CISA orders federal agencies to catalog their networks, and scan for bugs

You always want to know what is attached to your network. And whether it could be vulnerable or not. In any organisation it’s normal for different devices, on- or off-prem, wired or wireless, to be constantly added or removed – and this can present an opportunity for malicious hackers to take advantage of improperly secured systems. In many cases, organizations have no idea about how many assets they have, let alone where they are all located.

Detecting the Manjusaka C2 framework

Security practitioners may know about common command-and-control (C2) frameworks, such as Cobalt Strike and Sliver, but fewer have likely heard of the so-called Chinese sibling framework “Manjusaka” (described by Talos in an excellent writeup). Like other C2 frameworks, we studied the Manjusaka implant/server network communications in our lab environment, and here we document some of the detection methods available. We have also open-sourced the content we describe.

Why You Should Avoid Public WiFi

The ability of a cybercriminal to place themselves between you and the connection point poses the biggest security vulnerability to public WiFi. You unknowingly communicate with the cybercriminal, who then collects and passes your information to the hotspot, rather than you connecting to the hotspot directly. While there are ways to stay protected on public WiFi, it is still advisable to avoid using it.
