新版1004 phantom-token

请求头中包含phantom-token

定位到 window.signature

熟悉的vmp 和xhs一样

最新环境检测点

最新检测 canvas 下的 toDataURL方法较严

过程中 会用setAttribute给canvas 设置width height 从而使toDataURL返回不同的值

如果写死toDataURL的·返回值 就会被检测到

根据代码运行过程 实现不同的返回值

最后再加上 toString保护

可以发现明文 由#拼接 前后并加上3个随机字符

这里可以发现一些浏览器环境指纹
时间戳 location.href crypto.randomUUID
692c3b2c 是canvas的指纹
Screen.colorDepth
navigator.platform
availwidth
availHeight
等等
可以去对比和自己环境的不同
