However, there are some concerns related to clear text data transmission over wireless networks that results in a number of attacks including Sniffing, ARP Poisoning, and Man-In-The-Middle. On one hand, a number of research focuses on countermeasures. On the other hand, some research focuses on exploring new vulnerabilities in wireless networks but it can detect with IDS. In this paper, we introduce a new technique that is considered as a stealth attack for web user over wireless networks. The proposed technique creates a crafting spoof web content and sends it to a user before the geniune web content from a website is transmitted to the user. This technique can avoid detection of existing IDS. We also suggest a countermeasure against the proposed technique.Mahidol UniversityComputer ScienceConference PaperSCOPUS10.1109/ISCIT.2014.7011911
