Macs OS X vulnerable to permanent backdooring?

OSX permanent backdooring?

Macs older than a year are vulnerable to exploits that remotely overwrite the firmware that boots up the machine, a feat that allows attackers to control vulnerable devices from the very first instruction.

The attack, according to a blog post published Friday by well-known OS X security researcher Pedro Vilaca, affects Macs shipped prior to the middle of 2014 that are allowed to go into sleep mode. He found a way to re-flash a Mac's BIOS using functionality contained in userland, which is the part of an operating system where installed applications and drivers are executed. By exploiting vulnerabilities such as those regularly found in Safari and other Web browsers, attackers can install malicious firmware that survives hard drive reformatting and re-installation of the operating system.

Survey says businesses taking months to fix vulnerabilities

ticking time bomb?

On average, nearly half a year passes by the time organizations in the financial services industry and the education sector remediate security vulnerabilities, according to new research from NopSec.

For the study, the security firm analyzed all the vulnerabilities in the National Vulnerability Database and then looked at a subset of more than 21,000 vulnerabilities identified in all industries across NopSec's client network, Michelangelo Sidagni, NopSec Chief Technology Officer and Head of NopSec Labs, told SCMagazine.com in a Tuesday email correspondence.

According to the findings, organizations in the financial services industry and the education sector remediate security vulnerabilities in 176 days, on average. Meanwhile, the healthcare industry takes roughly 97 days to address bugs, and cloud providers fix flaws in about 50 days.
