Email address as identity

A few months ago I was talking about different mailbox tools and mentioned email addresses are the keys to our online identity. They are, email addresses are the magic key that authenticates us and opens access to different accounts.
The bad guys know this too. The Justice department recently announced a plea deal related to compromised email accounts. The individual in question gained access to faculty, staff and student email accounts. They then used access to these accounts to access Facebook, iCloud, Google, LinkedIn and Yahoo accounts.

Mediapost published an article this week referencing a survey performed at this year’s BlackHat conference.

Of 250 hackers polled, 32% said that accessing privileged accounts was the easiest and fastest way to get at sensitive data.
The second most effective route to data, cited by 27%, was access to user email accounts.

Email accounts are the keys to the kingdom. Protecting them is a vital part of protecting yourself online.

Security issues affect us all

I’ve been talking about security more on the blog. A lot of that is because the security issues are directly affecting many senders. The biggest effect recently has been on companies ending up on the SBL because their signup forms were the target of a subscription attack. But there are other things affecting online spaces that are security related. Right now not much of it is affecting email senders, but it’s good to be aware of.
DDOS attacks
There has been an increase in DDOS attacks against different companies and network. Some of the online game sites have been targeted including EA, Blizzard and others. A group called PoodleCorp is claiming responsibility for those attacks.
Another set of DDOS attacks hit Brian Krebs’ website this week. The site stayed up, but Akamai has told Brian they can no longer host his website. His website is down for now and the foreseeable future.
While this activity doesn’t affect marketers directly, it does tell us that there is active development happening on the less legal side of the internet. The volumes of the recent attacks have sent records. They’re also changing in scope and including new kinds of traffic in an effort to knock sites offline. Even more concerning, they appear to be systematically attempting to discover defenses in order to attack the internet as a whole.
Increase in Spam
Spam has been on the decrease over the last few years. Many of us were treating it as a mostly-solved problem. But a new report from Cisco Talos shows that trend is reversing and spam levels are increasing. Current levels are approaching those last seen more than 5 years ago. Cisco Talos has used a number of different sources of data, all showing an increase in spam directly and indirectly.

Target breach started from email

According to Brian Krebs the compromise of Target’s POS system probably originated with a phishing attack against one of Target’s vendors. This attack compromised credentials of the HVAC vendor and possibly allowed the hackers entrance into Target’s systems.
Interestingly, Brian mentions Ariba, a company I’ve been forced to deal by a large customer of ours. I’m not sure if there really is an attack vector where a vendor can get access through Ariba to the internal systems of the customers. However, my experience with Ariba has been frustrating and problematic, so I’ll be happy to believe their security is as broken as their email.
Email is a great way to interact with people and companies. It’s great for growing communities and businesses. But it is also a way for attackers to get access to your computer and the websites you interact with. Protect yourself, and your company, by running security software. And, please, don’t open attachments or click on links in emails and provide usernames and passwords.

Thoughts on filters

One of the questions we received during the EEC16 closing keynote panel was why isn’t there a single blocklist that everyone uses and why don’t ISPs share data more. It would be so much easier for senders if every ISP handled mail the same as every other. But the world isn’t that simple, and it’s not always clear which mail stream is spam and which is good mail.
