What are Message-based Threats?Message-based threats are those threats that enter via messaging systems, such as spam, which accounts for over 95% of all email traffic worldwide. While many people recognize spam as a nuisance, most don’t realize that it is increasingly becoming a vehicle for inserting new threats into the environment. |
To avoid blacklists, today’s attackers hijack legitimate IP addresses to launch massive spam attacks. In some instances, spammers steal whole blocks of addresses from a company’s mail server then use them for spam blasts of phishing attacks, malicious web links, and malware-carrying attachments.
Why should you care?
Spam not only consumes valuable resources, it is a vehicle for cybercriminals to transport malicious code into the heart of a business—its messaging system.How to Protect Your Business
