The internet wasn’t designed to be a hostile place, but the sheer speed at which local scams propagate in Chile forced me to react. Fraudulent SMS messages simulating unpaid highway toll (TAG) bills, fake CorreosChile notifications claiming small customs fees to release non-existent packages, or near-identical clones of banking portals saturate the devices of thousands of people every day.
I knew we had to go a step further than reactive reporting. For months, I have seen first-hand how, when reporting these phishing campaigns directly to Cloudflare or the hosting companies that support the fraudulent infrastructure, the process becomes slow and useless in the short term: it can take hours or even days, and many times these platforms simply do nothing due to business convenience or bureaucracy, allowing the scam to remain active and claiming new victims.
Instead of continuing to hunt down scammers and begging providers to take down the sites one by one, I decided to build a direct shield.
Today, I am pleased to announce the official launch of Huaso Shield, the browser extension I developed under my company, Kometa Networks, designed specifically to block active phishing and smishing scams in Chile in real-time. You can access its official website at huasoshield.kometa.cl.
What is Huaso Shield, and how does it work?
Huaso Shield acts as a local traffic inspector in your browser. When you click a link received via text message (SMS), email, or social media, the extension instantly checks the domain against a database of threats tailored to the Chilean context.
If the domain is flagged as malicious, the extension halts the connection and renders a clear warning screen, preventing you from entering personal details, bank credentials, or credit card numbers.
Three Non-Negotiable Engineering Pillars
When designing the extension, I established three technical guidelines to ensure trust and performance:
1. Absolute Privacy (Zero-Tracking)
To me, privacy is not a configuration toggle; it is the foundation of the tool. The extension does not analyze or record your browsing history in the cloud. All blocking and filtering logic happens locally on your computer. We do not collect personal information, require logins, or send telemetry to external servers.
2. Smart Synchronization
To avoid slowing down your browsing experience or consuming system resources by querying external servers for every new tab you open, the extension’s background Service Worker runs silently every 60 minutes via native Chrome alarms. During this interval, it performs a lightweight download of the consolidated list of new threats from our official subdomain huasoshield.kometa.cl.
3. Agile Moderation and Reporting
The Huaso Shield database is constantly updated thanks to community reports and the automation I programmed to validate and consolidate new threats within minutes, ensuring a collective protection shield that is always up to date.
Behind the Scenes: The Fight Against Local Phishing
Traditional phishing campaigns are often caught by global blocklists like Google Safe Browsing. However, Chilean threat actors have learned to register local domains (.cl, .com, .info) that remain active for only 3 to 4 hours. In that narrow window of time, they manage to defraud dozens of people before global security entities flag them and while hosting companies ignore reports.
Huaso Shield solves this latency issue via a backend that aggregates rapid user reports and automates synchronization with official incident response teams in Chile, such as public alerts published by the Chilean Government’s CSIRT.
Join Us and Protect Your Circle
Cybersecurity is not just a software problem; it’s a community effort. Huaso Shield is and will always be 100% free and ad-free.
- Install the extension: It is officially available now on the Chrome Web Store.
- Report threats: If you receive a suspicious SMS or email, report it via the extension’s popup menu so we can verify it and add it to the community shield.
Let’s make the internet a slightly safer place, one shield at a time. 🛡️
