Mac users beware. A variant on an established Trojan for the Apple Mac OSX operating system has been discovered by Sophos.

OSX/MusMinim-A is a Remote Access Trojan (RAT) for the OSX platform, which is also known as “BlackHole RAT”. SophosLabs analyzed the sample it received and determined that it is a variant of a well-known Remote Access Trojan (RAT) for Windows known as darkComet.

So far, the trojan’s unknown author describes it as a “beta” version, whose functionality could be improved over time. OSX/MusMinim-A’s main threat component is a backdoor, which acts as the server half of a client-server pair of applications, the company said.

Sophos, which discovered the BlackHole RAT Trojan, claims that it can remove it (whew!) with its Sophos Anti-Virus product for the Macintosh, which it distributes for free (Yey! Free!). The most common way that your mac may be infected, according to Sophos, is by downloading the trojan as part of pirated software.

According to a Sophos blog post authored by Chester Wisniewski, the Trojan’s basic functionality includes:

  • Placing text files on the desktop
  • Sending a restart, shutdown or sleep command
  • Running arbitrary shell commands
  • Placing a full screen window with a message that only allows you to click reboot
  • Sending URLs to the client to open a website
  • Popping up a fake “Administrator Password” window to phish the target

In its present form, a message will also pop up next to the reboot command: “I am a Trojan Horse, so i have infected your Mac Computer,” it says. “I know, most people think Macs can’t be infected, but look, you ARE Infected! I have full controll over your Computer and i can do everything I want, and you can do nothing to prevent it. So, Im a very new Virus, under Development, so there will be much more functions when im finished.”

Cult of Mac weighs in with claims from a new source regarding the new MacBook Air that has been receiving considerable attention in the days leading up to Apple’s media event on Wednesday. The new report corroborates many of the claims coming from other sources, but also offers a few new details on what we might expect in the new machine.

  • Battery life rumored to be 8-10 hours, up from 5 in the current MacBook Air.
  • Thinner and lighter form factor with fewer curves.
  • Two USB ports, SD card slot, straight-style MagSafe, Mini DisplayPort.
  • Base model with 2 GB of RAM, but upgradeable. SSD also upgradeable.
  • NVIDIA GeForce 320M graphics.
  • Unconfirmed CPU claims of 2.1 GHz and 2.4 GHz options, but no claim of a specific processor family is offered.
  • Suggestion of $999 for 11.6-inch model and $1100 for the 13.3-inch model, but Cult of Mac believes something like $1100/$1400 to be more likely.

Now what does a new model mean? Older models get cheaper! But the problem again is that the new models tends to really overshadow the old ones so people will still prefer the latest. Apple really knows how to screw around with people he he he.

After more than 4 years, it is now time to bid farewell to my Macbook battery. I think it is a durable one since everything would have still been alright if I did not upgrade the operating system to Snow Leopard. When I did, the battery went from durable to useless. Suddenly my Macbook runs out of power even if the status says something like 80%.

Apple did say that Snow Leopard’s new feature is that it detects the real lifespan of the laptop’s battery. But I wondered why when it was still at Leopard, everything was still okay. The moment I upgrade to Snow Leopard was the time that the battery problem showed up.

I did not want to revert back to the old operating system anyway because I wanted to use the latest version of the operating system anyway. Besides, that time my battery was more than 3 years old so I guess it met its lifespan. And this morning when I plugged my charger to my Macbook, it never turned itself on until after around 40 minutes.

Crap! I decided then to buy a new battery. It’s long overdue anyway.
