Cookie-Monster - BOF To Steal Browser Cookies & Credentials

Steal browser cookies for edge, chrome and firefox through a BOF or exe! Cookie-Monster will extract the WebKit master key, locate a browser process with a handle to the Cookies and Login Data files, copy the handle(s) and then filelessly download the target. Once the Cookies/Login Data file(s) are downloaded, the python decryption script can help extract those secrets! Firefox module will parse the profiles.ini and locate where the logins.json and key4.db files are located and download them. A seperate github repo is referenced for offline decryption.
通过 BOF 或 exe 窃取 edge、chrome 和 firefox 的浏览器 cookie！Cookie-Monster 将提取 WebKit 主密钥，找到带有 Cookie 和登录数据文件句柄的浏览器进程，复制句柄，然后以无文件方式下载目标。下载Cookies/登录数据文件后，python 解密脚本可以帮助提取这些机密！Firefox 模块将解析profiles.ini并找到 logins.json 和 key4.db 文件所在的位置并下载它们。引用单独的 github 存储库进行脱机解密。

BOF Usage BOF 用法

Usage: cookie-monster [ --chrome || --edge || --firefox || --chromeCookiePID <pid> || --chromeLoginDataPID <PID> || --edgeCookiePID <pid> || --edgeLoginDataPID <pid>] 
cookie-monster Example: 
   cookie-monster --chrome 
   cookie-monster --edge 
   cookie-moster --firefox 
   cookie-monster --chromeCookiePID 1337
   cookie-monster --chromeLoginDataPID 1337
   cookie-monster --edgeCookiePID 4444
   cookie-monster --edgeLoginDataPID 4444
cookie-monster Options: 
    --chrome, looks at all running processes and handles, if one matches chrome.exe it copies the handle to Cookies/Login Data and then copies the file to the CWD 
    --edge, looks at all running processes and handles, if one matches msedge.exe it copies the handle to Cookies/Login Data and then copies the file to the CWD 
    --firefox, looks for profiles.ini and locates the key4.db and logins.json file 
    --chromeCookiePID, if chrome PI   D is provided look for the specified process with a handle to cookies is known, specifiy the pid to duplicate its handle and file
    --chromeLoginDataPID, if chrome PID is provided look for the specified process with a handle to Login Data is known, specifiy the pid to duplicate its handle and file  
    --edgeCookiePID, if edge PID is provided look for the specified process with a handle to cookies is known, specifiy the pid to duplicate its handle and file
    --edgeLoginDataPID, if edge PID is provided look for the specified process with a handle to Login Data is known, specifiy the pid to duplicate its handle and file

EXE usage EXE 用法

Cookie Monster Example:
  cookie-monster.exe --all 
Cookie Monster Options:
  -h, --help                     Show this help message and exit

  --edge                         Extract edge keys and download Cookies/Login Data file to PWD
  --chrome                       Extract chrome keys and download Cookies/Login Data file to PWD
  --firefox                      Locate firefox key and Cookies, does not make a copy of either file
