 There are some heap exploitation tools floating around.
 
-## shadow

-jemalloc exploitation framework: https://github.com/CENSUS/shadow
-
-## libheap
+## Malloc Playground
 
-Examine the glibc heap in gdb: https://github.com/cloudburst/libheap
+The `malloc_playground.c` file given is the source for a program that prompts the user for commands to allocate and free memory interactively.
 
-## heap-viewer
+## Pwngdb
 
-Examine the glibc heap in IDA Pro: https://github.com/danigargu/heap-viewer
+Examine the glibc heap in gdb: https://github.com/scwuaptx/Pwngdb
 
-## heapinspect
+## pwndbg
 
-A Python based heap playground with good visualization for educational purposes: https://github.com/matrix1001/heapinspect
+An exploitation-centric gdb plugin that provides the ability to view/tamper with the glibc heap: https://github.com/pwndbg/pwndbg
 
-## Forkever
+## gef
 
-Debugger that lets you set "checkpoints" as well as view and edit the heap using a hexeditor: https://github.com/haxkor/forkever
