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.
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
# 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 git clone https://github.com/vanhoefm/krackattacks-scripts cd krackattacks-scripts/krackattack …

How to install
mdr add snailsploit/claude-red/offensive-krack-fragattacks@sha256:12dea4e775fa3f28The line at the top of this page pins the label git:20260506.c7b211b, 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.
