Ubuntu Forums Database Hacked

Canonical probe reveals user account details of 2 million stolen, passwords safe.

Ubuntu Forums’ database was recently discovered hacked after Canonical, the company behind Ubuntu, was alerted that someone claimed to have a copy of the Forums database. An investigation revealed that a security breach had exposed usernames, email, and IP addresses for 2 million users. Passwords, however, were not accessed. 

Canonical explained in a blog: "No active passwords were accessed; the passwords stored in this table were random strings as the Ubuntu Forums rely on Ubuntu Single Sign On for logins. The attacker did download these random strings (which were hashed and salted)."

The company further explained that the breach was due to a SQL injection vulnerability in the platform which powers the forum and which had not been patched.

“The attacker had the ability to inject certain formatted SQL to the Forums database on the Forums database servers…. This gave them the ability to read from any table, but we believe they only ever read from the ‘user’ table,” says Canonical.

The website was shut down as a precautionary measure and the server wiped clean and rebuilt.

database security
A DBMS typically includes a database security and authorization subsystem that is responsible for ensuring the security portions of a database against unauthorized access.The security mechanism of a DBMS must include provisions for restricting access to the database as a whole.

Re: Correct- but what about the authrized entities such as DBA.
Database Forensic (DBF) is a field of digital forensic investigation which deals with database contents and their metadata. It is considered as a significant field by which to identify, detect, acquire, analyse, and reconstruct database incidents and reveal an intruder's activities.  DBF has suffered from several issues which have resulted in it becoming a heterogeneous, confusing and unstructured domain. Examples of these issues include:  a variety of database systems infrastructure; the multidimensional nature of database systems; and domain knowledge effectively being scattered in all directions.  A variety of database systems infrastructures with multidimensional nature have enabled the DBF domain to be able to deal with specific incidents. Therefore, each database management system (DBMS) has a specific forensic investigation model/approach. Consequently, the issues of different concepts and terminologies in terms of forensic investigation process, as well as the scattering of domain knowledge in all directions have produced other challenges for DBF investigators and practitioners. This knowledge (such as models, processes, techniques, tools, frameworks, methods, activities, approaches, and algorithms) is neither organized nor structured, Further, it is universally dispersed such as in: the internet;  books, journals, conferences, online databases, book chapters, dissertations, reports, and organizations. Consequently, there is a lack of generic/standardized models by which to unify concepts and terminologies which may be used to reduce confusion and assist in organizing and structuring domain knowledge. This study discusses the DBF domain from several perspectives in order to highlight, extract, compare, merge and derive common concepts of domain, as well as to harmonize and reconcile concepts and definitions such as:  i) Database dimensions perspective; ii) Database ForensicTechnology perspective; and  iii) Database Forensic Investigation process perspective.
