How to Detect and Remove Netsky.P Worm?
What is the Netsky.P worm?

Netsky.P is a mass-mailing worm that uses its own SMTP engine to send itself to the email addresses it finds when scanning the hard drives and mapped drives. The worm also tries to spread through various file-sharing programs by copying itself into various shared folders.

The From line of the email is spoofed, and its Subject line and message body of the email vary. The attachment name varies with the .exe, .pif, .scr, or .zip file extension.

Also known as: WORM_Netsky.P, W32/Netsky.P@MM, W32/Netsky.P.worm, Win32.Netsky.P

How Does the Netsky.P Worm Infect My Computer?

When Netsky.P runs, it does the following:

  1. Creates a mutex "_-oO]xX|-S-k-y-N-e-t-|Xx[Oo-_" to allow only one instance of the worm to execute.

  2. Copies itself as %Windir%\FVProtect.exe.

  3. Drops the following file:


    Then, the worm loads and executes this file. It has a static MD5 hash value of 0x3018E99857F31A59E0777396AE634A8F.

  4. Creates the following files:
    • %Windir%\base64.tmp (40,520 bytes): MIME-encoded version of the executable
    • %Windir%\zip1.tmp (40,882 bytes): MIME-encoded version of the worm in a .zip archive
    • %Windir%\zip2.tmp (40,894 bytes): MIME-encoded version of the worm in a .zip archive
    • %Windir%\zip3.tmp (40,886 bytes): MIME-encoded version of the worm in a .zip archive
    • %Windir%\zipped.tmp (29,834 bytes): Worm in a .zip archive

  5. Adds the value:

    "Norton Antivirus AV"="%Windir%\FVProtect.exe"

    to the registry key:


    so that the worm runs when you start Windows.

  6. Deletes the values:
    • Explorer
    • system.
    • msgsvr32
    • winupd.exe
    • direct.exe
    • jijbl
    • service
    • Sentry

      from the registry key:


  7. Deletes the values:
    • system.
    • Video

      from the registry key:


  8. Deletes the values:
    • Explorer
    • au.exe
    • direct.exe
    • d3dupdate.exe
    • OLE
    • gouday.exe
    • rate.exe
    • Taskmon
    • Windows Services Host
    • sysmon.exe
    • srate.exe
    • ssate.exe
    • winupd.exe

      from the registry key:


  9. Deletes the following subkeys:
    • HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\CurrentVersion\
    • HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\WksPatch

  10. Scans the hard drive for folders that contain the following strings:
    • bear
    • donkey
    • download
    • ftp
    • htdocs
    • http
    • icq
    • kazaa
    • lime
    • morpheus
    • mule
    • my shared folder
    • shar
    • shared files
    • upload

      and copies the worm into that folder with the following file names:
    • "1001 Sex and more.rtf.exe"
    • "3D Studio Max 6 3dsmax.exe"
    • "ACDSee 10.exe"
    • "Adobe Photoshop 10 crack.exe"
    • "Adobe Photoshop 10 full.exe"
    • "Adobe Premiere 10.exe"
    • "Ahead Nero 8.exe"
    • "Altkins Diet.doc.exe"
    • "American Idol.doc.exe"
    • ......

  11. Retrieves the email addresses from the files on drives C through Z if the files have any of these file extensions:
    • .adb
    • .asp
    • .cgi
    • .dbx
    • .dhtm
    • .doc
    • .eml
    • .htm
    • .html
    • .jsp
    • .msg
    • .oft
    • .php
    • .pl
    • .rtf
    • .sht
    • .shtm
    • .tbb
    • .txt
    • .uin
    • .vbs
    • .wab
    • .wsh
    • .xml

  12. Uses its own SMTP engine to send itself to the email addresses it finds.

    The email subject, body, and attachment are constructed from many possible combinations. In an attempt to get the recipient to open the attachment, the subject and message may:
  • Suggest that the attachment is a detail message, photo, document, archive, report, bill, and so on.
  • Claim that the recipient's computer is infected and that the attachment is to be a scanner or an update from an antivirus publisher, including Symantec.
  • Warn the recipient that he/she has used an illegal Web site, software crack, or has sent spam.
  • Suggest that the attached zip file is password-protected. (This is not true for the samples that Security Response has seen to date.)

  13. The worm avoids sending to the email addresses that contain any of the following strings:

    • @antivi
    • @avp
    • @bitdefender
    • @fbi
    • @f-pro
    • @freeav
    • @f-secur
    • @kaspersky
    • @mcafee
    • @messagel
    • @microsof
    • @norman
    • @norton
    • @pandasof
    • @skynet
    • @sophos
    • @spam
    • @symantec
    • @viruslis
    • abuse@
    • noreply@
    • ntivir
    • reports@
    • spam@
