CISA urged water utilities to secure internet-exposed PLCs after July 2026 attacks compromised over 100 US water and wastewater systems, suspected Iran-linked.
CISA's exposure-reduction guidance, published August 21, follows July 2026 attacks in which threat actors remotely accessed PLCs connected directly through cellular modems, changed device IP addresses and passwords, and in some cases disabled alarms and shutdown processes without notifying operators. Iran is the suspected actor, though officials stopped short of formal attribution. CISA recommends routing remote access through centrally managed secure gateways, phishing-resistant MFA, unique credentials, and external scanning of industrial protocols such as Modbus, EtherNet/IP, DNP3, BACnet and OPC UA.

Hackers encrypted the central IT network of Bavarian utility Stadtwerke Landsberg, disrupting office systems but not electricity or water services.
Stadtwerke Landsberg said hackers encrypted its central IT network overnight on Sept. 1, prompting disconnection from the internet, crisis-team activation and external forensic support. Essential electricity and water services were unaffected, but staff availability was limited and customer data such as names, addresses and bank details may have been accessed. No ransomware group was named and no extortion demand was confirmed. The attack follows a similar late-June encryption incident at a North Rhine-Westphalia municipal utility, and the BSI consistently ranks ransomware among Germany's most serious cyber threats.
Massachusetts executive order requires data centers over 25 MW to supply 100% clean power, fund nearby generation, or pay a ratepayer protection fund.
Governor Maura Healey's executive order requires developers building data centers larger than 25 megawatts of peak demand to bring their own power that meets 100% of the state's clean energy standard, fund new generation nearby, or pay into a ratepayer protection fund. Massachusetts is the third state in three months to restrict data center development, following Texas utility audits (ERCOT) and New York's pause on 50 MW-plus projects. The state is also pausing applications for a data center sales tax exemption and directing communities to avoid non-disclosure agreements. Pro-AI super PAC Leading the Future, funded by Marc Andreessen, Ben Horowitz, and Greg Brockman, is running ads ahead of midterms as industry pushes back.

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.

Palo Alto Unit 42 analyzes updated CryptoBit ransomware distributed via the Rig exploit kit, documenting IOCs, eight sample hashes, and disguise tactics from June 2016.
Unit 42 observed an updated CryptoBit ransomware variant (also tracked as CriptoBit or Mobef) delivered through the Rig exploit kit via the gate domain realstatistics.info between June 17-27, 2016. Infections targeted Windows hosts with out-of-date Flash plugins, and post-infection callbacks used fake user-agents and referrers to disguise traffic to laoismacau.com. At least eight samples were collected, and by June 27 the campaign had begun distributing other malware.
