Students then changed the rates that zombies were treated/quarantined in each of these models in order to view the impact these rates would have during a zombie apocalypse. According to the students, our best chance of survival is treating the zombie virus, however even that does not give us much of a chance against a zombie population. Zombie mode was added to the game last year, only to be removed after a couple of months. Also Read: Gunsmith in COD Mobile: All we know so far. Zombie Mode was a game mode that was widely. Malware + Recommended + Security News. IWorm Botnet Uses Reddit as Command and Control Center. Posted on October 2nd, 2014 by Derek Erwin A new day, and a new threat to Mac OS X. Virus hunters have discovered a sophisticated botnet targeting Mac OS.
Sometimes when dealing with the so-called Mac faithful -- diehard users who relentlessly demean and attack anyone (reporters, particularly) who doesn't share their unquestioning enthusiasm -- I think of the 'Walking Dead'; TV show or comic, it's your choice. Nothing stops their relentless, mindless walk. As if there weren't zombies enough, cybercriminals have unleashed another kind that is much worse.
Late last week, I started following progress of a new Trojan injected via rogue Java applet. Flashback is a variant of older malware and Apple issued a patch, so I chose not to write about it. Whoa, that was a mistake. Yesterday, Russian security firm Dr. Web claimed that more than 600,000 Macs are infected and part of a sophisticated botnet. Cybercriminals have amassed a sizable army of zombie Macs. Let me take a moment to welcome Mac users to zombieland -- a place many Windows users have lived for years.
No One is Safe

Trojans are nothing new, they're just not as common on Mac OS as Windows, but they're increasingly common enough for concern. For all the other Mac zombies -- let's call them the Walking Dead for differentiation -- who claim there is no Mac malware, 600,000-plus is nothing, nothing. Close your eyes and wish them away.
Two May 2011 BetaNews polls found that eight out of 10 Mac users don't have anti-malware installed, while as many Windows users do. I've started the polls anew, to see what's changed, if anything, in 11 months. Please respond to them. The Walking Dead aren't only to blame here as I explained last year: 'Apple has created, by asserting things like 'Mac OS X doesn't get PC viruses,' a false sense of Mac security'.
'Despite what Apple's marketing department would have you believe, Macs are not invulnerable to attacks and malware targeting OS X does exist', security consultant Adrian Sanabria explains. 'Our main takeaway from [Flashback] should be that many Mac users have been lured into a false sense of security, and will be, or may already be, in for a rude awakening'.
Think about something. From where is the Mac install base growing? Windows users. Apple executives consistently say that half of Mac buyers are Windows users. As Mac Defender showed last year, successful Mac malware uses the same social engineering techniques common to Windows PCs. Windows users bring bad habits to the Mac, which Mac Defender showed can be exploited as easily on Apple computers as Windows PCs.
Then there is the Walking Dead and other long-time Mac users who aren't accustomed to their computers being assaulted. They're naive and leave the windows open and doors unlocked, so to speak. They feel safe when they shouldn't and don't know what behavior creates risk. Yes, I'm generalizing, but the point is valid.
Risks increase with malware success. Botnets this size are self-propogating. Cyberciminals can use a large botnet to attack and infect other computers. Can this one be taken down? We shall see.

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.

More specifically, how are Macs infected? Security vendor F-Secure explains:
Trojan-Downloader:OSX/Flashback.I is dropped by malicious Java applets that exploit the known CVE-2011-3544 vulnerability.
On execution, the malware will prompt the unsuspecting user for the administrator password. Whether or not the user inputs the administrator password, the malware will attempt to infect the system, though entering the password will affect how the infection is done.
If infection is successful, the malware will modify the contents of certain webpages displayed by web browsers; the specific webpages targeted and changes made are determined based on configuration information retrieved by the malware from a remote server. Amphibian mac os.
F-Secure also offers detailed instructions to detect and remove Flashback.
Apple has patched the vulnerability but took six weeks doing so. Meanwhile, like Mac Defender, new Flashback variants spread. Will you be a Mac zombie, or are you one already? Now might be a good time to invest in a Mac anti-malware app.
The Russian antivirus vendor Dr. Web has reported the spread of a new botnet that exclusively targets Apple computers running Mac OS X. According to a survey of traffic conducted by researchers at Dr. Web, over 17,000 Macs worldwide are part of the Mac.BackDoor.iWorm botnet—and almost a quarter of them are in the US. One of the most curious aspects of the botnet is that it uses a search of Reddit posts to a Minecraft server list subreddit to retrieve IP addresses for its command and control (CnC) network. That subreddit now appears to have been expunged of CnC data, and the account that posted the data appears to be shut down.
The Dr. Web report doesn't say how Mac.BackDoor.iWorm is being distributed to victims of the malware. But its 'dropper' program installs the malware into the Library directory within the affected user's account home folder, disguised as an Application Support directory for 'JavaW.' The dropper then generates an OS X .plist file to automatically launch the bot whenever the system is started.
AdvertisementThe bot malware itself looks for somewhere in the user's Library folder to store a configuration file, then connects to Reddit's search page. It uses an MD5 hash algorithm to encode the current date, and uses the first 8 bytes of that value to search Reddit's 'minecraftserverlist' subreddit'—where most of the legitimate posts are over a year old.
The CnC posts appear to now have been expunged from Reddit, and a survey of the most recent servers identified in the subreddit by Ars found that most of their IP addresses, scattered around the world on systems that were apparently compromised—including computers in Slovakia and at Marist College in Poughkeepsie, New York—are now unreachable. The Marist College node, based on its IP address, was a virtual machine running in the college's private cloud.

However, it's unlikely that the botnet has been completely shut down. The malware has the capability of downloading additional files and executing commands on the infected systems, so a new version of the botnet may have already been distributed—along with other malware spread through it.
Security journalist Graham Cluley reports that Dr. Web and Bitdefender both detect variants of the botnet, (which Bitdefender refers to as Mac.OSX.iWorm). There are also ways for Mac owners to defend themselves against the malware. Developer Jacob Salmela has posted instructions on how to create a set of OS X folder actions that will alert a user if their system becomes infected.
