How a repository gets into this Category

A rule in the AwesomeRepos source code puts a repository in this Category when one of these is true. A machine applies the rule to each repository each hour, and a repository can be in more than one Category. The rule groups repositories by area. It does not rank them and does not say that one is better than another.

One of its topics is 2fa, appsec, auth, authentication, authorization, blue-team, bug-bounty, captcha, crypto, cryptography, ctf, cve, cyber-security, cybersecurity, devsecops, dfir, digital-forensics, encryption, exploit, exploitation, firewall, forensics, fuzzing, hacking, hacking-tool, hash, hashcat, hashing, honeypot, incident-response, or one of 39 more topics.

A topic starts with security-, pentest, malware-, osint-, ctf-.

Its description contains the words “security”, “vulnerability”, “vulnerabilities”, “penetration testing”, “pentest”, “pentesting”, “exploit”, “malware”, “reverse engineering”, “forensics”, “osint”, “cryptography”, “encryption”, “authentication”, “oauth”, “jwt”, “password manager”, “ctf”, “honeypot”, “red team”.
