  SSH Tunneling - Poor Techie's VPN (Apr 2)
 

"If we see light at the end of the tunnel, it is the light of the oncoming train" ~ Robert Lowell. Oh yes, another good quote. This post is on SSH tunneling, or as I like to call it 'Poor Man's VPN'.

  Mac hacker attack hits more than 600,000 computers (Apr 6)

  Good samaritan hackers politely point out security holes (Apr 3)
 

Who says hackers can't be nice?One group, MalSec, left a calling card on a security firm's website that decisively struck down its claim of being "the largest and most trusted full-service security and life-safety company in the Cayman Islands." But instead of rendering it useless, gave them pointers on how to fix their holes.

Versions 2.5.0 to 2.5.3 are affected.
