(FireEye) FireEye detected the payload used in these attacks on August 23, 2013 in Japan. The payload was hosted on a server in Hong Kong (210.176.3.130) and was named “img20130823.jpg”. Although it had a .jpg file extension, it was not an image file. The file, when XORed with 0x95, was an executable (MD5: 8aba4b5184072f2a50cbc5ecfe326701).
Upon execution, 8aba4b5184072f2a50cbc5ecfe326701 writes “28542CC0.dll” (MD5: 46fd936bada07819f61ec3790cb08e19) to this location: C:\Documents and Settings\All Users\Application Data\28542CC0.dll
In order to maintain persistence, the original malware adds this registry key: HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Run\28542CC0 The registry key has this value: rundll32.exe “C:\Documents and Settings\All Users\Application Data\28542CC0.dll”,Launch
The malware (8aba4b5184072f2a50cbc5ecfe326701) then connects to a host in South Korea (180.150.228.102). This callback traffic is HTTP over port 443 (which is typically used for HTTPS encrypted traffic; however, the traffic is not HTTPS nor SSL encrypted).
