Deep#Door: A Sophisticated Malware Framework

A recently discovered Python-based backdoor framework, known as Deep#Door, has been found to provide attackers with persistent remote command execution and surveillance capabilities on Windows computers.

Infection Chain and Persistence

According to security researchers, the malware’s infection chain begins with the execution of a batch script that disables the system’s security controls, including Windows SmartScreen, firewall logging, and antivirus software functionality.

According to security researchers, “The malware then loads an embedded Python payload and establishes multi-layered persistence through registry modifications, scheduled task creation, and placement of scripts in the startup folder.”

This approach allows the attacker to simplify delivery and evade network-based detection, as the payload is directly embedded within the batch script’s body.

Capabilities and Activities

Shell command execution
File manipulation
System and network reconnaissance
Surveillance operations such as keylogging, clipboard monitoring, and screenshot capture
Access to a computer’s microphone and webcam
Harvesting of credentials and SSH keys
Destructive operations like overwriting the master boot record or forcing system crashes

Researchers note that Deep#Door incorporates a highly aggressive set of defense evasion techniques designed to bypass security controls, evade detection, and complicate forensic analysis.

Communication and Command-and-Control Infrastructure

The malware dynamically constructs a range of possible communication ports to reach its command-and-control infrastructure, even if specific ports are blocked, and uses public tunneling for covert and resilient communication that blends with legitimate traffic.

Based on its capabilities, it is likely that Deep#Door was designed for espionage purposes.
