Fed contractors aren’t using DMARC, new study finds

Just one of the 50 biggest federal IT contractors have adopted an important email security measure to guard against phishing, according to a new study. The Global Cyber Alliance’s (GCA) survey of the who’s who of Beltway contractors, including Lockheed Martin, Booz Allen Hamilton, and AT&T, found that all but one – analytics firm Engility, failed to use the Domain-based Message, Authentication, Reporting and Conformance (DMARC) protocol to block phishing attempts. Only one other contractor, the engineering firm and consultancy Tetra Tech, was implementing the second-highest DMARC control, in which phishing emails are quarantined.  Meanwhile, more than half the contractors had yet to implement any DMARC policy whatsoever, according to the study. Phishing is one of hackers’ favorite tools for breaching a network, and the federal government has been trying to defend against it for years. DMARC fights phishing by creating a public record for checking whether an email sender […]

It’s been more than a month since a mandatory Department of Homeland Security deadline passed for federal agencies to adopt security measures that stop attackers spoofing email — but more than a third have still failed to do so, according to an analysis of public records. What’s arguably worse is those that have implemented the measure called DMARC — Domain-based Message Authentication, Reporting and Conformance — have in many cases misconfigured it, meaning they remain exposed to spoofing. Federal IT specialists “aren’t picking up on the issue of subdomains,” explained Ian Breeze, a product manager at Easy Solutions, a vendor that provides software and advice to organizations seeking to implement DMARC, “They’re leaving their email subdomains open to fraud.” How DMARC works DMARC works by creating a public record that email systems can check to determine whether a message sender is in fact authorized to transmit on behalf of a […]

On a server I run, bogus incoming mail for a username which is my name. Should I be worried?

A server I run has a minimal public-facing mail exposure, running postfix on port 25 (no authentication on this port; IMAP is accessible by other means). In my mail logs it is not uncommon to find ‘bogus’ mail destined for no… Continue reading On a server I run, bogus incoming mail for a username which is my name. Should I be worried?
