INTERNATIONAL REVENUER SHARE FRAUD

BACKGROUND

• Pune based NGO used VOIP Servers for attending incoming calls only;
• Servers did not facilitate outgoing calls;
• Received an exorbitant telecom bill of Rs. 50 lakhs;

CHALLENGES

• Telecom Service Provider was forcing the NGO to pay the amount;
• No answer to why such an exorbitant bill since the organization would function only for a limited time during the day;

STRATEGY

• Investigations were performed on servers;
• Servers were found to be compromised;
• System hardening was ensured;
• Firewall was properly configured;
• Public Network PRI Line Servers were secured;

IMPACT

• Based on the investigation, the NGO was freed from the liability of paying the exorbitant bill;
• No litigation was initiated by the Telecom Service Provider;
• It was discovered that a Hacker made outgoing international calls to 12 specific numbers in 12 different countries;
• Calls were made at a time when NGO was not functional and hence could not have been ordinarily traced and were charged at exorbitant rates;
• Measures were adopted for protection of VOIP Servers from being compromised in future;
