Qlik Sense flaws exploited in Cactus ransomware campaign
2023-12-01 12:08

Attackers are exploiting three critical vulnerabilities in internet-facing Qlik Sense instances to deliver Cactus ransomware to target organizations, Arctic Wolf researchers have warned.

Qlik Sense is a business intelligence and data analytics solution popular with governmental organizations and enterprises.

Attackers wielding Cactus ransomware have previously been seen breaching large commercial organizations by exploiting vulnerabilities in VPN appliances.

"Based on patch level Qlik Sense is likely being exploited either via the combination or direct abuse of CVE-2023-41266, CVE-2023-41265 or potentially CVE-2023-48365 to achieve code execution," Arctic Wolf Labs researchers shared.

"The Qlik Sense vulns were discovered in August and September by Praetorian, an InfoSec vendor - unfortunately they published a full exploit chain, which the ransomware group has lifted wholesale," security researcher Kevin Beaumont noted.

Beaumont says that he has seen another ransomware group exploiting Qlik Sense.
