FortiGuard Labs is aware of a report that CVE-2022-30190 is exploited in the wild to deliver Qakbot malware. Currently, a patch is not available for CVE-2022-30190. Also known as Qbot and Pinkslipbot, Qakbot started off as a banking malware. In recent years, Qakbot was seen as a delivery vehicle for other malware, which often results in a compromised machine being infected with ransomware.Why is this Significant?This is significant because CVE-2022-30190 is a Windows vulnerability that has no available patch and is being abused in the field. The current attack campaign delivers Qakbot to victim’s machine. While final payload has not been identified nor reported, often Qakbot infection leads to ransomware deployed to the compromised machine. A publicly available report suggests Black Basta ransomware was deployed through Qakbot.What is CVE-2022-30190?CVE-20022-30190, also known as Follina, is a vulnerability in Microsoft Support Diagnostic Tool, which uccessful exploitation allows an attacker to run arbitrary code with the privileges of the calling application. FortiGuard Labs previously released Outbreal Alert and Threat Signal on CVE-2022-30190. See the Appendix for links to “MSDT Follina” and “Follina: 0-day Windows MSDT Vulnerability (CVE-2022-30190) Exploited In The Wild”.How does the Current Qakbot Campaign Work?Reportedly, malicious emails arrive with an HTML attachment. Opening the HTML attachment downloads and saves a .zip file that an inner IMG file inside. The IMG file contains a DLL, a Word document, and a .LNK file. The DLL is a Qakbot variant which the link file will execute. Alternatively, the Word file will download and execute a remote HTML file, which has a script to abuse CVE-2022-30190, which then download and execute a Qakbot variant.
