Botnets and viruses and phishing, oh my!

MessageLabs released their monthly report on email threats yesterday. Many media outlets picked up and reported that 41% of spam was from a the Rustock botnet.
Other highlights from the report include:

  • Spam accounts for over 92% of all email.
  • 95% of spam was sent from botnets at the end of July 2010.
  • One in 327 emails contains malware and one in 363 emails is a phish.
  • The number of rustock infected machines is falling, but the amount of mail each one is sending is increasing.
  • More than 107 billion emails are being sent through botnets every day.

The end of the report things that, to my mind, should be of significant concern to legitimate marketers. Spammers are adopting tactics from marketers in order to hook users and probably evade detection by ISPs. These include personalizing email (examples) and using image only spam (examples).
One of the recommendations that I’ve repeatedly made here is that legitimate senders should not do things that make their mail look like spam. Sending image only emails is one way for marketers to look like spammers.
The other thing that stands out to me from this report is how small the percentage of legitimate marketing email is. 92% of email is spam. Let’s assume that no one reading this blog is part of that 92%, that means only 8% of mail is not-spam. How much of that is marketing is probably up for debate, but I don’t think that more than 50% of legitimate email is marketing (the other 50% is mail from friends and family, social networking notices and discussion groups).
With those numbers, I can understand why ISPs don’t focus as much as some marketers might like on false positives with spam filtering. In percentage terms it is a tiny fraction of mail and most consumer ISPs provide end users with the ability to override bulk foldering if the recipients really want that mail.
ISPs are the front line against criminals on the Internet. Blocking email is one of the primary ways they protect people. Given the extent of spam and malevolence of spammers they are to be commended for creating systems that have such a low percentage of false positives.

Appendleads is not unusual

I called out David Williams from appendleads.com yesterday for his spam. Sure he’s a spammer, his database is full of garbage information and his email violates CAN SPAM but he’s not that unusual in the realm of list sellers. He is very typical of the people I see offering lists for sale.
List sellers are the internet version of used car salesmen. Everyone knows they are slimy sales guys who will do anything to close the sale. They don’t have a real web presence, just visit appendleads.com and see what I mean.
And yet, people still buy lists from them! I have no doubt that my spammer friend has a nice little business selling email addresses. He sends out spam, he gets a few responses, makes a tidy profit and then sends out another spam, hooks a few more people and makes more money.
OK, so not all list sellers are like appendleads. Some of them go so far to build a website. But at the core they’re the same. They are selling data that isn’t clean, it’s not opt-in, it’s not been verified.
This is why so many of us harp on not buying lists. The sales guys talk a great game, but they aren’t selling what purchasers think they’re getting. They also don’t care. They have no incentive to clean up their data. They have no incentive to accurately represent what they’re selling. All of the risk is on the person that sends the email. Once they have their money, the buyer is on their own.
Can you ever successfully purchase a list? I’m sure some senders have. But that experience is closer to winning more than a thousand dollars in the lottery than an actual good business decision.

Did anyone actually look at this email before sending?

I received spam advertising AARP recently. Yes, AARP. Oh, of course they didn’t send me spam, they hired someone who probably hired someone who contracted with an affiliate marketer to send mail.
The affiliates, while capable of bypassing spam filters, are incapable of actually sending readable mail.

Legitimate mail in spamfilters

It can be difficult and frustrating for a sender to understand they whys and wherefores of spam filtering. Clearly the sender is not spamming, so why is their mail getting caught in spam filters?
I have a client that goes through this frustration on rare occasions. They send well crafted, fun, engaging content that their users really want. They have a solid reputation at the ISPs and their inbox stats are always above 98%. Very, very occasionally, though, they will see some filtering difficulties at Postini. It’s sad for all of us because Postini doesn’t tell us enough about what they’re doing to understand what my client is doing to trigger the filters. They get frustrated because they don’t know what’s going wrong; I get frustrated because I can’t really help them, and I’m sure their recipients are frustrated because they don’t get their wanted mail.
Why do a lot of filter vendors not communicate back to listees? Because not all senders are like my clients. Some senders send mail that recipients can take or leave. If the newsletter shows up in their inbox they may read it. If the ad gets in front of their face, they may click through. But, if the mail doesn’t show up, they don’t care. They certainly aren’t going to look for the mail in their bulk folder. Other senders send mail that users really don’t want. It is, flat out, spam.
The thing is, all these senders describe themselves as legitimate email marketers. They harvest addresses, they purchase lists, they send mail to spamtraps, and they still don’t describe themselves as spammers. Some of them have even ended up in court for violating various anti-spam laws and they still claim they’re not spammers.
Senders are competing with spammers for bandwidth and resources at the ISPs, they’re competing for postmaster attention at the ISPs and they’re competing for eyeballs in crowded inboxes.
It’s the sheer volume of spam and the crafty evilness of spammers that drives the constant change and improvement in spamfilters. It’s tough to keep up with the spamfilters because they’re trying to keep up with the spammers. And the spammers are continually looking for new ways to exploit recipients.
It can be a challenge to send relevant, engaging email while dealing with spamfilters and ISPs. But that’s what makes this job so much fun.
