Early on September 18 a message, f-Secure of Internet security company discovered a new loophole, this flaw may allow a hacker to add close hard disk in the visit below computer Morpheus mode.
F-Secure shared the detailed information of concerned flaw in rich guest article. The safe researcher rediscovery of F-Secure cold start-up attack, this flaw affects almost all computer to include machine of table computer, an organic whole and jotter, its biggest question is the equipment filch that the hacker that allows physics to visit facility uses this flaw to be decided from the lock sensitive information. Use cold start-up filch to save the data in computer memory, the part is sensitive after because the computer is in,restarting forcibly information will be brief keep existence memory in. However, good news is, attack cannot be carried out remotely, need physics visits facility.
Cold start-up is a kind of of computer means that start. Cut off the power source of computer namely, start afresh, once cold start-up, the thing of memory is all and missing, detect afresh hardware, enter CMOS, depend on the operating system that start again.
Do not have a patch at present can the loophole with new rehabilitate, researcher suggests to adjust a setting to make the computer automatic after shutting screen close machine or dormancy, is not to enter Morpheus mode.
Below Morpheus mode, in memory still power supply, all data are maintaining. Power comsumption is very right now low, can restore quickly. And below dormancy mode, data also in store, in saving hard disk nevertheless, at this moment power source can be cut off, be equal to and close opportunity is same, can regain the working position to the front of dormancy afresh when restore nevertheless.
F-Secure still points out, as a result of it need is visited and operate hardware, all brands get the influence of flaw. F-Secure has connected cicada to include Dai Er, apple, associate and Microsoft inside all suppliers. However, the MacBook that Apple claims to deploy T2 chip does not suffer the effect of this flaw.
