A 'zero-day' bug discovered in the latest version of Mac OS X has been exploited by real-world malware before Apple has been able to release a patch.
The problem, revealed in public last month by security researcher Stefan Esser, relates to features designed to log errors introduced in OS X 10.10. The code lacks safeguards that would prevent hackers being able to create files with destructively wide-ranging privileges, anywhere in the OS. If exploited, the flaw known as 'DYLD_PRINT_TO_FILE' would give hackers the ability to install anything on an OS X system without using a password, opening up seemingly endless types of potential fraud.
At the time it was released, the exploit was purely hypothetical. Not any more: Malwarebytes reports the flaw has already been exploited for real.
In a blog post Malwarebytes' Adam Thomas claims to have discovered a malicious installer that was able to install VSearch and MacKeeper junk programs without needing a password. 'This is obviously very bad news,' he writes. 'Unfortunately, Apple has not yet fixed this problem, and now it is beginning to bear fruit.'

Let’s face it, shopping for the perfect gift for friends and family members can be stressful. Everyone has at least one hard-to-shop-for person in their life, so you can never have too many unique gift ideas. Ansar1.info was injected by Wild Neutron in 2013. Back in 2013, the attackers also leveraged a Mac OS X backdoor, known as OSX/Pintsized. This is also described in more detail in Eric Romang’s excellent blog. The same backdoor, compiled for Win32, is still being used in the 2015 attacks. Use-after-free vulnerability in the BitmapData class in the ActionScript 3 (AS3) implementation in Adobe Flash Player 13.x through 126.96.36.1992 on Windows and OS X, 14.x through 188.8.131.52 on Windows and OS X, 11.x through 184.108.40.2061 on Linux, and 12.x through 220.127.116.11 on Linux Chrome installations allows remote attackers to execute arbitrary.
The hope among researchers was that Apple would be able to fix the bug before the hackers used it. Esser even released his own kernel extension to protect against the attacks, though installing that comes with obvious risks.

Esser incurred criticism for releasing the news, because reports suggest he did not tell Apple before making the release public, as is standard amongst security researchers. Esser has rejected the criticism, saying that Apple should be blamed, not himself for simply releasing news of the bug.
As it turns out, Apple knew about the flaw already -- another researcher had clued them in and not made it public -- and the exploit does not work in beta versions of OS X 10.11, suggesting a fix is on the way for other versions of 10.10. As of now, though, any OS X user remains vulnerable. 'Worse, there is no good way to protect yourself, short of installing Esser's software to protect against the very flaw that he released into the hands of hackers worldwide, which introduces some serious questions about ethics and conflict of interest,' Thomas writes. 'Hopefully, this discovery will spur Apple to fix the issue more quickly.'
Apple has not yet commented on the bug, but we will update this post when a fix has been released.
- 7.2 Mac OS X El Capitan VS Windows 10
Both Mac OS X El Capitan and Windows 10 have become the new big things as far as computer operating system is concerned. Apple is the brain behind Mac OS X El Capitan, while Microsoft is the brain behind Windows 10 and both operating systems can compare side by side in so many ways.

Comparison: Mac OS X El Capitan VS Windows 10
Radium 3 1 1 – multi network radio player. Windows 10 is available in Beta version already and will be launched to the public in July 2015, however the new Mac OS X El Capitan will not be launched until the Fall season of 2015. Like Windows 10, Mac OS X El Capitan will also launch once, and globally- this means that users should prepare to get the Mac OS X El Capitan between September and October of 2015.

|OS X El Capitan has restriction on a number of upgrades or third party software you can install. Apple also provide a 6-digit code and two-factor security systems that make the Mac OS X El Capitan more secure.||Security||Windows 10 has been adjudged as the most secured Windows version ever. The in-built Antivirus in Windows 10 make it more immune to viruses, however, the leaky old windows OS may still make your computer vulnerable to some security attacks.|
|Mac OS X El Capitan maintains great stability and speed. Only pre-approved software can be installed on Mac OS X El Capitan but the advantage is that it saves you time and money when choosing from a wide range of software.||Performance||In terms of software support, Windows 10 has more third party software supports than Mac OS X El Capitan, and the upgrade to Windows 10 allows most older programs to continue to work after the upgrade. When it comes to playing Games, Windows 10 will always have an edge. Windows 10 comes with more games to choose from.|
|Apple has made its new Mac OS X El Capitan more secure, more curated and enhanced, but the use of third party software remains limited.||The Verdict||Windows provide more choices, better gaming and better user-interface, but you will spend more time searching for updates.|
