Florida water agency latest to confirm cyber incident as feds warn of nation

A ransomware gang hit Florida's St. Johns River Water Management District as CISA warned of IRGC-linked CyberAv3ngers attacks on exposed Unitronics water-sector PLCs.

The St. Johns River Water Management District, which oversees Florida drinking-water supply planning, confirmed suspicious activity in its IT environment and said containment measures were implemented; a ransomware gang claimed the attack and shared samples of stolen data. Separately, CISA, FBI, NSA, EPA and Israel's INCD warned that IRGC-affiliated CyberAv3ngers are actively compromising Israeli-made Unitronics Vision Series PLCs in the water sector using default credentials since at least November 22. The group, motivated by opposition to Israel-linked products, defaces controller interfaces and could cause deeper cyber-physical effects. Shadowserver found at least 539 Unitronics PLC instances still exposed online, and CNN reported fewer than 10 US water facilities faced recent attacks.

Coast Guard, FBI board US-bound foreign ships in order to probe for cyberattacks

US Coast Guard and FBI boarded two foreign tankers bound for the US after indications their vessel networks were compromised, investigating possible Iranian involvement.

The Coast Guard and FBI conducted joint offshore security boardings of two commercial ships in the Gulf of Mexico on August 21 and 24 to examine their operational and IT systems following indications both networks were compromised. The vessels reportedly carried oil and natural gas, and one was hacked in the Strait of Gibraltar and lost communications for over 30 hours. No operational disruptions, vessel instability, or environmental impacts have been reported, and authorities are investigating whether Iran or another group exploiting US-Iran tensions was behind the attacks.

CISA tells operators to harden Siemens S7 PLCs. Here’s how to do it without disrupting production

CISA, NSA, FBI and other agencies warn of active targeting of internet-exposed Siemens S7 PLCs and urge patching, exposure removal and hardening.

Joint advisory AA26-231A from the NSA, CISA, FBI, Department of Energy and EPA warns that actors are actively targeting Siemens S7 PLCs using internet scanning, AI-assisted scripts and libraries such as Snap7 and python-snap7 over S7comm on TCP port 102. The advisory covers S7-200 through S7-1500 series controllers and recommends patching, removing internet exposure, access controls, monitoring and disabling unneeded services. Siemens states no new S7 vulnerabilities are involved, only misconfigurations addressed in existing ProductCERT guidance SSB-104599. The article details how to apply each measure without breaking production dependencies such as remote I/O, HMI links and diagnostics.

US agencies warn of AI-powered attacks on Siemens industrial controllers

NSA, CISA, FBI, DOE, and EPA warn threat actors use AI-assisted scripts and snap7 libraries to access internet-exposed Siemens S7 PLCs in critical infrastructure sectors.

NSA, CISA, FBI, DOE, and EPA issued a joint advisory warning that threat actors combine open-source snap7.dll/python-snap7 libraries with AI-generated scripts to gain read/write access to Siemens S7-200 through S7-1500 PLCs over the S7comm protocol. Actors use Censys and ZoomEye to find internet-exposed devices and abuse default or weak credentials, with activity assessed as persistent reconnaissance and positioning for future write operations. Agencies urge device inventory, patching, removing PLCs from the internet, and hardening; the pattern resembles Iran-linked CyberAv3ngers targeting of Rockwell, Schneider, and Siemens PLCs.

Thomson Reuters reveals breach that exposed U.S. and Canadian court records

Thomson Reuters disclosed a C-Track breach exposing court records and personal data across at least 12 US states, US Virgin Islands, and Canada.

Thomson Reuters discovered unauthorized activity in its C-Track court case management platform on June 30, 2026, tracing the intrusion to March 2026. Affected systems include Ontario's three courts, Wyoming's entire state judiciary, and appellate and supreme courts across at least 12 US states plus the US Virgin Islands. Exposed records may include names, Social Security numbers, driver's license numbers, medical information, dates of birth, and health insurance details, with some sealed court information possibly affected. The company is offering 12 months of free credit monitoring and reports no evidence of fraud so far; attribution and access method remain unknown.

AI-Generated Exploit Scripts Target Siemens S7 PLCs in U.S. Critical Infrastructure

NSA, CISA, FBI, DOE and EPA warn that actors use AI-generated Python scripts to exploit internet-exposed Siemens S7 PLCs at U.S. critical infrastructure.

A joint advisory from NSA, CISA, FBI, DOE and EPA describes an active threat in which AI-generated exploit scripts disguised as legitimate monitoring tools target Siemens S7 Series PLCs (S7-200 through S7-1500, including F-series safety controllers). The actors use Censys and ZoomEye scanning to find internet-exposed, outdated PLCs and a custom Python script using snap7 libraries over the S7comm protocol for initial access, credential access and denial of service; no attribution was given. Targeted sectors include Critical Manufacturing, Energy, Water and Wastewater, Chemical, Food and Agriculture, and Commercial Facilities, with potential for process disruption and cascading impacts. A related Dream report details a near-autonomous AI-agent campaign (July 1-4, 2026, 12 waves) against Taiwan government entities, using Hermes and OpenClaw agents with eight parallel sub-agents to crack 85 accounts via password spraying and exfiltrate over 2,564 personnel records, SSO client secrets and database credentials.
