Unveiling the GTA 6 Malware: A Sophisticated Threat to macOS Users

In a recent analysis, security researchers at Moonlock discovered a highly sophisticated macOS malware disguised as a yet-to-be-released video game, GTA 6. This malware extracts sensitive information, such as passwords, from a user’s local Keychain, highlighting the increasing sophistication of threats targeting macOS.

Despite the growing popularity of Macs, there is a persistent misconception that they are immune to malware. However, the reality is quite different. Malware targeting macOS is on the rise, with 21 new families discovered in the wild last year alone, marking a 50% increase from 2022.

Unveiling the GTA 6 Malware: A Sophisticated Threat to macOS Users

The newly discovered malware, a variant of password-stealing ware (PSW), masquerades as either GTA 6 or a pirated version of Notion, leveraging social engineering tactics to deceive users into downloading it. Once executed, the malware bypasses macOS Gatekeeper, a security feature designed to prevent the installation of unsigned applications, by exploiting user trust.

Upon execution, the malware initiates a series of actions to achieve its malicious objectives, including phishing for credentials, targeting sensitive data, system profiling, and data exfiltration. One of its notable techniques involves deploying a fake helper app installation window to trick users into revealing their system password, thereby gaining access to the local Keychain database.

The malware is capable of hunting through system directories to collect valuable data, including login credentials from popular web browsers and cryptocurrency wallets. It then stores this data in a secret folder within the user’s home directory, awaiting extraction to an external server controlled by the cybercriminal.

To protect against macOS stealers and other malware, users should:

1. Exercise caution when installing applications from outside the official Mac App Store.
2. Never bypass Gatekeeper or ignore security warnings.
3. Be wary of system prompts or requests for sensitive information.
4. Keep their devices and applications up-to-date to mitigate the risk of vulnerabilities being exploited.

By staying vigilant and following these guidelines, users can help protect themselves against the growing threat of macOS stealers and other malware.
