DCRat, also known as Dark Crystal Rat has been around since 2018. It operates as a modular remote access trojan (RAT) offered as a Malware-as-a-Service (MaaS) and has garnered attention due to its cost-effectiveness and adaptability.
The malware is purpose-built to provide threat actors unauthorized access to systems by circumventing security measures. DCRat stands out as a versatile tool suitable for various malicious activities, including:
- Surveillance: DCRat enables monitoring and data collection from targeted devices.
- Reconnaissance: It aids in gathering information about a victim’s network and connected devices.
- Information Theft: DCRat is adept at pilfering sensitive data from victimized systems.
- DDoS Attacks: It can be employed to initiate Distributed Denial of Service (DDoS) attacks against specific websites.
- Dynamic Code Execution: DCRat offers the ability to execute code in multiple programming languages.
DCRat’s components consist of a stealer/client executable, a single PHP page that serves as the command-and-control (C2) interface, and an administrator tool.
It has been observed targeting Russian-speaking victims, particularly by installing crypto-mining software on their endpoints, among other malicious purposes. DCRat boasts a modular structure and a tailored plugin framework, enhancing its adaptability and attractiveness to attackers.
Common targets of DCRat malware encompass:
- Telegram Accounts: DCRat has been detected targeting Telegram accounts, possibly due to the messaging app’s prevalence in Russia.
- Windows Systems: DCRat provides comprehensive backdoor access to Windows systems, with a specific focus on bypassing security safeguards.
- Crypto-Mining: Instances of DCRat deploying crypto-mining software on victim endpoints have been documented.
- DDoS Attacks: It possesses the capability to launch DDoS attacks against selected websites.
- Information Theft: DCRat can facilitate the theft of sensitive data from victim devices, including capturing screenshots, harvesting clipboard data, and executing keylogging functions.
DCRat Delivery Methods
DCRat malware employs various methods for distribution, which encompass:
- Adult Content-Themed Lures: DCRat has been disseminated through enticing adult content-themed baits, including explicit references to OnlyFans pages and other adult-oriented material.
- Malware-as-a-Service: DCRat operates as a Malware-as-a-Service (MaaS), permitting its purchase and utilization by threat actors and then spreading in the threat actors choosing delivery method.
- Infected Files: DCRat can be propagated via corrupted files, such as ZIP archives harboring a malicious payload.
- Network Propagation: When a device is compromised and connected to a network, the malware can proliferate to other devices sharing the same network.
DC Rat Impact
The impact of DCRat malware can have significant consequences, including:
- Compromised sensitive information: DCRat can stealthily steal sensitive data from a victim’s device, including capturing screenshots, harvesting clipboard contents, and recording keystrokes.
- Financial losses: By installing crypto-mining software on a victim’s device, DCRat can lead to financial losses stemming from increased energy expenses and decreased device performance.
- DDoS attacks: DCRat can orchestrate DDoS attacks against targeted websites, resulting in website unavailability and subsequent financial losses for affected organizations.
- Productivity decline: Infected devices may experience slowdowns or become inaccessible, causing delays and downtime that adversely affect productivity.
- Reputation damage: A successful DCRat malware attack can tarnish the impacted organization’s reputation, especially if sensitive data is compromised or the organization cannot deliver services to its customers.
