-news, in which RSA's Limor Kessem explains how a Linux malware-kit is sold on Russian websites, I have been contemplating about Linux security again.

If there's malware in it, other people might already have noticed it in the source code". At least, that's what I usually hope.
Throw into the mix some easily exploitable Linux routers
, and Googles lax behaviour
with Android security to make me reach for the paracetamol again.
