Recent spikes in traffic on this port are most likely caused by the Dabber worm, which spreads itself by connecting to the Sasser FTP server (port 5554) and exploiting a buffer overflow vulnerability in the FTP server.

Used by sasser worm to spread itself. Sasser spreads by scanning IP addresses for access via TCP Port 445 looking for vulnerable systems, according to Symantec. When it finds an unpatched Windows XP or Windows 2000 computer, Sasser.A adds the file "avserve2.exe"="%Windir%avserve2.exe" in the registry, tries to block attempts to shut down or reboot the infected computer (by using the AbortSystemShutdown application programming interface) and then begins scanning other systems via an FTP server on TCP Port 5554 seeking to spread itself,
