Hello, I am wondering about the possibility of the wlan cards inside laptops being switch without the users knowledge into ad-hoc mode. How would I as a user detect that my wlan is in ad-hoc mode? I know that ad-hoc mode doesn't provide encryption. Would I be vulnerable to anyone in my area who is infected if in ad-hoc mode? If I am in ad-hoc mode, would I notice any difference when surfing? [guess]Pages would not open seemingly instantly, there would be a delay.[/guess] [Edit2]: Would I be able to surf while in ad-hoc mode? (This is the ? I wanted to ask above.) I believe the answer to this is yes. http://wifi.aximsite.com/alternate.html#_adhoc Surfing is possible on the system in ad-hoc mode using ICS to bridge the nic to the wlan.[/Edit2] With ad-hoc mode, would an attacker be able to re-aquire me, after I clean up, via an unsecure local router in my neibhorhood? Thanks, Searching_ _ _ edit: To do this remotely, I am guessing, they would need to be able to write to serial eeprom on the wlan, which normally uses parallel port programming to access. http://www.phanderson.com/printer/eeprom/eeprom.html But I have found that you can program hardware I/O ports using linux and C http://www.faqs.org/docs/Linux-mini/IO-Port-Programming.html At a glance, it may be possible to do it remotely.
