software obscurity

IE has been beaten up over the years, and now that Firefox has gained ground, it also is under fire. While Office has been beaten up last year, now perhaps Open Office will be subjected to the lean eyes of the hacking underground. This post by Brian Krebs is timely, but I particularly love the first couple comments; the first about Open Office, and the second about a just-today-released-patch for an issue in Open Office.
As applications keep getting attacked, especially Office and web browsers, more and more people are scattering over to lesser-known and oft-times free software to accomplish their tasks, myself included. But just because it has not been hit yet, does not make it secure. It might be a little bit safer to use as the odds of an attack are lower, but obscurity alone does not necessarily provide security.
