Dropbox Reports Approximately 5,000 Accounts Compromised in August Hack

Dropbox confirmed that approximately 5,000 accounts were compromised between August 4 and August 21. The breach occurred due to unauthorized access through a Lenovo ID without two-factor authentication enabled. Dropbox notified affected users via email on Monday after the incident was initially reported by Bloomberg News earlier in the day. Hackers accessed files stored on the cloud-storage platform, though only fewer than one-third of compromised accounts were impacted. In response, Dropbox terminated all sessions linked to a Lenovo ID and removed any integration between Lenovo IDs and Dropbox accounts. The company also updated its systems so users must enter their Dropbox password before accessing an account through a Lenovo ID. Dropbox reported the incident to data protection regulators. Shares fell around 2.4% in extended trading on Tuesday following the announcement.
