Recently the FBI released a warning in cooperation with the Internet Crime Complaint Center (IC3.gov) that documented the risks behind Telephony DDoS attacks. These types of attacks are essentially used to jam up phone lines so no more calls can be made or received. It is obvious why it may be dangerous when this type of attack targets emergency services. A matter of seconds can be all it takes to make a difference in some situations when life saving measures are needed, and if phone lines are jammed up, this could result in the injury or death of someone in need of help. This is not the first time the FBI and IC3 have warned of these attacks as they released a similar warning back in 2013. Attackers can use software tools that make it very easy to carry out these attacks, meaning not much skill is needed on the part of an attacker. Unfortunately, these types of attacks are also hard to detect due to the bad actors spoofing their numbers on every call.
