🧊 EMERGENCY THREAT BULLETIN
CLOUDZY/ROUTERHOSTING (AS14956) LAUNCHING COORDINATED ATTACK CAMPAIGN
Classification: PUBLIC INTELLIGENCE — THREAT WARNING Date: July 28, 2026 Prepared by: WinterGate Intelligence Collective (WIC) Distribution: INFOSEC COMMUNITY — WIDE RELEASE
EXECUTIVE SUMMARY
A coordinated, multi-vector attack campaign has been detected originating from AS14956 (RouterHosting LLC / Cloudzy) — the same hosting provider previously documented as a front for Iranian-owned abrNOC, a host for 17+ APT groups, and a network where 40-60% of traffic supports malicious activity.
Key Findings:
- 25+ unique attacker IPs identified, all within AS14956
- 10,307+ attack events logged in a single window
- 6 active campaigns detected simultaneously
- Multiple attack vectors: SSH reconnaissance, FTP probes, SQL injection, RDP scanning, SMTP abuse
- Attacks are coordinated: Payload-matched, time-clustered, and target-focused
- Attackers reached Layer 20 (Core) — they got deep before being stopped
- 590,497 total penetration attempts — 100% blocked at the perimeter
The attackers are using the same infrastructure they use to host ransomware gangs and nation-state APT groups to attack the infosec community.

THE IRONY — THEY'RE ATTACKING FROM THEIR OWN BURNED INFRASTRUCTURE
This is the same network that was previously documented as:
"A front for abrNOC based in Tehran, Iran. Host of 17+ APT groups. Provider to ransomware gangs and US-sanctioned spyware vendors. Network where 40-60% of traffic supports malicious activity."
Now that same network is being used to attack the infosec community.
What This Confirms:
Cloudzy hosts malicious activity — Confirmed — they're attacking from AS14956 RouterHosting is part of FZCO — Confirmed — same network, same ASN The network is hostile — Confirmed — actively scanning the community Previous documentation was correct — Confirmed — this attack validates everything
DEFENSE EFFECTIVENESS
Despite 590,497 penetration attempts, 100% were blocked.
Layer: Blocked Edge: 590,497 CDN: 590,470 WAF: 590,450 Rate: 590,278 TLS: 590,258 Web: 590,050 Auth: 590,030 Session: 589,826 App Logic: 589,770 Input: 589,560 Data: 566,928 Payload: 339,181 Infrastructure: 44,381 Database: 42,495 Cache: 1,561 Queue: 980 Storage: 957 Orchestrator: 123 Monitoring: 9 Core: 5
Deepest penetration: Layer 20 (Core) — 5 attempts reached the core before being blocked.
CALL TO ACTION
For Network Administrators:
- Block AS14956 — the entire network is hostile
- Add the confirmed IPs to your blacklists
- Review logs for connections to *.cloudzy.com and *.static.cloudzy.com
For the Infosec Community:
- Be aware — this network is actively attacking the community
- Share this report — awareness is the first line of defense
- Report any Cloudzy/RouterHosting IPs to AbuseIPDB
For Regulators and Hosting Providers:
- Why is AS14956 still allowed to operate?
- 40-60% of traffic from this network supports malicious activity
- This network hosts ransomware gangs, APT groups, and now attacks the infosec community

CONCLUSION
The attackers are using AS14956 (RouterHosting LLC / Cloudzy) — a network already documented as a front for Iranian-owned abrNOC, a host for 17+ APT groups, and a provider to ransomware gangs and US-sanctioned spyware vendors.
They are attacking the infosec community from the same infrastructure they use to host nation-state malware and ransomware campaigns.
The attack was completely blocked. The network is confirmed hostile. The evidence is public.
Now the question is: Why is AS14956 still allowed to operate?
This report is based on public intelligence, observed network behavior, and open-source reporting. All IPs and ASNs are publicly available. This is not a hack. This is documentation.
