The notice goes on to say that a third parties managed to gain gained access to data 'My Account' data. This includes information such as email addresses, passwords, names, phone numbers, company names and IP addresses.
The company has not said whether passwords were encrypted or stored in a readable format, and has remained strangely quiet about the incident on its social media channels.
Foxit Software stresses that no payment information was exposed, but the news will still be concerning for anyone who has paid for software from the company. While users of its free programs do not have to save personal information to My Account, anyone who has paid for software is required to do so. Foxit warns users to be vigilant for phishing scams.
An investigation is underway to determine what happened, and Foxit is working with law enforcement agencies and data protection authorities, as well as conducting analysis via a security management firm.
