如果涉足H5或JS领域,你一定要了解JS保护!
如果你有网站、H5游戏产品、JS应用,你是否遇到过产品被复制、被修改、被攻击等问题?如果有,或者担心会发生。请看本文,本文所讲将帮你解决或避免这些问题。
首先,这里讲三个案例,本文将要解决的也将是这三种问题。
场景一:分析、曝光案例
锤子手机T1发布时,曾出过一件丑闻,在网络上被炒的沸沸扬扬。
其产品预约页面被发现数据造假,网页显示预约数量是真实数量的3倍。
该事件是被一名程序员发现并公布的,他只是简单的查看了网页源码,看到了JS代码中对数据量x3的逻辑。
很显然,网页中的JS代码未进行保护,否则锤子手机历史上不会有这条不光彩的新闻。
场景2:复制、盗用案例
H5应用A,
通过分析JS代码并加以简单修改,攻击者可轻松的复制、盗用,
快速的推出一款新产品:B。
场景3:篡改、攻击案例
商品销售页面A,
通过分析、调试得知产品价格由JS代码操控,
依据此,攻击者通过JS脚本修改产品价格,
修改后页面B中,正常475元的产品,可以用1元购买!
这几类案例每天都在发生,源源不断。
是时候使用专业的解决方案了。 http://www.jshaman.com/
萨满JS保护(JShaman):保护JS源代码、保护产品安全、保护版权!
JShaman解决方案:JS代码保护
JS产品安全隐患的根源在于:置于浏览器前端的JS代码,公开透明,任何人都可以查看、分析。因此,JS保护的核心是要让JS代码变的不可读、不可分析。
预览一个效果:
JShaman产品优势:更高安全性,多态变异!
为了进一步提高JS保护强度,
JShaman提供了名为多态变异的全球独创保护技术。
托管的代码每次被调用(引用、访问)代码自动变异。以此杜绝被跟踪调试。
JShaman保护技术:技术原理
对JS代码进行词法分析、语法分析,分离出变量、常量,并生成语法法。然后进行变量改名变形、常量阵列化加密、插入僵尸代码、平展控制流等技术操作,最后重新生成JS代码。此时即完成JS代码保护。此时的代码,与原始代码功能完全一致,但形式上已完全变样,不可读、不可分析、不可调试。
附录1:一段未保护的JS代码
用事实说话,看一段真实JS代码的保护效果
function myFunction(a,b){
return a * b;
}
document.getElementById("demo").innerHTML = myFunction(3,4);
代码功能逻辑一目了解,无安全性可言。
附录2:经JShaman保护后的安全JS代码
不可被分析、不可被修改、不可被篡改、不可被盗用、不可被攻击:

依据此,攻击者通过JS脚本修改产品价格,
修改后页面B中,正常475元的产品,可以用1元购买!
这三个案例的发生,根源都在于JS。案例一和二中,由于JS天生的客户端公开透明的特性,他人可以随意的阅读、分析其代码,并可以在其基础上任意修改、二次开发,造成了信息泄漏、被盗版的问题。如果代码是不可读、不可分析的呢?这种问题不会发生!
第三个案例,则是由于代码中存在BUG,而被攻击!如果代码被保护,不可读、不可修改则攻击事件也不会发生,针对于这一点可能有人会说:我的代码已经历了大量的使用测试、是安全的。那么谁可以保证版本迭代更新后每次都是安全无BUG的呢?这几类案例每天都在发生,源源不断。
是时候使用专业的解决方案了。 http://www.jshaman.com/
萨满JS保护(JShaman):保护JS源代码、保护产品安全、保护版权!
JShaman解决方案:JS代码保护
JS产品安全隐患的根源在于:置于浏览器前端的JS代码,公开透明,任何人都可以查看、分析。因此,JS保护的核心是要让JS代码变的不可读、不可分析。
预览一个效果:
JShaman产品优势:更高安全性,多态变异!
为了进一步提高JS保护强度,
JShaman提供了名为多态变异的全球独创保护技术。
托管的代码每次被调用(引用、访问)代码自动变异。以此杜绝被跟踪调试。
JShaman保护技术:技术原理
对JS代码进行词法分析、语法分析,分离出变量、常量,并生成语法法。然后进行变量改名变形、常量阵列化加密、插入僵尸代码、平展控制流等技术操作,最后重新生成JS代码。此时即完成JS代码保护。此时的代码,与原始代码功能完全一致,但形式上已完全变样,不可读、不可分析、不可调试。
附录1:一段未保护的JS代码
用事实说话,看一段真实JS代码的保护效果
function myFunction(a,b){
return a * b;
}
document.getElementById("demo").innerHTML = myFunction(3,4);
代码功能逻辑一目了解,无安全性可言。
附录2:经JShaman保护后的安全JS代码
不可被分析、不可被修改、不可被篡改、不可被盗用、不可被攻击:
