🦊 Silver Fox has resumed targeted spearphishing against Japanese companies during the annual tax and personnel change season. Attackers send tailored, believable HR and tax-themed emails and spoof trusted employees to deliver malicious attachments or links that drop ValleyRAT. Because recipients expect such communications, these lures increase the risk of compromise. Verify suspicious requests through alternate channels and report them to security teams immediately.

🔔 Unit 42 reports a targeted phishing campaign where attackers impersonate Palo Alto Networks talent acquisition staff to lure senior professionals. Adversaries use scraped LinkedIn data, company logos, and look-alike email domains to claim candidates’ resumes fail applicant tracking systems and pressure them into paid 'ATS alignment' services. Recipients are advised to verify sender domains, refuse payment requests, avoid suspicious attachments, and report incidents to corporate security and Unit 42 for assistance.

🦊 Sekoia has identified a series of Silver Fox campaigns from 2025–2026 that blend espionage and financially motivated cybercrime. Attackers used tax- and payroll-themed phishing lures, SEO poisoning and malicious ads to deliver tools such as ValleyRAT, HoldingHands and a custom Python credential stealer disguised as a WhatsApp app. Targets included organizations across Taiwan, Japan and multiple Southeast Asian countries. Researchers say the group’s modular approach enables rapid tool changes while preserving persistence in compromised networks.

⚠️ South Korean firm Genians links a multi-stage intrusion to the North Korean-affiliated Konni group, which used spear-phishing ZIP attachments containing malicious .LNK shortcuts to deploy an AutoIt remote-access trojan, EndRAT. The shortcut fetches a next-stage payload, establishes persistence via scheduled tasks, and displays a PDF decoy while the malware stealthily exfiltrates documents. Investigators found additional AutoIt artifacts for RftRAT and RemcosRAT, and the attacker abused the victim's KakaoTalk desktop to send infected ZIP files to selected contacts, turning compromised systems into propagation hubs.

🛡️ 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.

🐾 ClearSky researchers uncovered a multi-stage malware campaign named BadPaw that leverages emails from the Ukrainian provider ukr.net to lure recipients to a ZIP download. The archive contains an HTA disguised as HTML that displays a decoy document while launching hidden components. BadPaw checks system age to evade sandboxes, extracts payloads, and uses a scheduled task plus steganography to persist. A staged C2 flow ultimately deploys a multi-layered backdoor, MeowMeowProgram.exe, with low AV detection.

🚨 Researchers at CloudSEK have uncovered a mobile espionage campaign, dubbed RedAlert, that distributes a trojanized version of Israel's official Red Alert rocket warning app via SMS phishing and sideloaded fake updates. The malicious build imitates the genuine interface and continues to deliver real alerts while running a covert surveillance payload that requests high-risk permissions such as SMS access, contacts and precise GPS. It uses advanced anti-detection techniques — including spoofing the original signing certificate, falsifying Play Store installation metadata and manipulating Android's package manager via reflection and proxy hooks — to hide secondary payloads and avoid integrity checks. Incident response guidance recommends isolating affected devices, revoking privileges, performing factory resets when necessary, and blocking known domains while restricting sideloading through mobile device management.

🔎 Zscaler ThreatLabz detected a January 2026 campaign by an Iran-nexus actor tracked as Dust Specter that impersonated Iraq’s Ministry of Foreign Affairs and used compromised government infrastructure to host and distribute payloads. The operation deployed previously undocumented tooling — SplitDrop, TwinTask, TwinTalk — and a consolidated .NET RAT called GhostForm. Researchers observed emoji and unicode artifacts in decompiled code that strongly suggest generative AI assisted in development.

🛡️Arctic Wolf reports SloppyLemming operated from January 2025 to January 2026, targeting government and critical infrastructure organizations in Pakistan and Bangladesh. The actor used spear‑phishing PDFs and macro‑enabled Excel files to deliver two distinct toolchains: a DLL side‑loading path that deploys an in‑memory backdoor and a Rust‑based keylogger. The side‑loading route leverages ClickOnce manifests to drop a legitimate .NET binary (NGenTask.exe) and a malicious loader (mscorsvc.dll) that decrypts and runs the implant BurrowShell. The keylogger includes port scanning and network enumeration capabilities and the campaign abused Cloudflare Workers domains and Havoc/Cobalt Strike tradecraft.

⚠️ Researchers report a new phishing campaign in which North Korean hackers pose as company recruiters and lure developer job candidates with seemingly legitimate coding challenges. When victims run the supplied code, it installs malware on their machines, creating a direct avenue for compromise. Reversing Labs analyzed the samples and BleepingComputer provided additional reporting. Candidates and employers should be cautious about running unvetted code and verify recruiter identities.

🔍 This Fortinet analysis dissects a recent multi-stage campaign deploying Agent Tesla, which targets Windows users with credential theft and keylogging. The chain uses spearphishing with RAR attachments containing obfuscated JSE loaders that fetch encrypted PowerShell scripts and reflectively load .NET assemblies in memory. Operators leverage process hollowing, virtualization and sandbox checks, and SMTP-based exfiltration to minimize detection. Fortinet telemetry and cross-product protections are highlighted to help organizations mitigate the threat.

🛡️ Microsoft warns that a coordinated campaign is using job-themed repositories—often posing as Next.js projects or technical assessments—to infect developer systems with multi-stage backdoors. Attackers embed workspace automation, build scripts, or server startup hooks so simply opening or building a project can load remote JavaScript and execute in memory. Microsoft advises containing affected endpoints, tracing process trees, hunting for repeated polling to attacker infrastructure, enforcing VS Code Workspace Trust, applying attack surface reduction, enabling cloud reputation checks, and tightening developer trust boundaries.

📧 A financially motivated threat group dubbed Diesel Vortex has run an extensive phishing campaign since September 2025 targeting freight and logistics operators across the U.S. and Europe, using roughly 52 domains to harvest credentials. Researchers at Have I Been Squatted and partner Ctrl-Alt-Intel discovered exposed repositories and Telegram webhook logs revealing the group's tooling, communications, and an internal mind map describing a call-center style operation. The campaign stole 1,649 unique credential pairs and employed sophisticated evasion — Cyrillic homoglyphs, a nine-stage cloaking chain, voice phishing, Telegram infiltration, and pixel-perfect clones — before coordinated takedowns disrupted the infrastructure.

🔒 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.

🔎 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.

⚠️FortiGuard Labs observed targeted phishing campaigns in Taiwan delivering Winos 4.0 (ValleyRat) and modular plugins via weaponized attachments and cloud-hosted links. Lures impersonate tax audits, e-invoice portals, and installer packages to trick recipients. Attackers employ rotating domains, malicious LNK files, DLL sideloading, and BYOVD using the vulnerable driver wsftprm.sys to gain kernel privileges and evade defenses. Fortinet detections include W64/Agent.ATW!tr and multiple email and gateway protections.

🔐 Pakistan-aligned clusters APT36 and SideCopy are targeting Indian defense and government organizations to deploy cross-platform remote access trojans on Windows and Linux. Attack chains use phishing lures that deliver malicious LNK/HTA files, ELF binaries, and PowerPoint Add-In payloads to initiate multi-stage deployments. Observed malware — Geta RAT, Ares RAT, and DeskRAT — enables persistence, reconnaissance, data theft, and remote command execution while leveraging decoys and memory-resident techniques to evade detection.

📱 ZeroDayRAT is a newly documented cross-platform mobile spyware operation targeting Android and iOS, according to iVerify. The toolkit grants persistent access to messages, precise GPS history, notifications, camera, microphone and keystroke capture, and exposes a dedicated web dashboard for rapid device profiling. Infections are commonly initiated via smishing, counterfeit app stores, phishing emails and links shared through messaging apps.

🔒 Several European government bodies reported breaches tied to a coordinated exploitation of Ivanti EPMM zero-day vulnerabilities disclosed on 29 January. Affected organizations include the European Commission, Finnish central agencies and at least two Dutch bodies, with as many as 50,000 Finnish staff details potentially exposed. Compromised data appears limited to names, work emails, phone numbers and device metadata; no device-level data has been confirmed. Authorities contained the incidents quickly, but security teams warn of elevated follow-on risks such as spearphishing, credential misuse and malicious configuration changes, and advise reassessing administrative credentials, keys and certificates.

🔒 Mandiant links a targeted intrusion to UNC1069 that leveraged AI-enabled social engineering to compromise a cryptocurrency executive and deploy multiple macOS malware families. The attacker used a hijacked Telegram account, a spoofed Zoom meeting allegedly featuring a deepfake video, and a ClickFix paste-and-execute ruse to trick the victim into running troubleshooting commands. The operation dropped WAVESHAPER, HYPERCALL, HIDDENCALL, SUGARLOADER, DEEPBREATH, CHROMEPUSH, and SILENCELIFT to harvest credentials, browser data, and session tokens. GTIG and Mandiant highlight UNC1069's expanding use of GenAI for lures and tooling.
