Snowshow Spam on the Rise

The most basic form of spam—a high volume of unsolicited bulk email that is sent from a single IP address—is easily detected and blocked by anti-spam technology today. Snowshoe spam is a new variation on this theme.

With snowshoe spam, the same basic premise is in use, but instead of distributing weight across a broader area, spammers distribute their IP address footprint. Snowshoe spammers spread their message over many different IP addresses, each used in low volume, to send the message.
