MX Logic Filters Attachment-Based Spam

MX Logic adds a new layer to its security filtering process

ENGLEWOOD, Colo. -- MX Logic, Inc., a leading managed security service provider, today announced the deployment of an anti-spam filter that specifically targets any attachment-based spam variations. The new Deep Content AnalysisSM filter is the latest advancement to the MX Logic Stacked Classification Framework® spam detection system, which is powered by patented technology and combines the most effective spam-fighting filters and techniques in the industry.

PDF (Adobe Portable Document Format) spam is the first variation of attachment-based spam addressed by the new filter, which is now in place to protect all businesses with the MX Logic® Email Defense Service. In PDF spam, spam content is embedded within attached .pdf documents instead of within the body copy of the message. Unlike any other solution on the market, the Deep Content Analysis filter allows all email attachments to be treated holistically and therefore enables MX Logic to analyze these messages in their entirety to determine if the email and/or the attachment contains spam or malware before they reach the customer’s network.

“At the height of the PDF spam outbreak, we were seeing PDF spam comprising between 10 to 15 percent of the overall spam volume with spikes up to 30 percent,” said Sam Masiello, director of threat management at MX Logic. “The shift caused by the increase in PDF spam was just the first wave of what we expect to be the next evolution of email-borne threats. In fact, as image spam volume continues to decline we believe attachment-based spam will take its place and greatly increase. So, we have created the Deep Content Analysis filter, further advancing our Stacked Classification Framework spam detection system, to respond to this threat.”
