===Massive data breach (''2020'')===

In September 2020, the Nitro PDF service suffered a massive data breach which exposed over 70 million unique e-mail addresses. Cyber-security 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.<ref name=":0" />

====Nitro's response====

On 21 October 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.<ref>{{Cite web |author= |title=Nitro |url=https://haveibeenpwned.com/breach/Nitro |website=Have I Been Pwned |date=2020 |access-date=4 Mar 2026 |url-status=live |archive-url=http://web.archive.org/web/20260222162541/https://haveibeenpwned.com/Breach/Nitro |archive-date=22 Feb 2026}}</ref>

In June 2025, customers that had bought a perpetual license for Version 12 and older suddenly found themselves receiving an error message informing them their license was expired. Attempts to use their serial numbers to activate would return an error stating that the number did not exist. When this was brought up on Nitro's support forum, an employee shared the following in response on 13 June 2025:<ref>{{Cite web |last=Capiral |first=Joseph |title=Nitro Pro is no longer supported + Serial Number not found for activation |url=https://community.gonitro.com/topic/22064-nitro-pro-is-no-longer-supported-serial-number-not-found-for-activation/ |website=Nitro |date=13 Jun 2025 |access-date=4 Mar 2026 |url-status=live |archive-url=http://web.archive.org/web/20251004224255/https://community.gonitro.com/topic/22064-nitro-pro-is-no-longer-supported-serial-number-not-found-for-activation/ |archive-date=4 Oct 2025}}</ref>
