Are phishing emails evading your Proofpoint or other secure email gateways? The following are examples of phishing emails recently seen by the PDC in environments protected by SEGs.

TYPE: Credential Phish

Malicious emails continue to reach user inboxes, increasing the risk of account compromise, data breach, and ransomware attack. The same patterns and techniques are used week after week.
