Flashback malware appears to have infected computers in Apple's HQ...

 

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.

Russian researchers have discovered a botnet of more than 600,000 Macs. Yes, Macs -- you know, those things that don't get malware. Apple (NASDAQ:AAPL) is coming under heavy criticism for its slow response to known vulnerabilities and for perpetuating the myth that OS X is malware-free.

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!

Java update for OS X patches Flashback malware exploit

Java update for OS X patches Flashback malware exploit | Apple, Mac, iOS4, iPad, iPhone and (in)security... | Scoop.it

Apple responds to Flashback malware development with a Java update in less than a week. 

 

Following the recent Flashback malware developments for OS X where unpatched vulnerabilities in the latest Java runtime for OS X were being exploited, Apple has issued an update that brings Java up-to-date and patches these vulnerabilities.


The patch is available via Software Update for systems that have Java installed, but can also be downloaded from the following Apple support Web pages. The update is available only for OS X 10.6 and 10.7, since Apple has stopped supporting prior versions of OS X.

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.

Apple updates Java after malware spreads

Apple updates Java after malware spreads | Apple, Mac, iOS4, iPad, iPhone and (in)security... | Scoop.it
Enterprise users of Java for the Mac OS X should ensure their machines are updated with the latest security patch from Apple, released Tuesday.

 

The update, for both Lion (10.7.3) and Snow Leopard (10.6.8) versions of the platform, closes a dozen holes in Java 1.6.0_29, "the most serious of which may allow an untrusted Java applet to execute arbitrary code outside the Java sandbox," according to Apple.

 

That presumably refers to CVE-2012-0507, which researchers at F-Secure said Monday was being used to spread the latest variant of the password-stealing Flashback trojan.
