Echobot launches widespread attack against IoT devices
Check Point’s researchers also report the Emotet botnet has been reactivated.

Check Point Research has published its latest Global Threat Index for August 2019. The Research team is warning organisations of a new variant of the Mirai IoT Botnet, Echobot, which has launched widespread attacks against a range of IoT devices.

First seen in May 2019, Echobot has exploited over 50 different vulnerabilities, causing a sharp rise in the ‘Command Injection Over HTTP’ vulnerability which has impacted 34 per cent of organisations globally.

August has also seen the Emotet botnet’s offensive infrastructure becoming active again, after it shut down its services two months ago. Emotet was the biggest botnet operating in the first half of 2019. Although no major campaigns have been observed as yet, it is likely that it will be used to start spam campaigns soon.

“Echobot was first seen in mid-May, and as a new variant of the notorious Mirai IoT Botnet it’s important to note the sharp increase in exploitations, as it is now targeting over 50 different vulnerabilities. Echobot has impacted 34 per cent of companies around the world, which shows how vital it is for organisations to ensure all patches and updates for their networks, software and IoT devices are applied,” said Maya Horowitz, Director, Threat Intelligence & Research, Products at Check Point.
