A Chinese-speaking advanced persistent threat (APT) has been linked to a new campaign targeting gambling-related companies in South East Asia, particularly Taiwan, the Philippines, and Hong Kong.
Cybersecurity firm Avast dubbed the campaign Operation Dragon Castling, describing its malware arsenal as a “robust and modular toolset.” The ultimate motives of the threat actor are not immediately discernible as yet nor has it been linked to a known hacking group.
While multiple initial access avenues were employed during the course of the campaign, one of the attack vectors involved leveraging a previously unknown remote code execution flaw in the WPS Office suite (CVE-2022-24934) to backdoor its targets. The issue has since been addressed by Kingsoft Oﬃce, the developers of the office software.
