At the beginning of 2018, intel ever was exploded to give flaw of CPU of two groups of minatory huge: Meltdown (fusing) with Spectre (ghostliness) . And in light of the safe announcement that answers a center to release according to 360 networks safety, these two groups of flaw can cause CPU to run the user information on the mechanism to divulge.
At that time, once two groups of flaw are announced suffer incidence extremely wide, and regard home as the biggest safe firm, the response rate of 360 can use glyph of fast " of a " to allow only: 360 safe bodyguard take the lead in rolling out tool of immunity of first flaw of domestic, 360 browsers upgrade quickly defend function, make a money can defence the homebred browser of flaw of this series CPU.
So, "What is ghostliness " of fusing " and " after all? How should we defend?
"Ghostliness " hits out, does safety defend also by " fusing " ?
Distinguish at the operating system or software flaw, "Flaw of ghostliness " of fusing " and " appears in CPU ground floor, it is by computer CPU design flaw is caused. Pass this group of flaw, even if is program of the prevailing in the computer, can have the limits of authority of " sovereign " .
Among them, "Fusing " can use CPU to design the medium kernel data in forecasting executive character to get user order, this protects a mechanism with respect to what broke core memory directly, baleful code can visit sensitive memory directly; And flaw of " ghostliness " is passed distort the memory of other application process, cheat them to visit the address of core memory, the menace that this serves a provider to the cloud is bigger.
At that time flaw explodes after going out, because amount of Intel CPU user is great, the Intel CPU that produced 1995 is almost all " lies gun " . Later, include Linux, windows, the operating system platform that waits inside participated in OSX repair, foreign Firefox, chrome, the browser such as Edge also released relevant safe announcement gentle to see plan, 360 browsers also roll out for a short while upgrade version, become domestic head money to support the browser product of defence CPU flaw.
Flaw is again terrible, also have method immunity it!
"After ghostliness " of fusing " and " is exposed to the sun to go out at that time, caused the panic inside global limits for a time, because they may let themselves at any time,turn " into transparent person " -- the Zhang date that stores in computer or browser, password, mailbox waits privacy information a moment to will face the risk that divulge entirely.
Although Intel is seasonable later repair flaw, manufacturer of each operating system, browser is seasonable also follow-up, but still let a person sense fear after the event. If safe group did not discover these flaw in time, is the privacy of that user can all by aggressor purloin?
Nevertheless, broad now user need not worry about this problem surely. Recently, the 360 immune tools that rolled out flaw of an integrated and all Gao Wei, after the user downloads this tool, can leave not only ghostliness " of " fusing " and " , still can blackmail virus, rift valley with immunity flaw, double kill flaw to wait, the network safety problem that one key solves these tall danger flaw to may be brought, need not swallow the fear that is controlled by flaw again.
