Multi-stage phishing and supply-chain malware campaigns targeting credentials and long-term access
Multiple reports highlight active campaigns using phishing and software supply-chain abuse to steal credentials and establish persistence. eSentire described an espionage-focused operation targeting residents of India with emails impersonating the Income Tax Department, leading victims to a malicious archive that uses DLL side-loading with a legitimate signed Microsoft application, extensive anti-analysis checks, in-memory shellcode unpacking, UAC bypass, and process masquerading; the payload was identified as a Blackmoon-family variant that specifically attempts to disable Avast Free Antivirus by automating UI interactions to add exclusions. Separately, Aikido reported a malicious npm package (ansi-universal-ui) that deploys a multi-stage infostealer (“G_Wagon”) by abusing postinstall execution, downloading a Python runtime, running an obfuscated payload, and exfiltrating browser credentials, cloud credentials, Discord tokens, and data from 100+ cryptocurrency wallets to an Appwrite storage bucket; it also includes a Windows DLL used for browser-process injection via NT native APIs.
In parallel, network-edge exploitation remains a key access vector: Risky Business reported a renewed wave of attacks against Fortinet FortiGate devices via a vulnerability Fortinet allegedly “patched” in December but which attackers can still exploit, enabling SSO authentication bypass (via crafted SAML), creation of new admin accounts, and theft of device configuration; mitigations include disabling the FortiCloud SSO feature (not enabled by default). Several other items are general awareness or roundup content rather than specific incident reporting: TechTarget and other blogs emphasized ongoing phishing/email risk (including relay spam abusing legitimate Zendesk instances) and password hygiene, while The Hacker News published a multi-story bulletin that includes (among other items) a spear-phishing campaign in Afghanistan delivering a FALSECUB backdoor via a GitHub-hosted ISO and LNK execution chain; Risky Business also covered Iran’s internet blackout and Starlink jamming/spoofing as a communications-control issue rather than an enterprise cyber incident.

Security Research Roundup: Supply-Chain Malware, Phishing Operations, and Evolving Social Engineering
Multiple security reports and investigations highlighted active threats spanning software supply chain abuse, phishing operations, and commodity malware delivery. Socket identified **four malicious NuGet packages** (e.g., *NCryptYo*, *DOMOAuth2_*, *IRAOAuth2.0*, *SimpleWriter_*) published by `hamzazaheer` that targeted **ASP.NET** developers by exfiltrating ASP.NET Identity data (users/roles/permissions) and manipulating authorization to maintain persistence; the campaign used a staged loader that set up a local proxy on `localhost:7152` to relay traffic to dynamically resolved C2 infrastructure. Separately, investigators disrupted a logistics-focused **phishing-as-a-service** operation (“**Diesel Vortex**”) tied to Russian/Armenian operators, which used dozens of domains to target users of platforms such as **DAT**, **Truckstop**, **Penske Logistics**, **EFS**, and **Timocom**, resulting in theft of over **1,600 credentials** and attempted **EFS check fraud**. Fortinet also detailed a **multi-stage Agent Tesla** infection chain delivered via phishing with RAR attachments leading to `.jse` and PowerShell stages, culminating in in-memory execution and process hollowing into `C:\Windows\Microsoft.NET\Framework\v4.0.30319\Aspnet_compiler.exe`. Threat intelligence and ecosystem reporting also underscored how attackers are scaling operations and bypassing traditional controls. Group-IB reported **MuddyWater** (“Operation Olalampo”) targeting the **MENA** region with new tooling including **GhostFetch** and a Rust backdoor (**CHAR**) controlled via **Telegram**, plus variants that deploy **AnyDesk**; the report noted indicators consistent with **AI-assisted development**. Dark Reading described the rise of **telephone-oriented attack delivery (TOAD)** emails—messages containing only a phone number—which accounted for a significant share of gateway-bypassing detections in StrongestLayer’s dataset, reflecting a shift toward social-engineering paths that evade link/attachment scanning. Confiant reported disrupting **D-Shortiez** malvertising operations after discovering exposed internal testing/admin infrastructure, attributing **59 million** malicious ad impressions (primarily US-targeted) to scam campaigns, while Interpol-backed **Operation Red Card 2.0** reported **651 arrests** and **$4.3M** recovered across 16 African countries in actions against fraud rings and cybercrime syndicates.

Social Engineering and Phishing-Driven Intrusions Targeting Identity and Remote Access
Multiple reports highlight **social engineering and phishing** as primary initial-access vectors, with attackers increasingly targeting **identity systems** rather than exploiting software vulnerabilities. Microsoft was again the most spoofed brand in phishing during Q4 2025 (22% of observed brand-impersonation attempts), reflecting how attackers abuse trust in major identity and productivity platforms to harvest credentials; examples cited include lures mimicking Netflix account recovery, Roblox-related pages, and Spanish-language Facebook scams. Separately, an incident response case described payroll fraud achieved without malware or a network breach: an attacker impersonated employees to help desks, reset passwords, re-enrolled MFA, and registered an external email as an authentication method in **Azure Active Directory**, then altered direct-deposit details to redirect paychecks—underscoring how **help-desk processes and MFA reset workflows** can be exploited for persistence and financial theft. Targeted campaigns also show continued evolution in delivery tradecraft for **remote access**. A spear-phishing operation against Argentina’s judicial sector used ZIP attachments containing a weaponized Windows shortcut (`.lnk`) masquerading as a PDF plus scripts and a decoy court document to deploy a **Remote Access Trojan** while minimizing user suspicion. In parallel, research described **Pulsar RAT** (a Quasar RAT derivative) emphasizing stealth via **memory-only execution** and **HVNC**, with TLS-encrypted C2 and configuration retrieval from public paste sites, alongside persistence mechanisms such as scheduled tasks and UAC-bypass techniques. Another campaign attributed to **Konni APT** (“Operation Poseidon”) abused **Google and Naver ad redirection** (e.g., `ad.doubleclick[.]net`, `mkt.naver[.]com`) to launder clicks through trusted ad infrastructure before landing victims on compromised sites hosting malware, demonstrating how open-redirect and ad-tech trust can bypass reputation-based controls.

Multiple APT and malware campaigns abusing phishing, cloud services, and signed binaries
Reporting across multiple research teams described a surge of distinct, ongoing intrusion campaigns rather than a single unified incident. **Check Point** reported on **Silver Dragon**, a Chinese-aligned activity cluster assessed as operating under the broader **APT41** umbrella, targeting organizations in **Southeast Asia and Europe** (notably government) via exploitation of public-facing servers and phishing, then deploying **Cobalt Strike**, **DNS tunneling**, and a new Google Drive–based backdoor (**GearDoor**) alongside custom tools (**SSHcmd** and **SliverScreen**) for remote access and screen capture. **Microsoft** detailed separate February 2026 phishing campaigns by an unknown actor that used meeting/invoice-style lures and **EV code-signed** malware (certificate issued to **TrustConnect Software PTY LTD**) masquerading as common workplace apps (e.g., `msteams.exe`, `adobereader.exe`, `zoomworkspace.clientsetup.exe`) to install legitimate **RMM** tooling (**ScreenConnect**, **Tactical RMM**, **Mesh Agent**) for persistent access and lateral movement. Other reporting highlighted additional, unrelated campaigns and tradecraft: **ClearSky** described a Russian-aligned operation targeting **Ukraine** using a phishing-delivered ZIP/HTA chain that drops a .NET loader (**BadPaw**) and backdoor (**MeowMeow**) with **.NET Reactor** obfuscation, parameter-gated execution, and sandbox/tooling checks (with low-confidence linkage to **APT28**). **Cofense**-reported activity (via SC Media) showed phishing that weaponizes **Windows File Explorer + WebDAV** using URL/LNK shortcuts to pull payloads (notably **AsyncRAT**, **XWorm**, **DcRAT**) and infrastructure including **Cloudflare Tunnel** domains hosting WebDAV servers. **Cisco Talos**-reported **Dohdoor** activity (UAT-10027) targeted US **education and healthcare**, using PowerShell→batch→DLL sideloading via legitimate executables (e.g., `Fondue.exe`, `mblctr.exe`, `ScreenClippingHost.exe`) and **DNS-over-HTTPS** to Cloudflare for C2 discovery and tunneling. Separately, **Zscaler** reported **ScarCruft**’s *Ruby Jumper* campaign using **Zoho WorkDrive** for C2 and removable media components to reach air-gapped systems, while another Zscaler report analyzed **Dust Specter** targeting Iraqi government officials with password-protected RAR delivery and modular implants. **Qianxin XLab** assessed sanctioned infrastructure provider **Funnull** resurfacing to support scam/criminal supply chains and potential **MacCMS**-related supply-chain activity, and **F5 Labs** summarized **APT42**’s **TAMECAT** PowerShell backdoor focused on Edge/Chrome credential theft with C2 over Telegram/Discord/HTTPS and specific file/hash indicators. (A separate Help Net Security item on a Microsoft Defender onboarding tool is product/administrative news and not part of the threat-campaign reporting.)
