Earlier this week, Dr. Web reported the discovery of a Mac OS X botnet Flashback (Flashfake). According to their information, the estimated size of this botnet is more than 500, 000 infected Mac machines.

 

Our logs indicate that a total of 600 000+ unique bots connected to our server in less than 24 hours. They used a total of 620 000+ external IP addresses.

 

More than 50% of the bots connected from the United States.

The scariest thing about the Flashback trojan: I have no idea how to fight it

The scariest thing about the Flashback trojan: I have no idea how to fight it | Apple, Mac, iOS4, iPad, iPhone and (in)security... | Scoop.it
The recent reemergence of the Flashback OSX trojan has shown a lot of things, but none more clearly than this: I have no clue how to counter virus and...

 

I remember telling friends and supervisors multiple times that if a major Mac virus or trojan were to emerge, I would be at a complete loss as to how to fight it. This is probably still true, as the emergence of the Flashback trojan has shown most clearly.

 

The most recent version of Flashback targets a unpatched Java vulnerability in OSX, one that Oracle fixed months ago but Apple never got around to relaying. Now, I’m still not entirely sure what Flashback does, but I was pretty completely clueless on how I could fight it. This is the bitter reality of being a Mac owner in 2012. I have very little idea of how to keep my machine safe.

 

And I imagine many other Mac owners feel the same way.

 

If the half million Flashback-infected Macs are any indication, ===> Mac owners are all going to need a crash course in computer safety. And fast. <===

Mac users 'just as easily duped by cybercriminals' as Windows users

Mac users 'just as easily duped by cybercriminals' as Windows users | Apple, Mac, iOS4, iPad, iPhone and (in)security... | Scoop.it
In the face of new threats aimed at OS X, a security expert has warned that Mac users may be even more vulnerable than Windows users.

 

Because Windows users are more likely to be running up-to-date anti-virus programs, Graham Cluley of Sophos says that many Mac users are missing a "valuable safety net".

 

In the face of several new threats targeting Mac OS X that have been discovered in recent weeks, Mac users should make sure that they have some form of protection, Cluley said. However, keeping your computer safe from cybercriminals isn't just a case of having anti-virus programs installed - it's about making sensible choices as well.

 

As we have seen on the Windows platform, the majority of the attacks do not exploit any weakness in the operating system but instead take advantage of the bug in people's brains.

 

===> Mac users can be just as easily duped as their Windows cousins into making poor choices, and could end up infected as a result, Cluley told Macworld. <===

 

Use antivirus programs!

Apple's security code of silence: A big problem

Apple's security code of silence: A big problem | Apple, Mac, iOS4, iPad, iPhone and (in)security... | Scoop.it
Security industry insiders have long known the Mac platform has its holes. The Flashback Trojan is the first in-the-wild issue that's confirmed this, and big-time. More will follow unless Apple steps up its game.

 

Apple has cultivated a myth about security on the Mac platform. The myth goes like this: Apple users don't need antivirus software. We're more secure than anything out there. Security worries are overblown.


In reality, Apple practiced security by obscurity with the Mac.


Those days may be ending in a hurry. Apple's relative silence about malware is going to have to end as the company finds itself managing a large ecosystem, noted ZDNet's Ed Bott.

 

Delivering massive security updates during product launches and software rollouts just isn't going to cut it.

New Mac malware epidemic exploits weaknesses in Apple ecosystem

New Mac malware epidemic exploits weaknesses in Apple ecosystem | Apple, Mac, iOS4, iPad, iPhone and (in)security... | Scoop.it
The nightmare scenario for Mac owners is here. At least 600,000 Macs worldwide have been infected, silently, by the Flashback virus.

 

What makes this outbreak especially chilling is that the owners of infected Macs didn’t have to fall for social engineering, give away their administrative password, or do something stupid.

 

All they had to do was visit a web page using a Mac that had a current version of Java installed.

 

Macs are not immune. For years Apple owners have been told that Macs don’t get viruses, but we know that’s not true.

 

And Apple’s casual approach to security updates makes them arguably more vulnerable to this sort of attack than other platforms.

Apple users will be suffering a crisis of faith, as it was revealed its faith-based security system failed to prevent over 600,000 Macs around the world from being compromised by the Flashback Trojan.

 

Apple has now released a patch that should squash the vulnerability. Whether or not Apple users will rush to protect their machines is another matter. Earlier this week, Sophos' Graham Cluley urged users to be vigilant. There had been a "flood of Mac malware activity" against users in mid-2011, with a steady stream since.


Users were encouraged to consider that many cyber attacks are not specifically technical, but rely on social engineering and human folly.


Apple fans would be "foolhardy" not to protect their Macs with anti-virus software and to keep it updated, Cluley said.

The infamous Flashback malware has successfully infected over half a million Mac computers according to Russian security firm Dr. Web.


Dr. Web reported on 4 April that the BackDoor.Flashback.39 had infected far more computers than researchers initially thought.
Nearly 300 are thought to be inside Apple's headquarters.


"Now BackDoor.Flashback botnet encompasses more than 550 000 infected machines, most of which are located in the United States and Canada," read Dr. Webs initial statement.
The figure has since increased with Dr. Web malware analyst Sorokin Ivan claiming on Twitter that the count has risen to 600,000.

Doctor Web exposes 550 000 strong Mac botnet
April 4, 2012

 

Doctor Web—the Russian anti-virus vendor—conducted a research to determine the scale of spreading of Trojan BackDoor.Flashback that infects computers running Mac OS X.

 

Now BackDoor.Flashback botnet encompasses more than 550 000 infected machines, most of which are located in the United States and Canada. This once again refutes claims by some experts that there are no cyber-threats to Mac OS X.

 

Systems get infected with BackDoor.Flashback.39 after a user is redirected to a bogus site from a compromised resource or via a traffic distribution system. JavaScript code is used to load a Java-applet containing an exploit.

 

Doctor Web's virus analysts discovered a large number of web-sites containing the code.
