Microsoft Teams Vulnerabilities Expose Users to Impersonation and Message Manipulation
Recent cybersecurity research has unveiled four critical vulnerabilities within Microsoft Teams, potentially allowing attackers to impersonate colleagues and manipulate messages without detection. These flaws, identified by Check Point researchers, could facilitate sophisticated social engineering attacks, undermining the platform’s integrity.
The vulnerabilities enable malicious actors to alter message content without triggering the Edited label, modify sender identities, and manipulate notifications to appear as if they originate from trusted sources. Such capabilities could deceive users into engaging with harmful links or divulging sensitive information.
Microsoft addressed some of these issues in August 2024 under CVE-2024-38197, with additional patches released in September 2024 and October 2025. Despite these updates, the findings highlight the necessity for continuous vigilance and prompt application of security patches to maintain digital trust within collaboration platforms.
