🔒 Recorded Future links GRU-affiliated APT28 (aka BlueDelta) to targeted credential-harvesting campaigns in 2025 that hit staff at a Turkish energy and nuclear research agency, a European think tank, and entities in North Macedonia and Uzbekistan. The group used regionally tailored Turkish-language lures and legitimate PDF decoys, deployed spoofed OWA, Google and Sophos VPN pages hosted on services such as Webhook.site, InfinityFree, Byet and ngrok, exfiltrating credentials before redirecting victims to real sites to avoid detection.

📲 Russian-aligned threat actor UAC-0184 used the Viber messaging app to deliver malicious ZIP archives to Ukrainian military and government recipients, according to 360 Threat Intelligence Center. The archives contained LNK decoys that silently executed Hijack Loader, which retrieves a second ZIP (smoothieks.zip) via PowerShell and reconstructs the loader in memory. The loader uses DLL side-loading, module stomping, CRC32 checks for installed security products, and scheduled tasks for persistence before injecting Remcos RAT into chime.exe to enable remote control and data theft.

🔒 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.

🔒 Proofpoint links a September 2025 phishing campaign to a suspected Russia-aligned cluster called UNK_AcademicFlare that exploits device code authentication to seize Microsoft 365 accounts. The group leverages compromised government and military email addresses to build rapport and send Cloudflare Worker links that mimic OneDrive, asking victims to copy and enter a short code. When users input the code on Microsoft's device code page, the service issues an access token that attackers can capture to take over accounts.

🛡️ The Danish Defence Intelligence Service (DDIS) said on December 18, 2025 that Russian-aligned actors were responsible for recent destructive and disruptive cyber activity against Denmark. The agency named pro‑Russian hacktivist groups Z‑Pentest for a destructive 2024 intrusion at a water utility and NoName057(16) for DDoS campaigns targeting websites ahead of the 2025 municipal and regional elections. DDIS assessed both groups have links to the Russian state and are being used as instruments of a hybrid campaign to create insecurity and penalise countries supporting Ukraine. The statement followed a global advisory, co-signed by 23 law enforcement and intelligence bodies, which catalogued related TTPs.

🔒 Danish intelligence (DDIS) attributed a destructive cyberattack on a water utility to Russian-linked actors, identifying Z-Pentest as responsible for the sabotage and NoName057(16) for election-period DDoS operations. The agency said these actions are part of Moscow's broader hybrid campaign to punish countries supporting Ukraine. Officials will summon the Russian ambassador and warned the attacks undermine public security.

🛡️The Greens say recent findings of Russian influence operations during the federal election confirm that existing protections for parliamentary democracy are inadequate. Although Germany implemented the NIS-2 law on December 6, 2024, it covers the federal administration and Bundestag administration but not the Bundestag as an institution or MPs' constituency offices. The federal government attributes an August 2024 cyberattack on air traffic control to the GRU-linked group Fancy Bear and says the campaign "Storm 1516" targeted the election with disinformation; the Russian ambassador was summoned.

🔎 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.

🔐 Amazon Threat Intelligence details a multi-year, state-sponsored Russian campaign—assessed as GRU-linked—that targeted Western critical infrastructure, especially the energy sector, from 2021 through 2025. The actor shifted from exploiting N-day/zero-day flaws to abusing misconfigured customer network edge devices (including EC2-hosted appliances) to intercept credentials and gain persistent access. Amazon observed packet-capture based credential harvesting and subsequent credential replay attempts, with infrastructure overlaps linked to clusters tracked as Curly COMrades and Sandworm. Recommended mitigations include auditing edge devices, enforcing strong authentication, monitoring for credential replay, and applying AWS-specific controls.

🔓 VolkLocker, a new RaaS from the pro‑Russian group CyberVolk (GLORIAMIST), contains a critical implementation flaw that lets victims recover files without paying. Test samples embed a master key and write it in plaintext to the %TEMP% folder (system_backup.key), while using that same key for AES‑256‑GCM encryption. The Golang-built strain targets Windows and Linux, modifies the registry, deletes shadow copies, and uses Telegram automation for command-and-control and victim management.

⚠️ This joint advisory from CISA, FBI, NSA, and international partners details opportunistic intrusions by pro‑Russia hacktivist groups—CARR, NoName057(16), Z‑Pentest, and Sector16—against OT/ICS environments. Actors are exploiting internet‑exposed VNC services, using open‑source scanning and brute‑force tools to access HMI devices with default or weak credentials, causing loss of view, configuration changes, and operational downtime. The advisory urges organizations to reduce public exposure, apply network segmentation, enforce strong authentication (MFA where feasible), harden device credentials, and follow secure‑by‑design guidance for OT products.

📧 Sekoia.io researchers have identified a fresh wave of spear-phishing linked to the Russia-nexus intrusion set Star Blizzard (aka Calisto/ColdRiver) that targeted NGOs including Reporters Without Borders in May–June 2025. Operators impersonated trusted contacts via ProtonMail, using a custom Adversary-in-the-Middle kit to harvest credentials and relay 2FA prompts through compromised sites and redirectors. Observed tactics included a ZIP disguised as a .pdf, decoy encrypted PDFs instructing victims to open files in ProtonDrive, injected JavaScript to lock password-field focus, and an API-driven workflow for handling CAPTCHA and 2FA challenges, underscoring continued risk to Western organizations supporting Ukraine.

🔒 Arctic Wolf Labs observed a targeted September 2025 campaign in which the Russia-aligned RomCom group used fake browser-update prompts to deliver the Mythic Agent implant via a classic SocGholish chain. Researchers say this is the first observed instance of RomCom pairing SocGholish initial access with a Mythic C2-based loader. The intrusion was stopped before impact, and Arctic Wolf published IOCs and mitigation guidance.

🔒 Arctic Wolf Labs reports that a RomCom payload was delivered via a JavaScript loader known as SocGholish to a U.S.-based civil engineering company, marking the first observed use of this distribution method. The chain relied on fake browser update prompts to run a loader that established a reverse shell, dropped a custom Python backdoor called VIPERTUNNEL, and installed a RomCom DLL loader that launched the Mythic Agent. Attribution to GRU Unit 29155 is assessed at medium-to-high confidence, and the intrusion was blocked before it could progress further.

💳 A Russian-speaking threat actor has registered more than 4,300 domains since early 2025 to host convincing fake travel and hotel booking pages that harvest payment card data. According to Netcraft researcher Andrew Brandt, the campaign—active since February—uses a customizable phishing kit that serves branded pages for platforms like Booking, Expedia, and Airbnb and supports 43 languages. The kit requires a unique AD_CODE in the URL to render targeted branding (otherwise visitors see a blank page), employs fake Cloudflare-style CAPTCHA, and persists state in a cookie so subsequent pages maintain consistent impersonation. Victims are prompted to pay a deposit; entered card numbers, expiry and CVV are processed in the background while a bogus support chat guides users through a sham 3D Secure step to complete the theft.

🔍 The ESET research team released its APT Activity Report covering April–September 2025, summarizing operations by state-aligned hacking groups. The report details espionage, disruptive attacks and monetized campaigns targeting government and corporate networks across multiple regions. Notably, the Russia-aligned group Sandworm deployed several data wipers against Ukraine's grain sector, an apparent attempt to harm economic resilience. ESET Chief Security Evangelist Tony Anscombe outlines key findings in an accompanying video and encourages readers to consult the full report for technical specifics.

🛡️ ESET's APT Activity Report covering Q2–Q3 2025 reports that Russian-aligned Sandworm deployed new data wipers, identified as Zerolot and Sting, against Ukrainian targets including government bodies and critical sectors such as energy, logistics and grain. The firm assessed the activity as likely intended to weaken Ukraine's economy. The findings, published on 6 November 2025, also note increased espionage and tool-sharing among other Russia-aligned groups.

🛡️ Bitdefender researchers describe how the Russia-aligned APT group Curly COMrades enabled Windows Hyper-V to deploy a minimal Alpine Linux VM on compromised Windows 10 hosts, creating a hidden execution environment. The compact VM (≈120MB disk, 256MB RAM) hosted two libcurl-based implants, CurlyShell (reverse shell) and CurlCat (HTTP-to-SSH proxy), enabling C2 and tunneling that evaded many host EDRs. Attackers used DISM and PowerShell to enable and run the VM under the deceptive name "WSL," and also employed PowerShell and Group Policy for credential operations and Kerberos ticket injection. Bitdefender warns that VM isolation can bypass EDR and recommends layered defenses including host network inspection and proactive hardening.

🛡️The Russian-linked threat group Curly COMrades abused Microsoft Hyper-V on Windows hosts to deploy a hidden, minimal Alpine Linux VM that hosted custom implants: CurlyShell (reverse shell) and CurlCat (reverse proxy). By using the Hyper-V Default Switch and naming the VM "WSL," outbound C2 traffic appeared to originate from the legitimate host IP, enabling evasion of host-based EDRs. The campaign — active since mid-2024 and observed by Bitdefender with help from the Georgian CERT — also employed PowerShell scripts for LSASS Kerberos ticket injection and Group Policy-based account creation, leaving few forensic traces. Organizations are advised to monitor unexpected Hyper-V activation, abnormal LSASS access or tampering, PowerShell GPO deployments, and to implement network-level inspection and layered defenses.

🔒 Russian authorities have arrested three individuals in Moscow accused of creating and operating the Meduza information‑stealing malware. Announced on Telegram by police general Irina Volk, investigators say the group developed and distributed Meduza via hacker forums around two years ago and offered it as a subscription-based service. The tool steals browser-stored credentials and cryptocurrency data and, since December 2023, can resurrect expired Chrome authentication cookies to facilitate account takeover. Authorities opened a criminal case after operators targeted an Astrakhan institution and seized confidential server data.
