Executive Summary
On the same AS215659 that hosts the Satanist/2cb.su network, a Dutch IT firm called Bronk-ICT operates 28 verified Tor relays contributing approximately 2.4% of the entire Tor network's consensus weight. This investigation traces the supply chain that connects both operations โ a Croatian technology group called MAXKO that provisions infrastructure to both parties โ and a Romanian shell company called Internet Magnate (Pty) Ltd whose operator publicly exposed his own infrastructure on hosting forums.
The critical finding: Bronk's April 2026 relay configurations explicitly list 2cb.su fingerprints in their MyFamily declaration. This is not correlation โ this is configuration. Someone typed those specific hexadecimal relay identifiers into Bronk's torrc file. The question is whether this constitutes coordination or precaution.
I. The Website
bronk-ict.nl is a Laravel application running on nginx 1.29.4 and PHP 8.4.18, hosted at 149.210.164.144 (Signet B.V., AS20857, Netherlands). The site identifies a sole proprietor โ initials D.O. Bronk โ offering software development services in C, C++, C#, Python, Delphi, and SQL alongside web development with Vue and Laravel.
"Operating tor (exit) relays in 6 countries, 15 servers, 20+ nodes."
"Contact / Abuse: tor-relay@bronk-ict.nl"
This is extraordinary for the Tor ecosystem. Most relay operators maintain strict pseudonymity. Bronk-ICT publicly declares its operation with a real domain, a real abuse contact, and a real business identity. Furthermore, the relays are verified through CIISS v2 (proof:dns-rsa) โ a cryptographic protocol that proves the operator controls the DNS records of bronk-ict.nl. This is the gold standard of Tor operator identity verification.
The website's server (149.210.164.144) also hosts the mx1.bronk-ict.nl mail exchange record, meaning the company's actual email infrastructure runs on the same hardware that serves the website and at least one Tor relay. This is characteristic of a real, resource-constrained business โ not a well-funded front operation that would provision separate infrastructure.
II. The Network: 28 Relays, 8 ASNs, 9 Countries
OrNetStats โ the authoritative Tor relay verification service โ lists 28 proven relays for bronk-ict.nl. The distribution across providers is unusual in both its diversity and its scale:
| Provider (ASN) | Country | Relays | Role | Est. CW |
|---|---|---|---|---|
| ATW Internet Kft (AS41075) | Hungary | 5 | Guard | ~274,000 |
| Aokigahara/Kyun (AS215659) | Romania + US | 7 | Exit + Guard | ~105,000 |
| MAXKO d.o.o. (AS211619) | Croatia + Hungary + Bulgaria | 6 | Exit + Guard | ~50,000 |
| Maxko Gaming (AS329325) | South Africa | 2 | Exit | ~18,000 |
| Signet B.V. (AS20857) | Netherlands | 3 | Exit + Guard | ~15,000 |
| RoyaleHosting (AS212477) | Netherlands | 1 | Exit | ~8,000 |
| OVH SAS (AS16276) | Singapore | 2 | Guard | ~4,000 |
| M247 (AS9009) | Japan + Netherlands | 2 | Guard | ~3,000 |
The eight-ASN diversity is significant. A coordinated malicious operation (traffic correlation, MitM) would typically minimize complexity by using one or two providers. Bronk has deliberately spread across providers with different jurisdictions, BGP policies, and ownership structures. This is textbook Tor operational diversity โ protecting against a single point of censorship or seizure.
Technical Sophistication Markers
- FreeBSD: 4 relays run FreeBSD (BronkOnFreeBSD, USABSDBronk, two others). Only ~9.3% of Tor relays use BSD โ this indicates genuine systems expertise.
- obfs4 Bridge: BronkOBridge (first seen May 31, 2026) is a pluggable transport bridge for censorship circumvention. Adversarial actors have zero use for bridges.
- IPv6 Support: Multiple relays serve IPv6 ORPorts โ considered best practice, indicating infrastructure care.
- Variable Exit Policies: Exit policies vary by relay (conservative SMTP-blocking to permissive web-only). This suggests individual per-relay configuration, not mass-deployed templates.
- No BadExit Flags: Zero instances of Tor directory authorities flagging Bronk relays for malicious traffic manipulation.
III. The Timeline: December 2025 Through June 2026
Previous analysis assumed Bronk launched April 6, 2026 โ the same day as the coordinated 2cb.su deployment. OrNetStats corrects this:
| Date | Event | Significance |
|---|---|---|
| Dec 18, 2025 | drskaffa relay launched (Signet B.V., NL) | First Bronk relay โ 3.5 months before April mass-launch |
| Dec 23-30, 2025 | Netherlands expansion (intospace, dobronk) | Early growth on Dutch infrastructure |
| Jan 2026 | Multi-country expansion | MAXKO (HR/HU/BG), ATW (HU), Kyun (RO/US) added |
| Apr 4, 2026 | BronkOBridge server starts | FreeBSD bridge on RoyaleHosting |
| Apr 6, 2026 | Onionoo "first_seen" for AS215659 relays | Measurement artifact โ Bronk was already established |
| Apr-May 2026 | 2cb.su/Satanist relays go offline | All 10 fingerprints in Bronk's alleged_family die |
| May 10-13, 2026 | Wave 2: SABronk, BronkJohannesbrg, Asia | NEW torrc template WITHOUT 2cb.su fingerprints |
| May 31, 2026 | BronkOBridge registered in BridgeDB | obfs4 censorship circumvention โ genuine intent signal |
| Jun 10, 2026 | dobronk relay on Signet | Expansion/replacement activity |
| Jun 19, 2026 | Bulgaria relays go offline | MoreBulgaria + BulgarianBronkA1 (AS211619) โ unknown reason |
IV. The MAXKO Thread
MAXKO d.o.o. is a Croatian technology group founded in 2014 in Sisak. Through its holding structure, it operates:
- AS211619 (Europe) โ ISP covering Croatia, Hungary, Bulgaria
- AS329325 (Africa) โ via subsidiary "Maxko for Gaming Development LLC" registered with AFRINIC
- Aokigahara SRL sponsorship โ MAXKO's Croatian LIR (mnt-hr-maxko-1) sponsors Aokigahara's RIPE membership
MAXKO is not a simple hosting provider. Its portfolio includes:
- Software development (custom apps, business automation)
- Game development (Asteidus MMORPG)
- Blockchain integration (eMAX token on Polygon/MATIC chain)
- Global hosting infrastructure (6 data center locations)
"MAXKO Hosting is part of MAXKO group, founded in Sisak, Croatia, in 2014. ISP managing its own IP ranges via AS211619 (Europe) and AS329325 (Africa). Data-centre presence in Croatia, Hungary, Bulgaria, Egypt and South Africa."
The critical finding: MAXKO is the common supply chain. Both D.O. Bronk and the 2cb.su/Satanist operator purchase infrastructure from the same Croatian technology group. This is the ONLY overlapping set of ASNs between Bronk's eight providers and 2cb.su's known infrastructure:
Whether MAXKO knowingly provisions both operations or is simply Tor-friendly commodity hosting remains an open question. The blockchain and gaming diversification suggests a company comfortable with privacy-adjacent technology. The sponsorship of Aokigahara SRL โ a company named after Japan's "Suicide Forest" โ suggests at minimum a tolerance for unconventional branding.
V. The Romanian Layer: Five Cyber Host and Internet Magnate
Bronk operates four relays on IP addresses in the 93.113.25.x range, assigned to AS214209 โ registered to Internet Magnate (Pty) Ltd, ostensibly a South African company. The truth is more interesting.
Five Cyber Host Security SRL
Incorporated: October 14, 2019
Address: Str. Eternitatii Nr.14, Scrioaศtea, Jud. Teleorman, Romania
Activity: Data processing, web page administration
ASN: AS210718 (five-cyber-host-security-as)
Operator: "Calin" (first name only, from forum posts)
Internet Magnate (Pty) Ltd โ The Shell
AS214209, registered September 12, 2024 (20 months old at time of writing)
Address (RIPE): Tudor Vladimirescu nr 60, Orastie, Romania
Address (RIPE alternate): 1 Bondev Drive, Centurion, GAUTENG, South Africa
magnates.co.za โ 93.115.101.8 โ FIVE_CYBER_HOST_SECURITY_SRL netblock
SMTP: dweb.five-host.com
NO MX records โ abuse email (reports@magnates.co.za) is non-functional
The LowEndSpirit hosting forum thread from October 2024 is revelatory. In a discussion about his new 100Gbps test servers, Calin provides magnates.co.za as the abuse contact. Community members immediately identify the game:
"What you are doing is smart when you don't tell anyone about it. I suppose someone told you to use a shell company for an ASN to not attract attention, but you blow the cover up by talking about it in public."
"So, transfer to Africa finished. Noice. Now shady grady will take a leap!"
"Clearly a shell company founded in 2024, not 7 years ago. Domain is 41 days old."
Calin's known operational profile includes:
- Hosting illegal IPTV streaming services
- Publicly bragging about ignoring DMCA takedown requests
- Creating Internet Magnate specifically to move IP space to a jurisdiction with lax enforcement
- Operating infrastructure where abuse reports disappear (no functional MX records)
VI. The MyFamily Configuration: The Smoking Gun
This is the central finding of this investigation. In the Tor relay ecosystem, the MyFamily
configuration in torrc tells directory authorities that certain relays are operated by the same entity. When
Relay A lists Relay B in its MyFamily, the Tor client will avoid selecting both in the same circuit โ preventing
traffic correlation by a single operator.
Bronk's Wave 1 relays (launched April 6, 2026) contain the following in their alleged_family
field โ Tor's public record of what a relay has declared:
Contains 10 fingerprints that correspond to OFFLINE relays. These fingerprints are NOT part of Bronk's own relay set. Cross-reference with prior dossier data identifies them as the 2cb.su/Satanist relays documented in TI-2026-030D.
Wave 2 relays (May 10+) do NOT contain these fingerprints โ a new configuration template was used after 2cb.su went offline.
Three Interpretations
| Interpretation | What It Implies | Assessment |
|---|---|---|
| Defensive Declaration | Bronk discovered 2cb.su as co-hosted neighbor and proactively added them to prevent client circuit co-selection. Responsible operator behavior. | Most consistent with evidence: asymmetric (one-way), removed after 2cb.su died, matches sophisticated operator profile |
| Prior Coordination | Bronk was given the fingerprints by the 2cb.su operator before launch, implying at minimum communication between the two parties. | Possible: requires pre-launch knowledge of specific hex fingerprints. But asymmetry argues against same operator. |
| Same Operator | Bronk and 2cb.su are the same person/group using different identities. | Weakest: if same operator, they would configure MUTUAL family (both ways). The asymmetry is inconsistent. |
VII. The Legitimacy Paradox
The evidence presents a paradox. Every individual indicator points to legitimacy:
- Real Dutch business identity (KvK-registered, presumably)
- Cryptographic domain proof (DNS-RSA)
- Public website with Tor disclosure
- Functional abuse contact
- 8-ASN diversity (expensive, complex)
- obfs4 bridge (anti-censorship purpose only)
- FreeBSD expertise
- No BadExit flags
- Variable exit policies (individual relay care)
- Mail server co-location (real business infrastructure)
But this legitimacy operates on infrastructure layers specifically designed for unaccountability:
- Aokigahara SRL โ named after the "Suicide Forest," sponsored by a Croatian gaming conglomerate
- Internet Magnate โ South African shell with non-functional abuse email
- MAXKO โ common supply chain with a Satanist-themed criminal network
- Snel.com โ accepts Monero payments (financial untraceability)
- RoyaleHosting โ known bulletproof hosting forum darling
The paradox is not that these are contradictory โ they are not. A legitimate privacy advocate would deliberately choose providers that resist third-party pressure. The same hosting that enables criminal infrastructure also enables the infrastructure that protects dissidents, journalists, and abuse survivors. This is the fundamental design of Tor, expressed at the hosting layer.
The Scale Question
Running โฌ12,000-24,000 per year in Tor infrastructure without visible external funding raises questions. For comparison:
- Cyberology (world #1 exit): operates its own AS, commercial model
- Torservers.net: nonprofit foundation with public fundraising
- Neel Chauhan: individual relay operator funded through donations
- Bronk-ICT: sole proprietor, no visible funding, no public fundraising
The mx1/mx2 hostnames on Bronk's Netherlands relays suggest the simplest answer: the same servers run real business services (email, hosting for clients) alongside Tor relays. The marginal cost of adding Tor to existing infrastructure is much lower than dedicated hosting โ perhaps โฌ5-8K/year incremental rather than the full โฌ12-24K estimate.

IX. Assessment
| Hypothesis | Confidence | Key Evidence |
|---|---|---|
| Legitimate independent Dutch Tor operator | 75-80% | 8-ASN diversity, DNS-RSA proof, public identity, bridge operation, no BadExit, asymmetric MyFamily, 3-month prior operation |
| Coordinated actor / front organization | 15-20% | MyFamily listing requires specific fingerprint knowledge, same ASN choice, high funding with no visible revenue, low public profile |
| Unwitting co-optation | 5-10% | Legitimate operator using Kyun without knowing about Satanist co-tenant; MyFamily as defensive measure |
X. Gaps and Open Questions
- KvK registration: Dutch business register lookup would confirm legal entity form, owner full name, and registration date. Requires paid API access.
- Full name: "D.O. Bronk" โ initials only. No LinkedIn profile found. The surname is uncommon in the Netherlands.
- Funding model: No evidence of Tor Project grants, foundation support, or commercial relay revenue. Self-funded from IT consulting income?
- 2cb.su fingerprint timing: Did Bronk list the fingerprints before or after 2cb.su appeared on AS215659? The chronological sequence determines whether this is coordination or reaction.
- Bulgaria relay deaths: Why did MoreBulgaria and BulgarianBronkA1 go offline June 19? Provider issue, payment failure, or deliberate?
- tor-relays mailing list: Whether Bronk has posted to the community mailing list remains unchecked due to rate limits.
- MAXKO relationship: Is MAXKO Tor-friendly by commercial policy, or is there a deeper relationship?
Methodology: Passive reconnaissance only. No active scanning of Bronk infrastructure. All data from public sources or pre-existing honeypot/enrichment databases. Cross-corpus vectorized search across existing dossiers for relationship discovery.
