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.

7 events from the most recent confirmed update back to the earliest known activity.
A Chinese-speaking cybercrime cluster tracked as Gambling Goblin began compromising internet-facing Linux web servers at Brazilian government, educational, and commercial organizations for gambling-focused SEO fraud and phishing. The operators used malicious Apache modules to reverse-proxy victim-domain traffic to fake Google Play, Microsoft Store, and Amazon-themed betting pages.
ESET assessed that the previously unknown, China-aligned GhostRedirector actor had been active since at least August 2024, compromising Windows servers primarily in Brazil, Thailand, and Vietnam. The group deployed the Rungan backdoor and Gamshen IIS module to manipulate Googlebot-facing responses and promote gambling sites through SEO fraud.
Gurucul published named attacker-controlled domains, SHA-256 hashes, and detection queries associated with Gambling Goblin activity to support threat hunting. The report also characterized the campaign as high severity.
Ctrl-Alt-Intel published a browser-based checker for domains and IPs appearing in preserved evidence from a campaign in which a Chinese actor compromised thousands of WordPress sites. The tool classifies evidence from Targeted through Confirmed and includes web-shell, directory, vulnerable-endpoint, and admin-ajax.php hunting indicators.
Check Point disclosed that Gambling Goblin uses malicious Apache modules that remove security headers while reverse-proxying traffic, alongside DownPro, AlphaAgent, oRAT, a 3snake-derived credential stealer, an SSH brute-forcer, and reconnaissance tooling. The researchers also identified parallel Vietnamese, Spanish, and English phishing networks and infrastructure capable of generating new domains daily.
Check Point Research assessed with medium-to-high confidence that Gambling Goblin is connected to the Chinese-speaking Earth Berberoka cluster. The assessment cited overlaps including oRAT, Chinese-language strings, and infrastructure and domains resembling trusted technology brands.
Hunt.io reported that more than 630,000 URLs on gov.br subdomains were leveraged for black-hat SEO redirect activity. This provides a quantified scale for abuse affecting Brazilian government domains.

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.

Researchers reported that the newly identified APT group **Earth Berberoka** has targeted gambling websites using a mix of older tools and a cross-platform **oRAT** remote access trojan, including a macOS variant written in Go. The campaign used a fake **Bitget** application delivered as an unsigned disk image, with a package installer that relied on a `preinstall` script to drop and launch the malware from `/tmp`, indicating an effort to blend social engineering with lightweight macOS tradecraft. Analysis of the macOS sample showed a **UPX**-packed Go binary with an encrypted configuration blob appended to the file and decrypted at runtime to recover command-and-control settings. The malware supports multiple communication modes, including **TCP**, **STCP**, and **SUDP**, and uses **smux** and **QUIC** for networking while beaconing to its C2 every five seconds. Once active, oRAT can transfer files, provide shell access, proxy traffic, scan ports, capture screenshots, and delete itself, underscoring a capable espionage toolset despite the comparatively unsophisticated delivery chain.

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.
