BetterCap – Modular, Portable MiTM Framework

BetterCAP is a powerful, modular, portable MiTM framework that allows you to perform various types of Man-In-The-Middle attacks against the network. It can also help to manipulate HTTP and HTTPS traffic in real-time and much more.

BetterCap has some pretty impressive Spoofing abilities with multiple host discovery (just launch the tool and it will start discovery), ARP spoofing, DNS spoofing and ICMP doubledirect spoofing.

The other tool similar to this would be: MITMf – Man-In-The-Middle Attack Framework and specfically for SSL you have sslsniff v0.7 – SSL Man-In-The-Middle (MITM) Tool.

Features

Some of the main features include:

• Full and half duplex ARP spoofing.
• The first real ICMP DoubleDirect spoofing implementation.
• Configurable DNS spoofing.
• Realtime and completely automatized host discovery.
• Realtime credentials harvesting for protocols such as HTTP(S) POSTed data, Basic and Digest Authentications, FTP, IRC, POP, IMAP, SMTP, NTLM ( HTTP, SMB, LDAP, etc ) and more.
• Fully customizable network sniffer.
• Modular HTTP and HTTPS transparent proxies with support for user plugins + builtin plugins to inject custom HTML code, JS or CSS files and URLs.
• SSLStripping with HSTS bypass.
• Builtin HTTP server.

Why not Ettercap?

Ettercap still has some plus points like you can see connections and raw pcap stuff, but it’s not all relevant to everyone. Mostly it’s show its’ age and BetterCap doesn’t have the below cons:

• Ettercap was a great tool, but it’s old
• Ettercap filters do not work most of the times
• Ettercap filters are outdated
• Ettercap filters are hard to implement due to the implementation language.
• Ettercap is unstable on big networks (try host discovery on a network bigger than /24)
• Ettercap is hard to extend or add modules to unless you’re a C/C++ developer.
• Ettercap’s and MITMf’s ICMP spoofing is completely useless in 2016.
• Ettercap does not provide a builtin and modular HTTP(S) transparent proxy.
• Ettercap does not provide a smart and fully customizable credentials sniffer.

You can download BetterCap via the Ruby gem system so:

Should get you there.
