Adversaries may acquire credentials from web browsers by reading files 
specific to the target browser.(Citation: Talos Olympic Destroyer 2018) Web 
browsers commonly save credentials such as website usernames and passwords 
so that they do not need to be entered manually in the future. Web browsers 
typically store the credentials in an encrypted format within a credential 
store; however, methods exist to extract plaintext credentials from web 
browsers.

The following Atomic test utilizes LaZagne to extract passwords from 
browsers on the Windows operating system.LaZagne is an open source 
application used to retrieve passwords stored on a local computer.

The following Atomic test utilizes WebBrowserPassView to extract passwords 
from browsers on a Window system. WebBrowserPassView is an open source 
application used to retrieve passwords stored on a local computer. Recently 
noticed as a tool used in the BlackCat Ransomware.

Adversaries may acquire credentials from web browsers by reading files 
specific to the target browser.[1] Web browsers commonly save credentials 
such as website usernames and passwords so that they do not need to be 
entered manually in the future. Web browsers typically store the 
credentials in an encrypted format within a credential store; however, 
methods exist to extract plaintext credentials from web browsers.

Kimsuky has used browser extensions including Google Chrome to steal 
passwords and cookies from browsers. Kimsuky has also used Nirsoft's 
WebBrowserPassView tool to dump the passwords obtained from 
victims.[39][40][41][42]

OilRig has used credential dumping tools such as LaZagne to steal 
credentials to accounts logged into the compromised system and to Outlook 
Web Access.[63][64][65][66] OilRig has also used tool named PICKPOCKET to 
dump passwords from web browsers.[66]

Once we have administrative remote shell, our next task is to gather all 
the passwords from Security Accounts Manager (SAM) database, Local Security 
Authority Subsystem (LSASS) process memory. Domain Active Directory 
Database (domain controllers only), Credential Manager (CredMan) store or 
LSA Secrets in the registry and get all the passwords (clear-text or 
hashed). A lot of stuff has already been mentioned at Obtaining Windows 
Passwords and Dumping Windows Credential and Bernardo Blog Dump Windows 
password hashes efficiently Part1 , Part2, Part3, Part4, Part5 and Part6.

Metasploit provide a post exploitation module for taking snapshots from 
webcam and recording sounds from microphone. Imagine, the impact of 
informing the client that we can view a person live-feed or record sounds 
from a meeting room without being present in the same room. Maybe in the 
meeting there were discussing about passwords, company secrets, operations, 
future plannings, spendings, etc.

We took this modified Mimikatz file and ran it against systems running 
up-to-date versions of Windows Defender, Symantec, and ESET. (Thanks to 
Brian Fehrman and David Fletcher). We were able to run the script to dump 
cleartext passwords from memory and it was not detected by AV.

SAM is short for the Security Account Manager which manages all the user 
accounts and their passwords. It acts as a database. All the passwords are 
hashed and then stored SAM. Using CME, we will dump the credentials from 
SAM in the form of hashes by using the following command:

Method 1. Use the in-memory dowload and execute: Use below command to 
execute a PowerShell script from a remote shell, meterpreter native shell, 
a web shell etc. and the function exported by it. All the scripts in 
Nishang export a function with same name in the current PowerShell session.

The ransomware appends a random extension to infected files and uses 
Salsa20 encryption. It uses some tricks to avoid detection, such as a new 
defence evasion technique, known as reflective DLL loading, to inject a DLL 
from memory.

The NetWalker malware uses a custom resource type (1337 or 31337) 
containing its entire configuration. This file is extracted to memory and 
decrypted using the RC4 algorithm with a hard-coded key in the resource.

Mimikatz is an open-source leading post-exploitation tool that makes 
post-exploitation lateral movement within a network easy for attackers. It 
was developed in 2007 by the French developer, Benjamin Delpy to gather 
credentials. This tool dumps passwords from memory, hashes, PINs, and 
Kerberos tickets. A wide range of operations related to penetration testing 
can be performed by Mimikatz.
