A combo list is a text file that contains leaked usernames and passwords in a consistent format. These files are commonly fed into automatic brute-forcing tools that test multiple credentials on different accounts or website logins until a match is found.
These old data sets are still valuable to threat actors, as they can be used for credential-stuffing attacks. Earlier this month, a collection of re-released combo lists was made available on the dark web.
What is a Combo List?
A combo list is a list of data items. It can be a text file or a dynamically created table. These lists can be sorted or unsorted.
Combo lists are not that interesting from a security standpoint because they are full of duplicate records. In many cases, duplicates of duplicates. It’s also important to note that these old passwords still matter, such as SpyCloud analysts published content on this subject in light of the epidemic of password reuse.
Like List boxes, Combo boxes have an Edit box that allows the user to select from the list. They can also enter text into the Edit box. This text will be returned to your application as a character string. If your application needs to read the value of an item from a combo box, you can handle the event.
When the event occurs, you can set the selected item or index and retrieve the property’s value on the selected item. If the selected item is a data item in a table, you can also use it to get the property’s value on that data item.
The most straightforward use of a combo box is to display a list of values and let the user select one. However, you may also want to allow users to change their selection. For example, you can enable the user to add custom values to a drop-down list or choose a font size.
To do this, you can create a list of items, bind the list to a table, and let the user edit the data in the table. In addition, you can make the data visible or hidden.
You can add a selection to a combo box list by clicking, tapping, or pressing Enter on an item. The list then commits the user’s choice, and the list closes. The user can also navigate the empty list with the keyboard arrow keys.
In a combo box, the selected value is stored in the ‘SelectedItem’ property of the combo box. This property can be accessed by the SelectedItem property of the combo box or by using a combo box’s Properties object.
If you have a combo list that displays items from a named range in a table, you can set the property to match the name of the named field. This way, the combo box can display items from a named range located on another worksheet in the same workbook.
Alternatively, you can create a combo box that displays dependent drop-down lists based on a dynamic named range. For this type of combo box, the code is different.
When a combo box is bound to a named range, you can set its Column Widths property to 0.5″;2″. This will hide the first column in the designated field. Then, you can use the Table column widths property to resize it to a different width, if necessary.
Combo Lists are a Text File
A combo list is a text file that contains a collection of usernames and passwords in a consistent format. They are often used in automated tools that perform automated authentication requests to websites and APIs. They may also be used for credential stuffing attacks that try multiple credentials on a website or service.
They are an excellent way to access usernames and passwords that were leaked in data breaches or stolen from other sources so that they can be used for various attack vectors, such as credential stuffing, account takeovers, targeted phishing, impersonation, business email compromise, and extortions. It’s important to understand that these files are not always in cleartext, and some may contain encrypted hashes.
The main reason that these files are so valuable is that they are often found in large numbers, and they can be reused over and over again. This is because users reuse their passwords across accounts and slightly modify their existing passwords.
Some combination lists contain over one billion unique user logins and passwords, which makes them a gold mine of information. S
Combo lists can be helpful, particularly in the case of a large-scale breach that results in millions of unique user IDs and passwords being disclosed. However, they are only sometimes a must-have.
A typical combo list includes a mixture of different types of PII data, such as email addresses, usernames, and passwords. It may also have other information, such as account creation date, country of origin, phone number, birth date, and gender. They are typically a few kilobits or megabytes in size and can be exchanged through email or disk.
While they are the fabled “Mirror Opt-Out” and the “Bold, Italic and Bold Text Mover,” there are no real winners in the category of the most impressive combo list. Other combinations of the same PII could be considered more interesting, but they are likely to make headlines from a technical standpoint.
