Windows has been the target of malware for decades. This has resulted in a more hardened system and a better user awareness.

On the other hand, OS X has not really needed to go through all the troubles of crime fighting until recently.

===> Now, with its growing market share and lower user awareness, it is clear that OS X is becoming more and more attractive to malware authors. <===

Apple said Tuesday it's developing a solution to combat the Flashback malware that experts say has infected around 600,000 Mac computers around the world.

The explosion in development and adoption of smartphones and tablets for both personal and business use in the past two years is both a blessing and a curse to IT departments globally.

Known as the Bring Your Own Device (BYOD) phenomenon, on one hand, there is an opportunity for greatly increased productivity and decreased costs.

===> On the other, there are increased security risks, management issues and even data and device ownership and governance issues. <===

Kaspersky Lab -- which is offering the free tool -- counted up to 670,000 infected OS X machines in the botnet last week; today has seen just 227,493 so far, up from 208,301 yesterday.

Over the weekend, Kaspersky saw a major dip in the number of active infected Macs, from a head count on Friday, April 6, of 650,748, to 248,723 on Saturday, and then 237,103 on Sunday.

Apple has released a fresh Java update, designed to remove the Flashback Trojan malware that exposed Macs to a botnet.

As promised, Apple has released a tool to remove Flashback from infected Macs.

News that nearly two percent of all Mac users have had their computers infected by the Flashback malware which roped them into a 600K strong botnet has hit the Mac community with the realization that ===> their machines are not as secure as they believed and hoped they are. <===

Meanwhile, the Flashback botnet has shrunk in the last few days and as of yesterday, counts less than 270k infected machines.

According to Symantec, part of the reason for this dramatic decrease is the fact that a number of security firms have executed sinkholing operations against the botnet, but the biggest reason likely lies in the fact that many Mac users have heard the news and proceeded to scan and disinfect their machines.

Fünf Jahre alte Samba-Lücke bedroht Mac OS X und Linux

Ein Angreifer kann über die Schwachstelle Schadcode einschleusen und ausführen. Die Open-Source-Software, die anderen Betriebssystemen die Nutzung von freigegebenen Windows-Dateien und -Druckern ermöglicht, ist in vielen Linux-Distributionen und ===> Apples Mac OS X Server <=== enthalten.

Problem: Betroffene Netzwerkdrucker und -speicher lassen sich möglicherweise aktualisieren.

To help consumers understand online risks and practice safe behaviors, Webroot security experts recommend the following:

- Phone home safely - Mobile malware is on the rise, especially on Android devices, so take a moment to swing by the marketplace or app store to install a mobile security application that will safeguard your device against attacks. Many security apps can also help you locate your phone if it is lost or stolen.

- Be wary of WiFi - It can be tempting to take advantage of free WiFi access points in airports, hotels or cafes, but resist the urge to use those connections to do anything other than browse.

Unsecured wireless connections can leave you vulnerable to a variety of risks, from data-stealing malware to wireless snooping of your logins or email messages by other travelers and guests.

Apple is developing a tool to "detect and remove" a Trojan that is believed to have infected around 650,000 Macintosh computers.

It said it is working with internet service providers (ISPs) to disrupt the command network being used by hackers to exploit the malware.

Trojans are infections that can expose computers to control by hackers.

It is Apple's first statement on the threat. It issued patches to prevent the malware's installation last week.

The two security updates were released ===> eight weeks after Java's developer Oracle issued a fix for other computer systems. <===
