  • Warkitting: the Drive-By Subversion of Wireless Home Routers

    Warkitting: the Drive-By Subversion of Wireless Home Routers

    Warkitting: the Drive-by Subversion of Wireless Home Routers Alex Tsow Markus Jakobsson Liu Yang Susanne Wetzel School of Informatics Department of Computer Science Indiana University Stevens Institute of Technology Bloomington, IN 47408 Hoboken, NJ 07030 {atsow, markus}@indiana.edu {lyang, swetzel}@cs.stevens.edu Abstract In this paper we introduce the notion of warkitting as the drive-by subversion of wireless home routers through unauthorized access by mobile WiFi clients. We describe how such at- tacks can be performed, evaluate the vulnerability of currently deployed wireless routers based on experimental data, and examine the impact of these attacks on Internet fraud. Our analysis shows that it is possible in practice to carry out warkitting attacks with low cost equipment widely available today and that the volume of credential theft possible through warkitting ex- ceeds current estimates of credential theft due to phishing. We discuss how to detect a warkit- ting attack in progress and show how to analyze warkitted routers for evidence linking it to the attackers. Keywords: Warkit, WAPkit, WAPjack, wireless home routers, phishing, pharming, Internet fraud, intrusion detection 1 Introduction The convenience of wireless networking has led to widespread adoption of wireless access points in home and small business settings. While some wireless access points are administered by se- curity conscious users, several recent studies show that a large number of wireless access points run with default settings. The default settings from the most established vendors are optimized for ease of setup instead of secure access. Most commonly, the default settings disable wireless en- cryption, permit wireless access to router administration, and guard administration with published passwords.

(2005). Taxonomy of WRT54G(S) hardware and custom firmware. In Proceedings of 3rd Australian Information Security Management Conference (pp. 1-10). Edith Cowan University. Available here This Conference Proceeding is posted at Research Online. https://ro.ecu.edu.au/ecuworks/2946 Taxonomy of WRT54G(S) Hardware and Custom Firmware Marwan Al-Zarouni School of Computer and Information Science Edith Cowan University E-mail: [email protected] Abstract This paper discusses the different versions of hardware and firmware currently available for the Linksys WRT54G and WRT54GS router models. It covers the advantages, disadvantages, and compatibility issues of each one of them. The paper goes further to compare firmware added features and associated filesystems and then discusses firmware installation precautions and ways to recover from a failed install. Keywords WRT54G, Embedded Linux, Wireless Routers, Custom Firmware, Wireless Networking, Firmware Hacking. BACKGROUND INFORMATION The WRT54G is a 802.11g router that combines the functionality of three different network devices; it can serve as a wireless Access Point (AP), a four-port full-duplex 10/100 switch, and a router that ties it all together (ProductReview, 2005). The WRT54G firmware was based on embedded Linux which is open source. This led to the creation of several sites and discussion forums that were dedicated to the router which in turn led to the creation of several variants of its firmware.

Due to the large deployment of the WLAN, the immediate need of management plat­ forms has been recognized, which has a significant impact on the performance of a WLAN. Although there are various vendor-specific and proprietary solutions available in the market to cope with the management of wireless LAN, they have problems in interoperability and compatibility. To address this issues, IETF has come up with the interoperability standard of management of WLANs devices, Control And Provisioning of Wireless Access Points (CAPWAP) protocol, which is still in the draft phase.

    The Internet and World-Wide-Web: Potential Benefits to Rural Schools

    DOCUMENT RESUME ED 401 064 RC 020 760 AUTHOR Barker, Bruce O. TITLE The Internet and World-Wide-Web: Potential Benefits to Rural Schools. PUB DATE Oct 95 NOTE 9p.; Presented at the Annual Conference of the National Rural Education Association (87th, Salt Lake City, UT, October 4-8, 1995). PUB TYPE Speeches/Conference Papers (150) Information Analyses (070) Viewpoints (Opinion/Position Papers, Essays, etc.) (120) EDRS PRICE MF01/PC01 Plus Postage. DESCRIPTORS *Access to Information; *Computer Networks; *Computer Uses in Education; *Educational Benefits; Electronic Mail; Elementary Secondary Education; Gateway Systems; Information Networks; *Internet; *Online Systems; Rural Schools; World Wide Web IDENTIFIERS National Information Infrastructure ABSTRACT The Internet is a decentralized collection of computer networks managed by separate groups using a common set of technical standards. The Internet has tremendous potential as an educational resource by providing access to networking through worldwide electronic mail, various databases, and electronic bulletin boards; collaborative investigation across geographic and political boundaries; and a wide range of resources that can be used at times convenient to the user. The Internet's resources can be grouped into three categories: messaging, which includes e-mail and discussion groups; remote login, which permits a user to access another computer's information; and file exchange, the transfer of information accessed from another computer to the user's computer. The Internet can benefit small rural schools by providing access to the same information heretofore available only to affluent schools. Drawbacks include slow access, the "additive" nature of the Internet, and the fact that the Internet is uncensored. Some schools have policies that permit access to controversial information only when permission is granted and the purpose and educational value have been identified.
