Spam supporting presidential hopeful Ron Paul filled inboxes this week as zombie computers spewed thousands of messages to recipients, according to spam experts. The spam supporting Paul was sent using the same illegal spam methods used to distribute masculinity enhancement products and pump-and-dump penny stock schemes.

Experts suggest getting used to it. They expect that during this election cycle things are going to get ugly as campaigns, spammers, unruly supporters, and even rival camps use blogs, inboxes, YouTube videos, and search engines to spam the vote.

In this case, the Ron Paul 2008 Presidential Campaign Committee vigorously denies sending the spam, approving its distribution, or having any ties to its senders. Security experts analyzing the deluge agree the official organization is likely not the source.

Or, as everyone discussing the deluge noted, the spam may have been sent by someone trying to make Paul look bad by associating him with spamming.

"It's a tactic that we've seen many times in the past," says Sam Masiello, director of threat management at e-mail security firm MX Logic. "We just didn't expect to see it start happening so early this year."

Security experts contacted report seeing this week waves of identical spam that supports candidate Paul. In each instance, the spam was sent using a botnet, which is a network of hijacked consumer or commercial PCs that are often used surreptitiously by hackers to send spam.

MX Logic's Masiello says the spam messages sent on Paul's behalf didn't contain malicious surprises.

Instead, the Ron Paul spam contained only written requests to support Paul's presidential bid. E-mail subject lines of the spam messages featured various come-ons, such as "Who Is Ron Paul?" "Ron Paul Eliminates The IRS!" and "Ron Paul Wins GOP Debate!"

"We suspect an overzealous and well-intentioned Ron Paul supporter sent these messages," says Jesse Benton, spokesperson for the Ron Paul 2008 Presidential Campaign Committee. Benton suggests the spam may have been sent by someone interested in discrediting Paul by associating his campaign with spamming.

A Paul spam surge was spotted Monday by several security services, including SophosLabs, which quickly began blocking the messages. MX Logic tracked the spam coming from hijacked PCs from Europe, South America, and Australia. The security services say volumes of Paul spam have dropped considerably by Friday.
