Emerging threat: CryptoWall


CryptoWall is a digital ransomware that encrypts files on the infected machine and any connected file shares or drives. CryptoWall is distributed through phishing emails, malicious advertisements, compromised web sites, and as fake updates for applications such as Adobe Reader, Adobe Flash, and Java.

TDoS attacks overload the telephone network, preventing legitimate telephone calls from being placed or received. Attacks against SLTT emergency lines, primarily at public safety answering points (PSAP) such as 9-1-1 centers, but also including utility department emergency numbers and other emergency numbers, remain a continuing threat. There is a relatively low risk of TDOSes occurring, however an attack against a PSAP could endanger emergency responders and citizens if the TDOS prevents them from contacting the PSAP.

Emerging Threat: Internet of Things (IoT)


IoT refers to internet-enabled electronic devices which are not computers, smartphones, or tablets. These may include lightbulbs, refrigerators, coffee makers, and toys, and are internet-enabled to facilitate ease of use for owners. For instance, with a light bulb connected to the internet, it is possible for the owner to use a smartphone application to remotely turn it off and to monitor its power usage. Unfortunately, these devices frequently do not contain security components, so it may be possible for a remote attacker to use such a device to start a fire (e.g.
