Skype Trojan can log VoIP conversations


www.pcauthority.com.au

Security giant Symantec claims to have found the public release of source code for a Trojan that targets Skype users.

Trojan.Peskyspy is spyware which records a voice call and stores it as an MP3 file for later transmission.

An infected machine will use the software that handles audio processing within a computer and save the call data as an MP3. The file is then sent over the internet to a predefined server where the attacker can listen to the recorded conversations.

I guess hackers finally came up with a solution that the NSA couldn't! It was only a matter of time for Skype.

Unfortunately, with Skype you can't even use Strong Encryption for VoIP, like Zfone. Skype uses a closed proprietary protocol, which they do not publish. Skype intentionally does not interoperate with the rest of the VoIP industry.

There is another problem with Skype. It uses a Variable-Bit Rate codec, which introduces significant vulnerabilities, regardless of the quality of encryption. (Google Talk and Gizmo are vulnerable to this as well!)

Johns Hopkins University researchers have observed that when voice is compressed with a variable bit-rate (VBR) codec, the packet lengths vary depending on the types of sounds being compressed. This leaks a lot of information about the content even if the packets are encrypted, regardless of what encryption protocol is used.

Breaking VoIP Encryption.

Language Identification of Encrypted VoIP Traffic

If you value your Telephony Privacy, then use a VoIP solution that doesn't use Variable Bit Rate, but uses Constant Bit Rate instead, and use one that allows you to use Strong Encryption like Zfone in addition to it. That way, your VoIP Calls will remain private from the prying ears of Script-Kiddies, Hackers and the NSA!
