**Hackers Exploit Qlik Sense Servers with Reverse Shells, Stage ActiveMQ and Veeam Exploits**
A concerning wave of targeted attacks has been observed against Qlik Sense servers, allowing hackers to establish a foothold on vulnerable systems. The attackers are using reverse shells to gain access to these servers, which are then leveraged as a springboard for further exploitation. Specifically, they are staging exploits for ActiveMQ and Veeam software, creating active attack paths that can lead to severe breaches.
Qlik Sense is a business intelligence platform used by numerous organizations worldwide to analyze data from various sources. These attacks likely exploit vulnerabilities in the server-side configuration of Qlik Sense deployments, allowing hackers to inject malicious code and create reverse shells. A reverse shell is a type of backdoor that allows an attacker to maintain access to a compromised system remotely.
The attackers are then using these established reverse shells as a conduit for further exploitation, particularly targeting ActiveMQ and Veeam software vulnerabilities. ActiveMQ is a popular open-source messaging server used in many enterprise environments, while Veeam is a leading provider of data protection solutions. Exploiting vulnerabilities in these systems can grant hackers elevated privileges, allowing them to move laterally within the network and access sensitive data.
The use of cross-domain privilege escalation by the attackers is also noteworthy. By mapping out privilege escalation routes across domains, they can identify key choke points where breaches are more likely to occur. This approach allows them to create a more robust attack path, making it increasingly challenging for defenders to detect and respond to these threats.
While the full scope of this campaign remains unclear, it’s evident that Qlik Sense servers have become an attractive target for hackers due to their widespread adoption and potential for exploitation. The use of reverse shells, ActiveMQ, and Veeam exploits demonstrates a sophisticated attack chain designed to evade detection and maximize impact.
**What You Can Do**
To mitigate the risk of these attacks, it’s essential for Qlik Sense administrators to review their server-side configurations and ensure they are up-to-date with the latest security patches. Regular vulnerability scanning and monitoring should also be implemented to detect potential weaknesses before they can be exploited. Additionally, organizations should consider implementing robust logging and alerting mechanisms to quickly identify and respond to suspicious activity on their networks. By taking proactive steps to secure Qlik Sense servers, defenders can reduce the likelihood of these attacks succeeding and minimize the associated risks.
