A chained exploit comprising three zero-day vulnerabilities in Siemens ROX II OT switches allows an attacker to escalate from arbitrary file disclosure to full persistent root-level access. CVE-2025-40948 leverages a root-privileged xz utility to read any file on the filesystem, CVE-2025-40947 exploits unsanitized input in the feature key signature verification to achieve command injection as root, and CVE-2025-40949 enables persistent code execution by injecting commands into the root cron table via the web management task scheduler. Siemens has released firmware V2.17.1 to address all three vulnerabilities.

The HelloNet campaign is an active APT operation targeting large Russian organizations through the ViPNet secure networking software suite. Attackers achieve persistence by placing a malicious wtsapi32.dll in the ViPNet Update System directory, which is sideloaded by itcsrvup64.exe at OS startup. The loader (HelloInjector) injects into svchost.exe and deploys a modular toolkit including a network proxy, command executor, log cleaner, and a Rust-based backdoor. The campaign uses renamed PuTTY/Plink utilities for SSH reverse tunneling to C2 servers and employs IOCTL hooking to evade user-mode security solutions.

A global phishing campaign active since late March 2026 deploys heavily obfuscated JScript droppers that launch LuaJIT or AutoIt-based loaders disguised as TrueType Font (.ttf) files to deliver multiple RATs and infostealers including Agent Tesla, Remcos, XWorm, and a Snake Keylogger variant dubbed Best Private LOGGER. The Lua loader leverages LuaJIT's Foreign Function Interface to call native Windows APIs for in-memory shellcode execution, employing advanced evasion techniques such as decoy memory allocation, Donut header patching, AMSI/ETW bypass, API unhooking, and VEH-based segmented shellcode decryption. The campaign has evolved from October 2025 through June 2026 with progressively more sophisticated anti-analysis capabilities.

Between January and June 2026, Iran integrated AI technologies as a force multiplier across its hybrid warfare model — cyber operations, influence operations, military systems, and domestic surveillance — without fundamentally altering its asymmetric strategic doctrine. Iranian state-sponsored threat actors (APT42, MuddyWater, APT34, and others) leveraged LLMs to accelerate malware development, enhance spearphishing lures, and conduct ICS reconnaissance, while AI-generated propaganda and inauthentic social media accounts flooded the information environment at unprecedented scale. Russia likely transferred AI-enabled Shahed drone variants and operational tactics to Iran, though independent confirmation of AI use in 2026 kinetic operations remains limited.

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.

ESET researchers identified 11 old, Microsoft-signed UEFI shim bootloaders (version 0.9 and below) that can bypass UEFI Secure Boot on any system trusting Microsoft's third-party UEFI CA 2011 certificate. The old shims lack modern security features (MokListX enforcement, SBAT) and contain known vulnerabilities (CVE-2026-10797) that enable revocation bypass, allowing attackers to execute untrusted code during boot and deploy UEFI bootkits. Exploitation does not require the affected software to be installed — attackers can bring their own copy of the vulnerable shim to any UEFI system with the Microsoft third-party certificate enrolled.

Cofense Intelligence reports a significant evolution in finance-themed phishing from Q1 2025 to Q1 2026, with threat actors shifting from urgency-driven subject lines to operational business language that mirrors routine financial workflows. By Q1 2026, 79% of finance-themed phishing campaigns used operational language rather than pressure tactics, making them harder to distinguish from legitimate correspondence and more likely to bypass SEGs. The campaigns leverage three main lure categories — New Business, Contracts in Progress, and Payments — and deliver credential phishing via embedded URLs and QR codes in PDF attachments.

Symantec identified renewed activity of Backdoor.Daxin, a sophisticated China-linked kernel-mode rootkit that hijacks legitimate TCP connections for covert C2, on a Taiwan manufacturing subsidiary in May 2026, four years after its initial public disclosure. Alongside it, researchers discovered a new backdoor, Stupig, which abuses the Windows keyboard-layout provider mechanism to execute SYSTEM-level commands from the logon screen pre-authentication and hook credential-handling APIs within winlogon.exe. Compile timestamps on both tools date to 2013 despite the host having no telemetry until 2026, suggesting a potentially decade-plus dwell time enabled by likely initial access via an outdated, end-of-life Digiwin SSO/JDK deployment.

ASEC identified a multi-component Linux malware campaign targeting poorly managed SSH servers. The attack chain uses Go-based propagation malware to worm-like spread XMRig CoinMiner across SSH-accessible servers. The XMRig variant implements robust persistence via systemd services, cron jobs, and a /dev/shm watchdog, while XHide and Shc-compiled obfuscation scripts disguise mining activity by spoofing process names and hijacking common administrative commands through .bashrc aliases.

Socket's Threat Research Team identified four compromised npm packages in the @asyncapi namespace delivering a multi-stage botnet loader called Miasma. The attack injects obfuscated JavaScript into package source files that executes at module load time (bypassing npm lifecycle script blocking), spawns a detached Node.js process to download an encrypted payload from IPFS, and deploys a 3+ MB tasking framework with multi-channel C2 capabilities including HTTP, Nostr, IPFS, and Ethereum RPC. The malicious packages were published via GitHub Actions trusted publishing from a compromised source commit on the 'next' branch.

A phishing campaign distributing SnakeKeylogger is using emails disguised as project proposals to deliver JavaScript malware inside compressed attachments. Upon execution, the JS malware invokes PowerShell to decrypt and load an encrypted SnakeKeylogger payload in memory without writing to disk. The infostealer then harvests browser data, system information, and keylogging data, exfiltrating it via SMTP or Telegram to attacker-controlled infrastructure.

An Initial Access Broker is exploiting CVE-2025-5777 (CitrixBleed 2), a pre-authentication memory overread in Citrix NetScaler ADC/Gateway, to steal session tokens and bypass MFA. The stolen sessions are used to access Citrix published desktops, followed by a consistent privilege escalation via a registry symbolic-link LPE tool that abuses the Windows AppMgmt service and Group Policy refresh to gain SYSTEM. The operator then creates backdoor admin accounts, installs rogue ScreenConnect/Zoho Assist RMM clients, moves laterally with PsExec and Impacket, and ultimately deploys DragonForce ransomware. The full kill chain from initial access to encryption was observed completing in under one hour in at least one case.

A multi-stage attack campaign uses malicious LNK files delivered via booking-themed phishing emails to deploy a Node.js-based backdoor. The LNK files use bigint arithmetic obfuscation to reconstruct C2 URLs, download a PowerShell payload that deploys a legitimate node.exe binary, and execute an AES-128-CBC encrypted JavaScript backdoor. The backdoor retrieves its C2 address from the TON blockchain using the EtherHiding technique, employs a custom bytecode VM interpreter for defense evasion, and supports downloading and executing additional payloads including PE files, PowerShell, and JavaScript.

Backdoor.Mistic is a new stealthy backdoor deployed in cybercrime intrusions since April 2026, using DLL sideloading via legitimate MpExtMs.exe and masquerading as EndpointDlp.dll. It executes payloads in memory with a self-deleting kill switch, enabling long-term covert access. Mistic is likely linked to Woodgnat (aka KongTuke), an initial access broker whose ModeloRAT toolkit has been used in attacks delivering Qilin ransomware, connecting this backdoor to the broader ransomware ecosystem.

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.

An active multi-stage phishing campaign distributes AsyncRAT and Remcos RATs through weaponized Excel attachments targeting sales, procurement, and vendor management staff globally. The infection chain uses VBA macros to retrieve HTA payloads via URL shorteners and Cloudflare Workers, with final payloads hidden via PNG steganography and loaded filelessly into memory via .NET assembly loading. The campaign demonstrates high-volume, automated payload generation with consistent obfuscation patterns including Base64 encoding, character substitution, and string reversal.

UNK_DeadDrop is a likely North Korean threat actor conducting broad phishing campaigns targeting software developers with fake job offers and code review requests. The campaign delivers malicious GitHub/GitLab repositories that abuse VS Code and Cursor IDE task automation to silently execute cross-platform malware. Linux and macOS systems receive the Overlord Go RAT with custom credential and wallet theft modules, while Windows runs a fileless Node.js/Python pipeline inside the editor's Electron process. The malware exfiltrates cryptocurrency wallets, browser credentials, and OS keychain data to a hardcoded C&C server at 23.137.105.75:5173.

Threat actors are weaponizing AI-themed lure documents to deliver a complex multi-stage infection chain culminating in AsyncRAT and a custom .NET RAT called clay_Client. The attack uses hidden LNK files inside compressed archives to initiate a chain of PowerShell scripts that extract, decrypt, and execute payloads from disguised PDF containers using AES-CBC, XOR, and GZip decompression. AutoHotkey scripts perform process hollowing into legitimate .NET Framework executables, while defense evasion includes adding Microsoft Defender exclusions and restoring disabled VBS execution. The final RAT provides full remote control with screen capture, input simulation, fileless assembly loading, and process injection capabilities.

FortiGuard Labs identified an ongoing Ousaban banking Trojan campaign targeting users in Spain and Portugal, delivered via phishing PDFs that redirect victims to geofenced malicious webpages. The attack chain involves a VBS script extracting a ZIP payload from a steganographic image, with the final Ousaban EXE establishing persistence via registry Run keys and communicating with C2 servers resolved through daily-changing DDNS hostnames. The malware targets over 25 Spanish and Portuguese financial institutions and employs a custom encryption algorithm shared with the Casbaneiro family to evade detection.

The Q2 2026 trend report from AhnLab ASEC documents a significant expansion of attack surfaces into AI stacks, identity infrastructure, and public-facing applications. CISA KEV listings rose 27% year-over-year to 75 entries, with ransomware-linked vulnerabilities nearly doubling. Notable developments include prompt injection-to-RCE chains in Microsoft Semantic Kernel, data exfiltration via M365 Copilot Enterprise (SearchLeak), three Microsoft Defender zero-days used for telemetry evasion, and continued AI supply chain attacks via malicious skills. The report recommends shifting from signature-based to behavior-based detection and implementing ITDR, conditional access, and AI-specific input validation controls.

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.

Malicious Chrome and Firefox browser extensions masquerading as free VPN tools ('VPN Go: Free VPN') were distributed via official extension marketplaces and later updated to include clipboard-stealing functionality. The extensions monitor clipboard contents on a timer, chunk copied text into ~1000-character segments, and exfiltrate data via HTTP GET requests to hardcoded attacker-controlled IP addresses using a /html/continue.php endpoint with uid, part, total, and data query parameters. Both extensions share infrastructure, code patterns, and build artifacts, confirming a common threat actor. The staged update pattern—initial versions functioning as legitimate proxy tools with later versions adding clipboard theft—highlights the risk of extension update supply chain compromise.
