Windows 10 – whoami command .

The whoami is used to display the domain and user name of the person who is currently logged on to this computer.
If used without parameters, whoami displays the current domain and user name.
You can use this command with the next parameters:

/upn Displays the user name in user principal name (UPN) format.
/fqdn Displays the user name in fully qualified domain name (FQDN) format.
/logonid Displays the logon ID of the current user.
/user Displays the current domain and user name and the security identifier (SID).
/groups Displays the user groups to which the current user belongs.
/priv Displays the security privileges of the current user.
/fo <Format> Specifies the output format. Valid values include:

table   Displays output in a table. This is the default value.

list   Displays output in a list.

csv   Displays output in comma-separated value (CSV) format.

/all Displays all information in the current access token, including the current user name, security identifiers (SID), privileges, and groups that the current user belongs to.
/nh Specifies that the column header should not be displayed in the output. This is valid only for table and CSV formats.
/? Displays help at the command prompt.

Some examples with this command:

  • check if we are running elevated : whoami /groups | find “-” ;
  • display all of the information in the current access token: whoami /all ;
  • see what security groups you belong to: whoami /groups ;

Programming with FASM – test with CPUID .

First you need to take a look at this website.
The CPUID returns processor identification and feature information in the EAX, EBX, ECX, and EDX registers.
What the source code from my example do ?
First I start with the default assembly program .
The next step is to strat with reset xor eax,eax use cpuid.
The result of CPUID will be put into EBX.
Into section ‘.data’ data readable writeable make a structure named out_buffer.
The structure will be fill so you need to EBX, see example:
mov [out_buffer.vendor_ebx],ebx will give us “Genu”.
The next step for test EBX is this example:
test edx,00010000000000000000000000000000b
jz .NoHTT
mov [out_buffer.htt_arch4],’YES ‘
.NoHTT:

The structure of out_buffer is :
db ‘NoHTT’,2,9,’- ‘
.htt_arch4 dd ‘NO ‘
db 9,10

Because I used MessageBox to show us the out_buffer.
The result will be : No or Yes with the size of dd.
The db can define byte variables, as well as arrays of bytes.
Fasm documentation tell us: For example db 1,2,3 will define the three bytes of values 1, 2 and 3 respectively.
The dd has 4 bytes.
The result will be this text (the result is true so the text will be YES): “NoHTT – YES”.
Let’s see one screenshot:

This is the source code:
