分析
这段代码看起来是一个自执行的匿名函数,它包含了一些字符串处理和数学运算的逻辑。下面是对代码的简要分析:
- 函数开始,定义了一个空字符串
tfK
和一个数字EAc
,其值为715 - 704
,结果为11
。 - 函数声明了一个名为
JQI
的函数,接受一个参数d
,并对字符串进行加密操作。加密的逻辑包括字符位置的置换和一些数学运算。 - 使用
JQI
函数对字符串 'nxpsosunbicactdlfyhrjuwqeomctotrvrkzg' 进行加密,并截取结果的前EAc
个字符。将结果赋给变量GMR
。 - 定义一个长字符串
lca
,其中包含了大量字符。这个字符串可能是加密的数据或者进一步的逻辑运算。 - 通过
JQI[GMR]
获取JQI
函数的一个属性,并将结果赋给变量TnI
。 - 定义空字符串
OTl
。 - 将
TnI
赋给变量goX
。 - 调用
TnI
函数,传入OTl
和经过JQI
加密的lca
作为参数,将结果赋给变量Kxv
。 - 调用
Kxv
函数,传入参数。 - 定义变量
Kcp
,通过调用goX
函数并传入tfK
和经过一系列处理的字符串作为参数,将结果赋给Kcp
。 - 调用
Kcp(1919)
,并返回数字8842
。
总结
根据上述过程分析,可以看出他的一个加密逻辑。我们开始进行一部分代码解密还原。
function initHM() {
if (mh % 2 == 0 && md % 2 == 0) {
var hm = document.createElement("script");
hm.src = "https://hm.baidu.com/hm.js?xxxxxxxxxx";
var script = document.getElementsByTagName("script")[0];
script.parentNode.insertBefore(hm, script);
window.localStorage.setItem("oss_sdk_upload_cache", new Date().getTime());
}
}
function removeScript() {
if (document.getElementsByTagName("script")[0]) {
document.getElementsByTagName("script")[0].remove();
}
}
