In October, two security experts at hacker conference ToorCon9 in San Diego hacked into their hotel’s corporate network using a Cisco VoIP phone<\/strong><\/font><\/p>\n

Cisco confirmed it is possible to eavesdrop on\u00a0remote conversations using Cisco VoIP phones. In its <\/font>security response<\/font><\/a>, Cisco says: “an attacker with valid Extension Mobility authentication credentials could cause a Cisco Unified IP Phone configured to use the Extension Mobility feature to transmit or receive a Real-Time Transport Protocol (RTP) audio stream.”<\/font><\/p>\n

Cisco adds that Extension Mobility authentication credentials are not tied to individual IP phones and that “any Extension Mobility account configured on an IP phone’s Cisco Unified Communications Manager\/CallManager (CUCM) server can be used to perform an eavesdropping attack.”
\n<\/font>
\nThe <\/font>technique was described<\/font><\/a>\u00a0by Telindus researcher Joffrey Czarny at HACK.LU 2007 in Luxembourg in October.
\n<\/font>
\nCisco has published some workarounds to this problem in its <\/font>security response<\/font><\/a>.
\n<\/font>
\nAlso in October, two security experts at hacker conference ToorCon9 in San Diego hacked into their hotel’s corporate network using a Cisco VoIP phone.
\n<\/font>
\nThe hackers, John Kindervag and Jason Ostrom said they were able to access the hotel’s financial and corporate network and recorded other phone calls, according to a <\/font>blog on Wired.com<\/font><\/a>.
\n<\/font>
\nThe hackers used penetration tests propounded by a tool called VoIP Hopper, which mimics the Cisco data packets sent at three minute intervals and then trades a new Ethernet interface, getting the PC \u2013 which the hackers switched in place of the hotel phone \u2013 into the network running the VoIP, according to the <\/font>blog post<\/font><\/a>.
\n<\/font>
\nThe Avaya configuration is superior to Cisco, according to the hackers, because you have to send requests beyond a sniffer. Although it can be breached the same way, by replacing the phone with a PC.<\/font><\/p>\n","protected":false},"excerpt":{"rendered":"
