Ransomware world in 2021: who, how and why
In this report, we take a step back from the day-to-day ransomware news cycle and follow the ripples back into the heart of the ecosystem to understand how it is organized.
We track the ongoing activities of more than 900 advanced threat actors. Here we try to focus on what we consider to be the most interesting trends and developments of the last 12 months.
A newly discovered rootkit that we dub ‘Moriya’ is used by an unknown actor to deploy passive backdoors on public facing servers, facilitating the creation of a covert C&C communication channel through which they can be silently controlled. The victims are located in Africa, South and South-East Asia.
This report highlights significant events related to advanced persistent threat (APT) activity observed in Q1 2021. The summaries are based on our threat intelligence research and provide a representative snapshot of what we have published and discussed in greater detail in our private APT reports.
The investigation described in this article started with one such file which caught our attention due to the various improvements it brought to this well-known infection vector.
A41APT is a long-running campaign with activities detected from March 2019 to the end of December 2020. Most of the discovered malware families are fileless malware and they have not been seen before.
