Dump Memory Segment From Process Memory and Rebuild So(Elf) Binaries

• v0.5:
  • 1. Added Option to Use PID instead of Package Name(Use new Option: -i or --pid)
  • 2. Added 64bit Elf Fixing(Please use 64bit dumper for 64bit processes)
  • 3. Few Things Fixed

• No need of Ptrace
• Bypass Anti Debugging
• Fix and Regenerate Elf Binaries
• Dumping of Lib from Memory of Process
• Auto Dumping With Segment Name
• Manual Dumping With Custom Memory Address
• Support Fast Dumping(May Miss some data due to limitations of syscalls)

• You can Use latest precompiled Binaries from HERE or You Can build your Own.
• Needs Root Access or Virtual Space
• Get Root Shell through Adb or Terminal Apps(type: 'su') or Normal Shell into Virtual Space via Terminal Apps
• For Usage Help: ./memdumper -h
• For General Usage: ./memdumper -p <option(s)> -o

    Help: ./memdumper -h
