Rolling Networks: Securing Cyber Risks in Transport

🚚 Modern trucks are "rolling networks" loaded with communications systems, sensors, cloud-connected devices and Wi-Fi, creating expansive attack surfaces. Ben Wilkens of NMFTA warns that cybercriminals exploit the sector’s uptime pressure with ransomware, extortion and cyber-enabled cargo theft. Core hygiene—MFA, network segmentation, social engineering training and timely patching—can significantly reduce risk but must be adapted for small carriers. NMFTA advances research, guidance and an annual conference to help the industry collaborate and strengthen defenses.

Iran-Backed Hackers Target US CNI via Internet-Facing OT

⚠ Iranian-affiliated threat actors have been exploiting internet-facing operational technology (OT) assets to target US critical national infrastructure (CNI) providers since late March, according to a CISA advisory. Attackers used vendor configuration tools such as Rockwell Automation's Studio 5000 Logix Designer to create accepted connections to PLCs and manipulated HMI/SCADA displays. Observed inbound traffic used ports 44818, 2222, 102, 22 and 502 and included deployment of Dropbear SSH for remote access. Agencies urge immediate log review, segmentation, and removal of direct internet exposure for PLCs.

Iran-Linked Hackers Disrupt U.S. OT Devices and PLCs

🔒 Iran-affiliated cyber actors are targeting internet-facing operational technology (OT) devices across U.S. critical infrastructure, including energy, water and government facilities. U.S. agencies warn attackers used third-party hosted infrastructure and Rockwell Automation tools to connect to CompactLogix and Micro850 PLCs, deploy Dropbear SSH, extract project files, and manipulate HMI/SCADA displays, causing degraded functionality and disruption. Organizations are advised to remove internet exposure, enforce multi-factor authentication, place firewalls or proxies in front of PLCs, disable unused features, keep devices up to date, and monitor for anomalous traffic.

US: Iranian Hackers Target Internet-Exposed PLCs Nationwide

⚠️ U.S. agencies warn that Iranian-affiliated APT actors are actively targeting Internet-exposed Rockwell/Allen-Bradley and other PLCs on networks supporting critical infrastructure sectors such as Water, Energy, and Government Services. The joint advisory from the FBI, CISA, NSA, DOE, EPA, and U.S. Cyber Command states intrusions since March 2026 have caused operational disruption, extraction of device project files, and manipulation of HMI/SCADA displays. Organizations are advised to disconnect PLCs from the Internet or protect them behind firewalls, apply the latest firmware, enable multifactor authentication for OT access, disable unused services and default keys, and monitor OT ports and logs for the advisory's indicators of compromise.

UK NCSC: APT28 Hijacks Routers to Steal Credentials Globally

🔒 The UK’s National Cyber Security Centre (NCSC) warns that Russian-linked APT28 has been compromising vulnerable SOHO routers to redirect DNS traffic through attacker-controlled servers and harvest credentials. The actor has modified a list of VPS-hosted DNS servers since 2024 and exploited models including TP-Link (notably the WR841N via CVE-2023-50224) and MikroTik. The campaigns use DHCP DNS tampering and adversary-in-the-middle techniques; the NCSC and Microsoft advise firmware updates, multifactor authentication and network hardening.
