Ransomware Campaigns Target Microsoft Teams Users

/ 1 min read

💬🔓 Ransomware campaigns increasingly target Microsoft Teams for infiltration. Cybersecurity researchers have identified two ransomware groups, STAC5143 and STAC5777, exploiting Microsoft Teams’ settings that allow external users to initiate chats and meetings with internal users. These attackers employ social engineering tactics, phishing attempts, and vulnerabilities in communication protocols to gain unauthorized access. Successful attacks can lead to data encryption, operational disruptions, and significant financial losses. To mitigate these risks, businesses are advised to implement robust authentication protocols, conduct regular security training, and utilize advanced threat protection features. Proactive monitoring and vulnerability intelligence are essential for maintaining a secure collaborative environment on Microsoft Teams.
