CyberAv3ngers' Cyberattacks on U.S. Water Systems: A 2026 Analysis
In July 2026, a coordinated series of cyberattacks targeted water and wastewater systems across at least 12 U.S. states, including Minnesota, Georgia, Michigan, South Dakota, Alabama, and New Jersey. The attackers exploited vulnerabilities in internet-exposed programmable logic controllers (PLCs), specifically those from Rockwell Automation, Schneider Electric, and Siemens, to modify configurations and lock out operators. While no water contamination was reported, some systems experienced operational disruptions, such as water pressure drops and the issuance of boil water advisories. These incidents underscore the critical vulnerabilities in the nation's water infrastructure, particularly in smaller utilities lacking robust cybersecurity measures. ([axios.com](https://www.axios.com/2026/08/04/water-cyberattacks-us-iran?utm_source=openai)) The attacks have been tentatively linked to the Iranian state-sponsored group CyberAv3ngers, known for targeting industrial control systems in critical infrastructure sectors. This campaign highlights the escalating cyber threat landscape and the urgent need for enhanced security protocols to protect essential services.

Gunra Ransomware Exploits Fortinet and Schneider Electric Vulnerabilities
In August 2026, cybersecurity agencies from South Korea and the U.S. issued warnings about Gunra ransomware attacks targeting critical infrastructure sectors worldwide. The attackers exploited vulnerabilities in Schneider Electric PowerLogic P5 (CVE-2024-5559) and Fortinet FortiOS and FortiProxy (CVE-2025-24472) appliances to gain initial access. Employing a double extortion model, they encrypted data and exfiltrated sensitive information, threatening to publish it unless a ransom was paid within five to seven days. Since its emergence in April 2025, Gunra has listed 51 victims, primarily in South Korea, Brazil, Spain, Thailand, and Hong Kong. The group utilizes phishing campaigns and advanced encryption methods like Salsa20 and ChaCha20 to execute their attacks. This incident underscores the evolving tactics of ransomware groups, highlighting the critical need for organizations to promptly patch known vulnerabilities and implement robust security measures to protect against such sophisticated threats.

Malicious SIM Cards Exploit IoT Device Modems - August 2026
In August 2026, researchers from the University of Birmingham and security firm Fuzzware discovered that malicious SIM cards can execute attacker-controlled commands within the modems of cellular IoT devices, such as electric vehicle chargers, industrial routers, and car telematics units. Testing 26 devices, they found that 9 were vulnerable, including certain models from OPPO and ASUS. The vulnerability stems from the 'RUN AT' proactive command, which allows a SIM card to instruct the modem to execute AT commands, potentially leading to full device compromise. This issue predominantly affects machine-to-machine hardware, with several Quectel modules identified as susceptible. The researchers recommend disabling or hardening the 'RUN AT' interface to mitigate this risk. This discovery underscores the critical need for robust security measures in IoT devices, especially as they become more integrated into essential infrastructure. The ability for a SIM card to control device modems highlights a significant attack vector that could be exploited if not properly addressed.

Gunra Ransomware Group: A Growing Global Threat
In August 2026, U.S. and South Korean cyber agencies issued a joint advisory regarding the Gunra ransomware group, a ransomware-as-a-service (RaaS) operation that has been active since April 2025. Gunra employs double-extortion tactics, encrypting victims' data and threatening to publish it unless a ransom is paid. The group has targeted a wide range of sectors, including academia, financial services, government facilities, healthcare, manufacturing, and utilities, across multiple continents. Notably, Gunra has been recruiting ethical hackers and penetration testers as initial access brokers, offering them a share of the ransom profits in exchange for access to enterprise networks. This advisory underscores the evolving nature of ransomware threats, highlighting the increasing sophistication of RaaS operations and their global reach. Organizations are urged to bolster their cybersecurity defenses, particularly by addressing known vulnerabilities in internet-facing devices and implementing robust access controls to mitigate the risk of such attacks.

Cyberattack on Polish Energy Plant via Private APN Highlights Infrastructure Vulnerabilities
In December 2025, a coordinated cyberattack targeted Poland's energy infrastructure, including a small combined heat and power (CHP) plant supplying heat to approximately 50,000 residents. The attackers exploited a misconfigured private Access Point Name (APN) to access the plant's operational technology (OT) network. By compromising a WAGO PFC200 programmable logic controller (PLC) with default credentials, they gained control over the plant's systems, leading to the shutdown of the steam turbine and water treatment system. The plant's staff managed to restore operations swiftly, preventing significant disruption to the population. This incident underscores the evolving tactics of nation-state actors in targeting critical infrastructure. The use of private APNs as attack vectors highlights the necessity for robust network segmentation, stringent access controls, and regular security assessments to mitigate such threats.

Cyberattacks Reveal Critical Vulnerabilities in U.S. Water Systems
In late July 2026, a series of cyberattacks targeted water and wastewater systems across at least 12 U.S. states, including Michigan, South Dakota, and Georgia. Attackers exploited internet-exposed Rockwell Automation and Allen-Bradley programmable logic controllers (PLCs), specifically the MicroLogix 1100 and 1400 models, to remotely alter configurations, leading to operational disruptions such as pressure loss and flooding. Despite prior federal warnings, over 4,000 such controllers remained accessible online, with 2,844 located in the United States. This incident underscores the persistent vulnerabilities in critical infrastructure due to inadequate cybersecurity measures. The exploitation of known vulnerabilities in widely used industrial equipment highlights the urgent need for enhanced security protocols and the removal of operational technology from direct internet exposure to prevent future attacks.

Over 4,400 Rockwell PLCs Exposed Online: A Wake-Up Call for Critical Infrastructure Security
In August 2026, Forescout identified 4,407 internet-exposed Rockwell Automation programmable logic controllers (PLCs) worldwide, with 2,844 located in the United States. Notably, 22 of these exposed PLCs were found in cities recently targeted by cyberattacks on U.S. water utilities, with 19 utilizing the same mobile carrier network. Attackers exploited these vulnerabilities by altering IP addresses and setting passwords on accessible controllers, leading to operators losing visibility and control over connected equipment. This incident underscores the critical need for securing industrial control systems against unauthorized internet exposure. The prevalence of internet-exposed PLCs highlights a significant security gap in critical infrastructure, particularly within the water sector. The ease with which attackers can manipulate these systems without exploiting specific vulnerabilities emphasizes the urgency for organizations to implement robust network segmentation, remove unnecessary internet exposure, and enforce strong authentication measures to protect against potential disruptions and threats to public safety.
