Websites have a new way to #spy on visitors: #analyzing their #SSD activity
source: arstechnica.com/security/2026/…
The #attack that #FROST uses is known as a contention side channel, which measures the interaction of various processes all using (or competing for) a given resource. By measuring the timing of certain I/O (input-output) operations of the SSD a #visitor is using, the researchers were able to determine the #websites open in other tabs—even on other browsers—and the apps that were open on the visitor’s device. FROST requires no interaction from the visitor other than opening the site hosting the attack.#news #web #www #browser #hardware #software #sidechannel #tracking #surveillance #privacy #internet #online #security #problem #computer #surfing #hack #hacker #software #cybersecurity
