New Malware Used in Cloud Atlas Cyber Attacks

Title: New VBCloud Malware Targets Russian Users in Data Theft Campaign

Introduction
A new wave of cyberattacks has emerged, featuring the VBCloud malware, which is being deployed by the Russian state-backed group known as Cloud Atlas. This sophisticated threat operation, also referred to as Clean Ursa or Red October, has been linked to multiple data theft incidents, primarily affecting users in Russia. According to a recent report by The Hacker News, the VBCloud malware campaign utilizes phishing tactics to compromise users and extract sensitive information.

Understanding the VBCloud Malware
The VBCloud malware is part of a broader strategy employed by Cloud Atlas to execute data theft effectively. Here’s how the attack typically unfolds:

• Phishing Emails: Attackers send emails containing malicious Microsoft Office documents.
• Exploitation of Vulnerabilities: These documents leverage an Equation Editor vulnerability, identified as CVE-2018-0802, to download an RTF template.
• Execution of Malicious Payloads: The exploit executes an HTML Application file that establishes both launcher and cleaner files for the VBShower backdoor.

Key Features of VBCloud Malware
The VBCloud malware is designed for efficiency in data gathering and infiltration. Here are some of its critical functionalities:

• Information Gathering: It collects disk information, system metadata, and various document formats, along with files related to Telegram.
• PowerShell Payloads: The malware enables the deployment of multiple PowerShell payloads through a component known as PowerShower.
• Network Probing: PowerShower can probe local networks, facilitating further infiltration into connected systems.

According to Kaspersky researcher Oleg Kupreev, the infection chain of VBCloud is multi-staged, ultimately aiming to extract valuable data from victims’ devices.
