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.

2 findings: 1 critical severity, 1 medium severity. Installing this skill is not recommended: please review these findings carefully if you do intend to do so.
Detected high-risk code patterns in the skill content — including its prompts, tool definitions, and resources — such as data exfiltration, backdoors, remote code execution, credential theft, system compromise, supply chain attacks, and obfuscation techniques.
The document contains explicit offensive instructions (rogue AP setup, deauthentication, frame injection) and notes techniques enabling data exfiltration and traffic manipulation, which are high-risk abuse patterns that can be used maliciously.
The skill prompts the agent to compromise the security or integrity of the user’s machine by modifying system-level services or configurations, such as obtaining elevated privileges, altering startup scripts, or changing system-wide settings.
The skill explicitly instructs running tools with sudo (hostapd-mana, aireplay-ng, krack-test-client, test-fragattacks) to start rogue APs and perform deauths, which requires elevated privileges and modifies the system/network state.
Low
Low-risk findings.
1 low severity finding. Worth noting, but not necessarily harmful.
The skill fetches instructions or code from an external URL at runtime, and the fetched content directly controls the agent’s prompts or executes code. This dynamic dependency allows the external source to modify the agent’s behavior without any changes to the skill itself.
The skill includes runtime git clone of remote repositories (https://github.com/vanhoefm/krackattacks-scripts and https://github.com/vanhoefm/fragattacks) and immediately runs their scripts (sudo ./krack-test-client.py, sudo ./test-fragattacks.py), meaning fetched remote code is executed and the skill depends on those external repos at runtime.
