Over 600,000 Macs are now affected with the BackDoor.Flashback.39 trojan, according to a report from Dr. Web.
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.
The trojan contacts a control service. Once contact has been made it can download and run the payload on the infected machine. It can run any executable received from a server.
Over 550 000 infected machines running Mac OS X have been a part of the botnet on April 4. These only comprise a segment of the botnet set up by means of the particular BackDoor.Flashback modification. Most infected computers reside in the United States (56.6%, or 303,449 infected hosts), Canada comes second (19.8%, or 106,379 infected computers), the third place is taken by the United Kingdom (12.8% or 68,577 cases of infection) and Australia with 6.1% (32,527 infected hosts) is the fourth.
The 550,000 number has since been updated to 600,000. "At this moment botnet Flashback over 600k, include 274 bots from Cupertino", tweeted Sorokin Ivan of Dr. Web.
Apple yesterday released a security fix for the Java vulnerability. F-Secure has instructions for detection and removal.
Well I replaced OSX with Win7 on my 27" iMac and have never had any virus issues. Its not about OS vulnerability and more down to user vulnerability! (I wonder if anyone has researched any link between getting a virus on your machine and getting an STD!)
my compute is running windows 7 and got infected and I have three antivirus softwares on it it doesn't matter the number that guy is right windows is extremely vulnerable to any attack because most viruses smash through the antivirus soo how do you feel
1) this is a pointless trojan
2) the number claimed is suspiciously high
3) tomorrow evidence shall prove Dr. Webs own calculation were done on a pc and he is who has the virus
Either disable your JAVA or make sure you are updated from the Apple site.
Also consider, removing Adobe Flash player, your Mac does not need it.
And lastly, read careful to what you are asked when installing anything.
Here it comes, let the battle begin! At least in windows people know that they need an anti virur software, with macs noone gave a shit untill now. Come on guys fork out evn more money on new software!
Dude, I can tell from the 'tone' of your writing that you're new in the neighborhood. We, the older Mac users, have been hearing these kind of 'breaking news' concerning Mac viruses for AT LEAST the past 6 years - and guess what? We always consider them as equally important and real as 'world end' announcements made by all those crazy and bogus religious leaders...
Ha you make me laugh Zzz, Anit-virus has been on Macs for decades.
Mac is protected and always updated. Dr. Web has made a mistake and like you failed to understand his findings in hopes to earn some coin.
You're rather ignorant, because if you weren't, you would know there is no such a thing as bullet proof protection, specifically in Windows. No matter if you have 2 Antivirus programs running along with a Firewall and another 2-3 antimalware and antispyware, Windows will eventually 'surrender' to some form of Internet attack or data-exchange contamination. And that's because it is MADE for inviting hell, sooner or later...
...really...wow, my Win7 machine must be crawling with malware....hmmm...nop, ur wrong, better go and buy some antivirus for ur machine...oh wait I forgot u only do what the koolaid tells u....oh well...
Ermm, kiddo, why don't you hurry back to your bedroom before yo momma notices you're being naughty and continue leveling up those WoW characters of yours on your 'beautiful' and 'safe' Win 7 PC, and leave these kind of adult discussions to serious Mac OS X (or even Linux) users...
