Highly deceptive attack that exploits inherent trust in Microsoft’s cloud services.
Microsoft 365 infrastructure has been leveraged in new business email compromise campaigns seeking to enable credentials compromise and account takeover intrusions.
According to a report by Guardz, threat actors have been using legitimate Microsoft domains to deliver malicious emails that integrate Microsoft's logos, display name fields, and organisational metadata to spread malware.
“The result is a highly deceptive attack that exploits inherent trust in Microsoft’s cloud services, making it significantly more challenging for security teams to detect and mitigate," said Guardz researchers.
