HDX - Omni Botnet

Vulnerability Summary

The “Omni” botnet is a network of computer systems that have been infected with malicious software and controlled as a group without the systems owners’ knowledge.  Polycom HDX endpoints that are running software versions older than 3.1.12 contain security vulnerabilities that have been previously listed on the Polycom Security Center. These security vulnerabilities may render HDX endpoints vulnerable to takeover by the Omni botnet.  

To determine if an HDX is infected with the Omni botnet, or has been exploited by known vulnerabilities in older versions of HDX software, perform the following steps:

  • Login to the HDX web UI
  • Go to the “diagnostics” tab
  • Click on “download logs”
  • Click on “download support information package”
  • Your browser will download a file named “polycom_info...tgz”.
  • Uncompress this file, this will result in several files whose names start with “messages”
  • Examine these files for the occurrence of this string: ${IFS} (without spaces)

If ${IFS} appears in any log files, the HDX has been exploited by a known vulnerability in old HDX software, and the HDX should be factory reset and updated to 3.1.12 as soon as possible.
