Vortax Meeting Software: Hackers' New Weapon Against macOS Users!

A cyberattack campaign by threat actor “Markopolo” leverages fake virtual meeting software called Vortax to distribute information stealers (Rhadamanthys, Stealc, and AMOS) targeting cryptocurrency users on macOS

The malware, disguised as a legitimate application with a website, social media presence, and fake reviews, exploits macOS vulnerabilities to steal user credentials upon download and installation, highlighting a potential rise in AMOS attacks and the growing sophistication of macOS malware targeting cryptocurrency users. 

An attacker campaign is leveraging Vortax, a fake virtual meeting software, to target macOS users, and upon installation, Vortax infects the system with three information stealers: Rhadamanthys, Stealc, and Atomic macOS Stealer (AMOS). 

It seems to focus on stealing cryptocurrency and highlights a concerning rise in macOS threats, while the attackers also maintain a broad network of malicious applications, suggesting potential for further attacks. 

It targets vulnerabilities in macOS to steal user credentials, likely focusing on cryptocurrency wallets and accounts, based on the connection to a prior Web3 gaming attack by the same actor, which highlights a potential rise in malware targeting macOS users and the need for robust security measures. 

A threat actor leverages shared hosting and command and control (C2) infrastructure for agility, which enables them to swiftly switch to new scams upon detection. 

The campaign suggests a large-scale credential harvesting operation, potentially positioning Markopolo as an initial access broker or “log vendor” on illicit marketplaces like Russian Market and 2easy Shop. 

Providing other cybercriminals with access to compromised systems could be accomplished by Markopolo through the sale of stolen credentials.  

To combat AMOS infections, a multi-pronged approach is recommended, as intrusion detection and prevention systems must undergo regular updates to effectively identify and block threats

User awareness campaigns should highlight the dangers of downloading unapproved software, particularly from untrusted sources like social media and search engines. Additionally, robust security controls should be implemented to restrict unlicensed software downloads. 

According to Recorded Future’s Insikt Group, enhancing a culture of vigilance by encouraging users to report suspicious online activity can further strengthen the organization’s cybersecurity posture. 

A new macOS malware campaign using pirated software distribution highlights the evolution of cyber threats, and the ease of infecting macOS systems through popular channels demonstrates a growing demand for this type of malware. 

This demands a recalibration of the security posture for macOS environments, including robust multi-stage defenses. Proactive threat monitoring and mitigation strategies are now essential to safeguarding digital environments from these sophisticated attacks.
