Twitter Introduces DMARC to Prevent Phishing Emails

Twitter has introduced a technology called DMARC to help protect its users from phishing attacks and emails containing malicious malware.

The introduction of the DMARC is in response to the 110 million attack messages per day which are sent spoofing the Twitter domain name.

DMARC stands for ‘Domain-based Message Authentication, Reporting and Conformance’.  It builds on established protocols and is a standard for implementing the SPF (Sender Policy Framework) and DKIM (Domain Keys Identified Mail) email message validation and authentication systems.

DMARC is already supported by Google (Gmail); Microsoft (Outlook/Hotmail), Yahoo and AOL and is used by Facebook, PayPal and Amazon.

Twitter has seen a significant improvement since adopting the protocol, however the DMARC doesn’t prevent phishing that masquerade Twitters emails but don’t use the sender address.

Whilst the DMARC is an effective way to reduce the amount of attack emails it will not protect all users and the use of spam filtering is strongly advised.

In the workplace it is vital that spam filtering is used to protect all employees from spam emails containing malicious malware which could cause network failure.
