Network devices in at least one Norwegian organization
February 5, 2026
•[ state-sponsored espionage, network device compromise, telecom ]
The Record reported that Norways Police Security Service (PST) disclosed that the Chinese state-sponsored espionage campaign tracked as Salt Typhoon compromised network devices in Norwegian organizations. PST made the disclosure in its 2026 annual threat assessment and said the actor exploited vulnerable network devices, consistent with a broader telecom/critical infrastructure espionage focus described by allied authorities. The article does not identify specific victim organizations or provide incident-level dates/effects for one named target, so it is best treated as campaign-level reporting rather than a single victim event record.

•[ APT, vulnerability exploitation, state-sponsored attack ]
Security researchers reported that state-sponsored advanced persistent threat groups exploited a WinRAR vulnerability in real-world attacks that successfully compromised at least one government, military, and technology organization in Ukraine, using malicious archive files to gain unauthorized access to victim systems.
European Commission
January 30, 2026
•[ cyberattack, data leak, vulnerability exploitation ]
The European Commission disclosed it detected traces of a cyberattack on January 30, 2026 targeting its central infrastructure used to manage staff mobile devices. The Commission said the incident may have resulted in access to staff names and mobile phone numbers for some employees, but it had not found evidence that managed mobile devices themselves were compromised. The Commission stated its response contained and cleaned the system within nine hours. The article notes the Commission did not disclose the initial access method, but the incident appeared linked to attacks exploiting vulnerabilities in Ivanti Endpoint Manager Mobile (EPMM).

•[ vulnerability exploitation, command-and-control, persistence ]
BleepingComputer reported that threat actors exploited critical SolarWinds Web Help Desk (WHD) vulnerabilities (including CVE-2025-40551 and CVE-2025-26399) in a campaign believed to have started around January 16, 2026, targeting at least three organizations. Attackers used the access to deploy legitimate tools (Zoho ManageEngine Assist, Cloudflare tunnels, Velociraptor) for persistence and command-and-control.
At least one organization in Southeastern Europe
January 8, 2026
•[ cyber espionage, vulnerability exploitation, SSH brute force ]
BleepingComputer reported on Cisco Talos research describing a sophisticated China-nexus actor tracked as UAT-7290 targeting telecommunications providers, historically in South Asia and recently expanded into Southeastern Europe. The group was described as conducting extensive reconnaissance and using one-day exploits plus target-specific SSH brute force to compromise public-facing edge devices for initial access and privilege escalation. Talos reported the actor deploys a primarily Linux-based malware suite (with occasional Windows implants) and establishes Operational Relay Box (ORB) infrastructure that can be used by other China-aligned threat actors. The report is campaign-level and does not enumerate a single named victim breach event date.

•[ cyber espionage, phishing, Shadow Campaigns ]
BleepingComputer summarized Unit 42 research on a state-aligned espionage group tracked as TGR-STA-1030/UNC6619 conducting global operations dubbed Shadow Campaigns. The report said the actor compromised at least 70 government and critical infrastructure organizations across 37 countries and conducted reconnaissance activity targeting government entities connected to 155 countries during NovDec 2025. The article describes initial access via tailored phishing (Mega-hosted archives) and exploitation of multiple known vulnerabilities, use of webshells and tunneling tools, and a custom Linux eBPF rootkit (ShadowGuard)

•[ espionage, phishing, vulnerability exploitation ]
BleepingComputer summarized Unit 42 research on a state-aligned espionage group tracked as TGR-STA-1030/UNC6619 conducting global operations dubbed Shadow Campaigns. The report said the actor compromised at least 70 government and critical infrastructure organizations across 37 countries and conducted reconnaissance activity targeting government entities connected to 155 countries during NovDec 2025. The article describes initial access via tailored phishing (Mega-hosted archives) and exploitation of multiple known vulnerabilities, use of webshells and tunneling tools, and a custom Linux eBPF rootkit (ShadowGuard), but it does not provide a single discrete victim organization record with a specific primary effect suitable for one CED event entry.
Two undisclosed government departments in a South American country
October 22, 2025
•[ vulnerability exploitation, espionage, data leak ]
Actors exploited a patched SharePoint ToolShell flaw to gain initial access at a telecom, harvest credentials, and pivot across AD-joined systems. Activity included beaconing and data staging consistent with telecom espionage. No operational shutdown reported; primary effect is unauthorized access and data collection.
Kansas City National Security Campus network
October 1, 2025
•[ vulnerability exploitation, espionage, nation-state actor ]
CSO reports KCNSC (NNSA nuclear components plant) was infiltrated via unpatched on-prem SharePoint. Microsoft tied the wider wave to China-linked actors, while a KCNSC source suggested a Russian group; DOE later said the department was minimally impacted. Primary effect: covert access/collection, not OT disruption.
At least one organization in Southeast Asia
October 1, 2025
•[ espionage, APT activity, vulnerability exploitation ]
BleepingComputer summarized Check Point research on a newly tracked actor Amaranth Dragon, linked to China-aligned APT activity, which exploited WinRAR CVE-2025-8088 in espionage operations against government and law enforcement entities in Singapore, Thailand, Indonesia, Cambodia, Laos, and the Philippines. The actor used geofenced infrastructure and a custom loader to deliver encrypted payloads (including Havoc and a newer TGAmaranth RAT using Telegram for C2). Because the article is campaign/threat-research reporting without a discrete, named victim event record and bounded impacts, event_type and event_subtype are coded as NA for CED incident purposes.

•[ vulnerability exploitation, data leak, third-party breach ]
A cybercrime group exploited a URL redirection vulnerability in a third-party contractor system for StubHub to steal around 1,000 digital tickets for major events, including Taylor Swifts Eras Tour. The stolen tickets, valued at approximately $635,000, were resold online for profit. The scheme operated between June 2022 and July 2023 before being uncovered through a coordinated investigation by cybersecurity and law enforcement agencies. Two individuals, Tyrone Rose and Shamara P. Simmons, were arrested and charged with grand larceny, identity theft, and computer tampering in connection with the operation.
