Our analysis of => Sept 28. Attack of the Day. Exploit/MSWordAgent!IK Townhall Magazine... from spoofed xxxx@heritage.org

" The exploit works on office 2003. Tested on XP SP2-3. The exe is embedded at OFFSET=0x4c00 with key 0x25. The Word document attached is at offset 0x7400 with key 0x25. The shellcode in the exploit drops a binary with name "svchost.exe" and a doc file in %temp% folder. The shellcode in the xls decodes the exe and drops it. The binary and Doc are XOR'ed with key 0x25 except bytes 0x25, 0x00, 0xFF and 0xDA". to be continued..
