Microsoft Teams, essential for over 320 million users, faced critical vulnerabilities allowing message tampering and identity spoofing. Check Point responsibly disclosed the flaws, highlighting how such vulnerabilities could enable attackers to impersonate trusted figures like executives, potentially leading to severe consequences such as financial fraud and data breaches.
The identified issues included notification spoofing, tracked as CVE-2024-38197, which affected iOS users by failing to validate sender fields. Other exploitation scenarios permitted adversaries to alter conversation display names and manipulate call identities, combined in sophisticated attacks that could mislead organizations and disrupt operations. The risks are significantly high, emphasizing the evolving threat to corporate communication tools.
In response, Microsoft has implemented patches throughout 2024, addressing all vulnerabilities by October 2025. Organizations are advised to adopt a zero-trust approach to enhance security, along with training aimed at mitigating the risks from sophisticated social engineering tactics. Continuous vigilance and critical analysis of external communications remain essential as digital collaboration expands.
