Tech Tip Thursday – Default IoT Passwords

The Mirai malware relied on the average user, who just wants their “stuff” to work, to leave the default credentials (username and password) on their Internet of Things (IoT) devices (e.g. IP cameras, routers, DVRs, refrigerators). Once the devices were compromised, they were added to the botnet to perform Distributed Denial of Service (DDoS) attacks. It’s was pretty successful with just 68 credentials. Have you changed your default credentials?

Tech Tip Tuesday - Check Yourself before You DDoS Someone Else

Internet of Things (IoT) devices (e.g. IP cameras, DVRs, refrigerators, etc) were to blame for the Distributed Denial of Service (DDoS) attack that knocked out most of the known Internet last week. Lifehacker has a good article and link to a tool that will tell you if devices on your network are part of the problem.

Tech Tip Tuesday – Distributed Denial of Service (DDoS) Attacks

Generating successful a DDoS attack is easier than it’s ever been and 2015 1st quarter reports seem to agree with that sentiment. The most common attacks have leveraged reflection amplification of Network Timing Protocol (NTP), Simple Service Discovery Protocol (SSDP) and Domain Name System (DNS). If you or your organization does not provide this service, you should block them from entering your network. You can use sites like What’s My IP to find out if your SSDP is showing.
