Second Hand Mobiles Contain Personal DataBy Cpp, PRNE

YORK, England, March 22, 2011 - People are unsuspectingly selling their personal information to complete
strangers as a new report from CPP finds half (54%) of second hand mobile
phones contain extensive personal data.
Second hand mobile phones and SIM cards purchased on eBay and used
electronics shops by life assistance (
www.cpp.co.uk/identity-protection/) company CPP were examined in a
live experiment to see what personal information was available on the
handsets and whether it constituted a threat to their former owners'
The experiment revealed 247 pieces of personal data* that had been
carelessly left on a range of mobile phones and SIM cards. The personal data
included credit and debit card PIN numbers, bank account details, passwords,
phone numbers, company information and log in details to social networking
sites like Facebook and LinkedIn.
In research that supported the experiment, half of second hand mobile
owners said they have found personal information from a previous owner on
mobile phones and SIM cards they have purchased second hand.
Worryingly, the vast majority (81 per cent) of people claim to have wiped
their mobiles before selling them, with six in ten confident they have
removed all of their personal information from them. However, the experiment
revealed that 54 per cent of mobile phones and SIM cards contained sensitive
personal information putting people at unnecessary risk of identity and card
The variance could be explained by the fact that most people who claimed
to have 'wiped' their handsets tried to erase the data manually - a process
that security experts acknowledge leaves the data intact and retrievable.
And it seems personal information comes cheap with individuals selling
their old handsets and SIMs for an average price of GBP47.
As people rely heavily on their mobile phones to store personal data such
as email addresses, social networking log in details, banks account details
and even debit and credit card PIN numbers, CPP is calling on people to make
sure they remove all of their personal and financial information from their
mobile phones and undertake adequate security measures to protect themselves
from identity theft (www.cpp.co.uk/identity-protection/am-i-at-risk/).
Mobile data expert from CPP, Danny Harrison said: "This report is a
shocking wake up call and shows how mobile phones can inadvertently cause
people to be careless with their personal data. With the rapid technology
advancements in the smartphone market and new models released by manufactures
multiple times a year, consumers are upgrading their mobiles more than ever
and it is imperative people take personal responsibility to properly manage
their own data.
"If they do sell or recycle them online or even give them to friends and
family, they need to ensure they remove all their personal information
thoroughly and consider the serious consequences of not doing so."
Senior Vice President of CRYPTOCard Jason Hart, who was commissioned by
CPP to carry out the experiment said: "The safest way to remove all of your
data from a mobile phone or SIM card is to totally destroy the SIM and double
check to ensure that all content has been removed from your phone before
disposal. With new technology does come new risks and our experiment found
that newer smartphones have more capabilities to store information and that
information is much easier to recover than on traditional mobiles due to the
increase of applications."
CPP's top tips on wiping your mobile phone of personal information:
1. Restore all factory settings - this is the first step that you should
take as it is the easiest precaution before disposing of the unit, but
factory resets are far from permanent so follow steps 2 - 4 to protect your
2. Remove your SIM card and destroy it
3. Delete back-ups - even if your smartphone, PDA or laptop data is
securely removed from the mobile device, it can continue to exist on a back
up somewhere else
4. Log out and delete- make sure you have logged out of all social
networking sites, emails, wireless connections, company networks and
applications. Once you are logged out make sure you delete the password and
5. Various passwords - avoid using the same ID/password on multiple
systems and storing them on your mobile phone, if you are going to store them
on your phone use a picture that reminds you of the password
6. If you are selling on your phone ensure you ask for it to be wiped to
be on the safe side
7. Don't store vast amounts of personal information on your mobile phone
8. Make sure you check your bank statements regularly to monitor for
9. Remember the Golden Rule: Identity thieves are experts at spotting an
opportunity to steal your identity and only need a few personal details
