Cycldek, a China-based threat actor, may be more dangerous than previously thought, Kaspersky says. The group has been using a variety of new tools, tactics, and procedures in attacks against government agencies in Vietnam, Laos, and Thailand. Among the new tools is one called USBCulprit, which appears designed for use in air-gapped environments where systems are not directly accessible from an external network. The malware has no capability of communicating over the network and can only pass any information it has stolen to physical media.”]
