Gone are the days when Mac OS X was regarded as secure and not a target for malicious code. Hackers are actively exploiting a privilege-escalation bug in the latest edition of Mac OS X caused by new error-logging features added to that version ( 10.10.4 ).
The issue is serious enough that it allows drive-by attacks not requiring system passwords, and installs malware.
As if this isn’t bad enough, a sequel to a firmware injection malware developed earlier this year, has just been released and it hitchhikes on Thunderbolt peripherals to infect the MAC these peripherals are connected to at boot time.
Grrrr
