À propos de cet audio
The provided sources collectively address the escalating threat of phishing attacks targeting Microsoft 365 users, specifically highlighting the exploitation of link wrapping services like Proofpoint and Intermedia to bypass traditional security measures. These malicious campaigns leverage techniques such as URL manipulation and social engineering to trick users into granting unauthorized access or revealing credentials, often through fake login pages for Microsoft Office 365 or Microsoft Teams. The texts also detail how Microsoft Defender for Office 365 offers advanced protection, including Safe Links and Safe Attachments, and provides administrators with simulation training tools to educate users and test an organization's defenses against these evolving identity-based attacks. Furthermore, they emphasize the critical need for multi-factor authentication (MFA) and robust incident response playbooks to mitigate risks and remediate compromised accounts.
