[RST] NetRipper - Smart traffic sniffing for penetration testers

Recommended Posts

Description

NetRipper is a post exploitation tool targeting Windows systems which uses API hooking in order to intercept network traffic and encryption related functions from a low privileged user, being able to capture both plain-text traffic and encrypted traffic before encryption/after decryption.

NetRipper was released at Defcon 23, Las Vegas, Nevada.

Abstract

The post-exploitation activities in a penetration test can be challenging if the tester has low-privileges on a fully patched, well configured Windows machine. This work presents a technique for helping the tester to find useful information by sniffing network traffic of the applications on the compromised machine, despite his low-privileged rights. Furthermore, the encrypted traffic is also captured before being sent to the encryption layer, thus all traffic (clear-text and encrypted) can be sniffed. The implementation of this technique is a tool called NetRipper which uses API hooking to do the actions mentioned above and which has been especially designed to be used in penetration tests, but the concept can also be used to monitor network traffic of employees or to analyze a malicious application.

Da, e in CrackMapExec, insa nu i-a mai facut update de o gramada de timp. :( 

L-am cunoscut pe byt3bl33d3r la BlackHat Asia, e super de treaba, a zis ca o sa ii faca update, dar probabil a uitat. Poate ii mai aduc eu aminte. :D 

 

Este si in PTF, dar la fel, nu e updated :( https://github.com/trustedsec/ptf/tree/master/modules/windows-tools

NetRipper combinat cu celebra tehnica ARP Spoofing cumva... toate datele dintr-o retea is pe tava? Sau delirez eu si-mi scapa ceva? :))

Nop, e necesar sa ruleze pe masina care timite/primeste trafic. Doar la nivel de retea, daca se verifica certificatele cum trebuie, nu se poate face nimic.
