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.

Another kind of email breach

In all the recent discussions of email address thievery I’ve not seen anyone mention stealing addresses by abusing the legal system. And, yet, there’s at least one ambulance chasing lawyer that’s using email addresses that were never given to him by the recipients. Even worse, when asked about it he said that the courts told him he could use the email address and that we recipients had no recourse.
I’m not sure the spammer is necessarily wrong, but it’s a frustrating situation for both the recipient and the company that had their address list stolen.
A few years ago, law firm of Bursor and Fisher filed a host of class action lawsuits against various wireless carriers, including AT&T. At one point during the AT&T lawsuit the judge ruled that AT&T turn over their customer list, including email addresses, to Bursor and Fisher. Bursor and Fisher were then to send notices to all the AT&T subscribers notifying them of the suit.
This is not unreasonable. Contacting consumers by email to notify them of legal action makes a certain amount of sense.
But then Bursor and Fisher took it a step further. They looked at all these valid email addresses and decided they could use this for their own purposes. They started mailing advertisements to the AT&T wireless list.
