APT28 activities later continuing their operation in 2017 and 2018 with more sophisticated attacks with the ultimate motivation of intelligence gathering and targeting different organization.
- A well-known international organization
- Military targets in Europe

This group actively attack using a malware called Sofacy for various targets which contain two primary component,
- . Trojan.Sofacy – Basic reconnaissance on an infected computer and drop another malware.
- Backdoor.SofacyX – It is another malware using to steal the data from the infected computer.

Link with Earworm Espionage Operations
Researchers believe that APT28 might have a link with another cybercrime group called Earworm (aka Zebrocy).
Earworm actively attacking since 2016 and perform intelligence gathering operations against military targets in Europe, Central Asia, and Eastern Asia.
They are using two different following malware component to infiltrate the target network,
- Trojan.Zekapab – capable of carrying out basic reconnaissance functions and downloading additional malware
