| Prepaid fraud detection |
Services Fraud – General |
There is the risk of a fraudulent employee generating PINs for their own use, or to sell on. During the manufacture and distribution of the PINs they are vulnerable to fraud from a third party. |
| Generation of abusive credits |
A CSP makes offers that allow
prepaid subscribers to earn credit
bonuses resulting from inbound
traffic. Artificial inflation of traffic to
the prepaid subscriber increases
the balance resulting in the offers
being abused. This is similar to
PRS (Premium Rate Service)
fraud which involves revenue
inflation through fraudulent postpaid
subscriptions used to generate
traffic to prepaid services with the
postpaid bills remaining unpaid. |
| Prepaid HLR profile manipulation |
Home Location Register (HLR)
contains flags that identify
subscribers as prepaid with a set
service balance. When a call is
placed the HLR flag will direct
to the IN platform to check the
balance. , If the balance runs
out the call will be suspended. A
missing flag can be due to technical
problems, human error or fraud. |
| Prepaid Top-up detection |
Manual recharging |
Fraudulent use of prepaid top-
ups happens when a user
tries to increase credit using a
unauthorized top-up amount, re-
use a voucher within a short time
period or have multiple failed top-
up attempts within a certain period
of time. This type of fraud can
be identified by the detection of
suspicious cases, such as high
frequency recharge, high value
recharge and odd value top-ups. |
