Veilige AI-privacyextensies in 2026

In januari 2026 werden twee kwaadaardige Chrome-extensies met 900.000+ gebruikers betrapt op het exfiltreren van ChatGPT- en DeepSeek-gesprekken elke 30 minuten. Hoe u veilige extensies identificeert.

Het Incident van Januari 2026

Bijgewerkt voor 2026. In januari 2026 ontdekten beveiligingsonderzoekers twee kwaadaardige Chrome-extensies met 900.000+ gebruikers.

De namen waren gekozen om op echte AI-tools te lijken:

  • "Chat GPT for Chrome with GPT-5, Claude Sonnet & DeepSeek AI" — 600.000+ gebruikers
  • "AI Sidebar with Deepseek, ChatGPT, Claude and more" — 300.000+ gebruikers

Beide deden hetzelfde. Ze stuurden volledige ChatGPT- en DeepSeek-gesprekken naar een externe server elke 30 minuten.

De gestolen gegevens omvatten broncode, persoonlijke details, juridische besprekingen, bedrijfsplannen en financiële records.

Hoe de Extensies Vertrouwenssignalen Omzeilden

De tools vroegen om "anonieme, niet-identificeerbare analytische gegevens" te verzamelen. Die formulering klinkt veilig. Ze verschenen in de Chrome Web Store met:

  • Nep-beoordelingen en kunstmatig hoge cijfers
  • Beschrijvingen die echte AI-merknames vermelden
  • Iconen die op officiële AI-producten lijken

Standaard Chrome Web Store-screening detecteerde de kwaadaardige functionaliteit niet vóór wijdverbreide installatie.

De Architecturele Oplossing

Het fundamentele probleem: browser-extensies met brede machtigingen kunnen alles lezen wat de browser toont. De oplossing is niet het vertrouwen op extensie-reputatie. Het is het garanderen dat gevoelige gegevens nooit in onbeschermde vorm de browser bereiken.

Extensies die PII anonimiseren vóór weergave of verzending lossen dit architectureel op. Zelfs als een kwaadaardige extensie de gegevens onderschept, onderschept ze anonieme tokens — niet de werkelijke klantgegevens.

Who built this

A small team of engineers and lawyers built this.

We ship from Europe and work in the open.

Our founder note spells out why we started.

Where to start

How the parts fit

A browser add-on cleans text inside Chrome.

A Word plug-in handles drafts in Office.

A small desktop tool works on whole folders.

An agent protocol link feeds large models safely.

All four share one core engine and one rule set.

Words from our team

We started this work after a lunch about cookies.

One friend kept getting odd ads on her phone.

We asked why a court file leaked through a draft.

We sketched the first build on a napkin that week.

By month three we had a tiny demo for a friend.

She used it on her first case the next day.

Common questions we hear

Can the tool read scanned PDFs? Yes, with OCR.

Does it work on long files? Yes, in small chunks.

Can I roll my own rule set? Yes, save it as a preset.

Does it run offline? The desktop build runs offline.

Do you keep my files? No, the cloud build wipes after each run.

Will it learn from my work? No, we never train on inputs.

A short tour of the workflow

Upload a file or paste a snippet of prose.

Pick the entities you want gone from the draft.

Choose a method: replace, mask, hash, encrypt, or redact.

Press run and watch the side panel show each hit.

Skim the result and tweak any rule that misfired.

Save the cleaned file or send it to a teammate.
