⚠ IP Confounder Detected: Microsoft 365 Exchange Online Protection (EOP)
Exchange Online Protection (EOP) is a cloud-based email filtering service included with all Microsoft 365 subscriptions to protect against spam, malware, and phishing attacks. It automatically secures mailboxes by filtering incoming and outgoing messages in real-time using anti-spam, anti-malware, and content filters. During periods of active campaign activity, these can largely be ignored (esp. when recipients are on Exchange). However, forged emails have been observed from Microsoft infrastructure that have this signature too.
