APT41, a sophisticated threat actor, has been observed maintaining a persistent presence on gambling company networks for nine months. This group utilizes custom tools and techniques, including phantom DLL hijacking and WMIC JavaScript loading, to achieve their objectives. These tactics have been particularly effective in evading detection and establishing long-term access. The group’s continued focus on the gambling industry underscores the sector’s vulnerability to advanced cyber threats, demanding enhanced security measures and vigilance to counter these sophisticated attacks.
