Open Sesame: Although Microsoft is reportedly trying to make Windows 10 safer, there are bugs in some features that make the life of hackers very easy.
A new thing called Open Sesame allows hackers to run malicious code on a Windows 10 computer using only their voice.
The error is in the Cortana digital assistant and revealed by a team of researchers at the Black Hat conference in Las Vegas.
Researchers report that with this bug anyone could gain access to sensitive files, connect to malicious sites, download and execute infected files, and gain increased privileges (administrator level) on a locked computer.
All this can happen because the Windows 10 UI allows applications to run in the background while the computer is locked. So without having to access the mouse or keyboard of the device, the Cortana digital assistant can run several processes.
Security researchers Amichai Shulman, Tal Be'ery of Kzen Networks and Ron Marcovich and Yuval Ron of the Israel Institute of Technology discovered the flaw and reported it to Microsoft in April, according to a report by ThreatPost (Black Hat 2018: Cortana Flaw Allowed Takeover of Locked Windows 10 Device).
The Open Sesame error has already been documented by the code name CVE-2018-8140 and Microsoft reports that no exploit has yet been disclosed.
The flaw exists in Windows 10 Fall Creators Update (build 1709) and April 2018 Update (build 1803).
Open Sesame, What can you do? Updates are already running, so just let your system know.
