APT Activity Monitor / keylogger

Here is a small piece of APT type malware, which records all user activities and keystrokes, including passwords. The attacker needs to execute it and it will create a hidden folder in the same directory named mssvr and a text log file called Updaterinfo.dat. The log can be sent or downloaded later using other means (look for a file named send1.exe, for example  - never mind, send1.exe does not appear to have any sending abilities). There are usually many other files associated with the attack - backdoors, misc installers, command interpreters, etc.  The Anubis report is brief and clear - see it posted below in full. The binary and mssvr folder can be anywhere, in some temp folder, for example.
 
mssvr 
mssvr\UpdaterInfo.dat ]

Fixed the archive, re-download it if you could not open it before
Download  dc281590aa9153000e983622f0559ea1 Adobeinfo.exe  ac as a password protected archive (please contact me for the password if you need it)
Two name variants known (but there can be an endless list) are Adobeinfo.exe and lognoreg.exe.
