DashboardFox - Alternative to Qlik Sense

In the world of data analytics, it's crucial to have secure and reliable software to process and visualize valuable data.

Unfortunately, there's a new ransomware threat called Cactus ransomware that's been causing trouble for users of Qlik Sense, a popular data analytics solution.

We want to inform you about this issue without being biased or petty, as our goal is to prioritize the safety of our customers. Here's what you need to know:

  • Cactus ransomware has been actively targeting unpatched instances of Qlik Sense, taking advantage of two critical vulnerabilities: CVE-2023-41266 and CVE-2023-41265. These vulnerabilities allow unauthorized access, privilege escalation, and the execution of malicious code on backend servers.
  • The attackers use sneaky tactics to infiltrate systems. They exploit the Qlik Sense Scheduler service, download tools using PowerShell and BITS, and disguise executables as Qlik files or fetch legitimate tools like AnyDesk from official sources. They also use methods like changing passwords and setting up RDP tunnels to remain undetected while gathering information and moving through the network.
  • Once they've gained control, the hackers deploy the Cactus ransomware, encrypting valuable data and demanding a ransom from the victims. This double-extortion tactic puts businesses at risk not only of losing their data but also their financial stability.

How to Protect from Qlik Sense Cactus Ransomware

To protect yourself from this ransomware campaign, it's crucial to promptly upgrade your Qlik Sense software. Qlik has released security updates to address these vulnerabilities. Here are the recommended versions to ensure your system is secure:

  • August 2023 Patch 2
  • May 2023 Patch 6
  • February 2023 Patch 10
  • November 2022 Patch 12
  • August 2022 Patch 14
  • May 2022 Patch 16
  • February 2022 Patch 15
  • November 2021 Patch 17

By applying these patches, you can safeguard your system against known vulnerabilities and minimize the risk of falling victim to the Cactus ransomware campaign.
