New Attacks Unleashed by Resurgent Mask APT Group

Title: The Mask Cyberespionage Operation Targets Latin American Organization with Advanced Malware Attacks

Introduction

The Mask, a notorious cyberespionage operation also known as Careto, has recently conducted multiple intrusions against an unnamed organization in Latin America. This alarming development follows a history of nearly 400 compromised entities since 2007. In 2019 and 2022, The Mask utilized sophisticated malware frameworks, including Careto2 and Goreto, to infiltrate systems, as reported by The Hacker News. Understanding the tactics used in these attacks is crucial for organizations looking to bolster their cybersecurity defenses.

The Mask Cyberespionage Operation: A Brief Overview

The Mask has demonstrated a relentless capability for cyberattacks over the years. With its latest operations, the group has showcased advanced techniques that include:

• Careto2 Malware: Targeting Microsoft OneDrive in 2019.
• Goreto Malware: Aimed at Google Drive to facilitate unauthorized access.
• Exploitation of WorldClient: Utilized in 2022 for maintaining persistence within the targeted systems.

Detailed Analysis of Recent Attacks

According to a Kaspersky analysis, the 2022 attack involved exploiting the WorldClient webmail component, which allowed The Mask to establish a foothold within the organization’s network. This operation led to the deployment of the FakeHMP implant, enabling the group to:

• Access sensitive files.
• Log keystrokes.
• Compromise additional malware across the organization’s computers.

Kaspersky researchers also detected another targeted machine using a HitmanPro Alert software driver earlier this year, indicating the group’s evolving strategies.

Key Takeaways on The Mask’s Techniques

Kaspersky’s findings reveal several advanced techniques employed by The Mask, including:

• Persistence Methods: Utilizing the MDaemon email server for maintaining access.
• Complex Malware Deployment: Developing multi-component malware systems that enhance their attack capabilities.

These methods illustrate the sophisticated nature of modern cyber threats and the need for robust cybersecurity measures.
