Introduction to Infrastructure Pivoting Pivoting on infrastructure is a handy skill for cyber threat intelligence (CTI) analysts to learn. It can help to reveal the bigger picture when it comes to malware, phishing, or network exploitation campaigns. Infrastructure pivoting essentially is the act of looking for more systems an adversary has created. The main benefit of this pursuit is the identification of additional targets or victims, more tools or malware samples, and ultimately new insights about the adversary’s capabilities. If done correctly, being able to pivot on adversary infrastructure will be very useful during incident response (IR) engagements. For example, it may lead to being able to attribute the intrusion to a known adversary. This will help others during an IR engagement understand the level of threat posed to the victim organisation. Receiving Threat Data To be able to pivot on adversary infrastructure, threat data is needed such as the intelligence shared ...

And by 'analysing things in the wild' I mean looking for live reports of cybercriminal activity by others online. One of my favourite examples is SMS phishing text messages, also called Smishing scams.  It is a commonly held view that new analysts learn best by doing. It also does not matter if you are not the first to report on something. New analysts should not worry about that, as long as they do a bit of OSINT at least to confirm they do not accidentally say they are the first and only researcher to find whatever it is they found.  In my experience, there are always organizations and teams with more experience and telemetry than you. It's just that they did not report on it publicly (yet). This goes for even the top research teams at incident response or antivirus companies. Not "be...
