Networks breached after ransomware slips past Qlik Sense security flaws

Description:
Three separate flaws, patched last summer, are being abused by a group called 
Cactus.

FULL STORY
======================================================================

Hackers were observed exploiting multiple critical vulnerabilities in the 
Qlik Sense data analytics solution to deploy ransomware and steal sensitive 
company data. 

This is according to a new report from cybersecurity researchers Arctic Wolf, 
which claims that Cactus abused three flaws discovered, and patched, in late 
August and late September. 

As per the report, Qlik first found two flaws - CVE-2023-41265 and 
CVE-2023-41266, in late August this year. A month later, the company 
discovered that one of the patches did not work as intended, leading to a 
separate vulnerability tracked as CVE-2023-48365. All three flaws were 
subsequently addressed and patches were issued.

These three flaws allowed attackers to generate anonymous sessions and run 
HTTP requests to unauthorized endpoints, or elevate privileges and run HTTP 
requests on backend servers hosting the application. 

Cactus was using the flaws as a means of initial access to corporate networks 
with unpatched Qlik Sense instances. The group forced the Qlik Sense 
Scheduler service to initiate new processes, and then used PowerShell and the 
Background Intelligent Transfer Service (BITS) to download remote access 
software such as AnyDesk. 

It also used different infostealing software to grab sensitive corporate 
data, but at the end of the day, it was the Cactus encryptor that was the 
most disruptive. To protect against such attacks, Qlik recommended its users 
upgrade to the following versions of Sense Enterprise for Windows: 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 

Cactus is a relatively new entrant in the ransomware game, first being 
spotted in March this year. It has the usual modus operandi, stealing 
sensitive data and encrypting systems, to later demand payment in 
cryptocurrency in exchange for the decryption key and for keeping the data 
private.
