Iranian state-sponsored threat actor MuddyWater has conducted a large-scale cyberespionage campaign breaching over 100 government entities and international organizations across the Middle East and North Africa. The attackers leveraged a compromised enterprise mailbox, accessed via NordVPN, to send convincing phishing emails from legitimate addresses to embassies, ministries, and telecom providers. These emails contained weaponized Microsoft Word attachments that, when opened and macros enabled, deployed the updated "Phoenix" backdoor, granting persistent remote access, credential theft, and file exfiltration capabilities. The campaign also utilized off-the-shelf remote management tools such as PDQ and Action1 to blend in with legitimate administrative traffic and pilfered browser passwords from Chrome, Edge, Opera, and Brave.

Researchers at Group-IB highlighted that MuddyWater, also known as Seedworm, APT34, OilRig, and TA450, has demonstrated evolving tradecraft and operational maturity in this operation, mixing official government and personal email addresses to increase the likelihood of successful compromise. The campaign's scale and targeting suggest either a significant increase in capability or a broader intelligence collection mandate from Iranian authorities. MuddyWater, linked to Iran's Ministry of Intelligence and Security, has a history of targeting government, energy, telecom, and defense sectors, focusing on long-term espionage rather than destructive attacks. Analysts warn that further activity is likely amid ongoing regional tensions.

MuddyWater Deploys Phoenix v4 Backdoor via Phishing and VPN Infrastructure

The Iranian state-sponsored threat group MuddyWater has conducted a widespread cyber espionage campaign targeting over 100 government and international organizations, primarily in the Middle East and North Africa. The attackers leveraged compromised email accounts accessed through NordVPN exit nodes to distribute phishing emails containing malicious Word documents. These documents, when opened and macros enabled, deployed the FakeUpdate malware loader, which subsequently decrypted and installed the Phoenix v4 backdoor on victim systems. The campaign focused on diplomatic entities such as embassies, consulates, and ministries of foreign affairs, with the attackers adapting their techniques to bypass modern security controls, including the use of macro-based payloads despite Microsoft's default macro restrictions. Researchers observed that after an initial phase using a command-and-control server, MuddyWater shifted tactics, likely employing additional tools and malware to further their espionage objectives. The Phoenix v4 backdoor, central to this operation, enabled persistent access and data exfiltration from compromised networks. The campaign highlights MuddyWater's continued evolution in attack methods and its focus on high-value government targets through sophisticated phishing and malware deployment strategies.

MuddyWater Cyberespionage Campaign Leveraging Snake Game-Inspired Malware

Iranian state-aligned threat group MuddyWater has launched a new cyberespionage campaign targeting organizations in Israel and Egypt, with a focus on technology, engineering, manufacturing, local government, and educational sectors. Researchers from ESET and other security firms have identified that MuddyWater is using a novel loader, dubbed Fooder, which masquerades as the classic Snake video game to deliver a new backdoor called MuddyViper. This loader introduces execution delays, inspired by the Snake game's mechanics, to evade antivirus detection. The campaign also employs spearphishing emails with PDF attachments that link to remote monitoring and management software installers, hosted on free file-sharing services, to gain initial access. The MuddyViper backdoor enables attackers to collect system information, execute files and shell commands, transfer files, and exfiltrate Windows login credentials and browser data. Additional tools, such as credential stealers and another backdoor named VAX One, have also been deployed. MuddyWater's evolving tactics, including the use of reflective loading for in-memory execution and the impersonation of legitimate software, demonstrate increased sophistication and a continued focus on defense evasion and persistence. Security researchers note the possibility that MuddyWater may be acting as an initial access broker for other Iranian threat actors, given observed overlaps in operations.

MuddyWater (Seedworm) Espionage Campaign Using Dindoor Backdoor Against U.S. Organizations

Security researchers reported a cyber-espionage campaign attributed to Iran-linked **MuddyWater** (aka **Seedworm**), assessed as operating under Iran’s **Ministry of Intelligence and Security (MOIS)**, targeting multiple U.S.-based organizations and related operations. Victims cited across reporting include a **U.S. airport**, a **U.S. bank**, **non-governmental/non-profit organizations** in North America, and the **Israeli operations of a U.S. software supplier** connected to the defense and aerospace sector—indicating interest in both critical infrastructure-adjacent environments and the defense supply chain. The intrusions were described as beginning in **early 2026** (with Symantec/Carbon Black tracking activity starting in early February) and focused on establishing and maintaining access consistent with long-term intelligence collection. One report highlighted deployment of a newly observed backdoor, **Dindoor**, alongside additional tooling to sustain persistence in victim networks, while broader analysis framed the activity as potentially aligned with heightened regional tensions and warned that Iranian-aligned actors may continue reconnaissance and access operations; organizations were advised to increase monitoring and defensive readiness, particularly where exposed services could enable initial access.
