Investigation found Dropbox Sign account data may have been breached.
Attackers were able to breach production systems for the DropBox Sign eSignature platform, and gained access to authentication tokens, MFA keys, hashed passwords, and customer information.
In a statement, the company said they detected unauthorized access to DropBox Sign's production systems on April 24. An investigation found a threat actor had accessed Dropbox Sign customer information.
This included Dropbox Sign customer information such as emails, usernames, phone numbers and hashed passwords, in addition to general account settings and certain authentication information such as API keys, OAuth tokens, and multi-factor authentication.
“We believe that this incident was isolated to Dropbox Sign infrastructure, and did not impact any other Dropbox products,” it said. “We’ve been working around the clock to mitigate risk to our customers, and we’re in the process of reaching out to all users impacted by this incident who need to take action, with step-by-step instructions on how to further protect their data.”
