Impersonated Evite and Punchbowl invitations used for credential phishing and malware distribution

Sublime's Attack Spotlight series aims to educate readers about the email threat landscape through real-world examples of attacks, detailing adversary tactics and techniques, and explaining detection methods. It highlights a surge in malicious digital invitation-based attacks, particularly impersonating brands like Evite and Punchbowl, which utilize tactics such as credential phishing and malware distribution. These attacks often involve sophisticated brand impersonation, with payloads varying across attack types, and are typically distributed to undisclosed recipient lists. The series discusses specific examples, such as a Google-specific credential phishing attack using Cloudflare-hosted pages and Remote Monitoring and Management (RMM) malware attacks. It underscores the importance of adaptive email security platforms that use AI and machine learning to detect these threats by identifying discrepancies such as brand impersonation and suspicious domains. The series encourages readers to stay informed by subscribing to Sublime's newsletter and checking their blog for regular updates on new attack patterns and security strategies.
