In Political Activists Need Linux, "Brad" briefly describes the HB Gary Federal scandal. For those of you who have played Rip van Winkle for the last three months or so, HB Gary Federal makes malware to order, and their clients include the US federal government and a number of large US businesses. "Brad's" conclusion is that political activists of any stripe, and their friends, political or not, should not be running Windows.
Ironically, HB Gary Federal fell because they made three mistakes. First, they took on someone who were better at cracking computers than they were at securing them. Second, they used the same account to develop software and to administer their mail server. Third, they ran Windows.
Now comes another attack on political activists. This one is aimed at Microsoft's Internet Explorer web browser. The folks at Google who found the attack echoed Microsoft's advice to install their patch immediately. As the author of the article says, it is even better to stop using IE entirely.
Better yet, don't use Windows at all.
