Modlishka is a flexible and powerful reverse proxy, that will take your ethical phishing campaigns to the next level. It was realeased with an aim to:

  • Help penetration testers to carry out an effective phishing campaign and reinforce the fact that serious threat can arise from phishing.
  • Show current 2FA weaknesses, so adequate security solutions can be created and implemented soon.
  • Raise community awareness about modern phishing techniques and strategies.
  • Support other open source projects that require a universal reverse proxy.

Some of the most important ‘Modlishka’ features :

  • Support for majority of 2FA authentication schemes (by design).
  • No website templates (just point Modlishka to the target domain – in most cases, it will be handled automatically).
  • Full control of “cross” origin TLS traffic flow from your victims browsers (through custom new techniques).
  • Flexible and easily configurable phishing scenarios through configuration options.
  • Pattern based JavaScript payload injection.
  • Striping website from all encryption and security headers (back to 90’s MITM style).
  • User credential harvesting (with context based on URL parameter passed identifiers).
  • Can be extended with your ideas through plugins.
  • Stateless design. Can be scaled up easily for an arbitrary number of users – ex. through a DNS load balancer.
  • Web panel with a summary of collected credentials and user session impersonation (beta).
  • Backdoor free ;-).
  • Written in Go.


Latest source code version can be fetched from here (zip) or here (tar).

Fetch the code with ‘go get’ :

$ go get -u

Compile the binary and you are ready to go:

$ cd $GOPATH/src/
$ make

./dist/proxy -h

Usage of ./dist/proxy:
-cert string base64 encoded TLS certificate
-certKey string base64 encoded TLS certificate key
-certPool string base64 encoded Certification Authority certificate
-config string JSON configuration file. Convenient instead of using command line switches.
-credParams string Credential regexp collector with matching groups. Example: base64(username_regex),base64(password_regex)
-debug Print debug information
-disableSecurity Disable security features like anti-SSRF. Disable at your own risk.
-jsRules string Comma separated list of URL patterns and JS base64 encoded payloads that will be injected.
-listeningAddress string Listening address (default “”)
-listeningPort string Listening port (default “443”)
-log string Local file to which fetched requests will be written (appended)
-phishing string
Phishing domain to create – Ex.:
-plugins string Comma seperated list of enabled plugin names (default “all”)
-postOnly Log only HTTP POST requests
-target string Main target to proxy – Ex.:
-targetRules string Comma separated list of ‘string’ patterns and their replacements.
-targetRes string Comma separated list of target subdomains that need to pass through the proxy
-terminateTriggers string Comma separated list of URLs from target’s origin which will trigger session termination
-terminateUrl string URL to redirect the client after session termination triggers
Enable TLS (default false)
-trackingCookie string
Name of the HTTP cookie used to track the victim (default “id”)
-trackingParam string
Name of the HTTP parameter used to track the victim (default “id”)
