Technical Details

Dluca components can be hiddenly dropped and activated on a computer when Internet Explorer is used to browse certain pages on Internet.

When activated, Dluca connects to certain websites, downloads and activates additional components (executable files) and reports certain info about a computer where it is installed to a website.

The later Trojan-Downloader:W32/Dluca.T variant silently installs itself to system. It copies itself as files, with the names infwin.exe and infwin-uninstall.exe, to the Windows System folder and adds a startup key for the infwin.exe file into the System Registry. The trojan-downloader then deletes the file it was started from.
