NikiTeaR
Intelligence Profile
NikiTeaR is a sophisticated, custom-developed RAT, which is a rewritten variant of the NikiHTTP (aka NikiTea) RAT.
It supports the following commands:
- srun <EXEC> <ARGS>: Executing arbitrary commands with elevated privileges.
- up/down <FILENAME>: Performing remote file operations (upload/download).
- screen: Capturing screenshots for reconnaissance.
- conn <IP_ADDRESS> <PORT>: Establishing a reverse shell
- memload <EXPORT>: Loading additional DLL into memory.
- die <COMMAND>: Terminates the process and remove trace
It is delivered via a multi-staged execution chain, beginning with a Golang-based dropper that executes a loader, a DLL with the internal name MemLoad_V3.dll, capable of loading DLL reflectively.
Its internal DLL name is httptroy_dll.dll.
To resist analysis, the backdoor is heavily obfuscated; it utilizes custom hashing to conceal Windows API calls, and employs a combined Base64+XOR encryption for C&C traffic and internal character strings, which are dynamically reconstructed at runtime.
Threat Analysis
NikiTeaR is a advanced-sophistication threat actor of undetermined national origin, engaged in cyber operations with a primary motivation of espionage.
The group's espionage-oriented operations suggest a state-sponsored or state-aligned mandate, typically focused on stealing intellectual property, government secrets, or military intelligence. Targets are usually selected for strategic value rather than financial gain.
Classified as an advanced threat actor, NikiTeaR likely develops or acquires zero-day exploits, employs custom malware toolchains, and demonstrates long-term persistence capabilities — hallmarks of a well-resourced operation consistent with nation-state backing.
