How a Password Manager Shields macOS Users from Cyber Attacks

Password-theft malware poses a new threat, and Mac computer users must be extra watchful. This new generation of malware builds on users’ innocence through malicious advertisements and fake app installers. Cybersecurity analysts have identified three major threats: Atomic Stealer, Poseidon Stealer, and, the latter of whom has been ironically named, Cthulhu Stealer. Each has a distinctive MO and distribution method.

Security experts at Palo Alto Networks’ Unit42 were intently monitoring these threats and warning that they are becoming increasingly sophisticated. 

Let’s examine how these stealers perform better and how users can guard themselves.

The Three Notorious Malware Threats

So, what are the effective and famous malware threats? Let’s navigate through that:

Atomic Stealer: A Persistent Threat

First found in April 2023, Atomic Stealer (AMOS) is a malware-as-a-service (MaaS) offered on hacker forums and Telegram. Originally written in Go, it has since been updated to C and occasionally includes Python scripts or Mach-O binaries. 

Atomic Stealer mainly spreads via malvertising and focuses on exfiltrating sensitive data including:

• Browser passwords
• Cryptocurrency wallets
• Instant messaging data

How It Works

Once launched, the malware disguises itself as a legitimate installation file trying to access the stored login credentials of Google Chrome from the “Login Data” folder.

Poseidon Stealer: The Deceptive Intruder

Poseidon Stealer is believed to have been developed by “Rodrigo4,” an alleged former Atomic Stealer developer. It typically arrives as a Trojanized installer – in many cases advertised on Google or through phishing emails, impersonating legitimate apps.

How It Works

During the installation, Poseidon Stealer employs an obfuscated AppleScript and asks for user passwords in order to gain access to macOS. Once access is gained, Poseidon pilfers browser passwords, crypto wallets, Telegram data and Notes files, which are sent back to the attacker-controlled server.

Cthulhu Stealer: The File Hunter

Cthulhu Stealer once again joins the fray, being actively sold through Telegram under the auspices of a group that calls itself the “Cthulhu Team.” It is written in Go and distributed by exploiting unprotected users by installing malicious applications.

How It Works

The malware uses fake pop-up dialogs to convince the victims to insert their passwords, including MetaMask credentials. First, it saves the stolen data to the /Users/Shared/NW directory before sending it to a command-and-control server.

How to Stay Protected

To counter these increasing threats, experts advise using advanced detection tools like Cortex XDR to monitor unusual AppleScript executions and detect attempts at accessing sensitive files.

Meanwhile, you can follow these measures to stay secure: 

• Keep watch for phishing popups or uncertain password requests
• Run regular security updates
• Take a layered approach
• Use a password manager to compartmentalize passwords
• Only download files from trusted sources.

With the rise of password-stealing malware, Mac users should remain wary and take the initiative to secure sensitive information.
