Fraud Management - PABX Fraud

Whilst telecoms operators have no liability for PABX fraud, many operators are realising that alerting their corporate customers to fraud helps to avoid potential disputes and forge good customer relations.

Most PABX installations have dial-in access used for maintenance purposes by engineers and this is what fraudsters look for to gain access. Once a list of possible numbers is established (data ports, such as faxes and modems) the attackers use code-breaking scripts to bypass any password control. Less sophisticated attacks are carried out through voicemail systems, where the attacker looks to gain access to outside line.

Minotaur Fraud Management Solution comprises a range of features to detect PABX fraud quickly and effectively, on both traditional and IP based systems.

• Advanced profiling ­ providing visibility of the behaviour of both individual subscribers and/or a group subscription (such as corporate). Usage profiling analysis identifies and flags up any changes ­ such as variation in call destination, call lengths or time of calls made.
• Destination profiling ­ monitoring increases in call volumes to destinations to alert for potential attacks (irrelevant of the source of the calls), means that fraud can be identified event if the attack is sourced from several accounts
• Rules and thresholds ­ these work on more than just call volume or duration basis; they also include customer specific or account type specific rules and thresholds, as well as combinations of destination, volume, call length and time of day variables.

Neural Technologies offers PABX fraud management within its Minotaur fraud solution or as a low cost stand-alone module available via the cloud.
