Which user-created evidence source can help investigators analyze malicious links?

Internet bookmarks serve as valuable user-created evidence sources for investigators analyzing malicious links because they provide a record of the websites that a user has actively saved for quick access. Bookmarks can reveal the user's browsing habits, the specific sites they intended to revisit, or links they may have been researching at the time of an incident.

When investigating incidents related to cyber threats, examining bookmarks can show whether users have accessed suspicious or known malicious URLs. This information can help establish a timeline of user activity and can indicate potential sources of compromise. Investigators can also cross-reference these bookmarks with databases of known malicious links to understand better if the user was targeted or inadvertently involved in a phishing attack.

In contrast, while application logs, email attachments, and database entries can provide useful information, they do not specifically capture the direct user interaction with links in the same way that bookmarks do. Application logs may provide activity details but typically lack the context of user intentions regarding specific URLs. Email attachments might contain malicious content, but they do not track user navigation. Database entries offer structured information but may not relate to browsing history or user-specific web interactions.
