Kaspersky Lab reports the detection of the network worm Duload, which is spreading across the KaZaA file-exchange network. Presently Kaspersky Lab has already received several registered instances of infection in Italy. The worm itself is a Windows (PE EXE) application written in Visual Basic. Currently two modifications of the Duload worm are known, each having a different file size:
  • Worm.P2P.Duload.a - 18432 bytes
  • Worm.P2P.Duload.b - 7680 bytes (Compressed with the UPX utility) If the infected attachment is accidentally opened "Duload" copies itself to the Windows system directory under the name "SystemConfig.exe" and modifies the system registry so that this file automatically loads each time Windows is started. Next, the Duload worm creates a folder in the Windows directory called "Media" and copies itself to this directory under 39 different names. Such as:
    • Pamela Anderson And Tommy Lee Home Video.exe
    • Alicia Silverstone Payboy Nude.exe
    • Kama Sutra Tetris.exe
    • Soldier Of Fortune 2 Mutiplayer Serial Hack.exe
    • The Sims Game Crack.exe
    • Warcraft 3 Battle.net Crack.exe "Duload" then once again modifies the system registry in order to make the "Media" folder accessible to all other KaZaA network users. One modification of the worm (Worm.P2P.Duload.a) also downloads from an Internet site several Trojan programs designed to establish the unauthorized remote management of victim computers. The defense against "Duload" has already been added to the Kaspersky Lab Anti-virus database. More detailed information regarding the Duload network worm can be found in the Kaspersky Lab Virus Encyclopedia.
