# Combolist Logs
Combo lists, a.k.a ULPs, are compilations of URL, username, and password information shared on dark web related resources. Due to the nature of these files, they do not include any additional information such as the date of the breach or details about the compromised device. They are simply lists of credentials in URL:USERNAME:PASSWORD format.
The following image contains part of a combo list detected on dark web related resources.
### Difference Between Information Stealer Logs and Combo lists
Information stealer logs include additional data such as IP addresses, host-names, usernames, operating systems, malware paths, files, the date of compromise, and saved credentials from the browsers. In contrast, combo lists are merely lists of credentials without any supplementary information, making them less reliable compared to comprehensive information stealer logs.
