Analysis Options

Cutter will use the underlying radare2 analysis options to analyze a binary. These options are usually configured when the binary is first loaded. However, they can be later changed using the Analysis dialog, and a new analysis that takes these options into account can then be performed.

Analysis Dialog

Analysis dialog

Description: The Analysis dialog allows setting some radare2’s analysis options. The supported options are described below.

Clicking on the “Analyze Program” button will trigger an analysis of the current binary with radare2’s aaa command, taking into account the configured values of the analysis options.

Steps to open: Edit -> Preferences -> Analysis

Search boundaries for analysis

Select the boundaries in which the analyis will be performed. The different options are:

  • All executable maps (io.maps.x)

  • All maps (io.maps)

  • Current map (io.map)

  • Raw (raw)

  • Current mapped section (bin.section)

  • All mapped sections (bin.sections)

Configuration variable: anal.in

Speculatively set a name for the functions

Try to name functions without symbols by using artifacts in the functions such as API calls and strings.

Configuration variable: anal.autoname

Search for new functions following already defined functions

Cutter will check if there is a candidate for a new function following an already defined one, as the compiler usually state them together. This option is taking the advantages of both Recursive Analysis and Linear Sweep into some kind of a hybrid mode. For each discovered function, the analysis will try to check for a function-prologue, usually following a gap of null bytes or cc bytes. This will help with discovering functions which are not referenced in the program. As such, it will make the analysis slower and prone to false-positives.

Configuration variable: anal.hasnext

Create references for unconditional jumps

When encountering unconditional jumps during the analysis, Cutter will add a code-reference even if it is not guaranteed that the jump will take place.

Configuration variable: anal.jmp.ref

Analyze jump tables in switch statements

When encountering switch statements during analysis, continue and analyze the target blocks of the jump tables.

Configuration variable: anal.jmp.tbl

Analyze push + ret as jmp

When performing analysis of a function, treat the sequence of push followed by ret instruction as a jmp. This can help Cutter to continue the analysis to target of the jmp.

Configuration variable: anal.pushret

Show verbose information when performing analysis

When enabled, Cutter will print warnings it encountered while preforming analysis. These warnings can help the user understand if anything went wrong in the analysis. This function is not only helpful when trying to perform a full analysis of the program, but also when trying to analyze and define new functions.

Configuration variable: anal.verbose

Verbose output from type analysis

Print warnings encountered while preforming type analysis. These warnings can help the user understand if anything went wrong in the analysis.

Configuration variable: anal.types.verbose

Pointer depth

The maximum number of nested pointers to follow in analysis.

Configuration variable: anal.ptrdepth

Functions prelude

Hex value that represents certain opcodes that will be used to identify functions.

Configuration variable: anal.prelude
