Abstract
Malware fingerprinting on encrypted Transport Layer Security (TLS) traffic. A method may include obtaining, by the computing device, input data of a TLS communication between a client device and a server device; extracting, by the computing device, features associated with the TLS communication; determining, by the computing device, an association between the TLS communication and a known malware family by applying a clustering algorithm to the extracted features; analyzing, by the computing device, at least one cluster determined by applying the clustering algorithm to determine a purity level; assigning, by the computing device, a malware family fingerprint to the TLS communication based on the purity level; applying, by the computing device, the malware family fingerprint to a backend of a network to determine a probability of an attack; and initiating, by the computing device, a security action based on the probability of the attack.
