    The virus onslaught continued late Tuesday as new versions of Bagle
    and MyDoom hit the Internet. The latest versions appeared to serve as
    digital graffiti, with the code delivering secret messages to the
    anonymous authors of other "competing" worms.
    
    According to analysis by security firm F-Secure Corp., the Bagle.J and
    MyDoom.G worms contain hidden messages aimed at the author of the
    NetSky worm.
    
    For example, Bagle.J includes the text: "Hey, NetSky, f**k off you
    b***h, don't ruine our bussiness, wanna start a war ?"
    
    MyDoom.G also attacked NetSky's author: "To netsky's creator(s): imho,
    skynet is a decentralized peer-to-peer neural network. we have seen
    P2P in Slapper in Sinit only. they may be called skynets, but not your
    sh**y app."
    
    Versions of NetSky spread rapidly across the Internet in February.
    
    F-Secure analysts said the MyDoom variant was functionally similar to
    the original MyDoom.A worm.
    
    The latest Bagle worm continued its social-engineering vector with a
    variable message aimed at corporate users, offering advice on e-mail
    account utilization. It comes as a pass-word-protected ZIP file with a
    Wordpad icon.
    
    One posting on the F-Secure Lab's Weblog suggested that Bagle is
    getting "more and more clever about the messages it sends. The latest
    variant can send widely variable mails, referencing the recipients'
    company or domain name directly."
    
    Earlier in the day, the Bagle.H worm struck. The newest version of the
    constantly morphing virus also arrived in a password-protected ZIP
    archive.
    
    Once executed, Bagle.H copies itself to folders for several popular
    peer-to-peer applications in an attempt to spread via shared files.
    
    Bagle.H, which is rated as a medium risk by the AVERT team at Network
    Associates Inc., also listens on TCP Port 2745 for instructions from
    remote hosts.
    
    The virus has an expiration date of March 25 and is spreading fairly
    quickly, experts said.
