Security news from bleeping computer. Be careful of Zoom invites..:
A phishing campaign targeting users of Outlook Web Access and Office 365 services collected thousands of credentials relying on trusted domains such as SendGrid.
The threat actor behind this activity, which received the name “Compact,” has been operating since at least the beginning of 2020 and likely collected more than 400,000 credentials in multiple campaigns.
