  OVERVIEW

This is the Trend Micro detection for a hacking tool that can be used to launch a denial of service attack by exploiting the Remote Desktop Protocol Vulnerability (CVE-2012-0002).

This malware is a Proof-of-Concept (PoC) code for exploiting MS12-020. While the said Remote Desktop Protocol vulnerability could allow remote access to target machines, this PoC is only designed to perform denial of service (DoS) to a target machine through exploiting the vulnerability.

This hacking tool may be manually installed by a user.

  TECHNICAL DETAILS

Ports:

TCP port 3389 (MS WBT Server)

File Size:

279,040 bytes

File Type:

EXE

Memory Resident:

No

Initial Samples Received Date:

17 Mar 2012

Arrival Details

This hacking tool may be manually installed by a user.

NOTES:

This is the Trend Micro detection for a hacking tool that can be used to launch a denial of service attack by exploiting the Remote Desktop Protocol Vulnerability (CVE-2012-0002). When executed with no command-line parameters, the following message is displayed:

The first usage sends random data to a target machine. This can be used to test if the remote desktop service in the target machine is enabled. The parameter with -l specifies the size of data to send. The parameter -c causes the tool to pause for 5 seconds for every iteration. When the number of iterations is specified, this can function as a denial of service tool.

The second usage crashes the operating system.
