Cisco Talos uncovered 'DKnife', a sophisticated gateway-monitoring and adversary-in-the-middle (AitM) framework comprising seven Linux-based implants. Used since 2019, DKnife performs deep-packet inspection, traffic manipulation, and malware delivery via routers and edge devices. It targets various devices, including PCs, mobile devices, and IoT, delivering ShadowPad and DarkNimbus backdoors. The framework primarily targets Chinese-speaking users, with evidence suggesting China-nexus threat actors as operators. DKnife's capabilities include DNS hijacking, Android application update hijacking, Windows binary hijacking, anti-virus traffic disruption, and user activity monitoring. A link to the WizardNet campaign was also discovered, indicating a shared development or operational lineage.
TheWizards, a China-aligned threat actor, employs Spellbinder, a lateral movement tool that enables adversary-in-the-middle attacks through IPv6 SLAAC spoofing. This technique allows the group to intercept network traffic and redirect legitimate Chinese software updates to malicious servers. The attackers deploy their custom backdoor, WizardNet, which can load additional modules and gather system information. TheWizards targets individuals, gambling companies, and other entities in several Asian countries and the UAE. The group is linked to Sichuan Dianke Network Security Technology Co., Ltd. (UPSEC), known for supplying malware to other threat actors. TheWizards' sophisticated toolset and tactics demonstrate their advanced capabilities in compromising networks and evading detection.
TheWizards, a China-aligned APT group, employs Spellbinder, a lateral movement tool for adversary-in-the-middle attacks through IPv6 SLAAC spoofing. This technique allows them to intercept network traffic and redirect legitimate Chinese software updates to malicious servers. The group targets individuals, gambling companies, and entities in Southeast Asia, UAE, China, and Hong Kong. Their malware chain includes the WizardNet backdoor and utilizes DNS hijacking to deliver malicious updates. Evidence links TheWizards to Sichuan Dianke Network Security Technology Co., Ltd. (UPSEC), suggesting it may be a digital quartermaster for this APT group. The attackers use sophisticated tools and techniques to evade detection and maintain persistence on compromised systems.
