yet. For example, what is this exactly?

    What software firewall are you using, and exactly which page, tab or log from within that firewall are you reading that information from? You see, that quoted section there tells us nothing. It doesn't say if it blocked that traffic, or how much there was, or anything else. There must be a more detailed log somewhere in there than that.

    If you are now in a situation where you can't get to Google, I suspect somewhere in the midst of all this "attack activity" you may have told your software firewall to block this traffic. Now, everytime you go to Google, your own firewall is probably blocking you. But, even this is speculation on my part because we just don't have enough details.

    I think you need to undo whatever you've been doing in response to this attack. So far the data you have shown us is all Google related... Both the IP addresses (router and firewall) are Google owned, but were called "an attack" at some point even though it is highly doubtful it was anything like that.

    Now, you can't browse to Google. Well that makes sense. Something called an attack was reacted to - since it was Google and not an attack, blocking it means you can't get to Google.

    You're going to need to undo whatever it is in your firewall that responded to those Google packets as an attack, and tell it to allow Google again.

    I don't understand what you are saying there. Can you explain this more?

    Are you using a Linksys router with SPI?
    If so, those will just be late packets from a current connection that the SPI no longer considers valid (normal and nothing to worry about). Blocked unsolicited inbound traffic is recorded differently.

    How do you know they are trying to download an ActiveX control? What log is that from?

    More logs... We need detailed logs with all the relevant information or we can not advise you further.

    Well, you are mixing things together here, looking for a pattern. MS AS does not do firewall level blocking, so that is something else.

    Post the logs here for us to review.

    It is just the google home page trying to update the info on the page, It is not a hack attack. Having the home page as google allows the google server to know where you are on the web and it is just doing it's thing. I really wouldn't worry about it very much. I bet if you changed default home page the connections from google would probably stop or else really slow down.

    But Big C,

    These events shouldnt be coming through on my software firewall should they? Also the SSDP event is when anti-soyware reported a stopped download of active X. So you think know one is trying to hack me?

    I am really not sure what the activex was or where it was going but the info getting to your software firewall is coming through your router on the port that your browser has permission to use. I also use a linksys with the lan firewall and the only thing that ever gets through is info that is requested. Some of it is still stopped by the software firewall. as far as activex goes unless one of my security apps settings specifically blocks that one like the kill bits set by spywareblaster, they will reach my comp. With out knowing specifically what the active x was I am not sure I can suggest anything more for you to do. It may have been a legitimate app. i wish i knew more of what was going on.

    As mentioned earlier, these all appear to be releated to connections you have made. If these are logged dropped packets, they are likely just packets your software firewall considers no longer valid (shorter time-out). The router likely has a longer time-out before dropping late packets and that is why they are showing up in the software firewall logs.

    The log entry that references SSDP will not be directly related to the download of active x.
    This is related to another connection to google from your system. What indicates this is the source port 80. The 1900 was just the port being used by your system for the connection and also happens to be associated with SSDP. Some security software has the bad habit of associating common service names associated with ports in the logs which can be confusing as it may have nothing to do with it.

    These would only appear to be packets the firewall/router no longer considers a valid part of a connection you have made. They do not indicate anyone is trying to hack you.

    Edit: a sample from my router logs
    159572: May 29 2005 20:28:31.292 PDT:
    %FW-6-DROP_PKT: Dropping tcp pkt 64.91.226.241:80 => xx.xx.xx.xx:4198

    In this case the remote IP is the one for this forum, just a packet that is no longer considered part a current session (late), not that Wilders is trying to hack me ;)

    Regards,

    CrazyM
