New tools attributed to the Russia-linked Gamaredon hacker group include a module for Microsoft Outlook that creates custom emails with malicious documents and sends them to a victim's contacts.
The threat actor disables protections for running macro scripts in Outlook and to plant the source file for the spearphishing attacks that spread malware to other victims.
Gamaredon has been in the cyber espionage game since at least 2013, targeting national security institutions in Ukraine for political and military gain. It became more active since December 2019.

A new package used by Gamaredon (Primitive Bear) in recent malicious campaigns contains a Visual Basic for Applications (VBA) project (.OTM file) that targets Microsoft Outlook email client with malicious macro scripts.
