$30K Telephony Incident In Development Office: Security Breach Report

It's been a while since we've had a security breach worth mentioning (that we know of). Last week we had one, and it was an eye-opener. . A small development office in Western Europe was informed by the local telephone company that a high number of calls were being made from the office's IP telephony setup to a Middle Eastern country. When we looked into it, we found that in just 15 days, over $30,000 in calls had been made to several Middle Eastern countries, as well as Russia, China and a couple of Central American nations.. A modest tech company in Northern Europe encountered a significant compromise—more than €25,000 in overseas communications generated within a mere two weeks..

Understanding Automated Caller ID and ANI Spoofing in VoIP Security

What is ANI / Caller ID spoofing? ANI / Caller ID spoofing is setting the ANI / Caller ID on the outgoing call you are making to a 10 digit number of your own choosing. Traditionally it has been a complicated process either requiring the assistance of a cooperative phone company operator or an expensive company PBX system. . . .. What is Caller ID? Caller ID is a service provided by most telephone companies (for a monthly cost) which will tell you the number / name of an incoming call. [Definition: Hack FAQ ] What is ANI? Automatic Number Identification is a system used by the telephone company to determine the number of the calling party. There are believed to be two types, "FLEX ANI" (used for e.g. verification services such as voicemail) which is relatively easy to spoof, and "Real Time ANI" (used only for billing purposes on e.g. 800 numbers) which is harder to spoof. [Definition: Hack FAQ ] What is ANI / Caller ID spoofing? ANI / Caller ID spoofing is setting the ANI / Caller ID on the outgoing call you are making to a 10 digit number of your own choosing. Traditionally it has been a complicated process either requiring the assistance of a cooperative phone company operator or an expensive company PBX system. What is Automated ANI / Caller ID spoofing? Automated ANI / Caller ID spoofing is setting the number you are calling from without the use of an operator / company PBX system. By far the easiest method thanks to the increasing take-up of internet telephony services are VoIP (Voice over Internet Protocol) service providers who allow you when using their service to set whatever caller ID you like (which is also used as ANI).

Understanding Phreaking and SIP Threats in VoIP Security

Increasing use of voice-over-IP technology could result in a return to "phreaking" - hacking of telephony systems to make free calls. Security expert Matt Barrie said VoIP was cheap and increasingly popular, but it introduced many vulnerabilities of traditional Internet Protocol networking to voice telephony. Mr Barrie, a lecturer in security at the University of Sydney and former manager of the Packetstorm security portal, said telephone network operators had spent years coming to terms with security issues in voice transmission, which could re-emerge as VoIP grew. Internet security centre CERT found a vulnerability in the fledgling IP Session Initiation Protocol (SIP) in February. Among other things, the vulnerability could be used to cause denial of service attacks. The link for this article located at news.com.au is no longer available. . Explore the implications of VoIP technology's rapid advancement on the phreaking phenomenon and its potential security risks..
