Stage 1: Dropper and Cryptominer
The preliminary utility acts as a dropper, decrypting and putting in subsequent malware phases.
It concurrently runs a cryptocurrency mining module that prompts when the system display screen locks, decreasing person suspicion. As soon as Stage 2 installs efficiently, the mining exercise terminates and management is transferred to the subsequent part.
Stage 2: Persistence and Backend Initialization
This stage establishes long-term persistence by registering a number of broadcast receivers, hiding the launcher icon, and sustaining steady background execution.
It initializes connectivity with Google Firebase backend infrastructure for sufferer information storage, distant configuration, and command-and-control communication.
Stage 2 additionally runs unbiased cryptomining operations, serving as each a management layer and monetization part.
