A sophisticated black-hat SEO poisoning campaign has compromised over 150 Indian government websites and financial institutions, redirecting millions of users to fraudulent gambling platforms promoting rummy and high-risk “investment” games.
The operation, exploits vulnerabilities in government portals (.gov.in) and educational domains (.ac.in), leveraging search engine manipulation to siphon users toward scam websites.
Exploiting Trusted Domains
Threat actors injected malicious JavaScript code into vulnerable government websites, including state portals, to hijack search engine rankings.
The script identifies traffic originating from search engines like Google and redirects mobile users to gambling platforms such as indorummy[.]net and teenpattionline[.]game, while displaying error pages to desktop users to evade detection.
One compromised Kerala government webpage, for instance, was altered to include hidden keywords like “instant personal loans” and “low-interest credit cards” tied to major Indian banks.
Users searching for legitimate financial services are funneled to pages promoting rummy games disguised as “investment opportunities”.
Analysts found over 12,000 spam pages leveraging .shtml and .aspx file uploads on government servers, with content mirroring Indonesian casino templates to bypass regional filters.
Technical Tactics
The campaign employs multi-layered evasion tactics:
- Referrer Header Manipulation: Scripts check if visitors arrive via search engines, redirecting only those users to gambling sites.
- User-Agent Cloaking: Mobile users receive gambling links, while desktop users see 404 errors to avoid raising suspicion1.
- Keyword Stuffing: Compromised pages embed trending financial terms (e.g., “PPF account,” “fixed deposit rates”) to dominate search results.
Attackers host malicious domains through Cloudflare’s CDN and AWS infrastructure, masking their origin servers.
Domains like rummydeity[.]cc and crickexlive[.]vip resolve to IPs in Cloudflare’s 104.21.x.x range, complicating takedown efforts.
Secondary domains hosted on Amazon Web Services (18.160.46.x) further disperse the infrastructure, with phishing kits mimicking legitimate banking portals.
Financial and Social Impact on Indian Users
The scam capitalizes on India’s online gambling boom, luring users with fake “referral bonuses” (₹20–80 per sign-up) and “VIP tiers” promising higher returns.
Victims must deposit funds to withdraw earnings, a hallmark of Ponzi schemes. CloudSEK’s analysis of indorummy[.]net revealed embedded SMS phishing templates and fake customer service chatbots that harvest financial data.

Social media complaints surged after the campaign was flagged on LinkedIn and X in late 2024.
Users reported losing ₹50,000–₹2 lakh after initial “wins,” with withdrawal requests blocked unless additional deposits were made.
Despite reports to CERT-In and Google’s Web Risk team, takedowns lag due to the scale of spoofed domains.
Each spam page requires manual review to avoid accidental removal of legitimate content.
The campaign mirrors a 2024 Malaysian incident where government sites were backlinked to casino platforms, underscoring cross-border risks.
Cybersecurity experts urge organizations to:
- Audit website code for unauthorized scripts.
- Monitor search rankings for keyword anomalies.
- Implement strict file-upload controls on CMS platforms.
Google has delisted 2,300 malicious pages since January 2025, but ephemeral domains and encrypted traffic pose ongoing hurdles.
With losses exceeding ₹200 crore annually, this campaign highlights the critical need for proactive defense mechanisms in India’s digital governance infrastructure.
