Another security problem

I had hoped to move away from security blogging this week and focus on some other issues. But today I see that both CAUCE and John Levine are reporting that there is malware spam coming from a Cheetahmail customer.
Looking at what they shared, it may be that Cheetahmail has not been compromised directly. Given mail is only coming from one /29, which belongs to one customer it is possible that only the single customer account has been compromised. If that is the case, then it’s most likely one of the Cheetahmail users at the customer got infected and their Cheetahmail credentials were stolen. The spammer then gained access to the customer’s Cheetahmail account.  It’s even possible that the spammer used the compromised customer account to launch the mail. If this is the case, the spammer looked exactly like the customer, so most normal controls wouldn’t have noticed this was a spammer.
This highlights the multiple vectors these criminals are using to gain access to ESPs and the mailing systems they use. They’re not just trying to compromise the ESPs, but they’re also attempting to compromise customers and access their accounts so that the spammer can steal the ESPs hard won and hard fought sending reputation.
Everyone sending mail should be taking a long, hard look at their security. Just because you’re not an ESP doesn’t mean you aren’t a target or that you can get away with lax security. You are also a target.

Working around email security

One of the common things I see as a delivery consultant is that companies do their best to set effective policies about email, but make it difficult to comply with those policies. It happens all the time. It’s one of the reasons that the tweets Steve shared about Sec. Clinton’s email server rang so true to me.

One of the commenters on that post disagrees, and uses banks and health care as an example.

Why care about email?

I got my first email address in the very late 80s. I was an intern at a government agency. I learned a lot there: how to sequence DNA, how to handle radioactive material, how to handle human pathogens, and how to send email. I got my first non-work non-school address in the mid-90s. One of the first things I did was join some mailing lists.
One of them was a list for folks who had pet rabbits. I met a lot of people there, both online and in person. As with many people we meet through a shared interest as our interest wanes the relationships change. Some relationships were maintained, but some of us lost touch with one another. Moves, job changes, email address changes, they all affect our ability to maintain relationships online. I kept in touch with some, one was the maid of honor at my wedding and a few years ago I was the maid of honor at hers. I lost track of others.
