|What's been found||Severity Level|
|Replication across networks by exploiting weakly restricted shares (common for Randex family of worms).|
|Contains characteristics of Conficker/Downadup/Kido, a worm that spreads by exploiting the Microsoft Windows Server Service RPC Handling Remote Code Execution Vulnerability.|
|Capability to block security-related software by modifying firewall settings and by disabling security services, such as Windows Update, Norton Autoprotect, Kaspersky Anti-Virus, etc.|
|Can possibly obtain IP address (of the compromised computer) by connecting to several specific URLs.|
|Can potentially create the file autorun.inf on any accessible mapped drive so that it executes whenever the drive is accessed.|
|Downloads/requests other files from Internet.|
|Contains characteristics of an identified security risk.|
|Possible Security Risk|
- Attention! The following threat category was identified:
||A network-aware worm that attempts to replicate across the existing network(s)
- There was a new process created in the system:
|Process Name||Process Filename||Main Module Size|
|[generic host process]||[generic host process filename]||20,480 bytes|
- [generic host process filename] is a full path filename of [generic host process].
- The following system services were modified:
|Service Name||Display Name||New Status||Service Filename|
|ERSvc||Error Reporting Service||"Stopped"||%System%\svchost.exe -k netsvcs|
|wscsvc||Security Center||"Stopped"||%System%\svchost.exe -k netsvcs|
|wuauserv||Automatic Updates||"Stopped"||%System%\svchost.exe -k netsvcs|
- %System% is a variable that refers to the System folder. By default, this is C:\Windows\System (Windows 95/98/Me), C:\Winnt\System32 (Windows NT/2000), or C:\Windows\System32 (Windows XP).
- To mark the presence in the system, the following Mutex objects were created:
- The following Host Names were requested from a host database:
- The data identified by the following URLs was then requested from the remote web server:
- Heuristically identified capability of spreading across the following weakly restricted network shares:
- The network replication uses a dictionary attack by probing credentials from the following list:
