when other people download viruses
@brennenbyrne

zombies
@brennenbyrne

23. sites infect visitors’ computers
zombies attack sites
visitors join zombie army
bigger army attacks more sites
@brennenbyrne

from millions of different computers

response to our better defenses
as wordpress becomes a better target
the incentives for breaking it rise
@brennenbyrne

27. two step
@brennenbyrne

28. something you
something you
@brennenbyrne
the steps
know
have
something you are

29. the old way of doing this meant:
!
1. typing your password
2. getting a text with a bunch of numbers
3. typing in the bunch of numbers
!
(google authenticator)
@brennenbyrne

30. @brennenbyrne
clef, the plugin i work on, skips
the password to make
two-factor much easier.

31. ssl
@brennenbyrne

32. @brennenbyrne
!
ssl = safe safe lock
*it actually stands for “secure socket layer”

33. without ssl, everything is public
@brennenbyrne
only do stuff you wouldn’t
mind standing on a table
and yelling about in a
coffee shop
i.e. no passwords or credit cards

34. password
rot
@brennenbyrne

35. @brennenbyrne
your password is strongest
on the day you set it

36. 2. more computer power available
1. more time for attacker to crack
3. greater chance you’ve reused
@brennenbyrne

37. passwords pit our
memories against
computer brute force —
we are going to lose
@brennenbyrne

38. what to do
@brennenbyrne

39. @brennenbyrne
one weird trick to protect
your site from all attacks

40. @brennenbyrne
delete it.

@brennenbyrne
otherwise
install bruteprotect and cloak
