BLOG: Remotely listen in via hacked VoIP phones: Cisco working on eavesdropping patch

Darlene Storm | Jan. 9, 2013
During Hacking Cisco Phones, the researchers demonstrated how they could remotely turn on a phone’s microphone and eavesdrop from anywhere in the world. If the VoIP Cisco phone has a web cam, they could also turn that on without anyone the wiser

The following models have reached end-of-life (EOL) status (for hardware only):

  • Cisco Unified IP Phone 7971G-GE
  • Cisco Unified IP Phone 7970G
  • Cisco Unified IP Phone 7961G
  • Cisco Unified IP Phone 7961G-GE
  • Cisco Unified IP Phone 7941G
  • Cisco Unified IP Phone 7941G-GE
  • Cisco Unified IP Phone 7906

Until a patch that closes the hole in the Cisco assigned "CSCuc83860 bug," thingp3wn3r workarounds include "Restrict SSH and CLI access to trusted users only. Administrators may consider leveraging 802.1x device authentication to prevent unauthorized devices or systems from accessing the voice network."
