这个过程叫做反混淆(Deobfuscation)。 麻烦,着实麻烦。就没有省事儿点的办法吗? 让AI来啊! 最近,Facebook就出了这样一个语言模型DOBF,专治代码混淆。
In this paper, we first evaluate the performance of our subtree-based deobfuscation, which is divided Third, we evaluate the efficiency of deobfuscation by calculating the average time required to deobfuscate Next, we evaluate the benefit of our deobfuscation method on PowerShell attack detection.

图片代码混淆(obfuscation)和代码反混淆(deobfuscation)在爬虫、逆向当中可以说是非常常见的情况了,初学者经常问一个问题,类似 _0x4c9738 的变量名怎么还原? 参考资料Predicting Program Properties from “Big Code”Statistical Deobfuscation of Android ApplicationsRecovering
反混淆(deobfuscation)指的是从混淆的代码中恢复其原始、可读的形式的过程。

smali_code = smali_code.replace(old_var, new_var) return smali_code # 应用反混淆 def apply_deobfuscation
good luck with deobfuscation// the easy way or the hard way? which one will you take?
与此同时,反混淆(Deobfuscation)技术也在不断发展,作为逆向工程的重要组成部分,它旨在恢复被混淆的代码,使其恢复可读性和可分析性。
