IIM Feeds for adversary infrastructure chains.

IIM chain for Seqrite Operation Dragon Weave, published 2026-05-29. The campaign targets Czech Republic and Taiwan using a spearphishing ZIP with two delivery paths. Path A uses a PDF-masquerading LNK to launch empty.vbs and Profile.ps1, which decrypts 1.dat into RuntimeBroker_update.exe and prepares UnityPlayer.dll plus Com.dat. Path B uses a Rust executable dropper to extract the same sideloading components. Both paths converge on RuntimeBroker_update.exe loading malicious UnityPlayer.dll (RUSTCLOAK), which decrypts Com.dat and executes AZUREVEIL, an Adaptix C2 agent. AZUREVEIL uses Microsoft Azure Blob Storage as dead-drop style C2 through note1ggbbhggdwa1.blob.core.windows.net and the /note/ats/ blob path pattern.

IIM chain for the Wiz Research report published on 2026-05-27 describing JINX-0164 supply-chain activity. The chain models trojanized npm package @velora-dex/sdk version 4.9.1, a malicious dist/index.js addition that decodes and runs a curl command to 89.36.224.5/troubleshoot/mac/install.sh, dropper delivery, MINIRAT macOS payload execution, and the shared datahub.ink / cloud-sync.online / byte-io.us C2 domain set. It intentionally does not invent npm account credentials, unpublished package download telemetry beyond Wiz/StepSecurity references, or a source-repository compromise because Wiz explicitly says the GitHub source code was not modified.

IIM chain for Glassworm as documented by CrowdStrike on 2026-05-26: the operators targeted developers through OpenVSX/VS Code-style extensions, npm and Python packages, and poisoned GitHub repositories. The installed malware delivered Glassworm downloader/RAT capability and resolved operational endpoints through four resilient C2 channels: Solana transaction memo dead-drops, BitTorrent DHT configuration lookup, Google Calendar event-title dead-drops, and direct commercial VPS C2 servers. CrowdStrike, Google and Shadowserver disrupted the channels simultaneously. Exact malicious package names and original VPS C2 addresses were not published in the source article; this chain models the confirmed infrastructure architecture without inventing unpublished IoCs.

IIM chain for the November 2025 Gamaredon zero-click delivery path: a Ukraine-themed RAR archive abuses CVE-2025-6218/CVE-2025-8088 style archive delivery to place an HTA in the Windows Startup folder. The HTA/loader reaches DynDNS-backed delivery infrastructure, retrieves/launches Pteranodon, and then uses Telegram/graph.org dead-drop resolver infrastructure plus DynDNS/Fast-Flux C2 nodes for tasking and payload rotation.

Cisco Talos observed a campaign targeting Czech organizations and workforce-related victims. The chain uses a malicious ZIP, LNK-triggered PowerShell loader, an embedded PowMix payload hidden in the ZIP data blob, and C2 communication via Heroku-hosted infrastructure using REST-like URL paths.

ESET-documented Webworm infrastructure lane using Microsoft Graph / OneDrive for GraphWorm command traffic and Amazon S3 infrastructure for WormFrp-related reconnaissance/exfiltration.

ESET-documented Webworm lane targeting European government entities: malware stages from GitHub repository content and EchoCreep uses Discord API traffic as its C2 channel.

Post-compromise UAT-8302 proxy infrastructure lane using Stowaway and public IP/port C2 or tunnel endpoints from Talos IoCs

Campaign chain for a Ukraine-focused lure targeting FPV/UAV-related audiences. The flow starts with a humanitarian-aid themed archive/LNK and HTA delivery layer on ukrvarta.online, moves through external JavaScript and updater.txt payload staging, persists as OneDriveUpdater, injects a decoded shellcode stage into RuntimeBroker.exe, unpacks EncryptedReverseShell.exe, and communicates with 109.237.97.4:8443.
