Indictments in Yahoo data breach
Today the US government unsealed an indictment against 2 Russian agents and 2 hackers for breaking into Yahoo’s servers and stealing personal information. The information gathered during the hack was used to target government officials, security employees and private individuals.
Email is so central to our online identity. Compromise an email account and you can get access to social media, and other accounts. Email is the key to the kingdom.
Large companies (un?)knowingly hire spammers
This morning, CSO and MacKeeper published joint articles on a massive data leak from a marketing company. (Update: 2019: both articles are gone, a cached version of the CSOnline link is at https://hackerfall.com/story/the-fall-of-an-empire-spammers-expose-their-entire) This company, River City Media (RCM), failed to put a password on their online backups sometime. This leaked all of the company’s data out to the Internet at large. MacKeeper Security Researcher, Chris Vickery discovered the breach back in December and shared the information with Spamhaus and CSO online.
The group has spent months going through the data from this spammer. As of this morning, the existence of the breach and an overview of the extent of their operation were revealed by CSO and MacKeeper. Additionally, Spamhaus listed the network on the Register of Known Spamming Operations (ROKSO).
There are a couple interesting pieces of this story relevant to legitimate marketers.
The biggest issue is the number of brands who are paying spammers to send mail from them. The CSO article lists just some of the brands that were buying mail services from RCM:
Who leaked my address, and when?
Providing tagged email addresses to vendors is fascinating, and at the same time disturbing. It lets me track what a particular email address is used for, but also to see where and when they’ve leaked to spammers.
I’d really like to know who leaked an email address, and when.
All my inbound mail is sorted into “spam” and “not-spam” by a combination of SpamAssassin, some static sieve rules and a learning spam filter in my mail client. That makes it fairly easy for me to look at my “recent spam”. That’s a huge amount of data, though, something like 40,000 pieces of spam a month.
Finding the needle of interesting data in that haystack is going to take some automation. As I’ve mentioned before you can do quite a lot of useful work with a mix of some little perl scripts and some commandline tools.
I’m interested in the first time a tagged address started receiving spam, so I start off with a perl script that will take a directory full of emails, one per file, find the ones that were sent to a tagged address and print out that address and the time I received the email. I can’t rely on the Date: header, as that’s under the control of the spammer, and often bogus. But I can rely on the timestamp my server adds when it receives the email – and it records that in the first Received: header in the message.
More security problems
I know a lot of people are putting all their eggs in the 2 factor authentication (2FA) basket as a solution to the recent breaches. Earlier this year, however, RSA had their internal systems breached and unknown data was stolen. Speculation from a lot of sources is that the information stolen from RSA by the attackers could be used to infiltrate systems protected by 2FA.
Today I, Cringely reports that a very large U.S. defense contractor may have been breached despite protection by SecurID. Anyone who has been around folks that work for defense contractors, or even just people with security clearances, knows that security and secrecy becomes second nature. They are naturally suspicious and careful, particularly when interacting with secure systems.
What should really concern anyone thinking about implementing security is that the defense contractor’s security folks implemented extra security after the RSA breach, but someone still managed to infiltrate their systems.
Whatever happens with RSA and the defense department, it’s pretty clear that 2FA is not a panacea. And even when we’re talking about security experts, including defense contractors and RSA, hackers can still get into their systems.
Many of the compromises start with spam linking to payloads. In fact, just last night another email expert had their gmail account compromised, resulting in virus being sent to multiple mailing lists and individuals. Some of the compromises happen through Facebook with links that fool people who should know better.
Security is critical for everything on the internet. But recently the attackers seem to be gaining the upper hand over the defenders. When even the experts are compromised, what chance does the average user have?
UPDATE: Reuters reports that the defense contractor was Lockheed.
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.
Security framework document published
The Online Trust Alliance has published a security framework for ESPs.
Overall, I think it’s a useful starting point. I don’t agree with all of their suggestions. Some of them are expensive and provide little increase in security. While others decrease security, like the suggestion to force regular password changes.
I think the most important part of the document is the question section. The key to effective security measures is understanding threats. Answering the self assessment questions and thinking about internal processes will help identify potential threats and their vectors.
The document is not a panacea, and even companies that implement all of their recommendations will still be open to attacks from other avenues. But it certainly is a very good way to open the security discussion.
