Hackers Target Qlik Sense Servers With Reverse Shells, Stage ActiveMQ and Veeam Exploits

AI-summarised brief · reviewed before publication

Threat actors targeted Qlik Sense servers in October 2026, attempting to deliver PowerShell reverse shells to multiple EU customers within a three‑minute window. The activity mirrors a November 2023 CACTUS ransomware campaign that exploited the same Qlik vulnerabilities, now patched in August–September 2023. Cynet’s analysis revealed a one‑line reverse shell to 45.115.26.23:4455, followed by a Windows Go reverse shell to 45.115.26.23:4456 for reconnaissance and persistence. The malware also sought ActiveMQ processes, collected Linux credentials, and installed OpenSSH via scheduled tasks. An exposed directory on the same IP hosts a custom Go backdoor, ActiveMQ exploit, and a modified Veeam toolchain, suggesting preparation for broader attacks.

💡 Why It Matters

  • · The reuse of previously patched Qlik flaws shows attackers’ persistence and the risk of incomplete fixes.
  • · The discovery of a multi‑stage backdoor and exploitation of other enterprise tools signals a coordinated effort to expand lateral movement and persistence across diverse environments.
