Blocking Impersonation, Phishing and Malware Attacks with DMARC
Combine DMARC Analyzer’s email channel visibility and reporting with Mimecast DMARC enforcement and Targeted Threat Protection.
Email impersonation attacks, or email fraud, continues to grow, with Mimecast’s latest Email Security Risk Assessment pointing to a 22% increase over the previous quarter. Detecting and stopping these increasingly-sophisticated social engineering attacks needs a multi-layered approach.
Impersonation attacks aim to trick employees into taking action like transferring money or divulging sensitive information. They do this by making it look like the request has come from someone they know and trust – like a CEO or CFO for example.
Types of Impersonation Attacks
- Lookalike domains
- Display name spoofing
- Newly registered domains
- Reply-to mismatch
- Social engineering language in the subject / body of any email
- Owned domains (unauthorized)
The last item above, the illegitimate use of an organizations owned domains, where using Domain-based Message Authentication, Reporting & Conformance (DMARC) authentication is the best defensive strategy. It works by preventing anyone except for specifically authorized senders to send mail using an organizations domain. There are third-party senders like CRM and marketing automation systems that need to send mail and these can be authorized while others are blocked, or rejected.
Mimecast and DMARC Analyzer for Increased Attack Protection
Mimecast’s gateway and Targeted Threat Protection – Impersonation Protect service combines multiple indicators of compromise to stop attacks using most of the tactics listed, from targeting employees. Where DMARC Analyzer comes in, is to prevent the unauthorized use of an organizations own domain(s) to attack their customers, suppliers, other external parties and even their own employees.
