DHS Partners with SecureLogix to Prevent TDoS Attacks

Cybersecurity attacks happen all too often, and attackers are becoming more bold and sophisticated by disrupting critical phone systems and putting 911 emergency call centers at risk. Similar to Distributed Denial of Service (DDoS) attacks on critical online services, Telephony Denial of Service (TDoS) attacks render emergency systems unavailable by saturating them with bogus calls and potentially causing great harm to those who truly require urgent first responder attention.  

New Bill Would Push for Cybersecurity Improvements at 911 Call Centers

Faced with national 911 systems deemed increasingly vulnerable to cyberattack, Sens. Bill Nelson, D-Fla., and Amy Klobuchar, D-Minn., will introduce a bill within the next few weeks to federally fund and hasten the national transition to next generation 911 (NG911) systems.

The Next Generation of Cyber Attacks — PDoS, TDoS, and Others

Another attack type that has flown under the radar is Telephony Denial of Service (TDoS). This attack type will likely rise in sophistication and become a key tool in cyber attackers’ arsenals, particularly those who are more interested in wreaking havoc than having financial gain as a motivator

The Top 5 VoIP Security Risks and Their Controls

Businesses often ponder on the reliability and overall quality of VoIP telephony system. This is a major concern which leads such businesses to consider the dangers of data security risks. In spite of the few controversial security breaches in the past, VoIP technology has advanced and transformed into a more robust business tool.

Pulling our head out of the sand on cybersecurity

Imagine dialing 911 during a crisis in your’s or a loved-one’s life. Now, imagine that no one answers your call for help. Why? Because a cyber-criminal has locked the 911 call center’s ability to receive your call.

Exploring Telephony Denial of Service

In a denial-of-service (DoS) attack, the goal is to make a resource unavailable to its intended users, usually in a temporary interruption or suspension of services. DoS attacks are well known in data systems and networks, but can also happen to a telecom system or network.

iOS WebView Auto Dialer Bug

iOS WebViews can be used to automatically call an attacker controlled phone number. The attack can block the phone's UI for a short amount of time and therefore prevent the victim from canceling the call. The bug is an application bug that likely is due to bad OS/framework defaults. One major issue with this vulnerability is that it is really easy to exploit. App developers have to fix their code as soon as possible.

2016 R&D Showcase: Protecting Emergency Services from Complex Distributed Denial of Service

In February 2016, the DHS Science and Technology (S&T) Directorate Cyber Security Division (CSD) hosted its R&D Showcase and Technical Workshop. The event featured innovative CSD technologies that address current and complex cybersecurity challenges. In this video, showcase presenter Mark Collier of SecureLogix discusses protecting emergency services from complex distributed telephone denial of service attacks.
