Threat Actors Exploit Poorly Secured MS SQL Servers to Deliver Ransomware
In the rapidly evolving sphere of cybersecurity, threat actors are always on the lookout for vulnerabilities to exploit. A recent case in point is the exploitation of poorly secured Microsoft SQL (MS SQL) servers to deliver Cobalt Strike and a ransomware strain known as FreeWorld. Cybersecurity firm, Securonix, has given this attack campaign the name DB#JAMMER.
Distinctive Features of DB#JAMMER
What makes DB#JAMMER stand out from the myriad of threat campaigns is its unique employment of the toolset and infrastructure. The threat actors utilize various tools in their malicious endeavors. Some of these tools include enumeration software, Remote Access Trojan (RAT) payloads, exploitation tools and credential stealing software.
| Tool | Description |
|---|---|
| Enumeration Software | Used to identify vulnerabilities in the target system. |
| RAT Payloads | Allows threat actors remote access and control over the infected system. |
| Exploitation Tools | Used to exploit identified vulnerabilities. |
| Credential Stealing Software | Used to steal user credentials for unauthorized access. |
These tools, when employed in a coordinated manner, can wreak havoc on the targeted MS SQL servers. The end goal is to deliver Cobalt Strike and the FreeWorld ransomware, thereby compromising the critical national infrastructure of the target.
Implications and Preventions
The successful exploitation of MS SQL servers can have far-reaching implications. Not only does it pose a risk to the large organisations using these servers, but it also threatens to disrupt public-sector services and harm individuals and families.
- Secure your MS SQL servers: Ensure that your MS SQL servers are adequately secured against threats.
- Regular ISO 27001 audits: Conduct regular ISO 27001 audits to assess the effectiveness of your security infrastructure.
- Ransomware Readiness Assessment: Carry out regular ransomware readiness assessments to evaluate your preparedness against ransomware attacks.
While it’s crucial for large organizations to take the necessary precautions, it’s equally important for small-medium organisations and self-employed individuals to secure their systems.
