Data Breaches Tracker monitor unsecured ElasticSearch servers online

Cybersecurity research at WizCase, an online security and privacy portal, built a tool to track accessible ElasticSearch servers on the internet. 

Cybersecurity research at WizCase, an online security and privacy portal, developed a tool that allows track accessible ElasticSearch servers on the Internet.
The tool scans the web for accessible ElasticSearch servers and displays different variables such as the total number of running Elasticsearch instances, a breakdown of secure vs insecure servers and more.  

More specifically – the tool is tracking the number of servers attacked by “Meow,” interestingly the experts noticed a quite significant rise in the number of servers wiped the first week of March. According to the experts over 2500 servers have been erased within a few days. 

As it’s always hard to figure out the amount of data exposed due to misconfiguration, here the tool: https://www.wizcase.com/tools/data-breaches-tracker/.

A recent scan performed on March 15th, 2021 provided the following results:

• Total number of Servers Scanned 334,013
• Total number of Running instances 9,202
• Total number of Servers accessible without authorization 5,740
• Total size of Servers accessible without authorization 9 TB
• Total number of Records exposed in servers accessible without authorization17,830,145,680
