⚠️ A coordinated campaign impersonating Next.js job interview materials uses malicious repositories to achieve remote code execution on developers' machines. Repositories trigger payloads via VS Code workspace opening, npm dev server startup, or backend initialization, downloading and executing an in-memory JavaScript backdoor. The staged malware profiles hosts, registers with a C2 infrastructure, and supports file enumeration and staged exfiltration. Microsoft advises enforcing VS Code Workspace Trust, reducing secrets on endpoints, and using short-lived, least-privilege tokens.

🔒 Google and industry partners disrupted infrastructure used by suspected China-linked espionage group UNC2814, which deployed a C-based backdoor named GRIDTIDE that abuses the Google Sheets API to conceal command-and-control traffic. GRIDTIDE supports file upload/download and arbitrary shell execution and was observed on endpoints containing PII. Google terminated attacker-controlled Cloud projects, disabled abused accounts, and is notifying impacted organizations while offering support.

🔐 Google’s Threat Intelligence Group, Mandiant, and partners disrupted a global espionage campaign attributed to a suspected Chinese actor tracked as UNC2814 that infiltrated telecom firms and government agencies across dozens of countries. The actor deployed a new C-based backdoor named GRIDTIDE that abused the Google Sheets API for covert command-and-control, authenticating with a hardcoded service account key and polling spreadsheet cells for instructions. GRIDTIDE supports execution, upload and download commands via URL-safe Base64 exchanges and hides output in sheet cells; Google and partners disabled cloud projects, revoked API access, sinkholed domains, and offered victim support.

🔒 Security researchers at Socket uncovered four malicious NuGet packages — NCryptYo, DOMOAuth2_, IRAOAuth2.0, and SimpleWriter_ — that target ASP.NET developers to steal Identity data and manipulate authorization rules. The packages, published in August 2024 by user hamzazaheer and downloaded over 4,500 times before removal, deploy a localhost proxy and stage payloads to relay stolen data to an external C2. Separately, Tenable disclosed a malicious npm package ambar-src that used a preinstall hook to drop cross-platform malware (Windows, Linux, macOS), enabling full-system compromise and data exfiltration.

🛡️ 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.

🔒 Malwarebytes researchers warn of a convincing fake Zoom meeting page that silently downloads and installs a covert build of Teramind on Windows endpoints. Victims see scripted participants and an “Update Available” countdown that triggers a silent download while a fake Microsoft Store screen displays a staged installation. Because the payload is a repackaged commercial monitoring tool, many defenses may not flag it, so prompt verification and training are essential.

🔒 This article profiles major ransomware varieties — including crypto, double extortion, encryptionless, locker, scareware and Ransomware-as-a-Service — and explains how they operate. It outlines common detection approaches such as behavioral, signature, heuristic, and deception techniques. The piece also situates ransomware within the broader malware landscape and describes how Huntress’ 24/7 human-led monitoring and containment reduce risk.

⚠️ Microsoft Defender researchers discovered a coordinated developer-targeting campaign that used malicious repositories disguised as legitimate Next.js projects and recruiting assessments to achieve remote code execution. The malicious repositories employed multiple execution paths — editor automation, dev-server assets, and backend startup loaders — that all retrieved attacker-controlled JavaScript at runtime. The activity staged a lightweight registration bootstrap (Stage 1) before escalating to a persistent operator-controlled controller (Stage 2), enabling in-memory tasking, discovery, and staged exfiltration.

⚠️ CrowdStrike's Global Threat Report 2026 warns that AI-enabled cyber-attacks rose 89% in 2025 as adversaries used machine learning and LLMs to scale and refine phishing, disinformation and malware operations. Researchers observed LLMs producing multilingual, convincing phishing lures and automating campaign creation, while some actors embedded prompting into malware (eg, LameHug) for reconnaissance. CrowdStrike recommends strong identity controls, AI-focused awareness training and threat-intel monitoring to mitigate the accelerating threat.

🛡️ CrowdStrike reports that adversaries shifted in 2025 from expanding toolsets to prioritizing evasion, using AI to refine phishing, malware scripts, and reconnaissance while favoring malware-free techniques that blend with legitimate user activity. AI-enabled attacks rose 89% year over year and malware-free methods accounted for 82% of detections. Supply chain compromises, rapid zero-day weaponization, and cloud-focused intrusions amplified stealth, with big-game ransomware groups moving to remote encryption and credential abuse to minimize detection.

🔍 A fraud investigation by the Secuinfra Falcon Team uncovered a layered, Python-based malware deployment that led to unauthorised PayPal transfers and visible command output on the victim's desktop. Investigators found hidden PowerShell activity retrieving a PyInstaller-packed executable named svchoss.exe from an IP hosted in Tencent-associated networks, alongside startup scripts and a concealed Python runtime. Memory forensics with Volatility 3 and string extraction exposed heavy obfuscation, references to Cobalt Strike, XWorm RAT, HTran and attempts to harvest browser autofill and wallet data. Although the system was judged fully compromised, the initial infection vector remains unconfirmed, with social engineering and malicious downloads considered likely.

🛡️ This weekly recap highlights high‑impact incidents and emerging trends across devices, cloud services, and supply chains. Key items include a Dell RecoverPoint zero‑day (CVE‑2026‑22769) actively exploited to install web shells and backdoors and PromptSpy, an Android malware that leverages Google Gemini and accessibility services for persistence. The report also calls out a near‑30 Tbps DDoS surge, malicious Docker Hub images, and deceptive "double‑tap" skimmers targeting e‑commerce. Review the prioritized CVEs and advisories and map mitigations to your environment.

🔍 Kaspersky researchers uncovered a new infostealer named Arkanix that blends rapid, probable LLM-assisted development with a dual-language architecture. The malware is offered as a MaaS, giving customers a control panel to configure Python or C++ payloads and retrieve statistics. The Python variant prioritizes broad, fast data harvesting while the native C++ build focuses on stealth, performance, and persistence. Observed deployment mechanisms include configurable loaders, C2 domains and even Discord-based tests.

🛡️ The FBI reports over 700 ATM jackpotting incidents in 2025 that cost banks more than $20 million, and notes nearly 40% of US attacks since 2020 occurred last year. Attackers commonly deploy malware such as Ploutus to exploit the XFS API, allowing direct hardware commands to dispense cash and bypass bank authorization. The agency details physical intrusion techniques—generic keys, hard-drive removal or replacement with preloaded devices—and urges layered defenses including improved physical locks and sensors, hardware whitelisting, robust logging, IP whitelisting and endpoint detection to detect and prevent rapid cash-outs.

🔒 Group-IB reports that Iranian APT MuddyWater launched Operation Olalampo, using new and updated implants to target organizations across the MENA region. Attacks beginning January 26, 2026 employed malicious Office macros to deliver downloaders like GhostFetch and HTTP_VIP, a Rust backdoor CHAR, and a second-stage implant GhostBackDoor. The campaign leverages C2 servers, a Telegram-controlled bot, and signs of AI-assisted development.

🔐 Cybercriminals increasingly employ generative AI to automate and scale established attack techniques, from highly convincing phishing and deepfakes to AI-assisted malware creation and accelerated vulnerability exploitation. Adversaries are building custom LLMs, hijacking cloud LLM resources, and orchestrating multi-agent campaigns that speed reconnaissance and weaponization. Organizations should adopt layered defenses, monitor API and AI usage, tighten identity and access, and leverage AI-based detection to mitigate these evolving threats.

🔍 Kaspersky researchers analyzed a short-lived information stealer called Arkanix, promoted on dark web forums in late 2025 and likely developed with LLM assistance. The project included a control panel, a Discord community, and two tiers: a Python-based basic build and a VMProtect-wrapped C++ premium variant with enhanced AV evasion and wallet injection. Arkanix features modular data theft from browsers, wallets, Telegram and Discord, plus optional post-exploitation modules; the author removed infrastructure within two months, complicating detection and tracking.

⚠️ Researchers discovered that a compromised npm publish token allowed an attacker to push a modified release of the widely used Cline CLI that added a malicious postinstall script to fetch and run the AI agent OpenClaw. Aside from that new script, package contents and the CLI binary matched the legitimate prior release, making the change easy to miss. The malicious publish was live on the registry for about eight hours on February 17 before it was deprecated and corrected; developers who installed during that window are advised to update Cline and remove OpenClaw if it was not intentionally installed.

⚠️ On February 17, 2026, the npm package cline was maliciously published as cline@2.3.0 using a compromised publish token; the release added a postinstall hook that executed npm install -g openclaw@latest. Installations between 03:26–11:30 PT pulled OpenClaw onto developer machines. Cline has released 2.4.0, deprecated 2.3.0, revoked the token and updated publishing to support OIDC; users are advised to upgrade and remove any unexpected OpenClaw installs, though researchers say overall impact is low since OpenClaw is not inherently malicious and no Gateway daemon was started.

🔐 ESET researchers have identified an Android implant, dubbed PromptSpy, that leverages generative AI to maintain persistence on victims' devices and represents an evolution of earlier VNCSpy samples. The implant sends serialized UI snapshots to Google's Gemini, receives step-by-step Accessibility Service actions to keep the malicious app pinned in Recent Apps, and executes those actions while a VNC module provides remote viewing and control. The initial dropper impersonated JPMorgan Argentina and distributed via mgardownload[.]com; communications use AES-encrypted VNC to a hardcoded C2 at 54.67.2[.]84. PromptSpy also overlays invisible UI elements to block uninstallation; the only reliable removal is rebooting into Safe Mode.
