It appears a bug – named “DYLD” – is threatening Macs. Apple technicians are reportedly already working on it.
These appear to be busy days for Apple’s security system technicians.
In fact, according to The Guardian’s digital edition, a vulnerability affecting Mac machines has reportedly been discovered and isolated.
It concerns a bug known as DYLD, which, once activated on a PC, would allow its “sender” to gain unrestricted access to the machine.
This would happen because this bug could allow – via a program external to the Mac environment – full control of the system, effectively replacing the system administrator.
The result is clear: personal data at risk; programs that can be launched externally; obvious and evident vulnerability.
The “DYLD” bug, therefore, would manage to entirely bypass Mac’s security system, since – by effectively becoming a system administrator – it would no longer need the system password to be entered.
A rather dangerous threat that – again according to Guardian journalists – is recognized because it has already been exploited, meaning it is already in operation. The infection vector would be via email or through specially infected web pages capable of delivering the malicious code.
However, the same online publication specifies that Apple technicians are already well underway with resolving the issue, so much so that a definitive patch to fix the problem, isolate the bug, and “disable” it is reportedly almost complete.
The threat can therefore be eliminated thanks to Apple’s next official update for Mac, the release of which is expected in the coming days.
This will be the Mac OS X 10.10.5 system update, rolling out automatically shortly.
