Rewterz Threat Alert – BlackCat Ransomware – Active IOCs

April 26, 2022

Severity

High

Analysis Summary

BlackCat – aka AlphaVM & AlphaV – is a Ransomware family that is deployed as a part of a Ransomware as a Service (RaaS). It is written in the Rust programming language and can run on Windows, Linux-based operating systems (Debian, Ubuntu, ReadyNAS, Synology), and VMWare ESXi.
This ransomware first appeared in November 2021. The majority of the group’s victims have been in the United States, although BlackCat and its associates have also targeted organizations in Europe, the Philippines, and other regions. Construction and engineering, retail, transportation, commercial services, insurance, machinery, professional services, telecommunication, auto components, and medicines are among the targeted sectors of BlackCat ransomware.
This ransomware can be set to encrypt files using either the AES or ChaCha20 algorithms. It can destroy volume shadow copies, terminate programs and services, and stop virtual machines on ESXi servers to maximize the quantity of ransomed data.

Recently, the Federal Bureau of Investigation (FBI) of the United States published a flash report stating that BlackCat ransomware had compromised at least 60 organizations globally since its inception in November.
