Python脚本获取Windows系统密码（NTDS.dit、SAM 和 .SYSTEM ）
运行脚本的基本语法是：
python3 secretsdump.py [domain/]username[:password] -t THREADS -inputfile INPUTFILE [options]
主要论点是：
-t THREADS,--threads THREADS: 并发线程数。将THREADS替换为需要的数量。-inputfile INPUTFILE：包含目标主机列表的文本文件，每行一个。将 INPUTFILE 替换为文件的路径。-outputfile OUTPUTFILE：如果需要，输出目录的路径（可选）。将根据目标、用户名和域（如果指定）在此目录中创建转储文件。将 OUTPUTFILE 替换为您的目录路径。
目标参数遵循以下模式：[domain/]username[:password]。
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 66 67 68 69 70 71 72 73 74 75 76 77 78 79 80 81 82 83 84 85 86 87 88 89 90 91 92 93 94 95 96 97 98 99 100 101 102 103 104 105 106 107 108 109 110 111 112 113 114 115 116 117 118 119 120 121 122 123 124 125 126 127 128 129 130 131 132 133 134 135 136 137 138 139 140 141 142 143 144 145 146 147 148 149 150 151 152 153 154 155 156 157 158 159 160 161 162 163 164 165 166 167 168 169 170 171 172 173 174 175 176 177 178 179 180 181 182 183 184 185 186 187 188 189 190 191 192 193 194 195 196 197 198 199 200 201 202 203 204 205 206 207 208 209 210 211 212 213 214 215 216 217 218 219 220 221 222 223 224 225 226 227 228 229 230 231 232 233 234 235 236 237 238 239 240 241 242 243 244 245 246 247 248 249 250 251 252 253 254 255 256 257 258 259 260 261 262 263 264 265 266 267 268 269 270 271 272 273 274 275 276 277 278 279 280 281 282 283 284 285 286 287 288 289 290 291 292 293 294 295 296 297 298 299 300 301 302 303 304 305 306 307 308 309 310 311 312 313 314 315 316 317 318 319 320 321 322 323 324 325 326 327 328 329 330 331 332 333 334 335 336 337 338 339 340 341 342 343 344 345 346 347 348 349 350 351 352 353 354 355 356 357 358 359 360 361 362 363 364 365 366 367 368 369 370 371 372 373 374 375 376 377 378 379 380 381 382 383 384 385 386 387 388 389 390 391 392 393 394 395 396 397 398 399 400 401 402 403 404 405 406 407 408 409 410 411 412 413 414 415 416 417 418 419 420 421 422 423 424 425 426 427 428 429 430 431 432 433 434 435 436 437 438 439 440 441 442 443 444 445 446 447 448 449 450 451 452 453 454 455 456 457 458 459 460 461 462 463 464 465 466 467 468 469 470 471 | #!/root/venv/bin/python

# Description:
# Performs various techniques to dump hashes from the
# remote machine without executing any agent there.
# For SAM and LSA Secrets (including cached creds)
# we try to read as much as we can from the registry
# and then we save the hives in the target system
# (%SYSTEMROOT%\\Temp dir) and read the rest of the
# data from there.
# For NTDS.dit we either:
# a. Get the domain users list and get its hashes
# and Kerberos keys using [MS-DRDS] DRSGetNCChanges()
# call, replicating just the attributes we need.
# b. Extract NTDS.dit via vssadmin executed with the
# smbexec approach.
# It's copied on the temp dir and parsed remotely.
#
# The script initiates the services required for its working
# if they are not available (e.g. Remote Registry, even if it is
# disabled). After the work is done, things are restored to the
# original state.

# the pieces together, plus some extra magic.
