The Spam Filter industry, thanks in part to the proliferation of spam gangs and also due to the Internet’s inability to fix the protocol behind email, has continued to remain a crucial piece of software for many organizations.
While big cloud providers such as Google Apps and Microsoft’s Office 365 are bundling spam filtering with their cloud-based email services, there are many complaints about their lack of effectiveness in filtering out junk mail.
The junk mail trend for 2014 has revolved around the Domain Registration Spam Loop. It’s an automated, hybrid spam attack that involves:
- A domain name gets registered
- It gets assigned to an IP address with a neutral Internet reputation
- A massive spam campaign gets launched using the new domain name along with the neutral IP address
- Four to six hours later, most of the Internet has caught on to the scheme and is blacklisting both the domain name and its IP
- Before #4 happens however, a new domain is registered and the process repeats. Over and over again.
We are pleased to say that we’ve developed new, proprietary methods to proactively filter DRSL out.
Here’s a pie chart of total email stats for 2014 thus far:
Virus activity has been close to nil this year, coming in at 0.01% of all email.
Phishing attacks still persist but only represent 1% of all email for 2014.
At a staggering 79%, spam continues to dominate all forms of email.
Legitimate email rounds out the list at 20%.
