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 ...

I recently set out to become more acquainted with Maltego, a useful program for open-source intelligence (OSINT) and forensics, developed by Paterva. I also noticed there is an ongoing campaign against Turkey using Android banking Trojans such as Anubis and Cerberus. Both are Malware-as-a-Service offerings that supply a builder and mobile remote access Trojan (MRAT) to steal credentials from Android users. Security researchers such as @MalwareHunterTeam, @ReBensk, @pr3wtd, and @mertcangokgoz, and others have all recently shared new samples of Cerberus and Anubis targeting users in Turkey with mobile data “gifts” that are offered from their mobile carriers due to COVID-19. Various websites are registered hosting links to fake apps, which were downloaded from the threat actor’s GitLab or BitBucket repositories. These apps are Android packages (.APK) that can be distributed via SMS, instant messaging app, on Twitter, via email, and other social engineering techniques. With the ...
