Act 1 • Act 2 • Intermezzo • Act 3 • Act 4 • Act 5 Management Summary, Redistributable Documents and Links In the past week we’ve demonstrated that the SORBS reputation data is riddled with mistakes, poor practices, security holes and operational problems, and that the quality of the end result is really too poor to be useful. Today I’m looking at how this information should affect...
Act 1 • Act 2 • Intermezzo • Act 3 • Act 4 • Act 5 Management Summary, Redistributable Documents and Links In the past week we’ve demonstrated that the SORBS reputation data is riddled with mistakes, poor practices, security holes and operational problems, and that the quality of the end result is really too poor to be useful. What does this mean to you though? There are really two aspects:...
Act 1 • Act 2 • Intermezzo • Act 3 • Act 4 • Act 5 Management Summary, Redistributable Documents and Links In the last few days we’ve talked about GFI’s lack of responsiveness, the poor quality of their reputation and blacklist data, and the interesting details of their DDoS claims. Today we’re going to look at (some of) the fundamental problems with GFI’s procedures and...
Act 1 • Act 2 • Intermezzo • Act 3 • Act 4 • Act 5 Management Summary, Redistributable Documents and Links I’ve been stage-managing for a production of The Nutcracker this week, so musical terminology is on my mind. In opera, the intermezzo is a comedic interlude between acts of an opera series. This comedic interlude is about the “DDoS” – a distributed denial of service...
Act 1 • Act 2 • Intermezzo • Act 3 • Act 4 • Act 5 Management Summary, Redistributable Documents and Links Yesterday I talked about GFI responsiveness to queries and delisting requests about SORBS listings. Today I’m going to look at data accuracy. The two issues are tightly intertwined – a blacklist that isn’t responsive to reports of false positive listings will end up with a...
Act 1 • Act 2 • Intermezzo • Act 3 • Act 4 • Act 5 Management Summary, Redistributable Documents and Links A little over a year ago the SORBS blacklist was purchased by GFI Software. I had fairly high hopes that it would improve significantly, start behaving with some level of professionalism and competence and become a useful data source, in much the same way that the SpamCop blacklist turned...
A week or so back I talked about clicktracking links, and how to put them together to avoid abuse and blocking issues. Since then I’ve come across another issue with click tracking links that’s not terribly obvious, and that you’re not that likely to come across, but if you do get hit by it could be very painful – phishing and malware filters in web browsers. First, some...
If you use redirection links in the emails you send out, where a click on the link goes to your server – so you can record that someone clicked – before redirecting to the real destination, then you’ve probably already thought about how they can be abused. Redirection links are simple in concept – you include a link that points to your webserver in email that you send out...
… and the device they’re probably going to read your email on.
@lauter from MailChimp points and laughs at an advertising email from Blackberry-the-company that’s completely unreadable when read on Blackberry-the-device.
That’s really bad marketing on a bunch of different levels.
Our tomcat, Grover, wants to go outside. He wants to go out the side door, so he’s been sitting in front of it, looking at me, then staring at the door. He’s been doing this for about half an hour, intermixed with occasional sad yowling. The back door is open, and he can get from outside the back door to outside the side door in a minute, tops. But he wants to go out the side door...
