Our previous report on Cobalt Strike focused on the most frequently used capabilities that we had observed. In this report, we will focus on the network traffic it produced, and provide some easy wins defenders can be on the look out for to detect beaconing activity. We cover topics such as domain fronting, SOCKS proxy, C2 traffic, Sigma rules, JARM, JA3/S, RITA & more. As with our previous articl
TL;DR JARM is an active Transport Layer Security (TLS) server fingerprinting tool. Scanning with JARM provides the ability to identify and group malicious servers on the Internet. JARM is available here: https://github.com/salesforce/jarm JARM fingerprints can be used to: Quickly verify that all servers in a group have the same TLS configuration.Group disparate servers on the internet by configura
Please read the initial JARM blog post for more information. JARM is an active Transport Layer Security (TLS) server fingerprinting tool. JARM fingerprints can be used to: Quickly verify that all servers in a group have the same TLS configuration. Group disparate servers on the internet by configuration, identifying that a server may belong to Google vs. Salesforce vs. Apple, for example. Identify
Grabbing a banner is the first and apparently the most important phase in both the offensive and defensive penetration testing environments. In this article, weâll take a tour to âBanner Grabbingâ and learn how the different command-line tools and web interfaces help us to grab the banner of a webserver and its running services. Table of Content Introduction Why Banner Grabbing? Types of Banner Gr
The Transport Layer Security (TLS) is an internet protocol to protect data when transmitted. It is the "S" in HTTPS but can be used for more than just websites, like secure file transfer or by encrypted e-mail transmission. Initially it was known as SSL but was actually renamed TLS over twenty years ago. Getting TLS right is not easy. Expired certificates, outdated SSL versions, unpatched vulnerab
