offensive-krack-fragattacks skillA

offensive-krack-fragattacks is agent-read markdown (skill) from snailsploit/claude-red: KRACK (CVE-2017-13077..082) and FragAttacks (CVE-2020-24586..588 + 26139-26147) — key reinstallation, fragmentation, and aggregation attacks against WPA2 supplicants. Covers Vanhoef's test scripts, viability against modern patched stacks (mostly mitigated post-2021), residual unpatched embedded devices and IoT vendors, and the practical limitations of these attacks in modern engagements. Use when assessing legacy supplicants, embedded clients, or vendors with poor patch cadence..

Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.

What the file says

# KRACK & FragAttacks

Two attack families against WPA2 client implementations. Both well-disclosed (KRACK 2017, FragAttacks 2021) and largely patched on modern OSes — but the embedded/IoT long tail keeps them in scope for many engagements.

## When These Apply

| Family | Target | Patch Status |
|---|---|---|
| KRACK | WPA2 supplicants in 4-way handshake / GTK / FT / TDLS | Major OSes patched 2017–2018 |
| FragAttacks | Frame fragmentation/aggregation across WPA2/3 | Most stacks patched 2021–2022 |

Probability of success today is high only against:
- Embedded OEM devices (cameras, sensors, point-of-sale)
- Old Android phones (<8 unpatched)
- Industrial / SCADA Wi-Fi clients
- Wi-Fi-enabled toys, smart bulbs, no-name IoT

Modern Win11 / iOS 16+ / Android 13+ / hostapd-2.10 are mitigated.

## KRACK — Key Reinstallation

The 4-way handshake's M3 retransmission causes the supplicant to reinstall the same PTK with reset nonce/replay counters. Frames encrypted under the reused keystream become decryptable.

```bash
# Vanhoef's official test scripts
