![]() The direct fix is fast, it can quickly fix corruptions directly in the database file. ![]() IBSurgeon FirstAID can recover databases with a direct fix or wth data extraction. Exporting data from the encrypted Firebird database The same approach is used to recover databases from corrupted HDDs. In this case, such encrypted database can be considered as a heavily corrupted database file, and IBSurgeon FirstAID is the tool which can perform the export of the data from the encrypted Firebird database file. For example, in 10Gb database there was encrypted less than 1% of data, and other 99% were fine. Since all pages have strong relationships, even few recent of encrypted pages make the whole database unreadable by Firebird engine. Usually, such ransomware encrypts not the whole database file, but the small part of it – header page and some % of database pages inside the database. Database pages in Firebird database contain different type information: metadata, user's data, indices, generators, etc. The 2 companies were hit with ransomware which has partially encrypted their Firebird databases.Īs you know, Firebird database file is a set of pages of the same size. There are different types of ransomware, let's consider their impact on the Firebird databases. Of course, it is necessary to have reliable (and suitable for servers) antivirus, but can we do specifically to protect Firebird database? In general, ransomware is not designed to encrypt specifically Firebird databases it just encrypts all files on the computer, and then asks for the ransom to provide the password for decrypting it, and even if you pay, you may not get any decryption password or response at all (also, it is necessary to check antivirus websites: they often publish pin-codes or even decryption tools for that ransomware. In this article, we will consider how these problems were solved. Luckily we were able to help all of them, but the scale of the problem definitely increases. Ransomware attacks became the serious problem for many companies: during the last week, we had 3 incidents from different customers which had their Firebird databases encrypted by ransomware viruses. How to protect Firebird databases from ransomware?
