Sept 1 (Reuters) - 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.

Here are a few details:

• 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.

• Hackers accessed files in fewer than a third of the compromised ⁠accounts, the company said.

• Shares of Dropbox ​fell around 2.4% ‌in extended trading on Tuesday.

• Dropbox told Reuters that ⁠it 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.

• Dropbox said it had reported the incident to data protection regulators.

• Lenovo identified a "legacy ​integration" between Lenovo ID and Dropbox ⁠that "could be used to improperly authenticate certain Dropbox accounts". The ​company said its own customers ‌were not affected and that an ​investigation was ongoing.
