Apple Inc. has been trying to protect its Mac personal computer chain from a form of piracy that is very difficult to detect, but has not been successful in providing reforms to its customers, a security firm said on Friday.
Duo security said in a statement that it had checked what is known as firmware on Mac's personal computers. Firmware is known as a compact type of software that is more basic than the same operating systems, such as Microsoft Windows and Mac OS.
It is also indicated that the firmware is responsible, when running the PC each time and before the operating system is loaded, to check for the existence of the basic components of the device, such as the processor, RAM and RAM. So malware on the firmware is difficult to monitor.
In most cases, it is difficult to update the firmware with the latest security fixes, because the way they are installed is quite different from other updates, as they should be installed separately from the most common operating system updates.
In 2015, Apple began assembling firmware updates along with Mac operating system updates in an effort to ensure that the firmware remains updated to the latest version. However, Duo tested 73,000 Macs currently working, and found that 4.2 percent did not install the updated firmware update. In some models, such as the iMac with a 21.5-inch screen released in late 2015, % Of devices did not update their firmware.
The company said that not updating the firmware leaves many Mac devices vulnerable to attacks such as Thunderstrike attack, where hackers can control the Mac after connecting an Ethernet adapter in the port, "Thunderbolt" Apple.
"Apple continues to work hard on firmware security, and we're always exploring ways to make our systems more secure," Apple said. "In order to provide a safer and more secure experience in this area, the latest version of Mac OSH Hai Sierra automatically checks the Mac firmware for a week."
