So how does using MacPorts instead of Homebrew protect you from this? The point is that if someone gains access to your local user account, it’s game over for your user, homebrew installed or not. Usually steps 1 & 2 are not even required, as it’s quite common to have a ~/bin directory in user’s PATH, and it’s also not unusual for it to be the first item so you can override system commands if needed.

Adds a password hijacking sudo binary to ~/malicious-bin Modifies your ~/.bashrc (or ~/.zshrc) to add ~/malicious-bin as the first item in your PATHģ. Creates a local directory ~/malicious-binĢ. So the attacker has access to your local account, and then he:ġ. You can join the vulnerability watch if you love learning about cybersecurity too… or just enjoy being scared ).
We have a vulnerability watch where we publish the latest vulnerabilities in many popular programs. If you’re the type that loves hearing about vulnerabilities and loves talking tech, as probably many Homebrew users do, you may be interested in joining the Info Toast Discord.

Sudo port upgrade outdated <- Upgrades all outdated packages Conclusion sudo port selfupdate <- Upgrades a specific outdated package You may want to know a few commands you can run to use it. Navigate to the MacPorts website and download the installer. However, make sure the Xcode command-line developer tools are installed first: xcode-select -install MacPorts installs more like a traditional Mac app than Homebrew. zprofile and remove the line that calls the “brew” command. To prevent you from getting spam when starting your Terminal, use nano or vim to open up. If you’re on Apple Silicon, you will still need to remove the /opt/homebrew directory from your system. Once that is done, there are a few other things you may want to do. Type in the following command to execute the Homebrew uninstallation script: /bin/bash -c "$(curl -fsSL )" Luckily, Homebrew has made it relatively easy to uninstall. How do I uninstall Homebrew for better security? MacPorts also has better support for Apple Silicon.
#Vim brew macports install#
MacPorts will build packages that you install from source, so everything is tailored to your system configuration. As Mac is based on BSD, not Linux, Homebrew is a Linux solution to a BSD problem, while MacPorts is a BSD solution to a BSD problem. There is an alternative to Homebrew that, in my opinion, is way better for security.

In Macs that have Homebrew installed, as the sudo binary is located in /usr/bin, a malicious program can place a script called “sudo” in /usr/local/bin or /opt/local/bin that takes your password and then uses it to allow a virus to gain administrator access. Imagine if someone wanted to make a fake sudo command that grabs your password to elevate itself to administrator. Ok, here’s where the vulnerability comes in. usr/local/bin <- Homebrew makes this writable by you on Intel Macs opt/local/bin <- Homebrew makes this writable by you on Apple Silicon This is how the directories are listed on a Mac without homebrew or anything that alters the PATH variable. The problem is, Apple put /usr/local/bin first in the PATH environment variable. It will find the first one that is first in the list of directories. When the user types in a command, the system looks through each directory until it finds one. The best way I can describe this is that the PATH environment variable includes a list of directories that contain binaries. This doesn’t seem that bad on the surface until you factor the PATH environment variable in. Homebrew made the installation directory for packages, /usr/local/bin (Yes, I know it’s /opt/local/bin on Apple Silicon), writable to the user that installed Homebrew. However, as any experienced UNIX people know, poking holes in the system never ends well. A while back, Homebrew ditched the use of sudo in a move that many praised. I was trying to find knowledge about how the Homebrew team greenlights their packages to ensure that it’s not filled with viruses. However, I’ve never seen a binary package manager that creates more of a security problem having it than not having it.

I have praised BSD’s Ports, where a source code tree allows you to install packages from source with all their dependencies. I’ve talked before about the various problems with binary package management systems.
