原文:https://engineering.salesforce.com/tls-fingerprinting-with-ja3-and-ja3s-247362855967 摘要 在这篇文章中,我们将为读者介绍如何使用JA3和JA3来提取和识别客户端和服务器之间的TLS协商的指纹。这种组合型的指纹识别技术,能够为特定客户端与其服务器之间的加密通信提供具有更高的识别度。例如: ...
TLS 握手指纹又叫 SSL 指纹,或者 JA3 指纹,是根据客户端向服务端发送的 Client Hello 信息中部分字段计算得出的 hash 值信息。 此外,在 TLS 握手中还有服务端响应的 Server Hello,这类信息也有特征,根据类似的思路可以得到 JA3S 指纹。又由于服务端会根据不同的 Client Hello 响应不同的 Server Hello,根据这个...

The authors insist that JA3 is not sufficient for mobile app identifications; however, a combination of JA3, JA3S, and SNI can improve reliability. Note that Kotzias et al. [105] reported 7.3% fingerprint collision in their longitudinal passive dataset while applying a client fingerprinting ...
