僵尸网络控制着可能使用被感染主机来识别潜在的目标。下面是该公司的蜜罐捕获到的一个RFI(远程文件包含)攻击代码里的片段: - sub google() { my @list; my $key = $_[0]; for (my $i=0; $i<=400; $i+=10){ my $search = ("http://www.google.com/search?q=".&key($key)."&num=100&filter=0&start=".$i); my $res = &search_engine_query($search); while ($res =~ m/<a href="\"?http:\/\/([^">\"]*)\//g) { if ($1 !~ /google/){ my $link = $1; my @grep = &links($link); push(@list,@grep); } } } return @list;8 V' ?$ a! v5 b. \* H!
