Iranian Cyber Espionage Group MuddyWater Exploits New C2 Framework in Telecom Sector Attacks

The Iranian nation-state actor known as MuddyWater has recently intensified its cyber espionage activities, targeting the telecommunications sector in Egypt, Sudan, and Tanzania. This group, assessed to be affiliated with Iran’s Ministry of Intelligence and Security (MOIS), has been diligently expanding its toolset and employing innovative techniques to evade detection and fulfill its strategic objectives. In these operations, MuddyWater has capitalized on a newly discovered command-and-control (C2) framework called MuddyC2Go, reinforcing its reputation as a persistent and sophisticated threat actor.

Tracking the activity of MuddyWater

The Symantec Threat Hunter Team, now part of Broadcom, has been diligently monitoring the activities of this cyber espionage group under the umbrella name Seedworm. However, MuddyWater is also tracked under various other aliases, including Boggy Serpens, Cobalt Ulster, Earth Vetala, ITG17, Mango Sandstorm (formerly Mercury), Static Kitten, TEMP.Zagros, and Yellow Nix. This diverse range of pseudonyms underscores the varying tactics and techniques employed by MuddyWater to launch its attacks.

Affiliation with Iran’s Ministry of Intelligence and Security (MOIS)

MuddyWater’s primary focus has been to target entities in the Middle East, carrying out cyber espionage campaigns aligned with Iran’s strategic interests. With a suspected affiliation with Iran’s Ministry of Intelligence and Security (MOIS), MuddyWater operates with clear objectives and direction.

Introduction to the MuddyC2Go Framework

MuddyWater’s recent activities highlighted the use of a newly discovered command-and-control (C2) framework called MuddyC2Go. Deep Instinct, a cybersecurity firm, initially identified this Golang-based C2 framework as a successor to MuddyC3, which had replaced PhonyC2. The adoption of MuddyC2Go by MuddyWater demonstrates the group’s constant efforts to develop and enhance its offensive capabilities.

Tools utilized in recent attacks

The cyber espionage group’s attacks in November 2023 revealed a combination of tools leveraged for intrusion. MuddyWater utilized SimpleHelp and Venom Proxy alongside a custom keylogger and other publicly available tools. By utilizing this diverse arsenal, the group aimed to maximize its chances of success and remain undetected for extended periods.

Attack strategy and methodology

Consistently, MuddyWater’s attack chains have relied on sophisticated tactics, including weaponizing phishing emails and exploiting known vulnerabilities in unpatched applications, thereby gaining initial access. Following successful infiltration, the group performs reconnaissance, lateral movement within the target network, and extensive data collection. This multi-phase approach allows MuddyWater to execute its cyber espionage operations efficiently.

Use of MuddyC2Go in Attacks on Telecommunications Organizations

Symantec’s research has uncovered attacks on an unnamed telecommunications organization where MuddyWater employed the MuddyC2Go launcher. This launcher helped establish contact with a server under the actor’s control. Additionally, MuddyWater deployed legitimate remote access software, such as AnyDesk and SimpleHelp, to further their foothold within the targeted organization.

Evading Detection and Strategic Objectives

By combining bespoke, living-off-the-land, and publicly available tools, MuddyWater aims to remain undetected for prolonged periods, enabling the achievement of its strategic goals. Evading detection allows the group to persistently gather sensitive information and execute its cyber espionage campaigns effectively.

Continuous Innovation and Toolset Development

MuddyWater’s commitment to innovation and toolset development is evident in its continuous adaptation to stay under the radar. The group consistently refines its techniques, modifies tools, and develops new tactics as required to maintain stealth and effectiveness in its cyber operations.

The significance of PowerShell in attacks

PowerShell and PowerShell-related tools and scripts remain central to MuddyWater’s attack methodology. The group heavily relies on this scripting language, emphasizing the critical need for organizations to remain vigilant and monitor any suspicious use of PowerShell within their networks.

MuddyWater, an Iranian nation-state actor affiliated with Iran’s Ministry of Intelligence and Security (MOIS), continues to pose a substantial threat to organizations, particularly in the telecommunications sector across Africa and the Middle East. The group’s utilization of the newly discovered MuddyC2Go framework, alongside its dynamic and evolving toolset, demonstrates its determination and sophistication. Security professionals and organizations must remain vigilant, continuously update their security measures, and closely monitor suspicious activities to effectively mitigate the risk posed by MuddyWater and similar threat actors.
