More Information

W32/Nanpy-I is a worm for the Windows platform. It may spread to vunerable computers via the RPC-DCOM exploit, and attempt to redirect access to various banking websites.

The following patches for the operating system vulnerabilities exploited by W32/Nanpy-I can be obtained from the Microsoft website:

MS04-012

When first run W32/Nanpy-I copies itself to <System>\kkm.exe.

The following registry entry is created to run kkm.exe on startup:

HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Run
KKM Service
<System>\kkm.exe

HKCU\Software\Microsoft\Windows\CurrentVersion\Run
KKM Service
<System>\kkm.exe

The worm attempts to download and run an executable file from a remote URL.

W32/Nanpy-I may modify the HOSTS file, mapping the URLs of banking websites to a remote IP. At the time of writing, this IP address is not functional. Entries are added for:
