DieNet: A Rising Hacktivist Group Targeting Critical Infrastructure

DieNet: A Rising Hacktivist Group Targeting Critical Infrastructure

Originally published: 04/07/2025

I. Targeted Entities

  • Energy Sector
  • Healthcare Sector
  • Transportation Sector
  • Financial Services
  • Critical Infrastructure
  • Telecommunications
  • Higher Education

II. Introduction

DieNet first emerged on March 7th, 2025. According to Radware, a global cybersecurity and application provider, it has reported 61 attacks against 19 United States organizations. DieNet has also claimed 17 attacks against many organizations in countries such as Iraq, the Netherlands, Egypt, and Israel. DieNet is known to target critical infrastructure, particularly in the sectors of transportation, energy, finance, telecommunications, and healthcare. DieNet has been seen carrying out Distributed Denial of Service (DDoS) attacks against organizations to gain headline attention as a form of protest. They have targeted military and government entities around the time of political decisions.

  • This hacktivist group has many political and social motives. They have started to be anti-Trump and anti-Zionist. Some pro-Palestinian hacktivist groups have endorsed DieNet, sharing the same ideologies and frameworks. It appears that any organizations or groups that support the United States President Donald Trump or receive federal funding are targets. These cybercriminals often frame their attacks as retaliation for military actions or political decisions.
  • This group includes bold, aggressive messages, threats, and taunts in their attacks. These bold and aggressive messages include statements such as “We are watching you”. These attacks are strategically carried out to maximize visibility. It has been noted that the persistence observed in these DDoS attacks would be nearly impossible for most botnets. These attacks are short but fierce, taking down and defacing websites and services.

III. Additional Background Information

  • Hacktivists are individuals or groups who conduct cyberattacks to raise awareness of specific political, social, religious, or global causes. These actions are carried out to gain visibility or to make a statement, supporting the cause they promote. Hacktivism is carried out in many forms, such as Distributed Denial of Service (DDoS) attacks, doxing, and website defacement. DDoS attacks work by using multiple botnets, which can be distributed across various geographic locations, to flood an organization's server infrastructure with traffic, making resources unavailable. This can cause large disruptions in service. Botnets are networks of computers that have been infected with malware, hijacked, and now carry out various cyberattacks. These are particularly important for large Distributed Denial of Service (DDoS) attacks, which require significant computing power.
  • DieNet stated on Telegram, a messaging service commonly used by this group’s members, that DieNet v2 has begun service, which includes larger botnets and increased membership. Currently, a report from the Center for Internet Security stated that another Telegram message from DieNet was released on March 21st, claiming they had breached a United States Federal Government agency and acquired government employees' Personally Identifiable Information (PII). If this claim becomes verified, it could result in a large escalation of DieNet’s Tactics, Techniques, and Procedures (TTPs).
  • At the time of this being written, Recorded Future, a leading cyber threat intelligence platform, has seen DieNet carry out suspected attacks in the United States against the Port of Los Angeles, Chicago Transit, Lumen Technologies, the North American Electric Reliability Corporation, U.S. Department of Commerce, International Trade Administration, Nasdaq, Inc., Northeastern University, Meditech, Pacific Gas and Electric Company, WaterOne, CoinBase, the National Emergency Medical Services Information System, U.S. Postal Service, Epic Systems, NASA, Veterans of Foreign Wars, FBI Crime Data Explorer, X, Axos Bank, Lyft, ProductionHUB, and Azure.
  • Although there is currently limited information, as this group was established less than 3 weeks ago at the time of this advisory, the exploit appears to use tactics defined in the MITRE ATT&CK framework, such as T1498, Network Denial of Service, and T1491.002, Defacement: External Defacement.
  • Previous DDoS attacks that involve hacktivists bring major concern to the target industries as these attacks can cause service interruptions, societal concern, and financial losses.
  • Organizations are strongly urged to maintain proper security practices. These practices should include security awareness training, applying the latest patches, and monitoring for indicators of compromise (IoC). Failure to follow these procedures could result in severe disruptions and possible data breaches.

IV. MITRE ATT&CK

  • T1498-Network Denial of Service
    This type of attack involves the adversary blocking access to targeted resources for users of a system. In this case, the adversary exhausts the network bandwidth, rendering websites and services unavailable.
  • T1491.002-Defacement: External Defacement
    This type of sub attack is used to deface the external systems of a group or organization to display a message. In this case, DieNet is using this to intimidate organizations and gain visibility.

V. Recommendations

  • Implement a Defense-In-Depth Strategy
    • Implement many different layers of security. This can include reducing your organization’s DDoS attack surface by restricting access to areas and blocking communication on unused or insecure ports, protocols, and services. Other layers include configuring Endpoint Detection and Response (EDR) software, firewalls, and robust Anti-Virus (AV) to all devices and systems. Always perform both online and offline backups. Performing both will ensure that copies of data are in various locations, one of which is inaccessible to the attacker.
  • Apply Rate Limiting and Load Balancers
    • Rate limiting sets a threshold on how often an action can be repeated within a given time frame. Implementation of rate limiting through network configuration settings can help prevent botnet activity. Load Balancers are the first line of defense against DDoS attacks. Having proper load balancers in place will also ensure your websites and services remain available during a DDoS attack. In the event of a DDoS attack, load balancers can distribute traffic across multiple servers, allowing the ability for services to remain available in some cases.
  • >Implement a Web Application Firewall (WAF)
    • A WAF operates dynamically, using custom policies tailored to your organization's environment to filter and analyze network traffic. The WAF can adapt by adding new policies to combat emerging attacks and continuously monitoring network traffic for changes.
  • Establish an Incident Response Plan
    • Create or revise an incident response plan that includes steps for handling a Denial of Service or Distributed Denial of Service attack. The reaction team should also be equipped and trained to handle any potential breaches.

VI. Indicators of Compromise (IOCs)

The attacks being carried out by DieNet are constantly evolving, have botnets that span the globe, use encrypted traffic, and employ legitimate IP addresses, making it incredibly difficult to find reliable IoCs.
