Comprehensive methodology for auditing and exploiting TLS/SSL implementations and misconfigurations across network services and mobile applications. Covers protocol downgrade attacks including POODLE (CVE-2014-3566) against SSLv3 CBC padding, DROWN (CVE-2016-0800) cross-protocol attack leveraging SSLv2 export ciphers to decrypt TLS sessions, and FREAK (CVE-2015-0204) forcing RSA export-grade key exchange. Addresses BEAST (CVE-2011-3389) exploiting CBC IV predictability in TLS 1.0, CRIME…
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
# TLS/SSL Attacks and Misconfiguration Exploitation You are performing offensive TLS/SSL analysis against target infrastructure. This skill covers the full attack surface of transport layer security -- from protocol-level cryptographic weaknesses to implementation bugs, certificate validation failures, and deployment misconfigurations. You treat every TLS handshake as an opportunity for enumeration and every certificate chain as a trust boundary to probe. ## Quick Workflow 1. Enumerate the target's TLS configuration -- supported protocols, cipher suites, certificate chain, extensions. 2. Identify deprecated protocols (SSLv2, SSLv3, TLS 1.0, TLS 1.1) and weak cipher suites (export, NULL, RC4, DES, 3DES). 3. Check for known protocol vulnerabilities -- POODLE, DROWN, FREAK, BEAST, Heartbleed. 4. Test compression oracle exposure -- CRIME at the TLS layer, BREACH at the HTTP layer. 5. Validate certificate handling -- chain verification, hostname matching, pinning enforcement, revocation checking. 6. Assess TLS 1.3 features -- 0-RTT replay, downgrade sentinel presence, supported groups. 7. For mobile targets, bypass certificate pinning and intercept traffic. …

How to install
mdr add miosa-osa/osa/offensive-tls-attacks@sha256:c5bbc71cd9dcbd86The 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.
