Threat Actors Targeting Microsoft SQL Servers to Deploy FreeWorld Ransomware

Threat Actors Targeting Microsoft SQL Servers to Deploy FreeWorld Ransomware

Sep 01, 2023 Database Security / Ransomware
Threat actors are exploiting poorly secured Microsoft SQL (MS SQL) servers to deliver Cobalt Strike and a ransomware strain called FreeWorld. Cybersecurity firm Securonix, which has dubbed the campaign DB#JAMMER , said it stands out for the way the toolset and infrastructure is employed. "Some of these tools include enumeration software, RAT payloads, exploitation and credential stealing software, and finally ransomware payloads," security researchers Den Iuzvyk, Tim Peck, and Oleg Kolesnikov said in a technical breakdown of the activity. "The ransomware payload of choice appears to be a newer variant of Mimic ransomware called FreeWorld." Initial access to the victim host is achieved by brute-forcing the MS SQL server, using it to enumerate the database and leveraging the xp_cmdshell configuration option to run shell commands and conduct reconnaissance. The next stage entails taking steps to impair system firewall and establish persistence by connecting to a remote SMB share...
Stealthy Microsoft SQL Server Backdoor Malware Spotted in the Wild

Stealthy Microsoft SQL Server Backdoor Malware Spotted in the Wild

Oct 22, 2019
Cybersecurity researchers claim to have discovered a previously undocumented backdoor specifically designed for Microsoft SQL servers that could allow a remote attacker to control an already compromised system stealthily. Dubbed Skip-2.0 , the backdoor malware is a post-exploitation tool that runs in the memory and lets remote attackers connect to any account on the server running MSSQL version 11 and version 12 by using a "magic password." What's more? The malware manages to remain undetected on the victim's MSSQL Server by disabling the compromised machine's logging functions, event publishing, and audit mechanisms every time the "magic password" is used. With these capabilities, an attacker can stealthily copy, modify, or delete the content stored in a database, the impact of which varies from application to application integrated with targeted servers. "This could be used, for example, to manipulate in-game currencies for financial gai...

Want to Grow Vulnerability Management into Exposure Management? Start Here!

Dec 05, 2024Attack Surface / Exposure Management
Vulnerability Management (VM) has long been a cornerstone of organizational cybersecurity. Nearly as old as the discipline of cybersecurity itself, it aims to help organizations identify and address potential security issues before they become serious problems. Yet, in recent years, the limitations of this approach have become increasingly evident.  At its core, Vulnerability Management processes remain essential for identifying and addressing weaknesses. But as time marches on and attack avenues evolve, this approach is beginning to show its age. In a recent report, How to Grow Vulnerability Management into Exposure Management (Gartner, How to Grow Vulnerability Management Into Exposure Management, 8 November 2024, Mitchell Schneider Et Al.), we believe Gartner® addresses this point precisely and demonstrates how organizations can – and must – shift from a vulnerability-centric strategy to a broader Exposure Management (EM) framework. We feel it's more than a worthwhile read an...
