LICEcap – Record your desktop and create animated GIFs

LICEcap, from Cockos Incorporated, is a nice and free tool that allows you to record your desktop screen activity and later save the activity as an animated GIF. This comes in handy when you are creating a small tutorial of some sort.
The nice thing about LICEcap is that it is not only free but also supports Windows and macOS.

Features and options:

  • Record directly to .GIF or .LCF.
  • Move the screen capture frame while recording.
  • Pause and restart recording, with optional inserted text messages.
  • Global hotkey (shift+space) to toggle pausing while recording
  • Adjustable maximum recording framerate, to allow throttling CPU usage.
  • Basic title frame, with or without text.
  • Record mouse button presses.
  • Display elapsed time in the recording.

Hiew+ – Editing process memory with Hiew hex editor

What’s is Hiew+

Hiew+ is based on the FsPlus project. FsPlus is an implementation of an idea that allows you to access non disk files as if they were disk files. Hiew+ is a real life example of FsPlus where we take Hiew (an excellent hex editor) and turn it into an excellent process editor. Each process will be viewed as a file with a size as much as SYSTEM_INFO.lpMaximumApplicationAddress returns. In theory FsPlus should work with any hex editor to provide process memory editing, but this release is just Hiew ready.

Hiew+ editing the process memory of a process being debugged by IDA Pro

Usage

To use FsPlus, you need to inject FsPlus.dll into Hiew’s process memory so that the APIs are hooked. After APIs are hooked, FsPlus will recognize and treat in a different manner any file name that has the following form: “pid|1234” where 1234 is a given PID. To make the usage even simpler, I provid a small GUI (FsPlusGui) to allow you launch Hiew conveniently.

In fact, Hiew+ can be considered as a nice addition to your reverse engineering tools arsenal (IDA Pro‘s debugger or any other debugger, etc.).

Here’s a screenshot of the FsPlusGui:

You will need to double click on a process to have Hiew or the desired process launched with FsPlus support.
Make sure you specify the settings correctly in FsPlus.ini:

[settings]
title=Hiew+ (c) lallous <lallousz-x86@yahoo.com>
hookdll=.\fsPlus.dll
launch=c:\hiew\hiew32.exe

Features

After you run it successfully, you will be able to start editing processes as if you were editing files. The catch is every process virtual address is now a physical offset in Hiew.

Modules as IMAGE_SECTION_HEADERs

For your convenience we have created additional IMAGE_SECTION_HEADER structures in the PE header of the main process, so that each loaded module is view as a PE section:

Textual information about process’ modules

In addition to viewing modules as PE sections, you will have an actual representation of all loaded modules just after the end of the PE header:

No Read Errors

To avoid reading errors and such, any unreadable memory page is filled with “BAD!” pattern.

Physical and Logical disk editing

This is not something added by FsPlus, rather it is a undocumented feature of Hiew32 where you can use Hiew to edit/view logical and physical disk sectors:

Conclusion

Download – Release date: late 2008

This tool has been tested with Windows Vista (32) and Windows XP SP2 and with Hiew 7.29.
Hope you find this tool useful as Hiew itself.
Note: Please don’t contact me if you run into trouble. This tool is no longer supported.
