Attacking The Edges Of Secure Internet Traffic

Researchers have uncovered new ways that criminals can spy on Internet users even if they're using secure connections to banks, online retailers or other sensitive Web sites.

The attacks demonstrated at the Black Hat conference here show how determined hackers can sniff around the edges of encrypted Internet traffic to pick up clues about what their targets are up to.

It's like tapping a telephone conversation and hearing muffled voices that hint at the tone of the conversation.

The problem lies in the way Web browsers handle Secure Sockets Layer, or SSL, encryption technology, according to Robert Hansen and Josh Sokol, who spoke to a packed room of several hundred security experts.

Another popular talk at Black Hat concerned a new attack affecting potentially millions of home routers. The attack could be used to launch the kinds of attacks described by Hansen and Sokol.

Researcher Craig Heffner examined 30 different types of home routers from companies including Actiontec Electronics Inc. and Cisco Systems Inc.'s Linksys and found that more than half of them were vulnerable to his attack.

He tricked Web browsers that use those routers into letting him access administrative menus that only the routers' owners should be able to see. Heffner said the vulnerability is in the browsers and illustrates a larger security problem involving how browsers determine that the sites they visit are trustworthy.

The caveat is he has to first trick someone into visiting a malicious site, and it helps if the victim hasn't changed the router's default password.

Still: "Once you're on the router, you're invisible — you can do all kinds of things," such as controlling where the victim goes on the Internet, Heffner said.
