Phone numbers are now often considered the “trust anchor” for end-user
accounts. In some cases, a user’s valid phone number is their user name.
But what happens when the very phone numbers that are used to verify
and keep end-users secure are given up, recycled and assigned to a new
person?
Phone number recycling is the industry term that refers
to the event when that deactivated/disconnected number gets reassigned
to someone else. Data of recycled phone numbers are not available but is
thought that if users are not diligent in updating their account
information and telcos are not aware of numbers being recycled, it can
lead to increased risks for the integrity of the account.
In the
most basic scenario, the new owner of a phone number is now tied to the
account that the former owner linked to that same number—providing
access to someone else’s account. Alternatively, this can also lead to
the true user being locked out and account notifications, security
codes, password resets and other messages and alerts are not reaching
the end-user
International Center for Investigative Reporting,
(ICIR), recently wrote about confusions that have arisen as a result of
SIM recycling.Imagine the frustration of a phone subscriber who is told
by another that the line he or she is using is not his or hers?
Only
recently, Anthony Okolia was illegally detained for possessing a phone
line he purchased years after it was allegedly abandoned by Hanan
Buhari, daughter of Nigeria’s President.
It was discovered that
the accused had earlier registered the SIM. Fortunately, he was still in
possession of the payment receipt.The incident generated some
controversy. While some questioned legality of SIM swap, others
expressed worry over unlawful detainment of the accused persons. There
are several other Nigerians who have had similar SIM swap experience but
not made their complaints public.
Last year December, Adeleke
Adewolu, executive commissioner on Stakeholder Management (ECSM),
Nigerian Communications Commission (NCC) attributed illegal SIM swaps as
being responsible for the highest cyber threats recorded in the telecom
sector.
David Ogala, a security consultant ha however urged the
Nigerian Communications Commission to take steps to restore trust in
mobile phone.He said that subscribers’ personal experience with services
providers is the most significant factor in determining the level of
trust.
