Threat researchers identified three criminal ecosystems hiding behind visually similar casino and adult websites: Chinese-language illegal gambling and money-laundering operations, fraudulent “scambling” platforms, and decoy sites hosting PeckBirdy malware command-and-control (C2) infrastructure. The Chinese-language gambling ecosystem spans more than 1.7 million domains and includes the FUNNULL CDN, Vigorish Viper, and Sable Squirrel networks; Sable Squirrel alone reportedly controls roughly 10,000 drop-caught expired domains, has spent more than $7 million acquiring them, and has been linked to 405 C2 domains and more than 31,000 malware samples communicating with its infrastructure. China-aligned actors have used PeckBirdy since 2023, embedding JavaScript and WebSocket C2 services in low-quality casino and adult sites, including cache-cdn[.]org, cache-mcp[.]com, mcp-source[.]online, and githubassets[.]net.
Separate scam-gambling networks use polished gaming and wagering sites promoted through Discord and social media, often advertising fraudulent $2,500 celebrity-linked credits. Victims can place simulated bets and see fabricated winnings, but withdrawals trigger demands for cryptocurrency “verification deposits” and further payments that never result in a payout. Researchers linked at least 1,270 recently registered domains to one centrally managed operation through shared code, tracking, support infrastructure, and chatbot credentials; affiliates have also expanded this scalable scam model. Organizations should treat casino or adult-domain DNS activity as a potential security signal rather than solely a policy issue, especially where endpoints resolve multiple distinct PeckBirdy-related domains.

8 events from the most recent confirmed update back to the earliest known activity.
As of August 31, cache-cdn[.]org had 13 VirusTotal detections, cache-mcp[.]com had three, and mcp-source[.]online had none. The domains were associated with PeckBirdy JavaScript and WebSocket C2 infrastructure hidden behind casino and adult-site decoys.
The United Nations Office on Drugs and Crime assessed that illegal online gambling had become a primary revenue source and operational enabler for organized crime in Southeast Asia, estimating global illegal betting revenue at up to $1.7 trillion annually.
Brian Krebs documented a cryptocurrency scam network using more than 1,200 polished gaming and wagering websites promoted through Discord and social media. The sites used a shared chatbot API key and lured victims with fake promotional credits before demanding nonrefundable cryptocurrency deposits for withdrawals.
The Philippines blocked more than 7,000 illegal gambling websites, though operators rapidly rotated domains and limited the measure's effectiveness.
China-aligned APT actors began using the PeckBirdy framework to conceal malware command-and-control infrastructure in Chinese-language casino decoy websites. The framework has targeted corporate and government organizations across Asia.
China's March 2021 criminal-law amendment prohibited operating overseas gambling establishments and organizing or soliciting Chinese residents to use them.
Infoblox identified Sable Squirrel as a large expired-domain acquisition campaign reportedly controlling about 10,000 domains and spending more than $7 million acquiring them. Researchers confirmed 405 of its domains as malware C2 infrastructure and found more than 31,000 malware samples communicating with its infrastructure.
Infoblox distinguished illegal Chinese-language gambling and money-laundering sites, fraudulent "scambling" platforms, and casino or adult-site decoys concealing PeckBirdy C2 infrastructure. Its tracked Chinese-language casino ecosystem contained more than 1.7 million domains, with FUNNULL CDN and Vigorish Viper accounting for about 81% of them.

Infoblox Threat Intel reported that cybercriminals are increasingly exploiting expired "dropcatch" domains as a large-scale abuse channel, with roughly **65,000** re-registered dropped domains observed per day in the first half of 2026—about **20%** of newly seen domains. Because these domains retain backlinks, reputation, residual traffic, and sometimes dangling DNS relationships, attackers can revive them for scams, traffic monetization, malware delivery, and redirection without first compromising new infrastructure. Researchers said actors including **Stuffy Squirrel**, **Shady Squirrel**, and **Swiping Squirrel** collectively control thousands of such domains, using cloaked traffic distribution, ad-tech chains, affiliate programs, and custom injections to steer victims to tech-support scams, gambling offers, **SocGholish**, and other malicious content. The most prominent operation, **Sable Squirrel**, was described as a sprawling network controlling more than **10,000 domains** tied to illegal sports streaming, betting promotion, traffic redirection, and malware command-and-control, with estimated domain spending exceeding **$7 million**. Infoblox identified more than **31,000 malware samples** communicating with Sable Squirrel infrastructure, including **Quasar RAT**, **AsyncRAT**, **DCRat**, **NanoCore**, **Remcos**, **njRAT**, and samples with **HiddenTear** signatures, while some binaries carried the actor’s own brands such as `socolive`, `xoilac`, and `8xbet` in PE metadata. Researchers said the actor repurposed hundreds of streaming domains into dual-use malware infrastructure beginning in late 2025, likely overlapping with the Vietnamese **Xoi Lac TV** ecosystem, and that related actors have also redirected visitors from major media sites and partnered with downstream malware operators such as **TA569** after disruptions to earlier criminal infrastructure.

Researchers reported a large-scale SEO poisoning campaign that hijacked abandoned cloud DNS delegations to publish Thai-language gambling pages on legitimate corporate subdomains belonging to 163 organizations in more than 30 countries. The activity primarily abused orphaned **Azure DNS** zones, though investigators also observed stale configurations involving DigitalOcean, wildcard misconfigurations, and a Verizon-linked cluster with more than 1,000 deceptive `A` records. Victims included government agencies, hospitals, banks, universities, and critical infrastructure providers, and 161 of the 163 organizations were still actively compromised when the findings were published. The operators reclaimed forgotten DNS zones, added wildcard or bulk DNS records, obtained valid **Let’s Encrypt** wildcard certificates, and deployed a consistent **Next.js** gambling kit that made the pages appear trustworthy to users, browsers, and search engines. Investigators linked the infrastructure through shared favicons, redirect paths, certificates, JARM fingerprints, HTTP body hashes, and Chinese-language management artifacts, tracing delivery nodes and a 103-server backend network in Hong Kong that supported affiliate gambling domains and referral codes such as `link99`, `ibiza99vip1`, `bigwinv1`, and `seven77vip1`. The campaign relied on DNS hygiene failures rather than malware or application exploits, with server-side geographic filtering used to redirect Thai users to gambling destinations.

Check Point Research reported that the Chinese-speaking **Gambling Goblin** cybercrime cluster has compromised Brazilian government, educational, and commercial Linux web servers since mid-2025. The operators install malicious Apache modules that covertly reverse-proxy traffic from trusted victim domains to fake Google Play, Microsoft Store, and Amazon-branded gambling and betting pages, abusing the victims’ reputations to manipulate search-engine rankings at scale. The group uses an obfuscated Linux toolkit including DownPro, ChUser, PasswordHarvester, AlphaAgent, oRAT, an SSH brute-forcer, and reconnaissance utilities to steal credentials, maintain persistence, move laterally, and remotely administer compromised hosts. Researchers assess with medium-to-high confidence that Gambling Goblin is linked to **Earth Berberoka**, citing shared oRAT code, Chinese-language artifacts, gambling-focused operations, lookalike-domain techniques, and overlapping Amazon-hosted infrastructure; associated systems also host Vietnamese, Spanish, and English phishing content and generate domains daily, creating capacity to expand internationally or distribute malware.
