The registry run keys perform the same action, and can be located in different locations:
- Attempts to identify installed analysis tools by a known file location;
- Checks for the presence of known devices from debuggers and forensic tools;
- Detects the presence of Wine emulator via registry key;
- Detects Sandboxie using a known mutex;
- Checks for a known DeepFreeze Frozen State Mutex;
- Collects information to fingerprint the system. There are behavioral human characteristics that can be used to digitally identify a person to grant access to systems, devices, or data. Unlike passwords and verification codes, fingerprints are fundamental parts of user’s identities. Among the threats blocked on biometric data processing and storage systems is spyware, the malware used in phishing attacks (mostly spyware downloaders and droppers), ransomware, and Banking Trojans as posing the greatest danger.

Win32/Kryptik.GHEO popup alert may wrongly claim to be acquiring from a legislation enforcement institution and will report having located child porn or various other illegal information on the tool. The alert will similarly contain a requirement for the individual to pay the ransom money.
