Threats Tagged 'software update hijacking'

China-aligned threat actor PlushDaemon has been conducting espionage operations since 2018, targeting entities in China, Taiwan, Hong Kong, Cambodia, South Korea, the United States, and New Zealand. The group employs a custom backdoor called SlowStepper and uses a network implant named EdgeStepper to hijack legitimate updates. EdgeStepper redirects DNS queries to a malicious node, rerouting traffic from legitimate infrastructure to attacker-controlled servers. The group has also exploited web server vulnerabilities and performed a supply-chain attack. PlushDaemon's adversary-in-the-middle technique involves compromising network devices, deploying EdgeStepper, and using it to redirect DNS queries for software updates to malicious nodes. This allows them to serve malicious updates containing the LittleDaemon downloader, which then deploys the SlowStepper implant.

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.
