Constructor Details

#initialize(name, opts) ⇒ Target

Initializes an instance of a bruteforce target from the supplied information. The hash of options that this constructor takes is as follows:

Platform

The platform(s) that this target is to operate against.

SaveRegisters

The registers that must be saved by NOP generators.

Arch

The architectures, if any, that this target is specific to (E.g. ARCH_X86).

Bruteforce

Settings specific to a target that supports brute forcing. See the BruteForce class.

Ret

The target-specific return address or addresses that will be used.

Payload

Payload-specific options, such as append, prepend, and other values that can be set on a per-exploit or per-target basis.

DefaultOptions

DefaultOptions hash to be imported into the datastore.
