Analysis Summary
PowerBrace is a PowerShell remote access tool (RAT) or backdoor having the functionality to run commands, manipulate files, upload/download files from a C2 server, manipulate running processes, collect system information and manipulate the Windows registry. It communicates over TLS with a custom protocol using XOR encoding. Minor obfuscation occurs throughout the script, which makes it slightly more difficult to analyse. The script uses several light forms of obfuscation. Function names and variable names are replaced with non-descriptive names, and strings are stored as base64 encoded Unicode. The PowerBrace malware was also observed in attacks on financial institutions in Q1 2020.
This malware collects various operating system information and sends it to the C2 server. The collected data includes:
• Internal IP address
• Computer name
• Username
• OS version
• OS architecture
• Proxy status
• Proxy server
• Script path
• Last boot time
• OS caption
• OS language
• OS country code
• Primary C2 address and port
• Secondary C2 address and port
• 32/64 bit system
