NineRAT Overview

NineRAT is a Remote Administration Trojan (RAT) crafted in the DLang programming language. This RAT is a tool utilized by a threat actor group identified as Lazarus. A RAT, short for Remote Administration Trojan, represents a category of malware that affords illicit remote access to a target computer. This unauthorized access empowers cyber adversaries to exercise control over the system, potentially pilfer sensitive data, and execute various malicious operations.

Technical Analysis

NineRAT leverages Telegram as its command-and-control (C2) channel. It serves as a conduit for receiving commands, communicating output, and facilitating file transfers between the compromised system and its operators. This choice by Lazarus reflects a strategic approach aimed at evading detection measures. By utilizing Telegram, a widely adopted and legitimate service for C2 communications, they can elude network and host-based security measures more effectively. NineRAT boasts a versatile set of command capabilities, enabling a wide range of operations on an infected system. It can collect initial system information, configure token values, set polling intervals, establish dormant periods, self-upgrade, terminate its execution, and uninstall itself from the compromised endpoint.

Additionally, NineRAT streamlines file transfers to the C2 server and employs a BAT file for self-uninstallation. Among its reconnaissance commands are functions for retrieving system details and querying the operating system architecture. NineRAT empowers cybercriminals to exfiltrate data, putting sensitive information in jeopardy. Its capabilities, such as manipulating communication intervals and dormancy periods, enable discreet and prolonged control, making detection more challenging. Furthermore, the self-upgrade feature underscores the ever-evolving nature of the threat landscape. The option for self-uninstallation not only aids in covering tracks but also exposes victims to the risk of recurrent or diverse malicious attacks.

Spreading Methods

The entity orchestrating NineRAT attacks has a track record of capitalizing on the Log4Shell vulnerability to propagate the malware. Moreover, the delivery of this malicious software frequently takes place through multiple avenues, including the utilization of pirated software, cracking tools, key generators, malicious advertisements, peer-to-peer (P2P) networks, drive-by downloads, the compromise of webpages, and the distribution of malevolent links or files via email, among various other techniques.

How To Remove NineRAT Malware?

Manual removal of the threat is possible, but it’s not recommended due to the malware’s persistence strategy, creating multiple instances that are challenging to trace efficiently. Manual removal can be time-consuming and have low to no efficiency.

The most effective approach to eliminate malware from your device is by using anti-malware software. I recommend GridinSoft Anti-Malware as it offers a fast, lightweight, and effective security solution capable of repelling threats like NineRAT.
