cybernews: “Thomson Reuters, a multinational media conglomerate, left an open database with sensitive customer and corporate data, including third-party server passwords in plaintext format. Attackers could use the details for a supply-chain attack. The Cybernews research team found that Thomson Reuters left at least three of its databases accessible for anyone to look at. One of the open instances, the 3TB public-facing ElasticSearch database, contains a trove of sensitive, up-to-date information from across the company’s platforms. The company recognized the issue and fixed it immediately. Thomson Reuters provides customers with products such as the business-to-business media tool Reuters Connect, legal research service and database Westlaw, the tax automation system ONESOURCE, online research suite of editorial and source materials Checkpoint, and other tools. The size of the open database the team discovered corresponds with the company using ElasticSearch, a data storage favored by enterprises dealing with extensive, constantly updated volumes of data.
