Specialist Witness Corner: Smart Phone Hacking
First of all, the tirade - it's not hacking! (well technically it is - however it's not some expensive complex technical attack calling for specialist knowledge and also tools).
A lot of individuals are under the impact that cellphone voicemail is
just available from the cellphone itself as well as some may also
believe that messages are kept on the phone. In fact, messages are
videotaped at the mobile network suppliers' information centres and
repeated over the network when the customer dials in to select them up.
It isn't even essential to have access to the cellphone itself to obtain
access to somebody's voicemail account - calling their number while the
phone is off or hectic on another telephone call leads to call
diversion so a message can be left, and this is where the "Swifthackers"
can start. By pressing the appropriate key series throughout the
"please leave a message" welcome message, any person can reach the food
selection which allows voicemail to be repeated. It's an attribute
developed to let users listen to their messages from throughout the
world, whether their phone is working or otherwise, and also is
genuinely beneficial - yet it produces a backdoor through which messages
can be accessed.
Certainly, a PIN is called for to access to the mailbox yet many people
leave the default PIN on their account, as well as these are extremely
well recognized - a lot of are released on the network service
providers' sites or are offered in the manuals available with any kind
of phone or SIM from the supplier.
In other cases, PINs can be presumed similarly as passwords by doing a
little bit of background research study to find out things like
birthdays of relatives, buddies or family pets, various other
substantial dates or registration varieties of vehicles. Other
techniques, like social engineering - where meticulously crafted
questions and behavior are used to obtain the target to disclose their
PIN or even simply "shoulder surfing" (viewing someone enter their PIN
while they listen to their messages) can be very successful too.
For some individuals this can result in personal data being divulged,
while for businesses it could be utilized to find sensitive material.

If you do not need voicemail, transform it off. If you do require it -
don't utilize the default PIN, use a number which isn't connected with
anything that is undoubtedly linked to you - as well as alter it on a
regular basis. Stay clear of evident PINs like 1111, 1234, 9999 and so
forth - treat it like the PIN for your bank card, it might have similar
worth to somebody that wishes to spy on you. The very same guidelines
additionally apply to the answering machine on your land line - the
majority of them have remote access capacities so anybody who dials your
number might pay attention to your messages if they can guess the gain
