Data Communications
The Twitter session can be protected by using a pure OAuth exchange, without making use of Basic authentication, or by protecting the whole session with HTTPS.
Coincidentally, the discovery of these vulnerabilities was aligned with Twitter's announcement to increase the security of third-party apps: "Starting August 31, all applications will be required to use “OAuth” to access your Twitter account". This service switch didn't make any difference regarding this vulnerability, as HTC Peep still works through its OAuth capabilities. However, as this advisory demonstrate, technology must be implemented properly. Historically, Twitter developers have been able to choose one of two authentication methods: Basic Authentication or OAuth. Somehow, HTC Peep is using both methods simultaneously, exposing the user credentials.
Modern mobile devices implement multiple communication technologies, such as IrDa, Bluetooth, Wi-Fi, and mobile (2G/3G). The last two, Wi-Fi and 2G/3G, are the most commonly used methods to establish data communications from the mobile device to other entities. Therefore, this vulnerability can be exploited on targeted attacks when the mobile device is using any of these two technologies:
• Wi-Fi: When the mobile device connects to a Wi-Fi (802.11) network, an attacker can intercept all your web traffic if it is an open or WEP Wi-Fi network. If the network is based on WPA(2)-PSK, any user with access to that network can also collect all your traffic. You can protect your Wi-Fi data communications if you only connect to WPA2-Enterprise Wi-Fi networks (or, potentially, if you thoroughly make use of VPN technologies). Unfortunately, even when your device is not connected to any Wi-Fi network, still this vulnerability can be exploited in combination with other vulnerabilities, such as Karma-like attacks. See "TAD-2010-003: Full 802.11 Preferred Network List (PNL) disclosure in Windows Mobile 6.5".
• 2G/3G: When the mobile device connects to a mobile network (2G or 2.5G: GPRS or EDGE) an attacker can intercept all your web traffic. You can protect your mobile data communications if you only connect to +3G data networks. For more information see the "GPRS/EDGE Security" blog post and the recent "A practical attack against GPRS/EDGE/UMTS/HSPA mobile data communications" BlackHat DC 2011 Taddong presentation, by David and Jose.
Independently of the data network access used by the mobile device, at some point the web traffic will enter on the public Internet in the clear (unencrypted), where it can be intercepted by anyone with access to capture the traffic on any of the intermediate network segments between the mobile device and Twitter.

used to denote the network that transports management information
between a management station and the network entity (NE). This
definition of DCN is sometimes referred to as Management
