本文主要内容是关于对NSO的Pegasus间谍软件样本的分析。作者通过分析iTunes备份、崩溃日志和Telemetry数据,发现了一个可疑的.pkpass文件,该文件包含了一个大型的logo.png图片。通过进一步分析,作者发现该图片中隐藏了一个NSExpression,该表达式执行了一个payload。这个payload是一个复杂的NSExpression,它首先解码了Payload-CS,这是一个包含设备型号和构建号的plist文件。然后,它解码了Payload-C,这是一个另一个plist文件,其中包含了一个压缩的payload。最后,它解码了Payload-X,这是一个加密的payload。尽管作者成功解码了前三个payload,但Payload-X仍然是一个加密的payload,没有找到解密密钥。作者总结说,iOS取证调查是有效的,但需要更多的规模。iOS漏洞缓解措施被绕过,间谍软件供应商倾向于重用复杂的利用框架。
"NSExpression如何被执行?" "如何绕过NSExpression缓解措施?" "加密密钥在哪里?"
