1- Symbol Tables Replace Profiles

In Volatility 2, the use of memory profiles was mandatory. Analysts had to first identify the OS profile using:

volatility -f memdump.mem imageinfo

Then, they used that profile with every subsequent plugin invocation:

volatility -f memdump.mem --profile=Win7SP1x64 pslist

Volatility 3 eliminates this requirement. Instead, it uses symbol tables, which are modular representations of OS structure metadata. These symbol tables are automatically matched or can be manually specified, removing the need for brittle profile matching and increasing compatibility with diverse memory images.

2- Plugin Names Are OS-Specific

In Volatility 2, plugins were generic and reused across operating systems, relying on the selected profile to determine behavior.

In Volatility 3, plugins are OS-specific and names are prefixed accordingly, improving clarity and modularity. For example:

• pslist → windows.pslist, linux.pslist, mac.pslist
• svcscan → windows.svcscan

This design improves cross-platform support and reduces ambiguity.

3- CLI Syntax Overhaul

The overall command-line syntax in Volatility 3 is Python-native and more explicit. You now run commands like this:

python3 vol.py -f memdump.mem windows.pslist

Instead of the older v2-style command:

volatility -f memdump.mem --profile=Win7SP1x64 pslist
