memhack is an easy to use, small console based memory scanner. This tool can search process memory for strings,values. It can detect changes in memory and flag them as incremented or decremented. A useful query functionality exists where users can mask search/detection queries to achieve what they need. It can read/write to process memory where allowed.
Example use:
In less than 5 steps, the user can alter their score in Solitaire.
Enter process id.
Scan for current score value.
Detect change in memory, make a move in the game that changes score.
The steps above should narrow down the search results to 3-10 items.
Next, either do another scan change, or simple search for the new score.
Display the memory address that holds the score value,
Overwrite.
Profit.
