University researchers in the US have developed a new fingerprint capturing and browser spoofing attack called Gummy Browsers.
The 'Gummy Browsers' attack is the process of capturing a person's fingerprint by making them visit an attacker-controlled website and then using that fingerprint on a target platform to spoof that person's identity.
Browser setting and debugging tool - Both can be used to change the browser attributes to any custom value, affecting both the JavaScript API and the corresponding value in the HTTP header.
"Our results showed that Gummy Browsers can successfully impersonate the victim's browser transparently almost all the time without affecting the tracking of legitimate users," the researchers explain in an Arxiv paper published yesterday.
"Since acquiring and spoofing the browser characteristics is oblivious to both the user and the remote web-server, Gummy Browsers can be launched easily while remaining hard to detect".
The researchers state that threat actors can easily use the Gummy Bear attack to trick systems utilizing fingerprinting.
