[stalk:00889] WEB-IIS multiple decode attempt





はぎやまです。

Tue Sep 18 22:13:44 2001 頃から Tue Sep 18 23:13:20 2001 まで
の間に、5つのホストから WEB-IIS multiple decode attempt を受け
ています。

例えば
[Tue Sep 18 23:13:01 2001] [error] [client 61.xx.xx.xxx] File does not exist: /h
ome/httpd/html/scripts/root.exe
[Tue Sep 18 23:13:02 2001] [error] [client 61.xx.xx.xxx] File does not exist: /h
ome/httpd/html/MSADC/root.exe
[Tue Sep 18 23:13:05 2001] [error] [client 61.xx.xx.xxx] File does not exist: /h
ome/httpd/html/c/winnt/system32/cmd.exe
[Tue Sep 18 23:13:06 2001] [error] [client 61.xx.xx.xxx] File does not exist: /h
ome/httpd/html/d/winnt/system32/cmd.exe
[Tue Sep 18 23:13:06 2001] [error] [client 61.xx.xx.xxx] File does not exist: /h
ome/httpd/html/scripts/..%5c../winnt/system32/cmd.exe
[Tue Sep 18 23:13:13 2001] [error] [client 61.xx.xx.xxx] File does not exist: /h
ome/httpd/html/_vti_bin/..%5c../..%5c../..%5c../winnt/system32/cmd.exe
[Tue Sep 18 23:13:13 2001] [error] [client 61.xx.xx.xxx] File does not exist: /h
ome/httpd/html/_mem_bin/..%5c../..%5c../..%5c../winnt/system32/cmd.exe
[Tue Sep 18 23:13:14 2001] [error] [client 61.xx.xx.xxx] File does not exist: /h
ome/httpd/html/msadc/..%5c../..%5c../..%5c/..<C1>^\../..<C1>^\../..<C1>^\../winn
t/system32/cmd.exe
こんな感じです。

未だ詳細については調査中ですが、どのホストも同じような攻撃コード
を送っているようです。
