100% of the phish seen by the Cofense Phishing Defense Center (PDC) have been found in environments protected by Secure Email Gateways (SEGs), were reported by humans, and analyzed and dispositioned by Cofense Triage.  

Cofense solutions enable organizations to identify, analyze and quarantine email threats in minutes.  

Are phishing emails evading your Proofpoint Secure Email Gateway? The following are examples of phishing emails recently seen by the PDC in environments protected by Proofpoint.

TYPE: Remcos RAT 

DESCRIPTION:  Finance-themed emails found in environments protected by Proofpoint and Microsoft Defender O365 deliver an attached malware downloader that downloads Amadey and runs Remcos RAT. 

TYPE: BazarBackdoor 

DESCRIPTION: Invoice-themed emails found in environments protected by Proofpoint, Microsoft Defender O365 and Symantec deliver BazarBackdoor via PDF attachments. The attached PDF redirects to a site that collects invoice order numbers. Once the order number is entered, it redirects to a payload URL that downloads an Office macro. The Office macro downloads and runs BazarBackdoor.

TYPE: Ava_Maria_Stealer 

DESCRIPTION: Notification-themed emails found in environments protected by Proofpoint deliver Ave_Maria stealer via embedded links. The embedded links download an Office macro that downloads an Ave_Maria executable.

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.
