Database management system is valuable element of any application, which works with big amount of information. It helps developers to store, search thru and edit data. 

A database is an organized block of data. It consists of schemas, tables, queries, reports, views, and other objects. As a rule, the data are organized to model aspects of reality in a way that supports processes requiring information, such as modeling the availability of plane seats in a way that supports finding an available plane.

A database management system (DBMS) is an application that interacts with the user, other applications, and the database itself to capture and analyze data.

A general-purpose DBMS is designed to allow the definition, creation, querying, update, and administration of databases.

There are many DBMSs available at the market now. In regularly updated Github ranking there are 30 systems and they all depend on their architecture, purpose, functionality and price. Let’s take a closer look at this list and find out, which of them are popular, which gain popularity fast and why.

Hackers made $226K in Monero breaking into Oracle WebLogic

The attacks started in December of 2017 as a group hackers installed Monero miners on Oracle WebLogic Servers, which led to hackers' profit of a quarter million dollars
12 January 2018   1292

Oracle WebLogic Server is a Java EE application server currently developed by Oracle Corporation. The experts at the SANS Technology Institute and Morphus Labs reported that a group of hackers was attacking Oracle weblogic Servers from December 2017, using the exploit code for the CVE-2017-10271 vulnerability in Oracle WebLogic servers, patched by Oracle in October 2017 and leaked to the web.

The hackers reportedly chose that vulnerability as it was not difficult to use it through Internet to put the malicious code on the Weblogic server, and the exploit included IP scanner that searched for vulnerable hosts, which eventually let hackers make $226.000 worth 611 Monero coins installing a cryptocurrency miner.

The attackers had access to all the information in PeopleSoft that is touching WebLogic servers, but rather than sell this information on the black market, which takes more work than writing a simple script to exploit the system and drop crypto mining software on it, they probably thought they could get more money by crypto mining.

Johannes Ullrich

Dean of research, SANS Technology Institute

Despite the fact that hackers were able to steal significant corporate data or install ransomware, they only installed a cryptocurrency miner to mine Monero hoping that high CPU use of the server stayes unnoticed.

At the moment of press, these are main market parameters of Monero:

  • Average price: $370,66
  • Marketcap: $5 779 654 391
  • 24h volume: $150 136 000
