Iran-Linked MuddyWater Hackers Target U.S. Networks With New Dindoor Backdoor

Iran-Linked MuddyWater Hackers Target U.S. Networks With New Dindoor Backdoor

Mar 06, 2026 Cyber Warfare / Cloud Security
New research from Broadcom's Symantec and Carbon Black Threat Hunter Team has discovered evidence of an Iranian hacking group embedding itself in several U.S. companies' networks, including banks, airports, non-profit, and the Israeli arm of a software company. The activity has been attributed to a state-sponsored hacking group called MuddyWater (aka Seedworm). It's affiliated with the Iranian Ministry of Intelligence and Security (MOIS). The campaign is assessed to have begun in early February, with recent activity detected following U.S. and Israeli military strikes on Iran . "The software company is a supplier to the defense and aerospace industries, among others, and has a presence in Israel, with the company's Israel operation seeming to be the target in this activity," the security vendor said in a report shared with The Hacker News. The attacks targeting the software company, as well as a U.S. bank and a Canadian non-profit, have been found to p...
149 Hacktivist DDoS Attacks Hit 110 Organizations in 16 Countries After Middle East Conflict

149 Hacktivist DDoS Attacks Hit 110 Organizations in 16 Countries After Middle East Conflict

Mar 04, 2026 Cyber Warfare / Critical Infrastructure
Cybersecurity researchers have warned of a surge in retaliatory hacktivist activity following the U.S.-Israel coordinated military campaign against Iran , codenamed Epic Fury and Roaring Lion. "The hacktivist threat in the Middle East is highly lopsided, with two groups, Keymous+ and DieNet, driving nearly 70% of all attack activity between February 28 and March 2," Radware said in a Tuesday report. The first distributed denial-of-service (DDoS) attack was launched by Hider Nex (aka Tunisian Maskers Cyber Force) on February 28, 2026. According to details shared by Orange Cyberdefense, Hider Nex is a shadowy Tunisian hacktivist group that supports pro-Palestinian causes. It leverages a hack-and-leak strategy combining DDoS attacks with data breaches to leak sensitive data and advance its geopolitical agenda. The group emerged in mid-2025. In all, a total of 149 hacktivist DDoS claims were recorded targeting 110 distinct organizations across 16 countries. The attacks were...
Iran-Linked Hackers Mapped Ship AIS Data Days Before Real-World Missile Strike Attempt

Iran-Linked Hackers Mapped Ship AIS Data Days Before Real-World Missile Strike Attempt

Nov 20, 2025 Cyber Warfare / Threat Intelligence
Threat actors with ties to Iran engaged in cyber warfare as part of efforts to facilitate and enhance physical, real-world attacks, a trend that Amazon has called cyber-enabled kinetic targeting. The development is a sign that the lines between state-sponsored cyber attacks and kinetic warfare are increasingly blurring, necessitating the need for a new category of warfare, the tech giant's threat intelligence team said in a report shared with The Hacker News. While traditional cybersecurity frameworks have treated digital and physical threats as separate domains, CJ Moses, CISO of Amazon Integrated Security, said these delineations are artificial and that nation-state threat actors are engaging in cyber reconnaissance activity to enable kinetic targeting. "These aren’t just cyber attacks that happen to cause physical damage; they are coordinated campaigns where digital operations are specifically designed to support physical military objectives," Moses added. As an...

MSS Claims NSA Used 42 Cyber Tools in Multi-Stage Attack on Beijing Time Systems

MSS Claims NSA Used 42 Cyber Tools in Multi-Stage Attack on Beijing Time Systems

Oct 20, 2025 Cyber Espionage / National Security
China on Sunday accused the U.S. National Security Agency (NSA) of carrying out a "premeditated" cyber attack targeting the National Time Service Center ( NTSC ), as it described the U.S. as a "hacker empire" and the "greatest source of chaos in cyberspace." The Ministry of State Security (MSS), in a WeChat post , said it uncovered "irrefutable evidence" of the agency's involvement in the intrusion that dated back to March 25, 2022. The attack was ultimately foiled, it added. Established in 1966 under the jurisdiction of the Chinese Academy of Sciences (CAS), NTSC is responsible for generating, maintaining, and transmitting the national standard of time (Beijing Time). "Any cyberattack damaging these facilities would jeopardize the secure and stable operation of 'Beijing Time,' triggering severe consequences such as network communication failures, financial system disruptions, power supply interruptions, transportation paraly...
Europol Disrupts NoName057(16) Hacktivist Group Linked to DDoS Attacks Against Ukraine

Europol Disrupts NoName057(16) Hacktivist Group Linked to DDoS Attacks Against Ukraine

Jul 17, 2025 Hacktivism / Cybercrime
An international operation coordinated by Europol has disrupted the infrastructure of a pro-Russian hacktivist group known as NoName057(16) that has been linked to a string of distributed denial-of-service (DDoS) attacks against Ukraine and its allies. The actions have led to the dismantling of a major part of the group's central server infrastructure and more than 100 systems across the world. The joint effort also included two arrests in France and Spain, searches of two dozen homes in Spain, Italy, Germany, the Czech Republic, France and Poland, and the issuance of arrest warrants for six Russian nationals. The effort, codenamed Operation Eastwood, took place between July 14 and 17, and involved authorities from Czechia, France, Finland, Germany, Italy, Lithuania, Poland, Spain, Sweden, Switzerland, the Netherlands, and the United States. The investigation was also supported by Belgium, Canada, Estonia, Denmark, Latvia, Romania and Ukraine. NoName057(16) has been operatio...
