Security researchers have found dozens of companies inadvertently leaking sensitive corporate and customer data because staff are sharing public links to files in their Box enterprise storage accounts that can easily be discovered. The discoveries were made by Adversis, a cybersecurity firm, which found major tech companies and corporate giants had left data inadvertently exposed. Although data stored in Box enterprise accounts is private by default, users can share files and folders with anyone, making data publicly accessible with a single link. But Adversis said these secret links can be discovered by others. Using a script to scan for and enumerate Box accounts with lists of company names and wildcard searches, Adversis found more than 90 companies with publicly accessible folders.
