And the blame for all the SIP.
With the release of another update OS X 10.11 El Capitan from hundreds of innovations and corrections, and the operating system has been a very interesting function - System Integrity Protection (SIP). Its mission is to ensure system security and integrity.
Essentially, SIP - a "sandbox" in which work all applications and third-party software, and access to the heart of OS X file system are only authorized Apple development, application, got the necessary signatures and updates.
Researcher and developer of companies SentinelOne found a nasty vulnerability in the system, OS X 10.11 El Capitan, using which the malicious code can bypass SIP-defense. The principle of viral software is as follows: increasing their privileges to administrator level, it is integrated into the "holy of holies" - the closed area of the file system, which can be accessed only proven SIP applications.
And it falls into the system by coming updates that have the necessary access and rights. Next - business equipment. The virus can bring any malicious code and integrate it into the system, requesting the administrator password. Users will also be thinking that sets the next update, which requires a password confirmation.
What do users? On the issue of existing Apple has informed. The latest version of OS X 10.11.4 El Capitan partially closes a security hole, but confirming that the virus can not penetrate the SIP function - the researchers are not allowed.
The only thing we can do, as users - to regularly update the system to the latest version to date. And if you have still not done - it is strongly recommended to look into the store Update Mac App Store applications.
