Chinese UNC3886 Cyberspies Breach Singapore Telcos

🔒 Singapore's Cyber Security Agency says China-linked threat actor UNC3886 breached the country's four largest telcos — Singtel, StarHub, M1, and Simba — at least once last year, gaining limited access to critical systems but failing to disrupt services or exfiltrate confirmed customer data. Investigators found a zero-day used to bypass perimeter firewalls and rootkits employed for stealth and persistence. The government launched Operation Cyber Guardian, mobilized multiple agencies, and contained the intrusions while increasing monitoring across critical sectors.

China-linked UNC3886 Targets Singapore Telecoms Systems

🛡️ Singapore's Cyber Security Agency (CSA) disclosed that the China-linked espionage group UNC3886 executed a deliberate, targeted campaign against the nation's telecommunications sector, naming M1, SIMBA Telecom, Singtel and StarHub as targets. The agency said the actor used sophisticated tools, including a weaponized zero-day and kernel-level rootkits, to gain unauthorized access to portions of telco networks. CSA reported no evidence of customer personal data exfiltration or service disruption and said a defensive operation called CYBER GUARDIAN has closed the group's access points and expanded monitoring across affected operators.

Mitsubishi MELSEC iQ-R Series Critical Firmware Flaw

⚠️ A critical vulnerability (CVE-2025-15080) affects Mitsubishi Electric MELSEC iQ-R Series firmware (R08/16/32/120PCPU) versions 48 and earlier. An attacker can read device data or parts of control programs, write device data, or cause a denial-of-service by sending specially crafted SLMP or proprietary protocol packets. Mitsubishi Electric recommends updating affected firmware to version 49 or later and, until patched, restricting access via firewalls, IP filters, VPNs, and LAN-only operation.

Germany and Israel Conduct Joint Cyberattack Defense Drill

🛡️ Germany and Israel jointly conducted a first-ever exercise, called “Blue Horizon,” to practice defending against a major cyberattack as part of a recent bilateral cyber and security pact. The drill aims to familiarize experts and advance the planned construction of a German “Cyberdome”, modeled on Israeli systems that consolidate data and use AI to detect network vulnerabilities and warn organizations. The pact also foresees closer cooperation on cybercrime, artificial intelligence and drone defense.

Poland Attributes December Cyber Attacks to Static Tundra

🔒 CERT Polska disclosed coordinated, destructive cyber attacks on December 29, 2025 that targeted more than 30 wind and photovoltaic farms, a manufacturing firm, and a large combined heat and power (CHP) plant. The agency attributed the activity to the cluster it calls Static Tundra, linked to Russia's FSB Center 16, while other vendors noted similarities to Sandworm. Attackers deployed multiple wipers — notably DynoWiper and a PowerShell-based LazyWiper — exploited vulnerable FortiGate appliances, harvested credentials and exfiltrated selected M365 data, but did not succeed in disrupting electricity production or heat delivery.

FBI Launches Winter SHIELD to Strengthen Cyber Defenses

🔐 The FBI has launched Operation Winter SHIELD, a ten-week campaign outlining ten concrete actions organisations should adopt to improve cyber resilience across IT and OT environments. Developed with domestic and international partners and informed by recent investigations, the initiative connects observed adversary behaviour to practical defenses such as phish-resistant authentication, immutable offline backups, vulnerability management and reduced administrator privileges. Aligned with the US National Cyber Strategy and the FBI Cyber Strategy, the effort aims to harden critical infrastructure and reduce the attack surface.

CISA Issues New Guidance on Insider Threat Risk Management

🔒 The US Cybersecurity and Infrastructure Security Agency (CISA) has released an infographic to help critical infrastructure operators and SLTT governments prevent, detect and respond to insider threats. It advocates treating insider risk as an essential capability and recommends scalable, multidisciplinary teams that are embedded in existing structures. The guidance outlines a four-stage model—plan, organize, execute, maintain—and emphasizes confidentiality, legal compliance and coordination with external partners.

Criticism of Kritis Umbrella Law Raises Patchwork Concerns

⚠️ The German Association of Cities warns the coalition's proposed Kritis umbrella law, due for a Bundestag vote, is insufficient because its 500,000‑inhabitant threshold excludes many essential facilities and weakens crisis preparedness. The draft tightens obligations for classified operators — including reporting duties and fines — but the Städtetag urges lowering the cutoff to 150,000 to cover medium-sized municipalities. The association also warns that allowing federal states to designate additional facilities risks creating a fragmented patchwork. In response to a January power-supply arson in Berlin, the amendment asks the government to review and remove publicly available infrastructure data to limit attacker intelligence, a shift Chancellor Friedrich Merz framed as moving from broad transparency toward greater resilience.

Coordinated Cyberattack on Polish Energy Grid Hits 30 Sites

⚠️ A coordinated late-December cyberattack targeted distributed energy resource (DER) sites across Poland, impacting roughly 30 facilities including combined heat and power (CHP) plants and wind and solar dispatch systems. Researchers at Dragos say attackers damaged OT equipment beyond repair and wiped Windows hosts while disabling remote monitoring, though generation continued and no outages occurred. Dragos links the operation with moderate confidence to the cluster it calls Electrum, noting overlaps with Sandworm/APT44 and ties to destructive wipers used in Ukraine.
