In this post, we’ll profile a SIP-based<\/strong><\/a>, API-supporting fake caller ID\/SMS number supporting DIY service, and discuss its relevance in the overall increase in TDoS underground market propositions.<\/p>\n

More details:<\/p>\n

Sample screenshots of the service in action:<\/strong><\/p>\n

\"SIP_CallerID_SMS_API_Russian_Managed_Service_04\"<\/p>\n

\"SIP_CallerID_SMS_API_Russian_Managed_Service\"<\/a> \"SIP_CallerID_SMS_API_Russian_Managed_Service_02\"<\/a> \"SIP_CallerID_SMS_API_Russian_Managed_Service_03\"<\/a><\/p>\n

Although the featured screenshots offer a fake caller ID service verification on behalf of the cybercriminals operating the service — advertised publicly since 2011 — that’s just the tip of the iceberg, due to the standardized nature of SIP<\/strong><\/a>, as well as the availability of an API allowing virtually anyone to build custom TDoS (Telephony Denial of Service) attack tools while using their infrastructure.<\/p>\n

What’s ultimately driving the rise of the\u00a0TDoS (Telephony Denial of Service)<\/a><\/strong>\u00a0underground market segment? Is it the existence of bulletproof infrastructure exclusively utilized for malicious and fraudulent purposes, or the systematic abuse of legitimate infrastructure<\/strong><\/a> in an attempt by the vendors of these services to blend with it in an attempt to make it harder to detect their activities?<\/p>\n

Not surprisingly, based on our research, it’s currently a combination of both, with the abuse of legitimate services offered by SIP providers and mobile carriers<\/strong><\/a>, as well as the systematic introduction of bulletproof SIP infrastructure. We believe that due to the industry’s current ‘catch up mode’ in regard to this emerging DoS (Denial of Service) vector, cybercriminals will continue successfully launching these attacks, utilizing both legitimate and purely malicious infrastructure, to achieve their objectives.<\/p>\n
