Malware type WORM
Spreading mechanism EMAIL
Summary None



This small email worm arrives normally as a zip archive, which it encourages you to open. Inside there is a small executable called spdtest.exe. If this executable is run, it will create two new files - one file called OneClock.vbs, and one file called script.ini, which is placed in the default MIRC directory, replacing any that already might be there.The OneClock.vbs file sends the SPDTEST.ZIP file to all users found in the Outlook address book.If, for any reason, the script does not find the ZIP archive, it will send itself instead. So, there is a possibility that only the VB script itself will propagate.The script.ini file will cause the popular IRC client mIRC to send the SPDTEST.ZIP to users joining the infected users channel.
