Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# Evil Twin / KARMA / Mana

Stand up an AP that looks like (or is more attractive than) the legitimate target. Clients associate, you become their gateway, you intercept everything. The classic "captive portal at the airport" attack pattern, scaled to whatever the engagement requires.

## Quick Workflow

1. Discover target ESSID(s) clients are looking for (PNL — Preferred Network List)
2. Stand up rogue AP advertising matching ESSID(s)
3. (Optional) Deauth clients off legitimate AP to push them toward yours
4. Run captive portal / transparent MITM
5. Capture creds, deliver payload, or harvest sessions

---

## Variants

| Variant | Mechanic | Use Case |
|---|---|---|
| **Evil Twin** | Same ESSID + BSSID as legit AP | Open or PSK-known networks (ISP cafe Wi-Fi, public guest) |
| **KARMA** | Respond "yes" to every probe request | Clients with broad PNLs (most older devices) |
| **Mana** | Respond selectively to probes per-client | KARMA-aware MAC randomization defenses |
| **Known Beacons** | Beacon a list of likely-known ESSIDs | Wide-net attraction without seeing probes first |
| **Captive Portal** | Force splash page on association | Phishing, payload delivery |

How to install

The exact contents, by fingerprint
mdr add miosa-osa/osa/offensive-evil-twin@sha256:dc71dc4ba63cf7fd

The line at the top of this page pins the label git:20260913.e13b6b8, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
