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;
