我是计算机安全的新手,但我正在尝试从字典密码开始进行切换大小写攻击的操作。

我读过there,可以从字典开始交替使用大写和小写单词来具有所有组合(区分大小写)。

我不知道要使用什么命令,现在我在标准字典攻击中停止了4
sudo hashcat -m 16800 convertedpcap.16800 dict.txt

有人知道怎么做吗?

这里是完整的帮助(我删除了[[哈希模式]-以节省空间):

最佳答案

简短答案:

从Github上的Hashcat存储库下载toggle5.rule并尝试运行以下命令:

sudo hashcat -m 16800 -r toggle5.rule convertedpcap.16800 dict.txt

hashcat规则说明和演示:

使用旧的切换案例示例链接到newer article推荐规则,特别是rules/中的示例。对于此示例,让我们使用toggle5.rule,该站点解释为“一次包含所有可能的明文位置1到15到... 5个字符的切换选项”。

让我们尝试破解字符串HaShCaT的md5并将其放入我们的example.hash文件(它是41e24266141b6ef98bf0e1fb54b238a1)中,并使用仅字符串hashcat的字典作为example.dict文件。继续使用您喜欢的编辑器在您正在使用的任何文件夹中创建这两个文件。

如果我们只是使用普通的字典攻击,就像这样:
hashcat -a 0 -m 0 example.hash example.dict

它无法破解哈希。没有惊喜。现在添加--stdout标志。
hashcat --stdout -a 0 -m 0 -r toggle5.rule example.dict

您将看到打印出的哈希值,然后是如果我们尝试破解哈希值将要尝试的所有候选对象,在这种情况下,它只是字符串hashcat。注意,使用--stdout时,命令中不需要example.hash。

现在让我们尝试将toggle5.rule添加到
hashcat --stdout -a 0 -m 0 -r toggle5.rule example.dict

我直接从Github存储库复制了规则。多亏了--stdout,它应该在hashcat上打印一个很多变体形式。我们可以通过将其通过less或更好的管道进行管理,使其更加易于管理。
hashcat --stdout -a 0 -m 0 -r toggle5.rule example.dict | sort | uniq -c | sort -rn

基本上,这将显示hashcat的每个变体作为候选者生成的次数。现在,您将看到规则如何为尝试破解哈希生成新的候选者!然后,最终运行...
hashcat -a 0 -m 0 -r toggle5.rule example.hash example.dict

和成功!它破解了md5哈希HaShCaT

现在关于您的问题...

专门针对您所要询问的内容,您可能不需要toggle5.rule提供的所有变体。如果您确定要破解的密码少于15个字符或最多包含4个大写字符,则可以减少变体形式。

例如,如果您只想尝试对每个字母使用交替大小写的候选词,则规则文件将是
T0T2T4T6T8TATCTE
T1T2T5T7T9TBTDTF

hashcat为例,这将生成候选HaShCaThAsHcAt。以防万一这更接近您要寻找的东西。请随时在评论中描述您的特定情况,我们可以共同探讨最有意义的规则。
