Microsoft researchers have unveiled an anti-hacking concept that can help
track hackers or malicious content to origin servers.

The Host Tracker program's goal is to "de-anonymize the Internet" through
the ability to host servers with 99 percent accuracy.

Host Tracker is designed to unmask would-be hackers who take
advantage of anonymizing techniques by cross-referencing Internet
protocol traffic data to identify the true origin. Microsoft's
representatives said the Host Tracker system relies on
application-level events -- in this case, Internet Explorer browser
sessions -- to automatically infer host-IP bindings.

Researchers Yinglian Xie, Fang Yu and Martin Abadi ran
some initial tests by analyzing a month's worth of data from an e-mail
server, roughly 330 GB, to ascertain from the samples who may have been
responsible for sending out certain types of spam. They studied some
550 million user IDs and 220 million IP addresses, and matched time
stamps for message transmission or e-mail log-ons.

"The fact that we are able to trace malicious traffic to the proxy
itself is an improvement because we are able to pinpoint the exact
origin," Xie said (a PDF of the study can be found at
