Hacking of businesses’ and other organisations’ telecoms is a costly fraud that has impacted on numerous Hertfordshire businesses. It can happen at any time of the year, but systems are particularly vulnerable during periods when phones are left unmonitored for extended periods, such as the Easter break, bank holidays, summer holidays, and Christmas.
This crime happens when an unmonitored company telephone system (e.g. office phones set to an automated attendant over a long weekend) is hacked and calls are routed through the victim’s telephone system to International premium rate numbers. This earns the criminals a revenue share on every call, and leaves the victim organisation liable for each of those premium rate calls, resulting in a huge telephone bill – sometimes hundreds of thousands of pounds.
The National Fraud Intelligence Bureau, in conjunction with other partners, has produced the attached guide, which provides advice and guidance about how to protect your telecoms system from fraud. Organisations may wish to flag this document to relevant colleagues, and consider your organisation’s resilience to such attacks.
