NACHA Spam / 85.25.189.174

Another NACHA spam, leading to malware on 85.25.189.174:

From:     CarleySpan@hotmail.com
Date:     19 April 2012 21:25
Subject:     Your ACH transaction N73848938

The ACH credit transfer, initiated from your checking acc., was canceled by the other financial institution.

New Blogger interface: It's all too horrible to contemplate.

If you use Blogger, you'll know that it has a new interface. It's horrible. OK, the old interface was horrible but usable at the same time. This is just horrible, with the familiar looking elements seeming sprinkled at random over the new interface.

There are a lot of companies at the moment doing a similar thing.. making over their tried and tested (but tired) old software interfaces and coming up with something pastel-ly and awful. Or perhaps I'm just a Luddite?


Update: you can share your feedback on the Blogger forum which is full of similar complaints.

There are three hyperlinks in the message, two of them are to LinkedIn and one of them is to a fake pharma site on mysalepharmacy.com on 178.19.108.195 in Poland.

Personally, I hate LinkedIn emails. Blocking everything that appears to be from linkedin.com will not have any adverse impact on your life.
