The Windows maker explained it truly is conscious of focused attacks in opposition to protection and govt entities in Europe and North The us that attempt to exploit CVE-2023-36884 by using specially-crafted Microsoft Office environment doc lures connected to the Ukrainian World Congress, echoing the most recent findings from BlackBerry.
“An attacker could create a specially crafted Microsoft Business doc that permits them to conduct remote code execution in the context of the sufferer,” Microsoft claimed. “On the other hand, an attacker would have to influence the target to open the malicious file.”
The business has flagged the intrusion marketing campaign to a Russian cybercriminal team it tracks as Storm-0978, which is also recognized by the names RomCom, Tropical Scorpius, UNC2596, and Void Rabisu.
