Bottom line: A China-aligned group distributes targeted phishing emails with malicious ZIP attachments in Czechia and Taiwan to gain access to government, research institutions, and financial sector organizations.
A cyber-espionage campaign named Operation Dragon Weave targets government and citizens in Czechia and Taiwan with the goal of deploying an AdaptixC2 agent. This represents an escalated threat to critical sectors.
Seqrite Labs has documented a campaign called Operation Dragon Weave that is specifically targeting actors in the Czech Republic and Taiwan. The attackers leverage spear-phishing emails as an attack vector while distributing ZIP files containing the AdaptixC2 agent – a remote-access malware for remote access and command execution.
According to Seqrite Labs findings, affected organizations are in Government, Research, Academic, Technology, and Financial Services sectors. The selection of these industries suggests interest in sensitive data, intellectual property, and financial information.
For CISOs, this translates into concrete action requirements: employees in these sectors require immediate training on spear-phishing tactics, email filtering must exert stronger control over ZIP attachments or suspicious archives, and network segmentation should ensure that a single compromised system cannot immediately access critical assets. Under the NIS2 Directive compliance regime as well, such targeted campaigns gain in significance since they target system integrity.
