Homebrew Package Manager Targeted in Malvertising Campaign: What You Need to Know

A recent security breach involving the popular open-source package manager Homebrew has raised alarms among macOS and Linux users. Security researcher Ryan Chenkie uncovered a malicious advertising campaign utilizing fake Google ads to distribute information-stealing malware. This incident highlights the need for heightened vigilance when downloading software from the internet.

Malicious Google Ads Exploit Homebrew Users

Chenkie reported that attackers cleverly used a fraudulent Google ad featuring Homebrew’s legitimate URL, "brew.sh," to redirect users to a deceptive site, "brewe[.]sh." This site tricks unsuspecting users into downloading a compromised version of the Homebrew package manager, which enables the execution of infostealer malware.

  • Primary Threat: Atomic macOS Stealer (AMOS)
    • The malware identified in this campaign, known as the Atomic macOS Stealer (AMOS), poses serious risks. It can compromise various cryptocurrency extensions, desktop wallets, and sensitive web browser information.

Google’s Response and Community Concerns

Homebrew project leader Mike McQuaid expressed frustration over Google’s inadequate vetting processes for advertisements. He pointed out that the malicious ad has since been removed from search results, but the incident raises broader concerns about the platform’s ability to protect users.

  • McQuaid stated, "There’s little we can do about this really; it keeps happening again and again. Google seems to like taking money from scammers."
  • He urged the community to signal-boost this issue in hopes that it prompts Google to implement more stringent security measures.
