In a groundbreaking discovery, Aqua Nautilus researchers recently uncovered a widespread Distributed Denial-of-Service (DDoS) campaign orchestrated by the Matrix threat actor. This campaign, a stark example of how accessible tools and minimal technical expertise can enable devastating cyberattacks, leverages vulnerabilities and misconfigurations in Internet of Things (IoT) devices and enterprise systems to create a formidable botnet capable of global disruption.
Key Takeaways
- A Comprehensive Cyberattack Framework: Matrix showcases a “do-it-all-yourself” approach, encompassing scanning, exploiting vulnerabilities, deploying malware, and setting up shop kits.
- Amplified Threat of Script Kiddies: While Matrix exhibits traits of a script kiddie, the integration of AI tools and plug-and-play hacking resources has elevated their threat potential.
- A Shift in DDoS Targets: Beyond IoT devices, this campaign targets development and production servers, signaling an alarming focus on enterprise-level vulnerabilities.
- Business-Driven Motives: Despite signs of Russian affiliation, the lack of Ukrainian targets underscores financial gain as the primary motivation.
Initial Access Vectors
Matrix’s campaign capitalizes on publicly available scripts, brute-force attacks, and default or hardcoded credentials, focusing on:
- Routers: Exploiting vulnerabilities like CVE-2017-18368 and CVE-2021-20090.
- Surveillance Devices: Leveraging weaknesses in DVRs and IP cameras using the Hi3520 platform.
- IoT Devices: Targeting default configurations in devices running lightweight Linux distributions.
- Enterprise Systems: Attacking vulnerabilities in Apache Hadoop’s YARN and HugeGraph servers.
Analysis of Misconfigurations and Vulnerabilities
- Misconfigurations: The campaign exploits weak passwords and exposed files on HTTP servers, with over 80% of compromised passwords belonging to root or admin users.
- Vulnerabilities: 10 CVEs were identified, including:
- CVE-2024-27348 (HugeGraph server)
- CVE-2022-30525 (Zyxel devices)
- CVE-2018-9995 (Hi3520 DVR devices)
Matrix’s Infrastructure and Toolbox
Matrix leverages an arsenal of open-source tools and malware, including:
- Mirai Botnet: Targeting IoT devices for large-scale DDoS attacks.
- Discord Bots: Utilizing DiscordGo for encrypted communication and command execution.
- SSH Scanners and PyBots: Detecting and exploiting misconfigured SSH access.
- HTTP/HTTPS Flood Attacks: Employing JavaScript-based scripts for targeted Layer 7 attacks.
Selling DDoS Services
Matrix monetizes its capabilities through a Telegram bot, “Kraken Autobuy,” offering various tiers of attack plans. Payment is facilitated via cryptocurrency, further anonymizing transactions.
Impact Assessment
The repercussions of the Matrix campaign extend beyond its direct victims:
- Service Disruptions: Large-scale DDoS attacks impair server functionality, impacting businesses and cloud vendors.
- Cryptomining: Although financially negligible (e.g., mining 1 ZEPHYR worth $2.70), it highlights the diversified use of compromised systems.
Mapping to the MITRE ATT&CK Framework
Matrix employs a range of techniques mapped to the MITRE ATT&CK framework, such as:
- Initial Access: Exploiting public-facing applications (T1190).
- Execution: Deploying Python-based scripting tools (T1059.006).
- Command & Control: Using encrypted communication channels (T1573).
Detection and Mitigation
Organizations can protect against campaigns like Matrix by:
- Strengthening Password Policies: Eliminate default credentials and enforce strong passwords.
- Timely Patch Management: Apply updates to address known vulnerabilities.
- Enhanced Network Monitoring: Utilize honeypots and intrusion detection systems to identify abnormal activities.
Indications of Compromise (IoCs)
Key IoCs include:
- IP Addresses: e.g., 199.232.46.132 (C2 server).
- Domains: sponsored-ate.gl.at.ply.gg (C2 server).
- Malware Samples: Various tools such as Mirai variants (e.g., MD5: df521f97af1591efff0be31a7fe8b925).
The Matrix campaign serves as a wake-up call to the cybersecurity community, emphasizing the need for proactive defenses and robust security practices. The growing sophistication and accessibility of attack tools mean that no organization or individual can afford to ignore basic security hygiene.
This analysis underscores the urgency to address systemic vulnerabilities and adopt a holistic approach to cybersecurity in the face of evolving threats.
