The Telegraph newspaper managed to leak 10TB of subscriber data and server logs after leaving an Elasticsearch cluster unsecured for most of September, according to the researcher who found it online.

After sampling the database to determine its owner, Diachenko saw the personal details of at least 1,200 Telegraph subscribers along with a substantial quantity of internal server logs, he told The Register.

Aside from potential scam emails, the risk from this breach is relatively low unless having your news-reading habits collated in one place might cause professional embarrassment: Diachenko highlighted that in the data sample he viewed were a handful of gov.

Unsecured Elasticsearch clusters are relatively common ways for personal or sensitive data to be exposed to the wider world.

Microsoft managed to do something similar with 6.5TB of Bing search data a year ago.

Diachenko himself - an expert in finding unsecured databases online - spotted 106 million travellers' details freely accessible online through a data store in Thailand.
