Signatures

Tries to load missing DLLs

Signatures

Creates a process in suspended mode (likely to inject code)

Spawns processes

Signatures

Allocates memory with a write watch (potentially for evading sandboxes)

May sleep (evasive loops) to hinder dynamic analysis

Signatures

Creates guard pages, often used to prevent reverse engineering and debugging

Signatures

Sample monitors window changes (e.g. starting applications), analyze the sample with the 'Simulates keyboard and window changes' cookbook

Signatures

Queries the cryptographic machine GUID

Reads software policies

Execution Graphs are highly condensed control flow graphs which give the user a synthetic view of the code detected during Hybrid Code Analysis. They include additional runtime information such as the execution status which is highlighted with different colors and shapes.

Entrypoint

Program entry point, most likely the entry point of the PE file.

Key Decision

A code location where a decision has been made to avoid execution of potentially malicious behavior.

Dynamic / Decrypted

Code which has been generated at runtime, often referred to as unpacked or self-modifying code.

Unpacker / Decrypter

Code section which is responsible for unpacking or decrypting a portion of dynamic code.

Executed

Code which has been executed at runtime.

Not Executed

Code which has not been executed at runtime.

Unknown

Code for which it is unknown if it has been executed or not at runtime.

Signature Matched

Code which matches a behavioral signature.

Rich Path

Path through the execution graph which shows a lot of behavior (e.g. with respect to called API functions).

Thread / callback entry

Code corresponding to a thread or callback entry point.

Thread / callback creation

Edges denoting either a thread creation (e.g. using CreateThread) or a callback registration (e.g. EnumWindows).

Entrypoint

VBA program entry point such as Document_Open.

Decryption Function

Function likely responsible for string decryption.

Executed

This line was executed during analysis.

Not Executed

This line was likely not executed during analysis.
