These techniques were essential in uncovering the multi-stage delivery mechanisms of RONINGLOADER.
Special attention was given to the loader’s evasion tactics, including the abuse of Protected Process Light (PPL) privileges, the deployment of signed drivers, and the manipulation of Windows Defender Application Control (WDAC) policies. By reverse-engineering these components, researchers gained insights into how the malware circumvents popular security solutions. Such detailed analysis forms the backbone of understanding adversary behavior.
The investigation also involved tracking the behavior of embedded binaries within the installers, revealing how benign and malicious elements coexist to deceive users and systems alike. This dual-layered approach to installation underscores the complexity of the attack chain, necessitating advanced tools and expertise to fully unravel its operations.
Findings from the Campaign Analysis
The analysis uncovered a meticulously crafted attack sequence initiated by trojanized installers that launch both legitimate and malicious NSIS binaries. The malicious component triggers shellcode injection, ultimately deploying a modified Gh0st RAT capable of keylogging, clipboard data theft, and executing remote commands. This trojan’s versatility makes it a significant threat to compromised systems.
Further examination revealed RONINGLOADER’s aggressive tactics to disable security tools such as Microsoft Defender, Qihoo 360 Total Security, and others by terminating processes, manipulating firewall settings, and using signed drivers for stealthy operations. These measures ensure the malware operates undetected, highlighting a direct challenge to endpoint protection mechanisms widely used in the target regions.
Additional campaigns, dubbed Campaign Trio and Campaign Chorus, were identified, showcasing large-scale brand impersonation affecting thousands of domains and over 40 applications like QQ Music and Sogou browser. These efforts demonstrate an evolution from simple droppers to intricate infection chains, leveraging public cloud services and redirection domains to evade network filters, thus broadening the attack surface.
