The researchers have successfully leveraged iLeakage to recover YouTube viewing history, the content of a Gmail inbox-when a target is logged in-and a password as it’s being autofilled by a credential manager. When visited by a vulnerable macOS or iOS device, the website uses JavaScript to surreptitiously open a separate website of the attacker’s choice and recover site content rendered in a pop-up window. The researchers implement iLeakage as a website. The nearly endless stream of exploit variants has left chip makers-primarily Intel and, to a lesser extent, AMD-scrambling to devise mitigations. The side channel in this case is speculative execution, a performance enhancement feature found in modern CPUs that has formed the basis of a wide corpus of attacks in recent years. ![]() ![]() ![]() It does, however, require extensive reverse-engineering of Apple hardware and significant expertise in exploiting a class of vulnerability known as a side channel, which leaks secrets based on clues left in electromagnetic emanations, data caches, or other manifestations of a targeted system. Further Reading Intel SGX is vulnerable to an unfixable flaw that can steal crypto keys and moreiLeakage, as the academic researchers have named the attack, is practical and requires minimal resources to carry out.
