Arrival Details

This Trojan arrives on a system as a file dropped by other malware or as a file downloaded unknowingly by users when visiting malicious sites.

NOTES:

A JavaScript may be written with malicious intent. Script malware makes use of Microsoft's Windows Scripting Host (WSH). WSH is a Windows administration tool that makes objects and services available for various scripts and provides a set of guidelines within which the script is executed. It allows remote malicious users to run scripts from the Windows desktop, Windows Explorer, and Windows command prompt.

WSH cannot distinguish between malicious and non-malicious script. Double-clicking on a script malware file will cause the malware to run its main action and payload, thus infecting the system.
