Spammers send out mass emails not only to directly net money from unsuspecting users, but also to install malware on a computer or network. All it takes is one person at one company clicking on the wrong link for an entire organization’s network to be compromised. From May 23 through June 23, more than 172 million malware-laden emails were sent out, according to numbers from SenderBase.
While email spam remains a global problem, it is luckily one that is fairly easy to mitigate. For starters, a spam filter at the gateway either as a standalone point solution, or as part of a next-generation firewall or unified threat management solution, plus a robust anti-spam email client will keep the vast majority of spam out of the inbox. A good system should be able to keep out at least 99 percent of all spam missives.
But, since spam is unlikely to dissipate or disappear anytime soon, some diligence will always be required on the part of the end user. Just knowing that all emails that seem off or contain funky spellings shouldn’t be opened, and that only trusted URLs should be clicked on, is the best defense for ensuring that what little spam does enter the inbox does not become a threat.
