What is BYOB?

First, let’s get into what even is BYOB. The acronym stands for Build Your Own Blocks, and it’s an educational game aimed at helping kids get into the world of coding and programming.

The biggest issue with BYOB is that it’s open-source. That opens the door to quite a few different scenarios.

The first issue is that anyone can modify the source code and then re-upload it to trick people into downloading a corrupted or malicious version. The second problem is that it leaves itself wide-open for hackers to play with it and figure out how to exploit, which they’ve done repeatedly and with some success.

How can a Mac get infected with BYOB botnet?

BYOB is almost always manually installed by the user. When the user downloads the BYOB installer from a malicious source, a Mac may get exploited by the botnet.

So although you may download BYOB voluntarily, you may not know this exact framework is malicious. Once BYOB is installed on your Mac, hackers can remotely control your machine along with other devices by setting up a BYOB botnet. It won’t necessarily be obvious and may be more hidden so that the hackers can use the machine's processing power.

How can it harm my Mac?

When the BYOB botnet is installed on a Mac, a hacker may try to use your computer’s power to run certain tasks. Usually, those are nefarious tasks and sometimes less than legal. But, at any rate, if a machine is being used for its background processing power, it will run slower, using up every last CPU resource, potentially overworking and damaging your internal components.

Manual steps to remove BYOB botnet from Mac

Now, if you prefer to do things your way, then you can definitely remove the BYOB botnet from Mac manually. It’s not difficult per se, but it is a bit time-consuming. There are multiple steps to the process: the first one is to delete the BYOB app itself.

  1. Open a new Finder window.
  2. Click Go > Applications.
  3. Then, find BYOB.
  4. Now, drag the icon to the Trash in your dock.

Unfortunately, BYOB also installs quite a few support files along with it. So, you’ll need to hunt for those and delete them too. But, you can do that by following these steps:

  1. In Finder, click Go > Go to Folder…
  2. Type in: ~/Library
  3. Open the Application Support folder.

  4. Then, delete any files you see related to BYOB.
  5. Click the back arrow.
  6. Repeat steps 3-5, but go into the folders for: Caches, Preferences, and Saved Application State.

Once you’re done deleting the files, go ahead and empty your Trash. Then, reboot your Mac for good measure. Rebooting will shut down currently running software and remove unneeded cache – this includes all of the support files that might have been used in the background.
