MuddyWater Exposed: An Iranian APT's Entire Offensive Toolkit Recovered from an Open Directory

Published: 2026-03-08 | Author: FGBOT | Classification: TLP:CLEAR

TL;DR

An Iranian APT operator accidentally exposed their entire /root home directory via Python SimpleHTTPServer, revealing four custom C2 frameworks with full source code, six weaponized CVE exploits (including 2026-era zero-days), 785 GB of exfiltrated nation-state data from five sovereign targets, and a cross-ecosystem connection to the Russian-operated Tsundere Botnet. This is one of the most comprehensive OPSEC failures by a state-sponsored threat actor documented in open-source intelligence.

---

The Discovery

It started with a single tweet: an open directory at 157.20.182[.]49:8000 linked to MuddyWater. What followed was a multi-week OSINT investigation that went far beyond the original finding. The operator had exposed their entire /root home directory on port 8888 via Python SimpleHTTPServer -- not just a staging directory, not just a payload drop, but their complete operational workspace. Bash history. SSH keys. Cloud credentials. Source code for every tool they use. Victim data. Target lists. The full operational timeline of an active Iranian APT campaign.

108 files were downloaded and analyzed. Four C2 frameworks were reverse-engineered. Six CVE exploits were documented. 37+ compromised email accounts were cataloged. Named Israeli VPN users were identified from a FortiGate exploitation campaign. A connection to a Russian cybercrime botnet was uncovered. And 785 GB of actively exfiltrating nation-state data was found across multiple cloud storage accounts.

Server Infrastructure

157.20.182[.]49 -- MuddyWater Primary C2/Staging Server

Property	Value
Hosting	Hosterdaddy Private Limited, AS152485
PTR	mail1.bestnewslettersclub.com
OS	Ubuntu Linux, Python 3.12.3
Open Ports	22 (SSH), 443 (resocks mTLS), 5000 (Flask C2), 8000 (FastAPI C2), 8888 (open directory), 9090 (file serving), 31337 (Sliver C2)

The server runs five distinct C2 frameworks simultaneously: a custom UDP C2 ("UDPGangster") on a co-located IP, a Flask/SocketIO HTTP C2 on port 5000, a FastAPI C2 on port 8000, a TCP C2 on port 5009, and BishopFox's Sliver framework on port 31337. Port 443 hosts a mutual-TLS resocks SOCKS5 proxy. Port 8888 is the exposed open directory. This is not a single-purpose server -- it is the team's central operational hub.

Four Custom C2 Frameworks: Full Source Code Recovered

Framework 1: UDPGangster -- UDP Port 1269

Source file: udp_3.0.py (1,310 lines of Python)

This is the custom UDP C2 previously identified by FortiGuard Labs. PDB paths in associated binaries reveal developer handles "gangster" and "SURGE." The protocol implements 13 packet types over UDP with a SQLite backend for victim tracking:

Packet Type	Code	Function
FIRST	0	Initial beacon/registration
ACK	2	Acknowledgment
PING	4	Heartbeat keepalive
RESET	6	Connection reset
CMD	10	Command request
CMD_END	11	Command completion marker
CMD_EXEC	12	Command execution
DOWN	20	File download (exfiltration)
DOWN_END	21	Download complete
UPLO	30	File upload (staging)
UPLO_END	31	Upload complete
FUNC_TIME_OUT	66	Operation timeout
IP_CHANGE	99	Client IP change notification

The operator commands follow a simple prefix syntax: +cmd for command execution, +download for exfiltration, +upload for staging payloads, +stage for deploying implants, and +sleep for adjusting beacon intervals. The client tracking SQLite database records computer name, domain, Windows version, and username for each implant callback.

Known C2 endpoints: 157.20.182.75:1269/UDP, 64.7.198.12:1269/UDP Delivery domain: reminders[.]trahum[.]org Persistence path: %AppData%\RoamingLow\SystemProc.exe

Framework 2: Flask/SocketIO HTTP C2 -- Port 5000

Source file: im/c2/server.py

A full web dashboard C2 with real-time WebSocket updates via Flask-SocketIO. The source code reveals default credentials (admin_me / admin123_me), a math-based captcha for login, and XOR encryption with a hardcoded key:

# encryptions.py -- recovered from the open directory
def enc_string(input_string: str) -> str:
    key = "mysecretkey"
    # تبدیل string به bytes  <-- Farsi comment: "convert string to bytes"
    data_bytes = input_string.encode()
    xored = xor_decrypt(data_bytes, key)
    encoded = base64.b64encode(xored)
    return encoded.decode()

The Farsi code comment is one of several Persian-language artifacts confirming Iranian attribution. The encryption is trivially reversible -- XOR with a static key followed by Base64 -- but the framework is functional and actively used.

The C2 database contained a single registered client:

Field	Value
Username	llvm
Computer	DESKTOP-2TE9E08
OS	Windows 11
IP	185.138.89.4
Country	Portugal
Last Seen	2026-02-24

Investigation of this "victim" revealed it is actually the operator's own development machine, not an external target. The desktop listing (captured via C2 command) contained:

• bahman.txt and esfand.txt -- Persian calendar months (Bahman = Jan-Feb, Esfand = Feb-Mar)
• Exploit directories: forti/, egypt/, owa/, BeyondTrust/, CVE-2024-23113-main/
• Development tools: Visual Studio Code, Windsurf AI IDE, .pdb debug symbols
• Offensive tooling: cracker.py, shodanexp.py, pass.txt, wallet/

The IP 185.138.89.4 resolves to a compromised MikroTik RouterOS 7.7 device with hostname mik-pt.f2p.shop, used as a VPN hop-point through Russian bulletproof hosting (Global Connectivity Solutions LLP / Stark Industries) to geolocate as Portuguese.

Framework 3: TCP C2 -- Port 5009

Source file: tcp_serv.py

A simpler binary-packet TCP shell with structured header <BIIH (type, client_id, packet_id, data_size). Designed for quick interactive command execution rather than persistent implant management.

Framework 4: FastAPI C2 -- Port 8000

The most operationally active framework. The root path serves a fake multilingual news site called "ArenaReport" as a social engineering lure. Behind this facade, the FastAPI application exposes C2 endpoints:

• /redirect, /sort -- Request processors
• /deliver, /deliver/0 through /deliver/6 -- Multi-stage payload delivery
• Swagger documentation exposed at /docs and /redoc
• Full OpenAPI specification at /openapi.json

Framework 5: Sliver C2 -- Port 31337

BishopFox's Sliver adversary simulation framework, running on the iconic "elite" port. This was not documented in any prior reporting on this infrastructure. Sliver provides cross-platform implant generation, mTLS/WireGuard/HTTPS C2 channels, process injection, and SOCKS5 proxy pivoting -- a significant capability upgrade over the custom Python frameworks.

Weaponized CVE Exploits

CVE-2024-55591: FortiOS Authentication Bypass (CVSS 9.6)

File: POC_ZZ_1.py -- a weaponized modification of watchTowr Labs' public proof-of-concept

This is not a generic exploit. The script contains 13 hardcoded test payloads with victim-specific data from at least two Israeli organizations, developed iteratively as the operator learned FortiOS CLI syntax against live targets.

The exploit chains four issues: unauthenticated WebSocket access to /ws/cli/open, token validation failure (any value accepted for local_access_token), a race condition in the WebSocket-to-Telnet bridge, and unrestricted access profile selection. The active payload (test11) creates a system administrator named FortiSetup with super_admin privileges:

config system admin
edit "FortiSetup"
    set accprofile "super_admin"
    set vdom "root"
    set password ENC SH2x6nU4ztieZPUfFQpYaZY99xC3x4+7RFlL7+pkVYA/sW6Dd53lNOCATA3vbs=
next
end

Named Israeli VPN users exposed in the exploit code:

VPN Group ssl-vpn-groupamoss (Victim 1): shachar, sigal, amos, sima, user1, ahamd, lev, gabi, roy

VPN Group VPN-Users (Victim 2 -- Agentek): dudi, itzikd, maayan, office, ram, roi, snirdyce, tzivya, admin, pazit, Hadar, ronen, talr, yarden, erez, lior

The email address offices@agentek.co.il in test13 ties Victim 2 to Agentek (1987) Ltd., an Israeli scientific instruments distributor based in Yakum, Israel. The operator also created rogue VPN accounts (FortiWiFi, darlen) and injected them into the legitimate VPN groups -- a direct continuation of the FortiGate exploitation TTP documented in CISA advisory AA21-321A for Iranian APT actors.

The source IP 194.11.246.101:1338 in the login message (replacing the original PoC's 13.37.13.37:1337 placeholder) represents the operator's connection point or audit log spoof.

CVE-2026-1281: Ivanti EPMM Pre-Auth RCE

Custom Nuclei template exploiting command injection via /mifs/c/appstore/fob/. The operator conducted mass scanning against 740,000+ target IPs stored in kaka.txt, with results in multiple epmmoutput*.txt files showing hundreds of vulnerable hosts. Callback configured to 157.20.182.49:9090.

CVE-2025-5777: Citrix NetScaler Memory Leak (NMDC Group Targeting)

File: nmdc.py -- memory disclosure via /p/u/doAuthentication.do extracting Basic Auth credentials.

Three hardcoded UAE targets:

• 213.42.174.200 -- resolves to npcc.ae (NPCC, Abu Dhabi)
• 5.195.34.130 -- resolves to nmdc-group.com (NMDC Group, Dubai)
• 151.253.155.74 -- resolves to npcc.ae

NMDC Group PJSC is Abu Dhabi's premier marine/energy contractor with $7B+ annual revenue, 18,000+ employees, and a $17B project backlog. The company is 68.5% owned by Abu Dhabi sovereign entities. Targeting NMDC provides intelligence on Strait of Hormuz maritime infrastructure -- port depths, channel dimensions, seabed composition -- directly relevant to Iranian naval planning during the 2026 crisis escalation.

CVE-2025-54068: Laravel Livewire RCE

Three-stage Nuclei template for deserialization attacks on Livewire v3, deployed against 800+ IPs from target lists.

Additional CVEs

• CVE-2024-23113 -- FortiGate format string vulnerability (cloned from GitHub)
• CVE-2026-21858, CVE-2026-21859, CVE-2026-22200, CVE-2026-23550, CVE-2026-23760 -- Custom Nuclei scanning templates for 2026-era vulnerabilities

785 GB of Exfiltrated Nation-State Data

The investigation uncovered a Put.io account (username: Comata, email: Tumolice@outlook.com) containing 785 GB of stolen data from at least five sovereign targets. Four folders were actively updated on the day of investigation.

Victim	Country	Data Type	Size	Last Updated

A Robocopy log revealed the automated pipeline:

Source: \\10.133.5.32\C$\Users\mofa\Downloads\
Filters: *.pdf, *.docx (last 24 hours only)
Destination: Put.io via rclone

The KKTC_FILES folder received 47 new PDFs on the day of investigation -- numbered government documents (128.pdf, 129.pdf, 243.pdf) indicating automated daily exfiltration from a TRNC document management system.

Credential Harvesting at Scale

OWA Brute Force Campaigns

The investigation cataloged ~453 compromised or targeted accounts across multiple organizations:

Bavaria Egypt (mail.bavaria.com.eg): 37 confirmed logins. Passwords were overwhelmingly P@ssw0rd (34 accounts) and 123456 (4 accounts).

Intercom Enterprises (mail.intercom.com.eg): 143 confirmed logins -- the largest single-organization breach.

Additional Egyptian targets: mail.sinotharwa.com.eg (confirmed credentials), email.egyptair.com (Egyptian national airline -- targeted).

Israeli targets (jojo/ directory): OWA servers across Israeli IP ranges (62.90.216.x, 147.235.x.x, 84.110.x.x) with domain prefix terem\ and 123 targeted usernames.

Portuguese Government Compromise

An active Neo-reGeorg webshell was deployed at:

https://mail.sef.pt/aspnet_client/system_web/4_0_30319/nfud.aspx

SEF (Servico de Estrangeiros e Fronteiras) is the Portuguese Immigration and Borders Service. The tunnel key 123QWEasd was found in bash history. Additional investigation revealed a compromise of RNSI -- Portugal's national internal security network and the COOPINT police cooperation database -- with 37.3 GB of data exfiltrated to Put.io.

Cross-Ecosystem Tool Sharing: The Tsundere Botnet Connection

The Unexpected Finding

The file reset.ps1 on MuddyWater's server is not MuddyWater malware. It is a Tsundere Botnet dropper -- a 2.2 MB heavily obfuscated PowerShell script attributed by Kaspersky GReAT to Russian-speaking threat actor "koneko."

The dropper downloads Node.js v18.17.0 from nodejs.org, installs to %USERPROFILE%\AppData\Local\Nodejs, and deploys an AES-256-CBC encrypted JavaScript payload (sysuu2etiprun.js). The bot then resolves its C2 address by querying an Ethereum smart contract on the public blockchain.

This means MuddyWater operators are acquiring tools from Russian cybercrime marketplaces and deploying them alongside their custom Iranian toolset. This pattern -- state-sponsored APTs purchasing commercial cybercrime tools -- is increasingly observed in the threat landscape, and this is one of the clearest examples.

Tsundere Netto v2.4.4 Panel

The C2 at 185.236.25[.]119 hosts a full cybercrime-as-a-service platform:

• 40+ REST API endpoints extracted from client-side JavaScript bundles
• Bot commands: /eval (arbitrary JS execution), /cmd (system command), /download_and_run, /screenshot
• Monero wallet integration for marketplace payments
• Build system for MSI and PowerShell payload generation
• SOCKS proxy service converting bots into tunnel nodes
• Open registration -- anyone can create an account
• Marketplace where threat actors buy/sell botnet access

Blockchain C2: Unkillable Infrastructure

The Tsundere botnet uses an Ethereum smart contract disguised as an ERC-20 token called "MisakaNetwork" to store and rotate C2 addresses on the public blockchain:

Contract: 0xa1b40044EBc2794f207D45143Bd82a1B86156c6b Deployed: 2024-09-23

The contract exposes two custom functions alongside standard ERC-20 methods:

• setString(string _url) (selector 0x7fcaf666) -- stores a C2 URL mapped to the caller's wallet
• getString(address) (selector 0x7d434425) -- retrieves the current C2 URL for a given wallet

To check the current active C2:

curl -s -X POST https://ethereum-rpc.publicnode.com \
  -H "Content-Type: application/json" \
  -d '{"jsonrpc":"2.0","method":"eth_call","params":[{
    "to":"0xa1b40044EBc2794f207D45143Bd82a1B86156c6b",
    "data":"0x7d43442500000000000000000000000073625B6cdFECC81A4899D221C732E1f73e504a32"
  },"latest"],"id":1}'

26 transactions across 7 operator wallets revealed a complete C2 rotation timeline spanning from September 2024 to November 2025, with 15+ unique C2 IP addresses. The protocol evolved from HTTP to WebSocket around April 2025, and ports standardized to 1234 and 3011.

One wallet set its C2 value to https://fbi.gov -- a troll entry characteristic of Russian cybercriminal culture. Fund flow analysis proved this "troll wallet" is controlled by the same entity as the primary operator through a pass-through wallet chain.

A second smart contract was also discovered at 0x376Ae40709C35f47ee7FA22F310D1368FAA7D21b, created by a wallet directly funded by the primary operator. This test contract pointed to ws://104.219.234.251:3001 -- a DataWagon LLC server in Buffalo, NY with hostname root2.jemex.sk, linking to the JemexShop cybercriminal marketplace infrastructure.

Multi-Operator Team Structure

Bash history and the directory structure reveal at least five operator workspaces, suggesting a team operation with specialized roles:

Workspace	Activity
im/	Flask C2 development, OWA credential spraying, Laravel exploits, ICMP tunneling
jojo/	Israeli targeting, OWA brute force against .co.il domains, credential collection
sam/	ServerCopy C2 framework, AES encryption, macro-based stagers
moz/	Additional operations (limited visibility)
sa/	Automated subdomain reconnaissance (autorec/)

Attribution Indicators

• Farsi code comment in encryptions.py: "تبدیل string به bytes" ("convert string to bytes")
• Accidental Farsi keyboard input in bash history: "فئعط مس", "سعیخ"
• Persian calendar files on operator desktop: bahman.txt, esfand.txt
• Targeting pattern: Israel, Egypt, UAE, Portugal, Northern Cyprus -- consistent with MOIS collection requirements
• Tool overlap with documented MuddyWater campaigns: UDPGangster (FortiGuard Labs), DLL sideloading (FMAPP.exe + FMAPP.dll), OWA credential spraying, custom C2 frameworks, Neo-reGeorg tunneling

Defensive Recommendations

Immediate Actions

1. Block all network IOCs listed above at the firewall and proxy level. Pay particular attention to UDP port 1269 traffic (UDPGangster).

2. Hunt for Neo-reGeorg webshells in IIS/Exchange environments. Search for the path pattern /aspnet_client/system_web/*/nfud.aspx and related variants.

3. Audit FortiGate appliances for rogue administrator accounts named FortiSetup, FortiWiFi, FortiAdmin, or darlen. Verify all VPN group memberships. Patch CVE-2024-55591 immediately if running FortiOS 7.0.0-7.0.16.

4. Audit Ivanti EPMM instances for exploitation of CVE-2026-1281 via the /mifs/c/appstore/fob/ endpoint. Check web logs for callbacks to 157.20.182.49:9090.

5. Audit Citrix NetScaler appliances for memory leak exploitation via /p/u/doAuthentication.do.

Detection Engineering

6. Monitor for Ethereum RPC calls from internal hosts. Bots query public Ethereum nodes to resolve the smart contract C2 address. Detection rule: internal hosts making eth_call requests to public RPC endpoints (publicnode.com, infura.io, alchemy.com) with the contract address 0xa1b40044... in the data field.

7. Monitor for WebSocket connections to the listed C2 IPs, particularly on ports 1234 and 3011.

8. File system monitoring: Alert on creation of %APPDATA%\Local\NodeJS\ or %APPDATA%\Local\nodejs\ directories. Alert on execution of sysuu2etiprun.js or any Node.js process spawned from these paths.

9. Network signatures: HTTP POST requests to /deliver/0 through /deliver/6 on port 8000. XOR-encrypted + Base64-encoded traffic with key mysecretkey.

Cloud and Credential Security

10. Rotate all credentials if your organization uses OWA with passwords matching P@ssw0rd or 123456. Enforce multi-factor authentication.

11. Cloud providers: Wasabi should investigate bucket wasabirclone (access key: APPME47OSTD6I82XCQMT). Put.io should investigate token 3PHNZWTMJ642BHNQPE2W. Shodan should revoke API key MijnMaksNo4GCF6KlnWBbh52VMC47Hxm.

Strategic Monitoring

12. Monitor the Ethereum smart contract for C2 rotations. The function selector 0x7fcaf666 (setString) called against the contract address indicates a C2 address change. This provides real-time visibility into Tsundere infrastructure rotation.

Conclusion

This investigation documents one of the most comprehensive windows into a state-sponsored APT's operational infrastructure that has been publicly available via OSINT. The accidental exposure of a /root home directory revealed not just tools and capabilities, but the full operational workflow of an active Iranian APT campaign: from reconnaissance (Shodan EDU account with 200K credits) to initial access (six weaponized CVEs, OWA credential spraying) to C2 management (five frameworks running simultaneously) to data exfiltration (785 GB across cloud storage accounts, actively updated daily).

Three findings stand out for broader threat intelligence:

First, the cross-ecosystem connection between MuddyWater and the Russian-operated Tsundere Botnet demonstrates that state-sponsored APTs are actively purchasing tools from cybercrime-as-a-service marketplaces. The presence of the Tsundere dropper (reset.ps1) alongside custom Iranian C2 frameworks on the same server, combined with zero infrastructure overlap between the two actors' hosting providers, strongly supports tool acquisition rather than operational partnership.

Second, the Ethereum blockchain-based C2 resolution used by Tsundere represents a maturing trend in censorship-resistant infrastructure. The smart contract cannot be taken down by traditional means -- it is replicated across thousands of Ethereum nodes. C2 rotation costs only a small gas fee. Defenders must monitor blockchain RPC activity from endpoints as part of their detection strategy.

Third, the scale of data exfiltration -- 785 GB from five sovereign targets with automated daily operations -- underscores that Iranian APT campaigns are conducting sustained intelligence collection operations, not one-off intrusions. The targeting of NMDC Group's marine/energy infrastructure in the context of the 2026 Strait of Hormuz crisis demonstrates direct alignment between cyber operations and geopolitical objectives.

The operator's 14 critical OPSEC failures gave us this visibility. Next time, they may not make the same mistakes.
