Gobuster
Directory/File, DNS and VHost busting tool written in Go
Gobuster is a tool used to brute-force. This project is born out of the necessity to have something that didn't have a fat Java GUI (console FTW), something that did not do recursive brute force, something that allowed me to brute force folders and multiple extensions at once, something that compiled to native on multiple platforms, something that was faster than an interpreted script (such as Python), and something that didn't require a runtime. Provides several modes, like the classic directory brute-forcing mode, DNS subdomain brute-forcing mode, the mode that enumerates open S3 buckets and looks for existence and bucket listings, and the virtual host brute-forcing mode (not the same as DNS!). Since this tool is written in Go you need to install the Go language/compiler/etc. Full details of installation and set up can be found on the Go language website. Once installed you have two options. You need at least go 1.16.0 to compile gobuster. -

andOTP
Open source two-factor authentication for Android
Open source two-factor authentication for Android. It implements Time-based One-time Passwords (TOTP) and HMAC-Based One-Time Passwords (HOTP).

This project started out as a fork of the great OTP Authenticator app written by Bruno Bierbaumer, which has sadly been inactive since 2015. By now almost every aspect of the app has been changed/re-written so the fork status of the Github repository got detached upon user request. But all credit for the original version and for starting this project still goes to Bruno. -

Fail2Ban
Daemon to ban hosts that cause multiple authentication errors
Fail2ban scans log files (e.g. /var/log/apache/error_log) and bans IPs that show the malicious signs -- too many password failures, seeking for exploits, etc. Generally Fail2Ban is then used to update firewall rules to reject the IP addresses for a specified amount of time, although any arbitrary other action (e.g. sending an email) could also be configured. Out of the box Fail2Ban comes with filters for various services (apache, courier, ssh, etc). Fail2Ban is able to reduce the rate of incorrect authentications attempts however it cannot eliminate the risk that weak authentication presents. Configure services to use only two factor or public/private authentication mechanisms if you really want to protect services. -
