Adversaries may acquire credentials from web browsers by reading files specific to the target browser.
Web browsers commonly save credentials such as website usernames and passwords so that they do not need to be entered manually in the future.
Web browsers typically store the credentials in an encrypted format within a credential store.

Detects exploitation of LNK file command-line length discrepancy, where attackers hide malicious commands beyond the 260-character UI limit while the actual command-line argument field supports 4096 characters using whitespace padding (e.g., 0x20, 0x09-0x0D).
Adversaries insert non-printable whitespace characters (e.g., Line Feed \x0A, Carriage Return \x0D) to pad the visible section of the LNK file, pushing malicious commands past the UI-visible boundary.
The hidden payload, executed at runtime but invisible in Windows Explorer properties, enables stealthy execution and evasion—commonly used for social engineering attacks.
This rule flags suspicious use of such padding observed in real-world attacks.

Detects deletion attempts of MacOS Time Machine backups via the native backup utility "tmutil".
An adversary may perform this action before launching a ransonware attack to prevent the victim from restoring their files.

Detects the addition of a new file or path exclusion to MacOS Time Machine via the "tmutil" utility.
An adversary could exclude a path from Time Machine backups to prevent certain files from being backed up.

Detects potentially suspicious execution of the Qemu utility in a Windows environment.
Threat actors have leveraged this utility and this technique for achieving network access as reported by Kaspersky.

Detects the enabling of the Windows Recall feature via registry manipulation.
Windows Recall can be enabled by deleting the existing "DisableAIDataAnalysis" value, or setting it to 0.
Adversaries may enable Windows Recall as part of post-exploitation discovery and collection activities.
This rule assumes that Recall is already explicitly disabled on the host, and subsequently enabled by the adversary.

This rule assumes that Recall is already explicitly disabled on the host, and subsequently enabled by the adversary.
Detects the dump of highly sensitive files such as "NTDS.DIT" and "SECURITY" hive.
Attackers can leverage the "wbadmin" utility in order to dump sensitive files that might contain credential or sensitive information.

Detects the recovery of files from backups via "wbadmin.exe".
Attackers can restore sensitive files such as NTDS.DIT or Registry Hives from backups in order to potentially extract credentials.
