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.
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.
The naming of ElasticSearch indices inside the Thomson Reuters server suggests that the open instance was used as a logging server to collect vast amounts of data gathered through user-client interaction. In other words, the company collected and exposed thousands of gigabytes of data that Cybernews researchers believe would be worth millions of dollars on underground criminal forums because of the potential access it could give to other systems.
Meanwhile, Thomson Reuters claims that out of three misconfigured servers the team informed the company about, two were designed to be publicly accessible. The third server was a non-production server meant for “application logs from the pre-production/implementation environment.”
