亲,单独运行的没错,但是不会报错。下载一下,百度网盘的;
如果你觉得看起来比较恶心,你自己换成字母好了,原理是一样的。

我试过改动,可以随便改动一下就出问题。
你的 dadadi.php 被你改动过了吧?

//function 在上面//定义了一个fun($var1,$var2='');大体意思是先先把$var1 base64还原 然后reutren ~取补数。再判断var2是否有值,下面那个好像没读懂 最后是 rerun aaa^bbb;(互斥)//下面加密了一串变量//放在一个数组中//数组的话,我后面的压缩包里面有个detempb可以弄出来,好像显示正确preg_match('正则表达式(我没有还原出来,还是还原错了感觉不对)',eval(gzuncompress(base64_decode(加密字符串穿))), ‘这里好像是一串数字’)

手工解密的方法就是看eval里的变量的值,可能出来的还是带eval的,要如此反复。反正是个体力活就对了。
哦?想当然了吧
第一遍出来就没有 eval 了

没想当然,我只是说可能,又没说这个代码第一遍解出来的一定有。说可能,只是因为我解过一个,要反复三四次才最后搞定。

这个我弄了一下,执行好像是经过二次@gzuncompress(base64_decode( code....... ))
第二遍eval 好像存在之前的数组中
但是到第二遍@gzuncompress(base64_decode( code....... ))执行后出现data error不知道您是怎么做的?能给个思路么?
他的结构比较复杂
第一层
Array( [?????] => plugin.class.php.php [?????] => strlen [?????] => empty [?????] => base64_decode [?????] => str_pad [?????] => eval [?????] => preg_replace [?????] => /47183fe0e6a80ab66633459f55a88a71/e)

[?????] => explode [?????] => in_array [?????] => gethostbyname)第三层又直接使用了 eval

preg_replace('\b777fb918ffda23fb0979c4ca77ab814\e',eval(gzuncompress(base64_decode($code))),'??b777fb918ffda23fb0979c4ca77ab814???');
代码是这样的
应该是思路有点问题,做不下去了
$filename = __DIR__ . '/plugin.class.php';$gl = '';$old_vars = '';$c = explode('eval', file_get_contents($filename));file_put_contents($filename.'_0.php', $c[0]);$old_vars = get_defined_vars();include $filename.'_0.php';$new_vars = array_diff_key(get_defined_vars(), $old_vars);//print_r($new_vars);$gl = key($new_vars);$ev = array_search('eval', $$gl);${$gl}[$ev] = '$code';$code = create_function('$s', <<< CODEglobal \$$gl;echo \$s,PHP_EOL;eval(explode('@', \$s)[0]);file_put_contents('t_2.php', '调整了一下思路,应该是解开了
$filename = __DIR__ . '/plugin.class.php';function code($s) { $v = $GLOBALS['gl']; $$v =& $GLOBALS[$v]; echo $s . PHP_EOL; $s = str_replace('eval(', 'code(', $s); eval($s);}$gl = '';$old_vars = '';$c = explode('eval', file_get_contents($filename));file_put_contents($filename.'_0.php', $c[0]);$old_vars = get_defined_vars();include $filename.'_0.php';$new_vars = array_diff_key(get_defined_vars(), $old_vars);$gl = key($new_vars);$ev = array_search('eval', $$gl);${$gl}[$ev] = 'code';file_put_contents($filename.'_1.php', '输出的最后一行就是最后执行的代码
