Why everybody should use DMARC to prevent phishing

By | September 8th, 2016|Categories: Blog|Tags: , |

Email is a major source of phishing and malware attacks. The Locky ransomware solely contributed to a 412% increase of malware emails in March compared to February, according to CYREN’s May 2016 cyberthreat report. While I believe that awareness and training is the most universally effective counter-measure, even that is really difficult, according to this recent study. We probably need a combination of training and technological advancements. One of the latter has to do with email authenticity. Can you trust an email’s sender adress?

In this blog I’ll describe the current state of spam classification, and propose a pretty innovative method that can significantly improve both senders’ and recipients’ satisfaction (as well as reducing the burden on administrators and support staff) by enabling senders to report false positives if they pass a CAPTCHA test. Let’s start by familiarising ourselves with the history of anti-spam. […]

Google's recent announcement that they'll be adding encryption (TLS) and authentication (DKIM/DMARC) status icons to Gmail is a great initiative. What they do In addition to being displayed for received email, the encryption indicator works when composing email as well. It's however not updated in realtime, and seems to be cached per domain.

By | December 7th, 2015|Categories: Blog|Tags: |

Photo by David Drexler At the center of the Halon SMTP platform is our domain-specific scripting language. As our users are well aware, the syntax is inspired by languages such as PHP (e.g. $variable) and Python (e.g. slices [0:10]).
