Sober.O@mm

Spreading

When the worm is first executed, it copies itself to a subfolder under the Windows folder, and starts to scan text files for email addresses. These addresses are then used as both sender and recipients for later infected mails. At the same time, the worm shows an error message on the screen : "Error: CRC not complete"
Emalis sent will have German or English text depending on the recipient address.
