Nitro Pro is a Portable Document Format (PDF) editing application[1] and electronic signature software.[2]
Background[edit | edit source]
Claimed to be used by over 10 thousand business customers and 1.8 million licensed users, Nitro is an application used to create, edit, and sign PDFs and digital documents. As part of their service offering, Nitro offers a cloud service used by customers to share documents with coworkers or other organizations involved in the document creation process. A massive data breach suffered by the Nitro PDF service impacts many well-known organizations, including Google, Apple, Microsoft, Chase, and Citibank.[3]
Incident[edit | edit source]
In September 2020, the Nitro PDF service suffered a massive data breach which exposed over 70 million unique email addresses. Cybersecurity intelligence firm Cyble has told BleepingComputer that a threat actor is selling the user and document databases, as well as 1TB of documents, that they claim to have stolen from Nitro Software's cloud service. Cyble states that the 'user_credential' database table contains 70 million user records containing email addresses, full names, bcrypt hashed passwords, titles, company names, IP addresses, and other system-related data.[3]
Nitro's response[edit | edit source]
On October 21st 2020, Nitro Software issued an advisory to the Australia Stock Exchange, stating that they were affected by a "low impact security incident" but that no customer data was impacted. Despite Nitro's advisory, the data breach exposed names, bcrypt password hashes and the titles of converted documents. The data was provided to HIBP by dehashed.com.[4]
As of April 2023 Nitro Pro (NTO) has been delisted from the Australian Stock Exchange[5] when the company was purchased by Ellerston Capital.[6]
