In the next step of the video, we will analyze in more details the incident and the impact it had on Analytical Center for the Government of the Russian Federation and their customers.
On 28 January 2026, a cybersecurity incident called "APT28 Exploits Zero-Click Microsoft Office Flaw in European Espionage Campaign" came to light.
In late January 2026, Russian state-backed hacking group APT28 (Fancy Bear) launched a targeted cyberespionage campaign against government and military organizations in Poland, Greece, and Ukraine, focusing on maritime and transport agencies.
The disruption is felt across the environment, affecting Microsoft Office and Microsoft Outlook, and exposing Government and military communications, sensitive documents.
In response, and began remediation that includes Patch CVE-2026-21509, monitor for unusual filen.io traffic or NotDoor-related Outlook rules.
The case underscores how teams are taking away lessons such as The campaign underscored APT28’s ability to blend malicious activity with legitimate traffic, complicating detection. Organizations must prioritize patching zero-day vulnerabilities and monitoring for unusual traffic patterns, and recommending next steps like Patch CVE-2026-21509 immediately, Monitor for unusual filen.io traffic and Check for NotDoor-related Outlook rules.
Finally, we try to match the incident with the MITRE ATT&CK framework to see if there is any correlation between the incident and the MITRE ATT&CK framework.
The MITRE ATT&CK framework is a knowledge base of techniques and sub-techniques that are used to describe the tactics and procedures of cyber adversaries. It is a powerful tool for understanding the threat landscape and for developing effective defense strategies.
