Security researcher Justin Paine said in a blog post that he found the database, containing DNS queries and Netflow data, on the internet without a password, this could be a major problem for high-risk individuals, like journalists and activists, whose internet records could be used to identify their sources.
DNS queries are a normal side-effect of using the internet. Every time you visit a website, the browser converts a web address into an IP address, which tells the browser where the web page lives on the internet. Although DNS queries don’t carry private messages, emails, or sensitive data like passwords, they can identify which websites you access and which apps you use.
Paine alerted AIS to the open database on May 13. But after not hearing back Paine reported to Thailand’s national computer emergency response team ThaiCERT, which contacted AIS about the open database, The database was inaccessible a short time later.
Thailand’s largest cell network AIS has pulled a database offline that was spilling billions of real-time internet records on millions of Thai internet users.
