Dropbox said on Tuesday that around 5,000 accounts were compromised last month, with hackers viewing and downloading content stored on the cloud-storage platform. Some Dropbox users received an email from the company on Monday notifying them that their accounts have been accessed without authorization between August 4 and August 21, Dropbox confirmed after Bloomberg News reported the hack earlier in the day. Dropbox identified unauthorized access affecting accounts linked to a Lenovo ID that did not have its two-factor authentication enabled, prompting the company to terminate all sessions authenticated through a Lenovo ID. The company has removed any links between Lenovo IDs and Dropbox accounts and changed its systems so that users must enter their Dropbox password before accessing an account through Lenovo. Is cloud storage too risky for any company ?
