The OSX/Revir.A trojan downloader works by downloading and constantly launching a PDF file containing offensive political statements in Chinese, and then installing a backdoor (known as “OSX/Imuler.A”) onto the victim’s Mac to potentially allow malicious access to it. The backdoor then sets up a launch agent on the victim’s Mac which keeps the malware active and sends the infected Mac’s username and MAC address to a remote server.

Antivirus makers are locked in an eternal two-step with virus coders, blocking today’s virus only to wake up tomorrow to find a new variant out in the wild. Should Apple follow suit, and begin the sisyphean task of trying to stay ahead of malicious coders, knowing the end result is, in essence, eternal gridlock? Or, could there be another way to keep the Macintosh the virus-free paradise longtime users have come to know and love?

In a new support document from Apple, the company acknowledges the existence of malware known as MACDefender (along with other variants) that acts as anti-virus software in an attempt to steal a user’s credit card information by persuading them to register the software. Apple has also stated that an update for Mac OS X is on its way to get rid of the malware and warn users should they be brought to a web page where the malware is present.

Yes, we’re all aware that the Mac is pretty solid against viruses, but it’s not impervious. Evidence of this comes from a report at 9to5Mac in which they state, “Security researchers at Symantec have uncovered what they suspect may be the first Mac OS X botnet launching denial-of service attacks.” Of course, to get it, you have to bypass Apple’s warnings and break the #1 rule of downloading content from the web, but you know, malware nonetheless.

The International Space Station has been infiltrated. That’s right, a virus has made it’s way onto the computers of the International Space Station. The computers, running Windows XP, were non-mission-critical, containing things like e-mail and “nutritional experiments.”

The computers were infected by the W32.Gammima.AG worm, which harvests credentials for online games. Somewhat disconcertingly, the virus has spread since its entry into space, meaning that it is on some sort of onboard drive or intranet.

More after the break.

Mac users have been free of virus’ for about 31 years now, but 93% expect that Macs will have more malware and virus attacks. Sophos, a computer security company, conducted a survey with about 350 computer users and they believed that Apple’s Macintosh computers will be targeted more frequently in the future.
