    I have seen those packets, except the DF and MF flags were both set
    and BTW you can recreate those packets by using Microsoft ping with
    the following command:
    ping -l 1500 (or what ever size you see). Just my .02 worth


    The third type of traffic from the attacking machine consisted of
    large ICMP echo-request packets, all going to the same destination IP
    address. The ICMP packet contents consisted entirely of the lowercase
    letters 'a' through 'w' repeated many times, e.g.,


    Anyway, this may mean that some type of WebDAV data-gathering or
    exploit capability has been incorporated into a software package that
    also compromises machines via SMB. There wasn't direct evidence that
    the software package was associated with planned exploitation of the
    CA-2003-09 vulnerability via WebDAV, although it may have been. The
    ICMP traffic suggests that the software package may have a DoS
    capability that's separate from the SMB and WebDAV traffic.
