Many malware families store configuration, payloads, encryption keys, C2 addresses, or other operational data in Registry keys, such as QakBot storing configuration in a randomly named subkey under HKCU\Software\Microsoft and PolyglotDuke writing encrypted JSON configuration files to the Registry. | The content repeatedly describes threat actors and malware modifying, creating, deleting, or storing data in Windows Registry keys and values for persistence, configuration storage, defense evasion, credential access, privilege escalation, and execution.

Bundlore can persist via a LaunchAgent. Calisto adds a .plist file to the /Library/LaunchAgents folder to maintain persistence. CoinTicker creates user launch agents named .espl.plist and com.apple.[random string].plist to establish persistence.

The content repeatedly describes malware and threat actors establishing persistence by adding values under HKCU/HKLM\Software\Microsoft\Windows\CurrentVersion\Run or RunOnce, and by placing executables, scripts, .lnk files, or .bat files in the Windows Startup folder.
