Intel VISA Exploit Offers Entry to Laptop’s Total Information, Researchers Present

Safety researchers have found a beforehand unknown characteristic within the Intel chipsets, which might permit an attacker to intercept knowledge from the pc reminiscence. The characteristic referred to as Intel Visualization of Inner Alerts Structure (Intel VISA) is alleged to be a utility that’s bundled by the chipmaker for testing on the manufacturing strains. Though Intel does not publicly disclose the existence of Intel VISA and is extraordinarily secretive about it, the researchers had been capable of finding a number of methods to allow the characteristic on the Intel chipsets and seize the info from the CPU.

As a per presentation made by the researchers Mark Ermolov and Maxim Goryachy of Constructive Applied sciences on the ongoing Blackhat Asia 2019 convention in Singapore, their exploits of the Intel chipsets do not require any modifications or particular tools. One of many strategies shared by the researchers concerned vulnerabilities detailed in Intel-SA-00086 advisory that give entry to Intel Administration Engine (Intel ME), in flip serving to allow VISA. Entry to Intel VISA makes the pc’s total knowledge weak and obtainable for the attacker.

Intel underplayed the exploit and informed ZDNet that the VISA subject requires bodily entry to the machines and the Intel-SA-00086 vulnerabilities have already been mitigated. The researchers nonetheless disagreed with Intel’s feedback and reportedly stated in an internet dialogue that the patched Intel firmware might be downgraded utilizing Intel ME, making the chipset weak and opening the door for accessing Intel VISA.

Mark Ermolov additionally famous that the vulnerabilities detailed in Intel-SA-00086 are simply one of many methods to entry VISA, and there are different strategies as nicely, together with Orange Thriller and Intel JTAG password. The technical particulars of those exploits might be discovered within the presentation slides shared on Blackhat Asia web site.
