- Actor Motivations: Espionage,Exfiltration
- Attack Vectors: Malicious Macro,Malware,Spear Phishing
- Attack Complexity: Medium
- Threat Risk: High Impact/High Probability
Threat Overview
The MuddyWater APT group carried out a series of spear-phishing attacks between February and April 2019. They targeted government entities, educational institutions, financial, telecommunication, and defense companies in Turkey, Iran, Afghanistan, Iraq, Tajikistan, and Azerbaijan. The group used a tool named muddyc3, capable of delivering a PowerShell payload and managing C&C server communication. Researchers discovered that the tool supports a variety of commands, indicating the use of a command-line interface. It also utilizes character substitution and base64 encoding for obfuscation.

FAQs
MuddyWater APT "muddyc3" Tool Leak
Hackers leaked and auctioned the source code for a hacking tool called "muddyc3" on the messaging app Telegram. Following this leak, cybersecurity researchers obtained the files, analyzed how the tool works, and published their findings to the public to help organizations defend against it.
The tool belongs to MuddyWater, a well-known, long-standing cyberespionage group operating primarily in the Middle East. However, the exposure of the tool itself was done by independent actors on Telegram, including a group known as "GreenLeakers," who were attempting to sell the group's data.
The leaked software is a control framework used after hackers have already broken into a computer network. Its primary goal is to allow the attackers to securely communicate with the compromised computers, deliver additional malicious software, and collect or steal sensitive information.
Yes, MuddyWater typically targets high-value organizations. Based on their historical activity, they focus on government entities, educational institutions, financial organizations, telecommunications providers, and defense companies.
While the current leak exposes the tool itself, previous campaigns using MuddyWater's tactics have been regional but highly impactful. They have previously targeted organizations across Turkey, Iran, Afghanistan, Iraq, Tajikistan, and Azerbaijan.
The attackers generally start by sending out highly targeted "spear-phishing" emails containing malicious documents. When a victim opens the document and enables hidden code (called macros), it silently connects back to the attacker's server to download the muddyc3 tool, giving the hackers ongoing control of the machine.
The targeted sectors—such as defense, government, and telecommunications—hold highly sensitive national security data, financial records, and intellectual property. Compromising these networks allows the attackers to conduct long-term espionage and intelligence gathering.
Organizations should disable automatic macro execution in documents and continuously train employees to recognize phishing emails. IT departments should also use the newly available information about this leaked tool to update their security systems and monitor for any unusual network connections.
This is a targeted threat. While the tools themselves are now public, the MuddyWater group historically focuses their efforts on specific regions and specific high-value industries rather than conducting widespread, random attacks against everyday consumers.
