RSA, Z/Yen report open WiFi hot-spots used to send spam

Well, this is bad news. It seems one of the biggest bugbears for open Wifi hot-spots, ‘what if it’s used to spam’, may now be happening on a wide scale…

Unauthorized WLAN Connections Used to Send Spam (2 April 2003)

Data gathered from a wireless LAN (WLAN) honeypot showed that nearly 75% of intentional unauthorized connections made were used to send spam. (newsfactor.com)

The honeypots were set up in the City of London for 2 weeks, as default, open WLANs. This is the nearest I can come to a source. Both RSA Security UK and Z/Yen don’t list it on their press releases pages.

My thoughts: it could be the Jeem or Rewt spam-relaying trojans searching for open nets automatically, from infected machines. Strikes me that there wouldn’t be too many spammers war-driving around London, in person.

Thanks to Tony Earnshaw for forwarding it on from SANS NewsBytes…

SANS stuff is always interesting; those who care about their network and computer security should really subscribe – not to mention the SANS GIAC stuff.

The undermentioned is interesting to SA Talk.

    I am the Managing Director of The Z/Yen Group.

    I’m sorry you were unable to find the paper on our site: it is listed under research rather than press releases:
