A coordinated supply chain compromise of the @asyncapi npm organization delivered malicious payloads through five package versions published via the project's legitimate GitHub Actions OIDC trusted publishing pipeline. The attack originated from a pwn request exploiting a misconfigured pullrequesttarget workflow that exposed the asyncapi-bot PAT, enabling unauthorized commits to auto-publish branches. Unlike typical npm supply-chain attacks, the payload executes at import/require time rather than through lifecycle hooks, bypassing --ignore-scripts mitigations. The second stage fetches an encrypted ~8.2 MB Miasma modular runtime from IPFS, establishing C2 at 85.137.53.71 with OS-specific persistence and decentralized fallback channels.

Kaspersky identified OkoBot, a sophisticated multi-stage malware framework delivered via the TookPS PowerShell downloader and orchestrated over an attacker-controlled SSH tunnel, targeting cryptocurrency users. The framework comprises over 20 interconnected payloads that perform UAC bypass, RDP hijacking, browser-extension based credential theft (Rilide), hardware-wallet seed-phrase phishing (SeedHunter), keylogging, and screen/video capture (OkoSpyware), all coordinated through a plugin dispatcher communicating over HTTP/HTTPS C2 channels. The campaign has been active since at least March 2025, continues to evolve its tooling, and shows indicators (geoblocking, Russian code comments, use of Rilide) consistent with Russian-speaking cybercriminal operators.

Eleven malicious NuGet DotnetTool packages masquerading as game cheats deliver a two-stage Windows payload. The first-stage .NET downloader resolves GitHub hosts via DNS-over-HTTPS to bypass local DNS controls, requests UAC elevation to resync the system clock, and fetches pepesoft.exe from GitHub Releases and Hugging Face. The second-stage PyInstaller-packed Python payload exfiltrates hardware fingerprints, system information, IP geolocation, and screenshots to Google Sheets and Telegram, with a server-side ban-list and hardware binding for licensing enforcement across all recovered builds.

Operation Muck and Load is a supply chain attack campaign centered on a malicious Go module that impersonates a DNS scanner tool to deliver a multi-stage Windows malware loader. The campaign leverages 222 GitHub lure repositories across 190 accounts with automated commit-farming workflows to create false credibility, and uses public dead-drop resolvers across multiple platforms for resilient payload-location resolution. The final payload chain delivers AsyncRAT, Quasar, Remcos, Vidar infostealer, and cryptominers through password-protected 7z archives extracted into masqueraded Microsoft-themed directories.

A coordinated supply-chain campaign published 17 typosquatted npm and PyPI packages mimicking PaySafe, Skrill, and Neteller payment SDKs. The packages implement a fake SDK facade that harvests environment variables containing credentials and tokens, then exfiltrates them over HTTPS to an ngrok-based C2 server. The malware includes sandbox evasion logic and multi-layer C2 domain obfuscation to hinder analysis.

LevelBlue GSOC has identified accelerating ValleyRAT campaigns delivered through fake installers and malicious emails targeting Chinese and Japanese-speaking users. The email-based attack chain uses DLL sideloading via a legitimate VLC executable to load a malicious DLL that downloads an RC4-encrypted, Donut-generated ValleyRAT payload, which is then injected into a suspended rundll32.exe process for fileless execution. The malware incorporates extensive anti-analysis checks (memory size, sleep timing, CPU count, VHD boot detection) and establishes persistence via registry Run keys.

Token Theft and AI Poisoning Redefine the Perimeter Attackers are shifting from breaking passwords to stealing active login sessions, bypassing multi-factor authentication entirely. This week, ARToken and ConsentFix exploited Microsoft 365 OAuth flows to hijack accounts, while Anubis ransomware used the ongoing CitrixBleed 2 vulnerability to steal session tokens from network gateways. Even a standard user can become a Global Administrator in minutes if identity settings are loose, as demonstrated by a recent M365 privilege escalation analysis. Simultaneously, artificial intelligence systems have evolved from helper tools to critical vulnerabilities, serving as both the weapon and the target. Threat actors are using AI to generate malware like InfernoGrabber v9.0 and BusySnake Stealer, while also poisoning AI agent ecosystems with malicious skills like OpenClaw and tricking AI models into executing financial fraud via indirect prompt injection. The AI arms race has accelerated breakout times to under 30 minutes, with state-sponsored groups like GTG-1002 now orchestrating entire espionage campaigns via AI. Defenders must immediately audit identity and session controls, treating session tokens as highly sensitive credentials. Security teams should also implement guardrails for AI agents, verifying external URLs and restricting autonomous financial or code execution actions.

Kaspersky's 2025 compromise assessment report reveals that organizations consistently fail to detect long-dwelling threats, with 30.8% of incidents persisting over 3 months and 52% of high-severity compromises going undetected for 90+ days. Key findings include widespread abuse of LoLBins and remote management tools in every incident-bearing engagement, 40% of web shells surviving in backups to be restored post-remediation, and a strong correlation between in-house forensics/reverse-engineering capability and reduced incident severity. Multiple case studies document dormant crypto-mining on domain controllers (4 years), in-memory LionTail implants on critical servers, PurpleFox rootkit infections evading EDR with disabled memory scanning, and ClipBanker persistence via registry Run keys with Defender exclusions.

The StrikeShark campaign utilizes a novel malware family named SharkLoader to deploy Cobalt Strike Beacons across various global sectors. Threat actors gain initial access by exploiting known vulnerabilities in public-facing applications or distributing custom droppers disguised as legitimate software. SharkLoader employs advanced evasion techniques, including Perfect DLL Hijacking and extensive API hooking, to bypass loader locks and conceal its execution in memory.

Trust Chains Broken at Scale While ClickFix Becomes a Service This week, attackers stopped trying to kick down the front door and instead walked in through the trust chains that hold digital ecosystems together. North Korea's Sapphire Sleet compromised over 140 Mastra npm packages through a single typosquatted dependency, stealing cryptocurrency wallets and planting persistent backdoors on developer machines. The GlassWorm group trojanized Open VSX extensions with WebAssembly malware that uses the Solana blockchain as an unkillable command channel, while SmartApeSG hijacked the Okendo Reviews widget to serve malicious prompts on thousands of e-commerce sites. Even vendor integrations became a liability: the Klue breach exposed Recorded Future client data through a compromised OAuth token connecting a marketing tool to Salesforce. Deception also became an industrial product. The ErrTraffic framework now operates as full Malware-as-a-Service, using blockchain smart contracts to hide its infrastructure and compromised WordPress sites to serve fake error prompts that trick users into running malicious commands. Attackers weaponized trusted AI platforms too—one campaign abused claude.ai's shared chat feature to deliver MacSync infostealer on macOS, while the shai_hulululud npm package uses prompt injection to blind AI-powered security scanners. On the infrastructure side, the FortiBleed campaign cracked credentials for over 73,000 FortiGate firewalls with a 45-GPU cluster, handing attackers valid keys to government and defense networks worldwide. Defenders should immediately hunt for the easy-day-js dependency in their npm projects, reset credentials on any FortiGate firewall, enable Azure AD Graph Activity Logs to close a years-long reconnaissance visibility gap in Microsoft cloud environments, and audit OAuth tokens on all third-party vendor integrations.

Perimeter Auth Collapse and AI-Driven Deception Shift the Battlefield The security perimeter cracked open this week as critical authentication bypasses in Check Point VPNs, Ivanti Sentry, and Palo Alto GlobalProtect gave attackers a free pass into corporate networks, with Qilin ransomware already exploiting one to launch real attacks. At the same time, AI became the year's most versatile weapon: criminals used ChatGPT and Claude brands as phishing lures, researchers proved AI email assistants will hand over corporate secrets to impersonators, and the Shai-Hulud campaign began injecting fake prompts to blind AI-powered security scanners. Patch edge VPN appliances immediately, treat AI agents as high-risk insiders, and hunt for device-code authentication events that bypass normal credential checks.

ANY.RUN's Q1 2026 Cyber Risk Report highlights a significant acceleration in attacker operational tempo, with the median time-to-persistence dropping to 21 seconds and LOTL execution occurring in 16 seconds. The data also shows a marked increase in loader-based attacks, credential theft, and the weaponization of trusted tools via JavaScript LOLBAS techniques, emphasizing the critical need for rapid, behavior-based detection capabilities.

Software Supply Chain and AI Exploitation Dominate Threat Landscape The software supply chain has become the primary battlefield for attackers because compromising a single developer tool can cascade into thousands of enterprise networks. Campaigns like Mini Shai-Hulud and TrapDoor are stealing credentials and injecting backdoors across major code registries, while the Laravel Lang Compromise and the Coruna Exploit Kit show how malicious code can automatically execute to steal secrets or exploit end users. As a result, organizations must treat developer environments as high-value targets, because a single compromised package or malicious VS Code extension can lead to catastrophic breaches like the GitHub internal repository theft by TeamPCP. In parallel, artificial intelligence is simultaneously accelerating attacks and creating dangerous new attack surfaces. Threat actors are using AI to automate influence campaigns like Patriot Bait and crack passwords, while also impersonating AI tools like Gemini CLI and Claude Code to deliver infostealers. Furthermore, attackers are directly targeting exposed AI infrastructure, such as Ollama AI endpoints, and manipulating AI coding assistants via hidden prompt injections in campaigns like TrapDoor, which means AI systems are both the weapon and the target. These trends together suggest that traditional perimeter defenses are failing against supply chain and AI-driven threats. Managers should immediately enforce strict vetting of open-source packages, restrict developer access to unverified extensions, and ensure AI infrastructure is not exposed to the public internet.
