    Remote Administrator 2.x: highly possible remote hole or backdoor

    Hello!

    There is ongoing DDOS attack against some websites in Russia, including
    http://www.peterhost.ru. It has begun at 21, January, and has increased over
    time. Actual flood is performed by little executables on "infected"
    computers. These .exe files lie at the root directory of the drive C of each
    computer. They vary in size, and are, in common, from 3072 to 5120 bytes in
    size. Some of names of these executables are:

    666.exe
    rich.exe
    ric1.exe
    fich.exe
    tcpf.exe
    udpf.exe
    tzpf.exe
    tzpy.exe

    This in not a real infection, though. Affected computers have different
    versions of Windows installed. There are Windows 98 as well as Windows 2000
    and XP. Most of these computers are somewhat protected with firewall. Other
    software differs, too, but there is one common point between most of them:
    they have Remote Administrator 2.x (http://www.famatech.com) installed and
    reachable from the Internet.

    It does not look like a simple issue with weak passwords. I did speak with a
    owner of the affected PC, and he assured me that his RA password is strong
    enough. Moreover, there is a thread on the same problem:

    _start

    As of Feb, 12, most computers used for DDOS were located at IP networks with
    following first octets:

    200, 202, 203, 210-213, 217-220, 24, 61-69, 80-82.

    The password mentioned there was word "sharpest" (which is not Very Best
    choice, but...). The attacker was able to connect on second attempt (first
    after portscan, actually). There must be GREAT optimization of dictionary
    attack to achieve such result.
