Differences with PC
Although similar OSes are being used,
differences exist:
−
Lesser users of mobiles are less “tech literate”
−
Implies that it is difficult to “rollout security
patches” to phones already sold
−
Mobiles are always “connected” and switched
on
−
“Environment” keeps changing
Imagine one infected phone in a stadium full of
people

Differences
On the positive side:
−
Several variants of phones exist
A malware for one type of phone may not
necessarily be able to infect others
−
E.g., A virus that uses an MMS exploit cannot infect a
phone that does not have that facility at all
−
Mobile malware not yet causing critical harm
At most
−
they increase the user's billing, or
−
cause the mobile phone to stop working (can be restored
by a factory reset)
