Denmark Attributes Two Destructive Cyberattacks to Russia

🔒 The Danish Defence Intelligence Service (DDIS) publicly attributed two separate cyber operations to Russian-linked actors. It said a pro-Russian group known as Z-Pentest carried out a destructive intrusion against a Danish water utility in 2024, while NoName057(16), an actor with ties to the Russian state, mounted disruptive DDoS attacks against Danish websites ahead of municipal and regional elections in November. Danish authorities characterized the incidents as part of a broader pattern of state-aligned cyber coercion and disruption.

FCC Bans Foreign-Made Drones and Critical Components

🚫 The FCC has placed foreign-made uncrewed aircraft systems (UAS) and critical UAS components on its Covered List, citing national security concerns and provisions of the 2025 NDAA. The action targets China-made vendors such as DJI and Autel Robotics and covers communications, flight controllers, navigation systems, batteries, motors, and related parts. The agency said the move will reduce risks of unauthorized surveillance, data exfiltration, and destructive operations over U.S. territory while permitting DHS to exempt specific models and allowing continued use and sale of previously approved devices.

Raspberry Pi Attack Exposes Gaps in Physical Security

🔌 A Raspberry Pi with a cellular modem was discovered plugged into a French ferry's internal network as it prepared to sail from Sète to Algeria; investigators told Bloomberg that network segmentation and the absence of remote access to critical controls prevented lateral movement and possible sabotage. Security experts warn such rogue devices can create a new internal perimeter that bypasses monitored gateways and render SOCs blind if traffic exits over cellular. Recommended mitigations include 802.1X authentication, disabling unused switch ports by default, physical port locks and tamper-evident measures, deployment of advanced NACs and physical-layer fingerprinting tools like Sepio, and capturing a device's network traffic for forensic analysis before physical removal.

Raspberry Pi on Ferry Prompts CISO Wake-Up on Security

🔒 In mid-December, a Raspberry Pi paired with a cellular modem was found attached to a ferry owned by the Mediterranean Shipping Company, apparently intended to give remote access to the vessel’s internal network. Robust segmentation and disabled remote access to critical control systems prevented lateral movement and a potential sabotage scenario. Analysts warn many organizations remain vulnerable because physical security and port-level controls are often overlooked, and they recommend stronger NAC, 802.1X enforcement, port locks, and continuous external infrastructure monitoring.

Deliberate Internet Shutdowns: Rising Global Trend

🌐 The Taliban ordered a two‑day nationwide internet blackout in Afghanistan in September, cutting emergency communications, grounding flights, and interrupting banking. That incident is part of a global surge: Access Now and the #KeepItOn coalition documented 296 deliberate shutdowns in 2024 and at least 244 more in 2025 so far. Shutdowns range from full national cuts to targeted platform blocks and throttling, and are increasingly used for political, military, and social control. Workarounds like VPNs, mesh networks, and satellite terminals help some, but for most people loss of connectivity means loss of essential services and civil liberties.

Russian APT Targets Energy and Critical Infrastructure

🔎 Amazon Threat Intelligence reports a Russian state-sponsored cyber espionage team has increasingly targeted energy providers and other critical infrastructure, operating since at least 2021. The actors have shifted toward exploiting device misconfigurations while continuing to leverage known vulnerabilities such as CVE-2022-26318, CVE-2021-26084, CVE-2023-22518 and CVE-2023-2753. Observed tradecraft includes compromise of network-edge devices hosted on AWS EC2, passive credential capture and credential-replay attacks to move laterally across victim environments. Amazon provides indicators of compromise and specific mitigation guidance, including configuration audits, isolation of management interfaces and deployment of multi-factor authentication.

Russian APT Shifts to Network Edge Device Misconfigurations

🔍 A Russian state-sponsored cyberespionage group has shifted to exploiting misconfigurations in network-edge devices to target energy companies and critical infrastructure. Amazon Threat Intelligence found the actor, active since at least 2021, pivoted from known CVEs to passive credential harvesting via compromised routers, VPN concentrators and management appliances. Telemetry shows overlaps with GRU-linked Sandworm and Bitdefender’s Curly COMrades, with attackers intercepting traffic to replay credentials. Amazon urges audits of edge devices, isolation of management interfaces, enforcement of MFA and monitoring for anomalous authentication.

Amazon Reveals Years-Long GRU Campaign Targeting Energy

🛡️ Amazon's threat intelligence team disclosed a years-long campaign tied with high confidence to the GRU-affiliated APT44 (also tracked as FROZENBARENTS/Sandworm), which targeted Western critical infrastructure from 2021–2025. The actor shifted from zero-day exploitation to abusing misconfigured customer network edge devices and exposed management interfaces on AWS-hosted instances, enabling packet capture, credential harvesting, and credential replay against energy, telecom, and cloud providers. Amazon observed exploitation of WatchGuard (CVE-2022-26318), Atlassian Confluence (CVE-2021-26084, CVE-2023-22518), and Veeam (CVE-2023-27532), notified affected customers, disrupted active operations, and recommended audits, stronger authentication, and monitoring for unexpected access and credential replay.

Güralp Web Interface DoS Vulnerability (CVE-2025-14466)

⚠️ A vulnerability in the web interface of Güralp Systems Fortimus, Minimus, and Certimus Series (CVE-2025-14466) allows an unauthenticated network attacker to send specially crafted HTTP requests that cause the web service process to restart. The restart produces a brief denial-of-service condition with a CVSS v3.1 base score of 5.3 (Medium). Güralp recommends operating affected systems behind a NAT or VPN firewall and contacting the vendor for further guidance. CISA advises minimizing network exposure, isolating control networks, and using secure, up-to-date remote access methods.
