The number of Mirai scanner systems across the world decreased slightly from December 2017 to June 2018. There is less concentration of scanner systems in North America, South America, and Asia in June 2018 versus December 2017. Europe is the only region where Mirai scanner infections remained relatively the same from December 2017 to June…
Read MoreIoT attacks, budget shortfalls, and the skills gap are among the problems keeping security pros up at night. The world of cybersecurity gets more intriguing every year. In 2017, security professionals saw their share of attacks, but the increasing sophistication of the skirmishes is notable — with almost machine-like weaponization of code on the attackers’…
Read MoreStep 3: Investigate the State of IoT Usage within Your Organization Never believe what you’ve been told or your own assumptions. You need to find out for yourself what IoT devices are already in use within your environment. It’s dangerously naïve to assume there aren’t any in place already. Just like standard IT security risk…

That’s the kinda thing an idiot would have on his luggage!)” Top Attacked Username and Password Pairs: Credentials Every security team should make it a priority to ensure that…
Read MoreWhat is the Problem with IoT Security? Security guru Dan Geer notes that the cybersecurity industry came of age with the introduction of Windows 95 and its built-in TCP/IP stack. Suddenly every home computer was on the Internet in a world “where every sociopath is your next-door neighbor.” These home computers were poorly administered by…
Read MorePoor security is another clue that young novices are operating botnets. The Owari authors left their command and control (C&C) MySQL database wide open (port 3306), “protected” with both the username and password of “root.” Control of IoT devices is a highly competitive market, where rivals commonly DDoS each other. In one case, a competing…
Read MoreF5 Networks researchers have detected a new variant of the “Echobot” malware, now consisting of 71 exploits. The authors continue to follow the trend of arming the malware and for the threat group to expand its operation. These newly added exploits target both old and new vulnerabilities, adding as new ones target industrial control system…
Read MoreConclusion This latest Gafgyt campaign shows that the malware is evolving and taking on techniques used by other malware authors. Those interested in building botnets don’t need to go far in order to find source code to create their own. Botnets for service are also common and easy to buy. They are advertised on a…
Read MoreImagine not being able to escape online surveillance. The Internet of Things (IoT) is composed of technology that optimize our lives and is deployed in the thousands. However, the convenience these devices add to our lives comes at a cost—privacy. In 2019, China had more than 960 million IoT devices, many of them surveillance cameras, making…
Read MoreMirai is an IoT botnet (or thingbot) that F5 has discussed since 2016. It infamously took down large sections of the Internet in late 2016 and has remained active ever since. Its source code was released online in September 2016, allowing unskilled attackers to create a malicious botnet with relative ease. Mirai continues to target…
