🔐 Die Linke says it was hit by a serious cyberattack that it attributes to the hacker group Qilin, possibly Russian‑speaking, and has taken parts of its IT infrastructure offline. Party federal secretary Janis Ehling said attackers appear to be seeking sensitive internal and employee data; the membership database was not compromised. Authorities warned the party as the intrusion was detected, and a criminal complaint has been filed as the party coordinates with security services.

🔒 Aleksei Olegovich Volkov, a 26-year-old Russian national, was sentenced in the U.S. to 81 months in prison after pleading guilty to facilitating dozens of ransomware attacks as an initial access broker. Authorities say he helped breach networks and sell access to ransomware groups, resulting in over $9 million in actual losses and more than $24 million in intended losses. He was arrested in Italy in January 2024, extradited to the U.S., and agreed to pay restitution and forfeit tools used in the crimes.

🔒 U.S. agencies warn that threat actors aligned with Russian intelligence are conducting targeted social-engineering phishing campaigns to compromise commercial messaging apps such as Signal and WhatsApp. The attacks have led to unauthorized access to thousands of accounts and involve impersonation of support personnel to request SMS codes, verification PINs, or to deliver malicious QR links. Victims who provide codes can lose account control, while those who scan attacker-controlled QR codes may have past and future messages exposed. Authorities advise never sharing verification codes and regularly reviewing linked devices in app settings.

🔔 The FBI has publicly attributed widespread phishing campaigns against encrypted messaging apps—primarily Signal and, to a lesser extent, WhatsApp—to actors linked to Russian intelligence services. The adversaries do not break end-to-end encryption; they hijack accounts via social engineering, commonly tricking victims into sharing verification codes or scanning malicious QR codes. Thousands of accounts worldwide have reportedly been compromised, often targeting individuals with sensitive access. Authorities urge users to refuse unsolicited device-linking requests and never share verification codes.

🔒 CISA and the Federal Bureau of Investigation issued a joint Public Service Announcement warning of ongoing phishing campaigns by cyber actors associated with Russian intelligence services targeting commercial messaging applications (CMAs). The campaigns seek to bypass encryption by compromising individual user accounts rather than breaking application cryptography. Evidence indicates thousands of CMA accounts have been accessed to view messages and contact lists, send messages, and conduct follow-on phishing. CISA and FBI urge users to review the PSA, adopt recommended cybersecurity practices, and remain vigilant for suspicious activity.

🔍 Aryaka Threat Research Lab has identified a campaign that distributes resume-like attachments to target HR and recruiting staff, deploying a component named BlackSanta that attempts to disable endpoint detection and response. The multi-stage infection chain performs system reconnaissance, sandbox and VM checks, and geographic and language filtering before downloading further payloads. Attackers appear Russian-speaking and leverage routine hiring workflows to increase success, while encrypted communications and data exfiltration help maintain persistence.

🛡️ Researchers at Aryaka uncovered a Russian-speaking threat actor using targeted spear-phishing emails that delivered ISO attachments masquerading as resumes to deploy a new EDR-killing module named BlackSanta. The multi-stage infection leverages a malicious .LNK to launch a PowerShell script that extracts hidden code via steganography and runs payloads in memory. The chain also uses DLL sideloading with a legitimate SumatraPDF executable and a malicious DWrite.dll, and performs extensive fingerprinting and environment checks to evade sandboxes. BlackSanta disables and terminates security tooling, adjusts Microsoft Defender settings and suppresses notifications to minimize user alerts.

🛡️ X told British MPs it suspended 800 million accounts in 2024 for breaching rules on platform manipulation and spam. Company government affairs executive Wifredo Fernández said Russia was the most active state-backed manipulator, followed by Iran and China, and that efforts to influence elections and 'flood the zone' persist. Despite Elon Musk's prior pledge to purge bots, X acknowledges hundreds of millions of inauthentic accounts are removed annually, raising concerns about uncaught actors and moderation practices.

🔒 Dutch intelligence has uncovered a large-scale campaign by Russian state actors to hijack Signal and WhatsApp accounts belonging to military, government and other high-value individuals worldwide. The attackers impersonate support bots, request SMS verification codes or PINs, and exploit linked-device QR flows to add devices. Authorities warn these consumer apps, while end-to-end encrypted, are unsuitable for classified material and have issued guidance to detect and remediate account takeovers.

🐾 ClearSky reports a Russian-linked campaign targeting Ukrainian entities that deploys a .NET loader named BadPaw and a backdoor called MeowMeow. The attack begins with a phishing message that lures victims to download a ZIP archive containing an HTA decoy presenting a Ukrainian border-crossing appeal while executing hidden stages. The HTA extracts a VBScript and a PNG-embedded loader, establishes persistence via a scheduled task, and orchestrates retrieval of the MeowMeow backdoor from a remote C2 server. Researchers attribute the operation to APT28 with moderate confidence based on targeting, lures, and tradecraft overlaps.

🚨 Security researchers say an open-source, AI-native offensive platform called CyberStrikeAI was used to automate mass scanning and exploitation of Fortinet FortiGate appliances, contributing to compromises of more than 600 devices across 55 countries. Team Cymru traced activity to a Russian-speaking actor after analyzing an IP address and observed 21 unique IPs running the tool between January 20 and February 26, 2026. The tool's GitHub maintainer, known as Ed1s0nZ, has published a range of exploitation and AI-jailbreak utilities and shows interactions with organizations linked to Chinese state cyber capabilities.

🔍 Akamai links the Russia-linked actor APT28 to exploitation of CVE-2026-21513, a high-severity (CVSS 8.8) MSHTML security feature bypass that Microsoft patched in its February 2026 update. The flaw in ieframe.dll mishandles hyperlink navigation and can be weaponized by malicious HTML or LNK files to invoke ShellExecuteExW and run resources outside the browser sandbox. Akamai identified a sample uploaded to VirusTotal on 30 January 2026 tied to infrastructure associated with APT28, while Microsoft and Google intelligence teams reported real-world exploitation.

🔒 The U.S. Treasury Department's Office of Foreign Assets Control designated Matrix LLC (doing business as Operation Zero) and its owner, Sergey Zelenyuk, under the Protecting American Intellectual Property Act, marking the first use of that law. The move coincided with the sentencing of former L3Harris manager Peter Williams, who was given 87 months for stealing eight zero‑day exploits and selling them to Operation Zero for about $1.3 million in cryptocurrency. OFAC also named related companies and individuals, including a UAE front company and a suspected Trickbot affiliate, freezing U.S. assets and warning of potential secondary sanctions for U.S. persons who transact with the designated parties.

🔒 Peter Williams, former head of Trenchant at L3Harris, was sentenced to 87 months in federal prison after admitting he stole and sold zero-day exploit components to the Russian broker Operation Zero. Prosecutors say he transferred at least eight protected exploit components between 2022 and 2025 using a portable external drive and encrypted channels. L3Harris estimates the theft caused $35 million in losses and the sales netted Williams $1.3 million in cryptocurrency. Authorities ordered forfeiture of the crypto, a house, and luxury items, and the U.S. Treasury announced sanctions against the broker.

🔒 A Russia-aligned cybercrime cluster tracked as UAC-0050 (also known as DaVinci Group and labeled Mercenary Akula by BlueVoyant) carried out a spear-phishing operation this month against a European financial institution involved in regional development and reconstruction. The campaign spoofed a Ukrainian judicial domain and lured a senior legal and policy advisor to download an archive hosted on PixelDrain, which unpacked into a password-protected chain culminating in an executable disguised as a PDF. Execution led to installation of an MSI that deployed RMS remote desktop software, providing persistent remote control and file-transfer capabilities, consistent with the group’s prior use of remote-access tools to evade detection and maintain stealthy access.

🤖 Amazon Threat Intelligence says a Russian-speaking actor used commercial generative AI services to compromise hundreds of FortiGate firewalls by exploiting exposed management interfaces and weak, single-factor credentials. Between Jan. 11 and Feb. 18 the group breached over 600 devices across 55+ countries, then accessed Active Directory, extracted credential databases, and targeted backups. Amazon recommends fundamental controls — restrict management access, enforce MFA, patch perimeter devices, improve segmentation, and enhance detection — noting the attacker’s toolkit and operational plans were largely AI-generated and publicly left on infrastructure used in the campaign.

🔎 S2 Grupo's LAB52 attributes a campaign codenamed Operation MacroMaze to the Russia-linked APT28, active from September 2025 through January 2026. The attackers used spear-phishing documents containing an INCLUDEPICTURE field that points to webhook[.]site URLs to confirm document opens and deploy macros that run VBScript and batch files. Payloads render Base64 HTML in Microsoft Edge, using headless or off-screen browsers to retrieve commands and exfiltrate output to webhook endpoints. LAB52 emphasizes the campaign's operational simplicity and reliance on legitimate services to reduce detection.

🔍 Amazon Web Services reported a low-skilled, Russian-speaking actor used commercial GenAI services to run an opportunistic campaign that compromised over 600 FortiGate devices across more than 55 countries between 11 January and 18 February 2026. The attacker scanned internet-exposed management interfaces, attempted commonly reused credentials and relied on AI-assisted scripts to parse stolen configurations and automate VPN access. AWS noted no exploitation of FortiGate vulnerabilities and that AWS infrastructure was not involved. Defenders are urged to prioritize patching, credential hygiene and post-exploitation detection.

⚠️ Google Threat Intelligence Group (GTIG) attributes a previously undocumented actor, likely linked to Russian intelligence, to campaigns using CANFAIL against Ukrainian defense, military, government, and energy organizations. The actor has expanded interest to aerospace, defense-adjacent manufacturing, nuclear and chemical research, and humanitarian groups, often impersonating Ukrainian and Romanian energy firms in phishing. Operators used LLMs to produce reconnaissance and social-engineering lures, embedding Google Drive links to RAR archives that deliver obfuscated JavaScript which spawns PowerShell memory-only droppers. GTIG links this activity to the PhantomCaptcha campaign disclosed by SentinelOne SentinelLABS in October 2025.

🛡️ Google Threat Intelligence Group warns state-backed actors are abusing Gemini across the full attack lifecycle, from reconnaissance and phishing-lure generation to C2 development and data exfiltration. Groups linked to China, Iran, North Korea, and Russia used the model for target profiling, code generation, translation, vulnerability testing, and troubleshooting. Google says it has disabled abusive accounts and implemented targeted classifier defenses to make misuse harder.
