Hackers have gotten smarter, and in response, UT researchers began work in early October to make browsers safer and less susceptible to attacks from malicious programmers on phoney websites.
For the next five years, as part of a $3 million grant from the National Science Foundation, researchers from UT, the University of California San Diego and Stanford University will look into and devise solutions for browsers attacked by hackers with malicious intent, said principal investigator Hovav Shacham.
“Right now, our biggest problem is that attackers have gotten better,” said computer science professor Shacham. “Attackers have understood that they really need to attack browsers. … It’s really mostly in browser exploits. Attackers are winning right now, and that’s a little unfortunate.”
Shacham said attackers are able to harm a user’s browser by exploiting the search engine’s bugs, which can be done through compromised websites. When a user opens a malicious website, it causes their browser to run the attackers’ code, giving the hackers access to a user’s files, Shacham said.
Unlike other compilers, just-in-time compilers interpret the source code in real time while a user is browsing websites, Stefan said. Since the compiler sorts through a lot of code very quickly, Stefan said there could be bugs within the compiler that attackers can take advantage of and input code that wasn’t meant to enter the compiler.
To make this compiler more secure, the researchers will run formal verification on the compiler, Stefan said. Formal verification gives the browser an extra layer of security and protection because it proves that the compiler and the code it is running is secure, Stefan said.
“Suddenly you can write your code as you would and there’s something checking that you did the right thing,” Stefan said. “It’s essentially having guardrails every time you drive.”
Shacham said the researchers will work with the browser Mozilla Firefox. Shacham said the goal of this project is to make it easier and safer for people to browse the internet without having to worry about whether they will be attacked.
“What motivates me is I want users to be safe online,” Shacham said. “I want, for now, the web platform to be such that people can click on links and not have to think twice about, ‘Is the thing on the other end a watering hole site set up by a foreign government to try to compromise my computer?’”
